WASHINGTON, Dec. 8, 2020 /PRNewswire/ --The gene therapy etranacogene dezaparvovec substantially increased production of the blood clotting protein factor IX among 52 patients in the largest and most inclusive hemophilia B gene therapy trialto date. The trial is also the first to include patients with certain immune system markers and found that they did not appear to confer any increased risks, a finding that could significantly broaden the number of patients who may be eligible for gene therapy.

A majority of trial participants (96%) successfully discontinued factor IX replacement therapy after receiving the gene therapy and have been producing their own factor IX for six months. The findings suggest gene therapy could, with a single treatment, give patients the ability to maintain factor IX levels and reduce or eliminate the need for additional factor IX replacement therapy, according to researchers.

"Most patients with hemophilia B are bound to a prophylactic factor regimen of one to two intravenous infusions per week from birth through the rest of their life," said senior study authorSteven W. Pipe, MD,of the University of Michigan, Ann Arbor. "Gene therapy offers the chance to liberate patients from the burden of their prior treatments, allowing for spontaneity and the freedom to do more in day-to-day life."

Hemophilia B, which accounts for about one-fifth of hemophilia cases, is caused by an inherited mutation of the gene for factor IX. Lacking the ability to produce the blood clotting factor IX, patients with hemophilia B can suffer uncontrolled bleeding, including internal and joint bleeding that leads to joint deterioration and chronic pain.

Factor IX replacement therapy can reduce bleeding associated with hemophilia B, but it requires weekly or biweekly infusions to maintain factor IX levels, a burdensome regimen that costs several hundred thousand dollars per year. In gene therapy, viral particles are used to shuttle engineered genes to cells in the liver. These genes replace the patient's faulty factor IX gene, allowing the patient's own body to produce factor IX on an ongoing basis. While several gene therapies for hemophilia have shown promise in early phase trials, the study is the first phase III trial to test the approach in a large and diverse array of patients, said Dr. Pipe.

Fifty-four patients enrolled in the study; all were dependent on factor IX replacement therapy, and 70% had bleeding episodes in the six months prior to the study despite this prophylactic treatment. After receiving the etranacogene dezaparvovec gene therapy via a single infusion lasting roughly one hour, factor IX activity increased rapidly from a baseline of up to 2% (moderate to severe hemophilia) to a mean of 37% (very mild hemophilia) at 26 weeks, meeting the trial's primary endpoint. At that level, a patient's bleeding risk is essentially the same as someone without hemophilia, Dr. Pipe noted.

Seventy-two percent of patients reported no bleeding events in the 26 weeks after receiving the gene therapy. "This tells us that the bleeding phenotype can be corrected through this treatment, which is a remarkable achievement," said Dr. Pipe. Fifteen patients experienced some bleeding, which the researchers indicate is not unexpected given that many of the patients had severely affected joints entering the trial.

"What we've seen from patients in the study is that they really don't have to think about their hemophilia anymore," said Dr. Pipe. "The transformative nature that we hear from the patient stories is, to me, the most important outcome from this study."

The trial is also the first to attempt gene therapy in patients with neutralizing antibodies, a component of the immune system that helps the body fight pathogens. About 40% of trial participants had antibodies to adeno-associated virus serotype 5, or AAV5, the viral vector used in etranacogene dezaparvovec. "In any other trial protocol, these patients would not have been eligible to participate," Dr. Pipe noted.

Previous trials have excluded such patients from gene therapies that use viral vectors under the assumption that antibodies could either block the uptake of the viral vectors in the liver or trigger a dangerous immune response to the therapy. The trial found no evidence of either problem, suggesting neutralizing antibodies do not preclude successful gene therapy.

Two patients did not respond to the gene therapy. One did not receive a full dose because the infusion was stopped after the patient showed signs of a reaction to the infusion. The other had a level of neutralizing antibodies about five times higher than any other patient. Since other patients with neutralizing antibodies responded well to the therapy regardless of their level of antibodies, this finding suggests antibodies may pose a problem only at extremely high levels.

No treatment-related serious adverse events were reported. Adverse events were relatively common, occurring in 68% of patients, but most were mild and related to the infusion itself. Nine patients showed evidence of an immune response to the therapy, which was resolved in all cases with a course of corticosteroids.

The researchers will continue to follow patients for five years. Patients will be assessed for sustained factor IX production and effective bleed control over 52 weeks, as well as patient-reported outcome measures to assess impact on quality of life.

Steven W. Pipe, MD, University of Michigan, Ann Arbor, will present this study during the Late-Breaking Abstracts session on Tuesday, December 8 at 7:00 a.m. Pacific time on the ASH annual meeting virtual platform.

Gene Therapy for Hemophilia B Found Safe and Effective in First Phase III Trial - PRNewswire

One of the ways scientists hope to offer better treatments for vision loss is through gene therapy, where carefully selected genetic material is injected into the eyes to address mutations. Researchers have been left surprised by the effectiveness of an experimental form of this treatment, which involved an injection into one eyeball yet improved vision across both.

Gene therapies have the potential to treat all kinds of health conditions, ranging from cancer, to diabetes in dogs, to obesity and damaged spinal cords. One area where we're seeing some really exciting progress is in hereditary vision loss, with studies demonstrating the potential of gene therapy to treat color blindness, progressive retinal diseases and glaucoma, with some recently receiving approval from the FDA.

This latest study was conducted by scientists at the University of Cambridge, the University of Pittsburgh and Paris Institut de la Vision, and focuses on a form of inherited vision loss called Leber hereditary optic neuropathy (LHON). This affects around one in 30,000 people and usually occurs in young folks aged in their 20s and 30s, destroying their retinal ganglion cells and in turn the optic nerve. Once the condition takes hold, vision can deteriorate to the point where the subject is considered legally blind in just a matter of weeks, with recovery occurring in less than 20 percent of cases.

The majority of patients suffer from the same mutation affecting the MT-ND4 gene, so the researchers were hopeful of targeting this mutation as a way of improving treatment outcomes for sufferers of LHON. They trialed their gene therapy as part of a study involving 37 patients who had suffered vision loss in the preceding six to 12 months. This meant injecting a viral vector packed with a modified complementary DNA called rAAV2/2-ND4 into the vitreous cavity at the back of just one eye, with a sham treatment injected into the other eye.

We expected vision to improve in the eyes treated with the gene therapy vector only, says study author Dr Yu-Wai-Man. Rather unexpectedly, both eyes improved for 78 percent of patients in the trial following the same trajectory over two years of follow-up.

To investigate the reasons behind this unexpected outcome, the team studied the gene therapys effects in macaques, which have a similar vision system to humans. This enabled them to analyze the tissues from different parts of the eye to see how the viral vector DNA had spread. This provided evidence of interocular diffusion, with the viral vector DNA turning up in the retina, optic nerve and anterior segment of the untreated eye.

As someone who treats these young patients, I get very frustrated about the lack of effective therapies, says senior investigator Dr Sahel, from the University of Pittsburgh. These patients rapidly lose vision in the course of a few weeks to a couple of months. Our study provides a big hope for treating this blinding disease in young adults.

The research was published in the journal Science Translational Medicine.

Shares in Rocket Pharmaceuticals have been living up to their name, shooting up following encouraging early-stage clinical trial results from a gene therapy for a serious inherited rare heart disease.

Results came from a phase 1 trial of RP-A501 for treatment of Danon Disease and sent shares up 75% on the Nasdaq to more than $56, a five-year high.

The surging stock price indicates the markets confidence in gene therapy products after the successful launch of products such as Roche/Spark Therapeutics Luxturna, a gene therapy for a rare inherited eye disease.

Danon Disease is a rare X-linked disorder caused by genetic mutations in the LAMP2 gene and the therapy works by instructing the body to express a healthy copy of the LAMP2B protein in order to correct the condition.

The disease that affects boys and men more severely causes accumulation of autophagosomes tiny structures that cause cells internal structures to break down in the heart muscle and other tissues.

Together with a build-up of glycogen this can lead to severe and frequently fatal degradation of the heart muscle.

RP-A501 could be the first gene therapy for the disease and the early data showed a positive increase in cardiac protein expression.

As of November, three patients have been treated with a low dose of the therapy and two have been treated with a high dose.

An early trial readout showed two patients with LAMP2B expression that was 50% more than normal, measured nine and 12 months after treatment.

A 15%-20% increase could lead to clinically meaningful improvements in cardiac function and the trial reported a 50% decrease in a key biomarker of heart failure.

There was also a reduction in myocardial cell disarray and a visible reduction in autophagic vacuoles, a hallmark of the disease.

The company also noted stabilisation of three other measures a heart failure biomarker known as BNP, plus levels of transaminases and creatine kinase that also indicate skeletal and heart muscle damage.

However one patient who received the highest dose and had a degree of immunity to the adeno-associated virus used in the therapy had an immune reaction classified as a serious adverse event.

Rocket said the event was likely due to complement activation, resulting in reversible thrombocytopenia and acute kidney injury requiring a short round of haemodialysis.

The patient returned to baseline within three weeks and regained normal kidney function.

DrBarry Greenberg, director of the Advanced Heart Failure Treatment Program atUC San Diego Health, Professor of Medicine atUC San Diego School of Medicine, and the principal investigator said: Children with Danon Disease live with a heavy disease burden. Young boys are often severely afflicted.

They show evidence of early onset skeletal muscle weakness and heart disease that can progress rapidly to end-stage with death occurring on the average before age 20. A heart transplant can be performed but is not curative and is associated with its own significant problems.

The results-to-date for this first investigational gene therapy for monogenic heart failure show the potential for direct clinical benefit without emergence of unanticipated side effects of therapy.

The company has also begun a stock offering of $175 million in shares to fund further development following the results.

Study results from an open-label, single-dose, multi-center, multinational phase III trial, presented during the late-breaking abstract session of the all-virtual 62nd American Society of Hematology (ASH) Annual Meetings show that etranacogene dezaparvovec (previously known was AAV5-hFIXco-Padua; AMT-061; uniQure/CSL Behring), an investigational gene therapy for hemophilia B, is safe and effective.

The two most common types of hemophilia are hemophilia A, in which patients is lack of clotting Factor VIII, and hemophilia B, caused by a lack of the ability to produce the blood clotting factor IX as the result of an inherited mutation of the gene for factor IX.

Both types of hemophilia can lead to spontaneous and uncontrolled bleeding into muscles, organs, and joints as well as prolonged bleeding following injuries or surgery, which leads to joint deterioration and chronic pain.

Hemophilia B, which accounts for about one-fifth of hemophilia cases.

Clinical trialThe study of etranacogene dezaparvovec recruited adult male patients with severe or moderate-severe hemophilia B.

The results of the study demonstrated that a single administration of the gene therapy etranacogene dezaparvovec led to sustained increases of Factor IX to functionally curative levels capable of eliminating the need for regular infusions to control and prevent bleeding episodes. As a result, most patients were able to stop intensive intravenous regimens. The studys authors believe that the results may open doors for patients previously not included in gene therapy trials.

Blood clotting proteinIn the trial included 52 patients and is the largest and most inclusive hemophilia B gene therapy trial to date. The trial is also the first to include patients with certain immune system markers and found that they did not appear to confer any increased risks, a finding that could significantly broaden the number of patients who may be eligible for gene therapy.

A majority of trial participants (96%) successfully discontinued factor IX replacement therapy after receiving the gene therapy and have been producing their own factor IX for six months. The findings suggest gene therapy could, with a single treatment, give patients the ability to maintain Factor IX levels and reduce or eliminate the need for additional factor IX replacement therapy, according to researchers.

Gene therapy offers the chance to liberate patients from the burden of their prior treatments, allowing for spontaneity and the freedom to do more in day-to-day life, Pipe added.

Replacement therapyFactor IX replacement therapy can reduce bleeding associated with hemophilia B, but it requires weekly or biweekly infusions to maintain factor IX levels, a burdensome regimen that costs several hundred thousand dollars per year.

In gene therapy, viral particles are used to shuttle engineered genes to cells in the liver. These genes replace the patients faulty factor IX gene, allowing the patients own body to produce factor IX on an ongoing basis.

About 40% of trial participants had antibodies to adeno-associated virus serotype 5, or AAV5*, the viral vector used in etranacogene dezaparvovec.

Note* Adeno-associated virus serotype 5- (AAV5-) based gene therapies have been demonstrated to be safe and well-tolerated in a multitude of clinical trials. Etranacogene dezaparvovec consists of an AAV5 viral vector carrying a gene cassette with the patent-protected Padua variant of Factor IX (FIX-Padua). The investigational agent has been granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration and access to the Priority Medicines (PRIME) regulatory initiative by the European Medicines Agency.

ASH 2020: Novel Gene Therapy Found to be Safe and Effective in Treatment of Hemophilia B - OncoZine

bluebird bio has presented long-term data from its Zynteglo one-time gene therapy for the blood disorder beta-thalassaemia, as the company continues talks with payers in Europe to bring the ultra-pricey treatment to market.

The European Medicines Agency (EMA) has granted a conditional marketing authorisation for the drug that will be marketed as Zynteglo (betibeglogene autotemcel), meaning its licence must be renewed each year until confirmatory data is available.

Results announced at the American Society of Hematology could help bluebird make the case for the long-term use of the therapy as the treatment approaches the market in Europe.

In the US, Zynteglo has hit a speed-bump with the FDA, which is asking for more information about production facilities before a review of clinical data can begin.

Of the 10 patients enrolled in the ongoing long-term study (LTF-303) from a phase 3 programme, 9/10 (90%) were transfusion independent (TI) and all these patients remain transfusion independent.

David Davidson, chief medical officer at bluebird, said: All of the patients in our phase 3 studies who achieved transfusion independence have maintained it, with the durability of the treatment effect underscored by patients from our earlier studies reaching their five-year anniversaries of freedom from transfusions.

In a group of patients aged under 18 from the Northstar-2 and Northstar-3 phase 3 studies, 87% (13 out of 15) achieved TI and remained so.

In a long-term follow-up 53% of patients who achieved TI and restarted iron chelation have since stopped and 30% who achieved TI now receive phlebotomy to reduce iron levels.

Davidson added: Transfusion independence has been observed in paediatric, adolescent and adult patients and across genotypes suggesting outcomes with this gene therapy may be consistent regardless of age or genotype.

In Europe bluebird has set a price of up to $1.58 million euros for a single shot.

This is paid in instalments, with 315,000 euros paid up front and four additional payments due only if the treatment continues to be effective.

Zynteglo is already launched in Germany and is nearing the end of its year of free pricing.

But its fair to say that the therapy wont come cheaply even though most member states will likely end up negotiating a lower price.

In England, cost-effectiveness body NICE is reviewing Zynteglo and is due to publish draft document early in the new year.

Although its too early to say how the review will go, NICE will be looking for more certainty on the long-term effects of the therapy.

The latest data wont be part of the submission to NICE, but the company hopes that an ongoing review of the cost-effectiveness bodys methodology will help novel gene therapies get to market.

Nicola Redfern, general manager of bluebird bio UK, is hopeful that NICE will refine its existing Quality Adjusted Life Year (QALY) and find better ways to deal with uncertainties in clinical data.

How we deal with uncertainties is going to be fundamentally important, she said.

Another issue to address is the discount rate NICE uses to calculate the value of medicines and their long-term impact on patients lives.

The 3.5% discount rate currently used means that these benefits reduce quickly over time in the view of NICE and Redfern agrees with NICEs own proposals to adopt the 1.5% discount rate used by the Treasury.

We agree with NICE that there is already evidence to bring it in line with the rate in the Treasury Green Book.

Bluebird trumpets long-term data from beta-thalassaemia gene therapy - - pharmaphorum

This weekend brought some really significant news in the long-running effort to use gene editing to treat human disease. As most readers will have heard, Boston Childrens Hospital and a Vertex/CRISPR effort both published papers in the NEJM addressing sickle-cell anemia and beta-thalassemia. (Update: edit to fix attribution).

These diseases have long been linked when it comes to gene therapy ideas, because both of them have defects in the hemoglobin protein as their cause. And its long been thought that both could be treated by getting adults to re-express the fetal hemoglobin protein its on a different gene entirely, and thus does not have any of the genetic problems that affect the adult hemoglobin gene. The normal course of events is for babies to stop expressing the fetal form and switch over to regular hemoglobin, and its been worked out that a particular transcription factor called BCL11a is a key player in that transcriptional repression of the fetal hemoglobin gene. That plays right into the usual way that we tend to think about therapeutic possibilities: whether its enzymes, receptors, or expression of whole proteins, we have a lot more tools to mess things up and interrupt processes than we have to make them run faster or better. So the possibility of interrupting BCL11as function has been a tempting one for many years.

Its hard to do by traditional means, though. (Full disclosure: I have, at different times in my career, been involved with such efforts, but none have ever come near the clinic.) Transcription factors are notoriously hard to get a handle on with small molecule therapeutics, and many unsuccessful runs have been taken at BCL11a ligands to try to interrupt its functions in one way or another. My general impression is that the protein doesnt much care about recognizing small-molecule ligands (and its far from the only one in that category, for sure). Youd think that if you ran a few hundred thousand (or a few million) various molecules past any given protein that youd find a few of them that bind to it, but that assumption is too optimistic for most transcription factors. Youre also going to have a hard row to hoe (to use an old Arkansas expression) if you try to break up their interactions with their DNA binding sites: a significant amount of capital has gone down the chute trying to get that to work, with (as far as I can tell) not much to show for it.

Theres another complication: BCL11a has a lot of other functions. Every protein has a lot of other functions, but for transcription factors, the issue can be especially fraught. If you had a small molecule that really did interfere with its activity, what would happen if you just took a stiff dose of it? Probably a number of things, including some interesting (and not necessarily welcome) surprises. There have been a number of ideas about how to get around this problem, but a problem it is.

So its on to biological mechanisms. The BCH team reports on using RNA interference to do the job they get cells to express a short hairpin RNA that shuts down production of BCL11a protein, with some microRNA work to target this to the right cell lines. And the Vertex/CRISPR team, naturally, uses CRISPR itself to go in and inactivate the BCL11a gene directly. Both approaches take (and have to take) a similar pathway, which is difficult and expensive, but still the best shot at such therapies that we have. You want the fetal hemoglobin expressed in red blood cells, naturally, and red blood cells come from CD34+ stem cells in the bone marrow. Even if you havent thought about this, you might see where its going: you take a bone marrow sample, isolate these cells, and then do your genetic manipulation to them ex vivo. Once youve got a population of appropriately re-engineered cells ready to go, you go kill off the bone marrow in the patient and put the reworked cells back in, so theyre the only source there for red blood cells at all. A bone marrow transplant, in other words a pretty grueling process, but definitely not as much as having some sort of blood-cell-driven cancer (where the therapy uses compatible donor cells from someone else without such a problem), or as much as having full-on sickle cell disease or tranfusion-dependent thalassemia.

You can also see how this is a perfect setup for gene therapy: theres a defined population of cells that you need to treat, which are available in a specific tissue via a well-worked-out procedure. The problem youre trying to correct is extremely well understood in fact, it was the first disease ever characterized (by Linus Pauling in 1949) as purely due to a genetic defect . And the patients own tissue is vulnerable to chemotherapy agents that will wipe out the existing cell population, in another well-worked-out protocol, giving the newly reworked cells an open landscape to expand in. You have the chance for a clean swap on a defined target, which is quite rare. In too many other cases the problem turns out to involve a fuzzy mass of genetic factors and environmental ones, none of which by themselves account for the disease symptoms, or the tissue doesnt allow you to isolate the defective cells easily or doesnt allow you to clear them out for any new ones you might generate, and so on.

Both the Vertex/CRISPR and BCH techniques seem to work and in fact, to work very well. There are now people walking around, many months after these treatments, who were severely ill but now appear to be cured. Thats not a word we get to use very often. They are producing enough fetal hemoglobin, more than enough to make their symptoms completely disappear no attacks, no transfusions, just normal life. And so far there have been no side effects due to the altered stem cells. An earlier strategy from Bluebird (involving addition of a gene for a modified adult hemoglobin) also seems to be holding up.

These are revolutionary proofs of concept, but at the same time, they are not going to change the course of these diseases in the world not right now, anyway. Bone marrow transfusion is of course a complex process that costs a great deal and can only be done in places with advanced medical facilities. But what weve established is that anything that can cause fetal hemoglobin to be expressed should indeed cure these diseases that idea has been de-risked. As has the general idea of doing such genetic alteration in defined adult tissues (either RNA interference or CRISPR). From here, we try to make these things easier, cheaper and more general, to come up with new ways of realizing these same goals now that we know that they do what we hoped that they would. This work is already underway new ways to target the affected cell populations rather than flat-out chemotherapy assault, new ways to deliver the genetically altered cells (or to produce them on site in the patients), ways to make the switchover between the two more gradual, and so on. There are lot of possible ways, and we now know where were going.

Gene Therapy, Absolutely and For Real | In the Pipeline - Science Magazine

CAMBRIDGE, Mass.--(BUSINESS WIRE)--bluebird bio, Inc. (Nasdaq: BLUE) announced that new data from Group C of its ongoing Phase 1/2 HGB-206 study of investigational LentiGlobin gene therapy (bb1111) for adult and adolescent patients with sickle cell disease (SCD) show a complete elimination of severe VOEs and VOEs between six and 24 months of follow-up. These data are being presented at the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, taking place virtually from December 5-8, 2020.

Now with more than two years of data, we continue to observe promising results in our studies of LentiGlobin for SCD that further illustrate its potential to eliminate the symptoms and devastating complications of sickle cell disease. Consistently achieving the complete resolution of severe vaso-occlusive events (VOEs) and VOEs between Month 6 and Month 24 follow-up is unprecedented other than with allogeneic stem cell transplantation. Importantly, our data show the potential for LentiGlobin for SCD to produce fundamentally disease-modifying effects with sustained pancellular distribution of gene therapy-derived anti-sickling HbAT87Q and improvement of key markers of hemolysis that approach normal levels, said David Davidson, M.D., chief medical officer, bluebird bio. In addition to these clinical outcomes, for the first time with a gene therapy we now have patient-reported outcomes through the validated PROMIS-57 tool, showing reduction in pain intensity at 12 months after treatment with LentiGlobin for SCD. These results provide insight into the potential real-life impact LentiGlobin for SCD may offer patients.

SCD is a serious, progressive and debilitating genetic disease. In the U.S., the median age of death for someone with sickle cell disease is 43 46 years. SCD is caused by a mutation in the -globin gene that leads to the production of abnormal sickle hemoglobin (HbS). HbS causes red blood cells to become sickled and fragile, resulting in chronic hemolytic anemia, vasculopathy and unpredictable, painful VOEs.

In the HGB-206 study of LentiGlobin for SCD, VOEs are defined as episodes of acute pain with no medically determined cause other than a vaso-occlusion, lasting more than two hours and severe enough to require care at a medical facility. This includes acute episodes of pain, acute chest syndrome (ACS), acute hepatic sequestration and acute splenic sequestration. A severe VOE requires a 24-hour hospital stay or emergency room visit or at least two visits to a hospital or emergency room over a 72-hour period, with both visits requiring intravenous treatment.

LentiGlobin for SCD was designed to add functional copies of a modified form of the -globin gene (A-T87Q-globin gene) into a patients own hematopoietic (blood) stem cells (HSCs). Once patients have the A-T87Q-globin gene, their red blood cells can produce anti-sickling hemoglobin (HbAT87Q) that decreases the proportion of HbS, with the goal of reducing sickled red blood cells, hemolysis and other complications.

As a hematologist, I regularly see the debilitating effects of pain events caused by sickle cell disease. Pain has an overwhelmingly negative impact on many facets of my patients lives and can lead to prolonged hospitalizations, said presenting study author Alexis A. Thompson, M.D., professor of pediatrics at Northwestern University Feinberg School of Medicine and head of hematology at Ann and Robert H. Lurie Childrens Hospital of Chicago. The results observed with LentiGlobin gene therapy for SCD include the complete elimination of severe vaso-occlusive pain episodes, which is certainly clinically meaningful, but also for the first time, we have documented patients reporting that they are experiencing improved quality of life. This degree of early clinical benefit is extraordinarily rewarding to observe as a provider."

As of the data cut-off date of August 20, 2020, a total of 44 patients have been treated with LentiGlobin for SCD in the HGB-205 (n=3) and HGB-206 (n=41) clinical studies. The HGB-206 total includes: Groups A (n=7), B (n=2) and C (n=32).

HGB-206: Group C Updated Efficacy Results

The 32 patients treated with LentiGlobin for SCD gene therapy in Group C of HGB-206 had up to 30.9 months of follow-up (median of 13.0; min-max: 1.1 30.9 months).

In patients with six or more months of follow-up whose hemoglobin fractions were available (n=22), median levels of gene therapy-derived anti-sickling hemoglobin, HbAT87Q, were maintained with HbAT87Q contributing at least 40% of total hemoglobin at Month 6. At last visit reported, total hemoglobin ranged from 9.6 15.1 g/dL and HbAT87Q levels ranged from 2.7 8.9 g/dL. At Month 6, the production of HbAT87Q was associated with a reduction in the proportion of HbS in total hemoglobin; median HbS was 50% and remained less than 60% at all follow-up timepoints. All patients in Group C were able to stop regular blood transfusions by three months post-treatment and remain off transfusions as of the data cut-off.

Nineteen patients treated in Group C had a history of severe VOEs, defined as at least four severe VOEs in the 24 months prior to informed consent (annualized rate of severe VOE min-max: 2.0 10.5 events) and at least six months follow-up after treatment with LentiGlobin for SCD. There have been no reports of severe VOEs in these Group C patients following treatment with LentiGlobin for SCD. In addition, all 19 patients had a complete resolution of VOEs after Month 6.

In SCD, red blood cells become sickled and fragile, rupturing more easily than healthy red blood cells. The breakdown of red blood cells, called hemolysis, occurs normally in the body. However, in sickle cell disease, hemolysis happens too quickly due to the fragility of the red blood cells, which results in hemolytic anemia.

Patients treated with LentiGlobin for SCD in Group C demonstrated near-normal levels in key markers of hemolysis, which are indicators of the health of red blood cells. Lab results assessing these indicators were available for the majority of the 25 patients with 6 months of follow-up.

The medians for reticulocyte counts (n=23), lactate dehydrogenase (LDH) levels (n=21) and total bilirubin (n=24) continued to improve compared to screening values and stabilized by Month 6. In patients with Month 24 data (n=7), these values approached the upper limit of normal by Month 24. These results continue to suggest that treatment with LentiGlobin for SCD may improve biological markers to near-normal levels for SCD.

Pancellularity

As previously reported, assays were developed by bluebird bio to enable the detection of HbAT87Q and HbS protein in individual red blood cells, as well as to assess if HbAT87Q was pancellular, or present throughout all of a patients red blood cells. In 25 patients with at least six months of follow-up, on average, more than 80% of red blood cells contained HbAT87Q, suggesting near-complete pancellularity of HbAT87Q distribution and with pancellularity further increasing over time.

HGB-206: Improvements in Health-Related Quality of Life

Health-related quality of life (HRQoL) findings in Group C patients treated with LentiGlobin for SCD in the HGB-206 study were generated using the Patient Reported Outcomes Measurement Information System 57 (PROMIS-57), a validated instrument in SCD.

Data assessing pain intensity experienced by nine Group C patients were analyzed according to baseline pain intensity scores relative to the general population normative value: 2.6 on a scale of 0-10, where 10 equals the most intense pain. Data were assessed at baseline, Month 6 and Month 12.

Of the five patients with baseline scores worse than the population normative value average, four demonstrated clinically meaningful reductions in pain intensity at Month 12; the group had a mean score of 6.0 at baseline and a mean score of 2.4 at Month 12. Of the four patients with better than or near population normative values at baseline, two reported improvement and two remained stable with a mean score of 2.3 at baseline and 0.8 at Month 12.

HGB-206: Group C Safety Results

As of August 20, 2020, the safety data from Group C patients in HGB-206 remain generally consistent with the known side effects of hematopoietic stem cell collection and myeloablative single-agent busulfan conditioning, as well as underlying SCD. One non-serious, Grade 2 adverse event (AE) of febrile neutropenia was considered related to LentiGlobin for SCD. There were no serious AEs related to LentiGlobin for SCD.

One patient with significant baseline SCD-related and cardiopulmonary disease died 20 months post-treatment; the treating physician and an independent monitoring committee agreed his death was unlikely related to LentiGlobin for SCD and that SCD-related cardiac and pulmonary disease contributed.

Gene Therapy Global Market Insights, Analysis and Forecasts, 2015-2019 & 2020-2025 - Lentivirus, Non-viral Plasmid Vector, AAV, Retrovirus &...

View Supplement

The global viral vectors and plasmid DNA manufacturing market was valued at $319.01 million in 2019 and is expected to reach over $1.3 billion by 2027, according to a report from Precedence Research, which points out that viral vectors have become ideal for gene transfer due to their efficient gene delivery, high transfection efficiency, and stable gene expression. Further, an upsurge in the registration of clinical trials on viral vectormediated gene therapy is stimulating demand for viral vectors in gene transfer.

The growing pervasiveness of target disorders and diseases, the accessibility of funding for gene therapy development, current research into viral vectorbased cell and gene therapies, and efficacy of viral vectors in gene therapy delivery are together supporting the marketgrowth, notes the Precedence Research study.

The adeno associated virus (AAV) vector is the platform of choice for delivering gene therapeutics. But, as Nice Insight reports, the biggest challenges facing gene therapy lie in the areas of process development, manufacturing, and analytical technologies.

To address these issues we put together this special supplement entitled Navigating the Complexities of AAV Scale-Up and Manufacturing. Inside you will find ideas and advice on choosing the right starting material, ensuring the right scalable platform technology for maximizing titer, optimizing the AAV downstream purification process, and carrying out approved product process, characterization and QC testing for lot release. Leading gene therapy scientists in academia and experts in industry have been interviewed for critical insights on these topics. They will also give their thoughts on the future of the gene therapy industry, its trajectory over the next 5 to 10 years and the technologies that will accelerate further development of this field.

Dublin, Dec. 08, 2020 (GLOBE NEWSWIRE) -- The "Gene Therapy Global Market Report 2020-30: COVID-19 Growth and Change" report has been added to ResearchAndMarkets.com's offering.

Gene Therapy Global Market Report 2020-30: COVID-19 Growth and Change provides the strategists, marketers and senior management with the critical information they need to assess the global gene therapy market market.

Major players in the gene therapy market are Novartis AG, Bluebird Bio, Inc., Spark Therapeutics, Inc., Audentes Therapeutics, Voyager Therapeutics, Applied Genetic Technologies Corporation, UniQure N.V., Celgene Corporation, Cellectis S.A. and Sangamo Therapeutics.

The global gene therapy market is expected to decline from $3.22 billion in 2019 to $3.18 billion in 2020 at a compound annual growth rate (CAGR) of -1.30%. The decline is mainly due to the COVID-19 outbreak that has led to restrictive containment measures involving social distancing, remote working, and the closure of industries and other commercial activities resulting in operational challenges. The market is then expected to recover and reach $6.84 billion in 2023 at a CAGR of 29.09%.

The gene therapy market consists of sales of gene therapy related services by entities (organizations, sole traders and partnerships) that manufacture gene therapy drugs. Gene therapy is used to replace faulty genes or add new genes to cure disease or improve the body's ability to fight disease. Only goods and services traded between entities or sold to end consumers are included.

North America was the largest region in the gene therapy market in 2019.

The gene therapy market covered in this report is segmented by gene type into antigen; cytokine; suicide gene; others. It is also segmented by vector into viral vector; non-viral vector; others, by application into oncological disorders; rare diseases; cardiovascular diseases; neurological disorders; infectious diseases; others, and by end users into hospitals; homecare; specialty clinics; others.

In December 2019, Roche, a Switzerland-based company, completed its acquisition of Spark Therapeutics for $4.3 billion. With this deal, Roche is expected to strengthen its presence in the gene therapy segment, support transformational therapies and increase its product portfolio. Spark Therapeutics is a US-based company involved in gene therapy.

The high prices of gene therapy medicines are expected to limit the growth of the gene therapy market. The pressure to contain costs and demonstrate value is widespread. Political uncertainty and persistent economic stress in numerous countries are calling into question the sustainability of public health care funding. In less wealthy countries, the lack of cost-effective therapies for cancer and other diseases has influenced the health conditions of the population and has led to a low average life expectancy.

Luxturna, a one-time treatment for acquired retinal eye disease, costs $850,000 in the US and 613,410 in the UK, despite a markdown that is applied through Britain's National Health Service. Zolgensma, for spinal muscular atrophy, is valued at $2.1 million in the US and Zynteglo, which focuses on a rare genetic blood disorder, costs $1.78 million, thus restraining the growth of the market.

The use of machine learning and artificial intelligence is gradually gaining popularity in the gene therapy market. Artificial intelligence (AI) is the simulation of human intelligence in machines, which are programmed to display their natural intelligence. Machine learning is a part of AI.

Machine learning and AI help companies in the gene therapy market to conduct a detailed analysis of all relevant data, provide insights between tumor and immune cell interactions, and offer a more accurate evaluation of tissue samples often conflicted between different evaluators. For instance, since January 2020, GlaxoSmithKline, a pharmaceutical company, has been investing in AI to optimize gene therapy and develop off-the-shelf solutions for patients. It is also expected to reduce turnaround time and also the cost of gene therapies.

Global Gene Therapy Market Report 2020: Market is Expected to Recover and Reach $6.84 Billion in 2023 - Forecast to 2030 - GlobeNewswire

Older, male patients with more severe underlying conditions and a greater risk of death tended to be more accepting of new approaches such as stem cell research

A new review of research bringing together patient, carer and public views of cell and gene therapies has highlighted a need for appropriate education to better inform people including how clinical trials work and the risks and benefits of various treatments.

Over the last decade, new cell, gene and tissue-engineered therapies have been developed to treat various cancers, inherited diseases and some chronic conditions. They offer opportunities for the treatment of disease and injury, to restore function, and in some cases offer cures. In response the NHS Advanced Therapies Treatment Centres (ATTCs) were set up to bring together the health service, academia and industry to address the unique and complex challenges of bringing these therapies to patients.

Led by experts from the Centre for Patient Reported Outcome Research (CPROR) at the University of Birmingham and the Midlands and Wales ATTC (MW-ATTC), the review, funded by a MW-ATTC grant from UK Research and Innovation is the first of its kind and the first to consider both patient and public opinions of cell and gene therapies. Examining 35 studies, the majority of which were published between 2015 and 2020, analysis showed that a lack of understanding of the aims of clinical trials and overestimation of the potential benefits of cell and gene therapy were common among both patients and the general public. Patients were generally of the opinion that more information about participating in clinical trials is vital to enable them to make informed assessment of potential risks and benefits.

Older, male patients with more severe underlying conditions and a greater risk of death tended to be more accepting of new approaches such as stem cell research and generally, while views of therapies varied among patients, the provision of adequate information increased acceptance.

Interestingly the review also found that patients considered their clinicians to be the most trustworthy source of information which would suggest that patients would approach and discuss these treatments with their physicians. However, researchers found that this might not always be the case due to a number of reasons including the perception that clinicians do not always approve of cell and gene therapies and may try to discourage them from pursuing treatment and may not have enough knowledge of the field to provide adequate advice.

Lead author Dr Olalekan Lee Aiyegbusi, Co-Deputy Director of the Centre for Patient Reported Outcomes Research (CPROR) said: The findings from this research are intended to inform the patient engagement work of the ATTCs. We hope that by highlighting various issues, efforts will be made to correct misconceptions, and improve the awareness of patients and the public about the potential benefits and risks associated with cell and gene therapies.

It is important that the public and patients are aware of these therapies, understand the issues involved, and can contribute to the ongoing debates. A high level of awareness will also enhance patients ability to make informed decisions about participating in clinical trials and routine administration of cell and gene therapies.

The full paper Patient and public perspectives on cell and gene therapies: a systematic review was published today (Tuesday 8 December 2020) in Nature Communications.

NEW YORK, Dec. 11, 2020 (GLOBE NEWSWIRE) -- Prevail Therapeutics Inc. (Nasdaq: PRVL), a biotechnology company developing potentially disease-modifying AAV-based gene therapies for patients with neurodegenerative diseases, today announced that the first patient has been dosed in the Phase 1/2 PROCLAIM clinical trial evaluating PR006, an investigational AAV9 gene therapy delivering the GRN gene, for the treatment of frontotemporal dementia patients with GRN mutations (FTD-GRN).

Dosing the first patient in our PROCLAIM clinical trial marks an important milestone in our efforts to advance a potentially disease-modifying treatment for patients with frontotemporal dementia with GRN mutations, said Asa Abeliovich, M.D., Ph.D., Founder and Chief Executive Officer of Prevail. We are excited to progress clinical development of PR006 and to bring forward a much-needed therapy for this rapidly progressing neurodegenerative disease.

The PROCLAIM trial is a Phase 1/2 open-label trial investigating the safety and tolerability of PR006 as well as key biomarkers and exploratory efficacy endpoints. The Company expects to enroll up to 15 patients, and it currently anticipates it will provide a biomarker and safety analysis on a subset of patients enrolled in the PROCLAIM trial in 2021.

Frontotemporal dementia is a devastating condition, with no disease-modifying therapeutic options available, said Dr. JonathanRohrer, principal research fellow at theUniversity College London Queen Square Institute of Neurology.PROCLAIM is an important clinical study which could further increase our understanding of frontotemporal dementia due tomutations in the progranulin gene, and help demonstrate the potential of gene therapy to correct the underlying genetic cause of this condition, potentially slowing or stopping disease progression.

PR006 has been granted Orphan Drug designation for the treatment of FTD and Fast Track designation for the treatment of FTD-GRN by the U.S. Food and Drug Administration, as well as orphan designation for the treatment of FTD by the European Commission.

About Frontotemporal Dementia withGRNMutationsFrontotemporal dementia (FTD) is the second most common cause of dementia in people under the age of 65, after Alzheimers disease. FTD affects 50,000 to 60,000 people in the U.S. and 80,000 to 110,000 individuals in the European Union. FTD-GRN represents 5-10% of all patients with FTD. FTD results from the progressive degeneration of the frontal and temporal lobes of the brain, which control decision-making, behavior, emotion and language. In FTD-GRN patients, reduced levels of progranulin lead to age-dependent lysosomal dysfunction, neuroinflammation and neurodegeneration. There are no approved treatments for FTD or FTD-GRN.

About Prevail TherapeuticsPrevail is a gene therapy company leveraging breakthroughs in human genetics with the goal of developing and commercializing disease-modifying AAV-based gene therapies for patients with neurodegenerative diseases. The Company is developing PR001 for patients with Parkinsons disease with GBA1mutations (PD-GBA) and neuronopathic Gaucher disease (nGD); PR006 for patients with frontotemporal dementia withGRNmutations (FTD-GRN); and PR004 for patients with certain synucleinopathies.

Prevail was founded by Dr.Asa Abeliovichin 2017, through a collaborative effort withThe Silverstein Foundationfor Parkinsons with GBA and OrbiMed, and is headquartered inNewYork, NY.

Forward-Looking Statements Related to PrevailStatements contained in this press release regarding matters that are not historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended.

Using an experimental gene therapy, Harvard scientists have successfully restored vision to mice suffering glaucoma by effectively rewinding the aging process in their cells. While still in the early stages, the team says the research is a proof of concept for slowing the symptoms of aging with epigenetics.

To turn back the clock, the researchers delivered three key genes into the retinas of several groups of mice with different eye problems. In mice with optic nerve injuries, the treatment helped the nerves regenerate. The therapy also helped reverse vision loss in mice with a condition similar to glaucoma, as well as those with more general age-related impairment.

Our study demonstrates that its possible to safely reverse the age of complex tissues such as the retina and restore its youthful biological function, says David Sinclair, senior author of the study. If affirmed through further studies, these findings could be transformative for the care of age-related vision diseases like glaucoma and to the fields of biology and medical therapeutics for disease at large.

The team's research involves targeting the epigenome. The contents of our DNA isnt the only way information is passed down through generations the field of epigenetics explores how the expression of genes is turned on and off. One of the main epigenetic changes is DNA methylation, where patterns of molecules tag genes to control how theyre expressed without changing the underlying DNA sequence.

These methylation patterns are laid down during embryonic development, essentially helping different cell types only read the DNA sequences that are relevant to them. DNA methylation patterns are thought to become somewhat scrambled as we age, which changes gene expression and, in turn, impairs the function of cells. Ultimately, that results in the symptoms of aging that we all know too well.

So, the researchers on the new study set out to investigate whether restoring these patterns to a more youthful state could reverse damage to cells. They loaded three specific genes into a viral vehicle and introduced the package to the retinas of mice.

The genes in question Oct4, Sox2 and Klf4 are three of the four Yamanaka factors, a group of genes that are used to turn cells into induced pluriopotent stem cells, ready to become whatever cells are needed.

By only using three of the factors, the team didnt rewind the clock right back to the stem cell stage just far enough to return the cells to a healthier, more youthful state. Plus, it prevents the method from inducing tumor growth, which is a known pitfall.

And the treatment had promising results in the animal tests. In the mice with optic nerve damage, the treatment doubled the number of surviving retinal ganglion cells, and regrew the nerves five times better than the control.

Yuancheng Lu

In those with glaucoma or age-related vision loss, gene expression patterns and electrical signals in optic nerve cells increased to levels normally seen in young, healthy mice. The animals also performed better in visual acuity tests.

Regaining visual function after the injury occurred has rarely been demonstrated by scientists, says Meredith Gregory-Ksander, an author of the study. This new approach, which successfully reverses multiple causes of vision loss in mice without the need for a retinal transplant, represents a new treatment modality in regenerative medicine.

The team says that if the findings can be validated in further animal studies, human clinical trials could begin in glaucoma patients within two years.

The research was published in the journal Nature.

Janssen is tapping little-known and privately held Hemera Biosciences for a new gene therapy aimed at reversing a severe disease.

The deal, financials of which are not being shared, is for the investigational phase 1 gene therapy HMR59, which is given as a one-and-done shot into the eye with the aim of helping preserve vision in patients with geographic atrophy, a late-stage and severe form of age-related macular degeneration (AMD).

Accelerate Biologics, Gene and Cell Therapy Product Development partnering with GenScript ProBio

GenScript ProBio is the bio-pharmaceutical CDMO segment of the worlds leading biotech company GenScript, proactively providing end-to-end service from drug discovery to commercialization with professional solutions and efficient processes to accelerate drug development for customers.

Patients with AMD often have low levels of CD59, a protein that protects the retina from damage caused by an essential part of the body's natural immune response called complement. In geographic atrophy, which affects around 5 million people globally, an overactivity of complement destroys cells in the macula, the central part of the retina.

HMR59 is designed to increase the ability of retina cells to make a soluble form of CD59, with the theory being it can help stop further damage and retain a patients vision. It has already passed a phase 1 test, with a second in patients with wet AMD currently conducting follow-up visits to evaluate long-term safety, according to a statement.

There are currently no medical treatments that can regenerate retinal cells that have atrophied, though gene therapies and stem cell therapies are the leading R&D hopes in this field.

Geographic atrophy is a devastating form of AMD that impacts the ability to accomplish everyday tasks, such as reading, driving, cooking, or even seeing faces, said James List, M.D., Ph.D., global therapeutic area head, cardiovascular and metabolism, Janssen R&D.

Our aim with this novel, single-administration gene therapy is to use our development expertise and deep heritage in vision care to help improve patient outcomes by intervening early, halting the progression to blindness, and preserving more years of sight.

Janssen will hope to have the success seen from gene therapy Luxturna, a drug from Novartis and Spark Therapeutics for retinal degeneration caused by mutations in the gene RPE65, after the product was approved in 2017, and helped Spark into a Roche buyout in 2019.

Other companies are also on the hunt, such as the recent tie-up between Biogen and Harvard University's Massachusetts Eye and Ear thats aimed at developing a gene therapy to help some patients with these blinding diseases.

The gene at the center of the new agreement, PRPF31, has been linked to autosomal dominant retinitis pigmentosa. Several other gene therapies are being developed to treat retinitis pigmentosa. They include Allergans RST-001, which the company picked up when it acquired RetroSense Therapeutics for $60 million in 2016.

Iveric Bio is also working on a geographic atrophy therapy, known as Zimura (avacincaptad pegol), with it posting clinically meaningful late-stage follow-up data this summer for the complement C5 inhibitor.

Gene therapy pioneer Jim Wilson and the University of Pennsylvania are teaming up with Regeneron to help deliver its COVID-19 antibody cocktail using adeno-associated virus (AAV) tech in the hope of curbing infection via a nasal spray.

The antibody cocktail, made up of casirivimab and imdevimab, was given a speedy authorization by the FDA less than two weeks ago as a treatment for certain COVID-19 patients. But, keeping up with the fast pace of SARS-CoV-02 R&D, Regeneron is not resting on its laurels and now wants to find a quicker way of delivering its therapy while also working on it as a prophylactic.

These antibodies are currently injected into patients, but Regeneron and Penn will use Wilsons gene therapy know-how to attempt a nasal spray formulation using AAV vectors. The belief is that this could prevent infection with the virus using a technology typically used in high-tech gene therapies.

The group plans to study the safety and effectiveness of using AAV vectors to introduce the sequence of the cocktails virus-neutralizing antibodies directly to nasal epithelial cells and see whether it can help protect against the disease.

The first step is to finish preclinical trials; if successful, an IND will be sent off to the FDA for human trials.

Wilsons team said it was hopeful that introducing the therapy via single dose of AAV will be able to produce similar protection Regeneron has seen for its cocktail, but for potentially a longer duration.

Regeneron scientists specifically selected casirivimab and imdevimab to block infectivity of SARS-CoV-2, the virus that causes COVID-19, and we have been encouraged by the promising clinical data thus far, said Christos Kyratsous, Ph.D., vice president of research, infectious diseases and viral vector technologies at Regeneron.

In the quest to use cutting-edge science to help end this disruptive and often very devastating disease, we are excited to explore alternate delivery mechanisms such as AAV that may extend the potential benefits of this investigational therapy to even more people around the world.

Bayer has created a cell and gene therapy platform to support its growing pipeline of advanced therapy medicinal products. The platform is intended to enable Bayer to make its expertise and resources available to its partners while preserving their autonomy and culture.

Germanys Bayer has moved into cell and gene therapies on multiple fronts in recent years, buying up induced pluripotent stem cell specialist BlueRock Therapeutics and adeno-associated virus (AAV) gene therapy player Asklepios BioPharmaceutical while investing in a clutch of other biotechs. The deals have given Bayer a pipeline of five advanced assets and more than 15 preclinical prospects.

Accelerate Biologics, Gene and Cell Therapy Product Development partnering with GenScript ProBio

GenScript ProBio is the bio-pharmaceutical CDMO segment of the worlds leading biotech company GenScript, proactively providing end-to-end service from drug discovery to commercialization with professional solutions and efficient processes to accelerate drug development for customers.

Rather than subsume BlueRock and AskBio, Bayer opted to allow the businesses to operate as independent companies in an attempt to preserve their cultures. Yet, Bayer also wants to enable the companies to realize the benefits that can come from being part of a larger organization.

The cell and gene therapy platform is the result of that effort to get the best of both worlds. Bayer will use the platform to provide support to its cell and gene therapy businesses and orchestrate its operations in the area across the product life cycle. Specific areas of support offered by the platform span preclinical through to commercial, strategy implementation and project management.

Bayer is investing in its internal capabilities to strengthen the platform as well as looking to enter into strategic collaborations, acquire technologies and strike licensing deals. The deals entered into so far have given Bayer infrastructure as well as product candidates.

Notably, AskBio has a CDMO unit, Viralgen, specializing in AAV gene therapy production. As limited access to manufacturing capacity has been a barrier to speedy gene therapy development, buying the CDMO could help Bayer remove a constraint on the progress of its programs and become a more attractive partner for startups. Bayer thinks allowing acquired startups autonomy makes it attractive, too.

Wolfram Carius, who joined Bayer from Sanofi in 2016, is heading up the new cell and gene therapy platform. Carius said the platform is vital to accelerate innovation at its source, and to ensure its translation into tangible therapies for patients who have no time to wait in a statement.

Bayers platform is a twist on strategies being pursued by many of its peers, which have identified cell and gene therapies as growth areas and bought in assets but sought to avoid smothering the startups. Kite, for example, operates as its own business unit within Gilead Sciences, and Spark Therapeutics is an independent company within the Roche group.

Nadofaragene firadenovec, a novel intravesical therapy for nonmuscle-invasive bladder cancer (NMIBC) that does not respond to bacillus Calmette- Gurin (BCG) therapy shows efficacy across important patient subgroups, investigators reported at SUO 2020, the virtual annual meeting of the Society of Urologic Oncology.

In the original phase 3 trial of 157 patients with high-grade BCG-unresponsive NMIBC, clinicians delivered nadofaragene firadenovec (also known as rAd-IFNa/Syn3), a non-replicating adenovirus vector-based gene therapy containing the gene interferon alfa-2b, by catheter into the bladder epithelium once every 3 months. The 3-month complete response rate was 59.6% overall and 53.4% in patients with carcinoma in situ (CIS) with or without Ta or T1 tumors. In addition, 72.9% of patients with high-grade Ta or T1 tumors and no CIS had freedom from high-grade recurrence. At 12 months, 30.5% overall, 24.3% of patients with CIS (with or without Ta or T1 tumors), and 43.8% of patients with high-grade Ta or T1 tumors (and no CIS) were free from high-grade recurrence.

For both the CIS and high-grade Ta/T1 only cohorts, there were no significant differences in response rates at 3 and 15 months between male and female patients, patients younger and older than 70 years, BCG-refractory vs BCG-relapsed disease, patients with more or less than 3 prior lines of therapy, number of prior non-BCG regimens, and patients with more or less than 3 prior courses of BCG, Vikram Narayan, MD, of Emory University in Atlanta, Georgia, reported.

Duration of response also did not differ significantly among groups, Dr Narayan reported. Only in the CIS cohort, patients who received 3 or fewer prior courses of BCG had significantly longer duration of response compared with patients who received more than 3 courses: 12.68 vs 4.96 months. A multivariable analysis confirmed that none of these baseline characteristics or prior therapy significantly influenced response rates at 3 and 15 months or duration of response.

These results demonstrate the efficacy of nadofaragene firadenovec regardless of patient characteristics or prior treatment history, Dr Narayan stated. Nadofaragene firadenovec represents a potential novel treatment option for patients with high-grade BCG-unresponsive NMIBC that advances the current treatment paradigm.

The FDA is currently reviewing a biologics license application (BLA) for nadofaragene firadenovec.
