Fact Check-mRNA vaccines are distinct from gene therapy … – Reuters
Posted: October 29, 2022 at 2:38 am
Vaccines that use mRNA technology are not gene therapy because they do not alter your genes, experts have told Reuters after contrary claims were posted online.
Thousands of social media users have shared such posts since the rollout of COVID-19 vaccines began (here) and have continued to do so through August.
Its not a vaccine. Its gene therapy! wrote one Facebook user on Aug. 9, noting that gene therapy manipulates genetic code (here and here).
Pfizer/BioNTech and Moderna have both developed shots that use a piece of genetic code from SARS-CoV-2, the coronavirus that causes COVID-19, to prompt an immune response in recipients (here). However, experts told Reuters that this is not the same as gene therapy.
As mRNA is genetic material, mRNA vaccines can be looked at as a genetic-based therapy, but they are classified as vaccines and are not designed to alter your genes, said Dr Adam Taylor, a virologist and research fellow at the Menzies Health Institute, Queensland, Griffith University.
Gene therapy, in the classical sense, involves making deliberate changes to a patients DNA in order to treat or cure them. mRNA vaccines will not enter a cells nucleus that houses your DNA genome. There is zero risk of these vaccines integrating into our own genome or altering our genetic makeup.
Taylor explained that mRNA enters cells shortly after vaccination and instructs them to create a SARS-CoV-2 spike protein, prompting the immune response.
He added that unlike gene therapy, mRNA vaccines are then rapidly degraded by the body.
In fact, because mRNA is degraded so quickly chemical modifications can be made to mRNA vaccines to make them a little more stable than regular mRNA.
Gene therapy, on the other hand, involves a process whereby an individuals genetic makeup is deliberately modified to cure or treat a specific genetic condition (here).
It can be done in several ways, such as replacing a disease-causing gene with a healthy alternative, disabling a disease-causing gene or introducing a new gene to help treat a disease, according to the U.S. Food and Drug Administration (FDA) (here).
If we suffer from an inherited blood disease then the defect in our genes can be corrected in blood cells and then we can be cured, said David Schaffer, professor of Chemical and Biomolecular Engineering and Director of the Berkeley Stem Cell Center at the University of California, Berkeley, in an email to Reuters.
In most cases, the DNA is therapeutic because it encodes a mRNA, which encodes a protein that has a beneficial effect on a patient. So, if someone has a disease where the gene encoding an important protein is mutated - such as hemophilia, cystic fibrosis, retinitis pigments - then it can be possible to deliver the DNA encoding the correct copy of that protein in order to treat the disease.
He added: Because DNA has the potential to persist in the cells of a patient for years, this raises the possibility of a single gene therapy treatment resulting in years of therapeutic benefit.
Moderna, which has developed one of the mRNA COVID-19 vaccines used across the world, explained in a fact sheet that mRNA and gene therapy take fundamentally different approaches.
Gene therapy and gene editing alter the original genetic information each cell carries, the company writes. The goal is to produce a permanent fix to the underlying genetic problem by changing the defective gene. Moderna is taking a different approach to address the underlying cause of MMA and other diseases. mRNA transfers the instructions stored in DNA to make the proteins required in every living cell. Our approach aims to help the body make its own missing or defective protein (www.modernatx.com/about-mrna).
Reuters has in the past debunked claims that COVID-19 vaccines can genetically modify humans here and here .
Missing context. Scientists told Reuters that while mRNA vaccines can be considered genetic-based therapy because they use genetic code from COVID-19, they are not technically gene therapy. This is because the mRNA does not change the bodys genetic makeup.

Gene therapy: The Potential for Treating Type 1 Diabetes – Healthline
Posted: October 13, 2022 at 2:06 am
Many people whove recently received a diagnosis of type 1 diabetes (T1D) immediately think, When will there be a cure?
While the potential for a cure has been dangling in front of people with T1D for what seems like forever, more researchers currently believe that gene therapy could finally one day soon, even be the so-called cure thats been so elusive.
This article will explain what gene therapy is, how its similar to gene editing, and how gene therapy could potentially be the cure for T1D, helping millions of people around the world.
Gene therapy is a medical field of study that focuses on the genetic modification of human cells to treat or sometimes even cure a particular disease. This happens by reconstructing or repairing defective or damaged genetic material in your body.
This advanced technology is only in the early research phases of clinical trials for treating diabetes in the United States. Yet, it has the potential to treat and cure a wide range of other conditions beyond just T1D, including AIDS, cancer, cystic fibrosis (a disorder that damages your lungs, digestive tract, and other organs), heart disease, and hemophilia (a disorder in which your blood has trouble clotting).
For T1D, gene therapy could look like the reprogramming of alternative cells, making those reprogrammed cells perform the functions your original insulin-producing beta cells would otherwise perform. If you have with diabetes, that includes producing insulin.
But the reprogrammed cells would be different enough from beta cells so that your own immune system wouldnt recognize them as new cells and attack them, which is what happens in the development of T1D.
While gene therapy is still in its infancy and available only in clinical trials, the evidence so far is becoming clearer about the potential benefits of this treatment.
In a 2018 study, researchers engineered alpha cells to function just like beta cells. They created an adeno-associated viral (AAV) vector to deliver two proteins, pancreatic and duodenal homeobox 1 and MAF basic leucine zipper transcription factor A, to a mouses pancreas. These two proteins help with beta cell proliferation, maturation, and function.
Alpha cells are the ideal type of cell to transform into beta-like cells because not only are they also located within the pancreas, but theyre abundant in your body and similar enough to beta cells that the transformation is possible. Beta cells produce insulin to lower your blood sugar levels while alpha cells produce glucagon, which increases your blood sugar levels.
In the study, mouse blood sugar levels were normal for 4 months with gene therapy, all without immunosuppressant drugs, which inhibit or prevent the activity of your immune system. The newly created alpha cells, performing just like beta cells, were resistant to the bodys immune attacks.
But the normal glucose levels observed in the mice werent permanent. This could potentially translate into several years of normal glucose levels in humans rather than a longtime cure.
In this Wisconsin study from 2013 (updated as of 2017), researchers found that when a small sequence of DNA was injected into the veins of rats with diabetes, it created insulin-producing cells that normalized blood glucose levels for up to 6 weeks. That was all from a single injection.
This is a landmark clinical trial, as it was the first research study to validate a DNA-based insulin gene therapy that could potentially one day treat T1D in humans.
This was how the study worked:
The researchers are now working on increasing the time interval between therapy DNA injections from 6 weeks to 6 months to provide more relief for people with T1D in the future.
While this is all very exciting, more research is needed to determine how practical the therapy is for people. Eventually, the hope is that the AAV vectors could eventually be delivered to the pancreas through a nonsurgical, endoscopic procedure, in which a doctor uses a medical device with a light attached to look inside your body.
These kinds of gene therapy wouldnt be a one-and-done cure. But it would provide a lot of relief to people with diabetes to perhaps enjoy several years of nondiabetes glucose numbers without taking insulin.
If subsequent trials in other nonhuman primates are successful, human trials may soon begin for the T1D treatment.
Does that count as a cure?
It all depends on who you ask because the definition of a cure for T1D varies.
Some people believe that a cure is a one-and-done endeavor. They see a cure as meaning youd never have to think about taking insulin, checking blood sugars, or the highs and lows of diabetes ever again. This even means you wouldnt have to ever go back to a hospital for a gene therapy follow-up treatment.
Other people think that a once-in-a-few-years treatment of gene editing may be enough of a therapy plan to count as a cure.
Many others believe that you need to fix the underlying autoimmune response to truly be cured, and some people dont really care one way or another, as long as their blood sugars are normal, and the mental tax of diabetes is relieved.
One potential one-and-done therapy could be gene editing, which is slightly different from gene therapy.
The idea behind gene editing is to reprogram your bodys DNA, and if you have type 1 diabetes, the idea is to get at the underlying cause of the autoimmune attack that destroyed your beta cells and caused T1D to begin with.
Two well-known companies, CRISPR Therapeutics and regenerative med-tech company ViaCyte, have been collaborating for a few years to use gene editing to create islet cells, encapsulate them, and then implant them into your body. These protected, transplanted islet cells would be safe from an immune system attack, which would otherwise be the typical response if you have T1D.
The focus of gene editing is to simply cut out the bad parts of our DNA in order to avoid conditions such as diabetes altogether and to stop the continuous immune response (beta cell attack) that people who already have diabetes experience daily (without their conscious awareness).
The gene editing done by CRISPR in their partnership with ViaCyte is creating insulin-producing islet cells that can evade an autoimmune response. These technology and research are ever evolving and hold a lot of promise.
Additionally, a 2017 study shows that a T1Dcure may one day be possible by using gene-editing technology.
Both gene therapy and gene editing hold a lot of promise for people living with T1D who are hoping for an eventual future without needing to take insulin or immunosuppressant therapy.
Gene therapy research continues, looking at how certain cells in the body could be reprogrammed to start making insulin and not experience an immune system response, such as those who develop T1D.
While gene therapy and gene-editing therapy are still in their early stages (and much has been held up by the coronavirus disease 19 [COVID-19] pandemic), theres a lot of hope for a T1D cure in our near future.

Gene Therapy Hits Its Stride in the Clinic – Genetic Engineering & Biotechnology News
Posted: October 13, 2022 at 2:06 am
Gene therapy has a history of presenting possibilities that stay out of reach for a long time. The tantalizing idea of using exogenous good DNA to replace defective DNA was suggested by Stanfield Rogers in 1970. Then, in 1972, the idea was elaborated upon by Theodore Friedmann and Richard Roblin, who wrote that viruses could be tweaked to contain human genes and allowed to infect patients. Once copied into patients cells, the genes could start to function, compensating for defective and disease-causing genes.1
Despite these conceptual advances, clinical progress was slow. Indeed, there were dead ends and reversals. In 1971, Rogers deployed a naturally occurring virus in an attempt to treat an arginase deficiency. And in 1980, Martin J. Cline tried to treat b-thalassemia by using an ex vivo procedure in which bone marrow cells were transfected with a recombinant human globin gene and then reintroduced to patients. Both these efforts were, at best, inconclusive.
Finally, a partial and temporary gene therapy success was reported in 1990. Scientists led by William French Anderson used an ex vivo procedure to treat a four-year-old girl suffering adenosine deaminasedeficient severe combined immunodeficiency disease. They infected the patients own white blood cells with a virus that had been engineered to carry a gene encoding a functional variant of the adenosine deaminase gene. For two years, transfusions were administered that incorporated transfected white blood cells. The transfusions didnt bring about a cure, but they did help reduce the patients symptoms.
Then, in 1999, the field suffered a major setback when an 18-year-old patient with a metabolic disorder died after suffering an immune overreaction to an adenovirus designed to restore a missing liver enzyme. And a few years later, several patients with immunodeficiencies developed leukemias after receiving gene therapy, as the viruses caused insertions into cancer-related genome sites. The U.S. Food and Drug Administration (FDA) reacted swiftly, putting many gene trials on hold.2 The development of gene therapy stalled.
In subsequent years, however, researchers learned from these setbacks. For instance, safer viral vectors were identified, such as adeno-associated viruses (AAVs). The genes they deliver typically remain in the cell cytoplasm and are expressed there, rather than being integrated into human cells genomes, making them less likely than some earlier vectors to trigger cancer.
Since 2017, the FDA has approved several gene therapies for disorders caused by defects in single genes, including Luxturna for retinal dystrophy, Zolgensma for young children with spinal muscular atrophy, and Zynteglo for certain patients with b-thalassemia. The agency has also green-lighted several cell-based gene therapies which alter patients cells and reinfuse them into patients. For example, approvals have been granted to several therapies that use modified T cells, specifically, chimeric antigen receptor (CAR) T cells. They have proven effective in treating certain blood cancers.
Meanwhile, hundreds more gene therapy trials are underway. To get a sense of what these trials tell us about the current status and near-term future of gene therapy, GEN spoke with representatives of companies at various stages of clinical development. They took the opportunity to expand on the results they shared at the 25th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT), which was held last May in Washington, DC. They emphasized that for many diseaseshereditary monogenic disorders, complex diseases, and even cancersingle-dose gene therapies held disease-modifying potential.
The New York Citybased Lexeo Therapeutics has been developing a treatment for Friedreichs ataxia (FA), a rare condition that is currently incurable. Its caused by a mutation in the frataxin gene FXN which leads to progressive degeneration of the nervous system. Rather than targeting the diseases neurological pathology, which is tricky as the viruses fail to transduce efficiently and specifically in affected brain areas, Lexeo tackles the oft-fatal cardiac disease associated with FA, said Jay Barth, MD, Lexeos executive vice president and chief medical officer.
Lexeos therapeutic, LX2006, employs an AAV thats effective at infecting cardiac cells, introducing the FXN gene, increasing frataxin levels, and thereby restoring mitochondrial function. According to data presented at the ASGCT conference, mouse models of FA that received a single intravenous dose of LX2006 had improved heart function, general mobility, and survival compared with untreated rodents, even after they developed fairly advanced cardiac disease, Barth noted.3
Lexeo is planning a Phase I/II trial to assess safety of the therapy in 10 FA patients with cardiomyopathy. One of the goals is to identify the maximum safest dose for LX2006.4 Investigators are taking a cautious approach, Barth said, as overexpression of frataxin has been associated with safety issues.
The first study cohorts will receive the lowest dose thats shown efficacy in mice, and the dose will be incrementally increased in subsequent groups. Frataxin levels will be monitored through heart tissue biopsies. Patients will be followed for one year, and then for an additional four years as the FDA requires. In Barths view, the study could help find some way to prolong the lives of these patients beyond what the disease would give them.
While many gene therapy companies focus on restoring lost functions to normal cells, the Australia-based immuno-oncology company Imugene is employing the method to help kill cancer cells. In 2019, the company acquired an oncolytic virus called CF33, a chimeric vaccinia that infects and selectively replicates in malignant solid tumor cells.5
Imugene scientists have tinkered with CF33 in various ways that are already being tested in patients with specific cancer types. But according to Leslie Chong, the companys chief executive officer and managing director, the crown jewel of Imugene is a version of CF33 that contains a gene encoding the CD19 protein.
This surface protein is expressed on B cells and is the target of several CAR T-cell therapies. Using CF33 to induce uniform expression of CD19 across tumor cells could make CAR T-cell therapy work against solid tumors, which has proven a challenge as the tumors often express a heterogeneous mix of cell surface antigens. But with CF33, Chong explained, We line all your solid tumor [cells] with the CD19-directed targets, such that when you add a CD19-targeted therapy, you then obliterate the solid tumor where it hasnt had markers before.
In 2020, scientists at the City of Hope National Medical Center published data in support of this approach.6 Specifically, the scientists used mouse models of various cancer types to study the effects of administering the CD19-carrying CF33 virus followed by CD19-directed CAR T-cell therapy. Mice that received the antigen-matched therapy survived significantly longer than mice that received only mock T cells or CD19-CAR T cells.
Imugene looks forward to identifying indications that may benefit the most from this onCARlytics approach. The company is also planning a human trial. In our initial in-clinic study, we will be focused on certain indications, Chong noted. However, I think the application could be huge.
The North Carolinabased gene therapy company Asklepios BioPharmaceutical (AskBio) is also pursuing a target that falls outside the usual paradigm of monogenic disorders: congestive heart failure (CHF), a chronic and progressive condition in which the heart cannot pump blood sufficiently. Theres a high unmet medical need to develop additional medicines to reduce mortality and improve quality of life for the patients, said Canwen Jiang, MD, PhD, AskBios chief development officer and chief medical officer.
AskBios approach to tackling this complex disease has been to deliver a gene encoding the phosphatase-1 inhibitor-1, a key protein in regulating cardiac contractions. Introducing the gene via an AAV thats engineered to target cardiac cells could improve heart function as well as reverse and prevent the detrimental remodeling of cardiac muscle that occurs in CHF, Jiang said. The therapy, NAN-101, is delivered via a one-time injection into the hearts coronary arteries.
After collecting robust preclinical data, AskBio launched a Phase I study in 2019, enrolling eight individuals with Class III CHF. According to preliminary results presented at the ASGCT meeting, investigators observed efficient transduction of NAN-101 in heart cells of one trial participant from whom a tissue biopsy could be obtained.7 A cohort consisting of three patients who had completed their 12-month follow-up appeared to tolerate the treatment well and saw consistent improvements in heart function.8
If successful, such studies will not only motivate AskBio to expand into broader CHF indications, but also bolster the idea that gene therapy is useful beyond monogenic disorders. It would be a confidence-building example for the industry, for the academic community, as well as for the regulatory agencies, Jiang said.
One of the companies at the Phase III stage is Sarepta Therapeutics, a Cambridge, MAbased biotech firm specializing in rare diseases such as Duchenne muscular dystrophy (DMD), a monogenic disease that causes progressive muscle deterioration.
The gene therapy SRP9001 is based on an AAV virus subtype with an affinity for reaching muscle cells. It contains a gene encoding a form of the dystrophin protein, which is lacking in DMD patients tissues, coupled with a promoter that causes selective expression in skeletal and cardiac muscle cells, explained Jake Elkins, MD, Sareptas senior vice president of research and development and chief medical officer.
In a pilot study that tracked four DMD patients aged four to seven, data was collected four to five years after SRP9001 was taken. The treatment was well tolerated, and patients showed a 7-point improvement on a 17-step mobility scale (the North Star Ambulatory Assessment), despite being at an age where theyd typically experience rapid deterioration of mobility.9 A randomized Phase II study of 41 pediatric participants has so far bolstered these observations at one year of follow up, Elkins noted.10
Currently, Sarepta is closely tracking 120 boys with DMD aged four to seven in a Phase III study. The first half of patients are receiving gene therapy in the first year, during which the second half will receive a placebo until being rolled onto gene therapy after one year. At one year, were able to document clinically meaningful effects of the therapy, Elkins said. We view it as a confirmatory study of our early findings, but [it] will really expand our knowledge base of how this treatment works across the range of ambulatory patients with DMD.
Ultragenyx Pharmaceutical, a California-based rare disease-focused company, has also reached the Phase III stage with DTX401, which tackles glycogen storage disease type IA (GSDIa). This condition is caused by a genetic deficiency of the enzyme glucose-6-phosphatase, which breaks down glycogen reserves into glucose during fasting periods. GSDIa causes low blood sugar and accumulation of glycogen in the liver and kidneys, and patients need to regularly take cornstarch to maintain normal blood sugar levels, explained Eric Crombez, MD, Ultragenyxs chief medical officer for gene therapy and inborn errors of metabolism.
DTX401 is based on a liver-targeting AAV designed to restore glucose-6-phosphatase expression in patients hepatocytes. According to results presented at the ASGCT meeting, a Phase I/II study of DTX401 reported only mild adverse events in adult GSDIa patients.11 And all 12 participants were able to reduce their daily cornstarch intake by around 70% over three years. When interviewed at 52 weeks, most of the patients reported having more energy and better mental clarity.
If the transgene wasnt working, they would be having a lot of problems, Crombez asserted. [We can see that] they dont, [which] shows that weve established the normal breakdown of glycogen to produce glucose.
Motivated by these results, the company launched a Phase III study in 50 patients to compare the efficacy of DTX401 to that of a saline infusion. Primary endpointsincluding patients ability to taper cornstarch usewill be assessed after 48 weeks, but investigators hope to follow patients for as long as possible.
As the liver has high cell turnover, and the therapy doesnt integrate into the genome, the transgene will eventually be lost, Crombez said. Thats why he doesnt describe gene therapy as a cure in the strictest sense. However, he emphasizes that even if you need [another] dose 20 years down the road, [youve still] treated it for a very long period of time.

The promised land of gene therapy: Commercialization of novel gene-editing technology in beta-thalassemia – PMLiVE
Posted: October 13, 2022 at 2:06 am
With transformative treatments that leverage CRISPR technology, there are many challenges to overcome throughout the journey of development through to patient access. We interviewed a researcher at a top 20 pharma company, multiple patients, and our own market access experts for their insights into the process, obstacles, and opportunities for biopharmaceutical companies to meet patient needs and achieve success in the market.
Gene therapies and research into them have grown immensely in recent years, offering more novel tools in regenerative medicine to fight disease, including rare diseases and genetic disorders. In the last decade, there has also been rapid development and interest in CRISPR/Cas9 technology and other gene-editing tools that could offer transformative avenues to deliver gene therapies for patients and families affected by devastating diseases such as sickle cell disease and thalassemia.
Beta-thalassemia is a rare blood disorder caused by a genetic defect in hemoglobin. Several manufacturers are developing novel treatments for the disease, including Vertex, which has partnered with CRISPR Therapeutics to develop a gene-editing treatment for beta-thalassemia and sickle cell. In October 2022, the companiesannounced their plan to file exagamglogene autotemcel, the CRISPR/Cas9- edited therapy, for a rolling review with the FDA. Novartis also recently inked an up-to$1.5 billion deal with Precision Biosciences to support its development of one-time treatments for beta-thalassemia and sickle cell. The move marks a continuation in its ongoing commitment to exploring gene-editing technology.
Despite the surge of interest from both scientific and financial stakeholders, there remain numerous unique challenges at every step of this new frontier. From developing and financing the therapy in a timely manner to market access challenges due to the lack of maturity and extensive evidence, and explaining the complex science to physicians and patients, there are a variety of hurdles to overcome before bringing this type of technology to market. And while regenerative and curative therapies are often greatly lauded, there are also challenges in treating affected patient populations, including cost, accessibility, side effects, and other associated risks.
Earlier this year, the US Food and Drug Administration (FDA)approved the first potentially curative gene therapy to treat beta-thalassemia. While multiple companies have been working to bring transformative technologies such as CRISPR to market, approval will require further consideration around the many concerns and challenges of each stakeholder at every step. From the research and development stage all the way to patient access and treatment, remaining considerate of the populations that will ultimately be the end-users and testament to the technologys success is vital.
Diagnosed with beta-thalassemia at six months old, Amar has had regular blood transfusions every few weeks for the majority of his life. As a child, he found himself falling behind others his age. I always felt I was playing catch-up, through school, work, lifealways making up for lost time, he says.
Now in his 40s, he reflects on both the physical and mental impacts of the disease. He says, As Im getting older, my body is deteriorating, and it raises concerns for my future and what my life expectancy will look like. The disease has triggered other health conditions, including osteoarthritis, hypogonadism, and diabetes. Its a constant challenge, both physically and mentally, he says.

FDA Expands Oversight of Cell and Gene Therapies – Pharmaceutical Technology Magazine

CBER maps modernization plan to handle surge in research and applications.
FDAs Center for Biologics Evaluation and Research (CBER) is updating how it manages a growing volume of cellular and gene therapy development programs, seeking added resources and revisions in its oversight of these cutting-edge therapies. Most visible in the elevation of CBERs Office of Tissues and Advanced Therapies (OTAT) into a new super Office of Therapeutic Products (OTP). The change aims to improve functional alignment, increase review capabilities, and add expertise on new cell and gene therapies by establishing multiple branches and divisions in the expanded regulatory unit, as announced in the Federal Register on Sept. 28, 2002.
Stated goals are to help CBER address the substantial growth in innovative, novel products that present new scientific, medical and regulatory challenges that require changes to its structure, including strategies to advance the Regenerative Medicine Advanced Therapy (RMAT) program. The added resources are needed to oversee more than 2000 development programs involving cellular and gene therapies, many involving innovative testing and manufacturing processes. This soaring workload has over-taxed CBER staffers, resulting in serious difficulties in retaining and hiring capable scientists.
The structural changes at CBER reflect agreed-on plans to hire new staffers with funding from recently reauthorized user fee programs. The PDUFA VII commitment letter calls for an additional 132 new hires for CBER in this coming year and another 48 employees the following year, most to support cell and gene therapy reviews at OTP. The reorganization plan calls for OTP to have seven officesfor therapeutic products, clinical evaluation, review management, pharmacology/toxicology, and two for CMCfor gene therapy and for cellular therapy and human tissues. There will be 14 divisions and 32 branches within those offices, providing attractive supervisory opportunities for both new and experienced staffers.
These changes come in the wake of FDA approval of two new gene therapies that have drawn wide attention for both their therapeutic potential and for million-dollar price tags. Bluebird bios Zynteglo was approved by FDA in August for patients with beta thalassemia, an inherited blood disorder causing serious anemia. That was followed a few weeks later with approval of Bluebirds Skysona to treat a rare neurological disorder afflicting young boys. Zynteglo carries a $2.8 million price tag, Skysonas list price is $4 million, but both therapies are expected to target fewer than 1500 patients, limiting the overall cost impact for the US healthcare system. A greater spending effect would come from FDA approval of a new treatment for sickle cell disease from Vertex Pharmaceuticals and CRISPR Therapeutics, which plan to begin a rolling review by FDA in the coming months. The important potential benefits of these treatments, along with concerns about their impact on healthcare spending and access, speaks to the need for a highly capable and sufficiently resourced FDA oversight program.
These developments also highlight the importance of sound testing and production methods for therapies made from living organisms, which are inherently variable and difficult to control and measure to assure product safety, identify, quality, purity, and strength. The surge in applications from a broad range of firms, moreover, has made it difficult for CBER staffers to schedule formal meetings with each sponsor seeking advice on how best to perform manufacturing and testing processes. And publishing new guidance on these changing and emerging issues also takes time and resources.
In response, FDA looks to engage a broad range of sponsors on topics related to product development through a series of virtual town hall meetings. The first was held Sept. 29, 2022 and addressed how manufacturers should describe and inform FDA about chemistry, manufacturing, and controls (CMC) in applications for gene therapies. Wilson Bryan, OTAT (now OTP) director, opened the session by describing plans for establishing OTP as a super office to increase review capabilities and enhance expertise on gene and cellular therapies and set the stage for OTP branch chiefs to field a broad range of queries, ranging from basic CMC policies for various stages of development, to the scope of potency assays and impact of delivery devices on dose potency and quality [a recording of the town hall meeting is available at the FDA events link].
Main topics were comparability testing, assays for product characterization, and process controls. OTP staffers emphasized the importance of determining process requirements early in development to avoid late changes and analytical method variability that could raise uncertainties likely to delay clinical trials. Products with complex mechanisms of action, they advised, stand to benefit from early product characterization and potency assay development. And developers of gene therapies should use multiple production lots during a clinical study to ensure product consistency and quality, even for treatments for very small patient populations.
Manufacturers raised questions about differing CMC issues between early Phase I and late-stage clinical trials and voiced concerns about product characterization related to autologous cell-based gene therapies. A main theme from FDA was the importance of sponsors establishing a well-controlled manufacturing process and qualified analytical testing well before administering any new gene product. While CBER plans to issue guidance on manufacturing changes and comparability for cellular and gene therapy products, the information provided at this session provides unofficial guidance for implementing changes in product manufacturing and the scope of comparability assessments and development studies expected to support such changes.

Health Alert for Parents: How one boy is thriving following treatment with a gene therapy after receiving an early diagnosis – PR Newswire
Posted: October 13, 2022 at 2:06 am
Two years ago, a mother received a phone call with a devastating diagnosis. That mother shares her son's experience with spinal muscular atrophy (SMA), a rare genetic disease, and how early diagnosis and treatment transformed his life.
BANNOCKBURN, Ill., Oct.12, 2022 /PRNewswire/ --
BACKGROUND:
Hannah Weaver did not think much about her son Payne's newborn screening test until she received a phone call five days after bringing him home from the hospital. The results showed Payne tested positive for spinal muscular atrophy (SMA), a rare, progressive neuromuscular disease and a leading genetic cause of infant death when left untreated that affects one in every 11,000 babies born in the U.S.1,2 SMA causes irreversible loss of motor neurons, which can rob infants of their ability to walk, swallow and even breathe.1,2 If left untreated in its most severe forms, 90% of children require permanent feeding and breathing support or pass away by their second birthday.3,4 SMA can progress quickly, making early diagnosis and treatment crucial.
Experience the full interactive Multichannel News Release here: https://www.multivu.com/players/English/9064751-novartis-spinal-muscular-atrophy-health-alert/
Knowing it was imperative to act fast, the Weaver family worked quickly to schedule appointments with specialists to discuss treatment options. Payne's care team went over the available treatment options for SMA, discussing the route of administration and available efficacy and safety data of each. Together, they decided to treat Payne when he was just a few weeks old with a gene therapy called ZOLGENSMA (onasemnogene abeparvovec-xioi), the only SMA treatment designed to directly address the genetic root cause of the disease by replacing the function of the missing or non-working SMN1 gene with a single, one-time dose.
Zolgensma has a boxed warning for acute serious liver injury and acute liver failure. In clinical trials, the most common side effects were elevated liver enzymes and vomiting. Please keep reading for additional important safety information and please see accompanying Full Prescribing Information.
Payne's parents are now able to plan for his future something that would not be possible without early intervention and treatment. They look forward to what he will accomplish next and celebrate every milestone along the way. On the heels of SMA Awareness Month, we kick off Newborn Screening Awareness Month this September, and Hannah is advocating for parents and physicians to recognize the early signs of SMA to avoid a delayed diagnosis.
Dr. Sandra Reyna (Vice President of Global Medical Affairs at Novartis Gene Therapies) and Hannah Weaver (SMA parent advocate) shared information on the signs of SMA, the importance of an early diagnosis, and how Zolgensma has the potential to transform the lives of babies born with this disease.
Results and outcomes vary among children based on several factors, including how far their SMA symptoms progressed prior to receiving treatment.
Please continue reading for Indication and Important Safety Information, and please see accompanying Full Prescribing Information including Boxed Warning.

About Spinal Muscular Atrophy
Spinal muscular atrophy (SMA) is a rare, genetic neuromuscular disease and a leading genetic cause of infant death.3,5Caused by the lack of a functional SMN1 gene, the most severe forms of SMA result in the rapid and irreversible loss of motor neurons, affecting muscle functions including breathing, swallowing and basic movement.1Severity varies across a spectrum of types corresponding to the number of copies of the back-up SMN2 gene.6The majority of patients with two copies of SMN2 develop Type 1, the most common form accounting for 60 percent of cases.4,7,8Type 1 is severe and, left untreated, leads to death or the need for permanent ventilation by the age of two in more than 90 percent of cases.3,5Most patients with three copies of SMN2 develop Type 2, accounting for about 30 percent of cases.4,8 Loss of motor neurons cannot be reversed, so it is imperative to diagnose SMA and begin treatment, including proactive supportive care, as early as possible to halt irreversible motor neuron loss and disease progression.9,10

About Fanconi Anemia
Fanconi Anemia (FA) is a rare pediatric disease characterized by bone marrow failure, malformations and cancer predisposition. The primary cause of death among patients with FA is bone marrow failure, which typically occurs during the first decade of life. Allogeneic hematopoietic stem cell transplantation (HSCT), when available, corrects the hematologic component of FA, but requires myeloablative conditioning. Graft-versus-host disease, a known complication of allogeneic HSCT, is associated with an increased risk of solid tumors, mainly squamous cell carcinomas of the head and neck region. Approximately 60-70% of patients with FA have a Fanconi Anemia complementation group A (FANCA) gene mutation, which encodes for a protein essential for DNA repair. Mutations in the FANCA gene leads to chromosomal breakage and increased sensitivity to oxidative and environmental stress. Increased sensitivity to DNA-alkylating agents such as mitomycin-C (MMC) or diepoxybutane (DEB) is a gold standard test for FA diagnosis. Somatic mosaicism occurs when there is a spontaneous correction of the mutated gene that can lead to stabilization or correction of a FA patients blood counts in the absence of any administered therapy. Somatic mosaicism, often referred to as natural gene therapy provides a strong rationale for the development of FA gene therapy because of the selective growth advantage of gene-corrected hematopoietic stem cells over FA cells.
About Leukocyte Adhesion Deficiency-I
Severe Leukocyte Adhesion Deficiency-I (LAD-I) is a rare, autosomal recessive pediatric disease caused by mutations in the ITGB2 gene encoding for the beta-2 integrin component CD18. CD18 is a key protein that facilitates leukocyte adhesion and extravasation from blood vessels to combat infections. As a result, children with severe LAD-I are often affected immediately after birth. During infancy, they suffer from recurrent life-threatening bacterial and fungal infections that respond poorly to antibiotics and require frequent hospitalizations. Children who survive infancy experience recurrent severe infections including pneumonia, gingival ulcers, necrotic skin ulcers, and septicemia. Without a successful bone marrow transplant, mortality in patients with severe LAD-I is 60-75% prior to the age of 2 and survival beyond the age of 5 is uncommon. There is a high unmet medical need for patients with severe LAD-I.
Rockets LAD-I research is made possible by a grant from the California Institute for Regenerative Medicine (Grant Number CLIN2-11480). The contents of this press release are solely the responsibility of Rocket and do not necessarily represent the official views of CIRM or any other agency of the State of California.
About Pyruvate Kinase Deficiency
Pyruvate kinase deficiency (PKD) is a rare, monogenic red blood cell disorder resulting from a mutation in the PKLR gene encoding for the pyruvate kinase enzyme, a key component of the red blood cell glycolytic pathway. Mutations in the PKLR gene result in increased red cell destruction and the disorder ranges from mild to life-threatening anemia. PKD has an estimated prevalence of 4,000 to 8,000 patients in the United States and the European Union. Children are the most commonly and severely affected subgroup of patients. Currently available treatments include splenectomy and red blood cell transfusions, which are associated with immune defects and chronic iron overload.
RP-L301 was in-licensed from the Centro de Investigaciones Energticas, Medioambientales y Tecnolgicas (CIEMAT), Centro de Investigacin Biomdica en Red de Enfermedades Raras (CIBERER) and Instituto de Investigacin Sanitaria de la Fundacin Jimnez Daz (IIS-FJD).

M6P Therapeutics Presents Novel AAV Gene Therapy Approach for the Treatment of Gaucher Disease at the ESGCT 29th Annual Congress – Business Wire
Posted: October 13, 2022 at 2:06 am
ST. LOUIS--(BUSINESS WIRE)--M6P Therapeutics (M6PT or the Company), a privately held life sciences company developing next-generation enzyme replacement and gene therapies for lysosomal storage disorders (LSDs), today announced a poster presentation titled, A novel AAV9 gene therapy for producing -glucocerebrosidase enzyme with high mannose 6-phosphate content to treat Gaucher disease, by Lin Liu, Ph.D., Director, R&D of M6P Therapeutics, at the 29th Annual Congress of the European Society of Gene and Cell Therapy (ESGCT). The Congress takes place in-person and virtually in Edinburgh, Scotland from Oct. 11-14, 2022 at the Edinburgh International Conference Centre.
The data from this preclinical study illustrate the potential of our AAV-GBA-S1S3 gene therapy candidate for the treatment of Gaucher disease, including neuronopathic phenotypes, said Pawel Krysiak, President and CEO of M6P Therapeutics. M012 is part of our pipeline of candidates leveraging a first-in-class co-expression S1S3 platform technology for the treatment of lysosomal storage disorders. Using our technology platform, we enhance mannose 6-phosphate content on lysosomal enzymes for both enzyme replacement and gene therapies, leading to improved enzyme uptake across target tissues.
Gaucher disease is a rare inherited metabolic disorder of defective lipid catabolism caused by deficient -glucocerebrosidase (GCase) encoding by the GBA1 gene resulting in accumulation of glycosphingolipids in the periphery and central nervous system (CNS). Multiple recombinant human GCase enzyme replacement therapies have been approved to treat Gaucher disease type 1, but there are no effective treatments to address the neuronopathic manifestations for Gaucher disease types 2 and 3. Gene therapy could be a potential therapeutic approach to treat all three types of Gaucher disease.
"In this study, gene copy and transcriptome analysis showed that the dosed novel M012 AAV vector enabled transduction of peripheral tissues and various regions of brain in wild-type mice post-intravenous injection, said Dr. Liu. We observed increased GCase enzyme activity with enhanced CI-MPR affinity in peripheral tissues of treated animals and noted strong GCase protein signal with broad distribution detected in M012 AAV vector-treated brain samples. These results strongly suggest that M012 AAV enables effective GCase cross-correction in the CNS. We look forward to sharing additional updates and data as the program progresses.
Presentation highlights from the poster include:
About M6P TherapeuticsM6P Therapeutics is a privately held, venture-backed biotechnology company developing the next-generation of targeted enzyme replacement and gene therapies for lysosomal storage disorders (LSDs). M6P Therapeutics proprietary co-expression S1S3 platform has the unique ability to enhance phosphorylation of lysosomal enzymes for both enzyme replacement and gene therapies, leading to improved biodistribution and cellular uptake of recombinant proteins and efficient cross-correction of gene therapy product. This can potentially lead to more efficacious treatments with lower therapy burden, as well as new therapies for currently untreated diseases. M6P Therapeutics team, proven in rare diseases drug development and commercialization, is dedicated to fulfilling the promise of enzyme replacement and gene therapies by harnessing the power of protein phosphorylation using its co-expression S1S3 platform. M6P Therapeutics mission is to translate advanced science into best-in-class therapies that address unmet needs within the LSD community.
