Orchard Therapeutics Receives EC Approval for Libmeldy for the Treatment of Early-Onset Metachromatic Leukodystrophy (MLD) – GlobeNewswire

First gene therapy to receivefull EU marketing authorization for eligible MLD patients

One-time treatment with Libmeldy has been shown to preserve motor and cognitive function

Achievement shared with research alliance partners Fondazione Telethon and Ospedale San Raffaele

BOSTON and LONDON and MILAN, Italy, Dec. 21, 2020 (GLOBE NEWSWIRE) -- Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, and its research alliance partners Fondazione Telethon and Ospedale San Raffaele, today announced that the European Commission (EC) granted full (standard) market authorization for Libmeldy (autologous CD34+ cells encoding the ARSA gene), a lentiviral vector-based gene therapy approved for the treatment of metachromatic leukodystrophy (MLD), characterized by biallelic mutations in theARSAgene leading to a reduction of the ARSA enzymatic activity in children with i) late infantile or early juvenile forms, without clinical manifestations of the disease, or ii) the early juvenile form, with early clinical manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive decline. Libmeldy is the first therapy approved for eligible patients with early-onset MLD.

MLD is a very rare, fatal genetic disorder caused by mutations in the ARSA gene which lead to neurological damage and developmental regression. In its most severe and common forms, young children rapidly lose the ability to walk, talk and interact with the world around them, and most pass away before adolescence. Libmeldy is designed as a one-time therapy that aims to correct the underlying genetic cause of MLD, offering eligible young patients the potential for long-term positive effects on cognitive development and maintenance of motor function at ages at which untreated patients show severe motor and cognitive impairments.

Todays EC approval of Libmeldy opens up tremendous new possibilities for eligible MLD children faced with this devastating disease where previously no approved treatment options existed, said Bobby Gaspar, M.D., Ph.D., chief executive officer of Orchard. Libmeldy is Orchards first product approval as a company, and I am extremely proud of the entire team who helped achieve this milestone. We are grateful for and humbled by the opportunity to bring this remarkable innovation to young eligible patients in the EU.

With Libmeldy, a patients own hematopoietic stem cells (HSCs) are selected, and functional copies of the ARSA gene are inserted into the genome of the HSCs using a self-inactivating (SIN) lentiviral vector before these genetically modified cells are infused back into the patient. The ability of the gene-corrected HSCs to migrate across the blood-brain barrier into the brain, engraft, and express the functional enzyme has the potential to persistently correct the underlying disease with a single treatment.

The EC approval of Libmeldy comes more than a decade after the first patient was treated in clinical trials performed at our Institute, and ushers in a remarkable and long-awaited shift in the treatment landscape for eligible MLD patients, said Luigi Naldini, M.D, Ph.D., director of the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy. Our team at SR-Tiget has been instrumental in advancing the discovery and early-stage research of this potentially transformative therapy to clinical trials in support of its registration through more than 15 years of studies supported by Fondazione Telethon and Ospedale San Raffaele, and we are extremely proud of this achievement and what it means for patients and the field of HSC gene therapy.

MLD is a heart-breaking disease that causes immeasurable suffering and robs children of the chance of life, said Georgina Morton, chairperson of ArchAngel MLD Trust. As a community, we have been desperate for a treatment for young MLD patients, and we are incredibly excited to now have such a ground-breaking option approved in the EU.

The marketing authorization for Libmeldy is valid in all 27 member states of the EU as well as the UK, Iceland, Liechtenstein and Norway. Orchard is currently undertaking EU launch preparations related to commercial drug manufacturing, treatment site qualification and market access.

Data Supporting the Clinical and Safety Profile of Libmeldy

The marketing authorization for Libmeldy is supported by clinical studies in both pre- and early- symptomatic, early-onset MLD patients performed at the SR-Tiget. Early-onset MLD encompasses the disease variants often referred to as late infantile (LI) and early juvenile (EJ). Clinical efficacy was based on the integrated data analysis from 29 patients with early-onset MLD who were treated with Libmeldy prepared as a fresh (non-cryopreserved) formulation. Results of this analysis indicate that a single-dose intravenous administration of Libmeldy is effective in modifying the disease course of early-onset MLD in most patients.

Clinical safety was evaluated in 35 patients with MLD (the 29 patients from the integrated efficacy analysis as well as six additional patients treated with the cryopreserved formulation of Libmeldy). Safety data indicate that Libmeldy was generally well-tolerated. The most common adverse reaction attributed to treatment with Libmeldy was the occurrence of anti-ARSA antibodies (AAA) reported in five out of 35 patients. Antibody titers in all five patients were generally low and no negative effects were observed in post-treatment ARSA activity in the peripheral blood or bone marrow cellular subpopulations, nor in the ARSA activity within the cerebrospinal fluid. In addition to the risks associated with the gene therapy, treatment with Libmeldy is preceded by other medical interventions, namely bone marrow harvest or peripheral blood mobilization and apheresis, followed by myeloablative conditioning, which carry their own risks. During the clinical studies, the safety profiles of these interventions were consistent with their known safety and tolerability.

About MLD and Libmeldy

MLD is a rare and life-threatening inherited disease of the bodys metabolic system occurring in approximately one in every 100,000 live births. MLD is caused by a mutation in the arylsulfatase-A (ARSA) gene that results in the accumulation of sulfatides in the brain and other areas of the body, including the liver, gallbladder, kidneys, and/or spleen. Over time, the nervous system is damaged, leading to neurological problems such as motor, behavioral and cognitive regression, severe spasticity and seizures. Patients with MLD gradually lose the ability to move, talk, swallow, eat and see. In its late infantile form, mortality at five years from onset is estimated at 50% and 44% at 10 years for juvenile patients.1

Libmeldy (autologous CD34+ cell enriched population that contains hematopoietic stem and progenitor cells (HSPC) transduced ex vivo using a lentiviral vector encoding the human arylsulfatase-A (ARSA) gene), also known as OTL-200, is approved in the European Union for the treatment of MLD in eligible early-onset patients. In the U.S., OTL-200 is an investigational therapy which has not been approved by the U.S. Food and Drug Administration (FDA) for any use. Libmeldy was acquired from GSK in April 2018 and originated from a pioneering collaboration between GSK and the Hospital San Raffaele and Fondazione Telethon, acting through their joint San Raffaele-Telethon Institute for Gene Therapy in Milan, initiated in 2010.

TSHA-101 CTA is the second clinical trial clearance received, in addition to TSHA-118s open investigational new drug application for CLN1

Interim data from Phase 1/2 trial anticipated in 2021

DALLAS, TX, USA I December 21, 2020 I Taysha Gene Therapies, Inc. (Nasdaq: TSHA), a patient-centric gene therapy company focused on developing and commercializing AAV-based gene therapies for the treatment of monogenic diseases of the central nervous system in both rare and large patient populations, today announced that Queens University in Ontario, Canada, received Clinical Trial Application (CTA) approval from Health Canada for its investigator-sponsored Phase 1/2 trial exploring TSHA-101, Tayshas investigational AAV9-based gene therapy, for the treatment of infantile GM2 gangliosidosis.

TSHA-101 will be the first bicistronic vector to enter a first-in-human clinical study, which is a significant milestone for Taysha and for the field of gene therapy, said Suyash Prasad, MBBS, M.SC., MRCP, MRCPCH, FFPM, Chief Medical Officer and Head of Research and Development of Taysha. GM2 is a devastating lysosomal storage disease with no approved treatments and todays CTA approval marks a formative moment for children suffering from this rapidly progressive and fatal disease.

The trial will be a single arm, open-label Phase 1/2 trial evaluating the use of TSHA-101 for the treatment of infants with GM2. The study will be sponsored by Queens University and led by Jagdeep S. Walia, MBBS, FRCPC, FCCMG, Clinical Geneticist and Associate Professor Head, Division of Medical Genetics (Department of Pediatrics) at Queens, and Director of Research (Department of Pediatrics), at the Kingston Health Sciences Centre.

Preclinical evidence to date supports our belief that TSHA-101, when given intrathecally as a bicistronic transgene packaged into a single AAV9 vector, has the potential to address the lysosomal enzyme deficiency, to change the disease trajectory and to improve patient survival, said Dr. Jagdeep S. Walia. We are pleased to have the support of Health Canada as we continue to advance TSHA-101.

Todays CTA approval is a culmination of our teams and Dr. Walias tireless efforts and a momentous occasion for children affected by GM2 along with their parents and caregivers, said RA Session II, Founder, President and CEO of Taysha. We are grateful to our partners at Queens University for their work to advance this gene therapy into the clinic.

About GM2 Gangliosidosis

GM2 gangliosidosis is a rare and fatal monogenic lysosomal storage disorder and a family of neurodegenerative genetic diseases that includes Tay-Sachs and Sandhoff diseases. The disease is caused by defects in the HEXA or HEXB genes that encode the two subunits of the -hexosaminidase A enzyme. These genetic defects result in progressive dysfunction of the central nervous system. There are no approved therapies for the treatment of the disease, and current treatment is limited to supportive care.

About TSHA-101

TSHA-101 is an investigational gene therapy administered intrathecally for the treatment of infantile GM2 gangliosidosis. The gene therapy is designed to deliver two genes HEXA and HEXB driven by a single promoter within the same AAV9 construct, also known as a bicistronic vector. This approach allows the simultaneous expression of a 1:1 ratio of the two subunits of protein required to generate a functional enzyme. It is the first and only bicistronic vector currently in clinical development and has been granted Orphan Drug and Rare Pediatric Disease designations by the U.S. Food and Drug Administration (FDA).

These Families Raised Millions To Fund Treatment For Their Kids’ Genetic Disorders. It Hasn’t Happened. – KCUR

Over the last several years, parents from across the country have appeared on television and news outlets to raise money to develop treatments for their children with rare genetic disorders.

Many of these families, including one from Kansas City, Missouri, have pinned their hopes on one Texas researcher, Dr. Steven Gray of the University of Texas Southwestern Medical Center in Dallas, who claims to be on the verge of treating a number of rare conditions. They've raised millions of dollars to fund his research, although breakthroughs haven't happened to the extent many had hoped.

While gene therapy holds great promise, the growing trend of family-funded research concerns some medical ethicists, who say that suggestions to parents that treatments may be imminent can raise thorny ethical issues.

These are parents. They are desperate. says Mayo Clinic bioethicist Megan Allyse. They are willing to try almost anything. They are in a pretty vulnerable position for somebody to come along and say, Give me your money, and I can make this better.

Further complicating the picture is the recent entry into the field of a private company, Taysha Gene Therapies, which says it will accelerate Grays research. That has divided his supporters and raised concerns about families who might be left behind.

Kim Fry, of Kansas City, Missouri, has a video on her phone of her son, Charlie, that was made in 2018 when he was 5 months old. It shows her bright-eyed boy gently shaking in his father's lap, as if shivering from cold.

Those little tremors sent the family on a year-long odyssey that led to a frightening diagnosis. A genetic test showed Charlie had an incredibly rare mutation in a single gene, SLC6A1. The mutation typically causes intellectual disabilities and epilepsy starting around the age of three-and-a-half that can severely affect patients for the rest of their lives.

Doctors told Kim and Nate there was no treatment available to help their son.

At that moment, you just feel crushed and kind of begin grieving for the life you think your childs going to have, Kim said.

Rare genetic disorders have generally received little attention from biotech companies because the markets for treatments are so small.

But shortly after the diagnosis, Kim met Amber Freed, a mother from Denver who seemed to have found a solution. After her son, Maxwell, was diagnosed with the same mutation a year earlier, Freed met Gray, a molecular biologist who had focused on gene therapy while doing a post-doctoral fellowship at UNC Chapel Hill.

Gray was developing treatments or even possible cures for conditions caused by single-gene mutations, and he had agreed to work on SLC6A1. But it would be up to Freed to provide Gray with the millions of dollars he would need to do this work.

With the possibility of a treatment suddenly on the table, Kim and Nate immediately joined Amber in raising money through the organization she started, SLC6A1 Connect, and their own campaign, A Cure For Charlie. Their goal was to create a treatment and bring it to clinical trial before Charlie turned three-and-half, hoping to block the severe effects of the mutation and giving him a chance to live a regular life.

Once the funding is there, then all the science is going to move into place, so really the only hurdle that were facing right now between us and the cure is the funding, Nate said in fall of 2019.

Family fundraisers

Family fundraisers are a departure from how medical research is usually funded, typically through the National Institutes of Health, large foundations and advocacy groups.

Nevertheless, families like the Frys have appeared on news outlets and in publications throughout the country in recent years, from Good Morning America and ABC News to People magazine and countless local news shows, to raise money for research.

The children have been diagnosed with many different genetic disorders, but their stories are similar. They all have rare gene mutations that will lead to serious mental or physical declines or early death, and their parents are pinning their hopes on Gray to develop treatments.

They call themselves the Steve Gray Parents.

Gray himself has appeared in articles and videos, including one produced by UT Southwestern about Willow Canaan, a girl from Mississippi who has multiple sulfatase deficiency.

A lot of the families that we interact with, they are coming to us with really sick kids. I think knowing their story, knowing that one child, gives us a face, gives us a mission that if we can move fast enough theres hope that we could treat and we make things different for that specific child, Gray said in one video.

Gray became a go-to researcher for rare disease families after his treatment of Hannah Sames, a girl from New York with a degenerative genetic disorder called giant axonal neuropathy.

In a 2016 clinical trial, Sames was injected with a manufactured virus that contained a working copy of the gene that was mutated. Through this adeno-associated virus delivery method, the normal gene would take over from the mutated one and stop the degeneration from happening.

The treatment slowed the progress of Hannahs disease, according to Gray, but it wasnt a cure. In a 2019 interview on Connecticut Public Radio, Hannahs mother, Lori, said the family was seeking additional treatment.

But Gray thinks the same method could be used to treat and possibly cure all kinds of genetic disorders, including the SLC6A1 mutation

Were due for another leap in technology, Gray told KCUR in 2019. Were going to have a better virus technology, better ways to deliver genes, and I can see that just making a further leap for the whole field.

Gray, who says he has been involved in developing treatments for two dozen diseases, has accepted money from families to pay for the high costs of manufacturing viruses, doing toxicology studies and running clinical trials. Many of these family groups had raised more than a $1 million each from their friends, relatives and neighbors.

Though these families have been effective at raising money, bioethicist Allyse worries that without the peer review process that traditional funders use, they may not be in the best position to decide what research is likely to get results.

The potential problem with going around that process is that its possible to sort of go down avenues that are less supported by the literature, that are less in line with the scientific consensus, Allyse said.

But those doubts have done little to discourage dedicated parents like Amber Freed.

In early December 2019, Freed hosted the second annual SLC6A1 research symposium in a hotel conference room in downtown Baltimore. Freed quit her job in finance after her sons diagnosis to dedicate herself to advancing a treatment, and she began organizing annual SLC6A1 research symposiums in 2018 to drum up interest in the work.

Shes also held charity golf tournaments, set up fundraising campaigns with companies like Amazon and Pizza Hut, and helped arrange the creation of genetically altered mice in China for research.

During the last two years, Freed has cultivated relationships with genetic researchers from all over the world, and as the sleepy scientists who traveled to Baltimore to take part in the symposium wandered into the conference room early on a Friday morning, she greeted them like family, with big hugs and smiles.

Alex Smith

Despite Freeds seemingly endless enthusiasm, she made clear in her welcoming speech to the scientists that, unlike them, her involvement in SLC6A1 research didnt happen by choice.

But to be honestI dont want to be here, read a slide projected behind her at the end of her remarks.

Some improvements but no 'home run'

Toward the end of the day, Gray took the podium to deliver an update on research from his lab. For many in the audience, this was the days main event.

His teams early research using the treatment showed some improvements in motor and behavioral skills in young, genetically altered mice that were treated before symptoms had appeared. But there was no change in mice that already had symptoms.

I think treating at an early age, were seeing some signs of improvements and some nice signals that our vector is doing something positive, but, you know, its not a home run, Gray explained.

Though it wasnt the result Freed dreamed of, she was encouraged that the research appeared to be on the right path.

Gray insisted he had tried to be careful about managing expectations for families funding his work, but between symposium talks, he also said he had recently shifted course on working with them.

Im really having to say no a lot now, Gray told KCUR. Im kind of moving into a point where we were trying not to say no, and we were trying to work on everything that the science made sense. But there is a point where you just have to say, You know Ive got to focus on what Im doing, and theres a limit.

While Grays work did lead to a treatment for Hannah Sames, similar breakthroughs havent come in time for other families.

Laura King Edwards of Charlotte, North Carolina, started working with her family to raise money for Grays work after her baby sister, Taylor, was diagnosed with a form of a rare disorder called infantile Batten disease in 2006.

The family didnt have a lot of hope the research would lead to a treatment in time to help Taylor, and she died two years ago at age 20.

Edwards says that looking back, she sometimes regrets all the time she spent running a fundraising organization.

Id spend hours up at night dealing with tech issues on our website, for example, or responding to emails from people all over the world, knowing that thats time that maybe I couldve spent with my little sister while she was still here, Edwards says.

Nevertheless, even after Taylor was gone, her family continued to support Grays work through their organization, Taylor's Tale.

A new player

Not long after the conference in Baltimore, however, the race for a SLC6A1 treatment slowed to a crawl.

When the COVID-19 pandemic hit, scientific studies and medical trials across the country were stopped and research funds were directed to coronavirus research.

The therapists who work with Amber and Kims sons were unable to meet with them in person, and the boys started to backslide on some of their developmental progress.

Then, after the initial waves of the coronavirus subsided, hopes for Grays research came roaring back to life when a new company, Taysha Gene Therapies, announced it would partner with UT Southwestern, offering a boost to the research and development beyond what families could provide.

They could get it to a certain place, said Taysha founder R.A. Session II, But when it needs to get to kind of the meaningful level in order to get it into late-stage clinical trials, this is where they just dont necessarily have the capability. And so I think this is where you would see programs then transitioning into a companys hands in order to kind of pursue them and move them forward.

In April, Taysha announced a partnership with UT Southwestern that would fund Grays research and work to move it more quickly into clinical trials and possible treatment. Gray was named chief scientific officer.

The company said the family fundraising would no longer be needed.

For some parents, like Doug and Kasey Woleben of Dallas, that was great news. Theyve raised around $1 million for research to treat Leigh syndrome, which affects their 8-year-old son, Will.

We were excited, thrilled to know that were now off the hook for millions and millions and millions of dollars. And that Taysha and UT Southwestern are trying to push this program and move it forward as quickly as possible. So for us, it was a miracle, Kasey said.

But Taysha's involvement and its timeline have brought disappointment for other families. The company's first clinical trials, to treat a mutation that causes Tay Sachs disease, were planned to start in Canada at the end of 2020 but only received approval from the Canadian government this week.

The company says it plans to seek permission to test treatments for three other conditions, including the SLC6A1 mutation, by the end of 2021, but it has not announced any dates for beginning trials.

For Amber Freed and Kim Fry, Tayshas timeline is problematic. Both of their sons were expected to exhibit epilepsy symptoms before the end of next year and so they would see little benefit from treatment initiated after that.

Im very disappointed, Freed said in September. If you had asked me this time last year, I would have fully expected to be in a clinical trial right now.

Different priorities

Session insists that Tayshas timeline and priorities on are based on what the research shows is safe and effective.

Weve allowed the science to kind of move forward at the pace the science moves, Session says. Then we move it forward into the clinic based on that science.

But to Freed, the goal of fast-tracking to trial, even one that would have only resulted in a slight improvement for her son, appears much less likely now that Taysha is involved.

Once you hand over the reins to a biotech, you lose decision-making power as a nonprofit organization, and you abide by their timeline and not necessarily your own, Freed said. In my case, we are racing to get this therapy into children like Maxwell and Charlie as quickly as possible, so we need it done tomorrow.

For other Gray supporters, however, the future is even less clear. Tayshas development pipeline does not include treatments for some of the conditions that Gray had previously been working with families to develop, including Charcot-Marie Tooth, Krabbe disease and multiple sulfatase deficiency.

UT Southwestern researchers will continue to research those conditions, according to a university spokesman, and Taysha says it plans to expand its pipeline in the future.

Terry Pirovolakis, who had enlisted Grays help to develop a treatment for spastic paraplegia 50, which affects his son, Michael, will not be involved with Tayshas work. Hell only continue to work with UT Southwestern directly.

From my perspective, it was, thats great. Tayshas gonna come in and maybe save the world, but I dont want to be part of it 'cause theyve got a lot of stuff they gotta work out, and Im not going to wait around for them to figure it out, Pirovolakis said.

Pirovolakis, who lives in Toronto, has raised more than $1.5 million since May 2019 through his online campaign, Cure Michael, which was the most successful GoFundMe campaign in Canada last year.

Expectations vs. reality

He says that while he has been comfortable working with Gray, he believes that drug companies, which depend on the involvement of families for rare disease research, can mislead parents about what might be possible for their children.

The industry, as a whole, I think, maybe sets expectations that are higher than reality," Pirovolakis said. "We see these presentations at the conferences of these kids doing amazing things, like a 4-year-old that has no brain function pretty much, going to school two years later. Its remarkable.

"But that was five or 10 years of research. So I think that expectations from the industry are maybe what cloud us as parents in the hope that something amazing is gonna happen for our kids.

CureCMT4J, a foundation created to advance research on Charcot-Marie Tooth by parent advocate Jocelyn Duff, an early supporter of Gray, also is no longer involved with the researchers work. Duff said the organization had moved in a different direction, but she declined the provide details. The group had raised $1.3 million as of fall 2020.

Some ethicists have also raised questions about the costs of rare disease treatment, and they point to a drug previously developed by members of the Taysha team as a prime example of their concern.

Several members of the Taysha team, including Session, directors Sean Nolan and Phillip Donenberg, and others, earned their reputation for success as part of a AveXis, a company that developed the breakthrough treatment for spinal muscular atrophy, Zolgensma.

Zolgensma was introduced by drug giant Novartis last year with a price tag of more than $2.1 million, making it the most expensive drug in the country.

On the one hand, you could say thats a winning team, said Megan Allyse. On the other hand, you could say is that the team you want to be on if what youre trying to do is generate not just effective treatments, but accessible treatments?

Session says that Taysha currently has no plans regarding the pricing or accessibility of any treatments the company might develop.

We should be so blessed to be able to have a discussion on pricing because then were talking about an approved therapy, Session says. But were not there yet. So what I would say is the company is focused on getting these drugs into patients effectively and safely as efficiently as possible.

Taysha announced in November that it raised more than $275 million in private financing and an initial public offering.

For Kim Fry and Amber Freed, however, the focus is still very much on what can be done for their sons.

The women are continuing to raise money, but they have shifted to other researchers and technologies. And they have adjusted their expectations.

Frys son, Charlie, started having more significant seizures earlier in the year and is now taking medication to reduce them.

She still thinks a treatment within the next year or two could help her son and others like him, although not in the way she had once imagined.

It may not be a 100% home run where they live 100% the life we hoped. But theyll still have a better life than they are living today, Fry said. I lose sleep every night over the thought that it might be too late, but Im still hopeful that there will be benefit for them.

Amryt Granted Orphan Drug Designation by the FDA for AP103 – GlobeNewswire

Amryt Granted Orphan Drug Designation by the FDA for AP103

DUBLIN, Ireland, and Boston MA, December 23, 2020, Amryt (Nasdaq: AMYT, AIM: AMYT), a global, commercial-stage biopharmaceutical company dedicated to developing and commercializing novel therapeutics to treat patients suffering from serious and life-threatening rare diseases, is pleased to announce today that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for AP103 for the treatment of Dystrophic Epidermolysis Bullosa ("DEB"). AP103 is based on Amryt'sgene-therapy platform technology and offers a potential treatment for patients with DEB, a subset of EB.The FDAsOffice of Orphan Products Development (OOPD) grants orphan drug designation to support the development of medicines for rare diseases, that affect fewer than 200,000 people inthe United States. Orphan drug designation may allowAmrytto be eligible for a seven-year period of U.S. Marketing exclusivity upon approval of AP103 and a waiver of the Prescription Drug User Fee Act (PDUFA) filing fees, subject to certain conditions.

AP103 is based on a new gene therapy delivery platform, in-licensed by Amryt in March 2018, that utilises a non-viral delivery vector, HPAE (Highly Branched Poly -Amino Ester), designed to deliver the correct collagen VII gene into skin cells.

Joe Wiley, CEO of Amryt Pharma, commented:"Receiving an orphan drug designation from the FDA for our gene-therapy candidate, AP103, is a significant development for patients suffering fromEB and provides additional momentum to our development pipeline.Unlike other gene therapies that rely on viral vectors, AP103 is based on a novel polymer-based topical delivery platform, which we believe offers potential advantages in the gene-therapy field and haspotential to be used in other genetic skin conditions.

About AmrytAmryt is a biopharmaceutical company focused on developing and delivering innovative new treatments to help improve the lives of patients with rare and orphan diseases. Amryt comprises a strong and growing portfolio of commercial and development assets.

Amryts commercial business comprises two orphan disease products.

Amryt's lead development candidate, FILSUVEZ (Oleogel-S10) is a potential treatment for the cutaneous manifestations of Epidermolysis Bullosa (EB), a rare and distressing genetic skin disorder affecting young children and adults for which there is currently no approved treatment. FILSUVEZ has been selected as the brand name for the product. Amryt does not have regulatory approval for FILSUVEZ to treat EB. In September and October 2020, Amryt reported positive results from its pivotal global Phase 3 trial in EB. The product has been granted Rare Pediatric Disease Designation and has also received a Fast Track Designation from the U.S. Food and Drug Administration.

Myalept / Myalepta (metreleptin) is approved in the US (under the trade name Myalept) as an adjunct to diet as replacement therapy to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy (GL) and in the EU (under the trade name Myalepta) for the treatment of leptin deficiency in patients with congenital or acquired GL in adults and children two years of age and above and familial or acquired partial lipodystrophy (PL) in adults and children 12 years of age and above for whom standard treatments have failed to achieve adequate metabolic control. Metreleptin is also approved for lipodystrophy in Japan. Generalised and partial lipodystrophy are rare disorders characterised by loss or lack of adipose tissue resulting in the deficiency of the hormone leptin, produced by fat cells and are associated with severe metabolic abnormalities including severe insulin resistance, diabetes, hypertriglyceridemia and fatty liver disease.

Juxtapid/ Lojuxta (lomitapide) is approved as an adjunct to a low-fat diet and other lipid-lowering medicinal products for adults with the rare cholesterol disorder, Homozygous Familial Hypercholesterolaemia ("HoFH") in the US, Canada, Columbia, Argentina and Japan (under the trade name Juxtapid) and in the EU and Brazil (under the trade name Lojuxta). HoFH is a rare genetic disorder which impairs the body's ability to remove low density lipoprotein ("LDL") cholesterol ("bad" cholesterol) from the blood, typically leading to abnormally high blood LDL cholesterol levels in the body from before birth - often ten times more than people without HoFH - and subsequent aggressive and premature cardiovascular disease.

In March 2018, Amryt in-licensed a pre-clinical gene-therapy platform technology, AP103, which offers a potential treatment for patients with Dystrophic Epidermolysis Bullosa, a subset of EB, and is also potentially relevant to other genetic disorders.

CRISPRs Big Year: Top Breakthroughs of 2020 – Freethink

CRISPR, a tool for editing the genetic code in living organisms, was first discovered in 2007. Since then, the prospect of eliminating diseases by editing the human genome has been hovering on the edge of science fiction and reality.

Until 2020.

Here are four incredible CRISPR breakthroughs that happened this year.

"When we think about how CRISPR will be applied in the future, that is really one of the most important bottlenecks to the field right now: delivery," Jennifer Doudna, who won the Nobel Prize in Chemistry along with Emmanuelle Charpentier in October for creating CRISPR, told Genetic Engineering News.

Accessing DNA in living cells has been the biggest challenge for CRISPR. The most widely used CRISPR gene editing system uses a protein called Cas9, which is naturally found in bacteria and archaea. Their biological role is to fight off viruses by destroying the viruses' DNA and cutting it out of their genomes.

However, scientists can use them as "DNA scissors," which can be used to cut disease-causing mutations out of any DNA.

The trouble is Cas9, as well as other proteins used in different CRISPR systems, are all really bulky, which makes it difficult to access the smallest nooks and crannies of the human genome.

However, in July Doudna and her University of California Berkeley team announced that they found a new Cas protein.

Drumroll, please. Enter the tiny Cas (pronounced "Cas-phi").

At practically half the size, Cas can reach areas of the human genome that most CRISPR gene editing proteins cannot. This new protein could be a game-changer for genetic engineering.

This year researchers announced the results of an on-going clinical trial that tested CRISPR's ability to edit the DNA of living cells and possibly cure genetic diseases in humans.

The study focused on two of the most common genetic disorders globally sickle cell disease and beta-thalassemia. The only cure for these blood diseases is via a stem cell transplant from a viable donor. But often, the recipients have to take immunosuppressants for months or years, with difficult side effects.

The trials involved collecting blood stem cells from the patients. Then, researchers used CRISPR to alter the cells' genes, and finally transplanted the stem cells back into the patients. Several months later, when patients reported that their symptoms were gone, the scientific community hailed the study as a gene therapy breakthrough calling it a cure.

"I am encouraged by the preliminary results, which demonstrate, in essence, a functional cure for patients with beta thalassemia and sickle cell disease," researcher Haydar Frangoul said in a news release.

The next step is expanding the study by enrolling 45 patients and observing them long-term.

The U.S. doesn't have enough donor organs to fulfill every need. As a result, approximately 17 people die each day because they couldn't get the liver, heart, or lung they required.

To solve this shortage, scientists have been looking into cross-species donation or xenotransplantation for a decade, with little progress. Our immune system is designed to attack intruders, which is excellent when you have the flu, but it makes xenotransplantation practically impossible.

"The approach, if validated through further studies, could help solve global organ shortage (and) alleviate transplantation needs."

Now, thanks to CRISPR, xenotransplantation could be possible. Using CRISPR, researchers at Qihan Biotech modified the DNA of pigs to make them more compatible with humans. The researchers made 13 genetic modifications to the pigs, all in the hopes of making them more acceptable to the human body. In vitro lab tests showed promise cells from the gene-edited pigs appeared less likely to be rejected by the human immune system than those of unmodified animals.

"The approach, if validated through further studies, could help solve global organ shortage (and) alleviate transplantation needs," Qihan Biotech co-founder George Church said in a press release.

Further studies are underway: the team is now testing an organ transplant from a gene-edited pig into a primate.

Scientists at the Casey Eye Institute in Portland used CRISPR inside the human body for the first time in a patient that had an inherited form of blindness.

Doctors dropped the gene-editing tool behind the retina via three drops of liquid that passed through a tube the size of a human hair. Once in the body, CRISPR went to work. It snipped the mutated gene on both sides of the problem area. They hope that once the mutation was removed, the snipped DNA will reconnect itself, allowing the gene to function as it should. They are now in clinical trials.

"Once the cell is edited, it's permanent and that cell will persist hopefully for the life of the patient," because these cells don't divide, said one study leader not involved in this first case, Dr. Eric Pierce at Massachusetts Eye and Ear.

If all goes according to plan, the patient should regain their vision within a few months. Next, the doctors plan to further test the procedure on 18 children and adults.
