MILAN, Italy, Sept. 16, 2024 (GLOBE NEWSWIRE) -- AAVantgarde Bio (AAVantgarde), an Italy-based global biotechnology company, announced that the first subject has been dosed in the LUCE-1 trial, a Phase 1/2 open label clinical trial to assess safety and tolerability of AAVB-081, using the company’s proprietary dual hybrid gene therapy platform to deliver MYO7A protein in subjects with retinitis pigmentosa related to Usher Syndrome Type 1B (USH1B). This dual-AAV technology for large gene delivery comes from the research of Prof. Alberto Auricchio at TIGEM, an international research institute based in Naples that is owned and managed by the Telethon Foundation. AAVantgarde is a spin-off of TIGEM, and has an exclusive license for the AAV-dual technology for inherited retinal diseases. The first subretinal gene therapy procedure in the LUCE-1 study was supervised by Prof. Francesca Simonelli, Head of the Ophthalmology Unit at the University Hospital of Campania “Luigi Vanvitelli” (Naples). This hospital is one of 3 clinical sites for the Phase 1/2 trial. Dr. Simonelli is global Chief Investigator at the University Hospital of Campania “Luigi Vanvitelli” that is the lead dosing site for the LUCE-1 study. “I am delighted to be involved as Principal Investigator in this first-in-human Phase 1/2 clinical study of AAV-081 for patients with retinitis pigmentosa related to USH1B,” said Prof. Simonelli. “Through this innovative program, we aim to revolutionize our approach to understanding and treating these underserved patients. We are poised to generate robust evidence that will not only advance scientific knowledge, but also directly impact patient care.” Dr. Jayashree Sahni, CMO of AAVantgarde said, “It is an honour to work closely with Prof. Simonelli in this first-in-human clinical trial and leverage her great expertise in developing gene therapies for ophthalmology indications, with a goal of bringing this potentially novel therapy to the USH1B patient community as expeditiously as possible.” Prof. Alberto Auricchio, Founder and CSO of AAVantgarde added, “It is very exciting to have our dual hybrid technology finally tested clinically in an ophthalmology indication. I am very hopeful that all these years of research prove their value in helping these patients that have such a high unmet need.” Dr. Natalia Misciattelli, CEO of AAVantgarde added, “We are honoured to have Prof. Simonelli as Principal Investigator for this clinical study aimed at providing hope for USH1B patients that have no therapeutic options to prevent them from losing their sight. Prof. Simonelli is a pioneer in gene therapy in ophthalmology and her extensive experience in this space will be invaluable to the successful development of this novel therapy.” About the AAVB-081 programAAVB-081 is an intra-retinal AAV8-based dual hybrid product targeting MYO7A-associated Usher syndrome (USH1B). AAVantgarde’s dual hybrid platform uses two AAV8 vectors, each containing one half of an expression cassette encoding for the Myo7A gene and works at the cell nucleus level, recombining the two halves of the transgene back into a single one within the cell. This technology translates into an efficient recombination that generates therapeutically meaningful protein levels in animal models. About the LUCE-1 TrialLUCE-1 is a Phase 1/2 multicenter, open-label, dose escalation study investigating safety, tolerability and preliminary efficacy of 3 dose levels of dual AAV8.MYO7A (AAVB-081) administered subretinally in subjects with retinitis pigmentosa associated with Usher Syndrome Type 1B. About Usher syndrome type 1BUsher syndrome type 1B (Usher1B) is an inherited disease that affects the retina and the inner ear. Usher1B is caused by mutations in the MYO7A gene. The therapeutic gene to treat Usher1B is 6.7 kb long and is therefore too large to fit inside a standard AAV vector. Approximately 20,000 patients in the U.S. and E.U. have Usher1B. These children are born deaf, have vestibular dysfunction, and begin to progressively lose vision in their first decade of life. Although there are surgical treatments available to treat deafness in these patients, there are no treatments available to treat progressive vision loss and blindness in these patients. About AAVantgarde BioAAVantgarde Bio is a clinical stage, Italian headquartered, international biotechnology company that has developed two proprietary Adeno-Associated Viral (AAV) vector platforms to address the gene therapy cargo capacity limitations of AAV vectors. The AAVantgarde platforms could be used to deliver large genes to ocular and non-ocular tissues. Co-founded by Professor Alberto Auricchio at TIGEM (Telethon Institute of Genetics and Medicine) in Naples, Italy, and Telethon Foundation, AAVantgarde will initially validate the platform in the clinic in two inherited retinal diseases with clear unmet need.

Researchers at the non-profit n-Lorem discovered and developed a personalised ASO therapy to treat a rare neurological disease. Credit: SurfsUp via Shutterstock. A patient with a rare progressive neurodegenerative disorder receiving a personalised experimental antisense oligonucleotide (ASO) treatment developed by the non-profit n-Lorem has reported improvements in seizure severity and quality of life. The patient, named Susannah, has a rare condition called KIF1A-associated neurological disorder (KAND). US-based non-profit n-Lorem developed a personalised, experimental ASO medicine specific to Susannah’s genetic mutation. After receiving her first dose of the personalised medicine, her seizures fell to under 30 per week and she has remained stable. KAND is caused by mutations in the KIF1A gene, leading to progressive motor impairments, developmental delays, and cognitive difficulties. Management of KAND mainly focuses on addressing symptoms and improving quality of life through supportive therapies, like speech or physical therapy. There are no other therapies for KAND in clinical development, as per GlobalData’s Pharma Intelligence Center. GlobalData is the parent company of Pharmaceutical Technology . Following the ASO treatment, the patient’s ability to walk also improved after one month; compared to having an average of 26.2 falls per day before treatment, she now experiences up to seven falls daily, with many days without any falls. See Also: Eli Lilly boosts sales forecast by $3bn as diabetes and weight loss drugs propel revenue Recursion and Exscientia merge to form drug discovery company Data from the study published in Nature Medicine also detail notable advancements in speech, attention, group interaction, and motor functions, while the patient’s cognitive abilities have remained stable. Susannah has continued on the ASO treatment for 20 months, with a favourable safety and tolerability profile. ASO therapies work by using short, synthetic strands of nucleic acids to target and modify specific genes, reducing the production of harmful proteins or correcting genetic defects. The treatment developed by n-Lorem targets and corrects the harmful version of the KIF1A gene. Founded by former Ionis Pharmaceuticals ’ CEO Stanley Crooke, n-Lorem aims to bring ASO therapies to patients who are diagnosed with a disease that is found in less than 30 people. Research physicians submit an application to the non-profit, which examines if the patient’s genetic mutation is amendable to the ASO technology. More than 130 patient applications have so far been approved by the organisation for a range of different mutations. There has been an increase in the number of nonprofits developing rare disease medications where the patient population size is too small for commercialisation. Italian research charity Telethon Foundation manufactures and distributes Strimvelis, a gene therapy for rare disease adenosine deaminase severe combined immunodeficiency (ADA-SCiD). The non-profit took over development after it was dropped by its pharmaceutical company in 2022, allowing patients to receive treatment. ASO therapies have long been investigated in rare diseases because they target the cause of disease at the molecular level. Researchers have also developed candidates that are approved to treat conditions affecting larger patient populations. Biogen ’s ASO Spinraza (nusinersen) secured approval for treating the movement disorder spinal muscular atrophy in 2016, pulling in $610.5m in sales in 2023 as per the company’s financials. In the announcement accompanying the case study, n-Lorem’s CEO Stanley Crooke said: “Prior to treatment, Susannah’s disease had progressed to her being mostly in a wheelchair, approaching nonverbal with debilitating seizures that limited her and her family’s quality of life. Susannah has now been on treatment for more than 20 months and we continue to observe improvements in her mobility, neurological function, and quality of life.” The non-profit, which launched in 2020, is also conducting a KIF1A outcome measures, assessments, longitudinal and endpoints (KOALA) study to understand how KAND symptoms develop and change over time.

The FDA’s rare disease innovation hub aims to streamline rare disease drug development. Credit: PeopleImages.com – Yuri A via Shutterstock. A new rare disease innovation hub set up by the US Food and Drug Administration (FDA) aims to expedite the development and approval of orphan drugs. Rare disease clinical trials can be tricky to navigate, especially for conditions with very few patients. Moreover, even after clinical success, some therapies for rare diseases have been dropped by companies due to the high development costs. The FDA’s hub will act as a central point of connection and engagement with the rare disease community, aiding the navigation of FDA-related concerns. It will enhance inter-centre collaboration on scientific, clinical, and policy issues in rare disease product development, said the agency. It also aims to advance novel endpoints, biomarkers, trial designs, real-world evidence, and statistical methods. The hub will be co-led by Dr. Patrizia Cavazzoni, director at the Center for Drug Evaluation and Research (CDER), and Dr. Peter Marks, director at the Center for Biologics Evaluation and Research (CBER). In 2023, over half of all novel drugs and biologics approved by the FDA’s CDER and CBER were to treat or prevent a rare disease. While there have been important advances in treatments for rare diseases, more needs to be done, said the co-leaders in the announcement: See Also: Conflict means millions of children are missing vaccinations, UN says Moderna and Mitsubishi Tanabe link on mRNA vaccines in Japan “We see huge potential in establishing a new model, within the FDA, to leverage cross-agency expertise and greatly enhance our inter-centre connectivity to spur the development of treatments for rare diseases.” Such initiatives can be helpful to address concerns raised by key stakeholders in the field. The Italian research charity Telethon Foundation manufactures and distributes the gene therapy Strimvelis, which is used to treat the rare disease adenosine deaminase severe combined immunodeficiency (ADA-SCiD). Speaking to Pharmaceutical Technology , Francesca Pasinelli, general manager of Telethon Foundation, highlighted how one regulatory bottleneck in rare disease development affects operations. “Overall resource challenges faced by regulatory authorities extend the timelines for obtaining feedback to facilitate the development of products. We therefore understand that it might be difficult for regulatory authorities to speed up the process or even rethink some of the procedures when experts are lacking.” In order to advance treatments for patients with rare diseases, the FDA says it will hold an open public meeting later this year that will include the establishment of a public docket. This aims to provide further information about the vision for the Hub and get feedback from the community to help shape the Hub’s priorities and initiatives.
