Inherited SP-B deficiency is an ultra-rare monogenic cause of fatal respiratory distress syndrome in newborn infants with few, if any, options for long-term survival Highly encouraging preclinical data highlight the possibility of lifelong treatment from a single administration of AVG-002 with preparations for clinical development underway Follows recent grant of Rare Pediatric Disease Designation from FDA 3 December 2024 – AlveoGene (or ‘the Company’, www.alveogene.com), a company focused on transforming rare respiratory disease outcomes using inhaled gene therapy, announces that the US Food & Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to AVG-002, the Company’s novel, inhaled gene therapy for lethal neonatal Surfactant Protein B (SP-B) deficiency. This award follows the recent grant of Rare Pediatric Disease Designation for AVG-002 from FDA in November. Inherited SP-B deficiency is an ultra-rare monogenic cause of fatal respiratory distress syndrome in newborn infants with very limited treatment options. This genetic disorder, affecting approximately 1 in 1 million newborns in the US and Europe, results from mutations in the SP-B gene, which is essential for lung function and survival. Current treatments are mainly supportive, including mechanical ventilation and surfactant replacement, however these interventions only provide temporary relief and once genetic diagnosis of SP-B deficiency is confirmed, treatment is usually withdrawn and patients die. The only definitive treatment, lung transplantation, is often not accessible owing to the scarcity of donor organs for newborns and the risks involved, leaving few if any viable options for long-term survival. David Hipkiss, Executive Chair of AlveoGene, said: “Receiving Orphan Drug Designation from FDA for AVG-002 represents another important milestone for AlveoGene, following the recent grant of Rare Pediatric Disease Designation for the same candidate. Both awards highlight the significant unmet need for novel therapies targeting SP-B deficiency in newborn infants, which is invariably fatal within a few months and for which there are very limited treatment options. AVG-002, a novel gene therapy, has been designed using our InGenuiTy® technology to reach deep into the affected lung tissues to restore lung function and could provide a lifelong treatment from a single administration. We are totally committed to advancing AVG-002 as quickly as possible to provide a transformative, life-saving treatment for patients.” AVG-002 is being developed by AlveoGene using its InGenuiTy® platform, which employs a unique pseudotyped lentiviral vector to deliver a functional SP-B gene directly to the neonatal deep lung alveolar region with high efficiency and efficacy via respiratory instillation. Preclinical data in SP-B gene knock-out murine models demonstrate that a single dose of AVG-002 extends survival substantially longer when compared with reported data of other SP-B deficiency candidates in development, offering the possibility of a lifelong treatment from a single administration. These data are further reinforced by findings that confirm the restoration of normal lung histology and function following AVG-002 treatment in disease-induced lung tissues. Based on these highly encouraging findings, AlveoGene is advancing its preparations for the clinical development of AVG-002 in lethal neonatal SP-B deficiency with the possibility of filing for marketing authorisation by 2028. FDA’s Office of Orphan Drug Products grants Orphan Drug Designation (ODD) to support the development of medicines for rare disorders that affect fewer than 200,000 people in the US. Under the Orphan Drug Act, ODD qualifies a company for incentives, including tax credits, exemptions from certain FDA fees for clinical trials, and the potential for seven years of market exclusivity following drug approval. AlveoGene is a lung-targeted, inhaled gene therapy company aiming to transform the standard of care in respiratory disease and providing therapeutic solutions where few, if any, effective options exist. The Company is advancing a pipeline of novel inhaled gene therapies with enhanced safety, efficacy, durability and improved targeting to lung tissues, based on its unique InGenuiTy® technology. AVG-002 and AVG-003 are potentially first-in-class disease-modifying therapies for newborns with rare lethal Surfactant Protein B (SP-B) and ABCA-3 deficiencies, respectively. AVG-002 is being developed under Rare Pediatric Disease Designation and Orphan Drug Designation with preparations for its clinical development underway. AVG-001 is designed to promote localised production of alpha-1 antitrypsin in the lung to treat patients with Alpha-1 Antitrypsin Deficiency (AATD) lung disease from a single treatment providing an alternative to standard-of-care therapy (weekly IV protein replacement). Preparations for clinical development are underway. AlveoGene was founded in 2023 by Oxford Science Enterprises, Harrington Discovery Institute and Old College Capital in partnership with six leading scientists from the world-renowned UK Respiratory Gene Therapy Consortium (GTC). It is the first company being advanced under the Oxford-Harrington Rare Disease Centre’s Therapeutics Accelerator. The UK Respiratory Gene Therapy Consortium (GTC) comprises world-leading researchers at Imperial College London and the Universities of Oxford and Edinburgh who have worked together for more than 20 years with a focus on translating gene therapy for respiratory diseases. The GTC developed the novel pseudotyped lentiviral vector, which underpins AlveoGene’s InGenuiTy® platform and pipeline, and which is relevant to both Cystic Fibrosis (licensed to and now being developed by Boehringer Ingelheim in the Lenticlair™ clinical trial) and multiple rare and other lung conditions.

David Hipkiss, Executive Chair of AlveoGene, said: “This Rare Pediatric Disease Designation (RPDD) for AVG-002 marks a significant step forward in our mission to develop transformative treatments for children with fatal genetic lung diseases. Receiving this RPDD not only underscores the urgent need for innovative therapies in this area but also highlights the potential of our approach in SP-B deficiency in newborn infants, which is designed to target the affected lung tissues directly, restore vital function and provide a viable therapeutic solution where presently there is none. “We similarly expect exciting results with AVG-003, our programme in ABCA-3 deficiency, also a life-threatening rare pediatric genetic respiratory disorder, but with 3-5 times greater incidence than SP-B deficiency. AVG-003 leverages the same novel InGenuiTy® platform technology as AVG-002, and we are optimistic that it might also meet the criteria for an RPDD as we advance its development. “In addition, our excellent preclinical progress with AVG-001 for patients with lung disease as a consequence of Alpha-1 Antitrypsin Deficiency (AATD), continues to give us confidence that it could become a best-in-class treatment that targets the lung directly where its impact on morbidity and mortality is highest and patient numbers are the greatest.” Rare pediatric diseases are defined by the FDA as serious or life-threatening conditions primarily affecting children under 18, with fewer than 200,000 cases in the US. Companies awarded an RPDD receive a rare pediatric disease Priority Review Voucher (PRV) from the FDA when the designated drug is approved for the associated indication in the pediatric population. The voucher allows the recipient company to obtain FDA priority review of either a New Drug Application (NDA) or Biologics License Application (BLA) for a different product and/or indication, reducing the review time and accelerating any granted approval and subsequent market entry by at least four months. The PRV may be used by the original recipient, or it can be sold to another company for the purchaser’s use, with PRVs recently achieving sales prices of $100-$150 million. Executive Chair, David Hipkiss, will present an overview of AlveoGene and its innovative technology and pipeline at the Inv€$tival Showcase on Monday 19 November at 15.00 hrs GMT at the Tobacco Dock in London, UK.

- Heart of Genetic Counseling Award recognizing excellence in patient care will be presented by Invitae and NSGC - SAN FRANCISCO, Nov. 10, 2022 /PRNewswire/ -- Researchers from Invitae (NYSE: NVTA), a leading medical genetics company, are presenting research next week at the National Society of Genetic Counselors (NSGC) 41st Annual Conference in Nashville enabling the progress of the science and practice of genetics in patient care. In addition to its research presentations, the company will present the Heart of Genetic Counseling Award, which recognizes excellence in the field of genetic counseling. The company's research presentations, which include a pre-conference symposium, opening plenary, sponsored session and poster presentations, add to both the science and practice of the fast-growing field of medical genetics. Among the company's poster presentations is a retrospective case-control study aimed to assess the cancer risk for individuals who have a monoallelic MUTYH pathogenic/likely pathogenic variant. In addition, Invitae will present a study highlighting how RNA sequencing can help classify variants predicted to alter RNA splicing, as well as uncovering splice-altering variants in regions outside of the standard reportable range of targeted DNA panels. "The NSGC annual meeting is a great opportunity for Invitae to show our continued commitment to genetic counselors and their patients as well as furthering the science behind genetic testing," said Robert Nussbaum, M.D., chief medical officer at Invitae. "Working with genetic counselors, we continue to champion affordability, accessibility and innovation – so that we can find answers for more patients, together." Heart of Genetic Counseling Award In addition to the research presentations at the meeting, Invitae and NSGC will present the 2022 Heart of Genetic Counseling Award in a ceremony at the NSGC Annual Conference. The Heart of Genetic Counseling Award was established to honor excellence in genetic counseling patient care as recognized by patients themselves. Nominations include stories from patients that highlight both the clinical and personal impact a genetic counselor had on their lives and the lives of their families. The finalists include: Monisha Sebastin, MS, CGC, Children's Hospital at Montefiore Medical Center, The Bronx, New York, was nominated by a parent whose daughter has fanconi anemia (FA), a rare genetic disease that affects the bone marrow. When the daughter was diagnosed with COVID, Sebastin went above and beyond to get her treatment by arranging for her infusions within a few hours which was critical given the daughter's pulmonary issues and compromised immune system. Victoria Vincent, MS, CGC, University of South Carolina, Columbia, South Carolina, showed true compassion for a patient who lost several children due to surfactant protein-B (SP-B) deficiency, a rare lung disorder that causes most babies to die within the first few weeks of life. Vincent provided the patient with emotional support during her losses and, after many years, celebrated with the patient when they discovered that her son and his fiancée did not carry the SP-B mutation. Julianne Wojciak, MS, LGC, University of California, San Francisco, California, counseled a patient during her testing for the LMNA genetic mutation, which can cause cardiac arrest or heart failure. Due to the diagnosis, the patient received an internal cardiac monitor, which detected pauses in her heart activity that saved her life. Wojciak also supported the patient through the process of testing her children for the LMNA mutation. The Heart of Genetic Counseling Award will be presented on Thursday, November 17.
