Carbon Biosciences is a Waltham, Massachusetts preclinical genetic-medicine company building gene therapies on non-AAV parvovirus vectors. Founded by Longwood Fund with gene-therapy pioneers John Engelhardt and Robert Kotin, it uses a proprietary vector engine (PAVE) to design capsids from the broad parvovirus family - including human bocavirus - that carry larger genetic payloads, target specific tissues, and provoke little pre-existing immunity, opening the door to re-dosing. Its lead program targets cystic fibrosis by delivering the full-length CFTR gene to the lung, with a second vector aimed at cardiac disease.
Joel Schneider is the founder, president and CEO of Carbon Biosciences, a Waltham, Massachusetts biotech building gene therapies from parvovirus-derived vectors rather than the more common adeno-associated viruses. He launched the company out of stealth in 2022 with a $38 million Series A led by Agent Capital, pairing his operating background with the science of gene therapy pioneer Robert Kotin. Trained as a stem cell biologist with a Rutgers Ph.D. and a Harvard postdoc, Schneider was the first employee at Solid Biosciences before founding Carbon to push vectors that carry larger genetic payloads, target specific tissues such as the lung, and sidestep the pre-existing immunity that limits current gene therapies. Carbon's lead program targets cystic fibrosis.
KaliVir Immunotherapeutics is a clinical-stage biotech developing next-generation oncolytic viral immunotherapies for cancer. Its proprietary Vaccinia Enhanced Template (VET) platform engineers vaccinia viruses that can be delivered intravenously, replicate selectively in tumors, and express therapeutic payloads that reshape the tumor microenvironment. Founded in 2019 and headquartered in Pittsburgh, the company advances an internal lead candidate, VET3-TGI, alongside partnered programs licensed to Astellas Pharma and Roche.
Tuyen Ong is a physician-turned-biotech executive who spent four years as CEO of Ring Therapeutics, the Flagship Pioneering company trying to turn anelloviruses - harmless viruses that already live in nearly everyone - into a redosable delivery system for genetic medicines. Trained as an ophthalmologist at University College London with an MBA from NYU Stern, he built his career on gene therapy for rare eye disease at Nightstar, Biogen, PTC, Bausch & Lomb and Pfizer before betting on a virus most scientists had written off as biological junk. In 2025 he co-founded PharmasMarket, a drug-development consultancy.
GEMMA Biotherapeutics (GEMMABio) is a Philadelphia-based gene therapy company spun out of the University of Pennsylvania and founded by AAV pioneer James M. Wilson. Launched in October 2024 with $34 million in seed funding, GEMMABio builds the research, manufacturing, and product-development infrastructure to move adeno-associated virus (AAV) gene therapies from the bench to the bedside faster and more affordably - with a focus on rare and ultra-orphan inherited diseases and a stated commitment to global patient access.
Ramon Salsas Escat is the Chief Business Officer of GEMMA Biotherapeutics (GemmaBio), the Philadelphia gene-therapy company spun out of Jim Wilson's lab to widen global access to AAV therapies for rare inherited diseases. A chemist by training who earned a PhD in computational and systems biology at MIT and an MBA at IESE, Salsas has led or co-led more than 20 transactions across AAV gene therapies, CNS disorders, oncology and manufacturing platforms, with cumulative deal value north of $4 billion in upfront payments and milestones. He helped build the business engine at Penn's Gene Therapy Program, served as SVP of Business Development at G2 Bio, and now runs business development, alliance management, legal and IP at GemmaBio, where he played a pivotal role in the company's founding and its $34 million seed round.
克睿基因 Cure Genetics is a clinical-stage biotech founded in Suzhou in 2016 that develops cell and gene therapies for solid tumors and genetic diseases. It runs two proprietary platforms: AIMS, an allogeneic CAR-NKT cell therapy approach aimed at hard-to-treat solid tumors, and VELP, a directed-evolution AAV vector platform that builds high-quality viral libraries for tissue-targeted gene delivery to the nervous system, heart, and kidney. Its lead programs include CGC729 (anti-CD70 CAR-NKT for renal cell carcinoma) and CGC-602 (a PD-1-IL-2v bispecific antibody).
