Focus areas at Regenxbio

As a rare disease specialist, Regenxbio has active clinical trial programs and drug development efforts across 6 rare diseases, including Batten Disease, Duchenne Muscular Dystrophy, Geographic Atrophy, Homozygous Familial Hypercholesterolemia, Hunter Syndrome, and 1 additional rare conditions. These programs may span orphan drug designation, novel therapeutic mechanisms, and precision medicine approaches targeting the underlying causes of each disease.

The clinical trials section below shows active and recruiting rare disease studies sponsored by Regenxbio, sourced live from ClinicalTrials.gov. Each trial includes its current recruitment status, study phase (Phase 1 through Phase 4), conditions under investigation, and the number of active trial sites. The FDA-approved drugs section lists treatments that have received U.S. Food and Drug Administration approval, with brand names, generic names, approval dates, and matched rare disease indications from the openFDA database.

Regenxbio is headquartered in Rockville, United States, founded in 2009, publicly traded under the ticker symbol RGNX. The company dedicates its research and development resources exclusively to rare and orphan diseases, working to bring innovative treatments to patients with conditions that have historically had limited or no treatment options.

Regenxbio Drug Pipeline

Regenxbio has 4 active clinical trials across 2 development stages. Clinical trials advance through phases: Phase 1 tests safety in a small group, Phase 2 evaluates effectiveness and side effects, Phase 3 confirms benefit in a larger population, and Phase 4 monitors long-term safety after FDA approval.

Note: This pipeline counts the active and recruiting trials listed on this page, from ClinicalTrials.gov. For companies that work outside rare disease, we list only trials for rare diseases we track, so the company's full pipeline may be larger.

AFFINITY DUCHENNE: RGX-202 Gene Therapy in Participants With Duchenne Muscular Dystrophy (DMD)

Intervention: RGX-202

RGX-202 is a gene therapy designed to deliver a transgene for a novel microdystrophin that includes functional elements of naturally-occurring dystrophin including the C-Terminal (CT) domain. This is a multicenter, open-label dose evaluation clinical study to assess the safety, tolerability, and clinical efficacy of a one-time intravenous (IV) dose of RGX-202 in participants with Duchenne.

RGX-121-3102 Gene Therapy in Participants With MPS II (Hunter Syndrome)

Intervention: RGX-121-3102

RGX-121 is a gene therapy which is intended to deliver a functional copy of the iduronate-2-sulfatase gene (IDS) to the central nervous system. This study is a safety, efficacy, and pharmacodynamic dose ranging study to determine whether RGX-121 is safe, effective and well-tolerated by patients with MPS II (Hunter Syndrome)

Rare Disease Focus Areas (6)

Diseases targeted by Regenxbio's clinical trial and drug development programs

Batten DiseaseNeurological & Neuromuscular

Batten disease is a rare inherited neurological disorder caused by mutations in genes affecting lysosomal function, leading to accumulation of lipofuscin (age pigment) in neurons. Progressive vision l...

Prevalence: Approximately 2-4 per 100,000 births in the U.S.; higher in certain populations (e.g., northern Europe)
Duchenne Muscular DystrophyNeurological & Neuromuscular

Duchenne muscular dystrophy is an X-linked genetic disorder causing progressive muscle weakness and degeneration, beginning in early childhood. The defective dystrophin protein normally protects muscl...

Homozygous Familial HypercholesterolemiaCardiovascular

Homozygous Familial Hypercholesterolemia is a severe genetic disorder causing extremely high cholesterol levels from birth, leading to early heart disease and cholesterol deposits in tendons and aroun...

Prevalence: Approximately 1 in 250,000 to 1 in 360,000 people globally
Hunter SyndromeMetabolic & Lysosomal
