Gene therapy

AVROBIO · Phase 2 active Small molecule ✓ Verified May 2026 Quality 35/100

Gene therapy is a Gene Therapy Small molecule drug developed by AVROBIO. It is currently in Phase 2 development. Also known as: AVR-RD-02, therapy, gene, Intracerebral infusion of AAV2-hAADC viral vector, CD68-ET3-LV CD34+.

Introduces functional genetic material into patient cells to correct underlying genetic defects or provide therapeutic benefit.

Gene therapy is a medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells. It has been studied for various conditions, including Adenosine Deaminase Severe Combined ImmunoDeficiency (ADA-SCID), Diabetic Macular Edema, Diabetic Retinopathy, Acute Promyelocytic Leukemia, and Pompe Disease, using gene-based interventions such as lentiviral vectors.

Likelihood of approval
15.3% vs 15.3% industry baseline
If approved by FDA: likely 2031–2034
Steps remaining: Phase 3 → NDA/BLA submission
Confidence: Medium
Why this estimate
  • Baseline phase 2 → approval rate +15.3pp
    Industry-wide phase 2 drugs reach approval ~15.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2031–2034
EMA EU 2032–2035 +0.7 yr
MHRA GB 2032–2035 +0.7 yr
Health Canada CA 2032–2036 +0.9 yr
TGA AU 2032–2036 +1.2 yr
PMDA JP 2032–2036 +1.5 yr
NMPA CN 2033–2037 +2.3 yr
MFDS KR 2032–2036 +1.4 yr
CDSCO IN 2032–2037 +1.8 yr
ANVISA BR 2033–2037 +2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.

Mechanism of action

Gene therapy delivers DNA or RNA sequences into target cells to replace defective genes, introduce new therapeutic genes, or modify gene expression. The approach aims to address the root cause of genetic diseases rather than treating symptoms.
