First-in-Human, Open-Label, Safety, Tolerability, Dose-Finding, Pharmacodynamic and Cardiac Transgene Expression Study of TN-201, a Recombinant Adeno-associated Virus Serotype 9 (AAV9) Containing Myosin Binding Protein C Transgene, in Adults With MYBPC3 Mutation-associated Hypertrophic Cardiomyopathy (HCM)

Tenaya Therapeutics

Summary

This is a first-in-human, non-randomized, open-label study designed to evaluate the safety, tolerability, and pharmacodynamics (PD) of TN-201 in adult patients with symptomatic hypertrophic cardiomyopathy (HCM) caused by mutations in the MYBPC3 gene.

Description

The study will consist of 2 escalating dose cohorts (groups). The study will enroll at least 6 and as many as 30 patients. All patients will receive active drug (TN-201 Gene Therapy). The study will follow patients for 5 years following a single dose of TN-201.

Eligibility

Age range: 18–75 years
Sex: All
Healthy volunteers: No

Detailed criteria

Inclusion Criteria: * MYBPC3 mutation * Hypertrophic Cardiomyopathy (obstructive and nonobstructive) * Left Ventricular Ejection Fraction ≥45% * NYHA Functional Class II or III symptoms * NT-proBNP ≥160pg/ml Exclusion Criteria: * High AAV9 neutralizing antibody titer
