Key Clinical Program Updates
FLT180a in Hemophilia B – On track to fully enroll Phase 1/2 B-LIEVE dose confirmation study by the end of the third quarter of 2022, enabling initiation of pivotal Phase 3 study start-up activities in H1 2023.
- Potential for FLT180a to provide functional cure through durable normalization of Factor IX activity (50-150%) demonstrated in the long-term follow-up study of the Phase 1/2 dose-finding trial, B-AMAZE. Data demonstrating sustained FIX expression up to 3.5 years and decline in annualized exogenous Factor IX consumption and bleeding after gene therapy reported at the 63rd American Society of Hematology (ASH) Annual Meeting in December 2021.
- B-LIEVE study currently underway to confirm 7.7e11 vg/kg dose and prophylactic immune management to be used in pivotal Phase 3 study. The first patient in the B-LIEVE study was dosed in March 2022, with completion of the first dose cohort and reporting of initial data both expected in the first half of 2022.
FLT190 in Fabry Disease – Updated clinical development plan and timelines for Phase 1/2 MARVEL-1 study accelerates dose escalation to mid-year 2022.
- Following a comprehensive review of the pre-clinical data and the efficacy and safety data generated to date in the MARVEL-1 study with the study’s independent Data Monitoring Committee, the Company plans to proceed immediately to the second dose cohort (1.5e12 vg/kg).
- The Company expects to dose the first patient in the second dose cohort in mid-2022 and provide a program update in the second half of 2022.
- Reported data from the lowest dose cohort in MARVEL-1 trial, demonstrating durable α-Gal A expression over two years in the first patient and promising activity with near-normal α-Gal A levels in the second patient, who was dosed in June 2021 and remained off enzyme replacement therapy for more than 26 weeks post-dosing, as of the last data cut-off date of December 22, 2021.
FLT201 in Gaucher Disease – On track to dose patients in first-in-human, Phase 1/2 GALILEO-1 study in H1 2022.
- Phase 1/2 GALILEO-1 study initiated at the end of 2021, and study design presented at the 18th annual WORLD Symposium™, February 7-11, 2022.
- The Company expects to dose two patients in the first dose cohort in the first half of 2022 and two patients in the second cohort in the second half of 2022, with initial data from such patients expected in the second half of the year.
- GALILEO-1 is a first-in-human open-label, international, multicenter clinical study evaluating the safety, tolerability, and efficacy of a single intravenous infusion of FLT201 with a novel prophylactic immune management regimen in adults with Gaucher disease Type 1.
- Adaptive dose-escalation study will identify a dose of FLT201 for further development in a pivotal Phase 3 clinical trial.
- FLT201 consists of a rationally designed AAV capsid (AAVS3) containing an expression cassette that encodes for a novel glucocerebrosidase variant (GCasevar85) under the control of a liver-specific promotor.
