(NASDAQ: BMRN), a global biotechnology company dedicated to transforming lives through genetic discovery, today announced positive results from more than three years of follow up from its ongoing global Phase 3 GENEr8-1 study of ROCTAVIANTM (valoctocogene roxaparvovec), an investigational one-time gene therapy for the treatment of adults with severe hemophilia A. This is the largest and longest global Phase 3 study to date for any gene therapy in hemophilia with 134 participants.
The ROCTAVIAN data are summarized in the following table:
Phase 3 (6e13 vg/kg dose) | |||
In Year 3* | In Year 4** | ||
FVIII Activity (chromogenic) | Mean | 18.8 | 15.2 |
Median | 8.4 | 7.4 | |
Annualized Bleeding Rate*** (bleeding episodes per year) | Mean | 1.0 | 0.8 |
Median | 0.0 | 0.0 | |
Annualized FVIII Utilization (infusions per year) | Mean | 8.4 | 11.1 |
Median | 0.0 | 0.0 | |
*N=132 (FVIII Activity); N=112 (ABR and AFR). Two of these patients discontinued from the study prior to reaching Year 3. FVIII imputed to be 0 IU/dL; no imputation was carried out for ABR and AFR. **N=17. One of these patients discontinued from the study prior to reaching Year 4. FVIII activity imputed to be 0 IU/dL; no imputation was carried out for ABR and AFR. ***Annualized rate is for treated bleeds. | |||
