Clinical Trial Summary

Phase 2, multi-center, open-label study designed to evaluate the PK, bioavailability, PD, efficacy and safety of a daily subcutaneous [SC] treatment regimen with MarzAA for bleeding prophylaxis in 12 adult subjects with hemophilia A or B with an inhibitor and history of frequent spontaneous bleeding episodes.


Clinical Trial Description

Multi-center, open-label Phase 2 study to evaluate the PK, bioavailability, PD, efficacy and safety of a daily SC treatment regimen with MarzAA for bleeding prophylaxis in adult subjects with hemophilia A or B with an inhibitor. The study will enroll and dose, both intravenously and subcutaneously, a total of 12 adult male subjects with severe congenital hemophilia A or B with an inhibitor, and history of frequent bleeding episodes during the 6 months prior to enrollment, as per the individual's bleeding and treatment records. Once a subject is enrolled into the trial, the study will be conducted in three parts (occurring consecutively): Part 1a (24 hours): Single IV administration of MarzAA; Part 1b (48 hours): Single SC administration of MarzAA; Part 2: Daily SC administration. Dose escalation in Part 2 will occur if breakthrough bleeding occurs. Subjects are treated for 50 days at the final dose level required. ;
