No
If Stopped, Why?:
The INHIBIT Trials IDSMB, in a letter dated 05-18-22, recommended, given the slow enrollment, that the INHIBIT Trials be discontinued due to futility.

Brief Summary:
This is a multi-center randomized phase III clinical trial, the Inhibitor Prevention Trial, in which Eloctate will be compared with Emicizumab, using adaptive design, to prevent inhibitors in patients with severe hemophilia A.
Detailed Description:
This is a multi-center randomized phase III clinical trial, the Inhibitor Prevention Trial, in which consecutive hemostatic agents will be compared using adaptive design to prevent inhibitors in patients with severe hemophilia A. This adaptive design is necessary as randomized trials in rare diseases are otherwise not possible. This adaptive design is necessary as randomized trials in rare diseases are otherwise not possible. The INHIBIT Clinical Trials Platform includes two linked trials, the Inhibitor Prevention Trial (Prevention Trial) and the Inhibitor Eradication Trial (Eradication Trial) that will be conducted at up to 41 U.S. hemophilia treatment centers (HTCs) affiliated with universities. The Inhibitor Prevention Trial is a 48-week randomized phase III trial, in which 66 previously untreated patients (PUPs) with severe hemophilia A will be enrolled. Subjects will include children from 4 months of age up to 4 years of age who have not been previously treated with clotting factor. Once enrolled, subjects who meet all the inclusion and none of the exclusion criteria will be randomized to preemptive weekly Eloctate (rFVIIIFc) vs. weekly Emicizumab (Hemlibra) to prevent inhibitor formation, defined as anti-FVIII \>= 0.6 BU. Blood draws will be minimized to 6 timepoints, pre, 4, 12, 24, 36, and 48 weeks, and validated for small volumes, 3.8 cc (¾ tsp) each. The Inhibitor Prevention Trial is considered greater than minimal risk as study drug is given before the first bleed and special inhibitor studies are obtained. (NB: The Inhibitor Prevention Trial (PRO19040140) is linked to the Inhibitor Eradication Trial (PRO19070080), as part of the INHIBIT Clinical Trials Platform, with both trials will be conducted efficiently in the same hemophilia treatment centers (HTCs), with the same MDs, coordinators, visit frequency, blood sampling, and assays.
