The three Milvexian indications BMY/JNJ are pursuing in phase-3 are: secondary stroke prevention; ACS; and primary stroke prevention in patients with AF—see #msg-171338375.
FDA Fast Track status doesn’t mean much, but it makes a Priority Review of the NDAs somewhat more likely (if one or more of these phase-3 trials pan out).
Two other phase-3 Milvexian trials continue: primary stroke prevention in patients with atrial fib; and secondary stroke prevention following a stroke or TIA.
Milvexian’s phase-2 data were murky (#msg-169809402), so this phase-3 program was relatively high-risk. It may turn out that FXIa is not a better place to intervene in the coagulation cascade than FXa. This is plainly what PFE thought when PFE declined to partner with BMY on an FXIa “successor” to Eliquis.
