Trial Outcomes & Findings for Bevacizumab and/or Niraparib in Patients With Recurrent Endometrial and/or Ovarian Cancer With ARID1A Mutation (NCT NCT05523440)
NCT ID: NCT05523440
Last Updated: 2026-06-03
Results Overview
To estimate the proportion of patients with objective tumor response (complete or partial), to the combination treatment of niraparib and bevacizumab and to monotherapy niraparib.
TERMINATED
PHASE2
9 participants
16 months, until early study termination
2026-06-03
Participant Flow
Nine subjects were accrued on the study at the University of Oklahoma and at the University of Virginia Arlington.
Of the 9 subjects accrued, there were 2 screenfails and 7 subjects who were eligible to start treatment. Of the 7 subjects, 4 were randomized to Arm 1 with niraparib only, and 3 were randomized to Arm 2 with niraparib and bevacizumab.
