A Phase 1b/2 Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Mirvetuximab Soravtansine (IMGN853) in Combination With Bevacizumab, Carboplatin, Pegylated Liposomal Doxorubicin, Pembrolizumab, or Bevacizumab + Carboplatin, in Adults With Folate Receptor Alpha Positive Advanced Epithelial Ovarian Cancer, Primary Peritoneal Cancer, or Fallopian Tube Cancer
In Brief
A Phase 2 clinical trial evaluating Mirvetuximab soravtansine, Bevacizumab, and 3 other interventions for Epithelial Ovarian Cancer and 2 related conditions. Completed, enrolled 264 participants across 12 sites in 4 countries.
Detailed Summary
This study comprises a Dose Escalation phase followed by a Dose Expansion phase. Dose Escalation part of the study will assess the safety and tolerability and determine the maximum tolerated dose (MTD) as the recommended Phase 2 (RP2D) dose for each regimen. Participants will be assigned to one of the 4 regimens in Dose Escalation phase: Regimen A: mirvetuximab soravtansine administered with bevacizumab; Regimen B: mirvetuximab soravtansine administered with carboplatin; Regimen C: mirvetuximab soravtansine administered with pegylated liposomal doxorubicin; or Regimen D: mirvetuximab soravtansine administered with pembrolizumab. Dose Expansion of the study will further assess safety, tolerability and preliminary anti-tumor activity of mirvetuximab soravtansine. A Dose Expansion phase is planned for Regimen A and Regimen D and will open pending Sponsor decision; participants enrolled in the Dose Expansion phase will receive study treatment at the MTD or RP2D determined during Dose Escalation. For Regimen A, participants in the Dose Expansion phase may be enrolled according to prior exposure to bevacizumab into 3 Dose Expansion Cohorts as follows: 1) Dose Expansion Cohort 1: bevacizumab naïve; 2) Dose Expansion Cohort 2: bevacizumab pretreated; and 3) Dose Expansion Cohort 3: one to three prior treatments, one of which could have been bevacizumab. A triplet Regimen (Regimen E: mirvetuximab soravtansine + bevacizumab + carboplatin) will be opened to evaluate the safety and tolerability and to assess any early signs of activity in participants dosed with the combination regimen. All mirvetuximab soravtansine doses were calculated according to adjusted ideal body weight.
