This is an open label, multi-center trial of tisotumab vedotin monotherapy and in combination with bevacizumab, pembrolizumab, or carboplatin in subjects with recurrent or stage IVB cervical cancer.
The trial consists of two-parts a dose escalation part and an expansion part. The expansion part of the trial will be initiated once the Recommended Phase 2 Dose (RP2D) of the combinations have been determined in the dose escalation part.
Condition or disease | Intervention/treatment | Phase |
---|---|---|
Cervical Cancer | Drug: Tisotumab Vedotin Drug: Bevacizumab Drug: Pembrolizumab Drug: Carboplatin | Phase 1 Phase 2 |
The dose escalation part will occur in cervical cancer subjects who have progressed during or after standard of care therapy and who are intolerant or ineligible to receive standard of care treatments. Arm A will be conducted by escalating doses of both tisotumab vedotin and bevacizumab. Dose escalations of the tisotumab vedotin + pembrolizumab and tisotumab vedotin + carboplatin combinations (Arms B and C, respectively) will be conducted by combining fixed doses of either pembrolizumab or carboplatin with increasing doses of tisotumab vedotin.
The dose expansion part will consist of subjects with recurrent or stage IVB cervical cancer, who have not received prior systemic therapy for their recurrent or stage IVB disease, Arms D and E being treated with tisotumab vedotin + carboplatin or tisotumab vedotin + pembrolizumab, respectively, or subjects, who have progressed on or after standard of care treatments, Arm F treated with tisotumab vedotin + pembrolizumab and Arm G treated with tisotumab vedotin alone. Subjects enrolled to Arms D, E, and F will receive the RP2D of tisotumab vedotin established in the dose escalation part. Subjects enrolled to Arm G will receive tisotumab vedotin weekly for three weeks and 1 week off (28 day treatment cycle).
