Summary

HWK-016-101 is a multicenter, open-label, first-in-human (FIH) Phase 1 study evaluating HWK-016, a targeted antibody-drug conjugate (ADC) in adult participants with advanced or metastatic solid tumors. The study employs a dose escalation and dose expansion design without a control group. The study consists of 2 parts (Part A: monotherapy and Part B: combination therapy with bevacizumab); each part has 2 phases, Phase 1a (dose escalation) and Phase 1b (dose expansion). Enrollment to Part A (Phase 1a and Phase 1b) will include ovarian and endometrial cancers. Enrollment to Part B (Phase 1a and Phase 1b) will include ovarian cancer only. A subsequent protocol amendment may evaluate additional tumor types.
