Detailed Description
This is a single-arm two-stage phase II study of PD-1 inhibitor zimberelimab (AB122) in combination with TIGIT inhibitor domvanalimab (AB154) in advanced melanoma patients who have failed PD-1 inhibitor therapy.
Patients will undergo a 28-day screening evaluation consisting of systemic staging scans, tumor biopsy, and blood studies to confirm suitability. Once enrolled, patients will receive zimberelimab 360 mg every 3 weeks (Q3W) and domvanalimab 15 mg/kg Q3W. Patients will undergo restaging scans at W9 following 3 cycles of therapy with response assessed using RECIST v1.1 and iRECIST. Following restaging scans, patients with response will continue to receive zimberelimab and domvanalimab till disease progression, intolerable toxicity or for up to 24 months.

- Male participants: A male participant must agree to use a contraception during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.
Female participants: A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
- Not a woman of childbearing potential (WOCBP); OR
- A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 120 days after the last dose of study treatment.
Participants must have progressed on treatment with an anti-PD-1/L1 mAb administered either as monotherapy or in combination with other checkpoint inhibitors or other therapies. PD-1 treatment progression is defined by meeting all of the following criteria:
