Efficacy and Safety Study of Acasunlimab as Monotherapy and in Combination With Pembrolizumab in Subjects With Relapsed/Refractory, Unresectable Locally Advanced or Metastatic Cutaneous Melanoma That Progressed On or After Treatment With a Checkpoint Inhibitor (ABBIL1TY MELANOMA-07)
The goal of this clinical trial is to learn about the effectiveness and safety of the bispecific antibody acasunlimab (also known as DuoBody®-PD-L1x4-1BB) when given either alone or together with the cancer drug pembrolizumab in participants with locally advanced or metastatic melanoma of the skin. All participants will receive active drugs; no one will be given a placebo. The trial duration will be approximately 15 months for each participant, including a 28-day screening period and estimated 4-month treatment and 10-month follow-up periods; however, the duration of the treatment and follow-up periods may vary for each participant. Participants will have regular check-ups while on treatment, with visits every week initially, and then every 3 weeks later in the trial.
• Participants ≥ 18 years of age with histologically or cytologically confirmed diagnosis of relapsed/refractory, locally advanced unresectable (Stage IIIB, IIIC, or IIID) or metastatic (Stage IV) cutaneous melanoma, per American Joint Committee on Cancer (8th edition) staging.
• Participant must have radiographic progression based on RECIST v1.1 on or following ≥ 1 prior systemic therapy, according to local and international guidelines, including a programmed cell death protein 1 blocking antibody (anti-PD-1) treatment or combination treatment containing an anti-PD-1.
• Participant must have received a minimum of 2 cycles of an approved anti-PD-1 as monotherapy or a combination therapy containing an anti-PD-1.
• Neoadjuvant and/or adjuvant systemic therapy count as the first line of prior systemic therapy if there is documented disease progression ≤ 6 months after completion of therapy.
• Participants with a BRAF V600 mutation should have received prior BRAF-directed therapy (with or without a MEK inhibitor) prior to enrollment in the trial, unless deemed not clinically indicated by the Investigator due to concurrent medical condition or prior toxicity.
• Participant has an Eastern Cooperative Oncology Group performance status of 0 or 1 within 7 days prior to Cycle 1 Day 1.
