Metastatic Melanoma | Drug: ADU-1604 | Phase 1 |
ADU-CL-17 is a first-in-human, open-label, multicenter, dose-escalation study designed to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of ADU-1604, an anti-CTLA-4 monoclonal antibody, and explore initial clinical activity in adults with metastatic melanoma. The primary objective of the study is to determine the Recommended Phase 2 Dose (RP2D) of ADU-1604 administered by IV infusion once every 3 weeks for 4 doses.
The study will be conducted in two parts: Dose Escalation followed by Dose Confirmation.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Male or female aged ≥18 years
- Histologically-confirmed metastatic or unresectable melanoma
- Progression of disease following at least one prior therapy, and is not a candidate for, or is intolerant to, established therapy known to provide clinical benefit (i.e. available treatment options have been exhausted). Subjects must have BRAF mutation status confirmed; if a subject is BRAF V600E/K positive, they must have received a BRAF- targeted regimen prior to entering the study, unless the patient was deemed ineligible for such treatment
- Measurable disease according to RECIST (v1.1) [NOT required during Dose Escalation]
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
Exclusion Criteria:
- Prior diagnosis of uveal or mucosal melanoma
- Prior treatment with CTLA-4-directed therapy in the metastatic setting. Use of CTLA- 4-directed treatment in the adjuvant or neoadjuvant setting is acceptable provided the last dose was >6 months before the first dose of ADU-1604 and there was no discontinuation of treatment due to a treatment-related toxicity.
