Phase 1B Study of AV-380 Combined with Standard Chemotherapy in Adults with Metastatic Cancer and Cachexia with High GDF-15 Levels

What this Trial Is About

Researchers are evaluating AV-380, an immunoglobulin G1 monoclonal antibody designed to bind human growth differentiation factor 15 GDF-15, a cytokine involved in cancer-induced cachexia. This phase 1B open-label dose escalation study aims to assess the safety, pharmacokinetics, pharmacodynamics, and immunogenicity of AV-380 in cancer patients who have cachexia and elevated GDF-15 levels. Participants have metastatic solid tumors and are actively receiving standard of care chemotherapy. Participants receive AV-380 through intravenous infusion in ascending dose cohorts alongside their standard chemotherapy treatments. The study includes a dose escalation phase where the safety and appropriate dosage of AV-380 are evaluated. This phase allows researchers to monitor the effects of increasing doses of AV-380 over a study period of up to 4 months while patients continue their usual cancer therapies. During the study, participants will undergo assessments including monitoring for adverse events, toxicity, and laboratory abnormalities from enrollment until about 60 days after the last dose. Pharmacokinetic measures such as maximum concentration Cmax, time to maximum concentration Tmax, and area under the curve AUC will also be evaluated. The total involvement includes regular evaluations to track safety, drug behavior in the body, and immune responses to AV-380.
