About the study

This is a first-in-human, Phase 1, multicenter, open label, single arm, integrated 3-part dose escalation and dose expansion study designed to evaluate the safety, tolerability, PK, immunogenicity, pharmacodynamics, and preliminary antitumor activity of AK117 administered intravenously to adult subjects with relapsed/refractory advanced or metastatic solid tumors or lymphomas.

  14. Adequate organ function.

EXCLUSION CRITERIA

All Subjects
