This study will evaluate the safety, tolerability, anti-tumor activity, immunogenicity, pharmacokinetics and pharmacodynamics of the IKS04 Regimen and identify a recommended phase 2 dose (RP2D) or recommended dose for further evaluation in expansion (RDE). The regimen includes Isumab04 (unconjugated antibody) followed by the IKS04 antibody-drug conjugate, both directed against the CA242 (CanAg) tumor-associated antigen and administered intravenously (IV) in patients with advanced solid cancers.
The study will consist of 2 parts: dose-escalation (Part I) and dose-expansion (Part II). The dose-escalation part (Part I) will evaluate the safety and tolerability of increasing dose levels of the IKS04 Regimen and to establish a RP2D and/or a RDE; and the dose-expansion portion (Part II) of the study will further characterize the safety, pharmacokinetics/pharmacodynamics, and efficacy of the IKS04 Regimen at the RP2D or RDE. Participants may continue on study until disease progression, unacceptable toxicity, or other withdrawal criteria is met.
Key Inclusion Criteria: * Advanced or metastatic CRC, BTCs, GEA, and PDAC that is histologically or cytologically confirmed * Disease that has progressed despite prior treatment, for which additional effective therapy is not available, not tolerable, is contraindicated, or the participant refuses standard therapy. * Platelets ≥ 100,000 /mcL * Hemoglobin ≥ 9.0 g/dL., no transfusions with RBCs are allowed within 2 weeks prior to first trial drug administration * ANC ≥ 1500/mcL * Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (s…
