A Study of KIVU-107 in Participants With Locally Advanced or Metastatic Solid Tumors

A Phase 1 Dose-Finding and Dose-Expansion Study of KIVU-107 in Participants With Locally Advanced or Metastatic Solid Tumors

This is a 2-part, first-in-human, open-label study to determine the safety and tolerability of KIVU-107, a PTK7-directed antibody-drug conjugate, in participants with locally advanced or metastatic solid tumors.

Part A: The primary objective of Part A of this study is to evaluate the safety and tolerability of KIVU-107 and to determine the maximum tolerated dose (MTD)/Recommended Dose for Expansion (RDE).

Part B: The primary objective of Part B of this study is to confirm the safety and tolerability of KIVU-107 at the RDE.

Inclusion Criteria:

• Male or female ≥18 years of age

• Adequate bone marrow, kidney, and liver function
• Measurable disease using RECIST v1.1
• ECOG 0 or 1
• Life expectancy ≥ 3 months

Exclusion Criteria:

• Prior treatment with any ADC with topoisomerase 1 inhibitor payload
• Any PTK7 - targeted therapy
• Uncontrolled cardiovascular disease
• Active Hepatitis B, Hepatitis C, or HIV infection
• History of interstitial lung disease
• Major surgery, radiation therapy, or systemic anti-cancer within 3 weeks of study treatment start.
