A Phase 1/2 Study of PRO1107 in Patients With Advanced Solid Tumors


  • Org Study ID: PRO1107-001
  • Secondary ID: N/A
  • NCT ID: NCT06171789
  • Sponsor: ProfoundBio US Co.


This is a global, open-label, multicenter Phase 1/2 study to evaluate the safety, tolerability, PK, and antitumor activity of PRO1107 in patients with advanced solid tumors. This study consists of 2 parts, Part A: dose escalation and dose level expansion, and Part B: tumor specific expansion.


This is a Phase 1/2 study of PRO1107, a PTK7 targeted antibody-drug conjugate, to evaluate the safety, tolerability, PK, and antitumor activity of PRO1107 in patients with advanced solid tumors, including ovarian cancer, endometrial cancer, triple negative breast cancer, non-small cell lung cancer, gastroesophageal cancer, and urothelial cancer. This study consists of 2 parts, Part A: Dose Escalation and Part B: Dose Expansion.

Part A may evaluate up to 7 dose levels of PRO1107 on Day 1 of a 21 day cycle by IV infusion.

Part B will be initiated at a dose level based on a comprehensive analysis of safety, tolerability, clinical PK, PD and activity data from Part A in up to 4 different cohorts of up to 40 patients per cohort.

Patients will continue to receive study treatment until the first instance of disease progression, unacceptable toxicity, investigator decision, consent withdrawal, study termination by the Sponsor, pregnancy, or death.
