A Study to Evaluate PEEL-224 in Patients With Advanced Solid Tumors

Phase 1
Recruiting
Conditions
Advanced Solid Tumor
Interventions
Registration Number
NCT05329103
Lead Sponsor
Peel Therapeutics Inc
Brief Summary

This is a first-in-human, dose escalation, repeat-dose, multi-center, open-label study evaluating safety, tolerability, PK, and preliminary antitumor activity of PEEL-224 in patients with advanced solid tumors.

Detailed Description

This is a first-in-human, dose escalation, repeat-dose, multi-center, open-label study evaluating safety, tolerability, PK, and preliminary antitumor activity of a novel topoisomerase I inhibitor (PEEL-224) in patients with advanced solid tumors. Dose escalation will be guided by the modified toxicity probability interval-2 (mTPI-2) design with a target toxicity rate of 25% and an acceptable DLT interval of 20% to 30%. Cohorts of 2 or more patients will be sequentially enrolled at progressively higher dose levels of PEEL-224. For each dose level, all patients must complete Cycle 1 before the decision to dose escalate the next cohort of patients is made.

GroupInterventionDescription
PEEL-224 Dose EscalationPEEL-224PEEL-224 is administered intravenously (IV) on Days 1, 8, and 15 of a 28-day cycle. The study will begin at a low starting dose and will increase between cohorts according to mTPI-2 until a recommended phase 2 dose is determined. Approximately 10 dose levels are anticipated to be studied.
PEEL-224 Dose ConfirmationPEEL-224An additional arm of patients will be enrolled after dose escalation is completed to confirm the recommended phase 2 dose.
