Official title

A Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of Lutetium [177Lu] BL-ARC001 Injection in Patients With Locally Advanced or Metastatic Gastrointestinal Tumors and Other Solid Tumors

Overview

This study is an open-label, multicenter, non-randomized Phase I clinical trial to evaluate the safety, tolerability, pharmacokinetic profile, and preliminary efficacy of Lutetium \[177Lu\] BL-ARC001 in patients with locally advanced or metastatic solid tumors.

Detailed description

The study is divided into two phases: a dose escalation phase (Phase Ia) and a cohort expansion phase (Phase Ib).

  • Phase Ia: Maximum tolerated dose (MTD) [Time frame: Up to 42 days after the first dose]
  • Phase Ib: Recommended Phase II Dose (RP2D) [Time frame: Up to approximately 24 months]
Secondary outcome measures (12)
  • Treatment-Emergent Adverse Event (TEAE) [Time frame: Up to approximately 24 months]
  • Cmax [Time frame: Up to approximately 24 months]
  • Tmax [Time frame: Up to approximately 24 months]
  • T1/2 [Time frame: Up to approximately 24 months]
  • AUC0-t [Time frame: Up to approximately 24 months]
  • CL (Clearance) [Time frame: Up to approximately 24 months]
  • Ctrough [Time frame: Up to approximately 24 months]
  • ADA (anti-drug antibody) [Time frame: Up to approximately 24 months]
  • Distribution Characteristics [Time frame: Up to approximately 24 months]
  • Radiation Characteristics [Time frame: Up to approximately 24 months]
  • Phase Ib: Objective Response Rate (ORR) [Time frame: Up to approximately 24 months]
  • Phase Ib: Disease Control Rate (DCR) [Time frame: Up to approximately 24 months]
