Summary

The purpose of this study is to evaluate the safety of TAK-164 and to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) and schedule.

Detailed description

The drug being tested in this study is a novel antibody-drug conjugate (ADC) called TAK-164. TAK-164 is being evaluated in participants with advanced GCC-positive GI cancer (Part A) or colorectal carcinoma (CRC) and gastric carcinoma (Part B and Part C) to determine safety, tolerability, and pharmacokinetics (PK) and MTD/RP2D of TAK-164, as well as the preliminary efficacy. The study will include approximately 100 evaluable participants. In Part A (Escalation), approximately 25 participants with GI carcinoma will be enrolled. Those include participants with various GI malignancies such as carcinomas of esophagus, stomach, colon, and pancreas. The starting dose for Arm 1 will be 0.004 mg/kg of TAK-164 administered intravenously on Day 1 Q3W and the maximal dose will not exceed 0.19 mg/kg Q3W. In Part B (Expansion), approximately 50 participants will be enrolled to receive TAK-164 infusion at determined RP2D in Part A. Participants will follow the Q3W schedule and will be followed until PD, unacceptable toxicity, or until they choose to withdraw consent. In Part C (Imaging substudy to be conducted in the Netherlands only), approximately 25 participants with GCC-expressing metastatic colorectal carcinoma (mCRC) will be enrolled to receive 89Zr-TAK-164 and unlabeled TAK-164 at determined RP2D in Part A. This multi-center trial will be conducted in the United States and the Netherlands. The overall time to participate in this study is up to 55 months. Participants will attend an end of study (EOS) visit 30 days after the last dose of TAK-164 or just prior to the start of subsequent antineoplastic therapy, whichever occurs first.
