Outcomes

Primary Outcome Measures

Number of Participants With Dose-limiting Toxicities (DLTs)

DLTs were evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5. DLT was defined as any of the following adverse events (AEs) that occurred and were considered by the investigator to be related to therapy with study drug: hematologic toxicities were, Grade 4 neutropenia (absolute neutrophil count [ANC] less than (<) 500 cells/cubic millimeter [mm^3]), thrombocytopenia (platelets <25,000/mm^3), febrile neutropenia (ANC <1000/mm^3) with fever (greater than [>] 38.3 degree Celsius or sustained temperature of greater than or equal to (>=) 38 degree Celsius, Grade 3 or greater thrombocytopenia with clinically meaningful bleeding at any time, Grade 3 or greater nausea and/or emesis that occurs despite the use of optimal anti-emetic prophylaxis and Grade 3 or greater diarrhea that occurs despite optimal supportive care measures and any other Grade 3 or greater nonhematologic toxicity except brief (<1 week) Grade 3 fatigue.

Percentage of Participants With Adverse Events (AEs)

Percentage of Participants With Grade 3 or Above AEs

AE Grades were evaluated as per NCI CTCAE, version 5. Graded from Grade 1: Mild asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated, Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL), Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL, Grade 4: Life-threatening consequences; urgent intervention indicated, Grade 5: Death related AE. Higher grade indicates more severe condition.

Percentage of Participants With Drug-related AEs

Percentage of Participants With Drug-related Grade 3 or Above AEs

AE Grades were evaluated as per NCI CTCAE, version 5. Graded from Grade 1: mild asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated, Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL, Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL, Grade 4: Life-threatening consequences; urgent intervention indicated, Grade 5: death related AE. Higher grade indicates more severe condition.

Percentage of Participants With Serious Adverse Events (SAEs)

Percentage of Participants With AEs Leading to Discontinuation

Recommended Phase 2 Dose (RP2D) of TAK-164

RP2D was the highest safe dose that could be applied to the expansion phase.

Secondary Outcome Measures

Cmax: Maximum Observed Plasma Concentration for TAK-164

Tmax: Time to Reach the Maximum Observed Plasma Concentration (Cmax) for TAK-164

AUClast: Area Under the Plasma Concentration-time Curve From Time 0 to Time of Last Quantifiable Concentration for TAK-164

Ctrough: Observed Concentration Measured at the End of a Dosing Interval for TAK-164

Overall Response Rate (ORR)

ORR was assessed by the investigator based on modified Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. ORR was defined as the percentage of participants who had complete response (CR) or partial response (PR). CR was defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to <10 millimeters (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum longest diameter.

Disease Control Rate (DCR)

DCR was defined as the percentage of participants with CR, PR or stable disease (SD). DCR was assessed based on modified RECIST version 1.1 criteria. CR was defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD was neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum longest diameter since the treatment started.

Duration of Response (DOR)

DOR was defined as the time from the date of first documentation of a response (CR or PR) to the date of first documented PD or death due to any cause, whichever occurred first based on modified RECIST version 1.1 criteria. CR was defined as the disappearance of all target and non-target lesions (non-lymph nodes). All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum longest diameters. PD was >=20% increase in sum of diameters of target lesions, reference-smallest sum recorded in study (sum at baseline if that was smallest). Sum of diameters must have absolute increase of >=5 mm. Appearance of >=1 new lesions also considered PD.

Progression-free Survival (PFS)

PFS was defined as the time from date of first study drug administration to the day of first documented PD or death due to any cause, whichever occurred first according to modified RECIST version 1.1 criteria. PD was >= 20% increase in sum of diameters of target lesions, reference-smallest sum recorded in study (sum at baseline if that was smallest). Sum of diameters must have absolute increase of >=5 mm. Appearance of >=1 new lesions also considered PD. PFS was censored at the last response assessment that is stable disease or better, prior to receipt of subsequent anticancer therapy, if applicable. Participants with no post-baseline assessments was censored at Day 1.

5. Study Description

Brief 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.
