Trial Outcomes & Findings for Testing Ado-Trastuzumab Emtansine as a Potential Targeted Treatment in Cancers With HER2 Genetic Changes (MATCH-Subprotocol Q) (NCT NCT04439110)

NCT ID: NCT04439110

Last Updated: 2025-11-21

Results Overview

ORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among eligible and treated patients. Objective response rate is defined consistent with Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. For each treatment arm, 90% two-sided binomial exact confidence interval will be calculated for ORR.

Participant Flow

Subprotocol Q was activated on August 12, 2015. A total of 58 patients were assigned to this arm after screening, all from screening cohort. Of the 58 patients, 38 patients were enrolled to arm Q between November 19, 2015 and March 20, 2017.

To be assigned to a specific MATCH subprotocol, patients needed to submit a tumor biopsy for molecular characterization and those with molecular variants addressed by treatments included in the trial entered corresponding MATCH subprotocol. For the subprotocol Q, patients had to have a tumor ERBB2 copy number of \>7.

PRIMARY outcome

Timeframe: Tumor assessments occurred at baseline, then every 3 cycles for the first 33 cycles and every 4 cycles thereafter until disease progression, up to 3 years post registration

Population: Patients who were eligible and received protocol treatment

ORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among eligible and treated patients. Objective response rate is defined consistent with Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients.

SECONDARY outcome

Timeframe: Assessed at baseline, then every 3 cycles for the first 33 cycles and every 4 cycles thereafter until disease progression, up to 3 years post registration

Population: Patients who were eligible and received protocol treatment

Progression free survival is defined as time from treatment start date to date of progression or death from any cause, whichever occurs first. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. 6 month PFS rate was estimated using the Kaplan-Meier method, which can provide a point estimate for any specific time point.
