Study Endpoints

Primary Endpoints

negative predictive value of the 89Zr-trastuzumab PET/CT
2 years

The primary objective is to show that pre-treatment 89Zr-trastuzumab PET/CT is able to select lesions not responding morphologically from treatment with T-DM1 (applying RECIST 1.0 criteria).

Secondary Endpoints

negative predictive value of the early FDG PET/CT
2 years
negative predictive value of the 89Zr-trastuzumab PET/CT
2 years
negative predictive value of the combined 89Zr-trastuzumab PET/CT and early PET/CT

Frequently asked questions about T-DM1

What is T-DM1 used for in HER-2 Positive Breast Cancer?

T-DM1 is an investigational small molecule being studied for the treatment of HER-2 positive breast cancer. It is currently in Phase 2 clinical development. The drug is being evaluated in patients with HER-2 positive metastatic breast cancer, specifically to identify those who are unlikely to benefit from treatment.

What does T-DM1 target?

T-DM1 targets HER-2, a protein that is overexpressed in certain types of breast cancer. The drug is designed to interact with HER-2 positive tumors, and its development includes biomarker-selected patient populations. This targeted approach is being studied in the context of HER-2 positive metastatic breast cancer.

Who makes T-DM1?

T-DM1 is being developed by Roche Holding AG, a company traded under the ticker symbol RHHBY. Roche is conducting clinical trials to evaluate the drug's efficacy in patients with HER-2 positive breast cancer. The development program is currently in Phase 2.

What phase is T-DM1 in?

T-DM1 is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The drug is being studied for its potential use in HER-2 positive breast cancer, with one completed Phase 2 trial involving 90 patients.

What clinical trials is T-DM1 in?

T-DM1 has been studied in one clinical trial, identified as NCT01565200. This Phase 2 trial, titled "HER2 Imaging Study to Identify HER2 Positive Metastatic Breast Cancer Patient Unlikely to Benefit From T-DM1," was completed and enrolled 90 participants. The study was conducted in Belgium and the Netherlands.

Is T-DM1 the same as ado-trastuzumab emtansine?

T-DM1 is also known as ado-trastuzumab emtansine. This alternative name is used in some contexts to refer to the same drug. The drug is being developed by Roche for the treatment of HER-2 positive breast cancer and is currently in Phase 2 clinical trials.
