Trial Summary

Do I need to stop my current medications to join the trial?

The trial requires a 'washout period' (time without taking certain medications) before starting the study. This includes stopping any anti-cancer therapy, including hormonal therapy, for at least 3 weeks, and other specific medications like chloroquine/hydroxychloroquine for more than 14 days. It's best to discuss your current medications with the trial team to see if they need to be stopped.

What data supports the effectiveness of the drug Dato-DXd for treating triple-negative breast cancer?

Research shows that the drug datopotamab deruxtecan (Dato-DXd) has shown encouraging response rates in patients with advanced triple-negative breast cancer, with 34% experiencing a complete or partial response. Additionally, eribulin, another component of the treatment, has been found to work well with other drugs to kill cancer cells in this type of breast cancer.12345

Is Dato-DXd safe for humans?

In early trials, Dato-DXd showed manageable toxicity, meaning side effects were present but could be controlled, in patients with advanced triple-negative breast cancer.12346

What makes the drug Dato-DXd unique for treating triple-negative breast cancer?

Dato-DXd is unique because it is an antibody-drug conjugate that targets TROP-2, a protein often found in triple-negative breast cancer, and delivers a topoisomerase I inhibitor directly to the cancer cells, potentially improving effectiveness and reducing side effects compared to traditional chemotherapy.23478

What is the purpose of this trial?

This trial is testing a new drug called Dato-DXd to see if it works better than current treatments for patients with a specific type of breast cancer that has come back or spread and cannot be treated with certain common therapies. The drug aims to target and kill cancer cells more effectively.

Eligibility Criteria

This trial is for adults with triple-negative breast cancer that's locally recurrent and inoperable or has spread (metastatic), who haven't had chemotherapy for this condition, and can't use PD-1/PD-L1 inhibitor therapy. Participants need at least one measurable tumor lesion, good physical status (ECOG PS 0 or 1), adequate organ function, a life expectancy of over 12 weeks, and must not be pregnant or breastfeeding.

Inclusion Criteria

My cancer is HER2 negative according to specific testing guidelines.
You are expected to live for at least 12 weeks.
I am using birth control as per my local guidelines.

Treatment Details

Interventions

  • Capecitabine
  • Carboplatin
  • Dato-DXd
  • Eribulin mesylate
Trial Overview The study compares Dato-DXd to standard chemotherapies like Paclitaxel and Nab-paclitaxel in patients with advanced triple-negative breast cancer. It's an open-label Phase III trial where participants are randomly assigned to either the test drug group or the control group receiving investigator's choice of chemotherapy.

Findings from Research

In a phase I trial, datopotamab deruxtecan showed promising response rates, with 34% of patients with advanced or metastatic triple-negative breast cancer experiencing a complete or partial response.
The treatment was found to have manageable toxicity, indicating it may be a safe option for patients who have not responded to multiple previous therapies.

The phase III TROPION-Breast02 trial is investigating the efficacy and safety of the antibody-drug conjugate datopotamab deruxtecan (Dato-DXd) in approximately 600 patients with locally recurrent inoperable or metastatic triple-negative breast cancer (TNBC) who have not received prior treatment.
Dato-DXd is designed to target TROP2 and deliver a topoisomerase I inhibitor directly to cancer cells, and the trial will compare its effectiveness against standard chemotherapy options, focusing on progression-free survival and overall survival as primary outcomes.
TROPION-Breast02: Datopotamab deruxtecan for locally recurrent inoperable or metastatic triple-negative breast cancer.Dent, RA., Cescon, DW., Bachelot, T., et al.[2023]
DZ-2384, a new microtubule-targeting agent, shows strong effectiveness against triple-negative breast cancer (TNBC) in preclinical models, outperforming traditional taxanes like paclitaxel in terms of reduced toxicity and a wider therapeutic window (14-32 compared to 2.0 for paclitaxel).
DZ-2384 not only effectively reduces brain metastatic lesions but also works synergistically with anti-CTLA-4 immunotherapy, suggesting it could enhance treatment outcomes when combined with immune checkpoint inhibitors.
DZ-2384 has a superior preclinical profile to taxanes for the treatment of triple-negative breast cancer and is synergistic with anti-CTLA-4 immunotherapy.Bernier, C., Soliman, A., Gravel, M., et al.[2019]
