Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with histologically confirmed metastatic TNBC who have undergone one to three prior chemotherapy regimens.

Probably not a fit

Patients with symptomatic uncontrolled brain metastasis or those who have previously been treated with PI3K inhibitors for breast cancer may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase II, open-label, single-arm study aims to assess the efficacy and safety of tenalisib in patients diagnosed with metastatic triple negative breast cancer (TNBC). Eligible participants must have received between one and three prior therapies in a metastatic setting and have at least one measurable lesion. The study will monitor the treatment's effectiveness and safety profile in this specific patient population.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with metastatic TNBC who have limited treatment choices.

How similar studies have gone: While this approach is being evaluated in this specific context, similar studies targeting TNBC with novel therapies have shown promise, indicating potential for success.
