About the trial

What the trial wants to find out

This is a single arm, open label trial to assess the safety and efficacy of tucatinib in combination with pembrolizumab and trastuzumab for the treatment of HER2+ breast cancer brain metastases (BCBM). A total of 33 patients with untreated or previously treated and progressing HER2+ BCBM not requiring urgent central nervous system (CNS)-directed therapy will be enrolled. The study will determine the recommended dose of tucatinib in this combination and assess the efficacy of this combination in controlling CNS disease in patients with HER2+ BCBM.

The group in the trial

  • Tucatinib + Pembrolizumab + TrastuzumabTreatment being tested

    Patients will receive a combination therapy of tucatinib with pembrolizumab and trastuzumab during the treatment period until progression, treatment intolerance, or patient withdrawal from study. Tucatinib and pembrolizumab are administered as experimental use while trastuzumab is administered per standard use. Patients are expected to be on treatment for at least 12 weeks.

    Treatment: Tucatinib, Pembrolizumab, and Trastuzumab
