From the trial submitted June 9:
Brief Summary
This is a phase Ib/II Study of Leronlimab (PRO 140) combined with Carboplatin in Patients with CCR5+ Metastatic Triple Negative Breast Cancer (mTNBC).
Study population will consist of patients with CCR5-positive, locally advanced or metastatic triple-negative breast cancer (mTNBC) who are naïve to chemotherapy in metastatic setting but have been exposed to anthracyclines and taxane in neoadjuvant and adjuvant settings (first-line).
Detailed Description
Phase Ib
Phase Ib is a dose escalation phase with 3 dose levels (cohorts) of leronlimab (PRO 140) administered in combination with a fixed dose of carboplatin at AUC 5. This dose finding portion of study will follow a "3+3" designed to determine the maximum tolerated dose (MTD) of leronlimab (PRO 140) administered as subcutaneous injection in subjects with histologically confirmed mTNBC that express CCR5.
Phase II
Phase II is a single arm study with 30 patients in order to test the hypothesis that the combination of carboplatin AUC 5 intravenously and MTD of leronlimab (PRO 140) SC will increase PFS in patients with CCR5 + mTNBC.
This trial, per my weak understanding of the LL MOA, measured the LL sweet spot. Please correct me if I am wrong.
