Study Summary

A Phase 2, open-label, multicenter international study will be performed to evaluate the efficacy of MCLA-128-based combinations. Three combination treatments will be evaluated, two in Cohort 1 and one in Cohort 2. MCLA-128 (zenocutuzumab) is given in combinations in two metastatic breast cancer (MBC) populations, Human Epidermal Growth Factor Receptor (HER) 2-positive/amplified (Cohort 1) and Estrogen Receptor-positive/low HER2 expression (Cohort2). Two combinations treatments will be evaluated in Cohort 1, the doublet and triplet. Initially zenocutuzumab is given in combination with trastuzumab in the doublet. After the safety of the doublet has been assessed in 4-6 patients, MCLA-128 is given in combination with trastuzumab and vinorelbine in the triplet, in parallel to the efficacy expansion of the doublet. The doublet and triplet combinations are both evaluated in two steps with an initial safety run-in followed by a cohort efficacy expansion. In total up to 40 patients evaluable for efficacy are included in both the doublet and triplet. In Cohort 2 zenocutuzumab is administered in combination with the same previous endocrine therapy on which progressive disease is radiologically documented. A total of up to 40 patients evaluable for efficacy are included in the Cohort 2.
