Merrimack Identifies Heregulin as Patient Response Biomarker for MM-121 and Standard of Care Therapy Across Multiple Cancers

Results from three Phase 2 studies further showed that patients with heregulin-positive tumors experienced a statistically significant reduction in their risk of progression when they received a combination of MM-121 with their standard of care therapy as compared to patients who received the standard of care therapy alone. MM-121 is specifically designed to block heregulin binding to ErbB3.
