Core Insights - CytoDyn Inc. is set to present clinical data at the San Antonio Breast Cancer Symposium (SABCS) demonstrating sustained remission in patients with metastatic or locally advanced triple-negative breast cancer (mTNBC) following immune checkpoint inhibitor therapy with or after leronlimab treatment [1][3] Company Overview - CytoDyn is a clinical-stage oncology company focused on advancing leronlimab, a first-in-class humanized monoclonal antibody targeting the CCR5 receptor, with potential applications in various cancers, including mTNBC and colorectal cancer [1][6] - The company aims to improve patients' quality of life through therapeutic innovation and is committed to integrity, responsibility, and service [6] Clinical Findings - mTNBC is associated with a poor prognosis, and the efficacy of immune checkpoint inhibitors is reduced in patients with low levels of PD-L1 [2] - Previous trials suggest that leronlimab treatment may increase PD-L1 levels, potentially improving survival when combined with immune checkpoint inhibitors [2] - The CEO of CytoDyn highlighted the promise of using leronlimab in combination with immune checkpoint inhibitors, noting that some patients have shown sustained long-term remission, including three individuals with no current evidence of disease [3] Presentation Details - The poster presentation will be led by Dr. Milana V.
