Etirinotecan Pegol Passes Interim Efficacy Analysis for BEACON Pivotal Phase 3 Clinical Study in Patients with Metastatic Breast Cancer

Nektar Therapeutics

announced today that the Independent Data Monitoring Committee (DMC) created to provide safety oversight for the Company's pivotal clinical study for etirinotecan pegol (NKTR-102) has recommended continuation of the BEACON phase 3 trial, based upon the completion of a planned interim efficacy analysis in accordance with the DMC charter.  The BEACON trial is evaluating NKTR-102 versus an agent of physician's choice for the treatment of locally recurrent or metastatic breast cancer, with a primary efficacy endpoint of overall survival. NKTR-102 is the first long-acting topoisomerase I-inhibitor designed to concentrate in tumor tissue, provide sustained tumor suppression throughout the entire chemotherapy cycle, and to reduce the peak exposures that are associated with toxicities of other cytotoxics.
