SELLAS Life Sciences Announces Positive Final Data in Triple Negative Breast Cancer Patients from Phase 2b Clinical Trial of Nelipepimut-S

SELLAS Life Sciences (Nasdaq:SLS) a clinical-stage biopharmaceutical company focused on the development of novel cancer immunotherapies for a broad range of cancer indications, today announced data from the prospective, randomized, single-blinded, controlled Phase 2b independent investigator-sponsored clinical trial of the combination of nelipepimut-S (NeuVax, NPS) +/- trastuzumab (Herceptin) targeting HER2 low-expressing breast cancer patient cohorts.

As quoted in the press release:

The data were presented in an oral presentation at the European Society for Medical Oncology (ESMO) 2018 Annual Meeting, being held in Munich, Germany.

“These data presented at ESMO today highlight the therapeutic potential of NPS for patients with early-stage triple negative breast cancer (TNBC), who currently face limited and ineffective treatment options in the adjuvant setting,” said Dr. Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. “The combination of NPS and trastuzumab demonstrated a clinically meaningful and statistically significant difference in the cohort of patients with TNBC with a 75.2% reduction in risk of relapse or death at 26 months.  Importantly, following review of the final data that were also assessed by the independent Data Safety Monitoring Board (DSMB) on October 15, 2018, there was an incremental further improvement of clinical benefit to patients now observed in comparison with the data from the interim analysis completed more than six months ago.”
