SELLAS Announces Confirmatory Top-Line Data Showing Survival and Clinical Benefits Based on the Final Analysis of the Phase 1/2 Clinical Trial of Galinpepimut-S in Combination with Keytruda® (pembrolizumab) in Patients with WT1+ Platinum-Resistant Advanc
NEW YORK, Nov. 10, 2022 (GLOBE NEWSWIRE) -- SELLAS Life Sciences Group, Inc. (NASDAQ: SLS) (“SELLAS” or the “Company”), a late-stage clinical biopharmaceutical company focused on the development of novel therapies for a broad range of cancer indications, today announced confirmatory top-line clinical data from the final analysis of results from its Phase 1/2 clinical trial of galinpepimut-S (GPS), the Company’s Wilms Tumor-1 (WT1)-targeting peptide immunotherapeutic, in combination with Merck’s anti-PD-1 therapy, pembrolizumab (KEYTRUDA®), in patients diagnosed with WT1(+) relapsed or refractory platinum-resistant advanced metastatic ovarian cancer.
- Of the 17 patients, 16 received at least three doses of GPS and had follow-up cross-sectional imaging (CT/MRI) to determine tumor status.
- Importantly, survival and disease control benefits were observed in patients harboring tumors with any level of detectable PD-L1 expression, i.e., those with Combined Positive Score (CPS) of one or higher.
- The DCR is 63.6 percent in patients with a CPS of one or higher in this study.
- These forward-looking statements are based on current plans, objectives, estimates, expectations, and intentions, and inherently involve significant risks and uncertainties.
