Hamilton, BERMUDA

NEW YORK, April 28, 2020 (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 cancer immunotherapies for a broad range of cancer indications, today announced that it has released its annual letter to shareholders.

In the shareholder letter Angelos Stergiou, MD, ScD h.c., SELLAS’ President & Chief Executive Officer, addresses the Company's product development, anticipated clinical milestones, and operational plans for 2020. Excerpted here are two key passages: “As I write this letter, we are in unprecedented times and all of us at SELLAS wish you and your families to remain safe and healthy. Although we are now all living through this COVID-19 pandemic, I hope to convey a theme of growth and transformation at SELLAS as we are further advancing our clinical programs and remain diligent in our business development and licensing efforts. We greatly appreciate your dedication and support of our company over the years and we are confident that 2020 will demonstrate that your loyalty was well-placed.”

“SELLAS remains clear in its mission and vision to develop and deliver complex and innovative treatments for patients battling cancer. Against the backdrop of the current pandemic, we are doing our best to manage those elements of our business that we believe we can control – progressing our assets, generating clinical and immunobiological data, executing on clinical development and progressing with business development opportunities. As of this writing, the three ongoing clinical trials for our lead clinical candidate, galinpepimut-S (GPS), have not been materially impacted. And our business development efforts seeking a licensee for our Phase 3 ready nelipepimut-S (NPS) are also continuing. As such, we plan to continue to report data from our programs as it becomes available throughout the remainder of 2020 and into 2021.”
