NEW YORK, NY May 14, 2024 -- 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 reported financial results for the first quarter ended March 31, 2024, and provided a corporate update.
"SELLAS had a very productive and successful first quarter of 2024," said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. "We reported strong preliminary data from the Phase 2a study of SLS009 in r r AML showing high anti-leukemic activity in the selected optimal dose regimen of 30 mg BIW, including a 100% response rate in patients with ASXL1 mutation. Based on these results we are expanding the cohort to participants bearing the ASXL1 mutation. This mutation is prevalent in AML, as well as solid tumors including colon cancer, and is associated with poor prognosis. We strongly believe in SLS009's potential and hope to deliver its promise to this heavily pretreated, underserved patient population. The data thus far are indeed extremely encouraging both in terms of safety and efficacy."
Dr. Stergiou continued "We are also excited with the ongoing progress in the Phase 3 REGAL study of GPS. Based on its recent efficacy and safety assessment, the IDMC recommended the trial continue without modification. We look forward to the next IDMC meeting, scheduled for June, during which the Committee will review data from all enrolled 127 patients and the most recent information regarding the number of events required for triggering the interim analysis. Furthermore, with the recent financing, we were able to strengthen our balance sheet as we expect further significant catalysts throughout 2024."
Galinpepimut-S (GPS) Wilms Tumor-1 (WT1) targeting immunotherapeutic
Phase 3 REGAL study in AML Reached planned enrollment of patients in the United States, Europe, and Asia, following the predetermined statistical analysis plan. The IDMC conducted a prespecified risk-benefit assessment of unblinded data from the study and has recommended that the trial continue without modifications. The IDMC scheduled its next meeting in June 2024 to review the safety and efficacy data from all enrolled 127 patients.
SLS009 highly selective and specific CDK9 inhibitor
Announced Positive Phase 2 Data of SLS009 in r r AML The preliminary data showed 62% and 67% anti-leukemic activity at all dose levels and in the 30 mg BIW cohort, respectively, with a favorable safety profile. A 100% overall response rate (CR CRi MLFS) was achieved in patients with ASXL1 mutation in the 30 mg BIW cohort to date. Enrollment is ongoing at the 30 mg BIW cohort with ASXL1 mutation.
IP Protection Based on the SLS009 efficacy data in r r AML patients with ASXL1 mutation, SELLAS filed a provisional patent application. The ASLX1 mutations are associated with poor prognosis in all myeloid diseases, owing to the reduced response to the current treatment options.
Phase 1b 2 clinical trial in combination with BTK inhibitor, Brukinsa (zanubrutinib), in r r DLBCL GenFleet Therapeutics (Shanghai), Inc. entered into a clinical trial collaboration and supply agreement with BeiGene Switzerland GmbH and dosed the first patient in March 2024. The trial is an open-label single-arm multicenter Phase 1b 2 study to be conducted in two parts. In the Phase 1b portion, 6-18 patients will be enrolled and in the Phase 2 portion, approximately 45 patients will be enrolled. This study is being conducted in China and is funded by GenFleet which intends to focus on DLBCL as its lymphoma target with SLS009.
National Institute of Health PIVOT program in Pediatric Tumors The program in multiple pediatric cancer indications continues in collaboration with the National Cancer Institute (NCI). Initial safety and efficacy data are expected to be reported throughout 2H 2024.
Financial Results for the First Quarter 2024
R D Expenses Research and development expenses for the quarter ended March 31, 2024 were $5.1 million, compared to $7.2 million for the same period in 2023. The decrease was primarily due to the timing of a clinical drug supply purchase in the prior period and decreases in consultants, personnel related expenses due to changes in headcount, and licensing fees.
G A Expenses General and administrative expenses for the first quarter of 2024 were $4.5 million, as compared to $4.1 million for the same period in 2023. The slight increase was primarily attributed to the initial recognition of a one-time severance charge in the first quarter of 2024, partially offset by decreases in outside services and public company costs and other personnel related expenses.
Net Loss The net loss was $9.6 million for the first quarter of 2024, or a basic and diluted loss per share of $0.21, as compared to a net loss of $11.1 million for the first quarter of 2023, or a basic and diluted loss per share of $0.47.
Cash Position As of March 31, 2024, cash and cash equivalents totaled approximately $18.4 million.
