NEW YORK, Aug. 10, 2023 (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 provided a business update and reported its financial results for the quarter ended June 30, 2023.
“We are pleased with the solid progress across our clinical programs in the first half of the year. We expect to complete enrollment in our Phase 3 REGAL study of galinpepimut-S (GPS) in the second half of this year. In addition to our REGAL study, following a strong safety and efficacy profile for SLS009, our CDK9 inhibitor, as a monotherapy in acute myeloid leukemia (AML) in our Phase 1 study, we are particularly excited about the commencement of the Phase 2a study of SLS009 in combination with azacitidine and venetoclax in relapsed and refractory AML, for which we expect topline data in the fourth quarter of 2023,” said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. “The focus of our clinical programs is to potentially deliver treatments to impact the lives of patients with AML, from tackling active disease to prolonging patients’ lives in the maintenance setting, and we look forward to our upcoming milestones across the AML treatment landscape.”
Pipeline Update:
Galinpepimut-S (GPS): Wilms Tumor-1 (WT1) targeting immunotherapeutic
Phase 3 REGAL study in AML:
The interim analysis of the ongoing REGAL global Phase 3 registrational clinical trial of GPS in patients with AML who have achieved complete remission following second-line salvage therapy (CR2 patients) is expected in late 2023 or early 2024.
In April, the Independent Data Monitoring Committee (IDMC) recommended that REGAL continue as planned, following a routine, prespecified risk-benefit assessment of unblinded data from the study. The next routine IDMC meeting is scheduled for the third quarter of 2023.
A trial in progress poster titled “A randomized, open-label study of the efficacy and safety of galinpepimut-S (GPS) maintenance monotherapy compared to investigator's choice of best available therapy (BAT) in patients with acute myeloid leukemia (AML) who have achieved complete remission (CR) after second-line salvage therapy” was presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in June.
Phase 1/2 Study in combination with pembrolizumab (Keytruda®) in ovarian cancer:
SELLAS plans to present final data at the International Gynecologic Cancer Society Annual Meeting in November 2023.The topline data showed clinical benefit of GPS and anti-PD-1 pembrolizumab combination therapy in WT1 positive relapsed or refractory platinum resistant advanced metastatic ovarian cancer patients.
Phase 1 Study in combination with nivolumab (Opdivo®) in MPM:
SELLAS reported topline data from the investigator sponsored open-label Phase 1 trial for GPS combination therapy with checkpoint inhibitor nivolumab (Opdivo®) for treatment of malignant pleural mesothelioma (MPM) in patients who were either refractory to or relapsed after at least one line of the standard of care therapy. Safety and efficacy endpoints were met with clinical activity and increased survival observed. Additional immune response data is expected in the fourth quarter of 2023.
SLS009: highly selective CDK9 inhibitor
Phase 1 clinical trial in relapsed/refractory (r/r) hematological malignancies:
The safety evaluation stage of the Phase 1 dose escalation clinical trial of SLS009 was completed for the highest dose cohort of AML patients who relapsed after or were refractory to available antileukemic therapies. No further dose escalations are planned in the AML group, while dose escalation continues in the lymphoma group with the addition of 75 mg and 100 mg once-a-week dose cohorts. The 100 mg cohort is planned to likely be the highest dose level for the lymphoma group. Observed clinical activity in the lymphoma group will be announced after the last dose level is complete and is expected during the third quarter of 2023.
SELLAS reported positive topline data in the second quarter of 2023 for the AML cohort as a monotherapy which supported advancement to a Phase 2a trial in AML with SLS009 in combination with azacitidine and venetoclax (aza/ven).
Phase 2a clinical trial in AML:
A Phase 2a trial was initiated studying SLS009 combination treatment with aza/ven in r/r AML patients who did not respond or stopped responding to venetoclax-based therapies. The Phase 2a clinical trial is an open label, single arm, multi-center study that is designed to evaluate safety, tolerability, and efficacy at two dose levels of SLS009. The first patients were dosed in June and topline data are expected in the fourth quarter of 2023.
Hosted a virtual expert panel discussion:
SELLAS hosted a virtual expert panel discussion on SLS009 in AML in May featuring hematology-oncology specialists Tapan Kadia, MD (The University of Texas MD Anderson Cancer Center), Joshua Zeidner, MD (University of North Carolina Lineberger Comprehensive Cancer Center), and Omer Jamy, MD (O’Neal Comprehensive Cancer Center at the University of Alabama) who discussed the treatment landscape for AML and the potential for SLS009 to address unmet medical needs for patients with relapsed and/or refractory AML. A replay of the event is available on SELLAS’ website.
Corporate Updates:
SELLAS expects to receive milestone payments totaling $13.0 million from 3D Medicines by the end of the third quarter of 2023.
Financial Results for the Second Quarter 2023:
R&D Expenses: Research and development expenses for the second quarter of 2023 were $5.9 million, compared to $5.5 million for the same period in 2022. Research and development expenses for the first half of 2023 were $13.1 million, compared to $10.1 million for the same period in 2022.The increase was primarily due to an increase in clinical trial expenses related to the ongoing Phase 3 REGAL clinical trial of GPS in AML patients and the ongoing Phase 2a and Phase 1 clinical trials of SLS009 in hematological malignancies, increased clinical and regulatory consulting, and personnel-related expenses due to increased headcount.
G&A Expenses: General and administrative expenses for the second quarter of 2023 were $3.1 million, as compared to $3.1 million for the same period in 2022. General and administrative expenses for the first half of 2023 were $7.2 million, as compared to $6.1 million for the same period in 2022. The increase was primarily due to personnel-related expenses due to increased headcount.
Acquired In-Process Research and Development: There was no acquired in-process research and development for the first half of 2023 and second quarter of 2022. Acquired in-process research and development was $10.0 million for the first half of 2022, resulting from the in-licensing of SLS009.
Net Loss: Net loss was $8.8 million for the second quarter of 2023, or a basic and diluted loss per share of $0.31, compared to a net loss of $8.4 million for the same period in 2022, or a basic and diluted loss per share of $0.41.
