NEW YORK, Aug. 11, 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 provided a business update and reported its financial results for the quarter ended June 30, 2022.
“During the second quarter of 2022, SELLAS continued to progress our pipeline of treatment options to potentially improve and prolong the lives of patients battling cancer, with our lead asset, GPS, achieving several important milestones,” said Angelos Stergiou, M.D., Sc.D. h.c., President and Chief Executive Officer of SELLAS. “We reported clinical benefits seen in preliminary data from our Phase 1/2 clinical trial of GPS in combination with the checkpoint inhibitor KEYTRUDA® in patients battling WT1+ advanced ovarian cancer as well as encouraging updated clinical data from a Phase 1 investigator-sponsored clinical trial of GPS in combination with another checkpoint inhibitor, OPDIVO®, in patients with malignant pleural mesothelioma (MPM). In our Phase 3 REGAL study, we continued enrolling patients and activating additional sites across the United States, Europe, and Asia.”
“Additionally, we were pleased to report encouraging preliminary results for our GFH009 program, a novel and highly selective, potentially first and best in class CDK9 inhibitor. Clinical data from the ongoing Phase 1 dose-escalating clinical trial of GFH009 in the United States and China in advanced relapsed and refractory lymphoma and acute myeloid leukemia (AML) shows no dose-limiting toxicities at all dose levels studied to date, while also demonstrating early indications of biological efficacy in assessable patients at multiple dose levels. We are excited by these preliminary results as well as the data from preclinical in vitro studies showing significant inhibition of cancer cell growth in four cell lines announced earlier this week, and we look forward to continuing to study GFH009 to further explore its anticancer effects,” concluded Dr. Stergiou.
Galinpepimut-S (GPS): Wilms Tumor-1 (WT1) targeting peptide immunotherapeutic
Phase 1/2 Study in Combination with KEYTRUDA (pembrolizumab): In May 2022, SELLAS announced top-line clinical data showing clinical benefit from its Phase 1/2 trial of GPS in combination with Merck’s anti-PD-1 therapy, KEYTRUDA, in patients diagnosed with WT1+ relapsed or refractory platinum resistant advanced metastatic ovarian cancer.
Phase 1 Study in Combination with OPDIVO (nivolumab): In June 2022, SELLAS announced encouraging updated clinical data from a Phase 1 investigator-sponsored clinical trial of GPS in combination with the checkpoint inhibitor OPDIVO in patients with MPM who were either refractory to or relapsed after at least one line of the standard of care therapy.
Phase 3 REGAL Study: During the second quarter of 2022, SELLAS continued enrolling patients and activated additional sites in Poland, Greece and Hungary for its registrational global Phase 3 REGAL clinical trial in patients with AML. Enrollment for the study is scheduled to be completed in early in 2023, with an interim analysis planned to occur by the end of the first half of 2023. This timeline is based on current assumptions related to COVID-19 and its impact on the operations of clinical sites, as well as the duration of the pandemic. Because the interim analysis is event driven, it may become available at a different time than currently expected. The Company plans to activate additional sites in the United States and several countries in Europe and Asia throughout the remainder of 2022, including Serbia, Spain, Italy, Poland, Turkey and Taiwan.
GFH009: small molecule, highly selective CDK9 inhibitor
Preclinical In Vitro Studies in Solid Cancer and AML Cell Lines: In early August, the Company announced results from its preclinical in vitro studies in solid cancer and AML cell lines. The data shows that GFH009 demonstrated significant anti-tumor effects in all four selected cell lines with cancer cell growth inhibited by 90 to 100 percent in three out of the four cell lines and by more than 50 percent in the fourth cell line.
Clinical Update on Phase 1 Trial: As of August 1, 2022, enrollment at all originally planned dose levels, administered twice a week, in the AML group (30 mg) and at the 22.5 mg dose level for the lymphoma group was completed. Among the 30 patients evaluable for safety and efficacy, no dose limiting toxicities have been observed. Four lymphoma patients (three at 4.5 mg and one at 9 mg) achieved stable disease (SD). One patient with peripheral T cell lymphoma treated at the 9 mg dose had 62% decrease in sum of the product of the perpendicular diameters for multiple lesions (SPD) based on computed tomography (CT). Two AML patients, one treated at the 9 mg dose level and one treated at the 15 mg dose level, had decreases of bone marrow blasts equal to or greater than 50%.
Phase 1 Clinical Trial Protocol Amendment: The Company announced in July that a second, once-a-week dose cohort has been added in its ongoing Phase 1 clinical trial in both the United States and China to study once-a-week administration starting at the higher dose level of 30 mg which will provide additional data for the safety and efficacy profile for GFH009.
Underwritten Public Offering: On April 5, 2022, the Company closed an underwritten public offering providing gross proceeds of $25.0 million, before deducting underwriting discounts and commissions and offering expenses.
Milestone Payment: The Company received a $1.0 million milestone payment in May 2022 for the approval by China’s National Medical Products Administration (NMPA) of an IND application to initiate the first clinical trial in China for GPS.
Financial Results for the Second Quarter 2022:
Licensing revenue: There was no licensing revenue for the second quarter of 2022 and $1.0 million for the first half of 2022, which related to China’s NMPA approval of an IND application by 3D Medicines. This compares to $1.9 million for the second quarter of 2021 and $7.6 million for the first half of 2021.
R&D Expenses: Research and development expenses for the second quarter of 2022 were $5.5 million, compared to $3.5 million for the same period in 2021. Research and development expenses were $10.1 million for the first half of 2022, compared to $7.7 million for the same period in 2021. The increase was primarily due to an increase in clinical trial expenses related to the Company’s ongoing Phase 3 REGAL clinical trial of GPS in AML patients, a ramp up of the manufacture of clinical trial materials and registration batches of GPS, and personnel related expenses due to increased headcount.
Acquired In-Process Research and Development: There was no acquired in-process research and development for the 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 GFH009. There was no acquired in-process research and development during the same periods in 2021.
G&A Expenses: General and administrative expenses for the second quarter of 2022 were $3.1 million, as compared to $2.8 million for the same period in 2021. The increase was primarily due to personnel related expenses due to increased headcount. General and administrative expenses were $6.1 million for the first half of 2022, compared to $6.4 million for the same period in 2021. The decrease was primarily due to a decrease in amortization expense associated with the capitalized contract acquisition costs of the 3D Medicines license agreement and a decrease in professional service fees, partially offset by an increase in personnel related expenses due to increased headcount.
Net Loss: Net loss was $8.4 million for the second quarter of 2022, or a basic and diluted loss per share of $0.41, compared to a net loss of $4.6 million for the same period in 2021, or a basic and diluted loss per share of $0.30. Net loss was $25.2 million for the first half of 2022, or a basic and diluted loss per share of $1.39, compared to a net loss of $7.0 million for the same period in 2021, or a basic and diluted loss per share of $0.47.
Cash Position: As of June 30, 2022, cash and cash equivalents totaled approximately $27.0 million.
