CAMBRIDGE, United Kingdom and CAMBRIDGE, Mass., May 10, 2022 (GLOBE NEWSWIRE) -- F-star Therapeutics, Inc. (NASDAQ: FSTX) (“F-star” or the “Company”), a clinical-stage biopharmaceutical company dedicated to developing next-generation immunotherapies to transform the lives of patients with cancer, today announced first quarter 2022 financial results and provided a corporate update.

“This year is one of the most important years in F-star’s history, with data readouts expected across all four of our clinical programs, expansion of our partnering activities, and continued development of our organization,” said Eliot Forster, CEO of F-star Therapeutics, Inc. “During the quarter, we increased the number of clinical sites for FS118 and FS120 by expanding beyond the US into the EU. We have also further advanced our understanding of the differentiated mechanism of FS118 in modulating LAG-3 cell surface expression. F-star continues to execute and create value for shareholders by advancing our programs and enabling our partners to develop next-generation bispecific therapeutics by leveraging the power of our discovery platform.”

First Quarter 2022 and Recent Highlights:

• Patients dosed in FS120 and FS118 trials in Europe, adding to the ongoing clinical activities in the US.
• Appointment of James Sandy as Chief Development Officer: Mr. Sandy brings over 35 years of experience in the pharmaceutical and biotechnology industries. James brings valuable additional expertise to the team in accelerating cancer treatment programs through early and late-stage development that will greatly benefit our clinical development strategy.
• FS118 poster presented at the American Association for Cancer Research (AACR) 2022 Annual Meeting demonstrating a novel LAG-3 reduction and shedding mechanism: Data revealed that the tetravalent and unique structure of FS118 plays a critical role in evoking LAG-3 shedding and cell surface reduction by tumor-infiltrating lymphocytes (TILs), enabling FS118 to overcome compensatory upregulation of LAG-3 induced by PD-(L)1 blockade.
• Fourth licensing option exercised by Merck KGaA, Darmstadt, Germany: Under the terms of the agreement, Merck KGaA, Darmstadt, Germany will be responsible for all future development and commercialization costs of the bispecific program and will pay future success-based milestones and royalties on any net sales resulting from programs covered by the agreement.
• IP portfolio expansion with the issuance of U.S. patent further protecting FS118: United States Patent and Trademark Office (USPTO) has granted a patent protecting the composition of matter of FS118, F-star’s tetravalent bispecific antibody which blocks PD-L1 and LAG-3 receptors. U.S. Patent No. 11,214,620 is entitled “Binding Molecules Binding PD-L1 and LAG-3” and is expected to provide F-star with exclusivity for FS118 out to at least August 2038.
• Participation in investor conferences: The management team participated in four investor conferences in the first quarter.

Anticipated 2022 Program Milestones:

• A clinical efficacy readout of FS118 in PD-1 acquired resistance head and neck cancer patients who have failed checkpoint therapies.
• Clinical update on FS222 Phase 1 trial.
• Clinical update on the Phase 1 trial of FS120 and initiation of the combination with Merck’s pembrolizumab.
• Clinical update of the dose-escalation study of SB 11285.

First-Quarter 2022 Financial Update

Cash Position
Cash and cash equivalents were $68.8 million as of March 31, 2022, compared to $78.5 million at December 31, 2021.

Research & Development Expense
Research & Development (R&D) expenses were $8.0 million for the quarter ended March 31, 2022, compared to $7.1 million for the corresponding quarter in 2021. This increase of $0.9 million in R&D expense is primarily due to increased CRO costs as more patients are enrolled in clinical studies, increased R&D staff related costs primarily to support clinical operations, offset by a reduction in manufacturing costs.

General & Administrative Expense
General & Administrative (G&A) expenses were $5.7 million for the quarter ended March 31, 2022, compared to $6.4 million for the first quarter 2021. The $0.7 million decrease is primarily due to a decrease in stock compensation expense, and legal and professional costs due to costs incurred in the comparative period for work in relation to the share exchange transaction with Spring Bank Pharmaceuticals. These decreases were offset by increases in facilities-related costs and information technology costs.

Net Loss Attributable to Common Shareholders
Net loss attributable to common shareholders was $12.1 million or $0.57 per share, for the quarter ended March 31, 2022, as compared to a net loss of $9.7 million or $1.07 per share for the quarter ended March 31, 2021.

Such forward-looking statements are based on our expectations and involve risks and uncertainties; consequently, actual results may differ materially from those expressed or implied in the statements due to a number of factors, including, but not limited to, the cash balances of F-star, the ability of F-star to remain listed on the Nasdaq Capital Market, F-star’s status as a clinical stage immuno-oncology company and its need for substantial additional funding in order to complete the development and commercialization of its product candidates, that F-star may experience delays in completing, or ultimately be unable to complete, the development and commercialization of its product candidates, that F-star’s clinical trials may fail to adequately demonstrate the safety and efficacy of its product candidates, that preclinical drug development is uncertain, and some of F-star’s product candidates may never advance to clinical trials, that results of preclinical studies and early stage clinical trials may not be predictive of the results of later stage clinical trials, that F-star relies on patents and other intellectual property rights to protect its product candidates, and the enforcement, defense and maintenance of such rights may be challenging and costly, and that F-star faces significant competition in its drug discovery and development efforts.

New factors emerge from time to time and it is not possible for us to predict all such factors, nor can we assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
