(the “Company” or “HCW Biologics”) (NASDAQ: HCWB), a clinical-stage biopharmaceutical company focused on discovering and developing novel immunotherapies to lengthen healthspan by disrupting the link between inflammation and age-related diseases, today reported financial results and recent business highlights for its second quarter ended June 30, 2024. Dr. Hing C. Wong, Founder and CEO of HCW Biologics, stated, “We reached a critical milestone recently that has profound implications for the future of our Company -- we successfully reached a settlement agreement for an arbitration that created an overhang that hampered our progress for nearly two years. We wasted no time in launching our multi-faceted financing plan, including a significant equity offering and a reinvigorated out-licensing program. We have a bright future ahead, as we have emerged with the TOBI™ platform and a strong portfolio of TOBI™-based molecules, as well as several development-stage ideas that we consider “next generation” immunotherapeutics which leverage what we learned from the human data readouts from the initial phases of our clinical trials. We remain committed to developing immunotherapeutic drugs that target the reduction of senescent cells and the proinflammatory factors they secrete. Our focus continues to be on senescence-associated disorders, most typical in age-related diseases, including cancer. We are also excited to bring HCW9302 to the clinic in the very near future to evaluate this drug in the treatment of autoimmune diseases by expanding regulatory T cells.” Business Highlights On July 13, 2024, the Company entered into a confidential Settlement Agreement and Release (“Settlement Agreement”) to resolve arbitration brought against the Company and Dr. Hing C. Wong, the Company’s Founder and Chief Executive Officer. The Settlement Agreement includes mutual general releases by and among all the parties. There were no monetary payments or damages paid by any party under the Settlement Agreement. See “Financial Guidance.”Going forward, the Company retains ownership and control of the TOBI™ platform and TOBI™-based molecules, with no restrictions under the Settlement Agreement on its ability to use the TOBI™ platform for protein-fusion molecules for non-oncology indications. The Company may pursue the clinical development of treatments for cancer indications based on HCW9302, HCW9206 and HCW9201. Further, HCW Biologics retains ownership of the Wugen license and shares of Wugen common stock transferred to the Company as the upfront licensing fee from Wugen for granting the Wugen license.A new financing plan was launched including an equity offering, which the Company intends to close before the end of 2024. Financing plans also include out-licensing non-core assets, and there are several discussions underway with potential licensing partners. Second Quarter 2024 Financial Results Revenues: Revenues for the quarter ended June 30, 2023 and 2024 were $622,807 and $618,854, respectively. Revenues for the six months ended June 30, 2023 and 2024 were $664,690 and $1.7 million, respectively. Revenues in both periods were derived exclusively from the sale of licensed molecules to the Company’s licensee, Wugen. The licensed molecules are one of the inputs for manufacturing Wugen’s products.Research and development (R&D) expenses: R&D expenses for the quarter ended June 30, 2023 and 2024 were $1.6 million and $2.0 million, respectively, an increase of $412,520, or 26%. R&D expenses for the six months ended June 30, 2023 and 2024 were $3.9 million and $4.2 million, respectively, an increase of $279,991, or 7%. Manufacturing costs increased in three- and six-month periods ended June 30, 2024 because the Company was replenishing its supply of a high-expressing cell line of HCW9101. Preclinical expenses declined in the three- and six-month periods ended June 30, 2024 due to a change in the types of activities being performed in connection with IND-enabling activities to prepare an IND application to obtain permission from the FDA to evaluate HCW9302 in an autoimmune indication. In the three- and six-month periods ended June 30, 2023, preclinical costs were incurred for setup costs for toxicology studies and other IND-enabling studies. In the three- and six-month periods ended June 30, 2024, costs were incurred for supplemental research studies. Clinical trial expenses were incurred in the three- and six-month period ended June 30, 2023 related to two clinical studies to evaluate HCW9218 in chemo-refractory / chemo-resistant solid tumors. Clinical trial expenses declined in the three- and six-month periods ended June 30, 2024 because these trials were fully enrolled in the first quarter of 2024.General and administrative (G&A) expenses: G&A expenses for the quarter ended June 30, 2023 and 2024 were $1.6 million and $1.6 million, respectively, an increase of $6,332, or 0%. The increase was primarily attributable to an increase in fees for auditing and tax advisory services, offset by a reduction in salaries and benefits arising from the Company’s cost-cutting measures. G&A expenses for the six months ended June 30, 2023 and 2024 were $3.6 million and $3.2 million, a decrease of $436,454, or 12%. The decrease was a result of cost-cutting measures and a decrease in legal fees incurred in procuring patents and insurance-related costs, partially offset by an increase in financing costs.Legal Expenses: Legal expenses for the quarter ended June 30, 2023 and 2024 were $1.4 million and $10.4 million, respectively, an increase of $9.0 million, or 629%. Legal expenses for the six months ended June 30, 2023 and 2024 were $2.5 million and $14.8 million, an increase of $12.3 million, or 484%.
