MIRAMAR, Fla., March 28, 2023 (GLOBE NEWSWIRE) -- HCW Biologics Inc. (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 chronic, low-grade inflammation and age-related diseases, today reported financial results and recent business highlights for its fourth quarter ended December 31, 2022.

Hing C. Wong, Ph.D., Founder and CEO of HCW Biologics, stated, “We had a productive year in 2022, and our cancer program met or exceeded key milestones. In the fall, a preliminary first-in-human clinical data readout was presented at the SITC annual conference by Dr. Melissa Geller, the principal investigator for the University of Minnesota (“UMN”) sponsored Phase 1 clinical trial to evaluate HCW9218 in solid tumors. We are encouraged by data gathered in this study and believe that it shows the potential of HCW9218 in the treatment of solid tumors, especially ovarian cancer.  Our data indicates that HCW9218 is functioning as it was intended – activating the immune system and capturing TGF-β 1, 2 and 3 with no evidence of mucosal bleeding.”

Dr. Wong continued, “UMN has been a terrific sponsor and partner for the Phase 1 solid tumor clinical study. With Dr. Geller’s expertise and focus, along with the support of the co-principal investigator, Dr. Jeff Miller, the Phase 1 portion of this trial is on track to be completed within a year of its initiation, which is fortunate in the times of prolonged COVID-related delays. Because of this, we are poised to complete the Phase 1 study in 2023 and, if our studies are successful, potentially advance into Phase 2 clinical trials in 2023.”

In the fourth quarter of 2022, the Company also initiated a Company-sponsored Phase 1b/2 clinical trial to evaluate HCW9218 in advanced pancreatic cancer.   Dr. Wong stated, “With respect to HCW9218, we believe cancer is our gateway indication to other age-related diseases. As and to the extent we advance the clinical development to evaluate HCW9218 in cancer indications, we intend to focus on two of the most difficult-to-treat cancers that have no therapeutic remedy today: ovarian cancer and pancreatic cancer.” He added, “If we can establish safety and dosage of HCW9218 in cancer indications, we plan to expand to other age-related diseases promoted by inflammaging.”

One of the pillars of the Company’s strategy is its commitment to documenting its work in high-impact scientific journals. Two scientific papers were submitted in 2022, one has been published, and the other has been accepted for publication. Dr. Wong stated, “We devote significant resources to publishing scientific papers, because we believe in the value of sharing our discoveries and inventions with the broader scientific community.”

Dr. Wong continued, “Our most recent paper published in Frontiers in Immunology illustrates the potential for HCW9302 as a therapeutic agent to expand and activate T_reg cells indicating it might be effective in treating inflammatory and autoimmune diseases. HCW9302 is a unique fusion protein with two IL-2 domains linked by an extracellular tissue factor domain that has been shown in preclinical research to exhibit a more favorable pharmacokinetic profile than recombinant IL-2, with longer half-life, greater affinity to IL-2 receptor α and no toxicity.   The results of our research included in this publication show the potential of HCW9302 in the treatment of age-related inflammatory diseases, such as atherosclerosis.”             

Fourth Quarter and Other Recent Business Highlights:

• On November 11, 2022, there was a preliminary human data readout at the 37^th Annual Meeting of the Society for Immunotherapy of Cancer from an ongoing Phase 1 clinical trial to evaluate HCW9218 in patients with chemo-refractory/chemo-resistant solid tumors, sponsored by the Masonic Cancer Center, University of Minnesota. The poster was presented by Melissa A. Geller, M.D., M.S., Principal Investigator, who is a Professor and Division Director of Gynecologic Oncology in the Department of Obstetrics, Gynecology and Women’s Health at the University of Minnesota.
• On December 3, 2022, under a Cooperative Research and Development Agreement (“CRADA”), the National Cancer Institute and HCW Biologics agreed to collaborate to perform a Phase 1b/2 clinical study to evaluate the safety and tolerability of HCW Biologics’ lead product candidate, HCW9218, in patients with advanced/metastatic pancreatic cancer. The CRADA is entitled, “A Phase 1b/2 Study of HCW9218, a Bifunctional TGF-β Antagonist/IL-15 Protein Complex, for Advanced Pancreatic Cancer.”
• HCW Biologics initiated a Company-sponsored Phase 1b/2 clinical study to evaluate HCW9218 in patients with advanced pancreatic cancer. With four clinical sites up and running, if patient enrollment continues at the current pace, the Company expects to complete the Phase 1b portion of this study in 2023.
• In January 2023, a pivotal scientific paper authored by members of the Company’s scientific research team was published in the high-impact, peer-reviewed journal, Frontiers in Immunology, entitled, “A Novel Interleukin-2-Based Fusion Molecule, HCW9302, Differentially Promotes Regulatory T Cell Expansion to Treat Atherosclerosis in Mice.”
• The Company has been invited to present a poster at the American Association of Cancer Research to be held from April 14-19, 2023. Dr. Varghese George, one of the Company's scientists, will be presenting a poster entitled, "Bifunctional Immunotherapeutic HCW9218 Facilitates Recruitment of Immune Cells from Tumor Draining Lymph Nodes to Promote Antitumor Activity and Enhance Checkpoint Blockade Efficacy in Solid Tumors." This research is intended to support the understanding of the mechanism of action for HCW9218 for solid tumors.

Financial Guidance

HCW Biologics believes its cash and cash equivalents and investments will be sufficient to fund its operations through at least the next 12 months. This cash runway guidance is based on the Company’s current operational plans and buildout of its new headquarters building, and it excludes any additional capital infusion resulting from bank loans, joint ventures, out-licenses, or other business development transactions. Relocation to the new headquarters is anticipated during 2024, although the Company may choose to delay the completion date to extend its cash runway. In the year ended December 31, 2022, the Company incurred significant legal expenses on its own behalf and on behalf of Dr. Wong, as required by the indemnification agreement between the Company and Dr. Wong. In the year ahead, the Company expect to continue to incur legal expenses on its own behalf in connection with the legal proceedings brought against it by Altor/NantCell. However, now that the arbitration against Dr. Wong was initiated by Altor/NantCell, Dr. Wong’s legal expenses will be covered by the provisions of his advancement agreement with Altor/NantCell in connection with the arbitration.
