Collaboration explores the potential synergistic effects of Checkpoint's anti-PD-L1, cosibelimab, in combination with the autologous T cell therapy, Immuncell-LC
YONGIN, South Korea and WALTHAM, Mass., July 15, 2024 (GLOBE NEWSWIRE) -- GC Cell (KRX: 144510.KS) and Checkpoint Therapeutics ("Checkpoint") (NASDAQ:CKPT) have announced a collaboration to explore the combined therapeutic potential of cosibelimab, Checkpoint's anti-PD-L1 antibody with dual mechanism of action, with GC Cell's Immuncell-LC, an innovative autologous Cytokine Induced Killer ("CIK") T cell therapy composed of cytotoxic T lymphocytes and natural killer T cells.
This collaboration will initially focus on conducting in vitro combination studies to evaluate the synergistic effects of these two therapies on cancer cell destruction. Positive preliminary data from these studies could potentially pave the way for future in vivo research and clinical studies.
The anticipated synergy between cosibelimab's antibody-dependent cellular cytotoxicity ("ADCC") mechanism of action and Immuncell-LC's robust autologous CIK T cell response is supported by extensive research. This combination is expected to leverage immune system components more effectively in targeting and eliminating cancer cells.
James Park, CEO of GC Cell, highlighted the agreement's potential: "This collaboration is a pivotal step towards significant technological collaborations. The integration of cosibelimab's clinical efficacy and safety profile with our Immuncell-LC could set new therapeutic standards in immuno-oncology. We are optimistic that this partnership will lead to effective commercial licensing or joint development in the future."
James F. Oliviero, CEO of Checkpoint Therapeutics, concurred: "Both cosibelimab, with its dual mechanism of action, and Immuncell-LC show great promise as potential immuno-oncologic therapies. We are pleased to work in collaboration with GC Cell to determine if using the two therapies in combination may offer even greater potential benefits than being used singly."
About Immuncell-LC Immuncell-LC stands as the sole commercially approved adoptive T cell therapy for hepatocellular carcinoma adjuvant treatment. Comprising autologous, significantly expanded CIK (Cytokine Induced Killer) T lymphocytes, it has demonstrated proven efficacy in a large-scale Phase 3 clinical trial—reducing the risk of recurrence by 37% and decreasing mortality by 79% compared to the active surveillance group. Administered to over 10,000 patients in South Korea, Immuncell-LC has shown an excellent safety profile without treatment-related serious adverse events.
About Cosibelimab Cosibelimab is a potential differentiated, high affinity, fully-human monoclonal antibody of IgG1 subtype that directly binds to programmed death ligand-1 ("PD-L1") and blocks the PD-L1 interaction with the programmed death receptor-1 ("PD-1") and B7.1 receptors. Cosibelimab's primary mechanism of action is based on the inhibition of the interaction between PD-L1 and its receptors PD-1 and B7.1, which removes the suppressive effects of PD-L1 on anti-tumor CD8+ T-cells to restore the cytotoxic T cell response. Cosibelimab is potentially differentiated from the currently marketed PD-1 and PD-L1 antibodies through sustained high tumor target occupancy of PD-L1 to reactivate an antitumor immune response and the additional potential benefit of a functional Fc domain capable of inducing ADCC for potential enhanced efficacy.

Checkpoint Therapeutics' Forward-Looking Statements This press release contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended, that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, the potential differentiation of cosibelimab, including a potentially favorable safety profile as compared to the currently available anti-PD-1 therapies and the dual mechanism of action of cosibelimab translating into potential enhanced efficacy, and the potential to realize synergies and greater potential benefits in combining cosibelimab with Immuncell-LC than being used singly. Factors that could cause our actual results to differ materially include the following: the risks and uncertainties associated with the regulatory review process for cosibelimab; whether or not the U.S. Food and Drug Administration ("FDA") will determine that the cosibelimab Biologics License Application ("BLA") resubmission is complete and acceptable for review; uncertainties regarding the timeline of FDA review of the resubmitted BLA, if accepted for review; any inability to successfully work with the FDA to find a satisfactory solution to address any concerns in a timely manner or at all during the review process for the BLA, including any inability to provide the FDA with data, analysis or other information sufficient to support an approval of the BLA; our ability and the ability of our third party contract manufacturing organization ("CMO") to adequately address the issues raised in the complete response letter; any potential facility inspection or re-inspection that may be required regarding our third party CMO or otherwise; whether the FDA accepts the data and results as included in the BLA resubmission at levels consistent with the published results, or at all; our ability to execute a partnering relationship for commercialization of cosibelimab, if approved, on acceptable terms, if at all; the risk that our third-party CMO will not meet deadlines, and/or comply with applicable regulations; the risk that topline and interim data remains subject to audit and verification procedures that may result in the final data being materially different from the topline or interim data we previously published; the risk that safety issues or trends will be observed in the clinical trial when the full safety dataset is available and analyzed; the risk that a positive primary endpoint does not translate to all, or any, secondary endpoints being met; risks that regulatory authorities will not accept an application for approval of cosibelimab based on data from the Phase 1 clinical trial; the risk that the clinical results from the Phase 1 clinical trial will not support regulatory approval of cosibelimab to treat cSCC or, if approved, that cosibelimab will not be commercially successful; risks related to our chemistry, manufacturing and controls and contract manufacturing relationships; risks related to our ability to obtain, perform under and maintain financing and strategic agreements and relationships; risks related to our need for substantial additional funds; other uncertainties inherent in research and development; our dependence on third-party suppliers; government regulation; patent and intellectual property matters; competition; unfavorable market or other economic conditions; and our ability to achieve the milestones we project, including the risk that the evolving and unpredictable Russia/Ukraine conflict and COVID-19 pandemic delay achievement of those milestones.
