- Announced Date:
- July 15, 2024
- Indication:
- Locally Advanced Cutaneous Squamous Cell Carcinoma (cSCC)
Announcement
Checkpoint Therapeutics and GC Cell 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.
AI Summary
Checkpoint Therapeutics and GC Cell have announced a collaboration to explore the potential benefits of combining their innovative immunotherapies. The partnership will investigate cosibelimab, Checkpoint’s anti-PD-L1 antibody with a dual mechanism of action, alongside GC Cell’s Immuncell-LC, an autologous Cytokine Induced Killer (CIK) T cell therapy featuring both cytotoxic T lymphocytes and natural killer T cells. The initial studies will be conducted in vitro to determine if this combination can enhance the immune system's ability to target and destroy cancer cells. Researchers believe that cosibelimab’s ability to block PD-L1 and trigger antibody-dependent cellular cytotoxicity, when paired with the powerful T cell response from Immuncell-LC, could lead to more effective cancer treatment strategies. Positive results from these studies may pave the way for future in vivo research and clinical trials in immuno-oncology.
