Technology

Immunophotonics is a biotech company developing a proprietary carbohydrate polymer (N-dihydrogalactochitosan or "GC").

GC's Key Highlights

  • Turns a common local tumor ablation into a systemic immunotherapy for cancer, targeting both local tumors and distant metastases
  • Potential to improve outcomes of the large number of tumor ablation procedures that are occurring on an annual basis
  • Off-the-shelf drug with low COGS, simple administration and reproducible manufacturing
  • Potential synergy with recently approved cancer immunotherapies such as anti-PD-1 and anti-CTLA4
  • GC is intended to be injected immediately (directly into the location of the ablated tumor) after an approved ablation
  • Favorable safety profile allowing potential development in both early and late stage cancers
  • Significant clinical unmet need and market opportunity

GC Transforms Local Tumor Ablation into Systemic Immunotherapy

GC is a novel compound that is intratumorally injected after local tumor destruction (such as tumor ablation), utilizing the whole repertoire of tumor associated neoantigens availabe in situ for the immune system after ablation-based immunogenic cell death. Collectively, with ablation + GC, a systemic antitumor response is initiated.

Effective Across Many Ablation Techniques

GC is procedure-agnostic as its efficacy has been demonstrated in preclinical models following treatment with a variety of ablation techniques including photodynamic therapy, thermal laser, and high intensity focused ultrasound.

Synergy with Existing Immunotherapies

Importantly, a prominent tumor-specific T-cell response induced by GC injection can prime the patient to be more responsive to downstream immuno-oncology therapies, thus ultimately, potentially improving their clinical efficacy. This is an opportunity as many immunotherapies would benefit from higher response rates. Immunophotonics plans to conduct further studies exploring alternative options of combining GC with other checkpoint inhibitors.

Immunophotonics’ Patent Coverage To Support Library of Novel Polymers

Immunophotonics is presently focused on the development of GC, it’s lead compound. In addition to GC, our core platform technology and intellectual property will allow the continued development of additional novel carbohydrate polymers for use in the cancer immunotherapy space.
