A patient-derived approach to cancer immunotherapy.

Innocell starts with a patient's own tumor cells. PhotonPharma is advancing the platform through clinical evaluation in recurrent epithelial ovarian cancer.

What makes the approach different.

The development rationale, and what remains to be demonstrated.

The platform

Many antigens. One patient's tumor.

Innocell uses tumor-derived cells to retain a broad antigen repertoire. Riboflavin and ultraviolet light inactivate replication; the cells are administered with CpG1018.

The intended immune response is a mechanism under evaluation, not a claim of demonstrated clinical benefit.

How Innocell works
The development program

A defined first clinical question.

The Phase 1 study at City of Hope evaluates safety and immunogenicity in recurrent epithelial ovarian cancer.

Registry record NCT06366490 was last updated March 27, 2026. Refer to the study record for current details; estimated dates are not completed milestones.

Development priorities

Clinical evidence comes first.

The lead clinical program is distinct from the planned combination cohort and potential expansion into other solid tumors. Safety, immune response and clinical benefit must be assessed in the appropriate studies.
