A Clinical Study of the Safety and Activity of the Investigational Cell Therapy NEO-PTC-01 in Patients With Advanced Melanoma

Part 1 will test two doses of NEO-PTC-01 and will be structured according to a 3+3 dose escalation design. After the highest tolerated NEO-PTC-01 dose is identified, 2 additional evaluations in Part 1 are planned to investigate the combination of NEO-PTC-01 with either interleukin (IL) 2-directed or programmed cell death protein 1 (PD-1) inhibitor therapy, respectively.

Part 2 will test the dose deemed to be safe in the dose-finding part of the study to further define the safety of NEO-PTC-01 in patients currently receiving PD-1/ programmed death ligand 1 (PD-L1) inhibitors (as single agent or in combination with cytotoxic T-lymphocyte-associated antigen-4 \[CTLA4\] inhibitors) as first line therapy for metastatic melanoma.

Patients who were treated on previous protocol versions and left the study due to disease progression or who have completed the 52-week follow-up period, may re-enter the study for an extended 5-year follow up in which additional assessments will be conducted.
