This study is currently in Phase 2 and is for patients with a diagnosis of Stage IIIb-IV unresectable melanoma, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) solid tumors, non-melanoma skin cancer (NMSC), and non-small cell lung cancer (NSCLC).

Key eligibility criteria

You may be eligible for this study if you meet the following conditions:
• Are capable of giving signed informed consent which includes willingness to comply with the requirements and restrictions listed in the informed consent form.
• Are at least 18 years old.
• Have at least 1 measurable tumor of ≥1 cm in longest diameter (or ≥1.5 cm shortest diameter for lymph nodes) and injectable lesions which in aggregate comprise ≥ 1 cm in longest diameter.
• Have a life expectancy of at least 3 months.
• Have not received prior treatment with an oncolytic virus therapy.
• Have no acute or chronic active hepatitis B and C virus infection, nor known history of hepatitis B, nor known active hepatitis C virus, nor HIV infection.

• Have no history of interstitial lung disease.

What to expect during the study

The Phase 2 portion of this study is still enrolling the following two cohorts:
• Anti-PD-1 failed NMSC
• MSI-H or dMMR

Dosing of RP1 will start on Day 1 and will be administered every two weeks for up to eight cycles (approximately 4 months). After the first dose of RP1, dosing will be given with concurrent nivolumab infusion every two weeks followed by dosing every four weeks for up to an additional twenty months.

Patients may also receive additional courses of RP1 if they meet the protocol specified criteria for RP1 dose re-initiation.
