Description of intervention(s) / exposure
Treatment: Drugs - Talimogene laherparepvec
Treatment: Drugs - Pembrolizumab

Experimental: Cohort 1 - Locally Recurrent/Metastatic - Primary Resistance - Includes participants who received anti-PD1 therapy in the locally recurrent/metastatic setting and experienced a best overall response of disease progression or stable disease prior to confirmed disease progression.
Participants will receive talimogene laherparepvec at an initial dose of up to 4.0 mL of 10^6 plaque-forming units (PFU)/mL on Day 1. Subsequent doses of up to 4.0 mL of 10^8 PFU/mL will be administered every 3 weeks for up to 35 cycles in total. Participants will also receive pembrolizumab at a dose of 200 mg every 3 weeks for up to 35 cycles.

Experimental: Cohort 2 - Locally Recurrent/Metastatic - Acquired Resistance - Includes participants who received anti-PD-1 therapy in the locally recurrent/metastatic setting and experienced confirmed disease progression following a complete or partial response on anti-PD-1 therapy.
Participants will receive talimogene laherparepvec at an initial dose of up to 4.0 mL of 10^6 plaque-forming units (PFU)/mL on Day 1. Subsequent doses of up to 4.0 mL of 10^8 PFU/mL will be administered every 3 weeks for up to 35 cycles in total. Participants will also receive pembrolizumab at a dose of 200 mg every 3 weeks for up to 35 cycles.

Experimental: Cohort 3 - Adjuvant Setting -Disease Free Interval < 6 months - Includes participants who received anti-PD-1 therapy in the adjuvant setting and experienced confirmed disease progression following a disease-free interval of < 6 months after starting the adjuvant anti-PD-1 therapy.
Participants will receive talimogene laherparepvec at an initial dose of up to 4.0 mL of 10^6 plaque-forming units (PFU)/mL on Day 1. Subsequent doses of up to 4.0 mL of 10^8 PFU/mL will be administered every 3 weeks for up to 35 cycles in total. Participants will also receive pembrolizumab at a dose of 200 mg every 3 weeks for up to 35 cycles.

Experimental: Cohort 4 - Adjuvant Setting -Disease Free Interval = 6 months - Includes participants who received anti PD-1 therapy in the adjuvant setting and experienced confirmed disease progression following a disease-free interval of = 6 months after starting the adjuvant PD-1 inhibitor.
Participants will receive talimogene laherparepvec at an initial dose of up to 4.0 mL of 10^6 plaque-forming units (PFU)/mL on Day 1. Subsequent doses of up to 4.0 mL of 10^8 PFU/mL will be administered every 3 weeks for up to 35 cycles in total.

- Subjects must not have history or evidence of symptomatic autoimmune
glomerulonephritis, vasculitis, or other symptomatic autoimmune disease, or active
autoimmune disease or syndrome requiring systemic treatment in the past 2 years (ie,

immunosuppression.

- Subjects may not have been previously treated with talimogene laherparepvec or any
other oncolytic virus.

Summary
Brief summary
This is a phase 2, open-label, single-arm, multicenter clinical trial designed to evaluate
the efficacy and safety of talimogene laherparepvec in combination with pembrolizumab
following disease progression on prior anti-programmed cell death protein (anti-PD-1) therapy
in unresectable/metastatic melanoma (stage IIIB-IVM1d) or prior anti-PD-1 therapy in the
adjuvant setting. Subjects will be treated with talimogene laherparepvec and pembrolizumab
until confirmed complete response, disappearance of all injectable lesions, documented
confirmed disease progression per modified immune-related Response Criteria simulating
Response Evaluation Criteria in Solid Tumors (irRC-RECIST), intolerance of study treatment,
or 102 weeks from the first dose of talimogene laherparepvec and/or pembrolizumab, whichever
occurs first.
