A Phase II Study of Combining Talimogene Laherparepvec T-VEC (NSC-785349) and MK-3475 (Pembrolizumab) (NSC-776864) in Patients With Advanced Melanoma Who Have Progressed on Anti-PD1/L1 Based Therapy

This phase II trial studies how well talimogene laherparepvec and pembrolizumab work in
treating patients with stage III-IV melanoma. Biological therapies, such as talimogene
laherparepvec, use substances made from living organisms that may stimulate or suppress the
immune system in different ways and stop tumor cells from growing. Monoclonal antibodies,
such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread.
Giving talimogene laherparepvec and pembrolizumab may work better in treating patients with
melanoma by shrinking the tumor.

PRIMARY OBJECTIVES:

I. To evaluate the durable response rate of treatment with talimogene laherparepvec (T-VEC)
in combination with MK-3475 (pembrolizumab) following progression on prior anti-PD-1 or
anti-PD-L1 therapy alone or in combination with other agents different from T-VEC.

SECONDARY OBJECTIVES:

I. To estimate the objective response rate (confirmed and unconfirmed, complete and partial
responses) in the injected lesions.

II. To estimate the objective response rate (ORR) in the non-visceral, non-injected lesions.

III. To estimate the objective response rate (ORR) in the visceral lesions (Cohort A).

IV. To estimate the overall objective response rate (ORR). V. To estimate the median
progression-free survival (PFS). VI. To estimate the median overall survival (OS). VII. To
evaluate the toxicity of the regimen.

TERTIARY OBJECTIVES:

I. To evaluate whether adding T-VEC to PD1 blockade can increase T-cell infiltration into
tumors and whether change in T-cell infiltration is associated with response.

II. To evaluate whether adding T-VEC to PD1 blockade can increase T-cell receptor (TCR)
clonality in tumors and in peripheral blood and whether increased TCR clonality is associated
with response.

III. To evaluate whether intra-tumoral injection of T-VEC is associated with the tumor immune
microenvironment.

IV. To evaluate whether tumor mutational load and mutations in the IFN pathway is associated
with response to T-VEC plus MK-3475 (pembrolizumab) therapy in the anti-PD1/L1 therapy
refractory melanoma patients.

OUTLINE:

Patients receive talimogene laherparepvec intralesionally (IL) and pembrolizumab
intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 18
courses for talimogene laherparepvec and 36 courses for pembrolizumab in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for up to 2
years and then annually for a total of 5 years.
