Brief summary

This phase I trial studies the side effects and how well talimogene laherparepvec and panitumumab work in treating patients with squamous cell carcinoma of the skin that has spread to nearby tissues or lymph nodes (locally advanced) or other places in the body (metastatic). Talimogene laherparepvec is a type of vaccine made from a gene-modified virus that may help the body build an effective immune response to kill tumor cells. Immunotherapy with monoclonal antibodies, such as panitumumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving talimogene laherparepvec and panitumumab may work better in treating patients with squamous cell carcinoma of the skin compared to panitumumab alone.

Detailed description

PRIMARY OBJECTIVES: I. To determine the safety of the combined treatment of talimogene laherparepvec and panitumumab. II. To determine the preliminary efficacy of the combined treatment of talimogene laherparepvec and panitumumab, in comparison to single-agent panitumumab by historical control. SECONDARY OBJECTIVES: I. To assess the clinical efficacy of panitumumab in combination with intratumoral talimogene laherparepvec in terms of immune-related progression-free survival (irPFS) at 12 months, progression-free survival (PFS) hazard ratio, overall response rate (ORR), 1-year survival, overall survival (OS) and time to resectability. II. To measure the pathologic complete response rate to panitumumab combined with talimogene laherparepvec. III. Assess the response of injected and non-injected tumor deposits after panitumumab and talimogene laherparepvec. IV. Assess the time to initial response. V. Assess the durable response rate. VI. To analyze the following molecular correlates with response to therapy to confirm mechanism of action, and identify potential future targeted strategies and biomarkers of response: VIa. Mutation load in tumor tissue by next generation sequencing. VIb. Deoxyribonucleic acid (DNA) mutation signature in tumor tissue pre- and post-therapy by next generation sequencing. VIc. Messenger ribonucleic acid (mRNA) signature in tumor tissue pre-and post-therapy by Nanostring technology. VId. Immune cell populations and immune profile in pre- and post-therapy tumor tissue and peripheral blood by flow cytometry and immunohistochemistry (IHC). OUTLINE: Patients receive talimogene laherparepvec intratumorally (IM) on day 1. Patients then receive talimogene laherparepvec IM and panitumumab intravenously (IV) over 30-90 minutes on day 22. Treatment repeats every 2 weeks for up to 3 cycles in the absence of disease progression or unacceptable toxicity. Patients may receive up to 3 additional cycles of treatment per physician discretion. After completion of study treatment, patients are followed up at 30 days and then every 2 months for 2 years.
