  • Research summary

    Anti-programmed cell death-1 (PD-1) therapies, pembrolizumab and nivolumab, are
    currently considered the standard of care for advanced melanoma in the first line
    metastatic setting. For patients who fail anti-PD-1 therapy, treatment options are limited in advanced melanoma following disease progression during or after anti-PD-1 therapy, thus it is considered an unmet medical need. Additionally, with the recent availability of checkpoint inhibitors in the adjuvant setting, it remains to be understood how patients will be treated upon progression to metastatic disease.
    This is a phase 2, open-label, single-arm, multicenter clinical trial designed to evaluate the efficacy and safety of talimogene laherparepvec (T-VEC) in combination with pembrolizumab following disease progression on prior anti-PD-1 therapy in unresectable/metastatic melanoma (stage IIIB-IVM1d) or prior anti-PD-1 therapy in the adjuvant setting.
    Subject must have received prior anti-PD-1 therapy for at least 2 to 3 consecutive cycles within an 8-week period (based on administration schedule) and have disease
    progression. Approximately 100 subjects will be enrolled into 1 of 4 cohorts based on prior anti-PD-1 experience:
    Cohort 1 – Locally Recurrent/Metastatic - Primary Resistance
    Cohort 2 – Locally Recurrent/Metastatic - Acquired Resistance
    Cohort 3 – Adjuvant Setting – Disease Free Interval < 6 months
    Cohort 4 – Adjuvant Setting – Disease Free Interval ≥ 6 months
    T-VEC and pembrolizumab are administered at a once every 3 weeks (Q3W) frequency.
    Previous studies have shown that the combination of T-VEC and pembrolizumab changed the tumor microenvironment by increasing the CD8+ T cell infiltration. This study is intended to provide additional clinical data to support the combination of
    T-VEC and pembrolizumab in patients with unresectable/metastatic IIIB-IVM1d melanoma who have progressed after receiving a checkpoint inhibitor.
