Outcome Measures

Primary Outcomes (1)

  • Determine the Objective Response Rate (ORR) following treatment with PRGN-2009 in combination with pembrolizumab in patients with pembrolizumab-resistant recurrent or metastatic cervical cancer.

    The ORR will be calculated as the combination of subjects achieving a complete response or a partial response per RECIST v1.1. ORR will be calculated and presented with 2-sided 95% confidence interval.

    1 year

Secondary Outcomes (5)

  • Safety of PRGN-2009 in combination with pembrolizumab

    1 year

  • Progression-Free Survival (PFS) and Overall Survival (OS) following treatment with PRGN-2009 in combination with pembrolizumab

    1 year

  • Best Overall Responses (BOR) and Disease Control Rate (DCR) per RECIST v1.1 following treatment with PRGN-2009 in combination with pembrolizumab

    1 year

  • Time to Response and Duration of Responses following treatment with PRGN-2009 in combination with pembrolizumab

    1 year

  • Vector shedding following subcutaneous administration of PRGN-2009

    Up to 4 months

Study Arms (1)

PRGN-2009 plus Pembrolizumab

EXPERIMENTAL

PRGN-2009 at a dose of 5 x 10\^11 PU q3W for 3 administrations, then q6w, plus Pembrolizumab, 400mg q6w

Biological: PRGN-2009 plus Pembrolizumab

Interventions

Subjects randomized will receive PRGN-2009 (5 x 10\^11 PU, subcutaneous (SC) injection) every 3 weeks for three administrations, thereafter subjects will continue to receive PRGN-2009 administrations every 6 weeks. Pembrolizumab will be administered concurrently as intravenous (IV) infusion (400 mg) every 6 weeks.
