Phase II

A Phase 2 Study of Cemiplimab, an Anti-PD-1 Monoclonal Antibody, and ISA101b Vaccine in Patients With Recurrent/Metastatic HPV16 Cervical Cancer Who Have Experienced Disease Progression After First Line Chemotherapy

  • Study HIC#:2000029247
  • Last Updated:04/01/2022

The primary objective of the study is to estimate the clinical benefit of cemiplimab + ISA101b after progression on first line chemotherapy, as assessed by objective response rate (ORR).

  • Age18 years and older
  • GenderFemale only
  • Start Date03/29/2022
  • End Date10/22/2024

Trial Purpose and Description

The secondary objectives of the study are:

  • To characterize the safety profile of cemiplimab + ISA101b
  • To assess preliminary efficacy of cemiplimab + ISA101b as measured by duration of response (DOR), progression-free survival (PFS), and overall survival (OS)

Eligibility Criteria

Key Inclusion Criteria:

  1. Adult patients ≥18 years of age (or the legal age of adults to consent to participate in a clinical study per country specific regulations).
  2. Has histologically confirmed recurrent or metastatic HPV16 positive cervical cancer as determined by an investigational HPV16 PCR assay, who have experienced disease progression after treatment with platinum containing therapy as defined in the protocol
  3. Patient must be determined to be positive for HPV16 genotype, as determined by a specified central reference laboratory.
  4. Patient must have measurable disease as defined by RECIST 1.1.
  5. Must have received prior bevacizumab and taxol unless meets pre-specified protocol criteria
  6. ECOG performance status of 0 or 1.
  7. Has adequate organ and bone marrow function as defined in the protocol.
  8. Anticipated life expectancy ≥20 weeks.

Key Exclusion Criteria:

  1. Prior treatment with an agent that blocks the PD-1/PD-L1 pathway.
  2. Prior treatment with other systemic immune-modulating agents as defined in the protocol
  3. Major surgery or radiation therapy within 14 days of first administration of study drug
  4. Has received treatment with an approved systemic therapy within 4 weeks of first dose of study drug, or has not yet recovered (ie, grade ≤1 or baseline) from any acute toxicities except for laboratory changes as described in the protocol
  5. Has another malignancy that is progressing or requires active treatment and/or history of malignancy other than cervical cancer within 3 years of date of first planned dose of study drug as defined in the protocol
  6. Has any condition that requires ongoing/continuous corticosteroid therapy (>10 mg prednisone/day or anti-inflammatory equivalent) within 4 weeks prior to the first dose of study drug. 7. Has ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments as defined in the protocol
