Details and patient eligibility

About

To estimate the clinical benefit of cemiplimab monotherapy versus cemiplimab in combination with RP1 for patients with locally advanced or metastatic CSCC, as assessed by overall response rate (ORR) and complete response rate (CRR) according to blinded independent review.

Full description

RP1 is a selectively replication competent herpes simplex virus type 1(HSV-1). This is a Phase 1/2, open-label, multicenter repeat-dosing study of RP1 alone and in combination with nivolumab in patients with advanced malignancies, and contains both single agent dose escalation, dose expansion to include nivolumab, and the combination in multiple Phase 2 cohorts in individual tumor types.

Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Histologically confirmed locally advanced or metastatic cutaneous squamous cell carcinoma
  • Patients with locally advanced disease who are not suitable candidates for surgical or radiological treatment of lesions or have refused those treatments
  • At least 1 lesion that is measurable and injectable by study criteria
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤1. Patients with ECOG PS 2 at baseline may be allowed to enroll if PS 2 status is only related to the CSCC disease under study
  • Anticipated life expectancy >12 weeks
  • All patients must consent to provide archived or newly obtained tumor material for central pathology review for confirmation of diagnosis of CSCC.

Key Exclusion Criteria:

  • Prior treatment with an oncolytic therapy
  • Patients with active significant herpetic infections or prior complications of HSV-1 infection (e.g. herpetic keratitis or encephalitis)
  • Patients who require intermittent or chronic use of systemic (oral or intravenous) anti-virals with known anti-herpetic activity (e.g. acyclovir)
  • Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments
  • Prior treatment with an agent that blocks the PD-1/PD-L1 pathway.
  • Prior treatment with other immune modulating agents other than as adjuvant or neoadjuvant therapy within 3 years.
  • Untreated brain metastasis(es) that may be considered active.
  • Acute or chronic active hepatitis B or known history of hepatitis B or hepatitis C or human immunodeficiency virus (HIV) infection
  • History of ILD/pneumonitis within the last 5 years or a history of ILD/pneumonitis requiring treatment with systemic steroids.
  • Any major or surgical procedure ≤ 28 days before randomization
  • Administration of live vaccines ≤ 28 days before randomization

Note: Other protocol defined Inclusion/Exclusion criteria apply.
