Description

Summary

This is a Phase 1b/2a, open-label, multi-center, dose-escalation and safety/efficacy evaluation trial of Pexa-Vec plus Cemiplimab in patients with metastatic or unresectable renal cell carcinoma (RCC). The trial consists of a dose-escalation stage, where the maximum feasible dose of Pexa-Vec in combination with Cemiplimab will be determined, followed by an expansion stage. During the expansion patients will receive Cemiplimab alone or in combination with Pexa-Vec, which will be administered either through intravenous (IV) or intratumoral (IT) injection.

Official Title

A Phase 1b/2a Dose-escalation and Safety/Efficacy Evaluation Study of Pexa-Vec (Thymidine Kinase-Deactivated Vaccinia Virus Plus GM-CSF) in Combination With Cemiplimab (REGN2810; Anti-PD-1) in Patients With Metastatic or Unresectable Renal Cell Carcinoma (RCC)

Eligibility

Open to people ages 18 years and up

  • Histologically or cytologically confirmed metastatic or unresectable clear cell renal cell carcinoma (ccRCC)
  • Part 2 Arm D ONLY: Patients must be refractory to anti PD-1 or anti-PD-L1 (either as monotherapy or in-combination with other approved checkpoint inhibitors or targeted therapies according to their approved label) and patients must meet all of the following criteria:
  • Received treatment of approved anti PD-1 or anti-PD-L1 (dosed per label of the country providing the clinical site) for at least 6 weeks. History of anti-PD-L1 only is not allowed.
  • Progressive disease after anti PD-1 or anti-PD-L1 will be defined according to RECIST 1.1. The initial evidence of progressive disease is to be confirmed by a second assessment, no less than 4 weeks from the date of the first documented progressive disease, in the absence of rapid clinical progression. (This determination is made by the Investigator; the Sponsor will collect imaging scans for retrospective analysis. Once progressive disease is confirmed, the initial date of progressive disease documentation will be considered the date of disease progression).
  • Documented disease progression within 12 weeks of the last dose of anti PD-1 or anti-PD-L1. Patients who were re-treated or on maintenance with anti-PD-1 or anti-PD-L1 will be allowed to enter the study as long as there is documented progressive disease within 12 weeks of the last treatment date.
  • Naive to systemic therapy for RCC or have progressed after, or were intolerant of, prior systemic therapy.
  • Measurable disease based on RECIST 1.1 criteria. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions
  • Karnofsky performance status of 70-100
  • Age ≥20 years old (or appropriate age of consent for the region)
  • Adequate hematological, hepatic, and renal function

You CAN'T join if...

  • Known significant immunodeficiency due to underlying illness (e.g., human immunodeficiency virus [HIV] / acquired immune deficiency syndrome [AIDS]) and/or immune-suppressive medication including high-dose corticosteroids
  • Part 2 only: Arm A,B,C: Prior treatment with any anti-cancer immunotherapy, including therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent (prior IL-2 or interferon allowed) . For Part 1: patients are excluded if they were intolerant to anti-PD-1 or anti-PD-L1 targeted therapies
  • Major surgery within 4 weeks of study treatment (minor surgical procedures are allowed)
  • Ongoing severe inflammatory skin condition requiring prior medical treatment
  • History of eczema requiring prior medical treatment
  • Tumor(s) invading a major vascular structure (e.g., carotid artery) or other key anatomical structure (e.g., pulmonary airway) OR viable central nervous system malignancy
  • Clinically significant and/or rapidly accumulating ascites, pericardial and/or pleural effusions.
  • Symptomatic cardiovascular disease, including but not limited to significant coronary artery disease (e.g., requiring angioplasty or stenting) or congestive heart failure within the preceding 12 months.
  • Asymptomatic cardiovascular disease (current or past history) unless cardiology consultation and clearance has been obtained for study participation.
  • Inability to suspend treatment with anti-hypertensive medication for 48 hours prior to and 48 hours after all Pexa-Vec treatments
  • Use of interferon/pegylated interferon (PEG-IFN) or ribavirin that cannot be discontinued within 14 days prior to any Pexa-Vec dose
  • Known active Hepatitis B or Hepatitis C
