Study of an Immunotherapeutic, DPX-Survivac, in Combination With Low Dose Cyclophosphamide & Pembrolizumab, in Subjects With Selected Advanced & Recurrent Solid Tumours

Official Title

A Phase 2, Open-label, Multicentre, Study of an Immunotherapeutic Treatment, DPX-Survivac in Combination With Low Dose Cyclophosphamide and Pembrolizumab, in Subjects With Selected Advanced and Recurrent Solid Tumours.

Summary:

This study will assess the safety and efficacy of DPX-Survivac and low dose cyclophosphamide with pembrolizumab in subjects with selected advanced and recurrent solid tumours.

Trial Description

Primary Outcome:

  • Efficacy as measured by objective response rate
  • Safety as measured by the rate of adverse events
Secondary Outcome:
  • Objective response rate
  • Duration of response
  • Disease control rate
  • Progression Free Survival
  • Overall survival
This study is a Phase 2 with safety lead-in study to assess the safety and efficacy of DPX-Survivac, low dose cyclophosphamide, and pembrolizumab combination therapy in subjects with selected advanced and recurrent solid tumours. Two ovarian cancer arms will be recruited and randomized in this study, one with and one without cyclophosphamide. All other cohorts will be single arm, receiving treatment with the triple combination. Up to 20 subjects, from any cohort, will be enrolled to assess the safety of study treatments before the study moves to the expansion phase. Once the safety lead-in is completed, the five cohorts will be expanded to recruit additional subjects following a Simon two stage design. Enrollment in the ovarian cancer cohort will be randomized 1:1 into two arms.
