DPX-Survivac and Pembrolizumab With and Without Intermittent Low-Dose Cyclophosphamide, in Subjects With Relapsed/Refractory Diffuse Large B-Cell Lymphoma (VITALIZE) Phase 2 102 Randomized Open-Label
This is a Phase 2b, randomized, open label study to assess the safety and efficacy of DPX-Survivac and pembrolizumab, with and without low-dose cyclophosphamide (CPA) in subjects with relapsed or refractory DLBCL.
The study will enroll up to 102 subjects. Eligible subjects will be randomized (1:1) to receive:
- Arm 1: DPX-Survivac, pembrolizumab and intermittent, low-dose CPA; or,
- Arm 2: DPX-Survivac and pembroli...

| Participant Group/Arm | Intervention/Treatment |
|---|---|
ExperimentalArm 1: DPX-Survivac, pembrolizumab, CPA Subjects will receive two 0.5 mL doses of DPX-Survivac three weeks apart followed by up to twelve 0.1 mL doses eight weeks apart. Pembrolizumab will be administered on the first day of every three week cycle at a flat dose of 200 mg. CPA will be self-administered 50 mg BID for 7 days on and 7 days off starting on D0. | DPX-Survivac SC injection on D7 and D28, then every 8 weeks Pembrolizumab IV infusion every 3 weeks CPA 50 mg twice daily, week on then week off |
ExperimentalArm 2: DPX-Survivac, pembrolizumab Subjects will receive two 0.5 mL doses of DPX-Survivac three weeks apart followed by up to twelve 0.1 mL doses eight weeks apart. Pembrolizumab will be administered on the first day of every three week cycle at a flat dose of 200 mg. Subjects randomized to Arm 2 will not receive CPA. | DPX-Survivac SC injection on D7 and D28, then every 8 weeks Pembrolizumab IV infusion every 3 weeks |

Changes in Patient Reported Outcomes using the FACT-Lym Assessment | The FACT-Lym is a validated questionnaire that consists of a 27-item general core questionnaire (i.e., Functional Assessment of Cancer Therapy - General \[FACT-G\]) and a 15-item disease-specific questionnaire (Lymphoma Subscale). | Approximately 24 months |
Changes in Patient Reported Outcomes using the EQ-5D-5L Assessment | The EQ-5D-5L is a 5-item measure that can be used to describe and value current overall health consisting of 5 items assessing mobility, self care, usual activities, pain/discomfort, and anxiety/depression. | Approximately 24 months |
