Randomized, Open-Label Study of the Bria-IMT Regimen and Check Point Inhibitor vs Physicians' Choice in Advanced Metastatic Breast Cancer.
BriaCell Therapeutics Corporation
Summary
This is a multicenter randomized, open label study to evaluate overall survival with the Bria-IMT regimen in combination with Checkpoint Inhibitor \[Retifanlimab\], versus Treatment of Patients'/Physicians' Choice (TPC) in advanced metastatic or locally recurrent breast cancer (aMBC) patients with no approved alternative therapies available.
Description
This is a multicenter randomized, open label study to evaluate overall survival with the Bria-IMT regimen in combination with Checkpoint Inhibitor \[Retifanlimab\], versus Treatment of Patients'/Physicians' Choice (TPC) in advanced metastatic or locally recurrent breast cancer (aMBC) patients with no approved alternative therapies available. A secondary objective will be to evaluate the activity of the Bria-IMT regimen alone in comparison with the Bria-IMT regimen in combination with CPI. Initial randomization will be 1:1:1 to the Bria-IMT regimen + CPI (combination therapy), TPC, and the Bri…

Interventions
- BiologicalSV-BR-1-GM
SV-BR-1-GM is an experimental, allogeneic, whole cell breast tumor cell line stably transfected with the CSF2 gene (encoding GM-CSF) to secrete GM-CSF in vivo to consequently augment dendritic cell activity
- DrugCyclophosphamide
Cyclophosphamide is an alkylating agent with indications for treatment of malignant diseases including breast cancer. Cyclophosphamide (Cytoxan) 300 mg/m2 I.V., single dose, will be given to patients assigned to the SV-BR-1-GM. Cyclophosphamide will be administered 2-3 days prior to SV-BR-1-GM inoculations.
- DrugInterferon infiltration of the inoculation site
Interferon is a cytokine released by cells to regulate immune responses to viral infections. For this study, 0.1 mcg Pegasys per injection site (x 4 injection sites) will be administered.
- DrugRetifanlimab
Retifanlimab is a checkpoint inhibitor. A total dose of 375mg will be administered at first cycle on or about day +2 (+/-1d). In all other cycles, Retifanlimab is permitted to be administered between Day -2/-3 to Day 2±1 of the cycle based on the convenience of the patients and the clinical sites. However once the timing of the CPI is chosen for C1, it must be given on the same day thereafter throughout the trial.
