Study of the Bria-IMT Regimen and CPI vs Physicians' Choice in Advanced Metastatic Breast Cancer. (BRIA-ABC)
Randomized, Open-Label Study of the Bria-IMT Regimen and Check Point Inhibitor vs Physicians' Choice in Advanced Metastatic Breast Cancer.

Detailed 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 Bria-IMT regimen alone (monotherapy). After the first 150 patients have enrolled in the study, the monotherapy arm will be discontinued and patients allowed to cross over to the combination therapy if needed. Randomization will continue 1:1 between the combination therapy vs TPC.
For the Bria regimen +/- CPI arms, treatment cycles occur every 3 weeks. TPC cycle details will be according to the site's SOC. In the absence of progressive disease or major safety issues, the patient will continue with therapy cycles, with imaging assessment every 6 weeks x2 then every 8 weeks thereafter.
The Bria-IMT regimen includes:
Day -2 or -3 Cyclophosphamide 300mg/m2 Day 0 SV-BR-1-GM given intradermally divided into 4 inoculations Day 1-3 CPI infusion plus interferon intra-dermally within each Bria-IMT inoculation site

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Treatment of Physician's Choice
TPC consists of eribulin, carboplatin, capecitabine, gemcitabine, vinorelbine or taxanes in accordance with the investigators' and institutional standard of care.
The specific details of the selected regimen must include every detail of administration including frequency, sequencing (for multi-agent regimens), duration of infusion or oral administration, planned dose, dose prescribed, dose administered, dose adjustments after initial prescription or start of TPC treatment, and any other change in TPC from its initial election prior to randomization.
|
Patients in the TPC arm of the study will be treated with one or a combination of the following: carboplatin, taxanes, capecitabine, gemcitabine, vinorelbine or eribulin in accordance with the investigators and institutional standard of care.
For HER2+ patients, a HER2-targeted agent of the physician's choice can be part of TPC.
|
Experimental: Bria-IMT Regimen + CPI
The Bria-IMT regimen: Day -2 or -3 Cyclophosphamide 300mg/m2 Day 0 SV-BR-1-GM given intradermally divided into 4 inoculations Day 1-3 CPI infusion plus interferon administered intra-dermally within each SV-BR-1-GM inoculation site |
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
Other Names:
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.
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.
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.
