RRx-001, a novel oxidizing and epigenetic agent, has shown promise as a single agent in a Phase I trial and is currently in Phase II trials, both alone and in combination with immunotherapy (Nivolumab), chemotherapy and radiation therapy. These results demonstrate that inhibition of the

PD-1/PD-L1 axis in combination with RRx-001 can significantly increase the CR rate in a preclinical model of myeloma. Experiments are ongoing to optimize this treatment regimen, study the effects of the combined treatment on the tumor immune microenvironment, and the study of the efficacy of this combined therapy in other tumor types. Results from this ongoing work will be presented, and have near-term translational potential.


Current clinical data from a Phase 2 study in Colorectal Cancer (CRC) will be used to demonstrate the use of stochastic modeling in testing the resensitization hypothesis. The following items will be discussed:

1. CRC stochastic models.

2. Statistical analysis of clinical CRC data.

3. Illustration of challenges & potential solutions.

4. Translational potential conclusion, discussion & future work directions.
