This is an open label, four 'cohort' study for administration of RRx-001 with autologous blood once weekly followed by or in combination with reintroduction of platinum-based doublet therapy according to the treatment schedule listed below. Small cell carcinoma and ovarian cohort participants will be randomized to 1 of 2 treatment arms, respectively. Neuroendocrine and NSCLC patients will be enrolled to single arms.~Participants with SCC will receive one of the following; RRx-001 followed by platinum doublet chemotherapy or platinum based chemotherapy alone. HGNEC, RRx-001 followed by platinum doublet chemotherapy. NSCLC, RRx-001 followed by platinum doublet chemotherapy. Participants with Platinum Refractory/Resistant Ovarian and MMMT will receive one of the following, RRx-001 followed by platinum doublet chemotherapy or chemotherapy alone.~Approximately 213 participants will be enrolled.
This study is designed to explore the potential of the epigenetic agent RRx-001 to sensitize patients who previously received and now have failed a platinum based doublet regimen. RRx-001 is administered with autologous blood once weekly followed by or in combination with reintroduction of platinum-based doublet therapy.
