Brief Summary:
The purpose of this study is to determine the maximum tolerated dose of RX-0201, up to a target dose of 250 mg/m^2/day, when given in combination with everolimus (Stage 1), and to assess the safety and efficacy of RX-0201 plus everolimus, in subjects with metastatic renal cell cancer (Stage 2).

Condition or disease Intervention/treatment Phase
Metastatic Renal Cell Cancer Drug: RX-0201 Phase 1 Phase 2

Detailed Description:
This multi-center, open-label, randomized, parallel group study of RX-0201 in combination with everolimus, versus everolimus alone to treat subjects with advanced renal cell carcinoma will be conducted in 2 stages. Stage 1 will be an open-label, dose-escalation study of RX-0201 to identify a safe and tolerable dose of RX-0201 up to a target dose of 250 mg/m^2/day when given in combination with everolimus. Stage 2 will be a randomized, open-label, 2-arm study of RX-0201 in combination with everolimus versus everolimus alone. Subjects will receive RX-0201, at the dose identified in Stage 1, in combination with everolimus or everolimus alone, for up to 8 cycles to determine safety and efficacy of the combination.

Arm Intervention/treatment
Experimental: RX-0201 plus everolimus (Stage 1 & 2)
RX-0201 and everolimus will be taken together as described in the Interventions description.
Drug: RX-0201

RX-0201 will be administered in a dose up to 250mg/m^2/day as a continuous infusion for a cycle of 21 days (14 days infused followed by 7 days off) for up to 8 cycles in Stage 1.

In Stage 2, RX-0201 will be administered the dose determined in Stage 1 as a continuous infusion for a cycle of 21 days (14 days infused followed by 7 days off) for up to 8 cycles.

Other Name: Archexin




Primary Outcome Measures :
  1. Incidence of dose-limiting toxicities (DLTs) (Stage 1) [ Time Frame: after 1 cycle (3 weeks) of treatment with RX-0201 and everolimus ]
    Incidence of adverse events and clinical laboratory abnormalities defined as dose-limiting toxicities

  2. Progression Free Survival (Stage 2) [ Time Frame: 4 months of treatment with RX-0201 and everolimus ]

Secondary Outcome Measures :
  1. Area under the plasma concentration versus time curve (AUC) of RX-0201 (Stage 1) [ Time Frame: predose, 1, 2, 3, 4, 6, and 24 hours after start of Cycle 1 RX-0201 infusion, and then immediately prior to the end of Cycle 1 infusion (Day 15), 1, 2, 3, 4, 6, and 24 hours after infusion is stopped ]
  2. Incidence of adverse events, changes in clinical laboratory tests and vital signs over time (Stage 1 and Stage 2) [ Time Frame: up to 24 weeks of treatment with RX-0201 plus everolimus and at least 30 days of safety follow up ]
  3. Changes in tumor size [ Time Frame: Baseline and at weeks 6, 12, 18, and 24 ]

Other Outcome Measures:
  1. Biomarker concentrations in blood [ Time Frame: Baseline and at weeks 6, 12, 18, and 24 ]
  2. RX-0201 concentration in the blood (Stage 2 only) [ Time Frame: After 2 weeks of treatment ]
