Primary Outcome Measures:
  • Maximum Tolerated Dose and Percent Changes in Lean Body Mass (LBM) [ Time Frame: MTD will be assessed after the last patient in Cohort 1A and Cohort 2A complete 28 days on treatment. LBM will be assessed for comparing baseline to Week 12 ]
    To evaluate the safety, dose-limiting toxicities (DLTs), maximum tolerated dose (MTD) and pharmacokinetics of PINTA 745 and to evaluate percentage change in LBM relative to baseline at 12 weeks, via dual-energy x-ray absorptiometry(DXA) scans, in the group receiving PINTA 745 at the MTD (or if no MTD is reached, at the recommended phase 2 dose)

Secondary Outcome Measures:
  • Change in Muscle Composition - Lean Body Mass (LBM), Appendicular Lean Mass (ALM) and Mid Upper Arm Muscle Circumference (MUAMC) [ Time Frame: Baseline through Week 20 ]
    To evaluate the change in LBM and ALM via CT and dual-energy x-ray absorptiometry (DXA) scans relative to baseline at 12, 16 and 20 weeks. To evaluate change relative to baseline in MUAMC at 5, 9, 16 and 20 weeks.

  • Change in Physical Function [ Time Frame: Baseline through Week 20 ]
    To evaluate change in physical function as measured by the Stair Climbing Power Test (SCPT) and the 6 Minute Walk Test (6MWT) relative to baseline at 5, 9, 12, 16 and 20 weeks

Study Completion Date: January 2016
Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PINTA 745 Drug: PINTA 745

PINTA 745 will be administered once weekly by IV infusion.

Cohort dose schedules:

  • 3mg/kg weekly for 12 weeks
  • 3mg/kg for 3 weeks, followed by 1mg/kg for 9 weeks
  • 6mg/kg for 3 weeks, followed by 2mg/kg for 9 weeks
Placebo Comparator: Placebo Drug: Placebo

Placebo will be administered once weekly by IV infusion.

Cohort dose schedules:

  • 3mg/kg weekly for 12 weeks
  • 3mg/kg for 3 weeks, followed by 1mg/kg for 9 weeks
  • 6mg/kg for 3 weeks, followed by 2mg/kg for 9 weeks

Detailed Description:

This is a randomized (participants will be assigned by chance to study treatments), double-blind (participants and study personnel will not know the identity of the study treatments), placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial)-controlled study in patients who receive maintenance hemodialysis. Three participants will receive PINTA 745 for every participant that receives placebo. PINTA 745 or placebo will be taken intravenously once per week following dialysis.

The study period will consist of screening, treatment for 12 weeks, and follow up for 8 weeks. Evaluations will be performed to assess the safety, pharmacokinetics (study of what the body does to a drug), pharmacodynamics (study of what a drug does to the body) and effectiveness in treating protein energy wasting (such as increasing muscle size and muscle function) throughout the study.
