Effects of PINTA 745 in End Stage Renal Disease (ESRD) Patients Who Require Hemodialysis and Have Protein Energy Wasting

April 10, 2018 updated by: Pinta Biotherapeutics

A Randomized, Double-blind, Pilot Study of PINTA 745, an Anti-myostatin Peptibody, in Patients With End Stage Renal Disease Who Require Maintenance Hemodialysis and Have Protein Energy Wasting

This is a pilot study to assess the safety, pharmacokinetics and effectiveness of PINTA 745 or placebo in treating protein energy wasting (PEW) in patients receiving maintenance hemodialysis (MHD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Study Type

Enrollment (Actual)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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)
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

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
Baseline through Week 20
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
Baseline through Week 20
