A Parallel-group (2-Arm), Randomized, Double-blind, 12-week Trial to Evaluate the Efficacy and Safety of MC2-25 Cream and MC2-25 Vehicle in Subjects With Chronic Kidney Disease-associated Pruritus (CKD-aP)

The purpose of this study is to access the efficacy and safety of MC2-25 cream and MC2-25 vehicle for treatment of chronic kidney disease associated pruritus (CKD)-aP).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

In this trial, subjects who fulfil all inclusion and exclusion criteria are enrolled.

Eligible subjects will be randomised in a 2:1 ratio to MC2-25 cream or MC2-25 vehicle, respectively.

The subjects will apply the assigned investigational medicinal product (IMP) twice daily for 12 weeks.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Adult males or non-pregnant females of any race or ethnicity who are ≥ 18 years of age at the time of screening
  • Has provided written informed consent
  • Chronic (>3 months) kidney disease (CKD) stages G3-G5 (i.e., estimated glomerular filtration rate [eGFR] by CKD-EPI creatinine 2021 equation <60 mL/min/1.73 m2)

  • Specifically for CKD subjects on haemodialysis (HD) or haemodiafiltration (HDF):

    1. Subjects must be established on HD or HDF 3 times per week continuously for at least 3 months prior to the start of screening and must not have plans to change from HD to HDF or vice versa during the trial
    2. Subjects who require an occasional additional HD or HDF treatment to manage fluid overload may be enrolled as long as it is anticipated that no more than 4 such treatments will be required in any given month
  • At least moderate CKD-aP defined as WI-NRS ≥4
  • Female subjects must be of either: a. Non-childbearing potential or b. Childbearing potential

Exclusion Criteria:

  • Has a functioning kidney transplant or is scheduled to receive a kidney transplant during the trial (Note: subject can be on waiting list for kidney transplant)
  • Subjects who receive peritoneal dialysis
  • In the opinion of the investigator has pruritus attributed to a cause other than CKD or its complications
  • Has localized itch restricted to the palms of the hands
  • Has concurrent skin conditions (including but not limited to pruritic dermatoses, active skin infections, ulcerations) that may limit or prevent application of MC2-25 cream or MC2-25 vehicle or that may interfere with evaluation of the effects of MC2-25 cream or MC2-25 vehicle on the skin at the Screening or Baseline visits
  • Subjects who will have skin biopsies performed must not have any known hypersensitivity to the local anaesthetic or diagnosed bleeding disorders
  • Has a concurrent or recent (within 12 months prior to screening) medical condition that, in the opinion of the investigator, could pose undue risk to the subject, impede completion of the trial procedures, or would compromise the validity of the trial measurements
  • Has a known current generalized infection (bacterial, viral, or fungal)
  • Start of a new or change to existing systemic treatment for CKD-aP
  • Use of emollients on CKD-aP areas within 10 days prior to the Baseline visit
  • Use of any topical treatment on CKD-aP areas
  • Use of any light therapy for CKD-aP
  • Use of non-biologic systemic immunosuppressive treatment
  • Use of biologic systemic treatment
  • Subjects not currently on dialysis but who are likely to initiate routine dialysis during participation in the trial

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
Mean Change in Weekly Mean Worst Itch Numeric Rating Score (WI-NRS)
Time Frame: 12 weeks
Mean change in WI-NRS score, calculated as the average of weekly means WI-NRS values from Baseline to Week 12 for MC2-25 cream compared to MC2-25 vehicle. Weekly mean WI-NRS is calculated as the average of all and at least 4 non-missing WI-NRS values recorded in the subjects' diaries for the 7 days prior to and including the scheduled in clinic visits (8 days in total expected). The WI-NRS was scored on a 11-point numeric rating scale ranging from 0 to 10, where 0=no itch and 10=worst imaginable itch.
