Active Vitamin D and Reduced Dose Prednisolone for Treatment in Minimal Change Nephropathy (ADAPTinMCN)

January 21, 2025 updated by: University of Aarhus

Treatment of Primary Minimal Change Nephropathy: a Randomized Open-labeled Non-inferiority Study on Prednisolone and Vitamin D

Traditionally MCN is treated with a high dose of prednisolone, which induces remission in 60-90% of patients. Prednisolone treatment contains numerous side effects and the current dose is empiric. Given the lack of efficacy evidence and the risk associated with the currently accepted treatment regimen there is a need to characterize the outcome in MCN further, and to establish new, and potentially less toxic treatment regimens.

The aim is to examine if treatment with reduced dose of prednisolone in combination with activated vitamin D is as effective as standard high dose prednisolone in achieving remission and preventing relapse in MCN, and if reduced dose prednisolone is associated with fewer side effects compared to standard dose. Furthermore, the study will examine the influence of prednisolone metabolism on the efficacy and side effects of prednisolone in the treatment of MCN.

Study Overview

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
71

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

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
Remission
Time Frame: 4 to 16 weeks
Time from treatment to remission and the frequency of patients reaching remission on treatment
4 to 16 weeks

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
Relapse
Time Frame: 4 weeks to 1 year after remission
Frequency of relapse
4 weeks to 1 year after remission
Side effects to treatment
Time Frame: 4 weeks to 1 year after remission
The side effects to prednisolone are assessed using questionnaires by both patients and doctors, including SF36 and Cushing QoL. The Glucocorticoid Toxicity Index will be used to quantitate prednisolone-related morbidity.
4 weeks to 1 year after remission
Concentration of Prednisolone in saliva
Time Frame: 4 weeks after initiating prednisolone treatment
Measurement of prednisolone metabolism by saliva test and genetic analysis of specific liver enzymes
4 weeks after initiating prednisolone treatment
Rates of genetic polymorphism, including HLA variations
Time Frame: Blood test at baseline
Genomic HLA typing (HLA-class I: A, B and C and HLA-class II: DM, DO, DP, DQ and DR) will be performed to examine if specific HLA-alleles are more frequent in patients with MCN. Potential modifying genes that theoretically have pathophysiological impact on MCN will be sequenced using targeted next generation sequencing.
