Effect of Pirfenidone on Glomerular Filtration Rate and Albuminuria in Patients With Diabetic Nephropathy

March 13, 2023 updated by: Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran
It is estimated that approximately 30% of patients with diabetes develop diabetic nephropathy. Diabetic nephropathy is a multifactorial progressive disease that occurs through various mechanisms such as hyperglycemia, oxidative stress, inflammation and fibrosis, control or blocking these mechanisms are therefore potential therapeutical targets for this entity. Current treatment options are based on the glycemic control, blood pressure control, as well as the use of medications such as angiotensin-converting enzyme inhibitors and Angiotensin II receptor antagonists, these actions are not enough to stop progression. Pirfenidone is a drug with antifibrotic, antioxidant, and anti-inflammatory properties. Although the specific mechanism is unknown, pirfenidone interferes with the expression, secretion and the effect of the β (TGF-β) transforming growth factor. The investigators plan to carry out a controlled clinical study to evaluate the effect of pirfenidone in patients with type 2 diabetes and nephropathy. The period of time the treatment will be administered will be of 12 months, 62 patients will be included. The primary outcome will be improvement in glomerular filtration rate. The secondary outcomes will be number of patients requiring replacement therapy, 24 hour urine microalbuminuria and change in the concentration of TGF - β. Change in these parameters will be evaluated at the end of the treatment period (12 months). Throughout the study the incidence of adverse events will be recorded, wich will allow us to learn about the safety and security of the drug in this population.

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.

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

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
Time Frame
Effect of oral pirfenidone (1800 mg) in albuminuria
Time Frame: 12 months

12 months

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.
