Study of Nicotine Patches in Patients With Sarcoidosis

November 1, 2021 updated by: Elliott Crouser MD

Modulation of Pulmonary Sarcoidosis by Nicotinic Acetylcholine Receptors

The purpose of this study is to compare peoples with disease (sarcoidosis) to those without disease. We want to see if people with sarcoidosis have a different immune response to those people without disease.

The goal of this study is to see if the nicotine patch is an anti-inflammatory treatment for sarcoidosis.

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

Until recently, there was no good explanation for the fact that smoking cigarettes actually reduces the risk of sarcoidosis. Research studies have shown that the nicotine, a common component of cigarette smoke, strongly suppresses the immune system and reduces the type of inflammation that is characteristic of sarcoidosis in the lungs. We propose that nicotine treatment, administered in the form of a skin patch, will reduce the severity of lung disease in patients with sarcoidosis. Sarcoidosis patients who volunteer to participate in this study will submit standardized questionnaires relating to their quality of life and the severity of their shortness of breath before and after treatment. We will also compare objective measures of lung function, radiographic parameters, and the severity of lung inflammation. We predict that nicotine treatment will reduce the severity of sarcoidosis symptoms, improve lung function, and resolve lung inflammation. If our hypothesis is proven to be correct in this relatively small group of patients, we will perform additional studies in a larger group of patients and will consider the features of sarcoidosis patients that predict a favorable response to nicotine and other nicotine-like drugs. If nicotine is ultimately found to be an effective treatment for sarcoidosis, it may replace some of the existing treatments which are frequently ineffective and have unacceptable side-effects.

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.
64

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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • • Symptomatic (active) granulomatous lung disease (radiographic stage II or III disease) at least 6 months after the diagnosis. This selects patients that have the chronically active variant of sarcoidosis and will likely require long-term treatment (33).

Exclusion Criteria:

  • • Active smokers,

    • Previous splenectomy,
    • Those requiring high-dose immunosuppression [i.e., ≥ 0.2 mg/kg/day prednisone (or equivalent) or > 10 mg/week methotrexate or requires second line cytolytic agents (e.g., cyclophosphamide, azathioprine) or anti-TNF treatments (e.g., thalidomide, anti-TNF antibodies, etc.)] to control disease activity.
    • We will also exclude patients at high risk of complications relating to the use of nicotine. This will include patients with a known intolerance of nicotine or those with active cardiac or central nervous system disease who are at higher risk of cardiac arrhythmias or seizures.
    • We will also exclude patients with extensive pulmonary fibrosis based upon lung biopsy or high resolution CT scan criterion

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
To determine if nicotine treatment reduces lung inflammation.
Time Frame: 3 months
Normalization of immune response
3 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.
Outcome Measure
Measure Description
Time Frame
To determine if expression of α7 nAChR on monocytes/macrophages derived from the blood/lungs correlates with the severity of pulmonary sarcoidosis.
