Colchicine to Suppress Inflammation and Improve Insulin Resistance in Adults and Adolescents With Obesity

Description

Background: About 40 percent of adults and 20 percent of adolescents in the U.S. have a body mass index over 30 kg/m2. Being overweight may lead to a state of low-level inflammation. This may cause health problems. Researchers want to see if an anti-inflammatory medicine can help. Objective: To learn if colchicine can improve metabolism in people who have high body weight, increased inflammation, and high insulin in the blood but who have not yet developed high blood sugar. Eligibility: People aged 12 and older with high body weight who may have increased inflammation and high insulin in the blood. Healthy adult volunteers are also needed. Design: Participants will be screened with the following: Medical history Physical exam Fasting blood tests Urine tests Electrocardiogram Dual energy x-ray absorptiometry (They will lie on a table while a camera passes over their body.) Stool sample and 24-hour food diary (optional) Participants will have 3 study visits and 3 phone check-ins. At visits, they will repeat some screening tests. Healthy volunteers will have the baseline visit only. They will not get the study drug. At the baseline visit, participants will have an Oral Glucose Tolerance Test (OGTT). For this, they will drink a sweet liquid and then give blood samples. They will get a 12-week supply of the study drug or placebo to take daily by mouth. Participants will have study visits 6 weeks and 12 weeks after they started taking the study drug. At the 12-week visit, they will repeat the OGTT. Participation will last for 3 (Omega) to 4 months. ...

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Individuals with significant medical comorbidities (e.g., NYHA Class III or IV heart failure, or CKD Stage 3b or worse (eGFR \< 60 mL/min/1.73 m2), or American Society of Anesthesiologists Physical Status Class 3 or above) or other serious disorders at the discretion of the investigators.
  • 2. HbA1c \> 7.0%
  • 3. Type 2 diabetes mellitus, as determined by either having:
  • 1. clear clinical diagnosis of diabetes, such as a patient in a hyperglycemic crisis or classic symptoms of hyperglycemia and a random plasma glucose \>= 200 mg/dL
  • 2. two of the following three:
  • 4. Recent or regular use of colchicine, anorexiant, or diabetic medications in the last 3 months, or plan to start in the following 3 months.
  • 5. Recent or regular use of anti-inflammatory medications (e.g. prednisone, NSAIDs) in the last 7 days, or plan to start in the following 3 months.
  • 6. Current use of a strong or moderate CYP3A4 inhibitor or P-glycoprotein (P-gp), as this may cause a significant increase in colchicine plasma concentrations and risk for side effects. Oral contraceptive use will be permitted, provided the contraceptive has been used for at least two months before starting study medication. Note: HMA-CoA reductase inhibitors ( statins ) in adults only will also be
  • 7. Known allergy to colchicine.
  • 8. Previous history of agranulocytosis, gout, or significant myositis.
  • 9. Females who are pregnant, planning to become pregnant, currently nursing an infant, or have irregular menses, defined as cycles less than 21 days or greater than 45 days in premenopausal women.
  • 10. Individuals who have current substance abuse or a DSM 5 Axis I psychiatric disorder or DSM Axis II Mental Retardation diagnosis that in the opinion of the investigators would impede competence, compliance, or participation in the study.
  • 11. Current users of tobacco or nicotine (e.g., nicotine patch, e-cigarettes) products.
  • 12. Participation in a formal weight loss program (e.g., Weight Watchers) or recent weight change of more than 3% of body weight in the past two months.
