Brief Summary

Background: \- Being overweight may cause low-level inflammation. This inflammation may cause some of the medical problems of obesity, like high blood sugar (diabetes) and heart disease. This study will test whether a medication called colchicine can improve metabolism in adults who are overweight but have not yet developed diabetes. Objectives: \- To learn whether colchicine improves sugar regulation and metabolism. Eligibility: \- Healthy overweight adults18 to 100 years old. Design:

  • Participants must fast before each visit, including the screening visit.
  • Participants will be screened with blood tests,urine tests, medical history, and physical exam. They will have to drink sugar water, and have blood drawn to find out if they are healthy.
  • For visit 1, participants will have a medical history and physical exam and answer questions. They will have blood taken with an intravenous (IV) line, give urine sample, and give 2 stool samples..
  • Also, subjects will get sugar water through one IV. Blood will be drawn from the other. This measures sugar and insulin levels. During this, participants will lie in a bed and can watch TV.
  • Participants will have a full-body X-ray, lying on a table while a camera passes over them. They will also have an abdominal CT scan, lying on a table that moves through a ring that takes pictures.
  • Participants will have a small fat tissue sample taken from their abdomen. It is like getting a mini-liposuction.
  • Participants will be given the study drug or placebo. They will take it twice daily for 3 months.
  • For visit 2, participants will have blood tests, urine tests, medical history, and physical exam.
  • For visit 3, participants will repeat the tests in visit 1.

Outcome Measures

Primary Outcomes (1)

  • Change in Insulin Sensitivity From FSIVGTT

    Change (3 month minus minus baseline) in insulin sensitivity value, calculated from frequently-sampled intravenous glucose tolerance tests by Bergman's Minimal Model using intent-to-treat. Higher values represent a better outcome. There are no data from the evaluation-only participants, since they were not followed longitudinally.

    Baseline to 3 months

Secondary Outcomes (2)

  • Change in HOMA-IR Index

    Baseline to 3 months

  • Changes in C-reactive Protein

    Baseline to 3 months

Study Arms (6)

Obese Adults with Metabolic Syndrome Randomized to Placebo

EXPERIMENTAL

Experimental treatment with placebo capsules identical in appearance to the experimental colchicine preparation

Drug: Placebo capsules given

Obese Adults with Metabolic Syndrome Randomized to Colchicine

EXPERIMENTAL

Experimental treatment with colchicine capsules identical in appearance to the experimental placebo preparation

Drug: Colchicine 0.6Mg Cap

Diet-controlled Type 2 Diabetes Adults Assigned to Colchicine

EXPERIMENTAL

Participants with Diet-controlled Type 2 Diabetes who were assigned to Open-label treatment with colchicine. These participants were not randomized and were not part of the randomized controlled trial.

Drug: Colchicine 0.6Mg Tab

Evaluation Only Non-obese Adults

NO INTERVENTION

Participants without obesity seen only for the evaluation component of the study. Such participants are a control group for cross-sectional analyses of baseline data from the experimental cohort.

Evaluation Only Obese Adults Not Randomized

NO INTERVENTION

Participants with obesity seen only for the evaluation component of the study. Such participants are a control group for cross-sectional analyses of baseline data from the experimental cohort. These participants were found not eligible for randomization.

Evaluation Only Adults with Type 2 Diabetes

NO INTERVENTION

Participants with Diet-controlled Type 2 Diabetes seen only for the evaluation component of the study. Such participants are a control group for cross-sectional analyses of baseline data from the experimental cohort.

Eligibility Criteria

Age18 Years - 100 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects will qualify for randomization to colchicine or placebo if they meet the following criteria:
  • Good general health. In general subjects should take no medications. However, individuals taking medications for obesity-related co-morbid conditions, who have not had changes in dosage for more than 3 months, may be included, at the discretion of the principal investigator.
  • Obesity, defined as a body mass index (BMI) greater than or equal to 30 kg/m\^2, but weight less than 450 lbs in order for subjects to undergo Dual-Energy X-ray Absorptiometry (DXA) scanning.
  • Age 18 to 100 years.
  • Metabolic Syndrome defined as any 3 of the following 5:
  • FPG greater than or equal to 100 mg/dl, or Impaired Glucose Tolerance (Glucose greater than or equal to 140 mg/dl at 2 hours of OGTT)
  • Triglycerides greater than or equal to 150 mg/dl, or on treatment
  • Waist Circumference: Men greater than or equal to 40 in (greater than or equal to 102 cm); Women greater than or equal to 35 in (greater than or equal to 88 cm)
  • Reduced HDL-C: Men \< 40 mg/dl; Women \< 50 mg/dl, or on treatment
  • Hypertension: greater than or equal to 130 mmHg systolic, or greater than or equal to 85 mmHg diastolic, or on treatment
  • HOMA-IR greater than or equal to 2.6. Our goal is to enroll participants who have pre-existing insulin resistance.
  • high sensitivity C-reactive protein (hs-CRP) greater than or equal to 2.0 mg/L. We aim to recruit participants with increased baseline level of inflammation. Individuals with hsCRP above 2.0 mg/L have been shown to have an increased risk for cardiovascular events.

You may not qualify if:

  • Type 2 diabetes mellitus, as determined by either having:
  • Clear clinical diagnosis of diabetes, such as a patient in a hyperglycemic crisis or classic symptoms of hyperglycemia and a random plasma glucose greater than or equal to 200 mg/dL
  • Two of the following three:
  • Fasting plasma glucose greater than or equal to 126 mg/dL
  • Hemoglobin A1c greater than or equal to 6.5%
  • An oral glucose tolerance test glucose concentration of greater than or equal to 200 mg/dL at 2 hours.
  • One of the above three criteria (bi.-biii.) meeting the T2DM cutoff on two different days. If only one of the above three criteria (bi.-biii.) meet the T2DM threshold during the Screening Visit, that test will be repeated on another day to determine if the subject has T2DM or not. As per ADA guidelines, The diagnosis \[of T2DM\] is made on the basis of the confirmed test.Moreover, because HbA1c has been shown to be higher in African Americans (AA) as compared to other races for the same glycemia, non-diabetic AA may be unfairly excluded by their HbA1c alone. Therefore, for AA subjects, if their 2 hour OGTT and fasting glucoses are in the non-diabetic range, and the HbA1c is \< 7.0%, we will consider them non-diabetic.
  • Presence of a significant active or chronic illness likely to limit life span and/or increase risk of intervention, including renal (GFR less than or equal to 60 ml/min/1.73m2), cardiovascular, hepatic (other than obesity-related steatosis), gastrointestinal, immunologic, endocrinologic (e.g. Cushing syndrome), pulmonary (other than either asthma not requiring continuous medication or sleep apnea-related disorders), or other disorders at the discretion of the investigators.
  • Recent use of colchicine or anorexiant medications in the last 3 months.
  • Known allergy to colchicine.
  • Previous history of agranulocytosis, gout, or significant myositis.
  • 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.
  • Individuals who have current substance abuse or a psychiatric disorder or any other condition that in the opinion of the investigators would impede competence, compliance, or participation in the study.
  • 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.
  • Use of anti-inflammatory medications (e.g. prednisone, NSAIDs) chronically or in the last 7 days prior to fat biopsy.
  • +41 more criteria
