NCT03060772

Brief Summary

This study is a single center, open-label, randomized clinical trial to determine the effect of pioglitazone (PIO) treatment on alveolar macrophage immune function, redox stress, and NADPH oxidase expression in outpatient alcoholic subjects. The researchers will recruit a cohort of otherwise healthy patients with an alcoholic use disorder from the Substance Abuse Treatment Program at the Atlanta Veterans Affairs (VA) Medical Center and randomize them to receive the usual treatment for two to four weeks or to the usual treatment plus PIO treatment for two to four weeks. There will also be a healthy control group (matched on age, gender, and smoking status) that will receive no treatment. To measure the effect of pioglitazone, participants will undergo a bronchoscopy before taking the study drug and then again 2-4 weeks later to look for changes. The bronchoscopy will allow researchers to obtain fluid from the lungs to see how well their immune cells respond to bacteria by determining phagocytic capacity.

Outcome Measures

Primary Outcomes (1)

  • Change in phagocytic index

    The change in phagocytic index will be determined between the alcohol use disorder study arms to examine the effect of PIO treatment. Phagocytic index of the alveolar macrophage is the rate at which particles are cleared from a culture. The phagocytic index is a well-established marker of immune function and its improvement with pioglitazone (PIO) treatment would indicate reversal of the alcoholic lung phenotype. The phagocytic index will be measured in bronchoalveolar lavage (BAL) fluids.

    Baseline, After 2-4 weeks

Secondary Outcomes (8)

  • Change in nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase)

    Baseline, After 2-4 weeks

  • Change in alveolar macrophage oxidative stress

    Baseline, After 2-4 weeks

  • Change in redox couple glutathione/glutathione disulfide (GSH/GSSG)

    Baseline, After 2-4 weeks

  • Change in cysteine/cystine (Cys/CySS) redox potential

    Baseline, After 2-4 weeks

  • Comparison of nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase)

    Baseline (control group), After 2-4 weeks (treatment group)

  • +3 more secondary outcomes

Study Arms (3)

Alcohol use disorder - Pioglitazone Treatment

EXPERIMENTAL

Participants with alcohol use disorder randomized to this group will receive pioglitazone. Study procedures include a bronchoscopy at baseline and an additional bronchoscopy after taking the study medication for 2 to 4 weeks.

Drug: Pioglitazone

Alcohol use disorder - No Pioglitazone

NO INTERVENTION

Participants with alcohol use disorder randomized to this group will receive their usual care but will not receive pioglitazone. Study procedures include a bronchoscopy at baseline and an additional bronchoscopy 2 to 4 weeks later.

Healthy controls without alcohol use disorder

NO INTERVENTION

Healthy individuals who do not have alcohol use disorder will be enrolled will serve as a control group. Healthy controls will be a matched to participants receiving the treatment based on age, gender, and smoking status. This group will have a single bronchoscopy.

Interventions

Participants will take 30 mg of pioglitazone once daily for a total of two to four weeks for those randomized to therapy, until the next bronchoscopy is performed. Participants will receive 14 to 28 tablets of active pioglitazone, which is enough to complete the minimum 14-day course of therapy.
