About this trial

The goal of this clinical trial is to learn about the safety and efficacy of Pioglitazone in people with Pulmonary Hypertension (PH) due to Chronic Lung Disease (CLD). The main question it aims to answer is:

• Whether pioglitazone affects mitochondrial oxygen utilization in patients with PH due to CLD.

Participants will be asked to take pioglitazone or placebo once daily for 28 days followed by a washout period of 2 weeks followed by 28 days of the other study drug (participants randomized to placebo followed by pioglitazone or pioglitazone followed by placebo).

Trial outcomes

Primary outcomes

1

Change in Mitochondrial metabolism parameters: Spare respiratory capacity

Mitochondrial metabolism is measured using a research protocol employing the Agilent Seahorse extracellular flux bioanalyzer. Standard Seahorse assay protocols have been adapted for use with human platelets . Spare respiratory capacity (SRC) is calculated by (maximal respiration) - (basal respiration) during the mitochondrial stress test. The value is reported in pmol/min.

Time frame
Day 1, Day 28, Day 70
2

Change in Mitochondrial metabolism parameters: Maximal respiration

Maximal Respiration is calculated by: (post-carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone(FCCP) - (nonmitochondrial respiration) during the mitochondrial stress test. The value is reported in pmol/min.

Time frame
Day 1, Day 28, Day 70
3

Change in Mitochondrial metabolism parameters: Basal respiration

Basal respiration is calculated by (Baseline) - (nonmitochondrial respiration) ) during the mitochondrial stress test. The value is reported in pmol/min.

Time frame
Day 1, Day 28, Day 70

Secondary outcomes

1

Number of hypoglycemia incidences

Participants experiencing symptoms of hypoglycemia will be identified and reported.

Time frame
Day 1, Day 28, Day 70
2

Number of participants with leg edema

Participants reporting edema (\>2) will be captured.

Time frame
Day 1, Day 28, Day 70
3

Change in BNP levels

Change in Brain Natriuretic Peptide from the baseline will be calculated. Unit is pg/ml

Time frame
Day 1, Day 28, Day 70
4

Change in Six minute walk distance (6MWT)

The six-minute walk test (6MWT) is a standardized test of exercise capacity commonly used in patients with heart failure, lung disease, PH, and in pre-lung transplant evaluation. Results will be recorded as the distance walked in meters.

Time frame
Day 1, Day 28, Day 70
