Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot start new PAH therapy or change the dose significantly within 12 weeks before the trial. Also, you cannot use hormone supplements or certain hormonal therapies.

What evidence supports the effectiveness of the drug DHEA for treating pulmonary hypertension?

Research shows that DHEA can improve heart function and reduce stress on the heart in animal models of pulmonary hypertension, and it has been shown to help with similar conditions in humans, like those related to chronic obstructive pulmonary disease (COPD).12345

Is DHEA safe for humans?

DHEA, a hormone, has been studied in various trials and is generally well tolerated by humans, with ongoing research to assess its safety and effects in conditions like pulmonary hypertension.12346

How does the drug DHEA differ from other treatments for pulmonary hypertension?

DHEA is unique because it directly targets the heart's right ventricle function and influences nitric oxide and endothelin-1 signaling, which are not directly addressed by other treatments. It also acts as an activator of calcium-gated potassium channels, which helps reduce pulmonary hypertension by affecting blood vessel function.12346

What is the purpose of this trial?

The goal of this crossover trial is to determine whether the study drug dehydroepiandrosterone (DHEA) improves right ventricular longitudinal strain measured by cardiac magnetic resonance imaging at 18 weeks compared to placebo and to assess side effects and safety in pulmonary arterial hypertension.

Eligibility Criteria

This trial is for adults with pulmonary arterial hypertension, a type of high blood pressure affecting the lungs. Participants must have specific heart and lung function test results and can't be pregnant or breastfeeding, have certain cancers, severe kidney or liver disease, untreated thyroid issues, or use hormone therapies.

Inclusion Criteria

You have high blood pressure in the arteries of your lungs and high resistance in the blood vessels of your lungs.
I have been diagnosed with PAH due to genetics, a heart defect, or other specific causes.
My lung scans show moderate or less lung damage and I meet specific lung function criteria.

Interventions

  • DHEA
  • Placebo
Trial Overview The study tests if DHEA tablets improve heart muscle function in the right ventricle compared to placebo over 18 weeks. It's a crossover trial where participants will receive both the DHEA treatment and placebo at different times to compare effects.
