Trial Summary

What is the purpose of this trial?

This trial is studying how a slow-release form of DHEA behaves in people with severe asthma who have certain genetic markers. The goal is to see if these patients process the hormone differently, which could affect how it should be dosed.

Do I have to stop taking my current medications for the trial?

The trial does not specify if you need to stop taking your current medications, but you must have been using an ICS/LABA inhaler consistently for the past 2 months. You cannot have used prednisone, antibiotics, performance-enhancing drugs, or DHEA in the last few weeks.

What data supports the idea that Slow Release DHEA for Asthma is an effective treatment?

The available research shows that Slow Release DHEA, specifically in the form of DHEAS delivered via a nebulizer, can improve asthma control in patients with moderate-to-severe asthma. In a study, patients who received DHEAS showed a significant improvement in their asthma control scores compared to those who received a placebo. Specifically, 59.4% of patients in the DHEAS group experienced a noticeable improvement in their symptoms, compared to 45.7% in the placebo group. This suggests that DHEAS can be an effective treatment for improving asthma symptoms. ^{1 2 3 4 5}

What safety data is available for Slow Release DHEA in asthma treatment?

The safety data for Slow Release DHEA, also known as dehydroepiandrosterone (DHEA), in asthma treatment is limited but promising. Studies suggest that DHEA has immunomodulating and anti-inflammatory properties that could benefit asthma patients without the side effects of glucocorticoids. A study on nebulized DHEA-3-sulfate (DHEAS) showed improved asthma control with few adverse events and no changes in sex hormones. Another study indicated that DHEA could reduce allergic airway inflammation in mice. Additionally, DHEA has been used in adrenocortical insufficiency with moderate and acceptable androgenic side effects. Overall, while more research is needed, existing studies suggest a favorable safety profile for DHEA in asthma treatment. ^{1 2 3 4 6}

Is the drug Slow Release DHEA a promising treatment for asthma?

Yes, Slow Release DHEA shows promise as a treatment for asthma. It can help reduce inflammation and improve asthma control, potentially offering benefits without the side effects of other asthma medications. ^{1 2 4 5 7}

Treatment Details

Interventions

• Slow Release DHEA (Hormone Therapy)

Trial Overview The trial is testing how different doses of slow release DHEA are processed in the body (pharmacokinetics) in subjects with severe asthma. The goal is to understand how this treatment affects individuals with specific genotypes.

Participant Groups

Group I: 50mg dose Experimental Treatment 1 Intervention

This arm will start with a one-time dose and progress to twice daily dosing for 3 days, every 12 hours. Study cohort will be 9 subjects with asthma. DHEA dose will be 50 mg via slow release capsules. Endpoints will be serum DHEA and DHEA-S levels at 10, 20, 30, 60 min \& 2, 4, 6, 8, 12h after administration. After a one-week washout period, the protocol will be repeated using 100 mg of SR-DHEA.

Group II: 100mg dose Experimental Treatment 1 Intervention

This arm will start with a one-time 100mg dose and progress to twice daily dosing for 3 days, every 12 hours. Study cohort will be same 9 subjects with asthma. DHEA dose will be 100mg via slow release capsules. Endpoints will be serum DHEA and DHEA-S levels at 10, 20, 30, 60 min \& 2, 4, 6, 8, 12h after administration.

Findings from Research

DHEA has the potential to improve asthma treatment by reversing cytokine imbalances and reducing allergic inflammation in the airways, making it a promising alternative to traditional glucocorticoids.

Unlike glucocorticoids, DHEA does not have undesirable side effects and may help patients who are resistant to corticosteroids, offering a steroid-sparing effect for those on high doses of glucocorticoids.

Inhaled dehydroepiandrosterone-3-sulfate (DHEAS) significantly improved asthma control in patients with moderate-to-severe asthma, as evidenced by a notable reduction in Asthma Control Questionnaire (ACQ) scores after 6 weeks of treatment.

The safety profile of inhaled DHEAS was favorable, with fewer respiratory-related withdrawals and minimal adverse events, indicating it may be a safe addition to asthma management without affecting sex hormone levels.

Prasterone (DHEA) replacement therapy at a daily dose of 50 mg effectively raises plasma DHEAS levels to normal, showing beneficial effects on mood, fatigue, general well-being, and sexual function in patients with adrenocortical insufficiency.

The treatment appears to have moderate and acceptable androgenic side effects on skin and hair, making it a justifiable option for patients who do not fully respond to standard glucocorticosteroid therapy.

In a study of 108 patients with bronchial asthma, men had significantly higher levels of the adrenal androgen dehydroepiandrosterone sulfate (DHEAS) compared to women, which may influence asthma severity.

Lower serum DHEAS levels were associated with reduced forced expiratory volume in 1 second (FEV1), indicating that patients with severe asthma and low DHEAS may experience more frequent and prolonged asthma attacks, and show limited improvement in lung function with bronchodilator therapy.
