Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
50mg dose
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.
Slow Release DHEA
DHEA is a hormone produced by the body's adrenal gland. In drug form, it is available as an over-the-counter supplement that is available on the market without prescription.
100mg dose
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.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Evidence of asthma demonstrated by reversibility at visit 0 or by historical methacholine or bronchodilator reversibility if testing was performed under either the 2017 ERS technical standard (22) or the 1999 ATS Guidelines (23) or outside studies, provided that full sets of flow volume loops have been reviewed and approved by the PI. These criteria are defined as one of the following:
* For bronchodilator reversibility: An increase in FEV1 ≥10% (24) compared to the baseline (and 200 ml) after up to 8 puffs of albuterol
* For historical methacholine responsiveness: Positive methacholine defined as PC20 ≤ 16 mg/ml, or PD20 ≤400 mcg
* Physician diagnosis of asthma according to NHLBI guidelines;
* Consistent use of an ICS/LABA inhaler for the prior 2 months;
* Non smoker;
* Females must not be pregnant or lactating;
* Absence of non-allergic comorbidities;
* Genotype testing positive for either HSD3B1 AA or AC specific variant
Exclusion Criteria
* positive urine pregnancy test
* Known lung disease other than asthma
* Acute (non asthma-related) dyspnea, viral respiratory illness or asthma exacerbation within 4 weeks of screening
* Systemic glucocorticoid dosing for maintenance \>10 mg/day of prednisone or equivalent
* Patients with significant non-allergic comorbidities (e.g. cerebral palsy, heart disease, kidney disease, liver disease, etc.)
* Patients with any know central or peripheral endocrine abnormality such as precocious puberty or diabetes
* Patients with any known previous adverse reaction to DHEA
* Current smoker or pack year history \> 5 years (includes vaping/nicotine inhalation devices)
* Positive urine cotinine test (\> 100 mg/mL)
* Use of prednisone or antibiotics in the last 4 weeks
* Use of any performance-enhancing drugs in the last 2 weeks
* Use of DHEA in the last 2 weeks
* Androgen use for any reason
* HSD3B1 CC phenotype
* Any other condition or finding that would compromise the safety of the subject or the quality of the study data, or otherwise interfere with achieving the study objectives, as determined by the PI
* Menopausal amenorrhea by history
* Positive PSA (\>4 ng/ml) (Prostate Specific Antigen)
* Prior diagnosis of vocal cord dysfunction, bronchopulmonary dysplasia, cystic fibrosis, chronic obstructive pulmonary disorder, or other lung disease
* Systolic blood pressure \> 150 mm Hg and/or diastolic blood pressure \>90 mm Hg
* Heart rates outside the range of 50 to 120 beats per minutes or with a pathologic irregularity
* Patients afflicted with any additional acute or chronic pathology that in the opinion of the screening physician makes them unsuitable for study or increases the risks associated with the study.
