Comparative Effectiveness Study of Spironolactone Versus Doxycycline for Acne
Study Details
Study Description
Brief Summary
Acne is common illness of adolescents and young adults which is associated with substantial morbidity. While topical treatments are often sufficient for mild acne, moderate to severe acne often requires treatment with systemic medications such as oral antibiotics, hormonal therapies such spironolactone, and isotretinoin. Sebum overproduction is fundamental to the pathogenesis of acne with associated disordered keratinization and subsequent microbial colonization and inflammation resulting in the clinical manifestations of acne. Given the influence of hormones on sebum production, therapies that address these underlying hormonal factors such as spironolactone and oral contraceptive pills represent an underutilized treatment option for women with acne and could help decrease the use of long-term oral antibiotics in this patient population. The purpose of this trial is to evaluate the comparative effectiveness of spironolactone versus doxycycline hyclate (tetracycline class antibiotic) for women with acne.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Spironolactone In this arm, participants will receive spironolactone 100mg/day for the entirety of the study. To maximize the generalizability of the study, participants will be allowed to continue their current topical regimen as long as no changes were made in the 4 weeks prior to randomization. No additions to their topical regimen may be made during the study period. |
Drug: Spironolactone
Dispensation of spironolactone according to the arm description.
|
Active Comparator: Doxycycline hyclate This arm is an active-comparator arm in which participants will receive doxycycline hyclate 100mg/day for the entirety of the study. To maximize the generalizability of the study, participants will be allowed to continue their current topical regimen as long as no changes were made in the 4 weeks prior to randomization. No additions to their topical regimen may be made during the study period. |
Drug: Doxycycline Hyclate
Dispensation of doxycycline hyclate according to the arm description.

Outcome Measures
Primary Outcome Measures
- Absolute change in inflammatory papules and pustules [Baseline to Week 16]
Difference in change in inflammatory papules and pustules between those randomized to spironolactone versus doxycycline hyclate
Secondary Outcome Measures
- Percentage achieving Investigator Global Assessment (IGA) Success (IGA grade of clear or almost clear; grade 0 or 1) [Baseline to Week 8, and Week 16]
Difference in percentage achieving IGA success between those randomized to spironolactone versus doxycycline hyclate
- Change in comedonal lesions [Baseline to Week 8, and Week 16]
Difference in change in comedonal lesions between those randomized to spironolactone versus doxycycline hyclate
- Change in Acne-QoL, an acne-specific quality of life measure [Baseline to Week4, Week 8, Week 12, and Week 16]
Difference in change in Acne-QoL score between those randomized to spironolactone versus doxycycline hyclate. There are 4 subscales: self perception, scored 0-30; role social, scored 0-24; role-emotional, scored 0-30; and acne symptoms, scored 0-30. Higher scores indicate better quality of life.
- Change in Dermatology Life Quality Index (DLQI), a dermatology-specific quality of life measure [Baseline to Week4, Week 8, Week 12, and Week 16]
Difference in change in DLQI score between those randomized to spironolactone versus doxycycline hyclate. Scores range from 0-30, with lower scores indicated better quality of life.
- Patient global assessment [Baseline to Week4, Week 8, Week 12, and Week 16]
Difference in change in patient global assessment scores between those randomized to spironolactone versus doxycycline hyclate.
- Percentage on any topical medication at baseline who discontinued at least one of these topical medications (i.e. topical retinoid, benzoyl peroxide, and topical antibiotic) [Baseline to Week 16]
Difference between those randomized to spironolactone versus doxycycline hyclate
