Acne vulgaris of adult woman has increased over the past 10 years; it affects currently 20% to 30% of adult women.
The physiopathology of adult woman acne is distinguished from the teenager one by essentially 2 factors:
- hormonal factor with a peripheral hyperandrogenism coupled with an hypersensibility of cutaneous androgens receptors of these women. But this point is still at the stage of hypothesis.
- inflammatory factor linked with Propionibacterium Aces ; indeed these women received most of the time many cures of local and systematic antibiotics at the origin of resistant Propionibacterium Aces strains which lead to a chronical activation of cutaneous innate immunity.
On a therapeutic plan, four types of systemic treatment, approved in this indication are:
- Tetracyclines which are problematic for the bacterial resistance and consequently constant relapse when they are stopped.
- Zinc salts which target only the inflammatory lesions and were shown less effective than cycline
- Antiandrogens, with acetate of cyproterone associated with risks of phlebitis and pulmonary embolism, and increase risk of triglycerides, cholesterol and hepatic balance.
- The last alternative is represented by isotretinoin but the use in women of childbearing potential is binding because of the teratogen risks and the hyperandrogenism represents an identified risk of relapse.
In this context, the spironolactone could represent an interesting alternative. It blocks the 5-alpha-reductase receptors at sebaceous gland and inhibits Luteinizing hormone (LH) production at the pituitary level. It is not submitted to isotretinoin constraints, does not lead to bacterial resistance and targets the peripheral hyperandrogenism.
Currently, very few studies have been performed and on a weak number of patients but they showed that at low doses (lower than 200mg/day), spironolactone can be effective against acne.
In that context, it seemed clearly interesting to perform the first double-blind randomized study spironolactone vs cyclines which remains the moderate acne reference treatment and to demonstrate the superiority of spironolactone's efficacy in order to establish it as alternative way to cycline.

|Estimated Study Completion Date :||June 30, 2023|
Spironolactone ARROW ® 75 mg, 150mg, orally, once a day during all the trial (12 months: 6 months on double-blinded spironolactone then 6 months on open-label spironolactone), + topical therapy during all the trial (benzoyl peroxide 5%)
Dispensation of spironolactone at each visit according to the arm description described above.
Active Comparator: doxycycline
(Doxycycline Sandoz 100 mg), 100mg/day during 3 months followed by placebo during 3 months, on double-blinded + topical therapy during all the trial (benzoyl peroxide 5%
Dispensation of doxycycline then placebo, at each visit according to the arm description described above.
- Treatment efficacy [ Time Frame: Month 4 and Month 6 ]
The treatment's efficacy will be determined by the rate of success in each arm. The best rate of success between Month 4 and Month 6 will be chosen for the final result. Rate of success, defined by a decrease of both Adult Female Acne Scoring Tool (AFAST) scores 1 and 2:
- AFAST score 1: decrease of at least 2 grades compared to baseline or to grade 0 if the baseline was at 1 and
- AFAST score 2: decrease to grade 1 if baseline was > 1 or to grade 0 if the baseline was at 1
AFAST 1 (also called GEA) assesses the comedones (open and closed), the non-inflammatory lesions, the papules and pustules and the nodules. The stage is defined according to a global evaluation of severity of acne and ranges from Grade 0 (no acne) to Grade 5 (the worse situation).
AFAST 2 assesses acne on an area from the left and right mandibular zone to the upper edge of the trunk and ranges from Grade 0 (no acne) to Grade 3 (the worse situation).
- Clinical adverse events [ Time Frame: Within 12 months after randomization ]Number and type of Adverse Events (AE) and Serious Adverse Events (SAE) occurring from the beginning of the treatment until end of the follow-up
- Sodium abnormal values (biological adverse events) [ Time Frame: From 30 days to 7 days before randomization visit, Month 2, Month 4, Month 9 ]Sodium measurement (mmol/L)
- Potassium abnormal values (biological adverse events) [ Time Frame: From 30 days to 7 days before randomization visit, Month 2, Month 4, Month 9 ]potassium measurement (mmol/L)
- Chlore abnormal values (biological adverse events) [ Time Frame: From 30 days to 7 days before randomization visit, Month 2, Month 4, Month 9 ]Chlore measurement (mmol/L)
- Calcium abnormal values (biological adverse events) [ Time Frame: From 30 days to 7 days before randomization visit, Month 2, Month 4, Month 9 ]Calcium measurement (mmol/L)
- AFAST score 1 (GEA) at 0 or 1 [ Time Frame: Month 2, Month 4, Month 6, Month 9 and Month 12 ]Number of patients with AFAST score 1 (GEA) at 0 or 1.

- Quality of life (cost-utility assessment and general quality of life assessment) [ Time Frame: Month 2, Month 4, Month 6, Month 9 and Month 12 ]EQ-5D (EuroQol 5 dimensions) questionnaire: The questionnaire focuses on five dimensions: mobility, personal autonomy, current activities, pain/discomfort, and anxiety/depression. For each of these dimensions, three answers are possible.

- Trunk lesions [ Time Frame: Day 0 (baseline), Month 2, Month 4, Month 6, Month 9 and Month 12 ]Factor F2 of ECLA scale ECLA ("Echelle de Cotation des Lésions d'Acné") is a scale for acne proposed by the dermatology research team of Nantes University Hospital. It is composed of 3 factors: Factor 1 (F1) counts the acne lesions on the face; Factor 2 (F2) counts the lesions acne on the trunk and Factor 3 (F3) counts the scars. In this study, the factor F2 will be used. The factor F2 assesses the extensive character of acne lesions on 5 defined areas: cervical areas (F2N); chest areas (F2C); back area (F2B) and arm area (F2A) according to a qualitative scale 0=absent, 1=poor 2=medium 3=significant. It is completed by the count of the present nodules in each area.

- Reappearance of 10% and more of inflammatory lesions. [ Time Frame: Month 6 ]Number of patients with a reappearance of 10% and more of inflammatory lesions.
- Incremental cost-effectiveness ratio (cost per Quality-Adjusted Life-Year, QALY) of the comparison between the spironolactone and cycline. [ Time Frame: Month 6 ]costs: resources consumed, QALY: EQ-5D
