Researchers are evaluating the topical drug clascoterone for pilonidal disease, a common, non-cancerous skin condition affecting the gluteal cleft. This randomized, double-blinded, placebo-controlled trial aims to determine whether clascoterone improves disease severity as assessed by physicians, reduces patient symptoms, and decreases inflammation seen under the microscope in tissue removed at surgery. Participants will be randomly assigned to apply either 1% clascoterone cream or a matching placebo cream twice daily to the affected area for 12 weeks. Assessments occur every 4 weeks, including medical photography of the diseased area, symptom surveys, and quality of life questionnaires. Those undergoing surgery within 4 weeks of treatment will have tissue samples analyzed for inflammation. Participants will attend visits at baseline and weeks 4, 8, and 12 for evaluations including physician assessments of disease severity through photos, the Dermatology Life Quality Index survey, and side effect monitoring. For those having surgery, wound healing and complications will be followed for 8 weeks post-operation. Tissue samples collected during surgery will be examined for immune cell presence and inflammation to compare effects between treatment groups.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | 1% clascoterone cream (twice daily) | Vehicle cream (twice daily) | Surgical excision with marsupialization |
|---|---|---|---|
| What it is | A twice‑daily topical application of 1% clascoterone cream applied to the natal cleft for 12 weeks. | A twice‑daily application of vehicle (non‑active) cream applied to the same area for 12 weeks. | Surgical removal of the pilonidal sinus followed by marsupialization closure, a common current practice for chronic disease. |
| Role in trial | Investigational active treatment arm. | Placebo‑control arm using vehicle cream. | Not part of the trial but represents usual surgical treatment outside the study. |
| Primary use | To reduce disease severity and improve quality of life via topical anti‑androgen therapy. | Serves as placebo to evaluate active treatment effect on disease severity and quality of life. | Definitive surgical management to remove disease and reduce recurrence. |
| How it is given or performed | Applied topically to the affected area twice daily for 12 weeks by the patient. | Applied topically to the same area twice daily for 12 weeks by the patient. | Performed surgically under anesthesia, with excision of sinus and marsupialization closure. |
| Evidence status | Effectiveness for pilonidal disease is currently under investigation; efficacy not yet established. | No therapeutic effect expected; serves as control for measuring active treatment effect. | Surgical excision with marsupialization has low recurrence rates and is considered effective for chronic disease. |
| Important risks | Safety profile in pilonidal disease is not yet established; known risks in other uses include local skin irritation. | Risks not fully known; cream base may cause local irritation. | Surgical risks include infection, wound complications, delayed healing, and recurrence. |
| Important limitations | Novel use with no prior evidence in pilonidal disease; unknown long‑term outcomes or recurrence impact. | Placebo control does not reflect active treatment and cannot inform on disease natural history. | Surgical management requires anesthesia, longer recovery, and may not be acceptable to all patients. |

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - 12 weeks
Participants apply 1% clascoterone cream or a matching vehicle cream to the affected area twice daily for 12 weeks. Participants attend assessment visits to have medical photography taken, complete a dermatology-specific quality of life questionnaire, and be assessed for any side effects.
4 visits at weeks 0, 4, 8, and 12
Duration - 8 weeks
Participants who undergo surgery within 4 weeks of treatment completion are followed for 8 weeks postoperatively to assess wound healing and complications through chart review.
