Treatment of Moderate Hidradenitis Suppurativa

• Status: Unknown status
• Trial end date: 2020-05-01
• Target enrollment: 0
• Participant gender: All

Summary

The study will be conducted over 24 weeks on active therapy followed by a four-week observational visit. The total length of the study will be 28 weeks.

Study visits will occur at Screening, Baseline (Week 0), Weeks 4, 8, 12, 16, 20, 24 followed by an observational visit. Additionally, all subjects will be contacted by phone 1 week following the Baseline visit to ensure daily pain assessments are being recorded. If any signs or symptoms are reported at the time of the call, an unscheduled study visit will be conducted to assess whether an infection is present.

Adverse events will be collected throughout the study.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:Subjects are included in the study if they meet all of the following criteria:

• Male or female, at least 18 years of age..

• Subject must be in general good health ( except for Hidradenitis Suppurativa) as judged by the Investigator, based on medical history, physical examination, clinical laboratories and urinalysis. NOTE: the definition of good health means a subjects that does not have uncontrolled significant co-morbid conditions.

• HS lesions must be present in at least two distinct anatomic areas, one of which must be at least Hurley Stage II (see definition of terms)

• Subject must have stable HS for at least 2 months (60 days) prior to Screening/ Baseline visit as determined by the investigator through subject interview and review of medical history;

• Subject must have a total abscess and inflammatory nodule (AN) count (PGA) of no greater than moderate at the Baseline visit. Patient with PGA 0-1 (No disease or minimal Disease will be excluded).

• Subject must agree to daily use (and throughout the entirety of the study) of one of the following over-the-counter topical antiseptics on their HS lesions: chlorhexidine gluconate, triclosan, benzoyl peroxide, or dilute bleach in bathwater.

• Women who are postmenopausal must have a negative serum pregnancy test on entry in the study.

• Females of childbearing potential (FCBP)† must have a negative pregnancy test at Screening and Baseline. While on investigational product and for at least 28 days after taking the last dose of investigational product, FCBP who engage in activity in which conception is possible must use one of the approved contraceptive§ options described below:

Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner's vasectomy; OR Option 2: Male or female condom (latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]; PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.

Male subjects (including those who have had a vasectomy) who engage in activity in which conception is possible must use barrier contraception (male latex condom or nonlatex condom NOT made out of natural [animal] membrane [for example, polyurethane]) while on investigational product and for at least 28 days after the last dose of investigational product.

A female of childbearing potential is a sexually mature female who 1) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for at least 24 consecutive months (that is, has had menses at any time during the preceding 24 consecutive months).

The female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal contraception should be initiated at least 28 days before randomization).

• The screening/baseline laboratory test results must meet the following criteria (WNL means within normal limits for patients with HS [e.g., may have slightly higher WBC and platelet counts]):

• WBC (white blood cell count): WNL

• ANC (absolute neutrophil count): WNL

• Hemoglobin: >10 mg/dl
