Brief Summary:
15 patients with PRP will be treated with guselkumab for 20 weeks to determine safety and efficacy. Participants are required to travel to Portland, OR only for the first visit, week-4 visit, and week-24 visit. 3 visits in between these times and one follow up visit may be performed by secure videoconferencing.

Condition or disease Intervention/treatment Phase
Pityriasis Rubra Pilaris Biological: guselkumab Phase 2

Detailed Description:

Pityriasis rubra pilaris (PRP) is a rare and poorly understood severe inflammatory skin disease characterized by widespread (often full-body) redness and flaking of the skin, painful thickening and cracking of the palms and soles, hair loss, crumbling nails, and severe skin itching and burning.

There is no FDA-approved therapy for this rare disease and the commonly used medications do not work for many patients. There is some evidence that IL-23 may be too high in the skin of PRP patients. Ixekizumab is an injectable medication that blocks IL-23 by binding the p19 subunit and is FDA-approved for psoriasis.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label Pilot Trial of Guselkumab in the Treatment of Adults With Pityriasis Rubra Pilaris (PRP)
Actual Study Start Date : October 3, 2019
Estimated Primary Completion Date : July 2020
Estimated Study Completion Date : December 2020

Arm Intervention/treatment
Experimental: guselkumab treatment
Treatment with guselkumab for 20 weeks
Biological: guselkumab
Treatment at the FDA-approved psoriasis dosing for 20 weeks
Other Name: Tremfya

Primary Outcome Measures :
  1. Mean change from baseline PASI at week-24 after treatment with guselkumab. [ Time Frame: 24 weeks ]
    The Psoriasis Severity Index (PASI) is a well-validated tool for measuring psoriasis, based on redness, thickness, scale, and body surface area assessed by the investigator, with a maximum score of 72 points for the worst disease, and a score of 0 for clear skin. This is expected to be a useful tool for PRP, since PRP is characterized by widespread bright red erythema and scale, and is often initially misdiagnosed as severe psoriasis. The mean thickness score is expected to be lower in PRP than psoriasis but the mean body surface area (BSA) is expected to be higher than psoriasis.

Secondary Outcome Measures :
  1. Proportion of subjects achieving a 4-point improvement in quality of life measured by the Dermatology Life Quality Index (DLQI) at week-24. [ Time Frame: 24 weeks ]
    Quality of life will be measured by the Dermatology Life Quality Index (DLQI). There are 10 questions covering symptoms, embarrassment, shopping and home care, clothes, social and leisure, sport, work or study, close relationships, sex, and treatment. Each question refers to the impact of PRP on the patient's life over the previous week. The highest score is 30 and would indicate a maximum (negative) impact on quality of life. A score of zero would indicate no impact on quality of life. For inflammatory skin conditions, a 4-point change in DLQI score is considered clinically important.

  2. Proportion of subjects with sustained remission at week-36, 16 weeks after the last guselkumab dose, as measured by the mean change in PASI from week-24 to week-36. [ Time Frame: 36 weeks ]
    Subjects will be treated with guselkumab as per the FDA-approved psoriasis treatment guidelines, and therapy will be stopped after the 20-week dose. Subjects will be monitored at 24 weeks (primary study endpoint) and then at 36 weeks to assess for sustained remission versus relapse.
