Details and patient eligibility
About
The purpose of this study is to examine the use of a new investigational medication for the treatment of moderate plaque-type psoriasis. The study medication is rimegepant, an orally administered small molecule competitive inhibitor of the calcitonin gene-related peptide (CGRP) receptor. This medication, rimegepant, has been approved by the FDA under the trade name Nurtec for the treatment of acute migraine. However, rimegepant has not been studied in the treatment of moderate plaque-type psoriasis and is investigational for this indication.
Full description
This is a randomized, double-blind, placebo-controlled study of rimegepant 75 mg dosed every other day for the treatment of mild to moderate psoriasis. Subjects must have at 3% body surface area involvement before entry into the study. Psoriasis Area and Severity Index (PASI) and Investigator's Global Assessment (IGA) scores will be calculated and subjects will each complete the Dermatology Life Quality Index (DLQI) instrument as well an itch assessments. These assessments will be performed at baseline and every 2 weeks in follow-up. Areas of psoriasis in each subject will be photographed at baseline and two very similar appearing lesions identified for biopsy of one on day 1 and the other at the end of week 16. Patients will also repeat the DLQI at each visit. Subjects will also be photographed at each visit. Subjects will discontinue medications after the end of week 16. Subjects who complete the 20-week protocol will have the option of entering a 3-month, open-label extension of the study in which they will take 75 mg of rimegepant every other day for an additional 12 weeks. Eligible subjects have 2 weeks past visit 11 to enroll in the extension. For those rolling over before visit 11, visits 11 and 12 can be combined. They will have the same 7 assessments as in the previous portion of the study every 4 Protocol #20-07022368 Version Date 5/10/24 weeks including an EKG. The inclusion and exclusion criteria remain the same.

- One additional method. The other method could include hormonal contraceptives, or second barrier method as listed above.
-
The two options for men of childbearing potential should include:
- Simultaneous use of male condom, and for the female partner, hormonal contraceptives (for example, birth control pills, implants, patch, depot injection, used since at least 4 weeks) or intra-uterine contraceptive device (placed since at least 4 weeks) before sexual intercourse; OR simultaneous use of male condom, and for the female partner, diaphragm with intravaginally applied spermicide.
-

-
Inability for woman of child-bearing potential to use an effective form of contraception if sexually active.
-
Use of any medication that is a strong or moderate inhibitor of CYP3A, a strong or moderate inducer of CYP3A, or an inhibitor of glycoprotein (P-gp) or Breast Cancer Resistance Protein (BCRP). Please see Section 7.8 for more information.
-
Subject history with current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischemic heart disease, coronary artery vasospasm, and cerebral ischemia. Subjects with myocardial infarction (MI), acute coronary syndrome (ACS), percutaneous coronary intervention (PCI), cardiac surgery, stroke or transient ischemic attack (TIA) during 6 months (24 weeks) prior to screening.

-
Subjects with an active episode of major depressive episode within the last 6 months are ineligible. Subjects with major depressive disorder or any anxiety disorder are eligible only if they are on stable medication for each disorder for at least 3 months prior to the Screening visit.
-
Subject has a history or diagnosis of Gilbert's Syndrome or any other active hepatic or biliary disorder
-
Hematologic or solid malignancy diagnosis within 5 years prior to screening. Subjects with a history of localized basal cell or squamous cell skin cancer are eligible for the study if they are cancer-free prior to the screening visit in this study.

-
Subject has current diagnosis of major depressive disorder requiring treatment with atypical antipsychotics, schizophrenia, bipolar disorder, or borderline personality disorder.
-
The use of CGRP antagonists (biologic [e.g. Aimovig™, Emgality® and Ajovy™, VyeptiTM] or small molecule [ e.g. Ubrelvy™ {ubrogepant]]) other than rimegepant is prohibited during the study.
-
Concomitant use of atypical antipsychotics such as Abilify (aripiprazole), Zyprexa (olanzapine), Seroquel (quetiapine), Geodon (ziprasidone), or Risperdal (risperidone).
