Brodalumab in Palmoplantar Psoriasis
Study Details
Study Description
Brief Summary
This is a Phase 4 single center, single-arm, open-label study that will evaluate the efficacy and safety of brodalumab in psoriasis patients as well as the impact on quality of life in addition to clinical photography. Efficacy will be evaluated by a study treatment assessor. The study includes a 30-day screening period with study visits at Week 0, 2, 4, 8, 12, 16, and 24. Study drug dosing will consist of patients self-injecting according to on-label FDA approved dosing of brodalumab 210mg at week 0, 1, 2 and then every 2 weeks thereafter for moderate to severe psoriasis patients after adequate injection training is given at study center site. Subjects will be instructed at Week 0 (pre-injection) by the site staff on how to self-inject via the dosing syringe. Study drug will be dispensed through the delineated REMS approved pharmacy. Baseline assessment will be performed at week 0 and efficacy assessments will be performed at week 4, 8, 12, 16 and 24, then every 2 weeks thereafter for palmoplantar psoriasis using approved dosing schedule for moderate to severe psoriasis. Patients will self inject after adequate injection training is given at the study center site.

Outcome Measures

Eligibility Criteria
Criteria
Inclusion Criteria:
Consent
- Subjects or their legally authorized representative must voluntarily sign and date an informed consent, approved by an independent ethics committee (IEC)/institutional review board (IRB), prior to the initiation of any screening or study-specific procedures.
Demographic and Laboratory Assessments
-
Adult male or female, at least 18 years old.
-
Laboratory values meeting the following criteria prior to the first dose of study drug: Serum aspartate transaminase < 3 × upper limit of normal (ULN); Serum alanine transaminase 3 2 × ULN; Serum direct bilirubin ≤ 2.0 mg/dL; except for subjects with isolated elevation of indirect bilirubin relating to a confirmed diagnosis of Gilbert syndrome; Total white blood cell count > 3,000/µL; Absolute neutrophil count > 1,500/µL; Platelet count > 100,000/µL; Hemoglobin > 8 g/dL. (Note: If an exclusionary laboratory result is obtained during the Screening period, one re-test of that particular test is allowed without repeating all other laboratory tests within the 30 day screening window. If the patient has recent laboratory examinations within 3 months, these results can be taken in lieu of screening labs. Subjects who initially do not meet all eligibility criteria for the study may be permitted to repeat the Screening Visit one time following re-consent. )

Contraception Requirements for Females Subjects must follow the following contraceptive guidelines as specified: Females, Non-Childbearing Potential Females do not need to use birth control during or following study drug treatment if considered of non-childbearing potential due to meeting any of the following criteria:
-
Postmenopausal, age > 55 years with no menses for 12 or more months without an alternative medical cause
-
Postmenopausal, age ≤ 55 years with no menses for 12 or more months without an alternative medical cause AND a follicule-stimulating hormone (FSH) level > 40 IU/L
-
Permanently surgically sterile (bilateral oophorectomy, bilateral salpingectomy, or hysterectomy)
-
Females who have not experienced menarche (at least one menstrual period)
-
Females of Childbearing Potential
-
Females of childbearing potential must avoid pregnancy while taking study drug(s) and for at least 70 days after the last dose of study drug. Females must commit to one of the following methods of birth control:
-
Combined (estrogen and progestogen containing) hormonal birth control (oral, intravaginal, transdermal, injectable) associated with inhibition of ovulation initiated at least 1 month prior to study Baseline (Study Day 1)
-
Progestogen-only hormonal birth control (oral, injectable, implantable) associated with inhibition of ovulation initiated at least 1 month prior to study Baseline (Study Day 1)
-
Bilateral tubal occlusion/ligation (can be via hysteroscopy, provided a hysterosalpingogram confirms success of the procedure)
-
Intrauterine device (IUD)
-
Intrauterine hormone-releasing system (IUS)
-
