E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of this study is to assess the efficacy of Skilarence® (Dimethyl Fumarate) at week 24 of treatment as measured by static Physician’s Global Assessment score (sPGA) multiplied by percentage Body Surface Area (BSA). |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to assess impact on:
o Dermatology Life Quality Index (DLQI)
o Psoriasis Area and Severity Index (PASI)
o Static Physician´s Global Assessment (sPGA)
o Body Surface Area (BSA)
o Patient satisfaction with Skilarence® treatment efficacy on psoriasis
in patients treated with Skilarence® (Dimethyl Fumarate) for 24 weeks, compared to baseline
• To describe the safety profile in moderate patients treated with Skilarence® (Dimethyl Fumarate) over 24 weeks
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
A research sub-study is appended to the final version of the main study protocol.
The aim of this research sub-study is to determine the molecular and cellular phenotype of moderate psoriasis patients in response to treatment with Skilarence®. |
|
E.3 | Principal inclusion criteria |
In order to participate in this study patients must meet all of the following inclusion criteria:
• Signed and dated informed consent
• Males and females ≥ 18 years
• Diagnosis of plaque psoriasis at least 6 months prior to screening visit
• BSA ≥ 5% at screening and baseline
• PASI score between 5 and 10 at screening and baseline
• Static Physician´s Global Assessment (sPGA) of 3 (moderate) based on a 6 point scale at screening and baseline
• DLQI ≥ 5 at screening and baseline
• Wash-out period for topical treatments (≥ 2 weeks) and for phototherapy and other non-biologic systemic therapies (≥4weeks) prior to baseline (Visit 2).
• A candidate to receive systemic treatment for psoriasis based on physician clinical judgement
• Women of child-bearing potential must have a negative serum pregnancy test at Visit 1 (Screening) and a negative urine pregnancy test at Visit 2 (Baseline)
• Females of child-bearing potential must be willing to use highly effective methods of birth control during the study period. Additionally they must agree to have pregnancy tests while on Skilarence®. Highly effective methods of birth control are defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly, such as implants, injectables, combined oral contraceptives, some Intrauterine Devices (IUDs), sexual abstinence or vasectomized partner. Female patients will be considered to be of childbearing potential unless surgically sterilized by hysterectomy or bilateral tubal ligation, or post-menopausal for 12 months or more.
• No previous use of biologic treatments for psoriasis or psoriatic arthropathy
|
|
E.4 | Principal exclusion criteria |
In order to participate in the study patients must not meet any of the following exclusion criteria:
• Females who are pregnant, breast feeding, refuse to use birth control methods or who wish to become pregnant during the study period
• Diagnosis of other psoriasis clinical subtypes such as guttate, erythrodermic or pustular psoriasis
• Diagnosis of active psoriatic arthropathy
• Diagnosis of Fanconi syndrome
• Baseline white blood cell count <3.0x109/L or lymphocyte count <1.0x109/L
• Previous malignancies (except for non-melanoma skin cancer)
• Severe impaired renal function: Severe renal impairment (creatinine clearance < 30 mL/min, estimated GFR using Modification of Diet in Renal Disease (MDRD) formula)
• Severe hepatic impairment (Child Pugh class C)
• Abnormal liver enzymes defined by:
• AST (SGOT), ALT (SGPT) and alkaline phosphatase (ALP) >3x the upper limit of the normal range (ULN) should be excluded. If bilirubin is >2x ULN, then an AST, ALT or ALP of >2x ULN is exclusionary. Elevated gamma-GT (GGT) values exceeding >3x ULN are allowed but these GGT cases will be carefully assessed alongside other clinical and laboratory data by the investigator
• History of severe gastrointestinal problems
• History of active infectious disease
• Known human immunodeficiency virus (HIV)-positive status or suffering from any other immunosuppressive disease
• Known to be hypersensitive to any of the ingredients of Skilarence®.
• Previously enrolled in any study or participating in any other drug investigational trial within the 30 days (or five half-lives of the investigational product studied, whichever is longer) prior to enrolment.
• History of major psychiatric illness
• Unable to comply with the requirements of the study or who in the opinion of the investigator should not participate in the study
