E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the efficacy of oral liarozole, at a dose of 75 mg o.d. or 150 mg o.d. vs. placebo in the treatment of lamellar ichthyosis, measured by the average Investigator's Global Assessment at the end of 12 weeks of treatment. |
|
E.2.2 | Secondary objectives of the trial |
Include comparisons between liarozole and placebo on: · Overall Scaling Score · Severity scores of erythema and pruritus · Investigator’s Global Assessment at week 8 · Quality of Life (SF-36; DLQI/CDLQI) · Photographs · Safety and tolerability · Use of emollients and mechanical scale removal |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Subjects of either sex aged 18 years or older 2. Clinical diagnosis of lamellar ichthyosis with at visits 1 and 2 an Investigator’s Global Assessment of at least 3 when defined as follows: Investigator’s global assessment of the overall severity of subject’s lamellar ichthyosis at a particular time point, taking into consideration the two individual characteristics of ichthyosis (scaling and/or erythema), measured by the following 5-point Likert scale (0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe). 3. Women of childbearing potential are asked to use simultaneously 2 forms of effective contraception during the trial. The first one must be a hormonal contraceptive containing an association of progestin and estrogen and must be taken for at least 1 month (full cycle) before the start of treatment (visit 2). The second one must be a barrier method with spermicide and must be used at least from visit 1. Both forms must then be used during treatment and until one month after the end of the treatment period. 4. Women of childbearing potential should have a negative pregnancy test at screening visit (Visit 1), confirmed by another pregnancy test at Visit 2 before randomization. 5. Subjects are, except for their lamellar ichthyosis, in good general health and free of any disease state or physical condition that, in the investigator’s opinion, might impair evaluation of their lamellar ichthyosis. 6. Subjects signed informed consent. |
|
E.4 | Principal exclusion criteria |
1. Concurrent inflammatory skin disease unrelated to ichthyosis. 2. Subject is receiving topical (except emollient) or UV treatment for ichthyosis in the 2 weeks prior to the start of treatment (Visit 2). 3. Subject is receiving systemic therapy for ichthyosis in the 4 weeks prior to the start of treatment (Visit 2). 4. Subject is pregnant or breast feeding. 5. History or suspicion of alcohol or drug abuse. 6. Significant co-existing hepatic, renal, immune disease, chronic pancreatitis, osteoporosis or a history indicating adrenal cortex dysfunction. 7. Heart disorder requiring treatment, or a myocardial infarction within the previous 24 weeks or a history of heart-failure or clinically relevant cardiac arrhythmia. 8. Clinically significant abnormal electrocardiogram-intervals or morphology of the electrocardiogram; QT or QTc >470 ms in women or >450 ms in men. 9. History of hypersensitivity to retinoids. 10. History of hypersensitivity to any of the ingredients in the trial medication. 11. Clinically relevant laboratory abnormalities at screening, especially levels of blood triglycerides, cholesterol and liver function parameters. 12. Use of Vitamin A supplements in the 4 weeks prior to the start of treatment or during the trial. 13. Use of drugs metabolized by the CYP450 system at visit 2. 14. Use of immune-suppressive drugs including topical or systemic corticosteroids. 15. Participation in an investigational trial 30 days prior to the start of the trial (Visit 1). |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the percentage of responders to treatment. A subject is considered a responder if the Investigator's Global Assessment is decreased with at least 2 points on the 5-point Likert scale by the end of the treatment period. |
