E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the therapeutic effect of alitretinoin (Toctino®) in the treatment of Cutaneous Lupus Erythematosus
with respect to proportion of responders based on the Revised Cutaneous Lupus Disease Area and Severity Index (RCLASI) activity score for skin lesions at baseline and after 24 weeks of treatment or at the latest assessment for patients who withdrew prematurely (Last Observation Carried Forward, LOCF). Response is defined as a reduction of 50% in the total RCLASI compared to the baseline value ("RCLASI 50") |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the proportion of responders after 12 weeks of treatment
• To evaluate the treatment effect of alitretinoin (Toctino®) with respect to change from baseline in the total
RCLASI activity score for skin lesions in comparison to week 12, and to the last day of treatment.
• Time from start of treatment to first response (time to response).
• To evaluate the proportion of failures of treatment after 12 and 24 weeks of treatment.
• To evaluate the Patient Assessment of Global Improvement (PAGI) score as well as subject’s assessment of
itching and pain assessed by a visual analogue scale (VAS) at baseline, as well as after 12 and 24 weeks of
treatment.
• To evaluate the safety and tolerability aspects of alitretinoin (Toctino®) in patients with CLE for the body as a
whole. |

of study treatment;
14. Initiation or change in the dose of any current systemic medication for the treatment of CLE/SLE prior to the
study (time depending on drug class and half-life);
15. Treatment with immunosuppressive drugs for other reasons, 4 weeks prior and within the study;
16. Concomitant treatment with drugs with a known photosensitizing potential, e.g. tetracyclines, griseofulvin,

E.5 End points |
E.5.1 | Primary end point(s) |
Primary efficacy outcome is the response rate at week 24 or at the latest assessment for patients who withdrew
prematurely (Last Observation Carried Forward, LOCF). Response is defined as a reduction of 50% in the total
RCLASI activity for skin lesions, compared to the baseline value ("RCLASI 50") |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The endpint will be evaluated after the last subject has completed the Study Completion Visit, any repeat
assessments associated with this visit have been documented and followed-up appropriately by the Investigator, and the database is closed. |
