E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether afamelanotide can reduce the severity of phototoxic reactions in patients with EPP. |
|
E.2.2 | Secondary objectives of the trial |
- To determine whether afamelanotide can reduce the number of phototoxic reactions in patients with EPP - To evaluate the safety and tolerability of afamelanotide by measuring treatment-emergent adverse events (AEs) - To determine whether afamelanotide can improve the quality of life of EPP patients - To determine the effect of afamelanotide on free protoporphyrin IX levels |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
To be eligible to enter the study, patients must meet the following inclusion criteria: - Male or female subjects with a positive diagnosis of EPP (confirmed by elevated free protoporphyrin in peripheral erythrocytes) - Aged 18-70 years (inclusive) - Provide written Informed Patient Consent prior to the performance of any study-specific procedure.
|
|
E.4 | Principal exclusion criteria |
To be eligible to enter the study, patients must not meet any of the following exclusion criteria: - Allergy to afamelanotide or the polymer contained in the implant or to lignocaine or other local anaesthetic to be used during the administration of the study medication - EPP patients with significant hepatic involvement - Personal history of melanoma or dysplastic nevus syndrome. - Current Bowen’s disease, basal cell carcinoma, squamous cell carcinoma, or other malignant or premalignant skin lesions. - Any other photodermatosis such as PLE, DLE or solar urticaria. - Any evidence of clinically significant organ dysfunction or any clinically significant deviation from normal in the clinical or laboratory determinations. - Acute history of drug or alcohol abuse (in the last 12 months). - Patient assessed as not suitable for the study in the opinion of the Investigator (e.g. noncompliance history, allergic to local anaesthetics, faints when given injections or giving blood). - Female who is pregnant (confirmed by positive serum β-HCG pregnancy test prior to baseline) or lactating. - Females of child-bearing potential (pre-menopausal, not surgically sterile) not using adequate contraceptive measures (i.e. oral contraceptives, diaphragm plus spermicide, intrauterine device). - Sexually active men with partners of child bearing potential not using barrier contraception during the trial and for a period of three months thereafter. - Participation in a clinical trial for an investigational agent within 30 days prior to the screening visit. - Prior and concomitant therapy with medications which may interfere with the objectives of the study, including drugs that cause photosensitivity or skin pigmentation.

E.5 End points |
E.5.1 | Primary end point(s) |
-Efficacy Endpoints: Efficacy will be assessed by: - Number and severity of phototoxic reactions - Quality of life measured with DLQI questionnaire and supplementary EPP specific questions - Free protoporphyrin IX in peripheral erythrocytes
Safety and Tolerability Endpoints: Treatment-emergent adverse events (coded as MedDRA Preferred Terms). Changes in hematology, serum chemistry and urinalysis measurements from Screening to Study Days 60, 120 and 180.
