Health Condition(s) or Problem(s) studied

Erythropoietic Protoporphyria (EPP)
MedDRA version: 9.1 Level: LLT Classification code 10015289 Term: Erythropoietic protoporphyria

Intervention(s)

Product Name: CUV1647
Product Code: CUV1647
Pharmaceutical Form: Implant
Pharmaceutical form of the placebo: Implant
Route of administration of the placebo: Subcutaneous use

Primary Outcome(s)

Main Objective: -determine whether CUV1647 can reduce the number of phototoxic reactions in patients with EPP
-determine whether CUV1647 can reduce the severity of phototoxic reactions in patients with EPP

Primary end point(s): -The mean number of phototoxic reactions that occur whilst patients are on active compared with placebo implants. That is, the mean number of phototoxic reaction in (active) Group A between Days 0-60, 120-180, 240-300 plus Group B between Days 60-120, 180-240, 300-360 compared with (placebo) Group A between Days 60-120, 180-240, 300-360 plus Group B between Days 0-60, 120-180, 240-300

-The mean severity score for phototoxic reactions that occur whilst patients are on active compared with placebo implants. That is, the mean severity score in (active) Group A between Days 0-60, 120-180, 240-300 plus Group B between Days 60-120, 180-240, 300-360 compared with (placebo) Group A between Days 60-120, 180-240, 300-360 plus Group B between Days 0-60, 120-180, 240-300

Null Hypothesis: there is no difference between the mean number and severity of phototoxic reactions that occurred in patients treated with active and placebo.

Secondary Objective: -determine whether CUV1647 can increase the duration of sunlight tolerated by EPP patients
-determine whether CUV1647 increases melanin density in the skin at several specified body sites
-evaluate the safety and tolerability of CUV1647 by measuring treatment-emergent adverse events (AEs)
-determine whether CUV1647 can improve the quality of life of EPP patients
-in a subset of patients, determine whether CUV1647 implants can reduce the susceptibility to provocation with a standardized light source (time to appearance of provoked symptoms)
