4. Subjects are willing and able to travel to the study sites for all scheduled visits.
5. In the Investigator’s opinion, subject can understand the nature of the study and any risks involved in participation, and is willing to cooperate and comply with the protocol restrictions and requirements (including travel).
6. Female subjects who are non-lactating and have a negative urine pregnancy test at baseline visit prior to receiving the first dose of study drug.
7. Female subjects of childbearing potential and male subjects with partner of childbearing potential must agree to use 2 effective methods of contraception including barrier method (especially for female subjects, one method must be highly effective method) as described in Section 4.6.1.

E.4

Principal exclusion criteria

1. History or presence of photodermatoses other than EPP or XLP.
2. Presence or history of any hepatobiliary disease at screening determined as clinically significant by the Investigator after the discussion with the Sponsor Medical Monitor.

b. Drugs that are known substrates of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), organic anion transporting polypeptide (OATP)1B1, or OATP1B3 for which elevated plasma concentrations are associated with significant medical events.

E.5 End points

E.5.1

Primary end point(s)

1. Treatment-emergent adverse events (TEAEs) (including serious adverse events [SAEs] and adverse events of special interest [AESIs]).
2. Physical examination.
3. Vital signs (blood pressure, respiratory rate, pulse rate, and body temperature).
4. Clinical laboratory examinations (hematology, coagulation, biochemistry, and
urinalysis), including liver function markers (aspartate aminotransferase [AST], alanine aminotransferase [ALT], gamma glutamyl transpeptidase [GGT], alkaline phosphatase [ALP], direct and total bilirubin).
5. 12-lead electrocardiogram (ECG) parameters.
6. Nevi appearance (assessed by a dermatologist or other qualified site staff). Any nevi undergoing change of clinical concern during active treatment will be biopsied for follow up and evaluated by the central pathology lab.
