• −16\. History of any hypersensitivity to the active ingredient and/or excipients (lactose monohydrate, hydroxypropyl cellulose, carmellose calcium, magnesium stearate, hypromellose, titanium dioxide, talc, polyethylene glycol, iron oxide yellow, iron oxide red, and iron oxide black).
• −Additional screeningScreeningThe checks done before joining, to see whether a study fits.Read more → criteria check may apply for qualification:
• −A subject will NOT be eligible for this study if ANY of the following criteria apply:
• −1\. History or presence of photodermatoses other than EPP or XLP.
• −2\. Presence of clinically significant hepatobiliary disease at Screening, determined as clinically significant by the InvestigatorPrincipal investigatorThe doctor or researcher responsible for running the study at a site.Read more →.
• −3\. Subjects with AST, ALT, ALP ≥ 3.0 × upper limit of normal (ULN) or TB \> 1.5 × ULN at Screening. The TB level of \> 1.5 × ULN listed in this exclusion criteriaExclusion criteriaThe things that would prevent someone from taking part.Read more → may not be applicable to subjects with a documented medical history of Gilbert's syndrome. Please consult with the SponsorSponsorThe organisation responsible for the study overall.Read more → for eligibilityEligibility criteriaThe full list of requirements for taking part in a study.Read more → of subjects with elevated levels due to Gilbert's syndrome.
• −4\. Subjects with or having a history (in the last 2 years) of excessive alcohol intake in the opinion of the Investigator.
• −5\. History of melanoma.
• −6\. Presence of squamous cell carcinoma, basal cell carcinoma, or other malignant skin lesions. Any suspicious lesions or nevi will be evaluated. If the suspicious lesion or nevi cannot be resolved through biopsy or excision, the subject will be excluded from the study.
• −7\. History or presence of psychiatric disease judged to be clinically significant by the Investigator and which may interfere with the study evaluation and/or safety of the subjects.
• −8\. Presence of clinically significant acute or chronic renal disease based upon the subject's medical records including hemodialysis; an estimated glomerular filtration rate (eGFR) \<60 mL/min/1.73m2 as calculated by the CKD-EPI creatinine equation (2009) for adults and by the Schwartz creatinine equation for adolescents (2009). MDRD can be used for adults per local recommendations.
• −9\. Presence of any clinically significant disease or laboratory abnormality which, in the opinion of the Investigator, can interfere with the study objectives and/or safety of the subjects.
• −11\. Treatment with phototherapy or afamelanotide within 3 months before baselineBaselineYour starting measurements, taken before treatment begins.Read more → (Visit 2 or Re-entry Visit 2).
• −12\. Treatment with cimetidine or antioxidant agents at doses which, in the opinion of the Investigator, may affect study endpointsEndpointThe specific thing a study measures to answer its question.Read more → (including but not limited to beta-carotene, cysteine, pyridoxine) within 4 weeks before baseline (Visit 2 or Re-entry Visit 2).
• −13\. Chronic treatment with opioids, ketamine, or medical formulations or derivatives of cannabis within 4 weeks before baseline (Visit 2). Note: This exclusion criterion may not be applicable to subjects at Re-entry Visits. Acute use of scheduled analgesics more than 3 months before baseline (Visit 2) is allowed.
• −14\. Treatment with any drugs or supplements which, in the opinion of the Investigator, can interfere with the objectives of the study or safety of the subjects.
• −15\. Previous treatment with any investigational agent other than dersimelagon within 12 weeks before Screening OR 5 half-lives of the investigational product (whichever is longer).
• −18\. Using the following drugs (including but not limited to) within 1 week of baseline (Visit 2 or Re-entry Visit 2):
• −Drugs known to be predominantly metabolized by cytochrome P450 (CYP) 3A4 with a narrow therapeutic index for which elevated plasma concentrations are associated with clinical safety concern or significant medical events.
• −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.
• −10\. Female subjects who are pregnant, lactating, or intending to become pregnant during the study.
• −17\. Subjects who are unable to swallow tablets or have diseases significantly affecting the gastrointestinal function such as malabsorption syndrome, resection of the stomach or small bowel, bariatric surgery procedures, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction.
