入选标准
- •1.Subjects provided written informed consent to participate. For minor subjects, both minor's assent and parental consent will be required.
- •2.Male and female subjects with a confirmed diagnosis of EPP or XLP based on medical history.
- •3.Subjects aged 12 years to 75 years, inclusive, at Screening.
- •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 willing to cooperate and comply with the protocol restrictions and requirements (including travel and receiving direct sunlight exposure as much as possible).
- •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 child-bearing potential currently using/willing to use 2 effective methods of contraception.
排除标准
- •1.History or presence of photodermatoses other than EPP or XLP.
- •2.Subjects who are unwilling or unable to go outside in sunlight during daylight hours most days (e.g., between 1-hour post-sunrise and 1 hour pre-sunset) during the study.
- •3.Presence or history of any hepatobiliary disease, including druginduced liver injury at screening, determined as clinically significant by the Investigator after the discussion with the Sponsor Medical Monitor.
- •4.Subjects with aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) >= 2.0 * upper limit of normal (ULN) or total bilirubin >1.5 * ULN at Screening.
- •5.History (in the last 2 years) or presence of alcohol abuse, or abuse of illicit drugs in the opinion of the Investigator.
- •6.History of melanoma.
- •7.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.
- •8.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.
- •9.Presence of clinically significant acute or chronic renal disease or subjects with an estimated glomerular filtration rate (eGFR) <60 mL/min as calculated by the Chronic Kidney DiseaseEpidemiology Collaboration (CKD-EPI) creatinine equation (2021) for adults and by the Schwartz creatinine equation for adolescents (2009). Modification of Diet in Renal Disease can be used for adults per local recommendations.
- •10.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.Female subjects who are pregnant, lactating, or intending to become pregnant during the study.
- •12.Treatment with any of the following medications or therapy within each period before Randomization (Visit 2);
- •Afamelanotide within 3 months
- •Phototherapy within 3 months
- •Cimetidine within 4 weeks
- •Antioxidant agents within 4 weeks, at doses which, in the opinion of the Investigator, may affect study endpoints (including but not limited to beta-carotene, cysteine, pyridoxine).
- •Chronic treatment with any scheduled analgesic agents including, but not limited to, opioids and opioid derivatives such as morphine, hydrocodone, oxycodone, fentanyl, or their combination with other unscheduled analgesics or non-steroidal anti-inflammatory drug (Percocet and Vicodin-like prescription drugs) within 4 weeks.
- •Note: Acute use of scheduled narcotics more than 3 months prior to randomization are allowed. Non-steroidal anti-inflammatory drug, aspirin for analgesia, or prior temporary use of scheduled agents within 3 months of screening is allowed.
- •13.Dermatological treatments 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 at screening, such as, for example, tanning agents.
- •14.Subjects who participated in any previous MT-7117 clinical studies.
- •15.Previous treatment with any investigational agent such as bitopertin, within 12 weeks before Screening or 5 half-lives of the investigational product (whichever is longer).
- •16.Use of sunscreens with zinc oxide.
- •Note: Sunscreens without zinc oxide are allowed, however their use, in frequency, quantity and body surface area should be maintained relatively stable throughout the duration of the study.
- •17.History of any hypersensitivity to the active ingredient and/or excipients (lactose monohydrate, hydroxypropylcellulose, carmellose calcium, magnesium stearate, hypromellose, titanium dioxide, talc, polyethylene glycol, iron oxide yellow, iron oxide red, and iron oxide black). (EU ONLY)
- •18.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. (EU ONLY)
- •19.History of any hypersensitivity to the active ingredient and/or excipients contained in MT-7117 IMP (lactose monohydrate, hydroxypropyl cellulose, carmellose calcium, magnesium stearate, hypromellose, titanium dioxide, talc, polyethylene glycol, iron oxide yellow, iron oxide red, and iron oxide black). (UK ONLY)
