pk study in subjects with renal impairment (severe and if required mild & moderate) compared to subjects with normal renal function

Conditions: Renal Impairment; Normal Renal Function

Summary: this is an open-label, non randomised, single-dose, study in male and female subjects with renal impairment (severe and if required mild \& moderate) compared to male and female subjects with normal renal function.


Eligibility criteria:
inclusion criteria: * a subject will be eligible for enrolment in the study if all of the following criteria apply: for groups 1, 2, 3 and 4 1. subject is able to provide written informed consent to participate in this study after reading the participant information sheet and informed consent form (icf) and after having the opportunity to discuss the study with the investigator or designee. 2. male or female subjects, ≥ 18 to 80 years of age (inclusive), at the time of signing the icf. 3. in the investigator's opinion, subject is able to understand the nature of the study and all risks involved with participation in the study and willing to cooperate and comply with all protocol restrictions and requirements. 4. subjects must weigh at least 50 kg (110 pounds) and have a body mass index 18 to 35 kg/m2 both inclusive at screening and on day -1. 5. the subject's vital signs must be within the reference range for their age at screening and on day 1. subjects must have rested for at least 5 minutes in a supine position prior to collecting blood pressure and pulse. in subjects with normal renal function, normal blood pressure is considered in the range of 90 to 145 mmhg for systolic blood pressure (sbp) and 50 to 95 mmhg for diastolic blood pressure (dbp). in subjects with renal impairment, normal blood pressure is considered in the range of 90 to 179 mmhg for sbp and 50 to 105 mmhg for dbp. pulse rate should be between 50 to 100 beats per minutes. 6. female subjects must not be lactating and must have a negative serum pregnancy test at screening and on day 1. 7. female subjects of child bearing potential and male subjects with a partner of child bearing potential must agree to use 2 effective methods of contraception (in female subjects, one method must be highly effective. for group 1 (subjects with normal renal function) 1. subjects must have an absolute egfr of ≥ 90 ml/min, as determined by the mdrd equation, multiplied by the individual bsa according to the dubois \& dubois equation and divided by 1.73 m2 at screening and confirmed at day 1 (admission to the study centre). 2. subjects must be in good health and free from clinically significant illness or disease in the opinion of the investigator based upon the results of medical history, physical examination, clinical laboratory tests (biochemistry, haematology, coagulation and urinalysis), vital signs and a 12 lead electrocardiogram (ecg) at screening and day -1. 3. subjects with normal renal function (group 1) will be matched in pairs by race, age (± 10 years of subject in group 4), weight (± 10 kg of the subject in group 4), gender and smoking status to subjects with severe renal impairment (group 4). for groups 2 to 4 (subjects with renal impairment) 1. subjects must have stable renal impairment based on medical history, physical examination and clinical laboratory results. stable renal impairment is defined as no clinically significant change in an egfr within 3 months or longer prior to study screening, as determined by the investigator. 2. subjects with renal impairment must have the following absolute egfr values as determined by the mdrd equation, multiplied by the individual bsa according to the dubois \& dubois equation and divided by 1.73 m2 at screening and confirmed at day 1 (admission to the study centre) group 2: mild renal impairment must have an absolute egfr of ≥ 60 to \< 90 ml/min group 3: moderate renal impairment must have an absolute egfr of ≥ 30 to \< 60 ml/min group 4: severe renal impairment must have an absolute egfr of \< 30 ml/min; not on dialysis 3. subjects must have acceptable clinical conditions in the opinion of the investigator based upon the results of medical history, physical examination, clinical laboratory tests (biochemistry, haematology, coagulation and urinalysis), vital signs and a 12 lead ecg at screening and day -1. 4. the age of subjects in groups 2 and 3 must not be more than 10 years younger than the youngest subject in group 1 or more than 10 years older than the oldest subject in group 1. the weight of subjects in groups 2 and 3 must not be more than 20% lighter than the lightest subject in group 1 or more than 20% heavier than the heaviest subject in group 1. 5. subjects with mild renal impairment (group 2) and moderate renal impairment (group 3) will be matched by race, age, weight and gender to subjects in group 1 (age and weight are to be matched as per inclusion criterion 4 above. it is not necessary to match subjects between groups 2 and 3 and group 1 in pairs, but there must be the same number of each gender and each race in each of groups 2 and 3 as there are in group 1). exclusion criteria: * a subject will not be eligible for this study if any of the following criteria apply: for groups 1, 2, 3 and 4 1. subjects who have a known clinically significant hypersensitivity to mt-7117 or related compounds (or relevant excipients). subjects who have a history of clinically significant hypersensitivity, intolerance, allergy or anaphylaxis to any drug compound, food or other substance unless approved by the investigator and the sponsor. 2. subjects who are currently on dialysis. 3. subjects who have any active malignancy (including melanoma but excluding basal cell carcinoma) or history of significant malignancy (including melanoma). 4. subjects who have previously participated in a study involving mt-7117 within 6 months prior to the first dose of investigational medicinal product (imp) and/or subjects who have previously taken any other investigational drug within 2 months or 5 half-lives prior to the first dose of imp, whichever is longer. 5. a history or presence of clinically significant neurological, haematological, psychiatric, gastrointestinal (including cholecystectomy), pulmonary or hepatic disease or other condition (with the exception of renal insufficiency for groups 2 to 4) known to interfere with the absorption, distribution, metabolism or excretion of drugs or any condition which could place the subjects at increased risk as determined by the investigator. 6. clinically significant 12-lead ecg abnormalities, including subjects with corrected qt interval using fridericia's formula (qtcf) of \> 450 ms (male) and \> 470 ms (female), at screening or day -1, confirmed by repeat assessment. 7. subject takes non-permitted concomitant medication within 28 days (or 5 half lives of the drug, whichever is longer) of dosing on day 1. subjects with normal renal function are restricted from use of any concomitant medications unless discussed and agreed with the sponsor. for renal impaired subjects, prescribed medication or over the counter (otc) medication for treating underlying disease states or chronic medical conditions or disorders related to renal impairment are permitted as described in the protocol. if subjects with renal impairment are on any medication not listed in the protocol, this must be discussed with the sponsor on a case-by-case basis, prior to the subject's inclusion in the study. 8. subjects who have a positive drug screen at screening or day 1 (admission to the study centre), unless the positive drug screen is due to prescription drug use that is approved by the investigator and the sponsor. 9. subjects who have a positive human immunodeficiency virus (hiv)
