doses of MT-3995 in subjects with Type II diabetic
nephropathy with albuminuria. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male and female subjects aged 18 to 75 years who have been diagnosed with Type 2 diabetes mellitus according to the criteria of the World Health Organisation (WHO) (WHO/NMH/CHP/CPM/11.1).
2. Subjects with a clinical diagnosis of diabetic nephropathy, who have been treated with ACE-I or ARB for a minimum of 12 weeks prior to screening and have been receiving a stable dose for at least 4 weeks prior to screening and remain on a stable dose up to baseline (Day 1 pre-dose).
3. Glycosylated haemoglobin (HbA1c) ≤10.5% at screening and Week -2.
4. An eGFR (MDRD formula20) ≥30 - <60 mL/min/1.73m2 at screening and Week -2. Due to variability, subjects with an eGFR of 27-29 or 60-62 mL/min/1.73m2 may be enrolled in the study at the discretion of the Investigator.
5. Albuminuria (UACR) ≥50 mg/g and ≤3500 mg/g (i.e., ≥5.66 mg/mmol and ≤395.85 mg/mmol) measured by median values of first-morning void urine samples on three consecutive days, both at screening and Week -2.
6. Subjects with a DBP <100 mmHg and an SBP <160 mmHg at screening.
7. Subjects with stable BP at Week -2 (compared with Week -4) and at baseline, Day 1 pre-dose (compared with Week -2). Stable BP is defined as a DBP within ± 10 mmHg from the previous BP measurement. Subjects must also have a DBP <110 mmHg and an SBP <180 mmHg at Week -4, Week -2 and baseline (Day 1 pre-dose).
8. Subjects who are on permitted medication must be on stable treatment for at least 4 weeks prior to screening and remain on a stable dose up to baseline as per Section 6.3.1 of Protocol.
9. Women may be enrolled if all of the following criteria (in addition to the other criteria) are met:
• they are not pregnant.
• they are not breast-feeding.
• they do not plan on becoming pregnant during the study.
10. Women of childbearing potential must agree to use two forms of effective contraception from the screening visit until at least 120 days after the last dosing day. Examples of effective contraception are: various types of hormonal contraception, barrier methods (male condom/cap/diaphragm with spermicide), and intrauterine devices. Women are considered to be of childbearing potential unless they meet one of the following criteria as documented by the Investigator:
• they have had a hysterectomy or bilateral tubal ligation prior to signing the Informed Consent Form (ICF); or
• they are post-menopausal, defined for women ≤50 years old as ≥2 years since their last menstrual period and for women >50 years old as ≥1 year since their last menstrual period.
If there are doubts as to the woman’s menopausal status, the levels of follicle stimulating hormone may be monitored. Women practicing abstinence or where the partner is sterile should be considered to be of childbearing potential.
11. Male participants in the study should use one of the following methods of contraception while having sexual intercourse with WOCBP from screening until at least 120 days after the last dosing day: total abstinence, condom (male or female) with spermicide.
12. Subjects who are capable of giving informed consent, complying with the restrictions and requirements of the protocol and, in the opinion of the Investigator, will be able to complete the study.

E.4 | Principal exclusion criteria |
1. History of Type I diabetes, pancreas or β-cell transplantation, or diabetes secondary to pancreatitis or pancreatectomy.
2. Central laboratory serum potassium level <3.5 or >5.2 mmol/L at screening, Week -2 or baseline (Day 1 pre-dose).
3. Local laboratory serum potassium level <3.5 or >5.2 mmol/L at baseline (Day 1 pre-dose).
4. Evidence of active urinary tract infection at screening.
5. Subjects who had acute kidney injury (AKI) within 3 months prior to baseline (Day 1 pre dose) or have undergone renal dialysis at any time prior to randomisation.
6. Subjects with a history of renal transplant.
7. Subjects diagnosed with non-diabetic kidney disease significantly impacting on albuminuria.
8. Subjects who are on both ARB and ACE-I.
9. Subjects with a persistent DBP <50 mmHg or an SBP <110 mmHg or symptomatic and clinically significant hypotension at screening, Week -4, Week -2 (i.e., 2 consecutive visits) or at baseline (Day 1 pre-dose).
10. Orthostatic hypotension defined as a >20 mmHg decrease in SBP and/or >10 mmHg decrease in DBP associated with clinical manifestations at screening.
11. ≥3 × upper limit of normal (ULN) aspartate aminotransferase (AST) or alanine aminotransferase (ALT) at screening or Week -2.
12. Clinically significant abnormalities of the thyroid (hypo- or hyperthyroidism measured by TSH, FT3 and FT4) at screening or Week -2, or subjects on thyroxine replacement therapy.
13. Subjects with evidence of acute ischaemia on 12-lead ECG at screening or baseline (Day 1 pre-dose).
14. Presence, history or known family history of long QT syndrome or Torsades de Pointes.
15. History of clinically significant multiple or severe drug allergies, allergy to MT-3995 or to any excipients (mannitol, carmellose calcium, light anhydrous silicic acid, talc and magnesium stearate) in the MT-3995 and matching placebo capsule.
16. Excessive consumption of food or drink containing high levels of potassium such as orange juice, melon and bananas, defined by local practice.
17. History of hospitalisation for hyperkalemia or AKI induced by previous RAAS blocker treatment.
18. Subjects who are taking any of the prohibited drugs, supplements or herbal remedies at screening or baseline (Day 1 pre-dose) (see Section 6.3.2). Any other medications will be allowed to continue unless in the opinion of the Sponsor and the Investigator, the medication will interfere with the objective of the study or compromise the subject’s safety.
19. Subjects who had general laser eye surgery 3 months prior to baseline (Day 1 pre-dose) or plan general laser eye surgery during the time the subject is expected to participate in the study.
20. Stroke, acute limb ischaemia, coronary and peripheral revascularisation procedure or myocardial infarction in the 6 months prior to baseline (Day 1 pre-dose).

Subjects who are suffering from any disease which, in the opinion of the Investigator, is sufficiently severe to render the subject unfit, or affect the subject’s ability to participate in the study. Subjects with evidence of any malignancy within the last 5 years prior to screening, with the exception of history of basal cell skin cancer.
24. Subjects who participated in a clinical study of any IMP (other than placebo) within 12 weeks (from last administration) prior to baseline (Day 1 pre-dose) or who are currently participating in another clinical study.
