This is an interventional treatment trial for Diabetic Nephropathy focused on measuring Drug therapy Read More

Inclusion Criteria:

1. In the opinion of the investigator, the participant is capable of giving informed consent to enter the trial, including understanding and complying with protocol requirements.
2. The participant or, when applicable, (eg, where the subject is capable of giving verbal informed consent to enter the trial but cannot physically sign a written, informed consent form), the participant's legally acceptable representative signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
3. At the time of Screening the participant is male or female and aged 18-90 years inclusive at first dose of study medication.
4. Was previously diagnosed with type 2 diabetes mellitus per American Diabetes Association criteria.
5. Has an estimated glomerular filtration rate (eGFR) based on serum creatinine (eGFR, determined by Modification of Diet in Renal Disease [MDRD] equation) of 25-59 mL/min/1.73 m(2) at Screening.
6. Has been on a stable dose of angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB) for 8 weeks prior to Screening.
7. Has residual albuminuria despite stable treatment with an ACE inhibitor or an ARB for at least 8 weeks prior to Screening (albumin:creatinine ratio [ACR] of > 300 mg/g creatinine, inclusive at Screening).
8. Has glycosylated hemoglobin (HbA1c) less than or equal to 10.5% at screening.
9. If a subject is regularly using dipeptidyl peptidase-4 inhibitor (DPP-4i) or sodium-glucose cotransporter 2 inhibitor (SGLT2i) to treat diabetes, he/she has been on a stable dose and regimen within 2 months prior to Screening.
10. All participants who are not surgically sterile or post-menopausal, or whose partners are not surgically-sterile or postmenopausal, must use two effective birth control methods or abstain from intercourse during this study.

Exclusion Criteria:

1. Has received any investigational compound within 90 days prior to Screening.
2. Is an immediate family member, study site employee, or is in a dependant relationship with a study site employee who is involved in the conduct of this study (eg, spouse, parent, child, sibling) or may consent under duress.
3. Is taking any combination of dual renin-angiotensin system (RAS) inhibition (such as an ACE inhibitor and an ARB or an ACE inhibitor and a mineralocorticoid receptor antagonist).
4. Has type 1 diabetes mellitus or a history of ketoacidosis.
5. Has poorly-controlled blood pressure (systolic blood pressure >160 or diastolic blood pressure >110, with blood pressure measured in the seated position after at least 5 minutes of rest) at Screening and Day 1.
6. Has received dialysis within 3 months of Screening.
7. Has infectious diseases or leg ulcers at Screening (all per discretion of Principal Investigator [PI]).
8. Has severe concurrent disease which, in the judgment of the investigator, would interfere significantly with the assessments of safety and efficacy during this study.
9. Has known infection with human immunodeficiency virus (HIV), or a positive test for Hepatitis B, Hepatitis C, or tuberculosis (TB) at Screening. Subjects who have a positive TB skin test at Screening must rule out active or latent tuberculosis documented by chest x-ray in order to be considered eligible for study participation.
10. Has used long-term immune suppressants, steroid therapy (except for topical use or inhalation), chronic use of non-steroidal anti-inflammatory drug (NSAIDs), cyclooxygenase type 2 (COX-2) inhibitors within 2 weeks prior to Screening. Short-term use is defined as a duration of ≤4 weeks of continuous use.
11. In the judgment of the principal investigator, participants who are likely to be non-compliant or uncooperative during the study.
12. Has known non-diabetic kidney disease (such as autosomal dominant polycystic kidney disease (ADPCKD), Immunoglobulin A (IgA) nephropathy, focal segmental glomerulosclerosis, or obstructive uropathy). Hypertensive nephrosclerosis superimposed on diabetic kidney disease is acceptable.
13. Had a previous renal transplant.
14. Has hypersensitivity to other monoclonal antibodies (mAb) or to any component of the formulation of MLN1202.
15. Has history of malignancy within the previous 5 years (with the exception of adequately treated basal cell or squamous cell carcinoma of the skin).
16. Is symptomatic with dysuria, and has a positive urine culture at screening.
17. If female, the subject is pregnant or lactating or intending to become pregnant before, during, or within 1 month after participating in this study; or intending to donate ova during such time period and for 56 days (8weeks) afterwards.
18. If male, the subject intends to donate sperm during the course of this study or for 12 weeks thereafter.
