Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Current research indicates that TTP488 may be a viable agent for the treatment of diabetic nephropathy. The purpose of this study is to determine the safety and efficacy of a six-month regimen of daily orally-administered TTP488 to patients with diabetic nephropathy.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male or female outpatients 31 years of age or older.
* Females must no longer be of child-bearing potential, must have a negative serum pregnancy test, and cannot be breast-feeding.
* Non-vasectomized male must be willing to abstain from sexual intercourse or willing to use a condom in addition to having their female partner use another form of contraception.
* Diagnosis of probable Type 2 diabetes after the age of 30 and for at least 6 months prior to the screening visit and: not requiring insulin within first year of diagnosis; no history of diabetic ketoacidosis (DKA); body mass index (BMI) of 40 or less at the screening visit
* Presence of persistent albuminuria with a UACR of 6.7 - 203 mg/mmol Must be taking the highest tolerated dose of an angiotensin converting enzyme (ACE) inhibitor or an angiotensin II receptor blocker (ARB) and have been maintained on that dose for at least 3 months prior to the Baseline visit
* Blood pressure(BP) must be stable and well controlled by the judgement of the investigator (goal of the control of BP is 130/80 or less). If required, the use of anti-hypertensives in addition to an ACE inhibitor or an ARB is acceptable.
* Patients with a calculated creatinine clearance of greater than or equal to 30 mL/min and without the presence of clinically significant hematuria or red or white cell casts can be included in the study.

Exclusion Criteria

* Diagnosis of Type 1 diabetes
* Hemoglobin A1c (HbA1c) \>10%
* Females cannot be breast-feeding
* Known renal artery stenosis
* Calculated creatinine clearance \<30 mL/min or the presence of clinically significant hematuria of red or white cell casts
* Chronic use of NSAIDs or more than 1 g/day of aspirin
* QTc \>450 msec for females or \>430 msec for males (a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle)
* Known family history of prolonged QT syndrome
* History of symptomatic congestive heart failure within the last 2 years
* History of syncope in the lst 2 years or recurrent hypokalemia, including that caused by diuretics
* Myocardial infarction or signs or symptoms of unstable coronary artery disease with the last year
* Pulmonary disease or evidence of clinically significant pulmonary symptoms.
* Active neoplastic disease. (Excised cutaneous basal cell carcinomas are not excluded). Patients with stable prostate cancer may be included at the discretion of the Medical Monitor.
* Any clinically significant hematologic or coagulation disorder
* Any clinically significant hepatic disease
* Use of excluded medications: drugs known to significantly increase QTc and/or have increased risk of torsades de point, immunosuppressive agents, cancer chemotherapeutic agents, oral corticosteroids other than maintenance doses equivalent to 7.5 mg prednisone per day, and radiotherapy
* Use of an investigational drug within 30 days or within 5 half-lives of the investigational agent, whichever is longer, or use of an investigational medical device within 2 weeks before or after the study
* Any other disease or condition that, in the opinion of the investigator, makes the patient unsuitable to participate in this study
