The primary aim of this project is to determine if the study drug, Pyridorin™, at doses of 150mg orally twice daily or 300mg orally twice daily (compared to placebo), has an effect on the blood values (specifically serum creatinine) of subjects' who have kidney disease from type 2 diabetes.

Interventions

The study treatment is allocated to eligible subjects randomly. Subjects have an equal chance of being allocated to receive Pyridorin 150 mg orally, twice a day (BID) taken for 52 weeks or Pyridorin 300 mg orally BID taken for 52 weeks or placebo taken orally for 52 weeks.

All WOCBP must have a negative serum pregnancy test at the Screening Visit. At the Screening Visit, ALL patients must have a history of overt diabetic nephropathy. Patients must be receiving an Angiotensin Cenverting Enzyme Inhibitor (ACE-I) or an Angiotensin Receptor Blocker (ARB), for at least 3 months prior to the Qualifying Visit, where the dose of the ACE-I or the ARB is considered appropriate for that patient and has been stable for at least 2 months. Patients must be on stable blood pressure medications for 2 months prior to the Qualifying Visit. Appropriate Serum Creatiine and 24-hour urine PCR results at qualifying visit compared to Screening.

Exclusion criteria

Patients with type 1 diabetes; Patients with a diagnosis of chronic renal disease, other than diabetic renal disease, with or without hypertensive renal disease; Patients receiving a renin inhibitor or an aldosterone antagonist or a combination of an ACE-I and an ARB within 2 months of the Qualifying Visit; Patients with a history of solid organ transplantation; Patients with a history of myocardial infarction, coronary re-vascularization procedures (including percutaneous transluminal coronary angioplasty), cerebrovascular accident or transient ischemic attack within 1 month prior to the Screening Visit; Patients with a diagnosis of Class III or IV congestive heart failure at any time; Patients with a history of neoplastic disease (except basal or squamous cell carcinoma of the skin) within 5 years prior to the Screening Visit; Patients with any history of dialysis within 2 years prior to the Screening Visit; Patients in whom dialysis or renal transplantation is anticipated by their physician within 1 year after the Screening Visit; Patients who used SCr altering drugs within 1 month prior to the Screening Visit; Patients who require systemic immunosuppression therapy for >2 weeks (except for inhalant steroids); Patients with clinically significant liver disease or transaminase (alanine aminotransferase and aspartate aminotransferase) levels >2.5 x upper limit of normal measured at the Screening Visit; Patients with bilirubin levels >1.5 x upper limit of normal measured at the Screening Visit; Patients with a history of allergic or other adverse response to vitamin B preparations; Patients who require >50 mg of vitamin B6 daily; Patients who have a history of dysphasia and swallowing disorders; Patients with a history of hypersensitivity to Pyridorin or any of the excipients in the Pyridorin formulation; Patients who have taken pyridoxamine or any other investigational drug within 30 days prior to the Screening Visit, or have participated in a previous Pyridorin trial or another clinical trial within 30 days prior to the Screening Visit; Patients with a current history of drug or alcohol abuse; Patients unlikely to comply with the study protocol (e.g., an inability and unwillingness to participate in adequate training, an uncooperative attitude, inability to return for follow-up visits, or unlikelihood of completing the study); Women who are lactating, pregnant or intend to become pregnant during the course of the study
