Description of intervention(s) / exposure
This was a randomized, double-blind, Placebo-controlled study in adult patients with diabetic nephropathy. Upon completion of screening, Enrolment and a 3-week Placebo-run-in period, patients were randomized to treatment with 1200 mg/day, GC811007 (taken as two 300-mg capsules twice daily, BID, before meals) or Placebo, administered as 2 identical 300-mg capsules taken orally twice daily (BID) before meals for 6 months. Patients underwent safety and efficacy assessments during clinic visits at Months 0, 2, 4, and 6. Telephone follow-up interviews were conducted 2 weeks after the final clinic visit.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This was a randomized, double-blind, Placebo-controlled study in adult patients with diabetic nephropathy. Upon completion of screening, Enrolment and a 3-week Placebo-run-in period, patients were randomized to treatment with 1200 mg/day GC811007 or Placebo, administered as 2 identical 300-mg capsules taken orally twice daily (BID) before meals for 6 months.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A variable block randomisation schedule was used where a random number was assigned to each drug treatment pack and each pack sequentially assigned to blocks of varying sizes. Within each block, the drug treatment packs were sorted by random number and packs associated with the lower half of the random number set were assigned placebo, and those associated with the higher half were assigned active treatment. Assignment within blocks ensured that the number of active and placebo packs was equal once each block was full, to attain a balanced design in the event of early termination. The variable block size was a protection against unblinding.

Summary
Brief summary
This pilot study was designed to assess whether treatment with GC811007 would arrest the decline in renal function and the associated progression of diabetic retinopathy, peripheral neuropathy and autonomic neuropathy in patients with Type 2 diabetes mellitus. The safety and tolerability of GC811007 also were assessed.
