Keryx issued positive results from a phase III trial of Zerenex for the treatment of hyperphosphatemia in patients with end-stage renal disease on dialysis. This multicenter, randomized, open-label trial enrolled 150 subjects on hemodialysis. Following a two-week washout period, the subjects were randomized to fixed doses of Zerenex 1, 6 or 8 grams per day, for a treatment period of 28 days. The primary endpoint was to demonstrate a dose response in the change of serum phosphorous from baseline (end of washout period) to end of the treatment period (day 28). The study met the primary endpoint, with the regression analysis indicating a highly statistically significant dose response (p<0.0001). In addition, a statistically significant dose response increase in serum bicarbonate was observed and there was no clinically meaningful change in serum calcium. Zerenex appeared to be safe and well-tolerated.

CuraGen reported positive results of a phase I trial of CR002, their monoclonal antibody for the treatment of kidney inflammation. Trial data indicated a positive safety profile, with no serious adverse events reported and good overall tolerability. Pharmacokinetic data indicated that meat elimination half-life was 20.1 to 34.2 days, and pharmacodynamic results indicated binding to the antibody's target molecule (platelet derived growth factor-D) for durations exceeding 20 days. This open- label placebo-controlled study enrolled 40 healthy volunteers, who received one of five single doses of the drug (0.3 mg/kg to 30 mg/kg) or placebo, with subsequent 3 month observational follow-up.

LAB International has announced positive results of a phase I/II trial of their Growth Hormone Releasing Hormone (GHRH) analog, being developed as an inhalable treatment for growth hormone (GH) deficiency caused by a number of diseases, including HIV, chronic renal failure and lipodystrophy. The drug was found to be safe and well tolerated, with no significant adverse events. Furthermore, the drug produced significant increases in serum GH levels up to 12 hours after treatment at all dosing regimens, and demonstrated a higher-than-expected efficacy for this endpoint. No impact on normal nocturnal GH secretion was observed. The placebo-controlled, single-dose safety and efficacy cross-over study enrolled a total of 10 healthy volunteers, all of whom received randomized sequential dosing regimens of 5-25 ug/kg and placebo. LAB announced plans for both indication-driven phase II trials and another phase I/II dose-ranging trial to establish minimum therapeutic dose.

Phase III trial results indicate that Fosrenol (lanthanum carbonate), a phosphate binder for use in dialysis subjects, did not adversely affect bone over 12 months of continuous therapy. Data also showed that there was no evolution towards low bone turnover states in lanthanum-treated subjects. The multicenter trial included 98 subjects beginning renal dialysis for the first time. Subjects were randomized to receive either lanthanum carbonate or calcium carbonate, which was titrated to a well-tolerated dose that gave acceptable control of serum phosphate. Bone biopsies were taken at the beginning and end of the 12-month study, and blood samples were taken at each visit. Fosrenol is being developed by Shire Pharmaceuticals and AnorMED.
