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.
