PLYMOUTH MEETING, Pa., Oct. 6 /PRNewswire-FirstCall/ -- Genaera Corporation today reported data from its second Phase 1 clinical trial of trodusquemine (MSI-1436), Genaera's lead drug candidate for the treatment of type 2 diabetes and obesity. MSI-1436 is a novel inhibitor of PTP1B, a validated molecular target that controls the function of both the leptin and insulin pathways to normalize glucose and decrease appetite. In the study, MSI-1436 was found to be well-tolerated and no serious adverse events were experienced at likely clinical doses. There were indications of dose-dependent weight loss seen in the obese and overweight type 2 diabetic subjects. Data were presented over the weekend in a poster entitled, "Trodusquemine impact on glucose/insulin and other parameters in type 2 diabetics," at the North American Association for the Study of Obesity (NAASO) Annual Meeting in Phoenix, Arizona.
"We are pleased to have once again demonstrated the positive adverse event profile, good tolerability and predictable pharmacokinetics (PK) of MSI-1436, consistent with the results achieved in our previous clinical and preclinical studies," stated Michael Gast, M.D., Ph.D., Executive Vice President and Chief Medical Officer of Genaera. "Subjects in this study also evidenced modest dose-proportional weight loss which we hope to verify in our forthcoming Phase 1b study later this year. We believe these results continue to support the potential of MSI-1436 to provide an exciting, new treatment option for patients afflicted by both diabetes and obesity."
Study MSI-1436C-103 was a double-blind, randomized, placebo-controlled safety and PK study involving obese or overweight adult male and female diabetic volunteers poorly controlled on metformin. Five subjects in each of four dosing groups received MSI-1436 while two subjects in each dosing group received placebo. Participants were studied at two research sites to evaluate the safety, tolerability and PK of single intravenous doses of 3, 6 or 10 mg/m2 of MSI-1436. The study began with a four day in-house study period with post dosing evaluations conducted on study days seven, 14 and 21.
Results suggest that MSI-1436 is well-tolerated, with no serious adverse events, no severe adverse events, and no dose-limiting toxicities or early discontinuations reported. In addition to the favorable adverse event profile seen in the study, the single-dose PK of MSI-1436 was found to be linear and slightly greater than dose proportional following intravenous dosing.
A Phase 1b multiple ascending dose study in obese type 2 diabetics (Study 102) is slated to initiate in 4Q 2008 in which one of three doses of MSI-1436 will be administered every three days over a 23 day period to evaluate primary outcomes of safety and multiple dose PK and secondary outcomes of oral glucose tolerance and insulin sensitivity, satiety and weight loss.
About Trodusquemine (MSI-1436)
Trodusquemine is a centrally and peripherally-acting appetite suppressant and the first highly selective inhibitor of protein tyrosine phosphatase 1B (PTP1B). PTP1B is central to controlling the function of both the leptin and insulin pathways. By inhibiting PTP1B, MSI-1436 is expected to decrease appetite and normalize blood sugar. Trodusquemine has produced consistent, sustainable weight loss in a variety of animal models and appears to overcome metabolic readjustment, which often limits sustained weight loss during caloric restriction. In addition, trodusquemine has shown the ability to reverse co-morbidities associated with obesity such as abnormal glucose metabolism and cholesterol elevation.
