MannKind Corporation Announces Positive Results From a Phase 2b Dose-Ranging Study of Technosphere(R) Insulin in Patients With Type 2 DiabetesImproved Glycemic Control
No Deterioration of Pulmonary Function
No Weight Gain
VALENCIA, Calif., Jan. 17 (HSMN NewsFeed) -- MannKind Corporation (Nasdaq: MNKD ) today announced results from a phase 2b dose-ranging study of Technosphere® Insulin, an inhaled insulin formulation delivered via the Company's proprietary inhaler to patients with diabetes mellitus. Technosphere® Insulin was observed to improve glycemic control in a dose-dependent manner as measured by decreases in HbA1c levels (a measure of the average amount of blood sugar over the preceding three to four months) and in glucose excursions following a meal. Importantly, there was no indication of a negative effect on pulmonary function and no weight gain at any dose of Technosphere® Insulin over 12 weeks of treatment.
"The reduction in post-prandial glucose excursions is becoming of much greater interest due to the finding that these excursions may be involved in the pathogenesis of diabetic vascular disease. This study clearly showed that Technosphere® Insulin produced the desired effect on glycemic control," commented Dr. Irl Hirsch, an internationally-recognized expert on diabetes. Dr. Hirsch is a Professor of Medicine and the Medical Director of the Diabetes Care Center at the University of Washington Medical Center. He is also the 2004 recipient of the Outstanding Physician Clinician in Diabetes Care Award by the American Diabetes Association.
The phase 2b dose-ranging study was designed to evaluate the effect of different mealtime doses of Technosphere® Insulin added to a single fixed daily injection of basal insulin glargine (Lantus®) in patients with type 2 diabetes. In total, 227 patients were studied. Patients were followed on their existing therapy for four weeks, then transferred to insulin glargine, and subsequently randomized to receive, in a double blind fashion, either inhaled placebo (consisting of Technosphere® particles only) or Technosphere® Insulin at dosages of 14, 28, 42 and 56 units. Patients who received Technosphere® Insulin were force-titrated to their pre-assigned dose and remained on that dose for the duration of the study. HbA1c levels and post-prandial glucose excursions were assessed at the initial visit, at the start of randomized treatment and at study completion. Comparisons were made between the groups receiving Technosphere® Insulin and the group receiving placebo. Pulmonary safety was assessed by serial measurements of lung function, including forced expiratory volume (FEV1) and carbon monoxide lung diffusing capacity (DLco).
The study demonstrated that the addition of Technosphere® Insulin to insulin glargine produced a statistically significant, dose-dependent reduction in HbA1c levels and in post-prandial glucose excursions. In patients treated for eight weeks at 56 units (n=45), the mean reduction in percent HbA1c levels was 0.79 below that observed in the placebo group (p=0.0002). Also, at 56 units, the maximal post-prandial glucose excursion was reduced to only 34 mg/dl, a 63% reduction compared to the placebo group (p<0.0001). No reduction of pulmonary function was observed over 12 weeks, as measured by FEV1 and DLco. Additionally, no change in weight was observed at any dose in the group receiving Technosphere® Insulin, and no severe hypoglycemic episodes were seen throughout the study.
Dr. Peter Richardson, Chief Scientific Officer of MannKind, commented, "This study met its primary objective and further supports the Technosphere® Insulin dosing regimen currently being evaluated in our phase 3 trials. The results are consistent with the Company's previous studies on Technosphere® Insulin that demonstrated improved glycemic control in patients with diabetes, reduced post-prandial glucose excursions, no deterioration in pulmonary lung function, and no weight gain associated with Technosphere® Insulin at any of the dosage levels tested. Collectively, these data demonstrate a potential advantage of Technosphere® Insulin over standard insulin therapies."
