A First in Human, Single Dose, Safety and Tolerability Study of MKC253 Inhalation Powder in Healthy Adult Males

A Phase 1a, Single-Dose, Open-Label, Parallel, Ascending Dose, Controlled Safety and Tolerability Trial of Inhaled MKC253 in Healthy Adult Male Subjects

26 subjects will be enrolled into 5 different dose groups. The trial will consist of a screening, a dosing and a follow-up visit.

Dosing at visit 2, of MKC253 Inhalation Powder, Glucagon-Like Peptide-1 (GLP-1) will be given at 5 dose levels.

This Phase 1a , single-dose trial incorporates an open-label, ascending dose strategy to determine the safety & tolerability of MKC253 (GLP1/Technosphere®)Inhalation Powder.

The trial consists of a screening, dosing and a follow-up visit. Single dose administration of MKC253 occurs at the dosing visit. Five doses are being assessed: 0.05, 0.45, 0.75, 1.05 & 1.5 mg GLP-1. Dosing of each ascending cohort will occur after the Principal Investigator has reviewed all safety/tolerability data
