Participant Flow

This was a single site with first subject screened 24 Apr 2008

Subjects assigned at Visit 2 to either: 2 15 U cartridges (TI Inhalation Powder A) or 1 30 U cartridge (TI Inhalation Powder B). At Visit 3 each subject was crossed over to the other treatment group. At Visit 4 subjects received a single sc injection of 10 IU of insulin lispro to 1 of 3 possible injection sites: arm, leg, or abdomen.
