NCT ID: NCT00437489

Last Updated: 2009-05-11

Results Overview

Mean change of hemoglobin A1c (HbA1c %) from baseline to week 16

Recruitment status

TERMINATED

Study phase

PHASE4

Target enrollment

49 participants

Primary outcome timeframe

From baseline to week 16

Participant Flow

Five centers in the Philippines, 2 centers in Singapore, 1 center in Hong Kong, and 1 center in Pakistan enrolled subjects.

As a result of Pfizer's decision (18Oct2007) to return the worldwide rights for Exubera (insulin human \[rDNA origin\]) Inhalation Powder) to Nektar, from which Pfizer licensed inhaled insulin technology, it was decided to terminate this study before it had recruited targeted number of subjects and followed them for the per protocol specified period.

PRIMARY outcome

Timeframe: From baseline to week 16

Population: Full analysis set (FAS) population - descriptive statistics were produced using last observation carried forward (LOCF) for Week 16, therefore all subjects are included in the Week 16 data.

SECONDARY outcome

Timeframe: From baseline to week 16

Population: FAS - descriptive statistics were produced using LOCF for Week 16, therefore all subjects are included in the Week 16 data.

Mean change of fasting plasma glucose, and overall absolute (based on the mean of 7-point home blood glucose monitoring (HGM) values), pre- and post-meal blood glucose (based on the mean of pre- or post-meal HGM values). Change from pre- to post-meal blood glucose based on the mean of difference of pre-meal HGM values from post-meal HGM values.

SECONDARY outcome

Timeframe: up to week 4 or 16

Population: FAS Population

Monthly event rate was calculated as the daily event rate multiplied by 30, and the daily event rate was calculated as the total number of events divided by the days in study up to the specified timepoint (ie, Week 4 or Week 16).
