Trial Outcomes & Findings for Long-Term Safety Study Of Inhaled Insulin (CP-464,005, Inhaler) In Japanese Patients With Type1 or Type2 Diabetes (NCT NCT00527397)

NCT ID: NCT00527397

Last Updated: 2009-10-15

Results Overview

Self-monitoring blood glucose levels obtained at each observation point minus that at baseline.

Recruitment status

TERMINATED

Study phase

PHASE3

Target enrollment

Participant Flow

10 centers in Japan.

As a result of Pfizer's decision (18 Oct 2007) to return the worldwide rights for CP-464,005 (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.

PRIMARY outcome

Timeframe: One year

Population: This endopoint was not analyzed because of small numbers of subjects due to early termination

Self-monitoring blood glucose levels obtained at each observation point minus that at baseline.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 26 weeks

Population: Includes all subjects who received at least one dose of study drug. Number of subjects with evaluable data presented as n=type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus Using Insulin, Type 2 Diabetes Mellitus Not Using Insulin, respectively.

The mean of daily inhaled insulin dose. The dose of inhaled insulin was adjusted based on the results of self-monitoring of blood glucose before each meal.The end of treatment values were calculated each subject's last observed value up to 26 weeks.
