Long-Term Safety Study Of Inhaled Insulin (CP-464,005, Inhaler) In Japanese Patients With Type1 or Type2 Diabetes

5 octobre 2009 mis à jour par: Pfizer

An Open-Label, Uncontrolled Long-Term Safety Study Of CP-464,005 (Inhaled Insulin) In Japanese Patients With Type 1 Or Type 2 Diabetes

Assess the safety and toleration of CP-464,005 and Inhaler following 1-year (52 week) administration to Type 1 and Type 2 diabetes patients (non-smokers)

Aperçu de l'étude

Description détaillée

Pfizer announced in October 2007 that it would stop marketing CP-464,005. At that time recruitment for study, A2171105 was placed on hold. Nektar, the company from which Pfizer licensed CP-464,005, announced on April 9, 2008 that it had stopped its search for a new marketing partner. As a result, study A2171105 was terminated on April 10, 2008. Neither safety nor efficacy reasons were the cause of the study termination.
