Active Comparator: Control Drug: Insulin lispro (Humalog)
Subcutaneous insulin regimen of pre-prandial insulin lispro and administration of insulin glargine QD.
Experimental: Experimental Drug: Inhaled Human Insulin (Exubera®)

Detailed Description:
Pfizer announced in October 2007 that it would stop marketing Exubera®. At that time recruitment for study, A2171035 was placed on hold. Nektar, the company from which Pfizer licensed Exubera®, announced on April 9, 2008 that it had stopped its search for a new marketing partner. Accordingly, there will be no commercial availability of Exubera®. As a result, study A2171035 was terminated on May 12, 2008. Neither safety nor efficacy reasons were the cause of the study termination.
