Master Services Agreement with Cadila [Abstract]
Master Services Agreement with Cadila	Note 11 - Master Services Agreement with Cadila In connection with the JV with Cadila, the Company entered into a master services agreement, which the Company and Cadila amended in July 2011 to extend the term by one year for which services can be provided by Cadila under this agreement. Under the revised terms, if by March 2013, the amount of services provided by Cadila under the master services agreement is less than $7.5 million, the Company will pay Cadila the portion of the shortfall amount that is less than or equal to $2.0 million and 50% of the portion of the shortfall amount that exceeds $2.0 million. Through September 30, 2012, the Company has purchased $0.4 million in services from Cadila pursuant to this agreement.

The Company can provide no assurance, however, that these efforts will be successful. If the Company fails to negotiate a change in this arrangement, the Company expects that it will be obligated to spend a significant portion of its available cash and cash equivalents to pay Cadila for our shortfall in services purchased.
