Master Services Agreement with Cadila [Abstract]
Master Services Agreement with Cadila	Note 14 - 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, and subsequently in March 2013, in each case 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 2014, 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, 2013, the Company has purchased $2.4 million in services from Cadila pursuant to this agreement, which includes $0.8 million of services provided, since the beginning of 2013, by CPLB to the Company on behalf of Cadila pursuant to an October 2013 amendment authorizing such CPLB services. The Company plans to explore with Cadila ways to potentially address its remaining financial obligation and/or extend the time period during which the Company could utilize such services. 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 portion of its available cash and cash equivalents to pay Cadila for its shortfall in services purchased.
