Item 1.02 Termination of a Material Definitive Agreement.
On November 29, 2005, the registrant, Cubist Pharmaceuticals, Inc. (Cubist), provided notice to DSM Capua, S.p.A. (DSM) that Cubist is terminating the June 22, 2000 Manufacturing and Supply Agreement (as amended) between Cubist and DSM (the MSA). The termination of the MSA shall be effective on May 27, 2006. Under the MSA, DSM supplies Cubist with Active Pharmaceutical Ingredient (API), or bulk drug substance, for Cubists IV antibiotic drug product, CUBICIN® (daptomycin for injection). Pursuant to the terms of the MSA, DSM shall supply Cubist with API in accordance with purchase orders that Cubist has submitted for delivery of API up until the effective date of termination. Cubist is terminating the MSA because Cubist no longer requires a second supplier of API, and Cubists other supplier, ACS Dobfar S.p.A. (ACS) is able to meet all of Cubists anticipated needs for CUBICIN API. There are no early termination penalties incurred by Cubist.
