Item 1.01. Entry into a Material Definitive Agreement


      On July 18, 2006, Theravance, Inc., a Delaware corporation ("Theravance") and Astellas Pharma Inc., a Japanese corporation ("Astellas") amended their license, development and commercialization agreement dated November 7, 2005 to include Japan in their collaboration for the development and commercialization of Theravance's investigational antibiotic, telavancin (the "Amendment").

      Under the terms of the Amendment, Theravance grants Astellas an exclusive license to develop and commercialize telavancin in Japan, and Astellas will pay Theravance a $10 million up-front payment. The Amendment also provides for a $5 million regulatory milestone payment to Theravance if the marketing and sale of telavancin is approved by Japanese regulatory authorities. In addition, Theravance is entitled to royalties on global sales of telavancin that will now include sales in Japan, and which, on a percent basis, range from the high teens to the upper twenties. Astellas has the right to terminate the collaboration in Japan for cause in certain circumstances, including those based on the results of the complicated skin and skin structure infections (cSSSI) clinical studies currently being conducted by Theravance.

      Under the terms of the collaboration agreement, as amended, Theravance will lead the development of telavancin for cSSSI and hospital-acquired pneumonia (HAP) and collaborate substantially with Astellas in marketing in the U.S. for the first three years. Astellas will lead all other development, regulatory, manufacturing, sales and marketing activities worldwide, including Japan. Theravance will be responsible for substantially all costs to develop telavancin for cSSSI and HAP, and Astellas will be responsible for substantially all costs associated with further development and commercialization of telavancin.

      In addition to the license rights to telavancin in Japan, Astellas will also receive an option to further develop and commercialize TD-1792 in Japan. TD-1792 is a unique heterodimer antibiotic compound that combines the antibacterial activities of a glycopeptide and a beta-lactam in one molecule. TD-1792 is currently in Phase 1 human clinical studies.
