Item 1.01Entry into a Material Definitive Agreement.

On August 22, 2016, Blueprint Medicines Corporation (the “Company”) entered into a Master Collaboration Agreement and a project schedule (collectively, the “Agreement”), with QIAGEN Manchester Limited (“QIAGEN”). Pursuant to the Agreement, QIAGEN has agreed to develop and commercialize an assay as a companion diagnostic test to identify gastrointestinal stromal tumor (“GIST”) patients with the PDGFRα D842V mutation for use with BLU-285, one of the Company’s lead drug candidates. 

Under the Agreement, QIAGEN is responsible for developing, and obtaining and maintaining regulatory approvals for, the companion diagnostic test in the United States, the European Union, Canada and such other countries as the parties may mutually agree. In addition, QIAGEN has agreed to use commercially reasonable efforts to manufacture the companion diagnostic test and to make the companion diagnostic test commercially available in the United States, the major European markets, Canada and such other countries as the parties may mutually agree. Under the Agreement, QIAGEN has agreed to undertake specified actions to minimize the risk of an inability of supply occurring for the manufacture of the companion diagnostic test, and if QIAGEN elects not to commercialize the companion diagnostic test itself in any country, QIAGEN has agreed to procure alternative distribution channels or otherwise supply the companion diagnostic test to the Company in such quantities and upon commercially reasonable terms as necessary in order to enable the Company to market BLU-285 for GIST patients with the PDGFRα D842V mutation in combination with the companion diagnostic test. QIAGEN remains free to develop its companion diagnostic tests for use with a third party’s therapeutic products, and the Company remains free to engage a third party to develop other companion diagnostic tests for use with BLU-285 and any of the Company’s other drug candidates.

Subject to the terms of the Agreement and upon achievement of specified technical and development milestones, the Company will pay QIAGEN an aggregate amount of up to approximately $6.1 million over the term of the development program for the companion diagnostic test for BLU-285. In addition, the Company will reimburse QIAGEN for certain pass-through costs. These amounts are subject to adjustment if the parties determine that changes in the scope of the development program are required. In addition, QIAGEN will retain all proceeds from the commercialization of the companion diagnostic test.

The Agreement expires on the later to occur of (i) the fifth anniversary of the Agreement and (ii) the term of any project schedule executed under the Agreement. The Company may terminate the Agreement or a project schedule (i) upon 30 days’ prior written notice to QIAGEN if such termination is due to the Company’s cessation of further development of BLU-285 or any other drug candidate covered by a project schedule executed under the Agreement and (ii) for convenience upon 120 day’s prior written notice to QIAGEN. Either party may terminate the Agreement or any project schedule executed under the Agreement, as applicable, upon a material breach of the other party that is not cured within 30 days after written notice of such breach or immediately upon the bankruptcy or insolvency of the other party. In the event of a termination of the Agreement by the Company, the Company will be obligated to pay QIAGEN wind-down and other costs and final payments.

The foregoing description of the material terms of the Agreement is qualified in its entirety by reference to the complete text of the Agreement, which the Company intends to file, with confidential terms redacted, with the Securities and Exchange Commission as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2016.
