Item 8.01 Other Events

MacroGenics, Inc. (the "Company") and Les Laboratoires Servier and Institut de Recherches Servier (collectively, "Servier") are parties to an option for a license agreement dated November 24, 2011 (the "Agreement"). Pursuant to the Agreement, the Company provided interim data from its ongoing Phase 1 monotherapy clinical study of enoblituzumab (MGA271) to Servier in July 2015. After delivery of that data, Servier had 90 days in which to exercise an option for commercialization and development rights to enoblituzumab in Europe and other countries. On October 27, 2015, Servier notified the Company that it would not be exercising this option.  The Agreement has now expired in accordance with its terms. As a result, the Company now controls worldwide development and commercialization rights for enoblituzumab.

The collaboration with Servier related to the development of Dual-Affinity Re-Targeting (DART) molecules is unaffected by the expiration of this Agreement.

On October 28, 2015, the Company issued a press release regarding expiration of the Agreement, a copy of which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
