Gilead Acquires Immunomedics for $21 Billion; Gilead Thus Adds Trodelvy, First-in-Class Antibody-Drug Conjugate Approved to Treat Triple-Negative Breast Cancer, with Promise in Other Forms of Breast Cancer and Additional Solid Tumors

On September 13, 2020, Gilead Sciences, Inc. (Nasdaq: GILD) and Immunomedics (Nasdaq: IMMU) announced that the companies have entered into a definitive agreement pursuant to which Gilead will acquire Immunomedics for $88.00 per share in cash. The transaction, which values Immunomedics at approximately $21 billion, was unanimously approved by both the Gilead and Immunomedics Boards of Directors and is anticipated to close during the fourth quarter of 2020. The agreement will provide Gilead with TrodelvyTM (sacituzumab govitecan-hziy), a first-in-class Trop-2 directed antibody-drug conjugate (ADC) that was granted accelerated approval by the U.S. FDA in April for the treatment of adult patients with metastatic triple-negative breast cancer (mTNBC) who have received at least two prior therapies for metastatic disease. Immunomedics plans to submit a supplemental Biologics License Application (BLA) to support full approval of Trodelvy in the United States in the fourth quarter of 2020. Immunomedics is also on track to file for regulatory approval in Europe in the first half of 2021.
