Gilead Sciences to acquire Immunomedics in a $21 billion deal

SACRAMENTO: Gilead Sciences Inc. and Immunomedics have entered into a definitive agreement pursuant to which Gilead will acquire Immunomedics for $88/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. Food and Drug Administration (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.

In the Phase 3 ASCENT study, which was halted early due to efficacy based on the unanimous recommendation of the independent Data Safety Monitoring Committee, Trodelvy significantly improved progression-free survival (PFS) and overall survival (OS) in previously treated patients with advanced mTNBC. Detailed results from this study are expected to be presented at the upcoming European Society for Medical Oncology (ESMO) Virtual Congress 2020.

Beyond mTNBC, Trodelvy is also being studied in an ongoing Phase 3 trial in third line HR+/HER2- breast cancer and a registrational Phase 2 study in bladder cancer. Additional ongoing studies are evaluating the potential of Trodelvy as a treatment for non-small cell lung cancer and other solid tumor types. Trodelvy is being studied as both a monotherapy and in combination with checkpoint inhibitors and other non-immuno-oncology products by Immunomedics and independent investigators. Additional clinical data for Trodelvy in bladder cancer and other solid tumors will also be presented at ESMO this coming week.

“This acquisition represents significant progress in Gilead’s work to build a strong and diverse oncology portfolio. Trodelvy is an approved, transformational medicine for a form of cancer that is particularly challenging to treat. We will now continue to explore its potential to treat many other types of cancer, both as a monotherapy and in combination with other treatments,” said Daniel O’Day, Chairman and Chief Executive Officer, Gilead Sciences.

“We look forward to welcoming the talented Immunomedics team to Gilead so we can continue to advance this important new medicine for the benefit of patients with cancer worldwide.”

“We are very pleased that Gilead recognized the value of Trodelvy – both for the important role it has already begun to play for patients with metastatic triple-negative breast cancer and for its potential to help many other patients with cancer in the future,” said Behzad Aghazadeh, PhD, Executive Chairman of Immunomedics. “We are excited for the opportunities ahead of us as we join with Gilead to advance our shared mission in defeating cancer. By working with Gilead, we have the opportunity to accelerate our progress and improve care for patients in need of new therapies.”

Under the terms of the merger agreement, a wholly-owned subsidiary of Gilead will promptly commence a tender offer to acquire all of the outstanding shares of Immunomedics’ common stock. The $88/share acquisition price represents a 108 percent premium to Immunomedics’ closing price on September 11, 2020. Following successful completion of the tender offer, Gilead will acquire all remaining shares not tendered in the offer through a second step merger at the same price as the tender offer.

The consummation of the tender offer is subject to various conditions, including a minimum tender of at least a majority of outstanding Immunomedics shares, the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.

The tender offer is not subject to a financing condition and will be funded through approximately $15 billion in cash on hand, as well as approximately $6 billion in newly issued debt. Gilead expects to retain an investment grade credit rating following this transaction and this agreement does not alter Gilead’s stated capital allocation strategy or its commitment to maintain and grow its dividend over time.
