BOTHELL, WA & SEATTLE, WA, USA I January 31, 2018 I Seattle Genetics, Inc. (Nasdaq:SGEN) and Cascadian Therapeutics, Inc. (Nasdaq:CASC) today announced the signing of a definitive merger agreement under which Seattle Genetics has agreed to acquire Cascadian Therapeutics. Under the terms of the agreement, Seattle Genetics will pay $10.00 per share in cash, or approximately $614 million. The transaction was unanimously approved by the Boards of Directors of both companies.
Cascadian Therapeutics’ most advanced program is tucatinib, an investigational oral, small molecule tyrosine kinase inhibitor (TKI) that is highly selective for HER2, a growth factor receptor that is overexpressed in multiple cancers, including breast, colorectal, ovarian and gastric. Tucatinib is currently being evaluated in a randomized global pivotal trial called HER2CLIMB for patients with HER2-positive (HER2+) metastatic breast cancer, including patients with or without brain metastases. Tucatinib has been evaluated as a single agent and in combination with both chemotherapy and other HER2-directed agents including Herceptin® (trastuzumab) and Kadcyla® (trastuzumab emtansine). Results from phase 1b trials showed that the combination of tucatinib, capecitabine and trastuzumab was generally well-tolerated and demonstrated clinical activity in patients with and without brain metastases. The data support the ongoing pivotal trial and the potential role of tucatinib in earlier lines of metastatic breast cancer.
“This acquisition would enhance our late-stage clinical pipeline with a potentially best-in-class, orally available and highly selective TKI for patients with HER2-positive metastatic breast cancer,” said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. “Tucatinib would complement our existing pipeline of targeted cancer therapies, provide a third late-stage opportunity for a commercial product in solid tumors and expand our global efforts in breast cancer. It also leverages our broad expertise and resources to advance and expand the tucatinib program for patients. Beyond breast cancer, we believe there may be opportunities for tucatinib in other tumor types, such as HER2-positive metastatic colorectal cancer. Cascadian’s pipeline also includes a preclinical immuno-oncology agent. We look forward to welcoming the team at Cascadian Therapeutics and continuing the momentum of the tucatinib development program.”
“This agreement represents a very positive outcome for patients with HER2-expressing cancers, our employees and for our stockholders,” said Scott D. Myers, President and Chief Executive Officer of Cascadian Therapeutics. “Seattle Genetics has the development and commercial capabilities and the resources needed to more fully realize the potential of tucatinib as a new best-in-class treatment option for metastatic breast cancer, colorectal cancer and potentially for other indications.”
Terms of the Transaction
Under the terms of the definitive merger agreement, Seattle Genetics will commence a tender offer on or about February 8, 2018 to acquire all of the outstanding shares of common stock of Cascadian Therapeutics for $10 per share in cash. This represents a 69 percent premium to the closing price of Cascadian Therapeutics’ common stock on Tuesday, January 30, 2018, and a 139 percent premium to its 30-day volume weighted average stock price. The tender offer is subject to customary closing conditions, including the tender of at least a majority of the outstanding shares of Cascadian Therapeutics common stock (on a fully diluted basis) and the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Following the closing of the tender offer, a wholly-owned subsidiary of Seattle Genetics will merge with and into Cascadian Therapeutics, with each share of Cascadian Therapeutics common stock that has not been tendered being converted into the right to receive the same $10 per share in cash offered in the tender offer. The transaction is anticipated to close in the first quarter of 2018.
In connection with the transaction, Seattle Genetics has secured a financing commitment in the amount of $400 million from Barclays and JPMorgan-Chase Bank. The balance of the consideration will be provided from cash on hand.
Leerink Partners LLC is acting as lead financial advisor to Seattle Genetics. Barclays and J.P. Morgan Securities LLC are also acting as financial advisors on the transaction. Perella Weinberg Partners LP is acting as financial advisor to Cascadian Therapeutics. Legal counsel for Seattle Genetics is Sullivan & Cromwell LLP and legal counsel for Cascadian Therapeutics is Reed Smith LLP. Goodwin Procter LLP acted as special counsel for the Cascadian Therapeutics Board of Directors and Board transaction committee.
Seattle Genetics Preliminary Financial Results
In conjunction with today’s announcement, Seattle Genetics separately reported preliminary unaudited consolidated financial results as of and for the quarter and year ended December 31, 2017 as follows:
|Three Months Ended
December 31, 2017
|Year Ended December 31,
|Total revenues||$128 million to $130 million||$481 million to $483 million|
|ADCETRIS net product sales in the U.S. and Canada||$82 million to $84 million||$306 million to $308 million|
Total revenues increased from the comparable periods in 2016 primarily as a result of increased ADCETRIS net product sales. ADCETRIS net product sales increased from the comparable periods in 2016 primarily due to an increase in sales volume and, to a lesser extent, price increases. The increases in sales volumes in both periods were driven primarily by increased use of ADCETRIS across multiple lines of therapy in Hodgkin lymphoma and for the treatment of other malignancies.
In addition, as of December 31, 2017, Seattle Genetics had approximately $413 million in cash and cash equivalents and short-term investments.
