"In 2016, we focused our efforts on the development of tucatinib for late-stage HER2-positive metastatic breast cancer for patients with and without brain metastases and amended our ongoing HER2CLIMB study by increasing the sample size so that, if successful, the trial could serve as a single pivotal trial to support registration," said Scott Myers, President and CEO of Cascadian Therapeutics. "For 2017, we have prioritized our resources on expanding HER2CLIMB globally and exploring the potential utility of tucatinib in additional HER2-positive expressing cancers. With a global development plan underway, clarity on a U.S. regulatory pathway and a solid financial position, we have set the foundation to execute our strategy."

Fourth Quarter and Recent Highlights
Tucatinib — targeted HER2 inhibitor
In December 2016, researchers presented updated data from the Company’s ongoing Phase 1b Triplet combination study (tucatinib with capecitabine and trastuzumab) at the 2016 San Antonio Breast Cancer Symposium. This Triplet combination continued to be well tolerated and showed an updated median progression-free survival of 7.8 months, an overall response rate of 61 percent and a median duration of response of 10 months. Patients treated with the Triplet combination previously received a median of 3 HER2-targeted agents, such as trastuzumab, pertuzumab, lapatinib and T-DM1.
In December 2016, the Company announced that, following a meeting with the U.S. Food and Drug Administration (FDA) and discussions with the Company’s external Steering Committee, the Company amended the HER2CLIMB trial of tucatinib by increasing the sample size so that, if successful, the trial could serve as a single pivotal study to support a new drug application.
In October 2016, the Company announced presentation of data from the ongoing Phase 1b Triplet combination study (tucatinib with capecitabine and trastuzumab) at the European Society for Medical Oncology 2016 Congress that showed clinical activity in HER2-positive metastatic lesions to the skin.
CASC-578 — a novel Chk1 cell cycle inhibitor
In December 2016, the Company completed a non-human pharmacology study to evaluate the impact of CASC-578 on multiple cardiovascular endpoints. The results indicate CASC-578 has an acceptable profile at the doses tested and warrants further study of the drug in both single agent and combination settings.
Corporate
In January 2017, the Company strengthened its balance sheet through an underwritten public offering, resulting in net proceeds of approximately $88 million.
Fourth Quarter and Full Year 2016 Financial Results
Cash, cash equivalents and investments totaled $62.8 million as of December 31, 2016, compared to $56.4 million at December 31, 2015, an increase of $6.4 million, or 11.3 percent. The increase was primarily due to the result of net proceeds of $43.3 million from the Company’s June 2016 financing offset by cash used to fund operations of $36.9 million.
Net loss attributable to common stockholders for the three months ended December 31, 2016 was $10.5 million, or $0.47 per share, compared to a net loss attributable to common stockholders of $9.1 million, or $0.58 per share, for the same period in 2015. The $1.4 million increase in net loss attributable to common stockholders for the quarter was primarily due to an increase in research and development expense associated with the development of the Company’s product candidates and an increase in general and administrative expense, which included expenses related to headcount and the Company’s adoption of the Retention Plan in early January 2016.
Net loss attributable to common stockholders for the year ended December 31, 2016 was $60.3 million, or $3.13 per share, compared to a net loss attributable to common stockholders of $32.6 million, or $2.02 per share, for the same period in 2015. The increase in net loss attributable to common stockholders for the year ended December 31, 2016 was primarily due to the intangible asset impairment charge of $19.7 million, which was the result of the mutual termination of the STC.UNM agreement. In addition, the increases in research and development expenses of $4.0 million, due to greater activity related to the development of the Company’s product candidates, and increases in general and administrative expenses of $8.3 million, primarily related to the retirement and separation of the former chief executive officer and other headcount-related expenses, contributed to the year-over-year increase in net loss. The Company also recognized a non-cash $2.6 million deemed dividend due to the beneficial conversion feature on the Series D convertible preferred stock. The increase in the net loss attributable to common stockholders was partially offset by a $6.9 million tax benefit during the year ended December 31, 2016.
