Cascadian Therapeutics Reports Third Quarter 2016 Financial Results and Provides Corporate Update

SEATTLE, Nov. 07, 2016 (GLOBE NEWSWIRE) -- Cascadian Therapeutics CASC, a clinical-stage biopharmaceutical company, today provided third quarter highlights and reported financial results for the quarter ended September 30, 2016.

"We continue to make strides on the clinical development front as we advance tucatinib in combination for patients with metastatic HER2+ breast cancer, including those with and without brain metastases," said Scott Myers, CEO of Cascadian Therapeutics. "There is significant need for improved therapies in this disease, and we continue to be impressed by the favorable safety profile observed in the tucatinib combination studies to date when compared with other HER2 therapies, as well as its potential to treat systemic disease and positively impact brain metastases."

Mr. Myers added, "We are looking forward to the presentation of updated clinical data from our ongoing Phase 1b ‘Triplet' study of tucatinib plus capecitabine and trastuzumab at the San Antonio Breast Cancer Symposium in December, as well as updating everyone on our clinical and regulatory plans later this quarter."

THIRD QUARTER AND RECENT HIGHLIGHTS

Clinical Development

• HER2CLIMB, continues to be on track with enrollment of Phase 2 tucatinib (ONT-380) combination trial. This randomized, double-blind, placebo-controlled study is evaluating the safety and efficacy of tucatinib versus placebo in combination with capecitabine and trastuzumab in late stage HER2+ breast cancer patients, with and without brain metastases, who have previously been treated with a taxane, trastuzumab, pertuzumab and T-DM1. Tucatinib, which has Fast Track designation from the FDA in this setting, is expected to enroll approximately 180 patients at sites in the U.S., Canada and select countries in Western Europe. Previously reported results from the ongoing Phase 1b study of the tucatinib "Triplet" combination demonstrated promising systemic activity, a favorable safety profile and activity against brain metastases, which represents a significant unmet medical need.
  
  
• Data presented at ESMO 2016 show early evidence of activity of tucatinib combination therapy in patients with cutaneous HER2+ metastases. In a poster presentation, Dr. Alison Conlin, study author and Medical Oncologist, Providence Cancer Center, Portland, OR, presented data on eight patients with HER2+ metastases to the skin who received the maximum tolerated tucatinib dose in combination with capecitabine and/or trastuzumab from the Company's Phase 1b combination study. Patients had previously received a median of six lines of drug therapy. Responses observed in skin lesions in these patients included one complete response, four partial responses and three patients with stable disease, including one partial response of a patient receiving tucatinib and trastuzumab only.
  
  
• Continue to advance novel Chk1 cell cycle inhibitor with goal of conducting IND-enabling studies. Preclinical research has shown that select Cascadian Chk1 inhibitors display cellular potency in in vitro models against Chk1, are active against a diverse range of cancer cell lines, and demonstrate synergistic activity in combination with certain chemotherapeutic drugs.

Corporate Update

• Cascadian's board of directors has called a Special Stockholder Meeting to vote on a reverse split of the Company's common stock and a reduction of the authorized common stock. The objective is to make the stock accessible to a wider range of institutional investors, benefiting all stockholders, and ensure that the necessary financial structure is in place to execute product development and other necessary corporate initiatives. The stockholder vote on the proposal will be held on November 18, 2016. For details, see the proxy statement at www.sec.gov/edgar. 

THIRD QUARTER 2016 FINANCIAL HIGHLIGHTS

• Cash, cash equivalents and investments totaled $71.6 million as of September 30, 2016, compared to $56.4 million at December 31, 2015, an increase of $15.2 million, or 27.0%. The increase was primarily the result of net proceeds of $43.3 million from the Company's June 2016 financing offset by cash used to fund operations of $28.1 million.    
   
• Net loss attributable to common stockholders for the three months ended September 30, 2016 was $11.8 million, or $0.09 per basic and diluted share, compared with a net loss attributable to common stockholders of $4.6 million, or $0.05 per basic and diluted share, for the comparable period in 2015. The increase in net loss attributable to common stockholders for the quarter was primarily due to increases in research and development expenses of $2.2 million primarily due to greater activity related to the development of the Company's product candidates and increases in general and administrative expenses of $1.4 million primarily due to expenses related to the Company's Retention Payment Plan and higher professional fees associated with legal and regulatory compliance. The Company also recognized a non-cash $1.0 million deemed dividend due to the beneficial conversion feature on the Series D convertible preferred stock. In addition, the increase in net loss attributable to common stockholders was due to lower non-cash income from the change in the fair value of the Company's warrant liability, which was zero for the three months ended September 30, 2016 compared to $2.6 million for the three months ended September 30, 2015. The change in the fair value of warrant liability was due to the expiration of September 2010 warrants, which expired in October 2015.
   
• Net loss attributable to common stockholders for the nine months ended September 30, 2016 was $49.8 million, or $0.46 per basic and diluted share, compared with a net loss attributable to common stockholders of $23.5 million, or $0.24 per basic and diluted share, for the comparable period in 2015. The increase in net loss attributable to common stockholders for the nine months ended September 30, 2016 was primarily due to the intangible asset impairment charge of $19.7 million during the nine months ended September 30, 2016, which was the result of the mutual termination of the STC.UNM agreement. In addition, the increase in net loss attributable to common stockholders was due to increases in research and development expenses of $3.4 million primarily due to greater activity related to the development of the Company's product candidates, and increases in general and administrative expenses of $7.5 million primarily related to the retirement and separation agreement that Cascadian entered into with its former chief executive officer in January 2016, expenses related to the Company's Retention Payment Plan and higher professional fees associated with legal and regulatory compliance. 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 nine months ended September 30, 2016.
