Third Quarter 2018 Financial Results

Cash, Cash Equivalents, Restricted Cash and Short-Term Investments  were $2.10 billion as of September 30, 2018, compared to $1.40 billion as of June 30, 2018 and $837.52 million at December 31, 2017. The increase from the last quarter was primarily due to the net proceeds of $869.71 million from our global offering and listing on the Hong Kong Stock Exchange. Cash, cash equivalents, restricted cash and short-term investments as of September 30, 2018 include approximately $143.16 million held by our 95%-owned joint venture, BeiGene Biologics, to build a commercial biologics manufacturing facility under construction in Guangzhou, China, which includes restricted cash of $36.26 million related to BeiGene Biologics’ secured deposits.

Cash used by operations for the three months ended September 30, 2018 was $132.19 million, compared to cash generated by operations of $6.60 million for the same period in 2017. The increase in the use of cash was primarily attributable to the continued ramp-up in operating expenses in support of our ongoing and newly initiated late-stage pivotal clinical programs, preparation for regulatory filings and commercial launch of our late-stage drug candidates, and organizational growth, offset in part by revenue from product sales in China; in the prior period in 2017, cash generated by operations reflected receipt of the up-front payment from Celgene Corporation in connection with our license agreement for tislelizumab. Capital expenditures for the three months ended September 30, 2018 were $26.72 million, compared to $18.79 million for the same period in 2017. The increase was primarily attributable to the continued buildout of our manufacturing facility in Guangzhou.

Revenue  for the three months ended September 30, 2018 was $54.20 million, compared to $220.21 million in the same period in 2017. The decrease is primarily attributable to the upfront payment recognized in the prior year period under our collaboration agreement with Celgene for tislelizumab.

• Product revenue from sales of ABRAXANE ^® , REVLIMID ^® and VIDAZA ^® in China totaled $38.45 million for the third quarter of 2018, compared to $31.43 million for the three months ended June 30, 2018, and $8.82 million for the three months ended September 30, 2017 (which only included one month of product sales following the in-license from Celgene), respectively.
  
  
• Collaboration revenue totaled $15.76 million for the third quarter of 2018, compared to $21.38 million for the three months ended June 30, 2018, and $211.39 million for the three months ended September 30, 2017, respectively. The decrease, compared to the second quarter of 2018, is primarily due to lower research and development costs in the period on clinical trials that are being reimbursed by Celgene. The decrease, compared to the third quarter of 2017, is due primarily to the upfront revenue recognized in the third quarter of 2017 from the Celgene collaboration. 

Expenses for the three months ended September 30, 2018 were $205.30 million, compared to $105.31 million in the quarter ended September 30, 2017, consisting primarily of the following:

• Cost of sales for the three months ended September 30, 2018 were $8.71 million, compared to $1.94 million in the third quarter of 2017 (which only included one month of sales), an increase of 348.97 percent. Cost of sales relates to the cost of acquiring ABRAXANE ^® , REVLIMID ^® and VIDAZA ^® for distribution in China.  
  
  
• R&D Expenses for the three months ended September 30, 2018 were $147.59 million, compared to $87.66 million in the same period in 2017, an increase of 68.4%. The increase in R&D expenses was primarily attributable to increased spending on our ongoing and newly initiated late-stage pivotal clinical trials, preparation for regulatory filings and commercial launch of our late-stage drug candidates, manufacturing costs related to pre-commercial activities and supply, as well as increases in spending related to our preclinical-stage programs. The overall increase in R&D expenses was also attributable to increased R&D-related employee share-based compensation expense, which was $15.52 million for the three months ended September 30, 2018, compared to $10.38 million for the same period in 2017, due to increased headcount and a higher share price.
  
  
• SG&A Expenses for the three months ended September 30, 2018 were $48.82 million, compared to $15.64 million in the same period in 2017, an increase of 212.1%. The increase in SG&A expenses was primarily attributable to increased headcount, including the expansion of our commercial team to support the distribution of our existing commercial products in China and the potential launches of our late-stage drug candidates, higher professional service fees and costs to support our growing operations, and higher SG&A-related share-based compensation expense, which was $9.61 million for the three months ended September 30, 2018, compared to $2.95 million for the same period in 2017, due to increased headcount and a higher share price.
  
  
• Net Loss for the third quarter of 2018 was $144.03 million, or $2.53 per American Depositary Share (ADS), compared to net income of $117.39 million, or $2.79 per ADS in the same period in 2017. For the third quarter of 2018, net loss per ordinary share was $0.19, compared to net income of $0.21 in the same period in 2017.

BeiGene Initiates Global Head-to-Head Phase 3 Clinical Trial of Zanubrutinib in Patients with Relapsed/Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

CAMBRIDGE, Mass. and BEIJING, China, Nov. 07, 2018 (GLOBE NEWSWIRE) -- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced the first patient was dosed in a global Phase 3 clinical trial of its investigational BTK inhibitor zanubrutinib compared with ibrutinib in patients with relapsed/refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

“We continue to be encouraged by data on zanubrutinib in various B-cell malignancies and are excited to further expand the development program for zanubrutinib in CLL and SLL with this Phase 3 trial, which represents the second Phase 3 study directly comparing zanubrutinib to ibrutinib,” said Jane Huang, M.D., Chief Medical Officer, Hematology, at BeiGene.

The global Phase 3 open-label trial is expected to enroll approximately 400 patients with relapsed/refractory CLL or SLL across approximately 150 study centers in the U.S., China, Europe, Australia and New Zealand. Patients will be randomized in a one-to-one manner to either zanubrutinib (160 mg orally twice daily) or ibrutinib (420 mg orally once daily). The primary endpoint is overall response rate, as determined by independent central review. Key secondary endpoints include progression-free survival, duration of response, overall survival, patient-reported outcomes, and safety.

Zanubrutinib was recently granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with Waldenström macroglobulinemia (WM). New drug applications (NDAs) in China for zanubrutinib as a treatment for patients with mantle cell lymphoma (MCL) and for patients with relapsed/refractory CLL or SLL, have been accepted for review by the National Medical Products Administration of China (NMPA, formerly known as CFDA or CDA).

Zanubrutinib is being studied in a broad registration program. In addition to this newly initiated Phase 3 trial, it is also being evaluated in a fully enrolled, global Phase 3 clinical trial in patients with WM comparing zanubrutinib to ibrutinib, a global Phase 3 clinical trial in patients with previously untreated CLL, and a pivotal Phase 2 trial in combination with GAZYVA ^® (obinutuzumab) in patients with relapsed/refractory follicular lymphoma. In China, in addition to the MCL and CLL filings, BeiGene has completed enrollment in another pivotal Phase 2 clinical trial of zanubrutinib in patients with WM.

For more information about the trial, patients and physicians should email BeiGene at clinicaltrials@beigene.com.

About Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma 
Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are forms of non-Hodgkin lymphoma, a type of blood cancer, that arise from B lymphocytes. CLL and SLL are essentially the same disease, with the only difference being the location where the cancer primarily occurs. ¹ When most of the cancer cells are located in the bloodstream and the bone marrow, the disease is referred to as CLL, although the lymph nodes and spleen are often involved. When the cancer cells are located mostly in the lymph nodes, the disease is called SLL. ²

About Zanubrutinib
Zanubrutinib (BGB-3111) is an investigational small molecule inhibitor of Bruton’s tyrosine kinase (BTK) that is currently being evaluated in a broad pivotal clinical program globally and in China as a monotherapy and in combination with other therapies to treat various B-cell malignancies.
