August 9, 2018

CAMBRIDGE, Mass. and BEIJING, China, Aug. 09, 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 reported recent business highlights and financial results for the second quarter and first half of 2018.

“We continued to make excellent progress with encouraging new clinical data, including initial topline data from pivotal trials for our lead drug candidates, zanubrutinib and tislelizumab,” said John V. Oyler, Founder, Chief Executive Officer and Chairman of BeiGene. “We have also continued to expand our clinical programs and have now enrolled more than 3,000 patients worldwide in over 50 ongoing or planned clinical trials, including 17 pivotal or potentially registration-enabling trials of our drug candidates, with two new Phase 3 trials in China of tislelizumab in first-line non-small cell lung cancer having recently initiated. We are on track to submit new drug applications for zanubrutinib and tislelizumab in China this year and are planning to accelerate the U.S. NDA filing of zanubrutinib by seeking accelerated approval.”

“Our commercial organization in China is expanding its footprint to prepare for potential new product launches, and we have seen good growth of our commercial product revenue in China since the transition of these products to BeiGene since last September,” said Dr. Xiaobin Wu, General Manager of China and President of BeiGene, Ltd.

Second Quarter 2018 Financial Results

Cash, Cash Equivalents, Restricted Cash and Short-Term Investments were $1,401.22 million as of June 30, 2018, compared to $1,481.48 million as of March 31, 2018 and $837.52 million at December 31, 2017. Cash, cash equivalents, restricted cash and short-term investments as of June 30, 2018 include approximately $145.28 million held by our 95%-owned joint venture, BeiGene Biologics, to build a commercial biologics manufacturing facility under construction in Guangzhou, China, and restricted cash of $31.59 million related to BeiGene Biologics’ secured deposits. In the quarter, BeiGene Biologics received $42.32 million in proceeds from a new long-term loan with China Construction Bank for the continued construction of the manufacturing facility.

Cash used by operations for the three months ended June 30, 2018 was $117.14 million, compared to $51.89 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. Capital expenditures for the three months ended June 30, 2018 were $10.61 million, compared to $13.62 million for the same period in 2017. The decrease was primarily attributable to the purchase in the prior year period of the land use right in Guangzhou.

Revenue for the three months ended June 30, 2018 were $52.80 million, compared to nil in the same period in 2017, primarily attributable to product and collaboration revenue under our collaboration with Celgene.

-- Product revenue from sales of ABRAXANE®, REVLIMID® and VIDAZA® in China totaled $31.43 million for the second quarter of 2018. -- Collaboration revenue totaled $21.38 million for the second quarter of 2018, reflecting $18.18 million of research and development reimbursement revenue from Celgene, $1.70 million of research and development service revenue from deferred recognition of upfront fees, and $1.50 million of milestone revenue under the collaboration agreement for pamiparib with Merck KGaA, Darmstadt, Germany.

Expenses for the three months ended June 30, 2018 were $215.85 million, compared to $58.02 million in the same period in 2017, consisting primarily of the following:

-- Cost of salesfor the three months ended June 30, 2018 were $6.26 million, compared to nil in the second quarter of 2017. 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 June 30, 2018 were $164.25 million, compared to $47.25 million in the same period in 2017. 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 compensation expense, which was $10.72 million for the three months ended June 30, 2018, compared to $4.75 million for the same period in 2017, due to increased headcount and a higher share price. -- SG&A Expensesfor the three months ended June 30, 2018 were $45.16 million, compared to $10.78 million in the same period in 2017. 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-associated share-based compensation expense which was $7.92 million for the three months ended June 30, 2018, compared to $2.33 million for the same period in 2017, due to increased headcount and a higher share price. -- Net Lossfor the second quarter of 2018 was $156.89 million, or $2.92 per American Depositary Share (ADS), compared to a net loss of $60.55 million, or $1.52 per ADS in the same period in 2017. For the second quarter of 2018, net loss per ordinary share was $0.22, compared to $0.12 in the same period in 2017.
