SHANGHAI and SAN FRANCISCO, Aug. 13, 2020 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB), an innovative commercial-stage biopharmaceutical company, today announced financial results for the six months ended June 30, 2020 and corporate updates.

“This year we have continued to build Zai Lab’s leadership through strong execution. Highlights include two successful commercial launches in China, NMPA approval for Optune, two highly strategic collaboration deals, three NDAs accepted with priority review, 15 clinical trial authorizations approved and eight trial initiations across our innovative pipeline which now includes 14 clinical stage assets,” said Dr. Samantha Du, Founder, Chairwoman and Chief Executive Officer of Zai Lab. “We were able to overcome headwinds brought on by the COVID-19 pandemic, launching both ZEJULA and Optune in under six weeks from regulatory approval and gaining immediate support from the medical, patient and payor communities. Our clinical pipeline continues to strengthen with the addition of two key late-stage assets, REGN1979 and Repotrectinib. With our broad and differentiated pipeline, we remain confident that Zai Lab can become a leading global biopharma company, leveraging our capabilities and network to drive the next wave of innovations with transformative impact on patients with significant unmet medical needs. Over the next three years, we expect to have a steady stream of approvals and commercial product launches in Greater China across multiple therapeutic areas, establish transformative partnerships, expand our global footprint, and advance our internally discovered global pipeline into the pivotal stage.”

First-Half 2020 Financial Results

  • For the six months ended June 30, 2020, net product revenues were $19.2 million, compared to $3.4 million for the same period in 2019. Revenues for the period were comprised of $13.8 million in sales of ZEJULA and $5.4 million in sales of Optune, respectively. Launched in January 2020, ZEJULA’s revenue in mainland China was the main driver for the first half of 2020 given Optune was commercially available at the end of June.
  • R&D expenses were $102.0 million for the six months ended June 30, 2020, compared to $58.9 million for the same period in 2019. The increase in R&D expenses were primarily attributable to increased fees in connection with the upfront and milestone payments for new licensing and strategic collaboration agreements, ongoing and newly initiated late-stage clinical trials, payroll and payroll-related expenses from increased R&D headcount and expansion of research efforts to support internal development programs.
  • Selling, General & Administrative expenses were $42.5 million for the six months ended June 30, 2020 compared to $29.5 million for the same period in 2019. The increase was primarily due to payroll and payroll-related expenses from increased commercial headcount and related costs as Zai Lab expanded its commercial operations in China.
  • For the six months ended June 30, 2020, Zai Lab reported a net loss of $128.6 million, or a net loss per share attributable to common stockholders of $1.74, compared to a net loss of $83.3 million, or net loss per share attributable to common stockholders of $1.37, for the same period in 2019.
