Zai Lab Announces First Quarter 2021 Financial Results

Monday, 10. May 2021 13:32

SHANGHAI and SAN FRANCISCO, May 10, 2021 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, today announced financial results for the first quarter of 2021, along with recent product highlights and corporate updates.

“Zai Lab continued to execute well in all aspects of the business during the first quarter,” said Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab. “We entered into several strategic collaborations to further strengthen our gastric and lung cancer disease strongholds; significantly bolstered our autoimmune franchise with an exclusive agreement with argenx for efgartigimod, a pipeline-in-a-product opportunity; advanced numerous clinical programs toward key data readouts; gained approval of QINLOCK by the National Medical Products Administration (NMPA), our third innovative oncology product approval in the last 15 months in China and the first commercial product in what we expect to become a world-class gastric cancer franchise; and generated solid revenue growth, in part from increased volume of ZEJULA driven by its recent inclusion on the National Reimbursement Drug List (NRDL). In addition, we recently received encouraging news on several key assets from our partners. The Biologics License Application (BLA) filing of efgartigimod in generalized myasthenia gravis (gMG) was accepted by the U.S. Food and Drug Administration (FDA). The Phase 3 pivotal LUNAR trial of Tumor Treating Fields in non-small cell lung cancer (NSCLC) was recommended to continue with reduced sample size based on an accelerated interim analysis. Bemarituzumab was granted Breakthrough Therapy Designation by the FDA as first-line treatment for gastric cancer patients who overexpress FGFR2b.

“With the completion of our recent global public offering with gross proceeds of nearly $860 million, we significantly strengthened our capital position. This new capital will allow us to accelerate our growth by entering into additional strategic partnerships, advancing our clinical development pipeline, and scaling our commercial and R&D organizations to drive strong revenue growth and enhance our global pipeline.

“We remain on target to advance all stages of our product pipeline throughout 2021. We continue to expect approval of Nuzyra for community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI) by the NMPA. We plan to file margetuximab for Her2-positive breast cancer, Tumor Treating Fields for mesothelioma and ZEJULA for late-line ovarian cancer in China. We are engaging with the NMPA on the regulatory filing strategy for efgartigimod in gMG in China. And we anticipate numerous data readouts, including for Tumor Treating Fields in liver cancer and ovarian cancer, for QINLOCK in second-line GIST, for margetuximab in gastric cancer, for CLN-081 in NSCLC and for TPX-0022 in NSCLC and gastric cancer.

“In our mission to address serious unmet medical needs for patients in China and around the world, we believe that we have built a sustainable platform that we can leverage,” Dr. Du concluded. “Our team continues to deliver on our aggressive growth objectives. I believe that the future of Zai Lab has never been brighter.”

Recent Product Highlights and Anticipated Milestones


ZEJULA® (niraparib)

ZEJULA is an oral, once-daily small-molecule poly ADP-ribose polymerase (PARP) 1/2 inhibitor. It is the only PARP inhibitor approved in the United States, the European Union and mainland China (hereinafter, “China”) as a monotherapy for patients with advanced ovarian cancer, regardless of their biomarker status.

Anticipated 2021 Zai Milestones

  • Complete enrollment of the Phase 1b study of ZEJULA in combination with tebotelimab (PD-1 x LAG-3) in gastric cancer.

  • Announce topline results of the Phase 3 PRIME study of ZEJULA in patients with first-line ovarian cancer in China in the second half.

Tumor Treating Fields

Tumor Treating Fields is a cancer therapy that uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and potentially causing cancer cell death.

Recent Product Highlights

  • In April 2021, Zai Lab partner Novocure announced an update regarding its Phase 3 pivotal LUNAR trial in stage 4 NSCLC following failure on platinum-based chemotherapy. After a review by an independent data monitoring committee (DMC), Novocure was informed by the committee that the pre-specified interim analysis for the LUNAR trial had been accelerated given the length of accrual and the number of events observed. The DMC concluded that it is likely unnecessary and possibly unethical for patients randomized to the control arm to continue accrual to 534 patients with 18 months follow-up. The DMC further recommended a reduced sample size of approximately 276 patients with 12 months follow-up. Novocure has filed an IDE supplement with the FDA and is awaiting the agency’s response.

First-Quarter 2021 Financial Results

  • For the three months ended March 31, 2021, net product revenues were $20.1 million, compared to $8.2 million for the same period in 2020. Revenues for the period were comprised of $12.6 million for ZEJULA, compared to $6.3 million for the same period in 2020; and $7.1 million for Optune, compared to $1.9 million for the same period in 2020.

  • Research and Development (R&D) expenses were $203.9 million for the three months ended March 31, 2021, compared to $33.7 million for the same period in 2020. The increase in R&D expenses was primarily attributable to a $62.3 million upfront payment in Zai Lab equity (fair value of the shares on the closing date of the agreement due to certain restrictions) and a $75 million development cost-sharing payment to argenx; a $25 million upfront payment to Turning Point; expenses related to ongoing and newly initiated late-stage clinical trials; and payroll and payroll-related expenses from increased R&D headcount.

  • Selling, General and Administrative expenses (SG&A) were $35.8 million for three months ended March 31, 2021, compared to $18.7 million for the same period in 2020. The increase was primarily due to payroll and payroll-related expenses from increased commercial headcount and related costs, as Zai Lab continued to expand its commercial operations in China.

  • For the three months ended March 31, 2021, Zai Lab reported a net loss of $232.9 million, or a loss per share attributable to common stockholders of $2.64, compared to a net loss of $48.0 million, or a loss per share attributable to common stockholders of $0.66, for the same period in 2020. The increase in the net loss was primarily attributable to payments related to new business development activities with argenx and Turning Point recorded in R&D expenses.
  • As of March 31, 2021, cash and cash equivalents, short-term investments and restricted cash totaled $1,014.2 million compared to $1,187.5 million as of December 31, 2020. In addition, in April 2021, Zai Lab announced the closing of a global follow-on offering. The expected total proceeds to Zai Lab, including both the American depositary shares offering and the ordinary shares offering, net of underwriting fees and other offering expenses, are approximately $818.1 million.
