SHANGHAI and CAMBRIDGE, Mass., May 09, 2023 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced financial results for the first quarter of 2023, along with recent product highlights and corporate updates.

“Our first quarter results and progress continue to demonstrate Zai Lab’s potential global best-in-class portfolio and track record of execution, despite challenges from China’s re-opening at the beginning of the year,” said Dr. Samantha Du, Founder, Chairperson and Chief Executive Officer of Zai Lab. “The positive topline readout from the Phase 3 EMERGENT-3 trial of KarXT in schizophrenia and the positive interim analysis from the innovaTV 207 Phase 2 study of TIVDAK in head and neck cancer further support our belief that these are important treatment options for patients in China and globally. We are also very excited about the U.S. Food and Drug Administration (FDA) Advisory Committee’s unanimous recommendation in support of approval for sulbactam-durlobactam, the first pathogen-targeted therapy for patients with serious and life-threatening infections caused by Acinetobacter.”

“Recently, we expanded our lung cancer franchise and enriched our global oncology pipeline with a next generation DLL3 ADC program, ZL-1310,” said Dr. Du. “This global ADC program demonstrates our continued focus on the ADC space. This product complements our lung cancer franchise, and we will leverage our strong capabilities to develop ZL-1310, and look forward to seeing results in patients.”

“I look forward to leading Zai into its next transformational stage of growth, productivity, and global opportunities. To better support me and help meet the strategic and operational needs of our business during this next stage of growth, we are happy to announce that we have promoted Josh Smiley to President and Chief Operating Officer. Josh’s rich experience and strategic vision will help us further grow as a leading global biopharmaceutical company and deliver on our mission to improve human health and on our corporate strategic goals for driving innovation in China and beyond,” Dr. Du concluded.

“I am very excited about what is in store for us in the next few years that positions Zai Lab to be a leader in biopharma innovation,” said Josh Smiley. “We are pleased with the overall environment this year in China for companies like Zai Lab with innovative therapies that meet significant unmet medical needs. We expect strong growth momentum to continue throughout the remainder of this year.”

“With respect to our 2023 strategic priorities, we have made progress toward the Biologics License Application (BLA) approval of efgartigimod for generalized myasthenia gravis (gMG) and the BLA submission for subcutaneous (SC) efgartigimod for gMG in China, initiation of a bridging study for KarXT in schizophrenia in Greater China, initiation of a registrational study for bemarituzumab in first-line gastric cancer in Greater China and a full data readout of the Tumor Treating Fields LUNAR study in non-small cell lung cancer. We are also advancing our proprietary pipeline with global rights, including initiating a global Phase 1 study for ZL-1218 (CCR8) and moving ZL-1102 (IL-17 Humabody^®) into full global development,” Mr. Smiley concluded.

Recent Product Highlights and Corporate Updates

Zai Lab has established a differentiated portfolio and pipeline of 22 potentially global best-in-class and/or first-in-class therapies, including 13 in late-stage development. During the first quarter of 2023, we had a number of exciting developments with respect to our products and product candidates, including the following:

Commercial Products

We continued to increase access to our commercial products, including through increased sales for ZEJULA^® (niraparib), new NRDL listings for QINLOCK^® (ripretinib) and NUZYRA^® (omadacycline), and increased supplemental insurance listings for Optune:

• Sales growth for ZEJULA: Net product revenue for ZEJULA continued to increase in the first quarter of 2023, growing 44.2% compared to the first quarter of 2022. We believe ZEJULA remains on track to become the leader in its asset class for ovarian cancer in China starting this year.
  
  
• The National Reimbursement Drug List (NRDL) implementation: The updated NRDL released by China’s National Healthcare Security Administration (NHSA) officially took effect on March 1, 2023. It has been updated to include both QINLOCK and NUZYRA.
  
  
• Supplemental insurance plan coverage (as of March 31, 2023): Optune was listed in 96 regional customized commercial health insurance plans guided by provincial or municipal governments (or supplemental insurance plans), up from 87 as of December 31, 2022 and 37 as of March 31, 2021.

First-Quarter 2023 Financial Results

• Product revenues were $62.8 million for the first quarter of 2023, compared to $46.1 million for the same period in 2022, representing a 36.2% y-o-y growth. Product revenue for the first quarter of 2023 was $42.7 million for ZEJULA, compared to $29.6 million for the same period in 2022, representing a 44.2% y-o-y growth; $13.3 million for Optune, compared to $12.8 million for the same period in 2022, representing a 4.3% y-o-y growth; $1.3 million for QINLOCK, compared to $3.0 million for the same period in 2022; and $5.5 million for NUZYRA, compared to $0.7 million for the same period in 2022.
  
  
  • Note that product revenue for the first quarter of 2023 included a negative $3.9 million adjustment to compensate distributors for sales of QINLOCK and NUZYRA at prices prior to the price reductions made in connection with their addition to the NRDL in the first quarter of 2023. Such sales rebates to distributors on previously purchased products are customary in our industry to compensate those distributors for the new NRDL selling price.
    
    
• Research and Development (R&D) expenses were $48.5 million for the first quarter of 2023, compared to $53.9 million for the same period in 2022. The decrease in R&D expenses was primarily due to cost-sharing compensation from collaboration partners related to our clinical trials, partially offset by higher payroll and payroll-related expenses from increased R&D headcount.
  
  
• Selling, General and Administrative expenses were $62.5 million for the first quarter of 2023, compared to $57.0 million for the same period in 2022. The increase was primarily due to higher professional service fees and in connection with sales of our products in mainland China and Hong Kong, and higher payroll and payroll-related expenses from increased commercial headcount.
  
  
• Net loss was $49.1 million for the first quarter of 2023, or a loss per share attributable to common stockholders of $0.05, compared to a net loss of $82.4 million for the same period in 2022, or a loss per share attributable to common stockholders of $0.09. The decrease in net loss was primarily due to product revenue growing faster than operating expenses, and an increase in non-operating income, including interest income and foreign currency gain.
  
  
• Cash and cash equivalents, short-term investments and restricted cash totaled $931.4 million as of March 31, 2023, compared to $1,009.3 million as of December 31, 2022.
