SHANGHAI and SAN FRANCISCO and CAMBRIDGE, Mass., Aug. 09, 2022 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688), a patient-focused, innovative, commercial-stage, global biopharmaceutical company, today announced financial results for the second quarter of 2022, along with recent product highlights and corporate updates.

“We executed well in the second quarter and delivered strong results,” said Dr. Samantha Du, Founder, Chairperson and CEO, of Zai Lab. “Despite the challenging operating environment, Zai has continued to achieve all of our corporate priorities, including the BLA acceptance for efgartigimod by China’s NMPA. With the positive topline readout from the Phase 3 EMERGENT-2 trial in schizophrenia earlier this week, we believe KarXT could be a very important treatment option as the first new class of medicine in over half a century for the many patients suffering from schizophrenia in China and globally. I’m also excited that our pipeline continues to mature and demonstrate first and best-in-class potential. In addition, there were positive data readouts for adagrasib, CLN-081, repotrectinib, efgartigimod, ZEJULA and Tumor Treating Fields in the second quarter. Importantly, our commercial operations remain resilient in the face of the ongoing pandemic situation in certain regions in China. For the remainder of the year, we are on track to deliver our remaining 2022 corporate priorities, including an NDA submission to the NMPA for sulbactam-durlobactam, advancing ZL-1102 (anti-IL-17A Humabody®) into full global development, as well as seeking NRDL inclusion for QINLOCK and NUZYRA. We are also very pleased to welcome Josh Smiley as our COO at this exciting time given his operational expertise, global experience, and deep understanding of Zai Lab and our industry.”

“I am thrilled to be joining Zai Lab at such a pivotal time in the company’s history,” said Josh Smiley, COO of Zai Lab. “Zai is working toward becoming a leading global biotech company, leveraging its commercial success in Asia and its development of global products. The advancement of Zai’s proprietary research pipeline and the diversification of its portfolio beyond its traditional strength in oncology present tremendous opportunities. I am looking forward to working with the great team and helping scale the company both in China and in the United States.”

Corporate Updates

• In June 2022, Zai Lab completed the voluntary conversion of its secondary listing status in Hong Kong to a primary listing on the Main Board of The Hong Kong Stock Exchange. Zai Lab is now a dual-primary listed company, with its ordinary shares traded on the Hong Kong Stock Exchange and its American Depositary Shares traded on the Nasdaq Global Market.

• In June and July 2022, Zai Lab’s ordinary shares have been included in the Shenzhen- and Shanghai-Hong Kong Stock Connect programs, respectively. These Stock Connect programs permit eligible investors in mainland China to invest in the Company.

• Zai Lab engaged KPMG LLP as the company’s auditor, effective May 31, 2022. The engagement of this U.S. auditor, which is subject to full inspection and review by the Public Company Accounting Oversight Board, was a natural progression of Zai Lab’s global growth. With a principal executive office in Cambridge, Massachusetts and significant operations and a majority of the company’s Board and executives in the United States, Zai Lab may be audited by KPMG in the United States. As a result, we believe that we will be in compliance with the requirements of the Holding Foreign Companies Accountable Act (HFCAA) beginning with our annual report for the fiscal year ending December 31, 2022, and that we will not be conclusively identified under the HFCAA in 2023 or going forward. The company expects, therefore, its Nasdaq listing to continue uninterrupted. Our full statement on the appointment of KPMG can be found on the Investors section of the Zai Lab website.

• Zai Lab has continued to enhance its corporate governance and leadership team. In July 2022, the Board of Directors appointed John Diekman to be Lead Independent Director. In light of the additional responsibilities of the Lead Independent Director, Mr. Diekman stepped down as Chair of the Audit Committee, although he will continue to serve as a member of the Audit Committee, and Scott Morrison has been appointed Chair of the Audit Committee. Also, Josh Smiley joined the Company as Chief Operating Officer, effective August 1. He will report directly to the Chief Executive Officer and will be a key member of the executive committee.

• As of June 30, 2022, Zai Lab employed 2,063 full-time employees, including 861 and 968 employees engaged in R&D and commercial activities, respectively.
  

Second-Quarter 2022 Financial Results

• For the three months ended June 30, 2022, total revenues were $48.2 million, compared to $36.9 million for the same period in 2021. Product revenues for the period were $34.1 million for ZEJULA, compared to $23.4 million for the same period in 2021; $11.6 million for Optune, compared to $9.5 million for the same period in 2021; $0.6 million for QINLOCK, compared to $4.0 million for the same period in 2021, and $1.3 million for NUZYRA, compared to nil for the same period in 2021.
  
  
  • QINLOCK and NUZYRA are scheduled to enter negotiations with the National Healthcare Security Administration (NHSA) regarding potential inclusion in the NRDL, and in June 2022, the Company lowered the selling price for these products. Accordingly, the Company accrued $2.9 million of sales rebates as compensation to distributors for those products previously sold at the price prior to the reduction during the three months ended June 30, 2022.

• Research and Development (R&D) expenses were $66.1 million for the three months ended June 30, 2022, compared to $142.2 million for the same period in 2021. The decrease in R&D expenses was primarily due to no upfront payment for new licensing agreements, partially offset by increased expenses related to ongoing and newly initiated clinical trials and higher payroll and payroll-related expenses from increased R&D headcount. Excluding upfront payments for new licensing agreements, core R&D expenses were $51.7 million for the same period in 2021.
  
  
• Selling, General and Administrative (SG&A) expenses were $63.4 million for the three months ended June 30, 2022, compared to $54.4 million for the same period in 2021. The increase was primarily due to payroll and payroll-related expenses from increased commercial and general and administrative headcount, as Zai Lab continued to expand and invest in its commercial operations in China in anticipation of strong topline growth over the next few years.

• Net loss was $137.9 million for the three months ended June 30, 2022, compared to $163.3 million for the same period in 2021. The decrease in net loss was primarily due to no upfront payments for new licensing agreements partially offset by an increase in foreign exchange loss of $42.2 million, which is a non-cash adjustment. Net loss per ordinary share during the three months ended June 30, 2022 was $0.14, compared to $0.18 for the same period in 2021. Net loss per ADS during the three months ended June 30, 2022 was $1.44, compared to $1.76 for the same period in 2021.

• As of June 30, 2022, cash and cash equivalents, short-term investments, and restricted cash totaled $1,256.9 million, compared to $1,313.0 million as of March 31, 2022.
