Zai Lab Announces Full-Year 2023
Financial Results and Recent Corporate Updates
Total product revenue of $266.7 million for Full-Year 2023, representing 25% y-o-y growth; 31% y-o-y growth at constant exchange rate (CER)
VYVGART® (efgartigimod alfa injection) was launched in September 2023 in China and we estimate that nearly 1,000 patients were treated through the fourth quarter before its listing on China’s National Reimbursement Drug List (NRDL)
We estimate that nearly 1,000 new patients were treated with VYVGART in January 2024 alone; expect VYVGART product sales to exceed $70.0 million in 2024
Regulatory reviews ongoing for sulbactam-durlobactam, efgartigimod SC and repotrectinib; up to four new regulatory submissions expected in 2024
Strong balance sheet with a cash position of $807.6 million as of December 31, 2023, compared to $1.0 billion as of December 31, 2022
Company to host conference call and webcast on February 28, 2024, at 8:00 a.m. ET (9:00 p.m. HKT)
SHANGHAI, China and CAMBRIDGE, Mass., February 27, 2024 -- Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced financial results for full-year 2023, along with recent product highlights and corporate updates.
“We made excellent progress on several key strategic priorities in 2023, notably the launch of VYVGART in China for generalized myasthenia gravis (gMG) in September and the drug’s successful inclusion on China’s NRDL for this indication effective January 1, 2024,” said Dr. Samantha Du, Founder, Chairperson, and Chief Executive Officer of Zai Lab. “The launch is off to an impressive start with more patients treated with VYVGART in January than the last four months of 2023 combined, fueled by high physician adoption and increased patient access as hospitals add VYVGART to formularies. Looking ahead, we expect strong commercial performance across our portfolio this year, and are preparing for three new potential launches in 2024. We are also excited by the progress of our late-stage pipeline and our growing global early-stage development efforts. We are on track to achieve the objectives outlined in our five-year strategic plan and to position Zai Lab as a high-growth, profitable and innovative biotech company.”
“We are focused on achieving three corporate objectives,” said Josh Smiley, President and Chief Operating Officer of Zai Lab. “First, we seek to accelerate top-line growth supported by multiple launches of new products and indications over the next two to three years. Second, we aim to reach corporate profitability by the end of 2025 through revenue growth and continued focus on efficiency and productivity. Third, we are committed to building a global portfolio through our internal discovery activities and strategic business development. These corporate objectives capture our vision for Zai Lab, where we lead with innovation, grow with purpose, and deliver on our mission of improving patient lives globally,” Mr. Smiley concluded.
Full-Year 2023 Financial Results
Product revenue was $266.7 million in 2023, compared to $212.7 million in 2022, representing 25% y-o-y growth and 31% y-o-y growth at CER. This increase was primarily driven by increased sales volumes, the launch of VYVGART, and decreased negative effects from the COVID-19 pandemic, partially offset by an increase in sales rebates to distributors and the effects on hospital and physician practices from the recent industry-wide anti-corruption enforcement efforts in China in the second half of 2023.
Sales rebates to distributors resulting from price reductions in connection with NRDL listings were $13.0 million in 2023, up from $5.3 million in 2022, driven by an increased number of new and renewed NRDL listings.
1


Key Highlights by Commercial Products
ZEJULA®
$168.8 million in 2023, which increased 16% y-o-y from $145.2 million in 2022.
The increase was driven by increased hospital sales in first-line ovarian cancer and duration of treatment prolongment, partially offset by sales rebates in connection with the renewal in the NRDL.
ZEJULA continues to be the leading PARP inhibitor in hospital sales for ovarian cancer in China, in its third year on the NRDL.
ZEJULA’s NRDL listing was renewed for the maintenance treatment of adult patients with first-line and recurrent ovarian cancer, effective January 1, 2024.
VYVGART®
$10.0 million in 2023, compared to nil in 2022.
We successfully launched VYVGART for the treatment of adult patients with gMG, who are anti-acetylcholine receptor (AChR) antibody positive, in September 2023.
We estimate that nearly 1,000 patients were treated from launch through the fourth quarter of 2023.
VYVGART was added to the NRDL for the treatment of gMG, effective January 1, 2024.
We estimate that nearly 1,000 new patients were treated in January 2024 alone driven by positive physician and patient reception as well as increased patient access as VYVGART is added to hospital formularies.
We are expecting more than $70.0 million in VYVGART revenue in 2024.
OPTUNE®
$47.0 million in 2023, which was relatively flat compared to $47.3 million in 2022.
Continued growth in supplemental insurance coverage was offset by the effects of industry-wide anti-corruption efforts.
QINLOCK®
$19.2 million in 2023, which increased 29% y-o-y from $15.0 million in 2022.
Growth was supported by its inclusion in the NRDL in the first quarter of 2023 for the fourth-line treatment of advanced gastrointestinal stromal tumors (GIST), partially offset by sales rebates in connection with the NRDL listing.
NUZYRA®
$21.7 million in 2023, which increased by 316% y-o-y from $5.2 million in 2022.
Growth was driven by the initial inclusion of NUZYRA (IV formulation) for the treatment of adults with community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI) in the NRDL in the first quarter of 2023.
The oral formulation of NUZYRA was added to the NRDL for these indications, effective January 1, 2024, which we expect to further increase patient access.
Research and Development (R&D) expenses were $265.9 million for 2023, compared to $286.4 million for 2022. This decrease was primarily due to decreased upfront and milestone payments for our license and collaboration agreements, partially offset by an increase in personnel compensation and related costs.
Selling, General and Administrative expenses were $281.6 million for 2023, compared to $259.0 million for 2022. This increase was primarily due to higher general selling expenses related to commercial operations to support the launch of VYVGART, partially offset by a decrease in professional services fees.
Net loss was $334.6 million for 2023, or a loss per ordinary share attributable to common stockholders of $0.35 (or loss per American Deposit Share (“ADS”) of $3.46), compared to a net loss of $443.3 million for 2022, or a loss per ordinary share of $0.46 (or loss per ADS of $4.63). The decrease in net loss was primarily due to product revenue growing faster than net operating expenses, increased interest income, and decreased foreign currency loss.
Cash and cash equivalents, short-term investments and restricted cash totaled $807.6 million as of December 31, 2023, compared to $1.0 billion as of December 31, 2022.

Oncology Pipeline
Tumor Treating Fields:
In January 2024, Zai Lab partner Novocure announced that the U.S. Food and Drug Administration (FDA) had accepted for filing its Premarket Approval (PMA) application seeking approval for the use of Tumor Treating Fields therapy together with standard systemic therapies for the treatment of NSCLC, following progression on or after platinum-based therapy. We are preparing a similar submission for this indication, with a goal to submit a Marketing Authorization Application (MAA) to the National Medical Products Administration (NMPA) in 2024.
3



Repotrectinib (ROS1/TRK):
In February 2024, Zai Lab partner Bristol-Myers Squibb (BMS) announced that, based on the results of the TRIDENT-1 trial, the FDA has accepted its supplemental NDA (sNDA) for repotrectinib for the treatment of adult and pediatric patients 12 years of age and older with solid tumors that have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion, and are locally advanced or metastatic or where surgical resection is likely to result in severe morbidity. The application was granted priority review status, with a Prescription Drug User Fee Act (PDUFA) goal date of June 15, 2024.
In November 2023, BMS announced that, based on results from the TRIDENT-1 trial, the FDA approved repotrectinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC. The New Drug Application (NDA) that Zai Lab submitted to the NMPA for this indication is under priority review.
Adagrasib (KRASG12C)
In February 2024, Zai Lab partner BMS announced that, based on the results of the KRYSTAL-1 trial, the FDA has accepted its sNDA for adagrasib in combination with cetuximab for the treatment of patients with previously treated KRASG12C-mutated locally advanced or metastatic colorectal cancer (CRC). The application was granted priority review status, with a PDUFA goal date of June 21, 2024. We are participating in the global confirmatory Phase 3 KRYSTAL-10 study in second-line KRASG12C-mutated CRC in Greater China.
Bemarituzumab (FGFR2b):
Zai Lab has joined the global Phase 3 FORTITUDE-102 study of bemarituzumab in combination with nivolumab and chemotherapy in first-line gastric or GEJ cancer in Greater China. We expect the first patient in Greater China to be treated in the first quarter of 2024.

The application has been granted a PDUFA goal date of September 26, 2024. We continue to enroll patients in the registrational bridging study in mainland China, and we expect to complete the study this year.
In November 2023, Karuna announced positive results from its Phase 1b open-label, eight-week inpatient trial evaluating the effect of xanomeline-trospium on 24-hour ambulatory blood pressure in adults with schizophrenia demonstrating that xanomeline-trospium was not associated with increases in blood pressure.
