SHANGHAI, China and CAMBRIDGE, Mass., Aug. 07, 2023 (GLOBE NEWSWIRE) -- Zai Lab Limited (NASDAQ:ZLAB, HKEX: 9688))) today announced financial results for the second quarter of 2023, along with recent product highlights and corporate updates.

"In the second quarter of 2023, we continued to successfully execute across our business. Our commercial products continued to deliver strong growth, with net product revenues growing 53% on a constant currency basis, and we made important progress for several late-stage and early development programs within our pipeline," said Dr. Samantha Du, Founder, Chairperson, and Chief Executive Officer of Zai Lab. "Most importantly, we gained NMPA approval of VYVGART, a first-in-class therapy that has the potential to significantly transform the lives of patients living with gMG in China, and we were able to achieve this monumental milestone on June 30th, which makes us eligible for NRDL listing in 2024. More recently, the positive data for efgartigimod in CIDP supports our confidence in its blockbuster potential across multiple indications."

"Looking ahead, Zai Lab has the potential for significant revenue growth and margin expansion over the next five years," said Josh Smiley, President and Chief Operating Officer of Zai Lab. "As highlighted at our 2023 Investor Day, we expect to have over 15 commercial-stage products, and at least one IND per year for global best-in-class/first-in-class assets, by the end of 2028. We expect our robust portfolio of assets to drive a revenue compound annual growth rate of over 50% from 2023 to 2028. As we launch new products and indications, we will continue to be prudent and capital efficient, prioritizing our R&D efforts and driving increased productivity across the organization. We expect that this discipline, along with our expected revenue growth, will allow us to reach corporate profitability by the end of 2025." Mr. Smiley concluded.

Recent Product Highlights and Corporate Updates

Zai Lab has established a differentiated portfolio and pipeline of assets, including 13 in late-stage development. We have had a number of exciting developments with respect to our products and product candidates, including the following updates since our last earnings release:

Commercial Products

We continued to increase sales for each of our commercial products in the second quarter of 2023, compared to the same period in 2022, driven by increased access for ZEJULA^®, QINLOCK^®, and NUZYRA^® as a result of their inclusion in the National Reimbursement Drug List (NRDL) and for Optune^® as a result of increased supplemental insurance plan coverage.

We also received the following regulatory approvals for our commercial products during the second quarter of 2023:

VYVGART^®: In June 2023, we received approval from the NMPA for the BLA for VYVGART (efgartigimod alfa injection), a first-in-class FcRn antagonist, as an add on standard therapy for the treatment of adult patients with gMG who are anti-acetylcholine receptor (AChR) antibody positive. We expect to commercially launch VYVGART in mainland China later this year.
Optune: In May 2023, the Taiwan Food and Drug Administration approved the Marketing Authorization Application (MAA) of Optune for the treatment of patients with glioblastoma multiforme (GBM).

Key Product Candidate Developments

We continued to advance our product candidates through our research and development and commercial operations, including the following developments with respect to our clinical trials and regulatory approvals:

Oncology

ZEJULA (niraparib, PARP): In July 2023, data from the Phase 3 PRIME study were published in JAMA Oncology, supporting the utility of ZEJULA as a maintenance therapy in a broad population of Chinese patients with newly diagnosed advanced ovarian cancer and demonstrating that an individual starting dose (ISD) of 200 or 300mg based on baseline bodyweight and platelet count can bring significant benefit to patients with an improved safety and tolerability profile of ZEJULA compared to a fixed 300mg starting dose. These data demonstrate that maintenance treatment with ZEJULA can significantly prolong progression-free survival versus placebo and can reduce the risk of disease progression or death by 55% with newly diagnosed advanced ovarian cancer.
Tumor Treating Fields (TTFields or Optune):
- Pancreatic Cancer: In July 2023, Zai Lab partner NovoCure Limited (NovoCure) announced a favorable Independent Data Monitoring Committee recommendation to continue the Phase 3 PANOVA-3 clinical trial of TTFields therapy in pancreatic cancer. Pre-specified interim analysis concluded that the fully enrolled PANOVA-3 clinical trial should proceed to final analysis as planned. Zai Lab participated in the Greater China portion of the study.
- NSCLC: In June 2023, Zai Lab and NovoCure announced the LUNAR Phase 3 clinical trial met the primary endpoint, demonstrating a statistically significant and clinically meaningful extension in overall survival for patients with metastatic NSCLC after platinum-based therapies. Zai Lab participated in the Greater China portion of the study.
  - Tumor Treating Fields therapy together with standard of care provided a statistically significant and clinically meaningful 3-month improvement in median overall survival versus standard of care with no added systemic toxicities; and
  - Tumor Treating Fields therapy together with immune checkpoint inhibitors resulted in an unprecedented 8-month improvement in median overall survival.
KRAZATI^® (adagrasib, KRAS^G12C):
- In July 2023, Zai Lab completed enrollment in China for the global Phase 3 KRYSTAL-10 trial of adagrasib in combination with cetuximab vs. chemotherapy in patients with previously treated advanced KRAS^G12C-mutated colorectal cancer.
- In June 2023, Zai Lab completed enrollment in China for the global Phase 2 KRYSTAL-7 trial of adagrasib in combination with pembrolizumab as first-line treatment for patients with advanced KRAS^G12C-mutated NSCLC.
Repotrectinib (ROS1/TRK): In June 2023, Zai Lab announced that the National Medical Products Administration (NMPA) in China has accepted its New Drug Application (NDA) for repotrectinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC, after granting priority review in May 2023. In May 2023, Zai Lab partner Bristol Myers Squibb (BMS) announced that the NDA for repotrectinib was accepted for priority review by the FDA for the same indication, with a Prescription Drug User Fee Act (PDUFA) date of November 27, 2023.
Bemarituzumab (FGFR2b): In July 2023, Zai Lab enrolled the first patient in the mainland China portion of the global Phase 3 FORTITUDE-101 study of bemarituzumab plus chemotherapy, versus placebo plus chemotherapy, in first-line gastric cancer with FGFR2b overexpression.

Autoimmune Disorders, Infectious Diseases and Neuroscience

VYVGART (efgartigimod, FcRn):
- gMG: In June 2023, argenx BV (argenx) announced that the FDA approved VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) injection for subcutaneous use in gMG. In July 2023, the NMPA accepted Zai Lab's BLA for efgartigimod alfa injection (subcutaneous injection) for the treatment of adult patients with gMG.
- CIDP: In July 2023, Zai Lab and argenx announced positive topline results from the global registrational ADHERE study evaluating VYVGART Hytrulo in adults with CIDP. Zai Lab participated in the Greater China portion of the study. Highlights of the results include:
  - Primary endpoint met (p=0.000039); VYVGART Hytrulo demonstrated a 61% reduction (HR: 0.39 95% CI: 0.25; 0.61) in the risk of relapse versus placebo;
  - 67% of patients in open-label Stage A demonstrated evidence of clinical improvement (ECI), indicating that IgG autoantibodies play a significant role in the underlying biology of CIDP; and
  - Safety and tolerability profile was consistent with previous clinical trials and the confirmed safety profile of VYVGART.
- Bullous pemphigoid (BP): In May 2023, Zai Lab enrolled the first patient in China in the global Phase 2/3 BALLAD study of SC efgartigimod in adult patients with BP.
XACDURO^® (SUL-DUR, Asia Pacific rights): In May 2023, Zai Lab partner Entasis Therapeutics, Inc. (Entasis), a wholly owned subsidiary of Innoviva, Inc., announced that the FDA approved XACDURO for the treatment of adults with hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible strains of Acinetobacter baumannii-calcoaceticus complex (Acinetobacter).
