Description

In August 2018, Zai Lab announced the early completion of an open-label study to evaluate the pharmacokinetic (PK) profile of ZL-2306 (niraparib) made in China in Chinese ovarian cancer patients. The study demonstrated a comparable PK profile of Chinese patients who were administered ZL-2306 to the PK profile of patients evaluated in Tesaro’s clinical trials using product manufactured outside of China. These results support the regulatory review of ZL-2306 (niraparib) in China.

In August 2018, Zai Lab enrolled the first patient in its Phase III registration trial of ZL-2306 (niraparib) as a first-line maintenance therapy in small cell lung cancer (SCLC) in China. This will be the first clinical trial of ZL-2306 (niraparib) in this type of cancer.

In June 2018, Zai Lab dosed the first patient in its Phase III China registration trial of ZL-2306 (niraparib) for first-line maintenance therapy of patients with platinum-responsive ovarian cancer.

In May 2018, Zai Lab received clinical trial application (CTA) approval from China’s National Drug Administration (CNDA) to enroll Chinese patients in the Phase I/III FIGHT (FGFR2b Inhibition in Gastric and Gastroesophageal Junction Cancer Treatment) global registrational trial, evaluating FPA144 (bemarituzumab) in combination with a modified FOLFOX chemotherapy regimen. Zai Lab received CTA approval three months ahead of schedule.

In April 2018, Zai Lab’s bridging approach leveraging the Phase III ZL-2401 (omadacycline) studies conducted abroad was accepted by China’s Center for Drug Evaluation (CDE). An agreement was reached with CDE for the Company’s proposal to conduct a truncated clinical program for approval in China. Zai Lab obtained CTA approval from CNDA within three and a half months of submitting its application and is ready to implement the requested China studies in the fourth quarter of 2018.

In August 2018, results of a Phase II study evaluating ZL-3101 (Fugan), a natural product in patients with mild to moderate atopic dermatitis, received four months ahead of schedule, showed ZL-3101 was safe and well-tolerated, but did not show signs of efficacy over placebo. The Company elected to discontinue further development of ZL-3101 (Fugan) based on these findings and shift related resources to other programs.

In August 2018, Zai Lab appointed Yong-Jiang Hei, M.D., Ph.D., as its CMO, Oncology. Dr. Hei is a seasoned industry expert with over 20 years of experience in clinical development in oncology and will support the strategic development and expansion of the Company’s growing oncology clinical pipeline. Most notably, he served at Amgen, Inc. for approximately 10 years in multiple roles of increasing responsibility in oncology global development. Dr. Qi Liu will transition to an advisory role.

In August 2018, Zai Lab appointed Kai-Xian Chen, Ph.D., to its Board of Directors. Professor Chen is a globally recognized scientist and widely regarded as a pioneer in the field of interdisciplinary healthcare research. In connection with Professor Chen’s appointment, Marietta Wu, Ph.D. retired from the Board of Directors.

In June 2018, Zai Lab appointed William Liang as Chief Commercial Officer. William brings more than two decades of experience in the pharmaceutical industry, with expertise in commercial launch, strategy and operations. Prior to joining Zai Lab, William served as Vice President at AstraZeneca heading up the Oncology Business Unit in China.

In June 2018, Zai Lab completed construction of a biologics pilot facility using GE Healthcare’s Flex Factory platform technology. The facility is capable of supporting biologics drug products for clinical and non-clinical development of Zai Lab’s drug candidates.

In May 2018, Zai Lab entered into an exclusive worldwide agreement with Crescendo Biologics for ZL-1102, a topical, innovative antibody for potential application in inflammatory indications, including psoriasis.

In April 2018, Zai Lab entered into an exclusive license agreement in Asia-Pacific, and a global development agreement, with Entasis Therapeutics (Entasis) for ETX2514, a novel broad-spectrum intravenous inhibitor of ß-lactamases, for the treatment of a variety of serious multidrug-resistant (MDR) infections. In combination with sulbactam, ETX2514 is particularly active against MDR Acinetobacter baumannii infections.

Zai Lab continues to expand its platform and human resources. As of June 30, 2018, Zai Lab employed 182 full-time employees, including 37 employees with M.D. or Ph.D. degrees. Currently, approximately 85% of the Company’s employees are engaged in R&D activities. Employee mix is projected to change as the Company continues to build out its commercial team.

Zai Lab has, from time to time, evaluated partnership opportunities and may, in the future, make acquisitions of, or investments in, companies that Zai Lab believes have products or capabilities that are a strategic or commercial fit with Zai Lab’s current drug candidates and business or otherwise offer opportunities for the Company.

On September 23, 2018, the design of the Phase III study of ZL-2306 (niraparib) as maintenance therapy in first line platinum-responsive small cell lung cancer (SCLC) patients will be presented at the International Association for the Study of Lung Cancer (IASLC) 19^th World Conference on Lung Cancer (WCLC).

On September 21, 2018, results from a Phase I PK and safety study of ZL-2306 (niraparib) in Chinese patients with epithelial ovarian cancer (OC) will be presented at the 21^st Annual Meeting of Chinese Society of Clinical Oncology (CSCO).

Zai Lab plans to begin commercializing ZL-2306 (niraparib) as a second-line maintenance therapy in patients with recurrent platinum-sensitive ovarian cancer in Hong Kong during the fourth quarter of 2018, and in Macau thereafter.

Zai Lab expects to initiate a bioequivalence and PK bridging study in China to demonstrate comparability in the PK profile of Chinese patients administered with ZL-2401 (omadacycline) to non-Chinese patients, in preparation for its New Drug Application (NDA) submission in China. This program is expected to start in the fourth quarter of 2018.

Paratek Pharmaceuticals has a Prescription Drug User Fee Act (PDUFA) action date set in October 2018 for its NDA for once-daily oral and intravenous formulations of omadacycline for the treatment of community-acquired bacterial pneumonia (CABP) and acute skin and skin structure infections (ABSSSI). On August 8, 2018, Antimicrobials Drug Advisory Committee of the U.S. FDA voted in favor of the approval of IV and oral omadacycline.

In collaboration with Five Prime, Zai Lab plans to initiate patient dosing in the China portion of the randomized, controlled Phase III portion of the Phase I/III FIGHT global registration trial in the fourth quarter of 2018.

In collaboration with Entasis, Zai Lab plans to initiate patient dosing in the Asia-Pacific portion of the Phase III global registration trial of ETX2514 for MDR Acinetobacter pneumonia and bloodstream infections in 2019.

Data from a Phase II trial of ZL-2301 (brivanib) as a second-line treatment for advanced hepatocellular cancer patients in China are expected in the second half of 2018.

On September 22, 2018, preliminary study results from the Phase II trial of ZL-2301 (brivanib) in advanced HCC patients with systemic treatment failure or intolerance will be presented at the 21^st Annual Meeting of Chinese Society of Clinical Oncology (CSCO).

In the fourth quarter of 2018, Zai Lab plans to initiate Phase I clinical trials in China of ZL-2302 for the treatment of patients with non-small cell lung cancer (NSCLC) who have ALK mutations and developed crizotinib resistance and/or brain metastasis.

As of June 30, 2018, cash and cash equivalents and short-term investments totaled $177.7 million.

Research and development expenses were $34.6 million for the six months ended June 30, 2018 compared to $20.9 million for the same period in 2017. The increase was primarily due to higher clinical and preclinical costs from the advancement of the Company’s expanded pipeline, and expansion of research efforts to support internal programs.

General and administrative expenses were $6.4 million for the six months ended June 30, 2018 compared to $4.0 million for the same period in 2017. The increase was primarily due to the increase in payroll and payroll-related expenses as a result of the increased headcount from expanded operations, and increased costs associated with operating as a public company.

For the six months ended June 30, 2018, Zai Lab reported a net loss of $41.5 million, or basic and diluted net loss per share attributable to common stockholders of $0.83, compared to a net loss of $24.4 million, or basic and diluted net loss per share attributable to common stockholders of $2.30, for the same period in 2017.
