For purposes of calculating the average Net Sales per unit sold of a Licensed Component and Other Component(s) of a Combination Product, any of the deductions described herein that apply to such Combination Product shall be allocated among sales of the Licensed Component and sales of the Other Component(s) included in such Combination Product as follows: (i) deductions that are attributable solely to the Licensed Component or one of the Other Component(s) shall be allocated solely to Net Sales of the Licensed Component or such Other Component, as applicable, and (ii) all other deductions shall be allocated among sales of the Licensed Component and sales of the Other Component(s) in proportion to Zai’s and MacroGenics’ mutual agreement of the fair market value of the Licensed Component and the Other Component(s).

In the event that no separate sales of the Licensed Component or any Other Component(s) included in a Combination Product are made by Zai or its Related Parties, during a Calendar Quarter in which such Combination Product is sold, the average Net Sales per unit sold in the above described equation shall be replaced with Zai’s and MacroGenics’ mutual agreement of the fair market value of the Licensed Component and each of the Other Component(s) included in such Combination Product.

MacroGenics and Zai Lab Announce Exclusive Collaboration and License Agreement to Develop and Commercialize Margetuximab, MGD013 and TRIDENT™ Molecule in Greater China

ROCKVILLE, MD, and SHANGHAI, China, Nov. 29, 2018 (GLOBE NEWSWIRE) – MacroGenics (NASDAQ: MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer, and Zai Lab Limited (NASDAQ: ZLAB), a Shanghai-based innovative biopharmaceutical company, announced today that the companies have entered into an exclusive collaboration and license agreement involving three immuno-oncology (I-O) programs from MacroGenics’ pipeline of product candidates:

Zai Lab obtains regional development and commercialization rights for these programs in mainland China, Hong Kong, Macau and Taiwan. Zai Lab will lead clinical development in its territory by leveraging its regulatory and clinical development expertise and broad regional network of investigators. As part of the collaborative clinical development effort, Zai Lab and MacroGenics intend to initiate a global study using combination regimens containing margetuximab in order to maximize potential clinical benefit in gastric cancer, the fifth most common cancer in the world and the second most common in China.

“We believe Zai Lab is an ideal partner to enable us to expand MacroGenics’ global efforts to address patient populations with high unmet medical needs such as gastric cancer,” said Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. “Zai has a strong

track record of rapidly progressing the development of innovative product candidates in China and is well on its way to building its commercial platform. Zai is strongly positioned to take advantage of a growing pharmaceutical market in this region.”

Dr. Samantha Du, Chief Executive Officer of Zai Lab said, “MacroGenics is a leader in the immuno-oncology field and we are thrilled to enter into this comprehensive strategic collaboration for a broad set of innovative assets. We believe we can build off the promising, previously reported results from MacroGenics’ clinical studies of margetuximab in HER2-positive breast and gastric cancer, which are highly synergistic operationally with our other existing pipeline programs. We also look forward to working with MacroGenics in advancing MGD013, an exciting first-in-class I-O program that will help distinguish our pipeline and create combination opportunities with our other oncology assets. We believe this collaboration significantly increases the value of our oncology portfolio and is another step in establishing Zai as a leader in the field of innovative cancer treatments.”

Under the terms of the agreement, MacroGenics will receive an upfront cash payment of $25 million and will be eligible to receive up to $140 million in potential development and regulatory-based milestone payments. In addition, Zai Lab would pay MacroGenics double-digit royalties on annual net sales of the assets, which may be subject to adjustment in specified circumstances.

Zai Lab will host a webcast and conference call to discuss the collaboration and license agreement on Thursday, November 29th, at 8:30 a.m. ET.

Margetuximab is an Fc-optimized monoclonal antibody that targets the human epidermal growth factor receptor 2, or HER2, oncoprotein. HER2 is expressed by tumor cells in breast, gastric, and other solid tumor cancers, making it a key marker for biologic therapy. MacroGenics has completed enrollment of its pivotal Phase 3 SOPHIA study, which is evaluating the treatment of relapsed/refractory HER2-positive metastatic breast cancer patients. MacroGenics anticipates disclosure of topline PFS results from this trial in the first quarter of 2019. In addition to being studied in metastatic breast cancer, margetuximab is also being studied in combination with an anti-PD-1 agent in a Phase 2 clinical trial in gastric cancer, for which data was recently presented at the 2018 European Society of Medical Oncology (ESMO) Congress.

MGD013 is a first-in-class bispecific DART molecule designed to provide coordinate blockade of two immune checkpoint molecules expressed on T cells, PD-1 and LAG-3, for the potential treatment of a range of solid tumors and hematological malignancies. MacroGenics recently established the dose and schedule for MGD013 administration and has initiated dose expansion in up to nine tumor types.

MacroGenics is a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer. The company generates its pipeline of product candidates primarily from its proprietary suite of next-generation antibody-based technology platforms, which have applicability across broad therapeutic domains. The combination of MacroGenics' technology platforms and protein engineering expertise has allowed the company to generate promising product candidates and enter into several strategic collaborations with global pharmaceutical and biotechnology companies.
