Thank you, Samantha. Our comment on the launch performance of our three commercial products and on progress we have made in the quarter in our main disease franchises: lung cancer, gastric cancer, hematology, autoimmune disorders and infection diseases. ZEJULA continued to perform very well in the second quarter and we achieved significant sequential revenue growth. As a reminder, ZEJULA is approved in China for first and second-line ovarian cancer and is the only PARP inhibitor monotherapy approved for all-comers in the first line. So, this provides significant differentiation from other PARP inhibitors. The inclusion of ZEJULA in NRDL starting from March of this year provided a major momentum for the ZEJULA launch. One key leading indicator for the successful launch and NRDL implementation is hospital listing. Our team has been laser focused on increasing hospital listings and as of June 30, 2021, ZEJULA has been listed in more than 800 hospitals in China, which represents a more than sevenfold increase from just prior to the NRDL implementation in March 2021. Combined with the differentiated label, our successful market asset strategy lays the foundation for strong volume growth in the second half of the year and beyond. We remain confident that over time, ZEJULA will become the market leading PARP inhibitor in ovarian cancer in China. Similarly, the launch of Optune is going well. As a reminder, Optune is the first innovative medical device supported by commercial health insurance in China and also has been covered in 14 supplemental insurance plans since its launch in June 2020. During the second quarter, we held extensive multidiscipline physician education campaigns to increase brand adoption and we were pleased with the feedback we received from treatment specialists. Importantly, on the development side, we are working with our partner, Novocure to extend indications of tumor treating fields in areas of large unmet medical need globally and in China. We look forward to additional clinical data readouts in lung, pancreatic, liver and ovarian cancers, in brain metastasis and in glioblastoma with high-intensity arrays over the next few years. And we continue to target a filing of tumor treating fields for malignant pleural mesothelioma later this year. As Samantha mentioned, we achieved another important commercial milestone in successfully launching QINLOCK in fourth-line GIST in China in May, our third oncology launch in the last 16 months. QINLOCK is another great example of our track record of accelerating regulatory filing and approval of innovative oncology products. We were able to file the NDA for QINLOCK in China only 2 months after FDA approval and we received NMPA approval 8 months after NDA acceptance. In July, QINLOCK was included in the Chinese Society of Clinical Oncology guidelines for diagnosis and treatment of gastrointestinal stromal tumors 2021 as an option for second-line treatment for advanced GIST patients. We are encouraged by our initial launch performance and look forward to updating you with our progress through the remainder of the year. Let’s move on to progress in our product pipeline. Starting in lung cancer, where we continue to build a disease stronghold with 6 products currently in clinical development. In June, we entered into an important strategic collaboration with Mirati and obtain the right to research, develop, manufacture and exclusively commercialize adagrasib, a potential best-in-class small molecule KRAS G12C inhibitor in Greater China. Adagrasib received FDA breakthrough therapy designation in June for the potential treatment of non-small-cell lung cancer patients who harbor the KRAS G12C mutation following prior systemic therapy. Zai will support accelerated enrollment in key global registration-enabling clinical trials of adagrasib in KRAS G12C cancer patients, including non-small-cell lung cancer and colorectal cancer. Mirati has announced their intention to file adagrasib for second-line non-small-cell lung cancer in the U.S. in the second half of 2021. We believe adagrasib has best-in-class potential and we will also aim to make it first-in-class in China where there are currently no ongoing clinical trials in this product category. Adagrasib is a great addition to our lung cancer franchise and complements other promising byproducts being developed for lung cancer, including tumor treating fields, repotrectinib, CLN-081 and TPX-0022. For tumor treating fields, Zai initiated the China portion of the Phase 3 pivotal LUNAR trial and the Phase 3 pivotal METIS trial in brain metastasis for non-small-cell lung cancer. You will recall that in May, Novocure announced that the FDA approved their IDE supplement for LUNAR, reducing enrollment requirement by about a half and shortening the required patient follow-up from 18 months to 12 months, potentially accelerating a completion of the trial by more than a year. For CLM-081, in June, Zai’s partner Cullinan announced Phase 1/2a interim data in non-small-cell lung cancer EGFR exon-20 patients. CLN-081 continues to demonstrate its best-in-class potential with good activity and encouraging safety and tolerability. Let’s move on to gastric cancer, a Zai disease stronghold with 7 products currently in clinical development, including QINLOCK and demurocizumab. As I mentioned earlier, we are actively launching QINLOCK in fourth-line GIST supported by the compelling data generated from the INVICTUS Phase 3 study. In the second half of this year, our partner, Deciphera, expect to receive data from the INTRIGUE trial of QINLOCK versus sunitinib in second-line GIST. Other gastric cancer products also made significant progress in the quarter, including bema, the monoclonal antibody against FGFR2b. In April 2021, Zai’s partner Amgen was granted breakthrough therapy designation by the FDA for bema as a first-line treatment for patients with FGFR2b overexpressing HER2 negative metastatic and locally advanced gastric and gastroesophageal junction adenocarcinoma in combination with modified FOLFOX. In June, Zai’s partner Turning Point was granted orphan drug designation by the FDA for TPX-0022 in gastric cancer, including gastroesophageal junction adenocarcinoma. In our hematology franchise, in May 2021, Zai’s partner Regeneron resumed enrollment in the Phase 2 potentially pivotal clinical trial of odronextamab in patients with follicular lymphoma and diffuse large B-cell lymphoma. We look forward to initiating this important clinical trial in China. Since our last earnings call, we also entered into two other strategic research and development collaboration to bolster our global oncology pipeline. In June, Zai and MacroGenics announced that the two companies have entered into an exclusive collaboration and license agreement involving up to 4 immunooncology molecules. The first collaboration program covers the lead research molecule that incorporates MacroGenics to DART platform and binds CD3 in an undisclosed target that is expressed in multiple solid tumors. The second program covers the target to be designated by MacroGenics. For both molecules, Zai received commercial rights in Greater China, Japan and Korea and obtains an option to convert the lead research program into a global 50-50 profit sharing arrangement upon achieving a predefined clinical milestone. For two additional early-stage molecules, Zai Lab has exclusive global development and commercial rights. Earlier this month, Zai and Schrödinger announced a global discovery, development and commercialization collaboration focused on a novel target in the DNA damage response pathway, a key research interest for Zai Lab in oncology. Schrödinger is an industry leader in providing computational platforms using drug discovery. The research program will be conducted jointly by the two company scientific teams and Zai Lab will have exclusive development and commercial rights globally. This initiative will complement our existing discovery efforts in DNA damage response pathway in addition to potential combinatorial approaches within our pipeline with such products as the PARP inhibitor, ZEJULA and ZL-2309. In our autoimmune franchise, in July, Zai Lab’s partner, argenx, announced myositis and bolus pemphigoid as two new indications for efgartigimod at its R&D Day. Today, five clinical trial applications for efgar filed by Zai have been approved. With all of this progress, as you can see, Zai’s development and commercialization operations are hitting on all cylinders. We have an abundance of growth opportunities and we very much look forward to sharing our further progress with you throughout the year. And now, Billy will discuss our financial results in the quarter.
