SUZHOU, China, Aug. 25, 2022 /PRNewswire/ -- CStone Pharmaceuticals ("CStone", HKEX: 2616), a leading biopharmaceutical company focused on research, development, and commercialization of innovative immuno-oncology therapies and precision medicines, today reported 2022 interim financial results and recent business highlights, and leadership transition.
In the first of 2022, CStone continued to achieve breakthroughs with eye-catching performance. So far this year, we've obtained four NDA approvals for three of our innovative drugs. With the successful launch of potential best-in-class drug CEJEMLY® and first-in-class drug TIBSOVO®, we now have four commercial-stage products that position us as a leader in the biotech sector in China. We leveraged our well-established commercial operation system to rapidly advance commercialization through diverse paths. Thanks to our various initiatives and effective delivery, our product revenue grew steadily.
Innovation is the cornerstone for a biopharmaceutical company. This year, we've submitted two NDAs and presented clinical data at multiple international academic conferences. The clinical data from sugemalimab in stage III and stage IV NSCLC were published in the world-leading clinical oncology journal, The Lancet Oncology. Patient enrollment wrapped up in several phase 3 registrational studies. In addition, the first patient was enrolled in the pivotal study of lorlatinib, which we are co-developing with Pfizer, for the treatment of c-ros oncogene 1 (ROS1)-positive advanced NSCLC. With all these efforts, we are further diversifying our pipeline to meet patient needs and maximize the commercial value of our products.
Our Pipeline 2.0 strategy was in full swing as we secured breakthroughs in early-stage pipeline. The investigational new drug applications were approved in the U.S., Australia, and Mainland China for CS5001, a potential global best-in-class antibody-drug conjugate (ADC), targeting receptor tyrosine kinase-like orphan receptor 1 (ROR1), and the first patient has been dosed in a multi-regional clinical trial in the U.S. We've also been gearing up more than 10 early discovery and technology platform projects, with several of them achieving milestones.
We worked more closely with key global strategic partners to accelerate our commercialization agenda and further bolster our first-in-class/best-in-class early-stage pipeline. We officially launched CStone Global Industrialization Base, and are enabling technology transfer for several products in a bid to improve our long-term profitability.
CStone will continue to enhance its organic R&D and forge ahead with more than ten early discovery projects. It will expand strategic partnerships with its robust clinical development capabilities, accelerate commercialization to maximize product value and bolster financial performance to respond to market changes in an agile way.

Business Highlights
The first half of 2022 has been fruitful for CStone with milestones across our maturing pipeline and business. Our commercial successes in the first half, including the launch of two First-in-Class ("FIC")/Best-in-Class ("BIC") therapies, put us in an elite tier of innovative biopharmaceutical companies from China as we now have four products in market and generating recurring revenue to provide financial strength and fund further growth initiatives. For the six months ended June 30, 2022 and as of the date of this announcement, significant progress has been made with respect to our product pipeline and business operations. A shortlist of our achievements over this period includes:
These achievements represent only a snapshot of what we have accomplished.
We have achieved healthy and steady growth in commercial capabilities, demonstrated again in our new product and indication launches, as well as increasing brand influence. We have remained focused on key innovative initiatives that will drive continuous growth: 1) enhancing clinical education and testing assistance to expand the pool of potential patients for our drugs; 2) further building-out scientific leadership by broadening the influence of guideline inclusions through academic activities; 3) optimizing our pricing strategy, improving hospital/direct-to-patient ("DTP") pharmacy listing and entering into more insurance programs to expand accessibility and affordability; and 4) providing physician/patient education for better patient support and long-term medication. We have specifically focused our efforts on ensuring dedicated sales force coverage and enhancing sales productivity.
Our efforts to date have led to several successes. We have expanded our sales force coverage to approximately 700 hospitals as of the date of this announcement, up from 600 in 2021, accounting for approximately 70-80% of the relevant market for precision medicines. Currently, our in-market precision medicines have been included in 15 national guidelines, up from over ten at the time we released our 2021 annual results. In addition, they have been listed in 85 supplemental insurance plans, up from over 60 at the time we released our 2021 annual results.
Our clinical team has demonstrated the ability to translate our advantages in innovation, speed, and quality into tangible results for patients and our business. We successfully obtained four NDA approvals covering three products, including two FIC precision medicines as well as our flagship immuno-oncology backbone drug. During the Reporting Period, sugemalimab received approval from the National Medical Products Administration ("NMPA") for patients with stage III NSCLC without disease progression after concurrent or sequential chemoradiotherapy, making it the world's only anti-PD-1/PD-L1 monoclonal antibody approved in this patient population, significantly strengthened its market positioning and adoption momentum. Ivosidenib, a first-in- class drug, was approved in mainland China for adult patients with R/R AML who have an IDH1 mutation. In addition, pralsetinib received approval for RET-mutant MTC and RET fusion-positive TC in mainland China, and received approval for RET fusion-positive NSCLC in Hong Kong, China.
The broader spectrum of our clinical development success is reflected in the fact that CStone had four data presentations at the 2022 American Society of Clinical Oncology Annual Meeting (ASCO 2022) and the 2022 World Conference on Lung Cancer (WCLC 2022), and three publications on The New England Journal of Medicine and The Lancet Oncology as of the date of this announcement. These presentations and publications covered study results of sugemalimab in stage III NSCLC, stage IV NSCLC and R/R ENKTL, nofazinlimab combined with lenvatinib in hepatocellular carcinoma ("HCC") and ivosidenib in first-line acute myeloid leukemia ("AML"). In addition to the late-stage clinical development programs, meaningful progresses have also been made in our two early-stage programs since the last report including the progression into proof-of- concept ("PoC") expansion cohorts in the global phase I study of CS2006 (NM21-1480; PD-L1/4- 1BB/HSA tri-specific) and robust enrolment of the FIH study of CS5001 (ROR1 ADC) in the U.S. and Australia.
Our research team has continued to make advances in our innovative early-stage programs, based on our "Gemstones on the Ring" research strategy. This strategy capitalizes on the modular "plug- and-play" nature of biologics. Following this research framework, we have in progress a total of over ten discovery projects and expect two potential FIC/BIC immune-oncology programs declaring pre-clinical candidates ("PCCs") this year, including one tri-specific molecule against PD-L1, VEGF plus another immuno-oncology ("I/O" or "IO") target, and one antibody-cytokine fusion molecule. Additionally, we have made great strides in our proprietary cell-penetrating therapeutic platform for targeting intractable intracellular proteins by achieving PoC in vitro for one of the treatment modalities using this platform.
Lastly, we launched pilot operations of our manufacturing facility as expected. We are steadily advancing our readiness for full-scale operations to produce our products for clinical trials as well as commercial sales. We are also in the process of technology transfer for multiple imported products which will reduce costs and improve long-term profitability of our products. Specifically, we have completed the technology transfer submission to Center for Drug Evaluation of NMPA ("CDE") for avapritinib in July 2022.
I. Multiple Product Launches and Continued Robust Commercial Efforts
Since 2021, we have obtained a total of nine NDA approvals for four products, including four NDA approvals for three products as at the date of this announcement. Our commercial team continued its rapid execution of pre-launch and post-launch efforts to set the stage for market adoption of our products. TIBSOVO® (ivosidenib) received NDA approval in January 2022, achieved successful commercial launch in June 2022 (first prescriptions on June 8), and gained endorsement from all top KOLs in hematology.
Meanwhile, they have kept up robust efforts to engage the healthcare community, including healthcare providers, academic societies, patient groups, hospitals, pharmacies, payors, and other stakeholders, to provide education on our products and demonstrate our scientific leadership. In addition, they have expanded accessibility and affordability of our products through various patient identification programs and by working with payors to promote coverage of them in insurance programs.
Highlights and details on our commercial activities as of the date of this announcement are as follows:
II. Innovation, High Quality and Rapid Execution Lead to Advances across a Maturing Pipeline
CStone followed through on an aggressive clinical agenda with further developments across its pipeline. As of the date of this announcement, we have secured four NDA approvals and submitted two NDA filings as we rounded out our diverse and maturing pipeline of in-market and near-commercial ready drugs. In doing so, our clinical engine once again distinguished itself in terms of innovation, speed, and quality, as evidence by the facts that it took only six months for ivosidenib from NDA acceptance to NDA approval, and we had seven data presentations/publications at/on global academic conferences/top-tier medical journals.
Details are as follows:
III. Research Efforts Harness Biologics Modular Potential and Reinforce Core IO Franchise
Precision medicines and immuno-oncology combinations remain our strategic focus. Antibody-drug conjugates which deliver cytotoxic agents to tumor with precision, and multi- specific biologics which can create new biology and are combinations of themselves represent two near-term modalities for early-development.
Our research team has continued to make momentous progress in advancing the early-stage innovative programs, predicated on our "Gemstones on the Ring" research strategy which capitalizes on the modular "plug-and-play" nature of biologics. Following this research framework, we have in progress a total of over ten discovery projects and expect two potentially FIC/BIC immune-oncology programs declaring PCCs this year. Additionally, we have made great strides in our proprietary cell-penetrating therapeutic platform for targeting intractable intracellular proteins by achieving PoC in vitro for one of the treatment modalities using this platform. We have established a sustainable innovative research engine that utilizes clinical insights and translational knowledge to drive discovery, and will continue to strengthen our model of innovation sourcing through organic research at our new global R&D Center in Suzhou, China, as well as collaboration with our business partners. These initiatives bolster our immuno-oncology and precision medicine franchises and enhance our capacity to meet our long-term target of filing one-two INDs per year.
We have made significant progress year-to-date with several initiatives:
IV. Strategic Relationships Advance Commercialization Activities and Pipeline Development
We continue to grow and deepen relationships with key global strategic partners to expand commercialization of our in-market and late-stage drugs, bolster our early-stage pipeline of potential FIC/BIC molecules, and access technologies that complement our research and development efforts.
To begin with, we made significant progress on our relationship with Pfizer this year. In May 2022, we received the second indication approval of sugemalimab as a consolidation therapy to improve progression-free survival in patients with stage III NSCLC, after concurrent or sequential platinum-based chemoradiotherapy. Moreover, for the co-development program of lorlatinib for the treatment of ROS1-positive advanced NSCLC, the first patient was enrolled in the pivotal study in May 2022 under the joint efforts of CStone and Pfizer.
With EQRx, we are advancing regulatory submission in multiple countries and jurisdictions all around the world – the U.S., the U.K., and the EU – regarding the registration of sugemalimab for NSCLC and ENKTL indications. We are collaborating with EQRx to explore the feasibility of extending indications for this drug in the global market including gastric cancer and esophageal cancer. In addition, we are working with EQRx on a global phase III study of nofazinlimab in HCC in the U.S. and major EU markets.
In addition, we further strengthened the strategic partnership with Jiangsu Hengrui Pharmaceuticals Co., Ltd. ("Hengrui"). Last year, CStone and Hengrui established a strategic partnership by leveraging respective R&D and commercial expertise to accelerate the development and commercialization of our anti-CTLA-4 mAb (CS1002) to fully unleash its commercial value. In the first half of 2022, Hengrui received the IND clearance from NMPA for a phase Ib/II trial of CS1002 combination therapy for the treatment of advanced solid tumors.
V. Other Business Updates
Manufacturing. We have completed construction of our state-of-the-art manufacturing facility and began running pilot operations at the end of 2021 as projected. The manufacturing facility has a capacity of 26,000 liters for biologics and 1 billion tablets/capsules for small molecule drugs. We are also in the process of technology transfer for multiple imported products which will reduce costs and improve long-term profitability of our products. Specifically, we have completed the technology transfer submission to CDE for avapritinib in July 2022.
