- CStone has established a clinical development-driven business model and built a world-class clinical team with significant experience in translational medicine and clinical development. In addition, the Scientific Advisory Board comprised of four internationally renowned immuno-oncologists has substantially strengthened the Company's R&D capabilities in immunotherapies and precision medicines, further enhancing and optimizing CStone's R&D strategies and product pipeline.
- CStone has built a risk-balanced and highly competitive immunotherapy-focused pipeline. Among the Company's 15 cancer drug candidates, five are in pivotal late-stage clinical development. AYVAKITTM (avapritinib), developed by Blueprint Medicines, and TIBSOVO® (ivosidenib), developed by Agios Pharmaceuticals have received NDA approvals from the U.S. FDA.
Among these trials, the clinical studies of CS1001, an anti-PD-L1 monoclonal antibody, have achieved promising clinical results with patients treated with CS1001 exceeding one thousand. In 2019, CStone released encouraging data from the trials of CS1001 in esophageal carcinoma and a number of other large cancer indications in China at major medical conferences, including the American Society of Clinical Oncology (ASCO), the Chinese Society of Clinical Oncology (CSCO), and the American Society of Hematology (ASH) annual meetings.
The two in-licensed products of CStone's pipeline candidates that have received NDA approvals from the U.S. FDA are AYVAKITTM (avapritinib), developed by the partner company, Blueprint Medicines, and TIBSOVO® (ivosidenib), developed by Agios Pharmaceuticals. Moreover, Blueprint Medicine has initiated a rolling NDA submission to the U.S. FDA for pralsetinib. All three candidate drugs are being investigated in multiple registrational trials in China.
In December, 2019, the global Phase III VOYAGER trial of avapritinib in third-line gastrointestinal stromal tumors (GIST), and the global Phase I/II ARROW study of pralsetinib in second- and later-line non-small cell lung cancer (NSCLC) have both completed their targeted enrollments of Chinese patients ahead of schedule.
- CStone developed comprehensive early-stage programs and is scaling up its combination therapy-focused pipeline. The Company has made significant progress with two of its backbone immunotherapy assets, CS1002, an anti-CTLA-4 monoclonal antibody; and CS1003, an anti-PD-1 monoclonal antibody. Both assets generated promising results as monotherapies in Phase I studies, and CS1003 has already entered a global Phase III registrational trial. In the development of combination therapies, CStone recently initiated multiple combination trials and will continue to advance these combination studies in 2020.
- Leveraging a unique and highly efficient R&D platform and an innovation ecosystem, CStone has further strengthened its Pipeline 2.0. The Company will continue to develop first-in-class and best-in-class drugs and therapies to maintain its lead in innovations.
In 2019, CStone advanced two drug candidates in its pipeline into clinical development, and commenced a dozen preclinical research initiatives.
Major milestones expected in 2020 include:
- One New Drug Application approval
TIBSOVO®, for the treatment of R/R AML, is expected to receive an NDA approval in Taiwan and become CStone's first commercialized product in the Greater China region.
- 5 NDA submissions
CStone plans to submit five new drug applications in Mainland China and Taiwan, for CS1001, pralsetinib, and avapritinib.
- Seven clinical trial data releases
CStone plans to release top-line data from seven clinical trials of CS1001 (an anti-PD-L1 monoclonal antibody), pralsetinib, and avapritinib, and six of these trials are registrational studies.

Key messages from KOL speakers
- Dr. Paul Bunn, MD, former President of American Society of Clinical Oncology (ASCO) and Distinguished Professor at University of Colorado Cancer Center, commented that latest clinical data of the RET inhibitor pralsetinib were very encouraging. The trial has already completed the patient target enrollment, which included naïve patients and patients who have received platinum-based chemotherapy. He expects this precision medicine will benefit cancer patients in the future.
- Dr. Eytan Stein, MD, Professor at the Memorial Sloan Kettering Cancer Center, commented that compared to current standard chemotherapies, ivosidenib could bring significant clinical benefits to AML patients and its high-selectivity could broaden clinical benefits to cancer patients with an IDH1-mutation.
- Dr. Yilong Wu, MD, President of the Chinese Thoracic Oncology Group (C-TONG), past president of Chinese Society of Clinical Oncology (CSCO), tenured professor of Guangdong Provincial People's Hospital and Guangdong Lung Cancer Research Institute, emphasized that CStone has initiated three registrational lung cancer trials and the Company will play an important role in the lung cancer field in China.
- CS1001 is currently being investigated in the Phase III GEMSTONE-301 study in patients with locally advanced or unresectable NSCLC, and it could potentially benefit a wide range of patients. Considering the clinical practices in China, the trial also included patients who had received either concomitant or sequential radiochemotherapy. In addition, CS1001 is also being investigated in a Phase III trial in first-line Stage IV NSCLC.
- The study of pralsetinib in RET-fusion NSCLC has demonstrated promising clinical utility. Due to the persistent high incident rate of lung cancers and the lack of any effective treatment for RET-mutant cancers, pralsetinib has the potential of effectively addressing the current treatment gap in RET-fusion NSCLC in China.
- Dr. Jian Li, MD, Professor at Beijing Cancer Hospital and Chairman-elect of the Chinese Society of Clinical Oncology's (CSCO) Committee on GIST, acknowledged avapritinib's therapeutic promise in the treatment of GIST in China. Avapritinib is a first-in-class precision medicine approved by the U.S. FDA for the treatment of GIST, and there is currently no effective treatment for PDGFRA D842V mutant GIST in China. Available clinical data of avapritinib in PDGFRA exon 18 mutant GIST (including PDGFRA D842V mutations) have demonstrated compelling antitumor activity and a more tolerable safety profile. The drug could significantly benefit GIST patients who are in need of effective treatment options.
- Dr. Weiping Zou, MD, PhD, Professor at University of Michigan, Director of the Center of Excellence for Cancer Immunology and Immunotherapy, and Chair of the American Association of Cancer Research's (AACR) Cancer Immunology Working Group (CIMM), commented that CStone has made significant progress in the past three years, and he will likely to further collaborate with the Company in selecting Class I drug targets for future development and he looks forward to facilitating CStone's transition to Pipeline 2.0.
