II. Innovation, High Quality and Rapid Execution Lead to Advances across an Evolving 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 five NDA approvals and submitted seven NDA filings as we rounded out our diverse and evolving 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 evidenced by the facts that it took only six months for ivosidenib from NDA acceptance to NDA approval, and we had eleven data presentations/publications at/on global academic conferences/top-tier medical journals.
Details are as follows:
- Sugemalimab (CS1001, PD-L1 antibody), became the first anti-PD-1/PD-L1 monoclonal antibody approved for both stage III and stage IV NSCLC in China.
– In May 2022, we received the NDA approval from the NMPA for the treatment of patients with unresectable stage III NSCLC whose disease has not progressed following concurrent or sequential platinum-based chemoradiotherapy. Sugemalimab became the first anti-PD-1/PD-L1 monoclonal antibody approved in this patient population.
– In May 2022, we announced that the final progression-free survival ("PFS") analysis of the registrational GEMSTONE-301 study further demonstrates sugemalimab's robust efficacy and significant clinical benefits shown in interim analysis in stage III NSCLC patients.

– In January 2022, we received an NDA approval from the NMPA for the treatment of adults with R/R AML with an IDH1 mutation.
– In October 2022, we received Pediatric and Minority Serious Disease Designation from TFDA for IDH1-mutated R/R AML in adults.
- Lorlatinib (ALK/ROS-1 inhibitor)
– We are working with Pfizer to jointly develop lorlatinib for c-ros oncogene 1 ("ROS1")-positive advanced NSCLC in Greater China. In May 2022, we enrolled the first patient in the pivotal study of lorlatinib for the treatment of ROS1- positive advanced NSCLC. The enrolment continues at a steady pace.
- CS5001 (LCB71, ROR1 ADC)
– After obtaining an approval of the IND application from the U.S. FDA and approval from the Australia Ethics Committee ("EC"), the FIH study of this potential best-in-class receptor tyrosine kinase-like orphan receptor 1 ("ROR1") antibody-drug conjugate ("ADC") has shown swift recruitment to the dose-escalation part in both countries. Additionally, we submitted an IND application to the NMPA in March 2022 and received the approval in May 2022. To enable biomarker-driven patient selection based on tumor ROR1 expression, we have identified candidate ROR1 antibody clones for immuno-histochemistry ("IHC") to support such precision medicine effort in the future.
- CS2006 (NM21-1480, PD-L1/4-1BB/HSA tri-specific molecule)
– The FIH study is ongoing and includes sites in the U.S. and Taiwan. The dose-scalation part of the study has been completed, and the maximum tolerated dose ("MTD") was not reached; preliminary data from the dose escalation part was presented at the Society of Immunotherapy Cancer ("SITC") 2022, which indicated a benign and differentiated safety profile with no notable liver toxicities; an unconfirmed Partial Response was observed in a colorectal cancer subject; meanwhile, full 4-1BB agonism was observed across a broad dose range providing complete inhibition of PD-L1, thus, clinically validating the concept of affinity-balancing built into the design of the molecule. The study has proceeded to proof of-concept ("PoC") stage to further explore the safety and efficacy of CS2006 in selected tumor indications in U.S., E.U. and Taiwan. We received the IND approval from the NMPA in September 2021. We presented the preclinical data at American Association for Cancer Research ("AACR") 2022.
III. Building out Research Pipeline Leveraging Multiple Sources of Innovation
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.
We have made significant progress in 2022 with several initiatives:
- One FIC/BIC I/O program declared PCC in 2022, which is a tri-specific molecule against PD-L1, VEGF plus another I/O target. Another FIC/BIC I/O program (antibody-cytokine fusion molecule) and up to two other I/O multi-specific programs are on track for PCC declaration in 2023.
- Cell-penetrating therapeutic platform. Many well-known oncology targets are intracellular proteins that are considered undruggable by current therapeutic approaches.
We are developing a proprietary cell-penetrating therapeutic platform against these otherwise intractable targets. Significant progress has been made in the development of this platform with broad therapeutic potential for oncology and beyond. We obtained in vitro PoC using this platform with several treatment modalities in 2022 and expect additional in vitro/in vivo PoCs with multiple additional treatment modalities in 2023.
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 continued to make significant and smooth progress on our relationship with Pfizer to explore China markets for sugemalimab. In addition, we are working with EQRx on exploring global markets for sugemalimab and a global phase III study of nofazinlimab in HCC.
In 2022, we entered into a new partnership with Roche Pharmaceuticals Co., Ltd ("Roche") who became the global marketing authorization holder ("MAH") for pralsetinib. As part of this agreement, we acquired full manufacturing right to pralsetinib. Locally manufactured supply is expected to provide significant cost saving and as a result improve CStone's overall profitability. In the meantime, Roche will be responsible for the manufacturing and supply of pralsetinib for China before our successful technology transfer. On February 22, 2023, Roche announced that Blueprint Medicines will regain global commercialization and development rights to pralsetinib in the future, excluding Greater China. Under the terms of the agreement, the termination will be effective within 12 months from the notification date of February 22, 2023. CStone is currently working together with Roche and Blueprint to take necessary step to maintain the marketing authorization for Pralsetinib and ensure continuity of supply of Pralsetinib for patients in China.
We further strengthened the strategic partnership with Jiangsu Hengrui Pharmaceuticals Co., Ltd. ("Hengrui"). In 2021, 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 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, and has initiated two studies in HCC and NSCLC respectively.
V. Other Business Updates
Manufacturing. 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 and bio-equivalence ("BE") has been demonstrated to support technology transfer. At the same time, the technology transfer for pralsetinib is in progress smoothly.
FUTURE AND OUTLOOK
We are working to bring a number of significant clinical and commercial developments to fruition that will be catalysts for our growth in the rest of 2023. A detailed breakdown of expected developments for the remainder of 2023 is below.
Our commercial team is working rapidly to expand the addressable market for our products and maximize their commercial potential with a focus on the following:
