• In January 2023, we announced that the GEMSTONE-304 study for the first- line treatment of unresectable locally advanced, recurrent, or metastatic ESCC has met its primary endpoints. Sugemalimab in combination with chemotherapy demonstrated a statistically significant and clinically meaningful improvement in progression-free survival ("PFS") and OS compared with placebo in combination with chemotherapy. We presented the detailed results at the ESMO GI Congress in June 2023.

– R/R ENKTL:

• In March 2023, we announced that the results of the registrational GEMSTONE-201 study in patients with R/R ENKTL were published in a top-tier oncology journal – Journal of Clinical Oncology.

• Pralsetinib (CS3009, RET inhibitor)

– In January 2023, we received the NDA approval from the Taiwan Food and Drug Administration ("TFDA") for the treatment of patients with RET fusion-positive locally advanced or metastatic NSCLC, and advanced or metastatic RET-mutant MTC and RET fusion-positive TC.

– In June 2023, we received the NDA approval from the NMPA for the first-line treatment of patients with RET fusion-positive locally advanced or metastatic NSCLC who have not been previously treated with systemic therapy.

– In June 2023, we published updated results from the phase I/II ARROW trial in Chinese patients with RET fusion-positive NSCLC in Cancer.

• CS5001 (LCB71, ROR1 ADC)

– The global FIH study of this potential best-in-class ("BIC") ROR1 ADC has shown swift recruitment to the dose-escalation part in the U.S. and Australia with good safety and tolerability demonstrated. This multi-regional clinical trial has now expanded to include China, further accelerating the development of this product. As one of the most advanced ROR1 ADCs in clinical development, CS5001 has therapeutic potential for various hematological and solid malignancies.

– CS5001 has many distinctive features, including proprietary site-specific conjugation, tumor-cleavable linker, and prodrug technology. CS5001 demonstrated a BIC potential in mantle cell lymphoma and triple negative breast cancer xenograft models compared to a benchmark ROR1 ADC. In addition, CS5001 demonstrated a bystander effect in in vitro co-culture systems, suggesting that solid tumors with heterogeneous/low expression of ROR1 may also benefit. In March 2023, we presented the translational data of CS5001 in an oral session at the 13th world ADC London conference ("World ADC London").

– In addition, we have identified a promising candidate ROR1 antibody clone for immuno-histochemistry ("IHC") to enable biomarker-driven patient selection based on tumor ROR1 expression, supporting precision medicine efforts in the future.

• Ivosidenib (CS3010, IDH1 inhibitor)

– In January 2023, we completed the China bridging study of ivosidenib in R/R AML patients.

– In May 2023, we reached alignment with CDE on the regulatory pathway toward full approval of ivosidenib as a treatment for R/R AML, and application dossiers are currently under preparation.

• Avapritinib (CS3007, KIT/PDGFRA inhibitor)

– In May 2023, our partner, Blueprint Medicines, received NDA approval from the U.S. Food and Drug Administration ("FDA") for the treatment of adults with indolent systemic mastocytosis.

– In June 2023, we presented new data of avapritinib in patients with advanced GIST at the American Society of Clinical Oncology ("ASCO") Annual Meeting 2023.

• Lorlatinib (ALK/ROS-1 inhibitor)

– We are working with Pfizer to jointly develop lorlatinib in Greater China and conducting a pivotal study in patients with ROS1-positive advanced NSCLC. In June 2023, we completed the patient enrollment for this study.

III. Building out Research Pipeline Leveraging Multiple Sources of Innovation

Precision medicines and immuno-oncology combinations remain our strategic focus. ADCs which deliver cytotoxic agents to tumors with precision, and multi-specific biologics which can create new biology and combinations represent two near-term modalities for early development.

We have made significant progress in the first half of 2023 with several initiatives:

• First-in-Class ("FIC") ADCs: Two FIC ADC programs are progressing toward preclinical candidate ("PCC") nomination, including one where a novel tumor-associated antigen which is expressed in multiple large tumor indications was identified using an in-house machine-learning bioinformatic algorithm. Candidate antibodies have been selected, and the conjugated lead molecules have demonstrated encouraging in vitro potency and in vivo efficacy. Investigational new drug applications ("INDs") are expected to be filed in 2024 or 2025.
• I/O multi-specifics: CS2009, which is a tri-specific molecule against PD-1, VEGF plus another I/O target, is under cell line development. IND is expected to be filed in 2024. Additionally, two other I/O multi-specific programs are progressing through IND-enabling and PCC selection phases, respectively.
• Cell penetrating therapeutic platform: Numerous well-known oncology targets are intracellular proteins deemed undruggable by current therapeutic approaches. We are developing a proprietary CPT 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 have obtained in vitro PoC using this platform for three treatment modalities thus far and observed drug-like in vivo pharmacokinetics as well as tumor bio-distribution.

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.

On February 22, 2023, Blueprint Medicines announced that they will regain global commercialization and development rights to pralsetinib from Roche, excluding Greater China. The transition is scheduled to be completed in February 2024, and Blueprint Medicines has initiated a process to re-partner pralsetinib outside of Greater China. We are currently working together with Roche and Blueprint Medicines to take necessary steps to ensure continuity of supply of pralsetinib for patients in Greater China.

Under our partnership with Jiangsu Hengrui Pharmaceuticals Co., Ltd. ("Hengrui") for anti-CTLA-4 mAb (CS1002), a phase Ib/II trial of CS1002 combination therapy for the treatment of advanced solid tumors including HCC and NSCLC is being conducted by Hengrui.

We regained rights for the development and commercialization of sugemalimab and nofazinlimab outside of Greater China, with the termination of the License Agreement for sugemalimab and nofazinlimab between CStone and EQRx on May 9, 2023. The transition has been completed in August 2023. Currently, we are leading the regulatory process for sugemalimab MAA reviews by the EMA and the U.K. MHRA. The termination of this License Agreement will not affect the upfront and milestone payments previously received from EQRx. We are currently exploring potential partnership opportunities for both sugemalimab and nofazinlimab outside of Greater China.

V. Other Business Updates

Manufacturing. We are also in the process of technology transfer for multiple imported products which is expected to reduce costs and improve long-term profitability of our products. Specifically, the application relating to technology transfer for avapritinib is under review by the CDE.
