Shanghai, China, April 10, 2023 – Jiangsu Hengrui Pharmaceuticals Co., Ltd. (“Hengrui Pharma”), a global pharmaceutical company, today announced that there will be five poster presentations showcased at the 2023 American Association for Cancer Research (AACR) Annual Meeting taking place in Orlando, April 14-19, 2023. The plasma stability of an antibody-drug conjugate (ADC) is of crucial importance as it impacts both safety and efficacy. The free payload in plasma contributes to certain adverse events that are commonly seen in marketed ADCs. Hengrui Pharma developed a unique ADC platform with an improved molecular design to increase plasma stability and enhance bystander effect. Better safety and efficacy were observed in both preclinical and clinical studies for multiple ADC assets of Hengrui Pharma. These posters will highlight:

• Superior bystander effect of SHR-A1811, a novel anti-HER2 antibody-drug conjugate (ADC), with optimal drug-antibody ratio (DAR), and favorable safety profiles;
• Clinical data of SHR-A1811 in phase 1 study for patients with HER2-expressing/mutated advanced solid tumors;
• Clinical data of SHR-A1811 in phase 1/2 study for patients with advanced HER2-mutant non-small cell lung cancer (NSCLC);
• An optimized design and well-balanced profile between efficacy and safety of SHR-A1921, a novel TROP-2 ADC; and
• Clinical data of SHR-A1921 in phase 1 study for patients with advanced solid tumors.

Details of the presentations are as follows:

About SHR-A1811

SHR-A1811, a HER2-targeted ADC, features an optimized molecular design to enhance plasma stability and bystander effect. Hengrui Pharma is currently conducting more than 10 clinical studies of SHR-A1811 from phase 1 to phase 3 to evaluate its safety and efficacy as single agent or combination therapy in a wide variety of cancer indications. Breakthrough Therapy Designations were granted to SHR-A1811 by the China National Medical and Products Administration for three indications, which include:

• For the treatment of HER2-mutant, advanced NSCLC after platinum-based chemotherapy
• For the treatment of HER2-positive, recurrent or metastatic breast cancer
• For the treatment of HER2-low, recurrent or metastatic breast cancer

About SHR-A1921

SHR-A1921 consists of an anti-TROP-2 antibody attached to a novel topoisomerase I inhibitor payload via a cleavable linker. This molecular design enhances plasma stability and bystander effect with a well-balanced profile between efficacy and safety. A pivotal phase 3 trial of SHR-A1921 versus docetaxel for the second- or later-line treatment of NSCLC is expected to be initiated in China in 2023.
