Highlights:

AI-enabled collaboration to engineer KKLC1-targeting TCRs for Zelluna’s TCR-NK platform
Builds on successful engineering of MAGE-A4 TCR underpinning ZI-MA4-1, approved for clinical testing in February 2026
Expands pipeline with validated solid tumour antigen expressed across multiple difficult-to-treat cancers
AI-guided in silico engineering to enhance specificity, potency and development efficiency
The collaboration will focus on the engineering of high-affinity, tumour-specific TCRs targeting KKLC1, a validated cancer antigen found in multiple difficult-to-treat solid tumours. The engineered receptors will be fully owned by Zelluna and developed for use within Zelluna’s proprietary TCR-NK platform. In-vitro data demonstrating safety, specificity and functional activity is now expected in Q4 2026.

This collaboration builds on Zelluna’s successful engineering of a T cell receptor (TCR) designed to recognise the cancer antigen MAGE-A4. This receptor is the targeting module of the company’s lead product candidate ZI-MA4-1, which in February 2026 received approval from the UK Medicines and Healthcare products Regulatory Agency (UK MHRA) to initiate clinical testing. By engineering receptors targeting KKLC1, Zelluna is expanding its product portfolio beyond MAGE-A4 and can thereby address a broader spectrum of solid cancers and patients.

"Our lead product candidate ZI-MA4-1 is built on an affinity enhanced receptor that recognises cancer cells with the MAGE-A4 protein. We developed this receptor in our first highly successful collaboration with Etcembly," said Luise Weigand, Chief Scientific Officer of Zelluna. "We are now delighted to continue our collaboration on our next programme targeting KKLC1. By combining artificial intelligence with our cell therapy platform, we aim to develop highly precise and potent treatments for solid cancers."

"Our first collaboration with Zelluna demonstrated what AI-guided TCR engineering can achieve: a clinically approved receptor in a fraction of conventional timelines. We are excited to apply EMLy again to expand Zelluna’s pipeline and address cancers that desperately need new treatment options" commented Michelle Teng, Founder and CEO of Etcembly.

The poster presentation discloses preclinical data demonstrating that the Company’s best-in-class FAK inhibitor narmafotinib enhances the activity of a new class of drugs called kRAS inhibitors in various models of cancer. In particular, the data indicates that narmafotinib blocks resistance pathways that can emerge with kRAS inhibitor treatment, thereby enhancing efficacy and durability of response.

A copy of the poster is available on the Company’s website.

Inhibitors of mutant kRAS proteins are an exciting new class of drug in development for the treatment of lung, colon and pancreatic cancer, amongst others. There are currently over 50 different kRAS inhibitors undergoing clinical studies across the globe. Despite promising mid-stage clinical data, however, side-effects of these drugs can be significant and treatment-emergent resistance is commonplace.

Dr Chris Burns, CEO of Amplia, commented, "We are excited to present our research findings at this specialist conference focused on RAS inhibition in cancer. We believe there is significant clinical potential in combining narmafotinib with kRAS inhibitors and will be discussing our findings with pharma and biotech companies actively working in this space."

According to data released by GLOBOCAN 2022, in 2022, there were 4.8247 million new cancer cases and 2.5742 million cancer-related deaths in China. Immunotherapy (I-O), represented by anti-PD-1 monoclonal antibodies, has become a cornerstone treatment for various malignant tumors, including lung cancer, breast cancer, liver cancer, esophageal cancer, and nasopharyngeal carcinoma. Now, immunotherapy covers nearly all stages of treatment for cancer patients, encompassing adjuvant/neoadjuvant treatment for early-stage tumors, consolidation treatment after radical chemoradiation for locally advanced tumors, and first-line to last-line treatments for advanced tumors. Currently, most immunotherapy drugs in China are administered intravenously, and this not only requires lengthy infusion times, but also imposes significant inconveniences on patients. There is an urgent clinical need for more convenient administration methods for immunotherapy.

Independently developed by Junshi Biosciences, JS001sc injection is a subcutaneous injection based on the marketed product toripalimab injection (code: JS001) that is expected to enhance convenience for patients. The 12 indications in the JS001sc NDAs cover all currently approved indications of toripalimab injection in the Chinese Mainland.

The NDA is mainly based on the JS001sc-002-III-NSCLC Study (NCT06505837), a multi-center, open-label, randomized phase 3 clinical study led by principal investigator Professor Lin WU from Hunan Cancer Hospital. The study aimed to compare the exposure, efficacy and safety of JS001sc plus chemotherapy versus JS001 plus chemotherapy for the first-line treatment of recurrent or metastatic non-squamous non-small-cell lung cancer ("NSCLC"). The results showed that JS001sc’s exposure was non-inferior to that of JS001 with comparable efficacy and safety profiles. JS001sc-002-III-NSCLC was the first phase 3 clinical study of domestic anti-PD-1 monoclonal antibody in a subcutaneous formulation. Further details will be presented at an upcoming international academic conference.

Professor Lin WU said, "The JS001sc-002-III-NSCLC study, as China’s first Phase 3 clinical trial of a domestically developed PD-1 monoclonal antibody in a subcutaneous formulation, confirmed that the subcutaneous administration method achieved statistical non-inferiority in drug exposure compared with intravenous administration, while demonstrating comparable efficacy and safety. This milestone not only validates the scientific rationale behind the pharmaceutical development of the subcutaneous formulation, but also provides a novel administration pathway for cancer immunotherapy at the clinical level. In the current era of holistic cancer management, treatment convenience and improved quality of life have become critical clinical priorities. The development and application of subcutaneous injection formulations are expected to significantly reduce dosing time, optimize healthcare resource allocation, and offer new technical support for advancing hierarchical medical systems and home-based treatment management. We anticipate the early approval of the subcutaneous formulation of toripalimab, which will further enrich China’s cancer immunotherapy landscape and ultimately benefit a broader population of cancer patients."

Dr. Jianjun ZOU, General Manager and CEO of Junshi Biosciences, said, "We are excited that the NMPA has formally accepted the NDA for JS001sc covering all approved indications of TUOYI (toripalimab). This signifies JS001sc’s potential to address multiple tumor types, including NSCLC, nasopharyngeal carcinoma, esophageal cancer, renal cancer, and liver cancer. It also marks another critical milestone in expanding toripalimab’s innovative and clinical value. As a subcutaneous formulation, JS001sc will substantially enhance dosing convenience, optimize patient treatment experiences, and improve long-term therapy adherence. Moving forward, we will actively advance the regulatory review process, consistently centering patient needs. Using our clinical evidence, we hope to leverage evidence-based medicine to advance high-quality development of China’s cancer therapies, ultimately delivering more accessible, convenient, and high-quality treatment options to patients."
