Iparomlimab and Tuvonralimab (QL1706)

This is a single-center, single-arm, phase 2 clinical study testing a new neoadjuvant (pre-surgery) treatment for patients with locally advanced gastric cancer or gastroesophageal junction (GEJ) cancer. The treatment combines two parts: (1) a novel bispecific immunotherapy drug, iparomlimab and tuvonralimab (Qibain®) , which helps the immune system attack cancer cells by blocking the PD-1 and CTLA-4 pathways; and (2) a standard chemotherapy regimen called nab-P-SOX, made up of nab-paclitaxel, oxaliplatin, and S-1. About 28 adults (aged 18-75) with previously untreated, HER2-negative, locally advanced gastric or GEJ adenocarcinoma (clinical stage cT3-4aN+M0) will receive this combination before their planned surgery. The main goal is to see how well the tumor shrinks, measured by the objective response rate (RECIST v1.1). Secondary goals include the rate of complete response in the removed tumor tissue (pathological complete response), how often the cancer is removed with clear margins (R0 resection), survival outcomes, and the safety of the treatment. All participants will be closely followed to track both benefits and side effects. The study is sponsored by Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, with funding and the study drug provided by Qilu Pharmaceutical Co., Ltd.

The purpose of this study is to evaluate the impact of iparomlimab and tuvonralimab as preoperative neoadjuvant therapy on recurrence-free survival (RFS), along with its potential improvement in overall survival (OS), in patients with resectable hepatocellular carcinoma (HCC) at high risk of recurrence.

The purpose of this study is to learn how well a combination of iparomlimab and tuvonralimab (QL1706), lenvatinib, radiotherapy, and hepatic arterial infusion chemotherapy (HAIC) works and how safe it is for people with hepatocellular carcinoma (HCC) that has grown into the portal vein, forming a portal vein tumor thrombus (PVTT). Participants will receive iparomlimab and tuvonralimab together with lenvatinib, radiotherapy directed at the portal vein tumor thrombus, and HAIC, which delivers chemotherapy directly through the hepatic artery. Researchers will evaluate how long the cancer remains controlled without getting worse, how much the tumors shrink, how long participants survive, and whether the treatment makes surgery possible for some participants. Treatment-related side effects will also be assessed. The study will also explore whether features in tumor tissue and blood are associated with treatment response and may help identify patients who are more likely to benefit from this treatment strategy.
