Iparomlimab and Tuvonralimab (QL1706) Combined With Standard Chemotherapy or Combined With Intraperitoneal Perfusion Chemotherapy and Olaparib as Neoadjuvant Therapy for Advanced Ovarian Cancer

This study is a prospective, open-label, multicenter Phase II clinical trial, planning to enroll 50 patients with advanced ovarian cancer. Enrolled participants will be assigned to 2 cohorts based on ECOG performance status and genetic mutation status: Cohort 1: ECOG PS 0 or 1, all-comers population, regardless of BRCA or HRD test results. Treatment: iparomlimab and tuvonralimab (5 mg/kg, Q3W, D1) + paclitaxel (175 mg/m², Q3W, D1) + carboplatin (AUC 5-6, Q3W, D1)/cisplatin (75 mg/m², Q3W, D1). Planned enrollment: 30 patients. Cohort 2: ECOG PS 2, BRCA1/2 mutation or HRD positive. Treatment: iparomlimab and tuvonralimab (5 mg/kg, Q3W, D1) + olaparib (300 mg, for 2-3 cycles, bid) + intraperitoneal perfusion (cisplatin, 75 mg/m², Q3W, D1). Planned enrollment: 20 patients. Neoadjuvant therapy will be administered for 3 cycles, followed by patient status assessment. Patients with CR/PR/SD will be allowed to undergo surgery, while PD patients will have subsequent treatment strategies determined by the investigator.

Study to Evaluate the Diagnostic Performance of GEH300079 (68Ga) Injection PET/CT for Detection of PC in Patients With Colorectal, Gastric, Ovarian, or Pancreatic Cancers (PERISCOPE)

This study is a Phase 2/3, prospective, multicenter, open-label, non-randomized clinical trial, in which GEH300079 (68Ga) PET/CT images will be acquired in patients with primary colorectal, gastric, ovarian, or Pancreatic Ductal Adenocarcinoma (PDAC) cancers and known or suspected Peritoneal Carcinomatosis (PC) before or after institutional Standard of Care (SoC) imaging. The primary objective is to evaluate the diagnostic performance of GEH300079 (68Ga) PET/CT for the detection of PC in patients with colorectal, gastric, or ovarian primary cancers, using a composite standard of truth (SoT), in a region-based analysis. The detection of PC in patients with primary PDAC will be explored in the Phase 2 part of the study. The study is comprised of 2 distinct parts: Phase 2 aims to confirm the statistical and scientific assumptions for the Phase 3 part, and to confirm the optimal dose and timing of acquisition of GEH300079 (68Ga) PET/CT in the PC indication. Phase 2 includes 2 cohorts: Cohort A (participants with colorectal, ovarian and gastric primary cancer), and Cohort B (participants with primary PDAC), where analysis of Cohort B is descriptive only. Phase 3 aims to demonstrate the safety and efficacy of GEH300079 (68Ga) PET/CT for the detection of PC in patients with confirmed colorectal, gastric or ovarian primary cancers.

Allogeneic B7H3 CAR-γδT Cell Therapy for Advanced Solid Tumors

γδT cells can directly recognize non-peptide tumor antigens, such as IPP phosphorylated metabolites, without relying on specific major histocompatibility complexes (MHCs). This unique characteristic leads to a lower risk of graft-versus-host disease (GVHD). The clinical safety of γδT cells in allogeneic tumor therapies has been validated multiple times, highlighting their significant potential in developing universal CAR-T cell therapies. B7H3 (CD276), a member of the B7 negative co-stimulatory molecule family, is minimally expressed or absent in normal tissues but highly expressed in various tumor tissues. As a result, B7H3 is regarded as a highly promising tumor-associated antigen and a universal drug target with substantial therapeutic potential. By utilizing γδT cells as carrier cells, the development of universal B7H3 CAR-γδT cell injections for advanced solid tumors can effectively address risks such as autologous cell preparation failure and treatment delays. This innovative approach offers a highly efficient solution for solid tumor treatment and holds great promise for advancing immunotherapy in this field
