Retlirafusp Alfa Combined With Apatinib and Nab-Paclitaxel as Second-line Treatment for Gastric or Gastroesophageal Junction Cancer (RA-A-NP)

25 mei 2026 bijgewerkt door: Henan Cancer Hospital

Retlirafusp Alfa Combined With Apatinib and Nab-Paclitaxel as Second-line Treatment for Patients With Immunotherapy-Pretreated Gastric or Gastroesophageal Junction Cancer: A Prospective, Single-Arm Clinical Study

This is a prospective, single-arm, investigator-initiated phase II clinical study. The study evaluates the efficacy and safety of retlirafusp alfa (a PD-L1/TGF-βRII bifunctional fusion protein) combined with apatinib (a VEGFR-2 tyrosine kinase inhibitor) and nab-paclitaxel in patients with locally advanced unresectable, locally recurrent, or metastatic HER2-negative gastric or gastroesophageal junction adenocarcinoma who have progressed after first-line immunotherapy-containing treatment.

Gedetailleerde beschrijving

Gastric cancer is one of the most common malignant tumors of the digestive system. For patients with advanced gastric cancer who have failed first-line immunotherapy plus chemotherapy, second-line treatment options remain limited. Retlirafusp alfa is a bifunctional fusion protein targeting PD-L1 and TGF-βRII. Apatinib is a small-molecule anti-angiogenic agent. Nab-paclitaxel is a chemotherapeutic agent recommended for second-line treatment of advanced gastric cancer. This prospective, single-arm study investigates the efficacy and safety of this triple combination regimen in immunotherapy-pretreated advanced second-line gastric or gastroesophageal junction adenocarcinoma, to provide a new therapeutic option for these patients.
