A Clinical Study of QL1706 Combined With Chemotherapy as Neoadjuvant Therapy for High-Risk Locally Advanced Cervical Cancer

Официальное название

A Randomized, Multicenter, Phase III Study of Iparomlimab and Tuvonralimab (QL1706) Combined With Chemotherapy as Neoadjuvant Therapy for Locally Advanced Cervical Cancer

Обзор

This study aims to compare the efficacy and safety of "neoadjuvant immunotherapy combined with chemotherapy followed by immunotherapy combined with radiotherapy during the radiotherapy period" versus "standard concurrent chemoradiotherapy" in locally advanced cervical cancer.

Вмешательства

• Лучевая терапия standard EBRT+Brachytherapy
  EBRT: 45-50.4Gy, Brachytherapy: 6Gy ×5
• Препарат Cisplatin
  Cisplatin 40mg/m2, qw×5
• Препарат Neoadjuvant chemoimmunotherapy
  Neoadjuvant phase: total of 2 cycles. Iparomlimab/Tuvonralimab 5mg/kg,D1,Q3W + albumin paclitaxel 90mg/m2, D1、8、15，Q3W+ Cisplatin 25mg/m2 or Carboplatin AUC = 1.5 , D1、8、15，Q3W
• Лучевая терапия Radiotherapy combined with immunotherapy
  Following neoadjuvant therapy, patients will receive EBRT + QL1706. After EBRT completion, brachytherapy dose is 600 cGy × 3 fractions for patients with clinical complete response (CCR), and 600 cGy × 5 fractions for non-CCR patients.
• Препарат Immunomaintenance therapy
  Iparomlimab/Tuvonralimab (QL1706) 5 mg/kg，D1,Q3W. Will be administered for up to 2 years, until disease progression, or until unacceptable toxicity, whichever occurs first.
