Официальное название

Hypofractionated Chemoradiotherapy Followed by Consolidative Immunotherapy Versus Conventional Fractionated Chemoradiotherapy Followed by Consolidative Immunotherapy in Locally Advanced Non-small Cell Lung Cancer: A Randomized, Phase III Controlled Study

Обзор

Consolidative immunotherapy following concurrent chemoradiotherapy, based on the PACIFIC trial, has become the standard treatment for locally advanced non-small cell lung cancer (LANSCLC). Radiotherapy strategies for maximizing efficacy and local control require further investigation. This phase III, randomized controlled clinical trial is to investigate the efficacy and safety of hypofractionated chemoradiotherapy followed by consolidative immunotherapy versus conventional fractionated chemoradiotherapy followed by consolidative immunotherapy in LANSCLC patients.

Подробное описание

This phase III, randomized controlled trial aims to investigate the efficacy and safety of hypofractionated chemoradiotherapy followed by consolidative immunotherapy versus conventional fractionated chemoradiotherapy followed by consolidative immunotherapy in LANSCLC patients. Patients will be randomized in a 2:1 ratio to the following two groups: (1) Study group: Patients in this group will undergo hypofractionated chemoradiotherapy, followed by consolidative immunotherapy for a maximum duration of 12 months. (2) Control group: Patients in this group will receive conventional fractionated chemoradiotherapy followed by consolidative immunotherapy for a maximum duration of 12 months.

Вмешательства

• Лучевая терапия Hypofractionated Radiation Therapy
  All patients will receive split-course hypofractionated radiotherapy. First course of radiotherapy: Total dose of 4000 cGy in 10 daily fractions (400 cGy per fraction) or 3000 cGy in 6 daily fractions (500 cGy per fraction). Three weeks after the completion of the first course of hypofractionated radiotherapy, tumor response and toxicity will be evaluated. For patients who achieve a partial response and without grade 2 or higher respiratory toxicity, a second course of radiotherapy will be plann
• Лучевая терапия Conventionally Fractionated Radiation Therapy
  Patients in this group will receive a total dose of 6000- 6400 cGy in 30- 32 fractions, with 200 cGy per fraction.
• Препарат Concurrent Chemotherapy
  Paclitaxel plus platinum-based chemotherapy.
• Препарат concurrent chemotherapy
  Paclitaxel plus platinum-based chemotherapy or pemetrexed plus platinum-based chemotherapy.
• Препарат Consolidative immunotherapy
  Following the completion of chemoradiotherapy, PD-1/PD-L1 immune checkpoint inhibitor consolidation therapy will be administered for up to 12 months.
