RAPART in Locally Advanced Non-small Cell Lung Cancer Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Radiosensitivity-Assisted Personalized Adaptive Radiotherapy Technology（RAPART)）: RAPART technology is a special combination of ART and RAPRT, with a total course limit of no more than 30 exposures. The entire course of treatment can be divided into two stages: the first stage is completely the same as the conventional radiotherapy group, with a total of 23 doses of 2 Gy per session. The second stage is the combination of ART and PAPRT. ART uses a CT or PET/CT localization simulation to be performed again during the course of treatment (usually after completing the first part of 17-19 exposures) to generate a new adaptive plan, and after completing the first stage of 23 exposures, treatment is carried out according to the new adaptive plan. RAPAT uses ERCC1/2 biomarkers to predict the patient's radiation sensitivity and determine individualized radiation dose accordingly. ERCC1/2 biomarkers divided patients into 5 different radiosensitivity groups, corresponding to 5 different radiation doses (74, 66, 62, 54, and 50 Gy).

Conventional radiotherapy: conventional radiotherapy

Study summary

This is a Phase II/III randomized clinical trial of Radiosensitivity-Assisted Personalized Adaptive Radiotherapy Technology (RAPART) in locally advanced non-small cell lung cancer patients. The main objective is to test the overall improvement of overall survival (OS), progression free survival (PFS), and local progression free survival (LPFS) of unresectable stage III NSCLC under standard and non-standard mixed treatment conditions compared to conventional 60Gy radiotherapy.

Eligibility

Primary outcome measure(s)

• overall survival — From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months
