Adjuvant Chemotherapy +/- Cemiplimab and Sequential Hypofractionated Radiotherapy in Unfit or Elderly Patients With Stage III Lung Cancer

Official title

A Multicenter Randomized Open Label Phase II Study Evaluating the Efficacy and the Tolerance of Immunochemotherapy and of Sequential Hypofractionated Radiotherapy in Unfit or Elderly Patients With Unresectable Stage III Non Small Cell Lung Cancer

Overview

The use of neoadjuvant immuno-chemotherapy could improve survival outcomes of patients eligible for sequential radio-chemotherapy comparing to the benefit already obtained with maintenance immunotherapy.

Interventions

• Drug Carboplatin
  Neoadjuvant treatment with Carboplatin AUC 5 D1 (3 cycles of 4 weeks).
• Drug Paclitaxel
  Neoadjuvant treatment with Paclitaxel 80mg/m² D1 (3 cycles of 4 weeks).
• Drug Cemiplimab
  Neoadjuvant treatment with Cemiplimab (Libtayo®) 350 mg D1-D21 (3 cycles of 4 weeks).
• Radiation Curative hypofractionated radiotherapy
  Curative hypofractionated radiotherapy (55 Gy/20fr) after the end of neoadjuvant treatment.
• Drug Cemiplimab (maintenance)
  Maintenance immunotherapy with Cemiplimab 350 mg every 3 weeks after the end of radiotherapy (12 months).

• PFS at 12 months [Time frame: At 12 months]
• PFS at 18 months [Time frame: At 18 months]
• PFS at 3 year [Time frame: At 3 year]
• Overall Survival (OS) curve [Time frame: About 3 year]
• OS at 12 months [Time frame: At 12 months]
• OS at 18 months [Time frame: At 18 months]
• OS at 3 year [Time frame: At 3 year]
• Acute and late grade 3-4 toxicity rates of neoadjuvant chemoimmunotherapy before hypofractionated radiotherapy [Time frame: Up to 90 days after the end of immunotherapy]
• To evaluate the quality of life of patients receiving neoadjuvant chemoimmunotherapy before hypofractionated radiotherapy with questionnaire EORTC Quality of Life Questionnaire - Core C30 (QLQ-C30) [Time frame: About 18 months]
• To evaluate the quality of life of patients receiving neoadjuvant chemoimmunotherapy before hypofractionated radiotherapy with questionnaire EORTC Quality of Life Questionnaire - Lung Cancer LC29 (QLQ-LC29). [Time frame: About 18 months]
