Alectinib Followed by Concomitant Consolidation Radiation Therapy in Advanced NSCLC With ALK-rearrangement (A-SAB)

Recruiting now · Not applicable

Conditions studied: Radiotherapy Side Effect, Non-small Cell Lung Cancer, ALK Gene Mutation

In brief

The goal of this clinical trial is to learn evaluate the safety and efficacy of the addition of radiation therapy to all tumour lesions, to first line medical treatment with alectinib in non-small cell lung cancer harbouring ALK-rearrangements. The main aims of the trial are to evaluate: * if the treatment combination is safe * if the treatment combination can inhibit progression Participants who have responded to 1st line alectinib will be treated with consolidation radiation therapy to all remaining tumour lesions while continuing on alectinib until disease progression, unacceptable toxicity or another discontinuation criterion is met.

• Persistent malignant pleural effusion, malignant pericardial effusion or malignant ascites after induction treatment
• PD after 2-3-month-induction treatment with alectinib
• Previous TKI, chemotherapy or immunotherapy (previous adjuvant chemotherapy for early stage NSCLC is allowed) for metastatic NSCLC
• Previous RT for NSCLC (any stage)
• Previous RT for any other cancer within the last 3 years possibly interfering with the planned RT within this study
• Life expectancy of less than 6 months
• Inability to understand given information or undergo study procedures according to protocol.
• Has evidence or a past medical history of interstitial lung disease or active, non-infectious pneumonitis or known pulmonary fibrosis.
