Trial for Local Ablative Treatment (LAT) Optimization in Patients With Advanced Non-Small Cells Lung Cancer (NSCLC) Presenting an Anaplastic Lymphoma Kinase (ALK) Rearrangement Treated by Brigatinib

Inclusion Criteria

• •Age 18 years or older at diagnosis.
• •Stage 3 non eligible for chemoradiotherapy or stage 4 NSCLC, histologically or cytologically confirmed NSCLC.
• •Tyrosine Kinase Inhibitor (TKI) treatment naïve.
• •ALK rearrangements identified by a validated technique (either Immunohistochimy (IHC), fluorescence in situ hybridization (FISH) or Ribonucleic Acid (RNA)seq, in tissue or liquid biopsy)
• •Stable disease or response after initiation brigatinib treatment (at least 3 to 9 months) according to RECIST 1.1
• •At least one site of residual site for LAT (ie. participant should not have a complete response)
• •Oligometastatic disease (five metastatic lesions or less and a maximum of two lesions per organ) de novo or induced
• •Eligible for local ablative treatment possible (either alone or combined): surgery, minimally invasive form of surgical radiosurgery (Stereotactic Radio Surgery (SRS)) (18 to 20 Gy in single fraction) or radiotherapy (SBRT) (27 to 54 Gy in 3 fractions or 45 to 50 Gy in 5 fractions), radiofrequency or cryotherapy (=thermoablation)
• •An Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤2.
• •Life expectancy above 12 weeks as assessed by treating investigator.
• •Brain metastases at inclusion are allowed if asymptomatic
• •No history of other malignant tumor during the previous 5 years, except for adequately treated carcinomas (in situ cervical carcinoma, basal cell carcinoma, squamous cell skin carcinoma) and low-grade localized prostate cancer (Gleason \<6).
• •Adequate organ function, as demonstrated by laboratory results prior to the first administration of study treatment: normal hepatic function (bilirubin ≤1.5 x upper limit of normal (ULN), alanine aminotransferase (ALA T) and aspartate aminotransferase (ASAT) ≤2.5 x ULN or ≤5 x ULN in case of liver metastases), renal function (calculated creatinine clearance (CrCl, using local formula) above 45 ml/mn), normal hematological function (absolute neutrophil count
• •≥1.5 x 109/L and/or platelets ≥100 x 109/L, hemoglobin ≥8 g/dL), normal coagulation function (International Normalized Ratio (INR) or prothrombin time ≤1.5 x ULN and activated partial thromboplastin time (aPTT) or partial thromboplastin time (PTT) ≤1.5 x ULN unless the patient is receiving anticoagulant therapy)
• •For patients of childbearing potential: Women of childbearing potential should use effective non-hormonal contraception during treatment with brigatinib and for at least 4 months following the final dose. Men with female partners of childbearing potential should use effective contraception during treatment and for at least 3 months after the last dose of brigatinib.
• •Signed informed consent to participate in the study
• •Affiliation with or benefit from French social security
