Lorlatinib After Failure of First-line Second-generation ALK Kinase Inhibitor in Patients With Advanced ALK-positive Non-small Cell Lung Cancer

Prior treatment

• Participants with disease progression on front-line treatment with 2G ALK-TKI i.e. brigatinib or alectinib limited to CNS or one non-CNS site (oligometastasis) and eligible to a local ablative treatment (surgery or stereotaxic radiotherapy).
• Spinal cord compression is excluded unless the patient demonstrates good pain control attained through therapy and there is stabilization or recovery of neurological function for the 4 weeks prior to study entry.
• Patients with symptomatic and neurologically instable CNS metastases or leptomeningeal metastasis (including patients that require increasing doses of steroids within one week prior to Day 0 of screening phase and during the screening phase to manage CNS symptoms).
• Major surgery within 35 days of study entry. Minor surgical procedures (eg, port insertion, mediastinoscopy, surgical procedure for re-sampling) are not excluded, but sufficient time at investigator discretion should have passed for wound healing.
• Radiation therapy within 2 weeks of study entry (except palliative to relieve bone pain). Palliative radiation (≤15 fractions) must have been completed at least 48 hours prior to study entry. Stereotactic or small field brain irradiation must have completed at least 2 weeks prior to study entry. Whole brain radiation must have completed at least 4 weeks prior to study entry.
• Prior therapy with an antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways, including, but not limited to, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4.
• Clinically significant cardiovascular disease (that is, active or \<3 months prior to enrollment): cerebral vascular accident/stroke, myocardial infarction, unstable angina, congestive heart failure (New York Heart Association Classification Class ≥ II), second-degree or third-degree AV block (unless paced) or any AV block with PR \>220 msec.
• History of bilateral or Grade 3 or 4 interstitial fibrosis or diffuse interstitial lung disease. Patients with history of prior radiation pneumonitis are not excluded.
• Active inflammatory gastrointestinal disease, chronic diarrhea, symptomatic diverticular disease or previous gastric resection or lap band.
• Current use or anticipated need for food or drugs prohibited (see chapter 8.9.2 for details).

Other illness

• Transdifferentiation into small cell lung cancer.
• Active and clinically significant bacterial, fungal, or viral infection including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome (AIDS)-related illness.
• Patients with predisposing characteristics for acute pancreatitis according to investigator judgment (eg, uncontrolled hyperglycemia, current gallstone disease, alcoholism \[more than 4 drinks on any day or 14 drinks per week where 1 drink is defined as the alcoholic beverage containing approximately 14 grams of pure alcohol, eg, 12 fl oz/360 mL regular beer or 5 fl oz/150 mL of wine\] in the last month.
• Evidence of active malignancy (other than current NSCLC, non-melanoma skin cancer, in situ cervical cancer, papillary thyroid cancer, DCIS of the breast or localized and presumed cured prostate cancer) within the last 3 years.

Lab values

• Ongoing cardiac dysrhythmias of NCI CTCAE Grade ≥2, uncontrolled atrial fibrillation of any grade, bradycardia defined as \<50 bpm (unless patient is otherwise healthy such as long-distance runners, athletic patients etc.), machine-read ECG with QTc \>470 msec, or congenital long QT syndrome.
• Other severe acute or chronic medical or psychiatric condition, including recent (within the past year) or active suicidal ideation or behavior, or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
• Patients presenting with abnormal Left Ventricular Ejection Fraction (LVEF) by echocardiogram or Multi-Gated Acquisition Scan (MUGA) according to institutional lower limits.

Other

• Patients who experienced a clinical benefit of less than 6 months with front-line alectinib or brigatinib.
• Breastfeeding female patients (including patients who intend to interrupt breastfeeding).

• Signed Written Informed Consent:
  • Subjects must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care.
  • Subjects must be willing and able to comply with scheduled visits, treatment schedule, and laboratory testing
• Patients with histologically or cytologically confirmed locally advanced not eligible to a local treatment or metastatic NSCLC (Stage IIIB or IV accordingly to 8th classification TNM, UICC 2015) that carries an ALK rearrangement, as determined by the molecular biology platform of the investigator by FISH assay or by Immunohistochemistry (IHC), or Next Generation Sequencing (NGS) or RNA sequencing approach .
• Disease Status Requirements: Disease progression meeting RECISTv1.1 after first-line alectinib or brigatinib only. No prior chemotherapy is allowed in the metastatic disease setting.
• Tumor Requirements: All Patients must have at least one measurable target lesion according to RECIST v1.1. In addition, patients with asymptomatic and neurologically stable CNS metastases (including patients controlled with stable or decreasing steroid use within the last week prior to study entry) will be eligible. The brain metastases may be newly diagnosed after disease progression with alectinib or brigatinib or be present as progressive disease after surgery, whole brain radiotherapy or stereotactic radiosurgery (see Exclusion Criterion for the lapsed time period required between the end of radiotherapy and study entry). Patients who have leptomeningeal disease (LM) or carcinomatous meningitis (CM) will be eligible if the LM/CM is visualized on MRI or if documented baseline cerebral spinal fluid (CSF) positive cytology is available and asymptomatic and neurologically stable (including patients controlled with stable or decreasing steroid use within the last week prior to study entry).
• Tumor Sample Requirement: Tumour biopsy sampling on fresh tissue (FFPE blocks required) at time of progression on first-line TKI is mandatory. Tumour biopsy should be exploitable for molecular analysis. If the tumour biopsy is not exploitable, the inclusion will be allowed if two blood samples are provided for tumoral cfDNA analysis. The Sponsor will monitor a posteriori the exploitability of provided tumour biopsies and will investigate the impossibility to perform or repeat tissue tumor sampling.
• Age ≥18 years.
• Life expectancy of at least 12 weeks, in the opinion of the Investigator.
• Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≤ 2
• Adequate Bone Marrow Function, including:
  • Absolute Neutrophil Count (ANC) ≥1.5 x 109/L;
  • Platelets ≥100 x 109/L;
  • Hemoglobin ≥9 g/dL.
• Adequate Pancreatic Function, including:
  • Serum lipase ≤1.5 x ULN.
• Adequate Renal Function, including:
  • Serum creatinine ≤1.5 x ULN or estimated creatinine clearance ≥60 mL/min as calculated using the method standard for the institution.
• Adequate Liver Function, including:

  • Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≤2.5 x ULN; ≤5.0 x ULN if there is liver metastases involvement.
• Participants must have recovered from treatment toxicities to CTCAE Grade ≤ 1 (for participants who have developed interstitial lung disease \[ILD\], they must have fully recovered) except for AEs that in the investigator' judgment do not constitute a safety risk for the patient.
• Participants must have recovered from effects of any major surgery, or significant traumatic injury, at least 35 days before the first dose of lorlatinib
• For all females of childbearing potential, a negative pregnancy test must be obtained within the screening period. A patient is of childbearing potential if, in the opinion of the investigator, she is biologically capable of having children and is sexually active. Additionally, all females of childbearing potential must provide an agreement to remain abstinent or use two adequate methods of contraception, including at least one method with a failure rate of \< 1% per year, during the treatment period and for at least 90 days after the last dose of study drug.
