Summary

ROS1 rearrangements are present in 1-2% of NSCLC cases and define a distinct molecular subgroup. Like ALK (anaplastic lymphoma kinase) rearrangements in NSCLC, ROS1 fusions confer sensitivity to the inhibitor crizotinib. Crizotinib, which is a tyrosine kinase inhibitor (TKI), has been shown to be effective in tumors in several retrospective studies.

Recently the FDA approved entrectinib for the treatment of patients with ROS1-positive metastatic NSCLC. This indication is based on the results of pooled data from several trials. Together, these studies demonstrate the efficacy for entrectinib across a variety of solid tumor types including NSCLC with ROS1 fusion.

However, despite the efficacy of crizotinib or entrectinib in ROS1-positive NSCLC, patients will develop resistance to these tyrosine kinase inhibitors.

Lorlatinib is a new and potent ROS1 / ALK inhibitor optimized to penetrate the blood-brain barrier. A recent study has investigated the activity of lorlatinib against the crizotinib-resistant ROS1G2032R mutation. In this situation, lorlatinib effectively inhibited the catalytic activity of recombinant ROS1G2032R resulting in an antiproliferative response. Because of its potency as an ROS1 inhibitor and its ability to suppress the resistant ROS1 mutations, lorlatinib could be a treatment of choice in ROS1-positive NSCLC.

Eligibility

Yes No Not Sure

Inclusion Criteria

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 diagnosis of locally advanced not eligible to a local treatment or metastatic NSCLC (Stage IIIB, IIIC or IV accordingly to 8th classification TNM, UICC 2015) that carries an ROS1 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 one prior line of treatment with crizotinib or entrectinib (+ one line of chemotherapy with or without immunotherapy before TKI treatment)
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 crizotinib or entrectinib 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) obtained after progression on crizotinib or entrectinib. 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 45 mL/min as calculated using the method standard for the institution
Adequate Liver Function, including: Total serum bilirubin 1.5 x ULN; 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
For men: agreement to remain abstinent or use an effective method of contraception (e.g., condom) during the treatment period and for at least 14 weeks after the last dose of study drug and agreement to refrain from donating sperm during this same period
Evidence of a personally signed and dated informed consent document indicating that the patient has been informed of all pertinent aspects of the study
Willingness and ability to comply with the study scheduled visits, treatment plans, laboratory tests and other procedure
Participant has national health insurance coverage
Washout period: if previous progression on ROS1-TKI: 7 days from last dose of the drug. The washout period may be shortened to 2 days at investigator discretion
