Activity of Lorlatinib Based on ALK Resistance Mutations Detected on Blood in ALK Positive NSCLC Patients

Study Overview
=================
Brief Summary
-----------------
This study includes patients diagnosed with a metastatic non small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK) translocation. The standard treatment for patients with metastatic non small cell lung cancer with ALK translocation is represented by personalized treatment with drugs called ALK inhibitors. During the treatment with an ALK inhibitor, the tumour can start to grow again, because the tumour adapts to the drug and develops escape mechanisms, becoming resistant. At the tumour cells level, the mechanisms underlying resistance can include the development of other alterations, mainly mutations, including in the ALK gene. The alterations that developed depend on the drug the tumour has been exposed to. The alterations can be identified by analysing tumour tissue obtained through a biopsy, however, repeating a tumour biopsy is difficult and risky and might not be able to provide sufficient tissue for the test. Therefore in the last years, new tests have been developed to identify the mutations in the blood. Lorlatinib is a drug that inhibits ALK and has already been identified to be able to control the tumour growth when ALK mutations are identified and is already approved as standard treatment after progression to a previous treatment with ALK inhibitors. The purpose of this study is to identify which patient populations may benefit most from treatment with lorlatinib, based on the alterations found in their genes.

The patient could be enrolled during the ongoing response to second-generation anaplastic lymphoma kinase (ALK) inhibitor if the following conditions are fulfilled: The patient has received at least 6 months of second generation anaplastic lymphoma kinase - tyrosine kinase inhibitor (ALK-TKI) therapy (if crizotinib-pretreated) OR The patient has received at least 12 months of second generation ALK-TKI therapy (if crizotinib-naïve) Patient is willing and able to comply with the protocol for the duration of the study including scheduled visits and examinations including follow up Before patient registration, written informed consent must be given according to the International Conference on Harmonisation-Good Clinical Practice (ICH/GCP), and national/local regulations B) Enrolment in ALKALINE phase II study. Inclusion criteria Age ≥18 years old Histologically or cytologically confirmed diagnosis of NSCLC with ALK rearrangement, assessed by fluorescence in situ hybridization (FISH) assay (Abbott Molecular Inc) or by Immunohistochemistry (IHC) (Ventana Inc) approved by food and drug administration (FDA) Stage IIIB (not eligible for local therapy) or stage IV (according to Union for International Cancer Control (UICC) tumor lymph node metastasis (TNM) staging v8.0) World health organization (WHO) performance status (WHO PS) of 0-2 Previous treatment with at least one 2nd-generation ALK inhibitor. The 2nd-generation ALK TKI (ceritinib, alectinib, brigatinib) should be the latest therapy. Progressive disease during treatment with 2nd-generation ALK inhibitor prior to the administration of lorlatinib Measurable disease according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 by computed tomography (CT) or magnetic resonance imaging (MRI) of Chest/Abdomen/Pelvis and brain MRI performed within 28 days prior to study enrolment Note: At least one measurable extracranial lesion is required. Archival tissue from primary tumour or metastatic site, if available, and blood samples Note: if blood samples cannot be collected (patient's refusal or any other reason), patient will not be eligible for this study. Treated and/or untreated brain or leptomeningeal metastases will be allowed if asymptomatic and/or controlled (stable dose of steroids 7 days before the beginning of lorlatinib treatment) Adequate bone marrow and organ function defined as following: Absolute Neutrophil Count (ANC) ≥ 1.5 x 10E9/L; Platelets ≥ 100 x 10E9/L; Hemoglobin ≥ 9 g/dL; Serum total amylase ≤1.5 Upper Limit Normal (ULN); Serum lipase ≤1.5 ULN; Serum creatinine ≤1.5 x ULN or estimated creatinine clearance > 30 mL/min - Total serum bilirubin ≤1.5 x ULN or direct bilirubin ≤ ULN for patients with total bilirubin levels > 1.5 x ULN; for patients with Gilbert's disease total bilirubin may be > 1.5 x ULN, however direct bilirubin must be normal; Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≤2.5 x ULN (≤5.0 x ULN if there is liver metastases involvement); Women of child bearing potential (WOCBP) must have a negative serum pregnancy test within 3 days prior to the first dose of lorlatinib. Note: women of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e. females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antioestrogens, low body weight, ovarian suppression or other reasons. Patients of childbearing / reproductive potential should use highly effective birth control measures, as defined by the investigator, during the study treatment period and for at least 5 weeks after the last dose of lorlatinib for female patients and for at least 14 weeks after the last dose of lorlatinib for male patients. A highly effective method of birth control is defined as a method, which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include: Combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal) Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable) Intrauterine device (IUD) Intrauterine hormone-releasing system (IUS) Bilateral tubal occlusion Vasectomized partner Sexual abstinence (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient) Note: Lorlatinib can induce Cytochrome P450 3A4/5 (CYP3A4/5) both in vitro and in vivo. Most hormonal contraceptives are CYP3A substrates, therefore, if this method of contraception is chosen it must be used along with condom (male or female condom) due to the risk of contraception failure. Female subjects who are breast feeding should discontinue nursing prior to the first dose of study treatment and until 7 days after the last dose of lorlatinib. Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up. Before patient registration, written informed consent must be given according to ICH/GCP, and national/local regulations. Exclusion criteria Spinal cord compression. Patients who received adequate treatment (surgery or radiotherapy) and has adequate control of the pain and stabilization and/or recovery of neurological symptoms/function for the 3 weeks prior to study entry are allowed Major surgery within 4 weeks prior to study enrolment. Complete wound healing from major surgery must have occurred 3 weeks before the first dose of study treatment. Minor surgical procedures (including port insertion, uncomplicated tooth extractions) without complete wound healing at the latest 1 week before the first dose of study treatment. Radiation therapy within 2 weeks of study entry. Exception are: Palliative radiation (≤10 fractions) is allowed if completed at least 48 hours prior to study enrolment Stereotactic or small field brain irradiation is allowed if completed at least 2 weeks prior to study enrolment Whole brain radiation is allowed if completed at least 4 weeks prior to study enrolment Any systemic anti-cancer therapy or an investigational drug treatment completed within 5 half-lives prior to start lorlatinib (in case of clinically meaningful risk of tumour flare according to investigator's assessment, discussion with EORTC is required before enrolment) Any unresolved toxicities from prior systemic therapy, including haematological toxicities, greater than International Common Terminology Criteria for Adverse Events (CTCAE) v5.0 grade 2 at the time of study enrolment Active infection requiring therapy Known active hepatitis B (HBV) or hepatitis C (HCV).
