Summary
Lorlatinib is a third-generation, oral, reversible, ATP-competitive, macrocyclic TKI of ALK and ROS1. Lorlatinib was specifically designed to penetrate the CNS and to overcome known secondary resistance mutations in the ALK tyrosine kinase domain.
This is a Phase 4, open-label, multicenter, non-randomized, prospective, single arm study to evaluate the safety and tolerability of lorlatinib in adult participants with unresectable advanced and/or recurrent ALK-positive NSCLC with resistance or intolerance to at least 1 prior ALK inhibitor treatment.
This study is being conducted as a post approval study to fulfill Central Drugs Standard Control Organization (CDSCO) request relating to additional information on use of Lorlatinib in Indian patients.
Eligibility Criteria
Inclusion Criteria
- Evidence of histologically or cytologically confirmed diagnosis of unresectable advanced and/or recurrent NSCLC that carries an ALK rearrangement, as detected by an appropriate test.
- Disease progression or intolerance to 1 previous treatment with ALK TKI. Participants may have also had prior chemotherapy for their advanced and/or recurrent disease.
- Participants with asymptomatic CNS metastases (including participants controlled with stable or decreasing steroid use within the last 2 weeks prior to study enrollment) will be eligible.
- Age ≥18 years.
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2.
- Adequate hematologic and renal function as defined as:
- Absolute neutrophil count (ANC) ≥1,000/mm3;
- Platelets ≥50,000/mm3;
- Hemoglobin ≥8 g/dL;
- Estimated creatinine clearance ≥30 mL/min as calculated using the method standard for the institution.
- Adequate liver function, including:
- Total serum bilirubin ≤1.5 × upper limit of normal (ULN);
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 × ULN (≤5.0 × ULN in case of liver metastases).
- Adequate pancreatic function, including:
- Serum total amylase ≤1.5 × ULN.*
- Serum lipase 1.5 × ULN, but pancreatic amylase is within the ULN, the participant may be enrolled.
- Acute effects of any prior therapy resolved to baseline severity or to CTCAE Grade 25% of the bone marrow.
- Major surgery within 4 weeks prior to enrollment. Minor surgical procedures (eg, port insertion) are not excluded, but sufficient time should have passed for adequate wound healing.
- Known prior or suspected severe hypersensitivity to study drug or any component in its formulation.
- Active and clinically significant bacterial, fungal, or viral infection.
- Clinically significant vascular (both arterial and venous) and non-vascular cardiac conditions (active or within 3 months prior to enrollment), which may include, but are not limited to:
- Arterial disease such as cerebral vascular accident/stroke (including transient ischemic attack [TIA]), myocardial infarction, unstable angina;
- Venous diseases such as cerebral venous thrombosis, symptomatic pulmonary embolism;
- Non-vascular cardiac disease such as congestive heart failure (New York Heart Association Classification Class ≥II), second degree or third degree atrioventricular (AV) block (unless paced) or any AV block with PR interval >220 msec; or ongoing cardiac dysrhythmias of NCI CTCAE Grade ≥2, uncontrolled atrial fibrillation of any grade, bradycardia defined as 470 msec, or congenital long QT syndrome.
- History or known presence of interstitial fibrosis, interstitial lung disease (ILD), pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, obliterative bronchiolitis, and pulmonary fibrosis.
- 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 participant inappropriate for enrollment in this study.
- Evidence of active malignancy (other than current NSCLC, non-melanoma skin cancer, in situ cervical cancer, papillary thyroid cancer, ductal carcinoma in situ [DCIS] of the breast or localized and presumed cured prostate cancer) within the last 3 years prior to enrollment.
- Concurrent use of any of the following food or drugs (consult the Sponsor if in doubt whether a food or a drug falls into any of the categories described below) within 12 days prior to the first dose of lorlatinib:
- Known strong cytochrome (CYP)3A inducers (eg, carbamazepine, enzalutamide, mitotane, rifampin, St. John's Wort).
- Known strong CYP3A inhibitors (eg, grapefruit juice or grapefruit/grapefruit related cit
