Outcome Measures
Primary Outcome Measures

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Subjects with histologically or cytologically confirmed diagnosis of locally advanced or metastatic ROS1 gene arrangement positive NSCLC.
-
Subject should have radiological disease progression while on treatment with crizotinib as the only prior ROS1 inhibitor.
-
Subjects must have been treated with platinum-based doublet chemotherapy for locally advanced/metastatic disease for at least one cycle and must have radiological disease progression on or after that.
-
Prior treatment with small molecules or cytotoxic agents must have completed ≥5 half-lives prior to initiating study treatment; Prior treatment with antibodies must have completed at least 3 weeks prior to initiating study treatment.
-
All Subjects must have at least 1 measurable target lesion (intracranial or extracranial) according to RECIST v1.1.
-
Eastern Cooperative Oncology Group performance status (ECOG PS) 0, 1, or 2.
-
Age ≥18 years.
-
Subjects must have adequate organ function as assessed in the laboratory tests.
-
Acute effects of prior radiotherapy and chemotherapy resolved to baseline severity or to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE 5.0) Grade 1 except for AEs that in the investigator's judgment do not constitute a safety risk for the subject.
-
Serum pregnancy test (for females of childbearing potential) negative at screening.
-
Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
-
Willing and able to comply with the study scheduled visits, treatment plans, laboratory tests, and other procedures.
Exclusion Criteria:
-
More than 1 prior chemotherapy regimen prior to enrollment in the locally advanced/metastatic setting.
-
Subject's cancer has a known primary driver alteration other than ROS1 gene rearrangement.
-
Major surgery within 4 weeks prior to the first dose.
-
Radiation therapy within 2 weeks prior to the first dose. Palliative radiation must have been completed at least 48 hours prior to the first dose. Stereotactic or partial brain irradiation must have completed at least 2 weeks prior to the first dose. Whole brain irradiation must have completed at least 4 weeks prior to the first dose.
-
Spinal cord compression unless the subject has good pain control attained through therapy, and there is complete recovery of neurological function for the 4 weeks prior to the first dose.
-
Gastrointestinal abnormalities, including inability to take oral medication; requirement for intravenous alimentation; prior surgical procedures affecting absorption including total gastric resection or lap band; active inflammatory gastrointestinal disease, chronic diarrhea, symptomatic diverticular disease; treatment for active peptic ulcer disease in the past 6 months; malabsorption syndromes.
-
Known prior or suspected severe hypersensitivity to lorlatinib or any component in the formulation; known prior therapy with lorlatinib.
-
Severe acute or chronic infections.
-
Clinically significant cardiovascular disease (both arterial and venous) and non-vascular cardiac conditions (active or within 3 months prior to the first dose).
-
Subject with predisposing characteristics for acute pancreatitis according to investigator judgment, including but not limited to uncontrolled hyperglycemia, current gallstone disease, in the last month prior to the first dose.
-
History of extensive, disseminated, bilateral or presence of Grade 3 or 4 interstitial fibrosis or interstitial lung disease including a history of pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, interstitial lung disease, obliterative bronchiolitis and pulmonary fibrosis.
-
Evidence of active malignancy within the last 3 years prior to the first dose.
-
Concurrent use of any of the prohibited food or drugs required in protocol within 12 days prior to the first dose of administration of lorlatinib.
-
Other severe acute or chronic medical or psychiatric condition, 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, would make the subject inappropriate for entry into this study.
-
Participation in other studies involving investigational drug(s) within 2 weeks prior to study entry and/or during study participation.
-
Pregnant female subjects; breastfeeding female subjects.
