A Multicenter Single-arm Phase II Interventional Study to Evaluate the Activity and Safety of the Combination of Platinum-pemetrexed Based Chemotherapy Plus Lorlatinib in ALK Positive Non-Small Cell Lung Cancer (NSCLC) With Exclusively Extracranial Disease Progression on Lorlatinib.
This study aims to evaluate the activity and safety of the combination of platinum-pemetrexed based chemotherapy plus Lorlatinib in ALK positive Non-Small Cell Lung Cancer (NSCLC) with exclusively extracranial disease progression on Lorlatinib. Platinum-pemetrexed based chemotherapy plus Lorlatinib will be administered for an induction phase of four cycles. Subsequently, patients with response or stability of disease at radiological assessment will start the maintenance phase with pemetrexed-Lorlatinib in 21-day cycles until progression, unacceptable toxicity, death, or withdrawal of consent.
• Histologically or cytologically confirmed diagnosis of stage IV ALK positive NSCLC.
• Patients must be in progression extracranially on Lorlatinib; Lorlatinib may be in first- or further-line, without limitations regarding previously received therapies.
• Age at the time of signing the informed consent at least 18 years.
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
• Patients must have measurable disease according to RECIST 1.1 by computed tomography (CT) and magnetic resonance imaging (MRI).
• Radiologically confirmed multiple extracranial progression on Lorlatinib without progression in the central nervous system (CNS) defined as absence of CNS metastasis or CNS metastasis stable on Lorlatinib and/or stereotactic brain irradiation (SBRT).
• Adequate organ function (kidney, bone marrow and liver).
• Estimated life expectancy of at least 3 months irrespective of the diagnosis of ALK+ NSCLC.
• For women of childbearing potential and males with partners of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of \< 1% per year during the treatment period and for at least 6 months after the last dose of study drugs.
