LDK378 in Adult Chinese Patients With ALK-rearranged (ALK-positive) Advanced Non-small Cell Lung Cancer (NSCLC) Previously Treated With Crizotinib

A single-Arm, open-label, multi-center, phase I/II study in which the pharmacokinetics, safety, tolerability and efficacy of LDK378 will be assessed in adult Chinese patients with locally advanced or metastatic NSCLC harboring a confirmed ALK rearrangement. Patients must have demonstrated progression during or after crizotinib treatment whether or not previously treated with cytotoxic chemotherapy. Approximately 100 patients will be enrolled. For the first 15 patients enrolled in this study, patients will have an additional 5-day PK run-in period before treatment period. The pharmacokinetics profile of LDK378 in Chinese adult patients with ALK-rearranged NSCLC will be evaluated.

This is a phase I/II, open-label, multi-center study in which the PK, safety, tolerability and efficacy of LDK378 will be assessed in adult Chinese patients with locally advanced or metastatic NSCLC harboring a confirmed ALK rearrangement (positive) as assessed using the Vysis ALK Break Apart FISH Probe Kit (Abbott Molecular Inc.) or positive as assessed by immunohistochemistry (IHC) test (Ventana Medical Systems, Inc) using rabbit monoclonal primary antibody assay (D5F3).

Patients must have demonstrated progression during or after crizotinib treatment whether or not previously treated with cytotoxic chemotherapy.

Approximately 100 patients with locally advanced or metastatic NSCLC which carry ALK -rearrangement will be enrolled in the study. The first 15 patients to be enrolled in the study will have PK sampling over 120-hour during the 5-day PK run-in period following a single oral dose at 750 mg. After the PK run-in period, the treatment period will start in which LDK378 will be given starting on Cycle 1 Day 1 in a continuous daily oral dosing in 28-day cycles. Separated from these 15 patients, the rest of the enrolled patients will receive LDK378 treatment at 750 mg QD on Cycle 1 Day 1.

Tumor response will be evaluated every 8 weeks (i.e. every 2 cycles) starting from the first day of treatment with LDK378 until the time of RECIST-defined PD by investigator assessment, withdrawal of consent for further follow-up, loss to follow-up or death.

Eligibility Criteria:
Inclusion criteria:

* Histologically or cytologically confirmed diagnosis of NSCLC that carries an ALK rearrangement defined as positive using the FDA approved Vysis ALK Break Apart FISH Probe Kit (Abbott Molecular Inc.) test and scoring algorithm (including positivity criteria) or positive as assessed by the CFDA approved immunohistochemistry (IHC) test (Ventana Medical Systems, Inc)
* Age 18 years or older at the time of informed consent.
* Patients must have stage IIIB or IV NSCLC at the time of study entry and have had progressive disease during or after crizotinib treatment whether or not previously treated with cytotoxic chemotherapy. If treated with chemotherapy, maximum 2 lines are allowed.

Exclusion Criteria:

* Patients with known hypersensitivity to any of the excipients of LDK378
* Patients with symptomatic central nervous system (CNS) metastases who are neurologically unstable or have required increasing doses of steroids within the 2 weeks prior to study entry to manage CNS symptoms
* History of carcinomatous meningitis
* Presence or history of a malignant disease other than NSCLC that has been diagnosed and/or required therapy within the past 3 years.
* clinically significant, uncontrolled heart disease.
