Brief Summary

This is single-arm, open-label study design. Patients will receive brigatinib until disease progression, unacceptable toxicity, withdrawal of consent, of death.

Detailed Description

Based on the clinical efficacy of ALK inhibitors in ALK+NSCLC, NCCN guidelines recommend ALK molecular testing of lung cancer patients, to select patients for ALK-targeted therapy. However, molecular testing via tissue biopsy cannot always be performed on NSCLC patients, potentially limiting access of effective treatment to the subset of patients who are able to undergo current testing procedures that utilize tissue biopsies. Obtaining an adequate tissue biopsy specimen for NSCLC presents a number of challenges. In particular, the method for diagnosis of lung cancer depends on the location, size, and type of suspected lung cancer, and the presence or absence of metastases. Common procedures for centrally located tumors include bronchoscopy and sputum cytology, which frequently yield insufficient tumor tissue for comprehensive mutation testing. In addition, 75% of patients are diagnosed with late-stage disease and often present with multiple comorbidities. Biopsies in these patients can lead to complications such as pneumothorax, hemoptysis, other bleeding complications, and cardiopulmonary decompensation. As a result of these factors, a physician treating a patient who presents with a significant burden of disease as well as significant comorbidities may rightly consider whether it is in the best interest of the patient to undergo a risky and potentially unsuccessful procedure. Thus, there exists a major unmet clinical need for testing procedures that do not require tumor tissue. The purpose of this phase II study is to assess the efficacy of brigatinib in patients with advanced NSCLC harboring ALK rearrangement that are selected using predictive biomarkers identified via blood-based assays.

Patients who have disease progression with prior one ALK-TKI treatment for inoperable Stage III (locally advanced) or metastatic ALK+ NSCLC.(Previous treatment only allowed one ALK-inhibitor) Patients who have received prior neo-adjuvant, adjuvant chemotherapy, radiotherapy, or chemoradiotherapy with curative intent for non-metastatic disease must have experienced a treatment-free interval of at least 6 months since the last chemotherapy, radiotherapy, or chemoradiotherapy cycle.

3. ALK rearrangement , as detected via the blood somatic mutation assay

4. One prior ALK inhibitor therapy

5. Have at least 1 measurable lesion per RECIST version 1.1

6. Have Eastern Cooperative Oncology Group (ECOG) performance status 0-2

7. Recovered from toxicities related to prior anticancer therapy to NCI CTCAE, version 5.0, Grade≤1(Note : Alopecia, sensory neuropathy Grade≤2, or other Grade≤2 AEs not constituting a safety risk based on Investigator's judgement are acceptable

8. Have a life expectancy of ≥3 months

9. Have adequate organ and hematologic function as determined by:

1. ALT/AST≤2.5×ULN; ≤5×ULN is acceptable if liver metastases are present

2. Total serum bilirubin≤1.5×ULN (<3.0×ULN for patients with Gilbert syndrome)

3. Estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2, using the MDRD equation

4. Absolute neutrophil count ≥1.5×109/L.

5. Platelet count ≥75×109/L.

6. Hemoglobin ≥9 g/dL.

7. Serum lipase ≤1.5×ULN

10. For female patients of childbearing potential, have a negative pregnancy test(urine or serum) documented ≤3 days before start of study medication.

non-childbearing potential which is defined as :

• female patient≥45 years of age and has not had menses for greater than 1 year
• a female who is status post hysterectomy, oophorectomy

11. Female patients of childbearing potential and male patients with partners of childbearing potential must agree to use 2 effective methods of contraception, at the same time, from the time of signing the informed consent through 4 months after the last dose of study drug, or agree to completely abstain from heterosexual intercourseHave the willingness and ability to comply with scheduled visit and study procedures.

Male patients, even if surgically sterilized (i.e., status post-vasectomy), who:

• Agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug, or
• Agree to completely abstain from heterosexual intercourse

12. Have the willingness and ability to comply with scheduled visit and study procedures.

13. Be ≥ 18 years of age

Exclusion Criteria

1. Has received ALK-targeted TKI within 7 days before the first dose of study treatment(If clinically justified, 3 days wash-out period could be allowed).

2. Has received radiotherapy within 14 days before the first dose of study treatment except for stereotactic radiosurgery (SRS) or stereotactic body radiation therapy (SBRT). A 1-week washout is permitted for palliative radiation(≤2 weeks of radiotherapy) to non-CNS disease.

3. Had major surgery within 28 days of the first dose of study treatment. Minor surgical procedures are allowed.

4. Has symptomatic brain metastasis or leptomeningeal disease.
