1. Absolute neutrophil count ≥1.5 x 109/L without growth factor support
2. Platelets ≥100 x 109/L
3. Hemoglobin ≥9 g/dL
4. Calculated creatinine clearance (using Cockcroft-Gault formula) ≥45 mL/min
5. Total bilirubin ≤1.5 ULN (upper limit of normal) (except in patients with Gilbert's syndrome, who may be included if total bilirubin is ≤3.0 x ULN and direct bilirubin is ≤1.5 x ULN))
6. AST ≤3 x ULN, except for patients with liver metastasis, who may only be included if AST ≤5 x ULN
7. ALT ≤3 x ULN, except for patients with liver metastasis, who may only be included if ALT ≤5 x ULN
8. Alkaline phosphatase (ALP) ≤5.0 x ULN
9. Asymptomatic serum amylase ≤ grade 2. Patients with grade 1 or grade 2 serum amylase at the beginning of the study must be confirmed to have no signs and/or symptoms suggesting pancreatitis or pancreatic injury (e.g., elevated P-amylase, abnormal imaging findings of pancreas, etc.)
10. Serum lipase ≤ ULN
8. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 2.
9. Willing and able to comply with scheduled visits, treatment plan, and laboratory tests.
Exclusion criteria
1. Prior treatment with any MET inhibitor or hepatocyte growth factor targeting therapy.
2. Presence or history of a malignant disease other than NSCLC that has been diagnosed and/or required therapy within the past 3 years. Exceptions to this exclusion include the following: completely resected basal cell and squamous cell skin cancers and completely resected carcinoma in situ of any type.
3. 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.
4. Patients with known druggable molecular alterations (such as ROS1 translocation or BRAF mutation, etc.) which might be a candidate for alternative targeted therapies as applicable per local regulations and treatment guidelines.
5. Presence or history of interstitial lung disease or interstitial pneumonitis, including clinically significant radiation pneumonitis (i.e., affecting activities of daily living or requiring therapeutic intervention).
6. Patient with clinically significant heart diseases like unstable angina/acute myocardial infraction within 6 months prior to screening, NYHA class III-IV congestive cardiac failure, uncontrolled hypertension, arrhythmias or QTcF ≥470 ms on the screening ECG.
7. Major surgery (e.g., intra-thoracic, intra-abdominal or intra-pelvic) within 4 weeks prior (2 weeks for resection of brain metastases) to starting Capmatinib or who have not recovered from side effects of such procedure. Video-assisted thoracic surgery and mediastinoscopy will not be counted as major surgery and patients can be enrolled in the program ≥1 week after the procedure.
8. Thoracic radiotherapy to lung fields ≤4 weeks prior to starting Capmatinib or patients who have not recovered from radiotherapy-related toxicities. For all other anatomic sites (including radiotherapy to thoracic vertebrae and ribs), radiotherapy ≤2 weeks prior to starting Capmatinib or patients who have not recovered from radiotherapy-related toxicities. Palliative radiotherapy for bone lesions ≤2 weeks prior to starting Capmatinib is allowed.
9. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of Capmatinib or patients who are unable to swallow oral tablets.
10. Patients receiving treatment with strong inducers of CYP3A that cannot be discontinued at least 1 week prior to the start of treatment with Capmatinib and for the duration of the study.
11. Unable or unwilling to swallow tablets as per dosing schedule.
12. Patients with known hypersensitivity to Capmatinib and any of the excipients of Capmatinib.
13. Patients with any other severe, acute or chronic medical or psychotic conditions or significant abnormal physical findings that in the opinion of the investigator may increase the risk associated with study participation or that may interfere with the interpretation of study results.
14. Patients with prior systemic anti-cancer (chemotherapy, immunotherapy, biologic therapy, vaccine) and investigational agents within 4 weeks or ≤5 x half-life of the agent (whichever is shorter) before the first dose of Capmatinib. If previous treatment is a monoclonal antibody, then the treatment must be discontinued at least 4 weeks before first dose of Capmatinib. If previous treatment is an oral targeted agent, then the treatment must be discontinued at least 5 times the half-life of the agent.
15. Pregnant or nursing (lactating) women.
16. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and for 7 days after stopping study treatment. Highly effective contraception methods include:
1. Total abstinence (when this is in line with the preferred and usual lifestyle of the patient). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
2. Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or bilateral tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment.
3. Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient.
4. Use of oral (estrogen and progesterone), injected, or implanted hormonal methods of contraception or placement of an intrauterine device or intrauterine system, or other forms of hormonal contraception that have comparable efficacy (failure rate \<1%), for example hormone vaginal ring or transdermal hormone contraception. In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking treatment.
17. Sexually active males unwilling to use a condom during intercourse while taking study treatment and for 7 days after stopping study treatment. A condom is required for all sexually active male patients to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to their partner. In addition, male patients must not donate sperm for the time period specified above.
18. Any other condition that would, in the Investigator's judgment, contraindicate patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., active infection (including active hepatitis B and C, SARS-CoV-2), inflammation, intestinal obstruction, unable to swallow medication, social/psychological issues, etc
