Volunteers
Inclusion criteria
Male or female ≥ 18 years of age or designated age of majority according to the regulatory authorities, whichever is higher.
Eastern Cooperative Oncology Group (ECOG) performance status (PS), 0 or 1.
Have a life expectancy of at least 3 months.
Diagnosis:
must have histologically or cytologically confirmed NSCLC, advanced, recurrent, or metastatic,
For Cohort 1: MET exon 14 skipping suspected by local or central biomarker assessment. [local testing is accepted for eligibility; all patients will have confirmation by central laboratory, but this result is not necessary for eligibility; local molecular pathology result will suffice]. This testing can be from archival or fresh tissue sample and/or blood specimen; any sample, any test positive subjects are eligible.
For Cohort 2:
Treatment experience
At least one measurable lesion per response evaluation criteria in solid tumors (RECIST) 1.1
While on study treatment and for 6 months after the last dose of study treatment, a patient must:
i. Have a negative highly sensitive (eg, beta-human chorionic gonadotropin [β-hCG]) pregnancy test at screening and within 72 hours before the first dose of study treatment, and agree to further pregnancy tests, ii. Practice at least 1 highly effective method of contraception; if oral contraceptives are used, a barrier method of contraception must also be used.
e. If a patient's partner is of childbearing potential, the participant must use a condom and partner of the participant must also be practicing a highly effective method of contraception. A vasectomized patient must still use a condom, but the partner is not required to use contraception.
Resolution of prior-therapy-related AEs (including immune-related AEs but excluding alopecia) to ≤ Grade 1 per CTCAE v 5.0, and no treatment for these AEs for at least 2 weeks prior to the time of enrollment. Alopecia, sensory neuropathy Grade ≤ 2, or other Grade ≤ 2 AEs not constituting a safety risk based on investigator's judgment are acceptable.
Adequate organ function as indicated by laboratory values.
Submit tissue and blood specimens.
Cohort 1:
All patients should submit tumor tissue/block collected from fresh biopsy or have available archival formalin-fixed, paraffin-embedded tumor tissue specimen. The archival tissue must be:
For fresh biopsied sample, core needle biopsy is permitted. Samples from fine-needle aspiration (FNA) is not acceptable unless the result of MET exon 14 skipping from local testing is available.
All patients must submit blood samples.
Cohort 2:
Exclusion criteria
Previous severe hypersensitivity reaction to any component of study drug(s).
Prior therapy
a. Previous treatment with c-MET inhibitors or hepatocyte growth factor (HGF)-targeting therapy.
b. For Cohort 2, prior chemotherapy for advanced, recurrent, or metastatic setting.
Genetic analysis results:
Chronic inflammatory liver condition. History or clinical evidence of any significant liver or biliary pathology including cirrhosis, infectious disease, inflammatory conditions, steatosis, or cholangitis (including ascending cholangitis, primary sclerosing cholangitis, obstruction, perforation, fistula of biliary tract, spasm of sphincter of Oddi, biliary cyst or biliary atresia).
Past medical history of Interstitial Lung Disease (ILD)/pneumonitis, drug-induced or radiation ILD/pneumonitis that required steroid treatment or other immune suppressive agents, or evidence of current symptomatic interstitial lung disease or unexplained pulmonary symptoms indicative of ILD such dyspnea, cough, or fever.
Impairment of Gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drugs (e.g., ulcerative diseases, uncontrolled nausea, uncontrolled vomiting, uncontrolled diarrhea, or malabsorption syndrome)
Prior organ or stem cell transplant.
Known active infection with human immunodeficiency virus (HIV), human T-cell leukemia virus, type (HTLV-1), hepatitis B virus (HBV), or hepatitis C virus (HCV), unless the patients fall into below categories (patients fall into one of the a, b, c category are eligible to participate)
HIV
✓ CD4+ cells ≥ 350 cells/µL
✓ No history of AIDS
✓ No history of opportunistic infection in the past 12 months
HCV
✓ Undetectable viral load (Participants positive for hepatitis C antibody are eligible only if polymerase chain reaction is negative for hepatitis C RNA)
HBV ✓ Concurrent HBV treatment and undetectable viral load (Participants with a past or resolved hepatitis B infection defined as the presence of hepatitis B core antibody [anti-HBc] and absence of hepatitis B surface antigen are eligible)
Symptomatic ascites or pleural effusion, unless clinically stable for at least two weeks following treatment for these conditions (including therapeutic thoraco- or paracentesis).
Known active central nervous system (CNS) primary tumor or metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are clinically stable for at least 4 weeks prior to first dose of study medication(s), have no evidence of new or enlarging brain metastases and are off steroids for at least 15 days prior to first dose of study medication(s).
Presence or history of a malignant disease other than disease to be treated in current protocol 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, indolent malignancies that currently do not require treatment, and completely resected carcinoma in situ of any type.
Active infection requiring therapy. However, subject with minor infections requiring oral antibiotics, (e.g., urinary tract infection, Upper respiratory tract infection, etc.) could be eligible based on investigator's judgement.
Use of systemic corticosteroids > 10 mg/day prednisone or equivalent within 30 days or other immunosuppressive drugs within 30 days prior to first drug administration.
Patients receiving treatment with medications that meet one of the following criteria and that cannot be discontinued specified period prior to the start of treatment with study drug and for the duration of the study.
For Vabametkib (Wash-out: 1 week)
• Strong and moderate inhibitors/inducers of P-glycoprotein
• Strong and moderate inhibitors/inducers of CYP3A4
• Proton pump inhibitors (PPI)
• Potassium-competitive acid blockers For Lazertinib
Has received or will receive a live vaccine within 30 days prior to the first administration of study medication. Seasonal flu vaccine that does not contain live vaccine are permitted.
Received an investigational product (except for EGFR TKI in Cohort 2) or treated with an investigational device within 30 days prior to first study drug administration.
Has been receiving: radiotherapy, chemotherapy, or molecularly-targeted agents or tyrosine kinase inhibitors (except for EGFR TKI in Cohort 2) within 2 weeks (4 weeks in case of thoracic radiotherapy to lung fields) or 5 half-lives (whichever is longer) of the start of study treatment; immunotherapy/monoclonal antibodies within 3 weeks of the start of study treatment; nitrosoureas, antibody-drug conjugates, or radioactive isotopes within 6 weeks of the start of study treatment; 7-day washout is permitted for palliative radiation (i.e. limited field, ≤ 14-day course of radiotherapy) to non-CNS lesions.
History or clinical evidence of any surgical or medical condition which the investigator judges as likely to interfere with the results of the study or pose an additional risk in participating e.g., rapidly progressive or uncontrolled disease involving a major organ system-vascular, ophthalmologic, cardiac (clinically important abnormalities in rhythm, conduction or morphology of resting ECG, uncontrolled hypertension, uncontrolled symptomatic heart failure), pulmonary, gastrointestinal, gynecologic, hematologic, neurologic, neoplastic, renal, endocrine, autoimmune or an immunodeficiency, or clinically significant active psychiatric or abuse disorders.
