A Phase 2 Study of Defactinib and Avutometinib, in Combination With Nivolumab for Patients With Anti-PD1 Refractory LKB1-Mutant Advanced Lung Adenocarcinoma
This phase II trial tests how well defactinib and avutometinib in combination with nivolumab works in treating patients with LKB1-mutant non-small cell lung cancer that has not responded (refractory) to an anti-PD1 treatment and may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Defactinib and avutometinib belong to a class of drugs called kinase inhibitors. These drugs target kinase proteins found in tumor cells. Tumor cells need these proteins to survive and grow. By blocking these proteins, defactinib and avutometinib may cause tumors to stop growing or grow more slowly. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the tumor and may interfere with the ability of tumor cells to grow and spread. Giving defactinib and avutometinib in combination with nivolumab may kill more tumor cells in patients with anti-PD1 refractory LKB1-mutant advanced non-small cell lung cancer.
• Patients must have been histologically or cytologically diagnosed with non-small cell lung cancer, specifically lung adenocarcinoma
• Patients must have advanced stage disease that is not amenable to combined modality therapy or surgical resection
• Patients must have known LKB1 mutation
• COHORT A ONLY: Patients must have known KRAS mutation
• Patients must have progressed on prior therapy with immune checkpoint inhibitor alone and first line chemotherapy, either combined or sequentially, for advanced stage disease. No other lines of chemotherapy in the advanced stage therapy is allowed. The exception is patients with KRAS G12C are also allowed the use of one line of targeted Food and Drug Administration (FDA) approved therapy
• Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT scan
• Age ≥ 18 years
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
• Adequate recovery from toxicities related to prior treatments to at least grade 1 by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0. Exceptions include alopecia and peripheral neuropathy grade ≤ 2
• Absolute neutrophil count ≥ 1,500/mcL
• Hemoglobin ≥ 8.0
• Platelets ≥ 100,000/mcL
• Total bilirubin ≤ 1.5 x upper limit of normal (ULN) for the institution; patients with Gilbert syndrome may enroll if total bilirubin \< 3.0 mg/dL (51 umole/L)
• Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT)(serum glutamic pyruvic transaminase \[SGPT\]) alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN (or \< 5 x ULN in patients with liver metastases)
• Creatinine clearance ≥ 60 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal
• Patients must have the ability to ingest oral medications
• The effects of defactinib and avutometinib on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry,for the duration of study participation, for 3 months following the last dose of study therapy for male patients, and 1 month following the last dose of study therapy for female patients. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
• Patients must be able to understand and be willing to sign a written informed consent document
• Baseline corrected QT (QTc) interval \< 460 ms for women and ≤ 450 ms for men (average of triplicate readings) (CTCAE grade 1) using Fredericia's QT correction formula. NOTE: This criterion does not apply to patients with a right or left bundle branch block
