- Brief Summary
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.
- Detailed Description
PRIMARY OBJECTIVE:
I. To determine the efficacy (6-months progression free survival \[PFS\] rate) of defactinib and avutometinib when combined with nivolumab in patients with LKB1 mutated lung adenocarcinoma.
SECONDARY OBJECTIVE:
I. To evaluate response rate, overall survival and toxicity assessment.
TERTIARY/EXPLORATORY OBJECTIVE:
I. Biomarker evaluation will be conducted on archived tumor samples and on-study biopsies obtained in a subset of patients.
OUTLINE:
Patients receive defactinib orally (PO) twice daily (BID) on days 1-21, avutometinib PO twice weekly on Monday and Thursday, Tuesday and Friday or Wednesday and Saturday for 21 days and nivolumab intravenously (IV) on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo biopsy, blood sample collection, computed tomography (CT) or positron emission tomography (PET) on study.
After completion of study treatment, patients are followed up every 3 months for up to 5 years.

- Primary Outcome Measures
Name Time Method Progression free survival (PFS) At 6 months PFS will be defined as the time from the date of first protocol therapy to the date of first documentation of disease progression or death due to any cause, whichever occurs first. PFS will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. PFS will be calculated with a 95% confidence interval using Kaplan-Meier method based on the efficacy evaluable population.
- Secondary Outcome Measures
Name Time Method Duration of response (DOR) At response to recurrent or progressive disease up to 5 years DOR will be measured from the time measurement criteria are met for complete response or partial response (whichever is first recorded) until the first date that recurrent or progressive disease is documented. Summary statistics will be used to describe the mean and median DOR.
Incidence of adverse events (AEs) Up to 30 days after last dose of study treatment AEs will be graded using National Cancer Institute Common Toxicity Criteria for Adverse Events v5.0. All AEs will be summarized and described within each cohort. The incidence of severe events or toxicities will be described as well as the proportion of patients with grade 3 or higher toxicity.
PFS At start of treatment to progression or death up to 5 years PFS will be defined as the time from the date of first protocol therapy to the date of first documentation of disease progression or death due to any cause, whichever occurs first. PFS will be evaluated using RECIST v1.1. The Kaplan-Meier method will be used to estimate the median PFS with 95% confidence interval.
Overall survival (OS) At start of treatment to death up to 5 years OS will be measured from the date of first protocol treatment to the date of death. The Kaplan-Meier method will be used to estimate OS with 95% confidence interval.
