This phase Ib trial evaluates the best dose and side effects of MRX-2843 when given in combination with osimertinib in treating patients with EGFR gene mutant non-small cell lung cancer that has spread to other places in the body (advanced). MRX-2843 and osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Patients must have histologically confirmed metastatic non-small cell lung cancer (NSCLC) with activating EGFR mutation including typical and atypical mutations in egfr exons 19 and 21
Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
Patients in the expansion cohort 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 (>= 2 cm) by chest x-ray or as >= 10 mm (>= 1 cm) with computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam
Ability to safely swallow oral medication
Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1)
Patients who are receiving any other investigational agents
Patients with symptomatic untreated brain metastases would be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patient with treated or asymptomatic untreated brain metastasis is allowed on study
