Trametinib in Patients With Advanced Neurofibromatosis Type 1 (NF1)-Mutant Non-small Cell Lung Cancer
Phase II trial to evaluate trametinib in patients with locally advanced non-squamous, non-small cell lung cancer (NSCLC) whose tumors harbor a non-synonymous NF-1 mutation, with progressive disease on at least one prior line of therapy.
Phase II Trial to Evaluate Trametinib in Patients With Advanced NF1-mutant Non-small Cell Lung Cancer
This is a phase II, single-arm, open-label, multicenter clinical trial evaluating the efficacy and safety of trametinib monotherapy in patients with advanced non-squamous NSCLC whose tumors non-synonymous NF1 mutations and are KRAS wildtype. Eligible patients must have documented disease progression either during or after treatment with most recent therapy and may not have received prior treatment with a MEK inhibitor. Patients with activating alterations in EGFR, ALK, and ROS-1 must also have received appropriate TKI treatment. Patients who meet eligibility criteria will receive trametinib monotherapy and followed for the primary endpoint of objective response rate and additional secondary endpoints. A total of 27 patients will be enrolled into the study, with the goals of obtaining 24 evaluable patients. Patients may continue treatment until disease progression or up to 24 months from the time of study entry or until the study is closed. All patients will be followed for 12 months.

Open to people ages 18 years and up
- Histologically or cytologically confirmed metastatic or unresectable locally advanced,non-squamous, NSCLC.
- Documented non-synonymous somatic mutation in NF1 in any tumor specimen or cell-free DNA assay by Clinical Laboratory Improvement Amendments (CLIA)-approved laboratory.
- Received at least one prior line of cancer therapy for the treatment of NSCLC; this should include at least one of the following: platinum (carboplatin or cisplatin)doublet chemotherapy (acceptable combinations include: paclitaxel, docetaxel,abraxane, pemetrexed, gemcitabine, vinorelbine, or etoposide), anti-PD1/PDL1 therapy(pembrolizumab, nivolumab, or atezolizumab), or appropriate targeted therapy in patients with activating EGFR (osimertinib, erlotinib, gefitinib, or afatinib), ALK(alectinib, crizotinib, ceritinib, brigatinib, or loralatinib), or ROS-1 (crizotininb or entrectinib) alterations; therapy may be given as monotherapy or in combination with other cancer therapy (e.g. bevacizumab, ipilumimab)
- Patients with a known activating mutation in epidermal growth factor receptor (EGFR)(Exon 19 deletion, G719A, S768I, V769L, T790M, L833F, L858R, L861Q), must have progressed or been intolerant to treatment with a first-line EGFR tyrosine kinase inhibitor (TKI) (erlotinib, afatinib, or gefitinib). Patients whose tumors were found to have an EGFR T790M mutation must also have progressed or been intolerable to treatment with osimertinib.
- Patients with a known Anaplastic lymphoma kinase (ALK)-rearrangement must have progressed or been intolerant to treatment with at least one ALK TKI: crizotinib ceritinib, alectinib,brigatinib, or loralatinib
- Patients with a known ROS-1-rearrangement must have progressed or been intolerant to treatment with crizotinib or entrectinib
- Patients with PDL1 level of >= 50%, who do not have an ALK-rearrangement or EGFR-mutation, must have progressed or been intolerant to treatment with anti-PD1/PDL1 therapy (pembrolizumab, nivolumab, or atezolizumab)
- Documented disease progression or intolerance to treatment either during or after treatment with most recent therapy.
- Willingness to undergo research biopsy.
- . Measurable disease defined by RECIST 1.1 criteria.
- . Life expectancy of at least 3 months.
- . Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
- . Age ≥ 18 years.

- . Adequate baseline organ function defined as follows:
Absolute neutrophil count: ≥ 1.2 x 109/L
- Hemoglobin: ≥ 9 g/dL
Platelets: ≥ 100 x 109/L
- PT/INR and PTT: ≤ 1.5 x upper limit of normal (ULN)

- . Women of childbearing potential must have a negative serum or urine pregnancy test within 3 days prior to study enrollment. The effects of trametinib on the developing human fetus are unknown. For this reason and because animal studies with trametinib have shown reproductive toxicity, women of child-bearing potential and men must agree to use effective methods of contraception (hormonal or barrier method of birth control) prior to study entry, for the duration of study participation, and for 4 months following discontinuation of trametinib. 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. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of study drug administration.
