Lung Cancer Clinical Trial
Testing Trametinib and Dabrafenib as a Potential Targeted Treatment in Cancers With BRAF Genetic Changes (MATCH-Subprotocol H)
This phase II MATCH treatment trial identifies the effects of trametinib and dabrafenib in patients whose cancer has genetic changes called BRAF V600 mutations. Dabrafenib may stop the growth of cancer by blocking BRAF proteins which may be needed for cell growth. Trametinib may stop the growth of cancer cells by blocking MEK proteins which, in addition to BRAF proteins, may also be needed for cell growth. Researchers hope to learn if giving trametinib with dabrafenib will shrink this type of cancer or stop its growth.
I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma.
I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma.
II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms.
IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens.
Patients receive dabrafenib mesylate orally (PO) twice daily (BID) and trametinib dimethyl sulfoxide PO once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months if less than 2 years from study entry, and then every 6 months for year 3 from study entry.
Patients must have met applicable eligibility criteria in the Master MATCH Protocol prior to registration to treatment subprotocol
Patients must have a BRAF V600E or, V600K, V600R or V600D mutation, or another aberration, as identified via the MATCH Master Protocol
Prothrombin time (PT)/International normalized ratio (INR) and partial thromboplastin time (PTT) =< 1.3 x institutional ULN; subjects receiving anticoagulation treatment may be allowed to participate with INR established within the therapeutic range prior to registration to treatment
Patients must have an ECHO or a nuclear study (multigated aquisition scan [MUGA] or First Pass) within 4 weeks prior to registration to treatment and must not have a left ventricular ejection fraction (LVEF) < the institutional lower limit of normal (LLN). If the LLN is not defined at a site, the LVEF must be > 50% for the patient to be eligible
Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have NONE of the following cardiac criteria:
Clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block)
Treatment-refractory hypertension defined as a blood pressure of systolic > 140 mmHg and/or diastolic > 90 mmHg which cannot be controlled by anti-hypertensive therapy
Patients who previously received monoclonal antibody therapy (eg. ipilimumab and others) must have stopped the prior therapy for 8 or more weeks before starting on trametinib and dabrafenib
Patients with a diagnosis of metastatic melanoma from a cutaneous, acral, mucosal, or unknown primary site are excluded
Patients with a diagnosis of papillary thyroid cancer are excluded
Patients with a diagnosis of colorectal adenocarcinoma are excluded
Patients with a diagnosis of non-small cell lung cancer are excluded
Patients with a history of interstitial lung disease or pneumonitis are excluded
Patients must not have known hypersensitivity to dabrafenib and trametinib or compounds of similar chemical or biologic composition or to dimethyl sulfoxide (DMSO)
Patients must not have a history or current evidence/risk of retinal vein occlusion (RVO). An eye exam is required at baseline
Patients who previously received MEK inhibitors (including, but not limited to, trametinib, binimetinib, cobimetinib, selumetinib, RO4987655 (CH4987655), GDC-0623 and pimasertib) will be excluded
Patients who previously received BRAF inhibitors (including, but not limited to, dabrafenib (Tafinlar), vemurafenib (PLX-4720) (Zelboraf), RAF265, LGX818 (encorafenib), RO5212054 (PLX3603), ARQ 736, XL281 (BMS-908662), CEP-32496, and the BRAF/MEK dual inhibitor (RO5126766) will be excluded
Patients with prior exposure to dabrafenib or trametinib on another treatment subprotocol of the MATCH trial are excluded
Current use of a prohibited medication. Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A or CYP2C8 are ineligible. Current use of, or intended ongoing treatment with: herbal remedies (e.g., St. John's wort), or strong inhibitors or inducers of P-glycoprotein (Pgp) or breast cancer resistance protein 1 (Bcrp1) should also be excluded
Patients with a history of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection are excluded. An exception will be patients with cleared HBV and HCV infection which will be allowed on study
Patients with history of RAS mutation-positive tumors are not eligible regardless of interval from the current study
NOTE: Prospective RAS testing is not required. However, if the results of previous RAS testing are known, they must be used in assessing eligibility
