This phase Ib/II trial studies the side effects and best dose of trametinib and navitoclax and how well they work in treating patients with solid tumors that have spread to other places in the body (advanced or metastatic). Trametinib and navitoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

  • Intrauterine device (IUD)
  • Double-barrier method: male condom plus diaphragm or vaginal cap with spermicide (contraceptive sponge, jellies or creams)
  • Men with a female partner of childbearing potential must have either had a prior vasectomy or agree to use effective contraception; additionally, male subjects (including those who are vasectomized) whose partners are pregnant or might be pregnant must agree to use condoms for the duration of the study and for 4 months following completion of therapy
  • Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to initiation of treatment; women will be considered not of childbearing potential if they are surgically sterile (bilateral oophorectomy or hysterectomy) and/or post-menopausal (amenorrheic for at least 12 months); 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; the potential hazard to the fetus should be explained to the patient and partner (as applicable)
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

  • History of another malignancy; exception: patients who have been disease-free for 3 years, or patients with a history of completely resected non-melanoma skin cancer or any carcinoma in situ and/or patients with indolent second malignancies, are eligible; consult the Cancer Therapy Evaluation Program (CTEP) medical monitor if unsure whether second malignancies meet the requirements specified above
  • History of interstitial lung disease or pneumonitis
  • Any major surgery, extensive radiotherapy (> 15 days of treatment), chemotherapy with delayed toxicity, biologic therapy, or immunotherapy within 21 days prior to first dose of study treatment and/or daily or weekly chemotherapy without the potential for delayed toxicity within 14 days prior to first dose of study treatment
  • Use of other investigational drugs within 28 days (or five half-lives, whichever is shorter; with a minimum of 14 days from the last dose) preceding the first dose of study drug(s) and during the study
  • Patients with known brain metastases should 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; exception: patients with brain metastases will be allowed on study if they have clinically controlled neurologic symptoms, defined as surgical excision and/or radiation therapy followed by 21 days of stable neurologic function and no evidence of central nervous system (CNS) disease progression as determined by computed tomography (CT) or magnetic resonance imaging (MRI) within 21 days prior to the first dose of study drug
  • Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to trametinib, or excipients or to dimethyl sulfoxide (DMSO), or to compounds of similar chemical or biologic composition to navitoclax
  • Current use of a prohibited medication; the following medications or non-drug therapies are prohibited:
  • Other anti-cancer therapy while on study treatment; (note: megestrol [Megace] if used as an appetite stimulant is allowed)
  • Concurrent treatment with bisphosphonates is permitted; however, treatment must be initiated prior to the first dose of study therapy; prophylactic use of bisphosphonates in patients without bone disease is not permitted, except for the treatment of osteoporosis
  • Because the composition, pharmacokinetics (PK), and metabolism of many herbal supplements are unknown, the concurrent use of all herbal supplements is prohibited during the study (including, but not limited to, St. John's wort, kava, ephedra [ma huang], ginkgo biloba, dehydroepiandrosterone [DHEA], yohimbe, saw palmetto, or ginseng)
  • Due to the expected dose-limiting toxicity of thrombocytopenia, the following concomitant medications are not allowed during navitoclax administration: Warfarin, clopidogrel (plavix), ibuprofen, tirofiban (aggrastat), and other anticoagulants, drugs, or herbal supplements that affect platelet function are excluded, with the exception of low-dose anticoagulation medications (such as heparin) that are used to maintain the patency of a central intravenous catheter; aspirin will not be allowed within 7 days prior to the first dose of navitoclax or during navitoclax administration; however, subjects who have previously received aspirin therapy for thrombosis prevention may resume a low dose (i.e., maximum 100 mg QD) of aspirin if platelet counts are stable (>= 50,000/mm^3) through 6 weeks of navitoclax administration; all decisions regarding treatment with aspirin therapy will be determined by the investigator in conjunction with the medical monitor
  • Preclinical studies indicate that navitoclax is metabolized by CYP3A4, is a moderate inhibitor of CYP2C8, and is a strong inhibitor of CYP2C9; therefore, caution should be exercised when dosing navitoclax concurrently with CYP2C8 and CYP2C9 substrates; common CYP2C8 substrates include paclitaxel, statins, and glitazones, whereas CYP2C9 substrates include phenytoin and warfarin; when possible, investigators should switch to alternative medications or monitor the patients closely (particularly in the case of medications that have a narrow therapeutic window such as warfarin; use of warfarin is specifically prohibited while on study); CYP3A inhibitors such as ketoconazole and clarithromycin are not allowed 7 days prior to the first dose of navitoclax or during navitoclax administration
  • Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated list; medical reference texts such as the Physicians' Desk Reference may also provide this information; as part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
  • Patient instructions and information of possible drug interactions will be given to all patients upon enrollment in this study
  • History or current evidence/risk of retinal vein occlusion (RVO)
  • History or evidence of cardiovascular risk including any of the following:
  • Left ventricle ejection fraction (LVEF) < LLN
  • A QT interval corrected for heart rate using the Bazett's formula QTcB >= 480 msec
  • History or evidence of current clinically significant uncontrolled arrhythmias (exception: patients with controlled atrial fibrillation for > 30 days prior to enrollment are eligible)
  • History of acute coronary syndromes (including myocardial infarction and unstable angina), coronary angioplasty, or stenting within 6 months prior to randomization
  • History or evidence of current >= class II congestive heart failure as defined by the New York Heart Association (NYHA) functional classification system

  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Subject has an underlying condition predisposing them to bleeding or currently exhibits signs of clinically significant bleeding
  • Subject has a recent history of non-chemotherapy-induced thrombocytopenic-associated bleeding within 1 year prior to the first dose of study drug
  • Subject has a significant history of cardiovascular disease (e.g., myocardial infarction [MI], thrombotic or thromboembolic event in the last 6 months)
  • Pregnant women or nursing mothers; animal reproductive studies have not been conducted with trametinib or navitoclax; therefore, the study drug must not be administered to pregnant women or nursing mothers
