Women of child-bearing potential must be willing to practice acceptable methods of birth control. Additionally, women of childbearing potential must have a negative serum pregnancy test within 14 days prior to the first dose of study medication.
You may not be if
History of another malignancy with exceptions below, or any malignancy with confirmed activating RAS mutation. Exception: (a) Subjects who have been successfully treated and are disease-free for 5 years, (b) a history of completely resected non-melanoma skin cancer, (c) successfully treated in situ carcinoma, (d) chronic lymphocytic leukemia in stable remission, or (e) indolent prostate cancer (definition: clinical stage T1 or T2a, Gleason score \<=6, and prostate-specific antigen \<10 nanogram per milliliter) requiring no or only anti-hormonal therapy, are eligible. Note: Prospective RAS testing is not required. However, if the results of previous RAS testing are known, they must be used in assessing eligibility.
Cancer therapy (chemotherapy with delayed toxicity, extensive radiation therapy, immunotherapy, biologic therapy, or major surgery) or investigational anti-cancer drugs within the last 3 weeks, or chemotherapy without delayed toxicity within the last 2 weeks, preceding the first dose of study medication.
Unresolved clinically significant toxicity greater than Grade 2 from previous anti-cancer therapy
Any serious and/or unstable pre-existing medical, psychiatric disorder or other conditions that could interfere with subject's safety, obtaining informed consent or compliance to the study procedures.
Current use of therapeutic warfarin. NOTE: Low molecular weight heparin and prophylactic low-dose warfarin are permitted
Any prohibited medication(s) or herbal preparation as described in the protocol or requires any of these medications during the study.
Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to dabrafenib, rosuvastatin, and midazolam, or excipients that contraindicate their participation; or have an allergy to cherries.
Pregnant or nursing females.
A history or evidence of cardiovascular risk including any of the following:
A QT interval corrected for heart rate using the Bazett's formula (QTcB) \>=480 millisecond (msec);
A history or evidence of current clinically significant uncontrolled arrhythmias;
A history of acute coronary syndromes (including myocardial infarction or unstable angina), coronary angioplasty, or stenting within 6 months prior to randomization
A history or evidence of current \>=Class II congestive heart failure as defined by the New York Heart Association (NYHA) guidelines
Abnormal cardiac valve morphology (\>=grade 2) documented by echocardiogram (subjects with grade 1 abnormalities \[i.e., mild regurgitation/stenosis\] can be entered on study). Subjects with moderate valvular thickening should not be entered on study.
Patients with intra-cardiac defibrillators
Presence of active GI disease or other condition (e.g., small bowel or large bowel resection) that will interfere significantly with the absorption of drugs. If clarification is needed as to whether a condition will significantly affect absorption of drugs, contact the GSK Medical Monitor.
Subjects with COPD or subjects with increased risk of respiratory depression
Subjects with narrow angle glaucoma
A history of known Human Immunodeficiency Virus (HIV), Hepatitis B Virus, or Hepatitis C Virus infection.
Subjects with brain metastases are excluded if their brain metastases are: Symptomatic; Treated (surgery, radiation therapy) but not clinically and radiographically stable one month after local therapy, OR; Asymptomatic and untreated but \> 1 cm in the longest dimension. Subjects with small (\<= 1 cm in the longest dimension), asymptomatic brain metastases that do not need immediate local therapy can be enrolled. Subjects on a stable dose of corticosteroids for more than one month, or those who have been off corticosteroids for at least 2 weeks can be enrolled. Subjects must also be off of enzyme-inducing anticonvulsants for more than 4 weeks.
