encorafenib or their excipients

genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are
unknown:

contraception

contraception that are highly effective or acceptable, and to not donate ova from
screening until 30 days after the last dose of study drug
- NOTE: Male participants must agree to use methods of contraception that are
highly effective or acceptable, and to not donate sperm from screening until 90
days after the last dose of study drug

of the investigator, would make the patient inappropriate for entry into this study or
interfere significantly with the proper assessment of safety and toxicity of the
prescribed regimens
- Immunocompromised patients and patients known to be HIV positive and currently
receiving antiretroviral therapy. NOTE: Patients known to be human immunodeficiency
virus ( HIV) positive, but without clinical evidence of an immunocompromised state,
are eligible for this trial
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, cardiac arrhythmia, or psychiatric
illness/social situations that would limit compliance with study requirements

the primary neoplasm
- Patients who have had another active malignancy within the past two years are
ineligible EXCEPT FOR patients with cervical cancer in situ, in situ carcinoma of the
bladder, non-melanoma carcinoma of the skin, or patients who have had therapy with

- Uncontrolled or symptomatic brain metastases or leptomeningeal carcinomatosis that are
not stable, require steroids, are potentially life-threatening or have required
radiation =< 28 days prior to registration.
