the duration of study participation. Should a woman become pregnant or suspect she is
pregnant while participating in this study, she must inform her treating physician
- Ability to understand and willingness to sign an IRB approved written informed consent
document (or that of legally authorized representative, if applicable).
- A history of other malignancy ≤ 5 years previous with the exception of basal cell or
squamous cell carcinoma of the skin which were treated with local resection only or
carcinoma in situ of the cervix.
- Currently receiving any other investigational agents.
- Received therapeutic oral or IV antibiotics within 2 weeks prior to first day of study
treatment. Patients receiving prophylactic antibiotics (e.g., to prevent a urinary
tract infection or chronic obstructive pulmonary disease exacerbation) are eligible.
- Symptomatic, untreated or unstable central nervous system or leptomeningeal
metastases. (Patients with treated and stable brain metastases (confirmed by 2 scans
at least 4 weeks apart), with no evidence of cavitation or hemorrhage in the brain
lesion are eligible provided that they are asymptomatic and do not require
- A history of allergic reactions attributed to compounds of similar chemical or
biologic composition to rociletinib or other agents used in the study.
- Currently receiving treatment with any medication that has the potential to prolong
the QT interval and the treatment cannot be discontinued or switched to a different
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, myocardial
infarction within the previous 3 months, coronary angioplasty or stenting or bypass
grafting within the past 6 months, cardiac ventricular arrhythmias requiring
medication, any history of 2nd or 3rd degree atrioventricular conduction defects,
cardiac arrhythmia, or psychiatric illness/social situations that would limit
compliance with study requirements.
- History of interstitial lung disease.
- History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis

pneumonitis on screening chest CT scan. History of radiation pneumonitis in the
radiation field (fibrosis) is permitted.

classification system. Patients with known coronary artery disease, congestive heart
failure not meeting the above criteria, or LVEF < 50% must be on a stable medial
regimen that is optimized in the opinion of the treating physician, in consultation

antiretroviral therapy when indicated.
