- Brief Summary
Though patients whose tumors harbor EGFR T790M mutation appear to benefit from rociletinib, there is a need to understand the molecular mechanisms that lead to primary and acquired resistance to rociletinib. The investigators propose to conduct a clinical trial of rociletinib of patients with EGFR-mutant NSCLC with activating EGFR mutations (including exon 19 deletion or L858R mutation), with or without EGFR T790M mutation. In these patients, pre-treatment and post-progression biopsy specimens will be subjected to genomic analysis to fully understand the clonal evolution and the molecular mechanisms underpinning treatment resistance.

-
Tumor tissue available and deemed adequate for genomic studies.
-
Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for 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 immediately.
-
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 corticosteroids.)
-
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 medication.
-
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 obliterans), drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted.
-
Class II to IV heart failure as defined by the New York Heart Association functional 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 with a cardiologist if appropriate, to be eligible.
-
Any of the following cardiac abnormalities or history:
- Clinically significant abnormal 12-lead ECG, QT interval corrected using Fridericia's method (QTcF) > 450 msec
- Inability to measure QT interval on ECG
- Personal or family history of long QT syndrome
- Implantable pacemaker or implantable cardioverter defibrillator
- Resting bradycardia < 55 beats/min
-
Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 7 days of study entry.
-
Known HIV-positivity on combination antiretroviral therapy because of the potential for pharmacokinetic interactions with rociletinib. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
-
Active hepatitis B virus (HBV) defined by positive hepatitis B surface antigen (HBsAg) test at screening. Patients with past or resolved HBV infection (defined by a negative HBsAg test and a positive anti-hepatitis B core antigen (anti-HBc) antibody test) are eligible. HBV DNA must be obtained in these patients prior to first day of study treatment.
-
Active hepatitis C virus (HCV). Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.
-
Active tuberculosis.
-
Presence of active GI disease (including GI bleeding or ulceration) or other condition that could affect GI absorption) (e.g. malabsorption syndrome, history of biliary tract disease).

Group Intervention Description Arm 1: Rociletinib Biopsy * Rociletinib is an oral drug which will be administered on an outpatient basis at a dose of 500 mg twice per day during each 28-day cycle. * After completion of cycle 1, patients who tolerate the 500 mg twice per day dose without significant adverse effect may increase dosing to 625 mg twice per day at the discretion of the investigator Arm 1: Rociletinib Blood draw * Rociletinib is an oral drug which will be administered on an outpatient basis at a dose of 500 mg twice per day during each 28-day cycle. * After completion of cycle 1, patients who tolerate the 500 mg twice per day dose without significant adverse effect may increase dosing to 625 mg twice per day at the discretion of the investigator Arm 1: Rociletinib Rociletinib * Rociletinib is an oral drug which will be administered on an outpatient basis at a dose of 500 mg twice per day during each 28-day cycle. * After completion of cycle 1, patients who tolerate the 500 mg twice per day dose without significant adverse effect may increase dosing to 625 mg twice per day at the discretion of the investigator

* Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.Overall survival (OS) Until death (estimated median of 8 months) Progression-free survival (PFS) Until the time of progression (estimated median of 3 months) -PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
