Eligibility |
Inclusion Criteria:
- Males and females >=18 years of age
- Histologically or cytologically confirmed non-small cell lung cancer (NSCLC),
performed on a biopsy that occurred within the last 90 days. This biopsy can be
deferred if the procedure is deemed to represent an unacceptable safety risk to the
patient by the Principal Investigator and as long as the patient has a prior biopsy
showing non-small cell lung cancer.

samples by Clinical Laboratory Clinical Laboratory Improvement Amendments
(CLIA)-approved test

(including erlotinib, afatinib, gefitinib, & rocelitinib) are eligible if they
received no more than 28 days of treatment, and if there is no evidence of grade 2 or
greater treatment adverse events possibly related to treatment with the EGFR TKI.
- Positron emission tomography (PET)-computed tomography (CT) within the last 60 days
showing radiographic stage I to IIIa lung cancer (mediastinal staging biopsy is
allowed but not required)

limit of normal (ULN)
- Bilirubin =< 1.5 x ULN, (Patients with documented Gilbert's syndrome and conjugated
bilirubin within the normal range may be allowed into the study; in this event, it
will be documented that the patient was eligible based on conjugated bilirubin levels)
- Potassium and magnesium within normal range, patients may receive supplements to meet
this requirement
- Leukocytes > 3,000/microliter (mcL)
- Hemoglobin >= 9 g/dL, with no blood transfusions in the 28 days prior to study entry

within 3 days prior to the first dose of study treatment and agree to use highly
effective contraception, during the study and for 90 days following the last dose of
osimertinib
- Women of childbearing potential (WoCBP): women between menarche and menopause who
have not been permanently or surgically sterilized and are capable of procreation
- Women NOT of childbearing potential: women who are permanently or surgically
sterilized or postmenopausal
- Permanent sterilization includes hysterectomy and/or bilateral oophorectomy
and/or bilateral salpingectomy but excludes bilateral tubal occlusion; tubal
occlusion is considered a highly effective method of birth control but does
not absolutely exclude possibility of pregnancy; (the term occlusion refers
to both occluding and ligating techniques that do not physically remove the
oviducts)
- Women who have undergone tubal occlusion should be managed on trials as if they
are of WoCBP (e.g. undergo pregnancy testing etc., as required by the study
protocol)
- Women will be considered postmenopausal if they are amenorrhoeic for 12 months
without an alternative medical cause; the following age-specific requirements
apply:
- Women under 50 years old will be considered postmenopausal if they have been
amenorrhoeic for 12 months or more following cessation of exogenous hormonal
treatments and with luteinizing hormone and follicle-stimulating hormone
levels in the postmenopausal range
- Women over 50 years of age will be considered postmenopausal if they have
been amenorrhoeic for 12 months or more following cessation of all exogenous
hormonal treatments
- Acceptable contraception methods are:
- Total sexual abstinence (abstinence must be for the total duration of the
trial and the follow-up period)
- Vasectomized sexual partner plus male condom (with participant assurance
that partner received post-vasectomy confirmation of azoospermia)
- Tubal occlusion plus male condom
- Intra-uterine device - provided coils are copper-banded, plus male condom
- Intra-uterine system (IUS) levonorgestrel IUS (e.g., Mirena), plus male
condom

- Norelgestromin / ethinylestradiol transdermal system plus male condom
- Intravaginal device (e.g., ethinylestradiol and etonogestrel) plus male
condom
- Cerazette (desogestrel) plus male condom (Cerazette is currently the only
highly efficacious progesterone based pill)
- Unacceptable Contraception Methods The following methods are considered not to be
highly effective and are therefore not acceptable contraceptive methods:
- Triphasic combined oral contraceptives
- All progesterone only pills except, Cerazette
- All barrier methods, if intended to be used alone
- Non-copper containing intra-uterine devices
- Fertility awareness methods
- Coitus interruptus
- Men with a female partner of childbearing potential must have either had a prior
vasectomy agree to use effective contraception as described in the full protocol for
at least 14 days prior to administration of the first dose of study treatment, during
the study, and for 90 days following the last dose of osimertinib
Exclusion Criteria:
- Leptomeningeal carcinomatosis or other central nervous system (CNS) metastases

for prior malignancy was completed > 12 months prior and/or bone marrow transplant > 2
years prior
- Patients who are currently receiving treatment with contraindicated corrected QT
interval (QTc) prolonging medications or potent CYP3A4 inducers, if that treatment
cannot be either discontinued or switched to a different medication prior to first day
of study treatment. All patients must try to avoid concomitant use of any medications,
herbal supplements and/or ingestion of foods with known inducer effects
- Any of the following cardiac abnormalities or history:
- Mean resting corrected QT interval (QTc) > 470 msec, obtained from 3
electrocardiograms (ECGs), using the screening clinic ECG machine derived QTc
value
- Any clinically important abnormalities in rhythm, conduction or morphology of
resting ECG e.g. complete left bundle branch block, third degree heart block and
second degree heart block
- Any factors that increase the risk of QTc prolongation or risk of arrhythmic

medical regimen that is optimized in the opinion of the treating physician, in
consultation with a cardiologist if appropriate, to be eligible
- Patients who have experienced untreated and/or uncontrolled cardiovascular conditions
and/or have symptomatic cardiac dysfunction (unstable angina, congestive heart
