NCT02971501 : Osimertinib With or Without Bevacizumab in Treating Patients With EGFR Positive Non-small Cell Lung Cancer and Brain Metastases
PhasePhase 2
AgesMin: 18 Years Max: N/A
Inclusion Criteria:

- Non-small cell lung cancer (NSCLC) with an activating EGFR mutation (exon 19 deletion,
L858R point mutation, or any other mutation known to be associated with EGFR TKI
sensitivity); presence of an activating EGFR mutation may be documented in tumor
tissue or by plasma testing if performed in a Clinical Laboratory Improvement Act
(CLIA)-certified laboratory; AND

- The presence of an EGFR T790M mutation after progression on a first- or
second-generation EGFR TKI; presence of an EGFR T790M mutation may be documented from
biopsy material from any site of disease (intra- or extra-cranial) or from plasma
testing if performed in a CLIA-certified laboratory; for patients who have disease
progression in the CNS only (with otherwise stable disease systemically), T790M
positivity is not required

- Disease progression on a first- or second-generation EGFR TKI (i.e. erlotinib,
gefitinib, or afatinib); patient may have also received prior chemotherapy or
immunotherapy but this is not required

- Patients must have at least one measurable CNS lesion that is asymptomatic, untreated,
and does not require local therapy at the time of enrollment; measurable CNS disease
is defined as a brain metastasis that can be accurately measured in at least one
dimension (longest diameter to be recorded) as >= 5 mm (>= 0.5 cm) with brain magnetic
resonance imaging (MRI); if the lesion is 5-10 mm in size and is the only measurable
disease, MRI imaging must be performed with 1.5 mm slice thickness or less; a history
of previously treated brain metastases is allowed, however any lesion present at the
time of whole brain radiotherapy or included in the stereotactic radiotherapy field
(or within 2 mm of the treated lesion) will NOT be considered "untreated" unless it is
new or documented to have progressed unequivocally since treatment

- Patients are not required to have measurable systemic (i.e. non-CNS) disease; if
present, measurable systemic disease must be able to be accurately measured in at
least one dimension (longest diameter to be recorded for non-nodal lesions and short
axis for nodal lesions) as >= 20 mm (>= 2 cm) with conventional techniques or as >= 10
mm (>= 1 cm) with spiral computed tomography (CT) scan, MRI, or calipers by clinical

- Eastern Cooperative Oncology Group (ECOG) performance status =< 2

with no seizure activity for at least 2 weeks prior to initiating trial therapy

- Female subjects should be using highly effective contraceptive measures, and must have
a negative pregnancy test and not be breast-feeding prior to start of dosing if of
child- bearing potential or must have evidence of non-child-bearing potential by
fulfilling one of the following criteria at screening:

- Post-menopausal defined as aged more than 50 years and amenorrheic for at least
12 months following cessation of all exogenous hormonal treatments

- Women under 50 years old would be consider postmenopausal if they have been
amenorrheic for 12 months or more following cessation of exogenous hormonal
treatments and with luteinizing hormone (LH) and follicle stimulating hormone
(FSH) levels in the post-menopausal range for the institution

- Documentation of irreversible surgical sterilization by hysterectomy, bilateral
oophorectomy or bilateral salpingectomy but not tubal ligation

- Fertile men should be willing to use barrier contraception during and for 4 months
after AZD9291 (osimertinib), and fertile women must agree to use adequate
contraceptive measures during and for 6 weeks after AZD9291 (osimertinib); fertile men
and women must agree to use adequate contraceptive measures during study therapy and
for at least 6 months after the completion of bevacizumab therapy; should a woman
become pregnant or suspect she is pregnant while she or her partner is participating
in this study, the patient should inform the treating physician immediately

- Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

- Symptomatic brain metastases

- Patients with brain metastases for whom complete surgical resection is clinically

- Prior treatment with a third-generation EGFR TKI (i.e. rociletinib)

- Prior treatment with agents targeting the VEGF pathway, including bevacizumab

- The use of corticosteroids to control cerebral edema or treat neurologic symptoms will
not be allowed, and patients who previously required corticosteroids for symptom
control must be off steroids for at least 3 days without recurrence of symptoms prior
to starting trial therapy; corticosteroids for other indications is allowed

- Presence of leptomeningeal disease

- Patients may not be receiving any other investigational agents and may not have
participated in a study of an investigational agent or using an investigational device
within five half-lives of the compound or 3 months, whichever is greater

- Treatment with an EGFR TKI (i.e. erlotinib, gefitinib or afatinib) within 8 days or
approximately 5 x half-life, whichever is longer, of the first dose of study treatment

- Any unresolved toxicities from prior therapy greater than Common Terminology Criteria
for Adverse Events (CTCAE) grade 1 at the time of starting study treatment with the
exception of alopecia and grade 2 platinum-therapy related neuropathy

- Concurrent, active malignancies in addition to that being studied (other than
cutaneous squamous cell carcinoma or basal cell carcinoma)

- Any contraindication to MRI (i.e. patients with pacemakers or other metal implanted
medical devices)
