For this reason and
because mTOR kinase inhibiting agents are known to be teratogenic, female patients
must be willing to use 2 forms of highly effective contraception (per institution
standards) from the time of screening until four weeks after discontinuing study, must
not be breast feeding, and must have a negative pregnancy test prior to start of
dosing if of child bearing potential or must have evidence of non-childbearing
potential by fulfilling one of the following criteria at screening:
- (1)
post-menopausal women, defined as either women aged more than 50 years and amenorrheic
for at least 12 months following cessation of all exogenous hormonal treatments, or
(2) women under 50 years old who have been amenorrheic for at least 12 months
following the cessation of exogenous hormonal treatments, and have serum
follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels in the
postmenopausal range for the institution.
Alternatively, women must have documentation
of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or
bilateral salpingectomy but not tubal ligation.
Male patients should either be surgically sterile or willing to use an effective barrier
method of contraception during the study and for 16 weeks following the last dose of study
treatment if sexually active with a female of childbearing potential. If not done
previously, storage of sperm prior to receiving AZD2014 will be advised to male patients
with a desire to have children.

if taken within the stated washout periods before the first dose of study treatment
(see Appendix B)
- Exposure to specific substrates of the drug transporters OATP1B1, OATP1B3, MATE1 and
MATE2K within the appropriate wash-out period (a minimum of 5 x reported elimination
half-life) before the first dose of study treatment (see Appendix B)
- Any hematopoietic growth factors (e.g., filgrastim [granulocyte colony-stimulating
factor; G-CSF], sargramostim [granulocyte-macrophage colony-stimulating factor;
GM-CSF]) within 14 days prior to receiving study treatment.
- - Pre-treatment with other mTOR inhibitors may be allowed and should be discussed with
the medical monitor.
- - Current refractory nausea and vomiting, malabsorption syndrome, disease significantly
affecting gastrointestinal function, resection of the stomach or small bowel,
symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete
bowel obstruction.
- - Previous meningioma progression during treatment with other mTORC1/2 inhibitors (but
not mTORC1 inhibitors such as everolimus or other rapalogs).

uncompensated respiratory or cardiac conditions, uncontrolled hypertension, active
bleeding diatheses, active hepatitis B or C infection, known active human
immunodeficiency virus (HIV) infection, or psychiatric illness/social situations that
would limit compliance with study requirements.
Screening for chronic conditions is
not required.
- - History of other malignancies, except: Malignancy treated with curative intent and
with no known active disease present for ≥5 years before the first dose of study drug
and felt to be at low risk for recurrence by treating physician, (2) adequately
treated non-melanoma skin cancer or lentigo maligna without evidence of disease, (3)
adequately treated carcinoma in situ without evidence of disease, or (4) Gleason 6
prostate cancer under observation.
- - Patients who have experienced any of the following procedures or conditions currently

other central nervous system bleeding.
- - History of drug abuse or alcohol abuse, as judged by the Investigator.

short QT syndrome, Brugada syndrome or known history of QTc prolongation or Torsade de
Pointes within 12 months of the patient entering in the study.
- - Patients with uncontrolled Type II (HbA1c >8% assessed locally) as judged by the
investigator or abnormal fasting glucose value defined as >126 mg/dL (>7 mmol/L).
- - Concomitant medications known to prolong QT interval, or with factors that increase
the risk of QTc prolongation or risk of arrhythmic events (such as heart failure,
hypokalemia, congenital long QT syndrome, family history of long QT syndrome or
unexplained sudden death under 40 years-of-age).
See appendix B for a list of
medications.
- - Vaccinated with live, attenuated vaccines within four weeks of the first dose of study
drug.
- - Judgment by the Investigator that the patient is unsuitable to participate in the
study and the patient is unlikely to comply with study procedures, restrictions and
requirements.
- - Pregnant women are excluded from this study because AZD2014 is an mTORC1/2 inhibiting
agent with the potential for teratogenic or abortifacient effects.
Because there is an
unknown but potential risk for adverse events in nursing infants secondary to
treatment of the mother with AZD2014, breastfeeding should be discontinued if the
mother is treated with AZD2014.
- - HIV-positive participants on combination antiretroviral therapy are ineligible because
of the potential for pharmacokinetic interactions with AZD2014.
In addition, these
participants are at increased risk of lethal infections when treated with
marrow-suppressive therapy. Appropriate studies will be undertaken in participants
receiving combination antiretroviral therapy when indicated.
- - Involvement in the planning and/or conduct of the study (applies to both AstraZeneca,
CRO staff, and/or staff at the CPU).
