             20% OR ≥ 3 mm during the past 2 years.

             -- Subjects must have a target meningioma that is not amenable to surgery due to

               -  congestive heart failure New York Heart Association Grade ≥2 ( ventricular
                  arrhythmias requiring continuous therapy)

               -  supraventricular arrhythmias including atrial fibrillation, which are
                  uncontrolled

               -  haemorrhagic or thrombotic stroke, including transient ischaemic attacks or any
                  other central nervous system bleeding

               -  History of drug abuse or alcohol abuse, as judged by the Investigator

          -  Abnormal echocardiogram (ECHO) or multi-gated acquisition scan (MUGA) at baseline
             (left ventricular ejection fraction [LVEF] <55%. Appropriate correction to be used if
             a MUGA is performed.

          -  Pre-existing renal disease including glomerulonephritis, nephritic syndrome, Fanconi
             Syndrome or renal tubular acidosis

          -  Mean resting corrected QT interval (QTc), calculated using Fridericia's formula, > 470
             msec obtained from 3 electrocardiograms (ECGs), family or personal history of long or
             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 Diabetes Type I or 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,
             hypokalaemia, congenital long QT syndrome, family history of long QT syndrome or
             unexplained sudden death under 40 years-of-age).

          -  Vaccinated with live, attenuated vaccines within 4 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. Note: patients who are likely to require surgery or radiation for
             NF2-related tumors during the first year of treatment in the investigator's opinion
             should not be enrolled on this clinical trial.

          -  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.

          -  Involvement in the planning and/or conduct of the study (applies to both AstraZeneca,
             CRO staff, and/or staff at the CPU)
