Patient case: 11-year-old male with Peutz-Jeghers syndrome; genetic feature: STK11

Clinical trial: BKM120 in Esophageal Squamous Cell Carcinoma After Failure of First Line Chemotherapy

Summary: There is a need for more effective therapy for patients with esophageal squamous cell carcinoma who developed disease progression after first line therapy. Currently, there is no standard second-line therapy for this disease.
  BKM-120 is a pan-PI3K inhibitor currently tested in clinical trials. In a cellular model of oral-esophageal carcinogenesis, it has shown that EGFR overexpression activated PI3/AKT pathway. Therfore, there is interest to see the efficacy and safety of BKM120 in this setting.

  -  Potassium, calcium, magnesium within normal limits for the institution
  -  Serum Creatinine ≤ 1.5 x ULN or Creatinine clearance > 60 mL
  -  AST and ALT not more than 2.5 times ULN (not more than 5.0 times ULN if there is liver metastasis)

  Exclusion Criteria:

  -  Patients with controlled and asymptomatic CNS metastases may participate in this trial. As such, the patient must have completed any prior treatment for CNS metastases > 28 days (including radiotherapy and/or surgery) prior to enrollment in this study and should not be receiving chronic corticosteroid therapy for the CNS metastases.
  -  Patient has a concurrent malignancy or has a malignancy within 5 years of study enrollment, (with the exception of nonmelanoma skin cancer or cervical carcinoma in situ.
  -  Patient has any of the following mood disorders as judged by the Investigator or a Psychiatrist, or meets the cut-off score of ≥ 10 in the PHQ-9 or a cut-off of ≥ 15 in the GAD-7 mood scale, respectively, or selects a positive response of '1, 2, or 3' to question number 9 regarding potential for suicidal thoughts ideation in the PHQ-9 (independent of the total score of the PHQ-9)
  -  Medically documented history of or active major depressive episode, bipolar disorder (I or II), obsessive-compulsive disorder, schizophrenia, a history of suicidal attempt or ideation, or homicidal ideation (immediate risk of doing harm to others) ≥ CTCAE grade 3 anxiety
  -  Patient is concurrently using other approved or investigational antineoplastic agent
  -  Patient has had major surgery within 28 days prior to starting study drug or has not recovered from major side effects of the surgery
  -  Patient has poorly controlled diabetes mellitus(HbA1c > 8 %)
  -  Patient has active cardiac disease including any of the following:
  -  LVEF < 50%
  -  QTc > 480 msec on screening ECG (using the QTcF formula)
  -  Angina pectoris that requires the use of anti-anginal medication
  -  Ventricular arrhythmias except for benign premature ventricular contractions
  -  Supraventricular and nodal arrythmias requiring a pacemaker or not controlled with medication
  -  Conduction abnormality requiring a pacemaker
  -  Valvular disease with documented compromise in cardiac function
  -  Symptomatic pericarditis
  -  Patient has a history of cardiac dysfunction including any of the following;
  -  Myocardial infarction within the last 6 months, documented by persistent elevated cardiac enzymes or persistent regional wall abnormalities on assessment of LVEF function
  -  History of documented congestive heart failure (New York Heart Association functional classification III-IV)
  -  Documented cardiomyopathy
  -  Patient is currently receiving treatment with QT prolonging medication known to have a risk to induce Torsades de Pointes, and the treatment cannot be discontinued or switched to a different medication prior to starting study drug
  -  Inability to swallow, impaired gastrointestinal (GI) function, or GI disease that would significantly alter the absorption of study drugs or preclude the use of oral medications
  -  Patient has other concurrent severe and/or uncontrolled medical condition that would, in the investigator's judgment contraindicate her participation in the clinical study (e.g.,chronic pancreatitis, active chronic hepatitis etc.)
  -  Patient is currently being treated with drugs known to be moderate and strong inhibitors or inducers of isoenzyme CYP3A, and the treatment cannot be discontinued or switched to a different medication prior to starting study drug.
