Further study details as provided by Canadian Cancer Trials Group:

Primary Outcome Measures:
  • Overall response rate [ Time Frame: 30 months ]
    To determine the overall response rate (complete + partial response) to oral buparlisib in patients with relapsed and refractory chronic lymphocytic leukemia.


Secondary Outcome Measures:
  • Number of adverse events in patients [ Time Frame: 30 months ]
    To evaluate the safety and tolerability of buparlisib administered at 100 mg per day on a 28 day cycle, in patients with previously treated chronic lymphocytic leukemia.

  • Efficacy of buparlisib (duration of response rate and progression free survival); composite outcome measure. [ Time Frame: 30 months ]
    • To evaluate additional measures of efficacy including duration of response rate and progression free survival
    • To explore potential molecular factors which may be prognostic or predictive of response or of relapse.
    • To prospectively validate a survival prediction scale.


Enrollment: 14
Actual Study Start Date: January 30, 2015
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Buparlisib
100mg daily orally every 28 days
Drug: Buparlisib

Detailed Description:

Buparlisib has been shown to shrink tumours in animals. It has been studied in some people and seems promising but it is not clear if it can offer better results than standard treatment.

The standard or usual treatment for this disease is chemotherapy, targeted therapy or radiation, either alone or in combination.

Criteria

Inclusion Criteria:

  • Patients must have recovered (to ≤ grade 2) from all reversible toxicity related to prior systemic therapy, and have adequate washout from prior chemotherapy and investigational agents defined as the longest of:

    • two weeks
    • standard cycle length of prior regimen (e.g. 28 days for FCR)
    • 5 half-lives for investigational drugs

Not permitted:

• prior treatment with buparlisib (BKM120)

  • Patients may have had radiation, provided a minimum of 21 days has elapsed prior to enrollment. Patients must have recovered from any acute toxic effects from radiation prior to registration
  • Previous surgery is permitted provided that wound healing has occurred and at least 14 days have elapsed if surgery was major
  • Absolute neutrophil counts (ANC): ≥ 1.0 x 10^9/L
  • Platelets ≥ 50/min x 10^9/L and more than 5 days since last transfusion
  • Creatinine clearance* ≥ 50 mL/min
  • Bilirubin** ≤ 1.5 x upper normal limit (UNL)
  • Alanine aminotransferase (AST) and aspartate aminotransferase (ALT) ≤ 1.5 x UNL or ≤ 3 x UNL if hepatic involvement with CLL
  • Potassium and calcium Within normal limits for laboratory (supplementation permitted)
  • Glucose (fasting) < 7.8 mmol/L (AND HbA1c ≤ 8% if diabetic)

    * Creatinine clearance as calculated by Cockcroft-Gault formula or by 24 hour urine measurement: Females: GFR = 1.04 x (140-age) x weight in kg serum creatinine in μmol/L Males: GFR = 1.23 x (140-age) x weight in kg serum creatinine in μmol/L

    ** Direct if patient known to have Gilbert's syndrome

  • Patient consent must be obtained according to local Institutional and/or University Human Experimentation Committee requirements
  • Patients must be accessible for treatment and follow up. Patients registered on this trial must be treated and followed at the participating centre
