Primary Outcome Measures:
  • Dose Limiting Toxicities [ Time Frame: 6 weeks (42 days) ] [ Designated as safety issue: Yes ]
    Dose Limiting Toxicities (DLTs) during the first 6 weeks (42 days) of the combination treatment of LDE225 and BKM120.


Secondary Outcome Measures:
  • Number of Patients with Adverse Events and Serious Adverse Events [ Time Frame: Following signing of the informed consent form, up to and including 30 days following the last dose ] [ Designated as safety issue: Yes ]
    Adverse and serious adverse events, changes in hematology and chemistry values, and assessment of physical and/or neurological examinations, vital signs, and electrocardiograms

  • Objective response rate (ORR) [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    ORR is the proportion of patients with best overall response of complete or partial response. ORR will be used to evaluate preliminary efficacy of the combination therapy. Tumors will be assessed using Investigator read CT/MRI assessments evaluated as per RECIST 1.1, except for patients with glioblastoma multiforme (GBM) who will be assessed per the RANO Criteria.

  • Early progression rate (EPR) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    EPR is the proportion of patients with progressive disease within 6 months of the start of treatment. EPR will be used to evaluate preliminary efficacy of the combination therapy. Tumors will be assessed using Investigator read CT/MRI assessments evaluated as per RECIST 1.1, except for patients with GBM who will be assessed per the RANO Criteria. AMENDMENT #2 change: EPR duration modified to 6 months for recurrent GBM patients per the convention for that tumor type

  • Plasma pharmacokinetics (PK) parameters [ Time Frame: In 28-day cycles: Cycle 1/Day 1 and Day 15; Cycle 2/Day 1 and Day 15; then on Day 1 of each additional cycle up to and including cycle 11 (if applicable) ] [ Designated as safety issue: Yes ]
    Plasma PK parameters of LDE225 and plasma PK parameters of BKM120.

Detailed Description:

The primary purpose of this study is to determine a combination maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE) of LDE225 and BKM120 when co-administered orally in patients with advanced solid tumors. Adult patients, aged > 18 years with advanced solid tumors that have progressed despite standard therapy or for which no standard therapies exist will be eligible for this study.

In the dose escalation part of the study, four groups of patients with the following tumor types will be enrolled: recurrent GBM, metastatic breast cancer, metastatic CRC and advanced pancreatic adenocarcinoma. It is anticipated that approximately 45 patients will be enrolled in the dose escalation part. Approximately 15 GBM patients (maximum of 2 patients per dose level) will be enrolled to previously well-tolerated doses during dose escalation if no slot is available in a cohort under active testing. In the dose expansion part of the study, five groups of patients (approximately 15 patients per group) with the following tumor types will be enrolled: recurrent GBM, triple negative metastatic breast cancer, hormone receptor positive (ER+/PR+, and Her2-) metastatic breast cancer, gastric/gastroesophageal junction cancer, and a combined maximum of 15 patients with metastatic CRC or advanced pancreatic adenocarcinoma. The dose expansion will enroll approximately 75 patients. Accounting for patients who may withdraw or who may not meet the eligibility criteria, it is expected that this study will enroll approximately 120 patients.

This is a multi-center, open-label, dose finding, phase Ib study to determine the MTD and/or RDE for the combination of LDE225 plus BKM120, followed by an expansion part to further assess safety and preliminary efficacy of the combination in patients with advanced solid tumors that are frequently associated with dysregulated Hh and/or PI3K pathways, specifically triple negative metastatic breast cancer, hormone receptor positive (ER+/PR+, and Her2-) metastatic breast cancer, advanced pancreatic adenocarcinoma, metastatic CRC, recurrent GBM and gastric/gastroesophageal junction cancer patients. Patients will be treated daily on 28-day cycles. Dose escalation will be dependent on the available toxicity information (including adverse events that are not DLTs), PK, PD, and efficacy information, as well as the recommendations from the Bayesian Logistic Regression Model (BLRM).

AMENDMENT 1 CHANGES:

Inclusion Criteria:

3. Provision of an archival tumor sample to a Novartis designated laboratory for molecular profiling. It is accepted that it may not be possible to obtain all samples prior to commencing study treatment. It is also accepted that it may not be possible to obtain a sample (e.g. if sufficient sample does not exist), and in this situation inclusion of the patient should be discussed with Novartis (as this may not make a patient ineligible).
