Exclusion Criteria:

Focal radiation therapy within 4 weeks before first dose of study treatment, or full spinal radiotherapy within 3 months before first dose of study treatment.
Patients who have neuromuscular disorders that are associated with elevated CK (eg, inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy).
Patients receiving treatment with medications that are known to be strong inhibitors or inducers of CYP3A4/5 or are metabolized by CYP2B6 and CYP2C9, that have narrow therapeutic indices that cannot be discontinued at least 2 weeks before first dose of study treatment and for the duration of the study
Patients receiving unstable or increasing doses of corticosteroids. If patients are on corticosteroids for endocrine deficiencies or tumor-associated symptoms, dose must have been stabilized (or decreasing) for at least 5 days before first dose of study treatment.

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Sonidegib (LDE225)

Temozolamide (TMZ)

Arm Description

150 to 200 mg/m2 for 5 sequential days every 4 weeks according to prescribing information until the study was amended to a single arm study.

Outcomes

Primary Outcome Measures

Percentage of Participants With Overall Response Rate (ORR) According to Independent Review Committee (IRC) From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

ORR was defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR) (as per tumor response guidelines and criteria for Medulloblastoma). The IRC evaluated all radiological images and applicable clinical data (i.e., neurological examination, steroid use and cerebrospinal fluid (CSF) results as applicable). Assessments after crossover were not included for TMZ participants.

Secondary Outcome Measures

Progression Free Survival (PFS) According to IRC From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

PFS was defined as the time from date of randomization to the date of event defined as the first documented progression or death due to any cause (as per tumor response guidelines and criteria for Medulloblastoma). The IRC evaluated all radiological images and applicable clinical data (i.e., neurological examination, steroid use and cerebrospinal fluid (CSF) results as applicable). TMZ participants without event prior to crossover were censored.

PFS According to Local Investigator Assessment From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

PFS was defined as the time from date of randomization to the date of event defined as the first documented progression or death due to any cause. PFS was evaluated by local Investigator assessment per tumor response guidelines and criteria for Medulloblastoma.

Percentage of Participants With ORR According to Local Investigator Assessment From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

ORR was defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR). ORR was evaluated by local Investigator assessment per tumor response guidelines and criteria for Medulloblastoma. Assessments after crossover were not included for TMZ patients.

Duration of Response (DoR) According to Local Investigator Assessment From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

DoR was defined as the time from the first documented onset of confirmed PR or CR to the date of PD/relapse or death due to medulloblastoma. DoR was evaluated by local Investigator assessment per tumor response guidelines and criteria for Medulloblastoma. TMZ participants without an event prior to crossover were censored.

Overall Survival (OS) From Date First Participant Randomized, 13-Sep-2013 to Date of Data Cut-off, 15-Nov-2016

OS was defined as the time from date of randomization to date of death due to any cause. All deaths are considered, including deaths occurred after crossover for TMZ participants.

Pharmacokinetics (PK): Summary of Plasma Trough Concentrations for Sonidegib (LDE225)

Blood samples were collected for assessment. The children's group was analyzed up until week 25 only.

Brief Summary

This Phase II study evaluated the safety and efficacy of LDE225 in adult and pediatric patients with Hh-pathway activated, relapsed MB.

Detailed Description

This study was a single-arm study of the efficacy and safety of oral sonidegib in patients with Hh-pathway activated relapsed medulloblastoma. It was initially designed as a randomized, controlled, open-label phase III study of adults and children with Hh-pathway activated MB whose disease had failed standard of care therapy, including radiation therapy (RT). The original study consisted of a randomized controlled part and a non-randomized uncontrolled part. Approximately 69 patients were to be randomized in a 2:1 ratio to receive sonidegib oral suspension or the active control, temozolomide (TMZ) capsules. Randomization was to be stratified according to age, <18 years versus ≥ 18 years. Approximately 40 patients were to receive sonidegib in the non-randomized uncontrolled part of the study. Following the enrollment of 11 patients, the study was amended to become a phase II single-arm study with only sonidegib, and the target enrollment was changed to 20 patients. Prior to the study amendment, TMZ participants whose disease progressed while on TMZ were permitted to crossover to sonidegib. After the amendment, participants receiving TMZ were crossed over to sonidegib.
