Outcomes

Primary Outcome Measures

Disease Control Rate (DCR) After 6 Months
All tumour assessments were performed using the Response Evaluation Criteria In Solid Tumours (RECIST) criteria (1.1). Computer Tomography (CT-scan) or Magnetic Resonance Imaging (MRI) could be used for as method of tumour measurement and the same method of tumour measurement was used throughout the study for each subject. CT scans/MRI were performed at screening or baseline visit then at weeks 12, 24 and at early withdrawal or at anytime during the study in the case of any clinical or biological signs of tumour progression. The DCR was defined as the proportion of subjects with a response of CR, PR or SD after 6 months of combination treatment and was described in the ITT population along with its 95% Confidence Interval (CI) and was compared to 45% with an exact binomial proportion test. The Last Observation Carried Forward (LOCF) method was used to replace missing assessments at the end of the combination phase.

Secondary Outcome Measures

DCR After 12 Months
All tumour assessments were performed using the RECIST criteria (1.1). CT-scan or MRI could be used for as method of tumour measurement and the same method of tumour measurement was used throughout the study for each subject. CT scans/MRI were performed at screening or baseline visit then at baseline, weeks 12, 24, 36, 48 (end of study) and at study withdrawal or at anytime during the study in the case of any clinical or biological signs of tumour progression. The DCR was defined as the proportion of subjects with a response of CR, PR or SD after 6 months combination treatment followed by either 6 months of lanreotide ATG 120 mg maintenance treatment or no treatment. The DCR was described in the ITT population along with its 95% CI and was compared to 45% with an exact binomial proportion test. The LOCF method was used to replace missing assessments at the end of the maintenance phase.
Progression-Free Survival (PFS) Within 12 Months
PFS was defined as the time from the date of treatment start to the date of the first documented disease progression or death due to any cause within the first 12 months of treatment. If a subject had not progressed or died after 12 months of treatment or when any further anti-neoplastic therapy was received, PFS was censored at the time of the last tumour assessment before the analysis cut-off date or the anti-neoplastic therapy date. A Kaplan-Meier estimate of the PFS was calculated to determine the number of subjects at risk. Median PFS time (50% of subjects who would not progress or die) of the ITT population is presented along with 95 % CI.
Time To Response (TtR) Within 12 Months
TtR was defined as the time from the date of treatment start to the date of the first documented objective response (CR or PR) within the first 12 months of treatment (combination and maintenance phases). A Kaplan Meier estimate of the TtR survival function was constructed. The Kaplan-Meier method was used to estimate the median TtR and its 95% CI for subjects in the ITT population (50% of subjects were expected to have a CR or PR at this time).
Duration of Response (DoR) Within 12 Months
The DoR is an estimation of the time from first documented objective response (CR or PR) to the first date of progressive disease (PD) or death due to disease progression for subjects who experienced an objective response within the first 12 months of treatment (combination and maintenance phases). The Kaplan-Meier method was used to estimate the median DoR and its 95% CI for subjects in the ITT population who had an objective response.
The Number of Subjects With a Biochemical Response Using Chromogranin-A (CgA) Levels After 6 Months
Blood samples for CgA blood tumour marker analysis were taken at baseline, weeks 12, 24 and at early withdrawal. The biochemical response after 6 months combination treatment was estimated for subjects with abnormal CgA levels at baseline.

Pharmacokinetic (PK) Results: Lanreotide ATG 120 mg Serum Concentrations Within 12 Months
Lanreotide ATG levels were measured in a subset of subjects to evaluate if temozolomide co-treatment had an impact on lanreotide serum concentration over a 12 month period. Blood samples were collected for the determination of lanreotide ATG in serum at baseline, weeks 4, 12, 24 and 48 (end of study). The concentrations of lanreotide ATG in serum were determined by a validated radioimmunoassay analysis method with a lower limit of quantitation of 0.08 nanograms [ng]/mL). Serum concentrations of lanreotide ATG at each of the time points in the combination and maintenance phase are presented. Only subjects with data available for analysis are presented.

Title
Pharmacokinetic (PK) Results: Lanreotide ATG 120 mg Serum Concentrations Within 12 Months
Description
Lanreotide ATG levels were measured in a subset of subjects to evaluate if temozolomide co-treatment had an impact on lanreotide serum concentration over a 12 month period. Blood samples were collected for the determination of lanreotide ATG in serum at baseline, weeks 4, 12, 24 and 48 (end of study). The concentrations of lanreotide ATG in serum were determined by a validated radioimmunoassay analysis method with a lower limit of quantitation of 0.08 nanograms [ng]/mL). Serum concentrations of lanreotide ATG at each of the time points in the combination and maintenance phase are presented. Only subjects with data available for analysis are presented.
Time Frame
