Efficacy and Safety of Lanreotide Autogel (ATG) in Combination With Temozolomide in Subjects With Thoracic Neuroendocrine Tumors.

Disease Control Rate (DCR) Assessed Locally at Month 9

Time frame · Up to Month 9; for sensitivity analysis-2, up to 10.5 months

Responders were participants who showed disease control according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria v 1.1 assessed locally by the investigator. The DCR was defined as complete response (CR), partial response (PR) or stable disease (SD) according to RECIST criteria v1.1. A sensitivity analysis-1 of local DCR was performed excluding participants withdrawn before 9 months with reason other than progressive disease (PD) or missing assessment and considering participants with PD prior or at 9 months as failures. In addition, a sensitivity analysis-2 was performed in order to consider assessments done between 7.5 and 10.5 months as 9 months assessments when 9-month assessment was missing using same methodology, i.e. considering PD prior or at 9 months and participants withdrawn with other or missing reasons as failures.

DCR Assessed Centrally at Month 9

Time frame · Up to Month 9

The DCR was defined as SD, PR or CR according to RECIST criteria v1.1. A second set of the original computed tomography (CT) scan images were used for a centralized RECIST v1.1 assessment by an independent radiologist.

Median Progression Free Survival (PFS) Assessed Locally and Centrally

Time frame · From Day 1 up to end of study, 52 weeks

The PFS was defined as the time from the first treatment administration to disease progression according to RECIST criteria v 1.1 or death from any cause. The PFS was assessed locally by the investigator and centrally by an independent radiologist. The distribution of PFS times was estimated using the Kaplan-Meier method. The PFS of participants who were lost to follow-up and those who had not progressed at end of study were censored at the date of the last disease assessment.

Median Time to Response (TTR) Assessed Locally and Centrally

Time frame · From Day 1 up to end of study, 52 weeks

The TTR was defined as the time from first treatment administration to the first objective tumor response (PR or CR according to RECIST criteria v 1.1). The TTR was assessed locally by the investigator and centrally by an independent radiologist. The distribution of TTR was estimated using the Kaplan-Meier method. The TTR of participants who were lost to follow-up or died prior to any objective tumor response were censored at the date of the last disease assessment.

Median Duration of Response (DOR) Assessed Locally and Centrally

Time frame · From Day 1 up to end of study, 52 weeks

The DOR was defined as the time from onset of the first objective tumor response (PR or CR) to objective tumor progression (PD) according to RECIST criteria v 1.1. The DOR was assessed locally by the investigator and centrally by an independent radiologist.

Median Time to Progression (TTP) Assessed Locally and Centrally

Time frame · From Day 1 up to end of study, 52 weeks

The TTP was defined as the time from first treatment administration to the first objective tumor progression (PD) according to RECIST criteria v 1.1. The TTP was assessed locally by the investigator and centrally by an independent radiologist. The distribution of TTP times was estimated using the Kaplan-Meier method. The TTP of participants who were lost to follow-up, and those who had not progressed at end of study were censored at the date of the last disease assessment.

Best Overall Response (BOR) Assessed Locally and Centrally

Time frame · From Day 1 up to end of study, 52 weeks

The BOR was defined as the highest OR achieved by the participant from the time of first treatment until disease progression/recurrence or the end of study according to RECIST criteria v1.1 and was classified as: CR \> PR \> Non-CR/Non-progressive disease (NCR/NPD) \> SD \> PD \> ND \> not evaluable (NE). The BOR was assessed locally by the investigator and centrally by an independent radiologist. Percentages are based on the number of participants in the ITT/Safety population with non-missing observations.

Objective Response Rate (ORR) Assessed Locally and Centrally at Months 9 and 12

Time frame · Months 9 and 12

The ORR was defined as the percentage of participants with CR or PR according to RECIST criteria v1.1. The ORR was assessed locally by the investigator and centrally by an independent radiologist. The ORR was based on the participants with PD prior to 9 and 12 months with respectively PD at 9 and 12 months, and participants withdrawn before the assessment for reason other than PD or missing as failures.

DCR Assessed Locally and Centrally at Month 12

Time frame · Month 12

The DCR was defined as SD, PR or CR according to RECIST criteria v1.1. The DCR was assessed locally by the investigator and centrally by an independent radiologist.

DCR Assessed Locally and Centrally at Month 9 by Carcinoid Type

Time frame · Up to Month 9

The influence of type of carcinoid \[typical, atypical and undetermined carcinoid neuroendocrine tumors (NET)\] on the local and central DCR at 9 months was analysed. Typical carcinoids were defined with absent foci of necrosis and mitotic count \< 2 mitoses/2 millimeters\^2 (mm\^2); atypical carcinoids were defined with presence of foci of necrosis and/or 2 mitoses/2 mm\^2 \<= mitotic count \<= 10 mitoses/2 mm\^2; and carcinoid NET were defined as confirmed carcinoid without foci of necrosis and/or mitotic count reported. The DCR was assessed locally by the investigator and centrally by an independent radiologist.

Percentage of Biochemical Responders According to Chromogranin A (CgA) Plasma Levels

Time frame · Baseline (Day 1) and Week 4, 12, 24, 36 and 52

Participants with baseline CgA plasma levels greater than the upper limit of normal (ULN) were assessed for a biochemical response. A biochemical responder was defined as a participant who had a decrease of CgA \>= 50% compared to baseline, while biochemical SD was defined as a decrease \< 50% or an increase \<= 25% compared to baseline. Biochemical non-responders had an increase \>25% compared to baseline. Baseline was defined as value at Day 1.
