Study design details

Study design

Prospective, multicentre, non-interventional, single-arm study conducted in Germany and Austria with 150 adult participants with pNET or epNET. Observational period: up to 18 months wich includes 3-month follow-up if treatment discontinued.

Main study objective

To describe the effectiveness of cabozantinib tablets in participantswith previously treated neuroendocrine tumours (NETs) in real-life in terms of disease control rate (DCR) at 6 months of cabozantinib treatment as assessed by the treating physician.

Outcomes

Primary Outcome Measure:
- Disease Control Rate (DCR) at 6 Months
Secondary Outcome Measure:
- Objective Response Rate (ORR) up to 18 Months
- Change from baseline in global and subscale scores of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30), at baseline and Every 3 Months up to 18 Months.
- Change from baseline in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Gastrointestinal Neuroendocrine Tumors Module (EORTC QLQ-GINET21), baseline and Every 3 Months up to 18 Months
- Percentage of participants experiencing Adverse Events (AEs), non-serious, drug-related, or serious Adverse Events (SAEs), up to 18 Months
- Frequency of Dose Modifications Due to Adverse Events, up to 18 months
- Duration of treatment (DoT), up to 18 Months
- Proportion of participants switching to a new line of therapy and type of therapy received, up to 18 Months
- Disease Control Rate After Switch to Next Line of Therapy, 3 Months After Therapy Switch
- Chromogranin A Levels, baseline and Every 3 Months up to 18 Months
- Neuron-Specific Enolase blood levels, baseline and Every 3 Months up to 18 Months
- Time to next treatment (TTNT), up to 18 Months
- Progression-Free Survival (PFS), up to 18 Months
- Progression-Free Survival Rate at 12 and 18 Months

Data analysis plan

In this non-interventional study, all the analyses will be primarily descriptive in nature.
The primary endpoint will be DCR of cabozantinib-treated NET participants; the rate of disease control will be presented with the 95% confidence interval (CI). Secondary endpoints, i.e. ORR, QoL, safety, DCR of subsequent treatment, DoT, as well as TTNT will be presented descriptively. The Kaplan-Meier method will be used to obtain the estimates of median PFS (time between the start of treatment with cabozantinib until progression assessed clinically or via imaging as observed by the treating physician or death from any cause) and their associated two-sided 95% CIs or landmark 12-month and 18-month PFS.
Subgroup analyses will be only performed if data permit and subgroups may be merged into larger subgroups if deemed necessary. The subgroups will be based of NET localization (Lung NET, Gastro-Intestinal NET, pNET and other NET).
