Treatment Patterns and Outcomes in GEP NET: A Retrospective Observational Cohort Study (PRIME Initiative)
Overview
This study aims to characterize current treatment patterns and clinical outcomes among newly diagnosed GEP-NET patients in the United States using open-source Longitudinal Prescription Claims (LRx) and Patient Centric Medical Claims (Dx) databases supplemented with mortality data.
Primary outcome measures
- Number of Lines of Therapy (LOTs) [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients by Treatment Regimen per LOT [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients by Type of Therapy in Each LOT [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients who Discontinue all Medications Within the 1L Treatment Regimen [Time frame: Up to approximately 8 years]
- Number of Cycles of Medications Within the Treatment Regimen Before Discontinuation [Time frame: Up to approximately 8 years]
- Time to 1L Treatment Discontinuation [Time frame: Up to approximately 8 years]
Secondary outcome measures (10)
- Duration Between GEP-NET Diagnosis and 1L Treatment [Time frame: Baseline]
- Number and Percentage of Patients who Switch Treatment From 1L to Fifth-line (5L) Treatment [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients With Addition of Other Therapies While on Initial 1L Therapy [Time frame: Up to approximately 8 years]
- Time to Next Treatment (TTNT) [Time frame: Up to approximately 8 years]
- Overall Survival (OS) [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients by Demographics [Time frame: Baseline]
- Age [Time frame: Baseline]
- Duration of Follow-up [Time frame: Up to approximately 8 years]
- Number and Percentage of Patients by Clinical Characteristics [Time frame: Baseline]
- NCI Comorbidity Index Score [Time frame: Baseline]
Eligibility criteria
Inclusion criteria
- Patients with ≥1 International Classification of Diseases Clinical Modification, 10th revision (ICD-10-CM) diagnosis code for GEP-NET between 01 January 2018 and 31 December 2025. The date of the first such claim will be defined as the diagnosis date.
- Initiation of first-line (1L) systemic therapy (i.e., somatostatin analogs \[SSAs\], targeted therapy, peptide receptor radionuclide therapy \[PRRT\], chemotherapy) indicated for GEP-NET on or after the date of diagnosis. The date of treatment initiation will be defined as the index date.
- Patients ≥18 years of age on the index date
- Patients with ≥12 months (360 days) of continuous data availability (proxy for continuous health plan enrollment) prior to the index date, defined as:
- ≥1 medical and pharmacy claim >12 months prior to the index date; AND
- ≥1 medical and pharmacy claim within the first 6 months of the 12-month period prior to the index date; AND
- ≥1 medical and pharmacy claim during the last 6 months of the 12-month period prior to the index date; AND
- Patients with ≥1 month (30 days) of continuous data availability (proxy for continuous health plan enrollment) following the index date, defined as:
- ≥ 1 pharmacy dispensing a GEP-NET treatment at any time during the post-index period, including the index date, reports data during the first month following the index date
- ≥ 1 provider prescribing a GEP-NET treatment at any time during the post-index period, including the index date, reports data during the first month following the index date
