New treatment option for Neuroendocrine Tumors
Official title Lenvatinib Plus Pembrolizumab in Well Differentiated G3 Neuroendocrine Tumors
ClinicalTrials.gov ID: NCT05746208
What this study is testing
What is Lenvatinib?
Lenvatinib is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for neuroendocrine tumors.
Also referred to as Lenvima.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is the first study to be done in a newly described class of neuroendocrine tumors known as well-differentiated grade 3 neuroendocrine tumors (WD G3 NET). First described in the pancreas in 2017, the classification was broadened to include gastrointestinal tract tumors in 2019.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
