A NEW STUDY FORPeople Living With Advanced or Metastatic Neuroendocrine Tumors

About STELLAR-311
STELLAR-311 is a The purpose of the study is to find out how a (zanzalintinib) works compared to an approved drug (everolimus) as a potential treatment for neuroendocrine tumors that cannot be removed by surgery or have spread to other parts of the body (metastatic).
Research studies help scientists and doctors learn more about medical conditions and study drugs. This study will help researchers learn if the study drug is safe and if it works to treat neuroendocrine tumors in many different types of people.

Participation = Representation
It is important that diverse groups of people take part in research studies. Studies should include people of different ages, sexes, races, and ethnicities. Having diverse groups represented in research helps show if study drugs are safe and work well for all types of people likely to use the drug(s).

People from different backgrounds can experience the same disease differently. Diversity in research studies can help us understand and address these types of differences.
Learn More About the Study
People enrolled in STELLAR-311 will be randomly assigned to one of two treatment groups by chance. Each group will receive either the study drug or everolimus. People will know which group they are assigned to and which study drug they will receive.
Volunteering for a study is a personal choice. We encourage people from all backgrounds to consider joining the STELLAR-311 clinical trial. Talk with a healthcare professional you trust about clinical trials as a treatment option.

Group A
People in this group will receive the study drug: zanzalintinib.


Group B
People in this group will receive a medicine approved for neuroendocrine tumors: everolimus.
People in the study will be assigned to a treatment group. One group will receive the study drug zanzalintinib and the other group will receive the standard treatment of everolimus.
A computer will randomly assign each person to a treatment group by chance:
Group A will get zanzalintinib.
Group B will get everolimus.
ZANZALINTINIB HAS NOT BEEN APPROVED BY REGULATORY AUTHORITIES. THE SAFETY AND EFFECTIVENESS OF ZANZALINTINIB HAVE NOT BEEN ESTABLISHED AND ARE BEING STUDIED AS PART OF THIS CLINICAL TRIAL.
