The record lists 9 sites in United States, Czechia, France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Estimated Steady-State Maximum Plasma Concentration (Cmax,ss) of Sunitinib and Its Metabolite (time frame: pre-dose on Day 1, Day 12-18 and Day 25-29 of Cycle 1,2, 3 and 2, 4, 6, 8 hours post-dose on Day 1 Cycle 1). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01396148, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
