How Was BALVERSA® Studied?
BALVERSA® Clinical Study Details
BALVERSA® was studied in 87 adults with advanced bladder cancer who had tried at least 1 chemotherapy
In the clinical trial for BALVERSA®, all patients had a tumor that tested positive for a certain type of abnormal FGFR gene. Everyone started on an 8-mg once-daily dose of BALVERSA®.
After about 2 weeks, all patients had a blood test to measure their phosphate levels. People with higher phosphate levels stayed at the 8-mg dose, while those with lower levels increased their dose to 9 mg once a day.
People stayed on BALVERSA® until their tumors started to grow or until they had side effects that were too severe.
In the study, BALVERSA® helped reduce the growth of tumors in patients who had an objective response
Remember, each person is different, so the results you see with BALVERSA® may not be the same as in the study.
- 32.2% of patients (28 out of 87) experienced a certain amount of tumor shrinkage (called an “objective response rate,” or ORR) 87 people were included in the assessment of ORR2.3% (2 out of 87) had a complete response and 29.9% (26 out of 87) had a partial response
- Patients who had an objective response had their tumor shrinkage last for a median of 5.4 months. This means that for 50% of the patients, the response lasted for 5.4 months or longer, and for the other 50% of the patients, it was shorter than 5.4 months
See glossary for definitions of “objective response rate,” “complete response,” “partial response,” and “median.”
