TIBSOVO clinical trial

TIBSOVO TRIAL RESULTS IN
CHOLANGIOCARCINOMA (CCA)

TIBSOVO was studied in a clinical trial involving 185 adult patients with an IDH1 mutation whose disease had progressed after previous
treatments. The purpose of the trial was to determine how long patients who received TIBSOVO lived without their CCA getting worse.

The trial studied patients who:

  • Had their cancer get worse after receiving at least 1 but not more than 2 previous treatments
  • Had disease that spread
  • Had an IDH1 mutation

TIBSOVO has been shown to increase the length of time a person can live with CCA without it getting worse.

Benefits of TIBSOVO

BENEFITS OF TIBSOVO

In the trial, TIBSOVO helped to slow the progression of CCA

People treated with TIBSOVO achieved better control of their CCA vs. people who received placebo

One year.

Patients treated with TIBSOVO were less likely to experience disease progression or die during the first year of treatment

More than half of the patients who took TIBSOVO achieved stable disease, which means their CCA did not continue to spread, vs. 28% of patients who received placebo

51 percent TIBSOVO.
28 percent placebo.

Patients taking TIBSOVO had higher rates of stable disease than those who took placebo.

  • numbness and pain on one side or both sides of your body
  • any changes in your ability to see, touch, hear, or taste
  • burning or prickling sensation
  • difficulty breathing

The most common side effects of TIBSOVO in adults with cholangiocarcinoma include:

  • fatigue
  • nausea
  • abdominal pain
  • diarrhea
  • cough
  • decreased appetite
  • fluid and swelling in your stomach area
