DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

VARUBI is a drug used to prevent a delayed form of nausea and vomiting that can occur more than 24 hours after cancer treatment (chemotherapy).

How is this drug used?

VARUBI is a tablet that is taken one to two hours before chemotherapy. It is taken along with other medicines used to prevent nausea and vomiting.
VARUBI should be taken on the first day of each cycle of chemotherapy and not more than one time every 14 days.

What are the benefits of this drug?

Patients taking VARUBI experienced less vomiting and less need for additional medication to treat nausea or vomiting than patients receiving a “sugar pill” (placebo).

Were there any differences in how well the drug worked in clinical trials among sex, race and age?

Subgroup analyses were conducted for sex, race, and age.
  • Sex: VARUBI worked similarly in men and women.
  • Race: VARUBI worked similarly in all races studied.
  • Age: VARUBI worked similarly in patients younger than 65 years and patients 65 years and older.

What are the possible side effects?

The most common side effects are low white cell blood count, poor appetite, hiccups, and dizziness.

Were there any differences in side effects among sex, race and age?

  • Sex: VARUBI had a similar side effect profile in men and women.
  • Race: The number of patients in the non-white subgroups was limited. Therefore, differences in side effects among races could not be concluded.
  • Age: VARUBI had a similar side effect profile in patients below 65 years of age and those 65 years and above.

WHO WAS IN THE CLINICAL TRIALS?

Who participated in the clinical trials?

The FDA approved VARUBI based on evidence from 3 clinical trials of 2595 cancer patients who were receiving chemotherapies known to cause nausea and vomiting. The trials were conducted in Europe, North, Central and South America, Asia and South Africa.
The figure below summarizes how many men and women were in the clinical trials.

How were the trials designed?

There were three trials that evaluated the benefits and side effects of. In two trials patients were receiving chemotherapy which is known to cause nausea and vomiting often, and in one trial they were receiving chemotherapy which causes nausea and vomiting less often. Patients in all three trials were randomly assigned to receive either or placebo drug in addition to their regular medications for nausea and vomiting. Neither the patients nor the health care providers knew which treatment was being given until after the trial was complete.
The trials counted the number of patients who had no vomiting and used no medications for nausea or vomiting from 25 to 120 hours after the first day of the first cycle of chemotherapy, and compared VARUBI and placebo group.

COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
