Approval date: December 23, 2019


DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

UBRELVY is a drug used for the acute treatment of migraine with or without aura in adults.

A migraine is a type of headache that, in addition to pain, can be associated with nausea, vomiting, and sensitivity to light or sound. Some patients may experience an aura, which may consist of temporary visual, or other symptoms, shortly before the onset of the headache.

How is this drug used?

UBRELVY is a tablet taken by mouth as needed. A second tablet may be taken two hours after the first one, if needed.

What are the benefits of this drug?

A higher percentage of patients did not have a headache two hours after taking UBRELVY compared to patients who took a placebo. Also, a higher percentage of patients who took UBRELVY did not have their most bothersome migraine-associated symptom (e.g., light sensitivity, sound sensitivity, or nausea) two hours after taking the drug, in comparison to patients who received placebo.

What are the benefits of this drug (results of trials used to assess efficacy)?

The figures below summarize efficacy results for the pooled patients from Trials 1 and 2. The primary outcome measures were pain freedom and most bothersome symptom (MBS) freedom at 2 hours post-dose.

UBRELVY Prescribing Information

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

  • Sex: UBRELVY worked similarly in men and women.
  • Race: UBRELVY worked similarly across racial groups.
  • Age: UBRELVY worked similarly among patients younger and older than 40 years of age. The number of patients 65 years and older was limited; therefore, differences in how UBRELVY worked between patients younger and older than 65 years of age could not be determined.

WHO WAS IN THE CLINICAL TRIALS?

Who participated in the clinical trials?

The FDA approved UBRELVY based on evidence from two clinical trials (Trial 1/NCT02828020 and Trial 2/NCT02867709) of 2423 patients with migraine headaches. Trials were conducted at 188 sites in the United States.

Adapted from FDA Review

How were the trials designed?

The efficacy and safety of UBRELVY were evaluated in two trials of patients with migraine headache with or without aura.

Patients were instructed to treat moderate to severe migraine headache pain with one dose of UBRELVY or placebo. Neither the patients nor the health care providers knew which treatment was being given until after the trials were completed. A second dose of the same medication or the patient’s usual treatment for migraine was allowed between 2 to 48 hours after the initial treatment.

The benefit of UBRELVY was assessed based on the percentage of patients who became pain free within 2 hours and comparing it with placebo treated patients. The assessment also included the percentage of patients who were free of their associated most bothersome migraine symptom within 2 hours of taking the trial drug.

How were the trials designed?

The efficacy and safety of UBRELVY were evaluated in two randomized, placebo controlled, double blind trials of patients with migraine headaches with or without aura.

Patients were instructed to treat a migraine with moderate to severe headache pain intensity with one dose of trial medication (UBRELVY or placebo). A second dose of trial medication or the patient’s usual acute treatment for migraine, was allowed between 2 to 48 hours after the initial treatment for a non-responding or recurrent migraine headache.

The primary efficacy endpoints were identical for both trials: pain freedom and most bothersome symptom (MBS) freedom at 2 hours post-dose.

GLOSSARY

CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
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.
