DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
VERZENIO is a drug for treatment of a specific form of breast cancer called hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer.
VERZENIO is used in combination with fulvestrant (another drug used to treat breast cancer) when the breast cancer worsened after hormonal therapy.
VERZENIO is taken alone when the breast cancer worsened after hormonal therapy and chemotherapy.
VERZENIO is used in combination with fulvestrant (another drug used to treat breast cancer) when the breast cancer worsened after hormonal therapy.
VERZENIO is taken alone when the breast cancer worsened after hormonal therapy and chemotherapy.
How is this drug used?
VERZENIO tablet of 150 mg is taken twice daily in combination with fulvestrant . VERZENIO tablet of 200 mg is taken twice daily when used alone.
What are the benefits of this drug?
The first trial measured the length of time tumors did not grow after treatment (progression-free survival). The progression-free survival for patients taking VERZENIO with fulvestrant was about 16 months compared to 9 months for patients taking a placebo with fulvestrant.
The second trial measured the percent of patients whose tumors completely or partially shrank after treatment (objective response rate). In the trial, approximately 20 percent of patients taking VERZENIO experienced complete or partial shrinkage of their tumors that lasted about 9 months.
The second trial measured the percent of patients whose tumors completely or partially shrank after treatment (objective response rate). In the trial, approximately 20 percent of patients taking VERZENIO experienced complete or partial shrinkage of their tumors that lasted about 9 months.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: The trial included only women therefore sex differences cannot be determined.
- Race: The majority of patients were white. The number of patients in other races was limited; therefore, differences in response among races could not be determined.
- Age: VERZENIO worked similarly in patients above and below 65 years of age.
What are the possible side effects?
VERZENIO may cause serious side effects, including severe diarrhea, low white blood cell counts (neutropenia), liver damage and blood clots in veins and lungs.
The most common side effects include diarrhea, nausea, abdominal pain, infections, tiredness, low blood counts, decreased appetite, vomiting, and headache.

- Race: The majority of patients were white. The number of patients in other races was limited; therefore, differences in side effects among races could not be determined.
- Age: The incidence of overall side effects was similar in patients above and below 65 years of age.
Who participated in the clinical trials?
The FDA approved VERZENIO based on evidence from two clinical trials that enrolled women with HR-positive, HER2-negative advanced breast cancer.
Patients in Trial 1 (NCT02107703) had an advanced breast cancer that progresed after hormone therapy. The trial was conducted at 145 sites in North America, Europe and Asia.
Patients in Trial 2 (NCT 02102490) had an advanced breast cancer that progresed after hormone and chemo therapy . The trial was conducted at 35 sites in US and Europe.
Figures 1a and 1b summarizes how many women were in the clinical trials.

How were the trials designed?
There were two trials that evaluated benefits and side effects of VERZENIO in patients with advanced HR-positive, HER2-negative breast cancer. Each trial was designed differently.
In the first trial, patients had breast cancer that had progressed after treatment with hormone therapy and had not received chemotherapy once the cancer had metastasized. Patients received, at random, either VERZENIO in combination with fulvestrant or placebo in combination with fulvestrant. The treatment continued until the disease progressed or the side effects became too toxic. Neither the patients nor the health care providers knew which treatment was being given until the trial was completed.
The trial measured the length of time tumors did not grow after treatment (progression-free survival).

In the second trial patients had breast cancer that had progressed after treatment with hormone therapy and also have received chemotherapy after the cancer metastasized. All patients received VERZENIO. The treatment continued until the disease progressed or the side effects became too toxic.
The trial measured the percent of patients whose tumors completely or partially shrank after treatment (objective response rate).

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.
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.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
