DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

OZEMPIC is a drug that improves blood sugar control in adults with type 2 diabetes mellitus (DM) when used in addition to diet and exercise.

How is this drug used?

OZEMPIC is available as a liquid that comes in a prefilled pen. It is injected once weekly under the skin (subcutaneously) of the abdomen, thigh or upper arm. OZEMPIC may be used alone or in combination with other FDA-approved diabetes medications such as metformin, sulfonylureas, thiazolidinedione and insulin. In patients also using insulin injections, OZEMPIC and insulin should be injected separately and not mixed.

What are the benefits of this drug?

In patients with type 2 diabetes, treatment with OZEMPIC can lower HbA1c (hemoglobin A1c), which is a measure of blood sugar control.

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

The FDA considered the results of five randomized, multinational clinical trials to evaluate the efficacy of OZEMPIC in the treatment of adult patients with type 2 diabetes mellitus. In these trials, OZEMPIC was used as monotherapy, or in combination with oral antidiabetic medications with or without basal insulin, and compared to placebo, sitagliptin, exenatide extended release and insulin glargine. The primary efficacy endpoint in each trial was change in HbA1c from baseline. The results of each trial are presented in the tables below.

FDA Statistical Review

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

  • Sex: Overall, OZEMPIC worked similarly in men and women
  • Race: OZEMPIC worked similarly in White, Black/African American and Asian races. The number of patients of other races was small; therefore, differences in response could not be determined.
  • Age: OZEMPIC worked similarly in patients younger or older than 65 years of age.

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

Tables 9, 10, 11, and 12 summarize the effect of OZEMPIC on HbA1c by subgroup in the clinical trials.

FDA Statistical Review

What are the possible side effects?

OZEMPIC may cause serious side effects including low blood sugar, inflammation of the pancreas, complications of diabetes-related retina disease (diabetic retinopathy) and allergic reactions. In animal studies, mice and rats that received OZEMPIC were more likely to develop a certain kind of thyroid cancer. It is not known whether this may occur in humans.

The most common side effects in clinical trials included nausea, vomiting, diarrhea, abdominal pain and constipation.

What are the possible side effects (results of trials used to assess safety)?

Table 13 summarizes common adverse reactions (excluding hypoglycemia) from two placebo-controlled trials. OZEMPIC was used alone in one trial and in combination with basal insulin in the other trial.

FDA Prescribing Information

The types and frequency of common adverse reactions, excluding hypoglycemia, in other trials were similar to those listed in Table 13.

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

  • Sex: The risk of side effects was similar between men and women.
  • Race: The risk of side effects was similar between White, Black/African American and Asian races. The number of patients of other races was small; therefore, differences could not be determined.
  • Age: The risk of side effects was similar between patients younger or older than 65 years of age.

Were there any differences in side effects of the clinical trials among sex, race, and age groups?

WHO WAS IN THE STUDIES?

Who participated in the clinical trials?

The FDA approved OZEMPIC based on evidence from seven clinical trials of 4087 patients with type 2 DM. The trials were conducted at 536 sites in 33 countries, including Canada, Mexico, Russian Federation, Ukraine, Turkey, India, South Africa, Japan, Hong Kong, multiple European countries, Argentina, and the United States.

The FDA also considered data from one separate trial of 3297 patients with type 2 DM who were at high risk for cardiovascular events. This trial was conducted in 20 countries in Europe, Russian Federation, Turkey, Brazil, Israel, Malaysia, Brazil, Mexico, Thailand, Taiwan, Canada, and the United States.

These two populations will be presented separately.

How were the trials designed?

The benefits and side effects of OZEMPIC for the treatment of adult patients with type 2 DM were evaluated in seven clinical trials. In two of these trials (NCT #02054897 and NCT#02305381), patients were randomly assigned to receive either OZEMPIC or placebo injection weekly. Neither the patient nor the health care provider knew which treatment was being given until after the trials were completed. Treatment was given for 30 weeks.

In the other five trials (NCT #01930188, 01885208, 02128932, 02207374, 02254291), patients were randomly assigned to receive either OZEMPIC or another antidiabetic medication, and the patient and provider knew which medication was being given in four trials. Treatment was given for 30 weeks or 56 weeks.

In each trial, HbA1c was measured from the start of the trial to the end of the trial and compared between the OZEMPIC group and the other groups.

There was also an additional trial where patients with type 2 diabetes who were at high risk for cardiovascular events (NCT #01720446) were randomly assigned to receive OZEMPIC or placebo. Neither the patient nor the health care provider knew which treatment was being given. Treatment was given for 104 weeks (2 years), and the occurrence of cardiovascular events, including heart attacks, strokes and hospitalization due to unstable angina (near heart attack) were recorded and compared in the two groups of patients.

How were the trials designed?

The efficacy of OZEMPIC was evaluated in 5 trials.

Two randomized, double-blind, placebo-controlled, multinational clinical trials evaluated the efficacy of two doses of OZEMPIC as monotherapy or in combination with basal insulin. The primary endpoint was change in HbA1C from baseline to week 30.

Three additional randomized, active-controlled, multinational, non-inferiority design clinical trials evaluated the efficacy of two doses of OZEMPIC added to other antidiabetic medications and compared to either sitagliptin, exenatide ER, or insulin glargine. The trial that compared OZEMPIC to sitagliptin was double-blind, whereas the other two active-controlled trials were open-label.

Safety of OZEMPIC was evaluated in the above five trials and two additional trials conducted in Japan. Both Japanese trials were randomized, open-label, active-controlled trials in which OZEMPIC was added to other antidiabetic medications.

An additional randomized, double-blind, placebo-controlled, multinational trial was conducted in patients at high risk of cardiovascular events. The primary endpoint was time to first occurrence of a major atherosclerotic cardiovascular event (MACE), defined as any of the following events: cardiovascular death, myocardial infarction, or stroke.

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.
