DRUG TRIALS SNAPSHOT SUMMARY:

What is the drug for?

STEGLATRO is a drug that improves blood sugar control in adults with type 2 diabetes when used in addition to diet and exercise.

How is this drug used?

STEGLATRO is a tablet that is taken by mouth once daily in the morning.

What are the benefits of this drug?

In patients with type 2 diabetes treatment with STEGLATRO can lower hemoglobin A1c (HbA1c). HbA1c is a measure of blood sugar control over the last 8-12 weeks.

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

The efficacy of STEGLATRO as monotherapy, in addition to diet and exercise is presented in the table below. The primary efficacy endpoint was the change in HbA1c from the start of each trial.

Missing Week 26 measurements were imputed using multiple imputation with a mean equal to the baseline value of the patient. Results include measurements collected after initiation of rescue medication. For those patients who did not receive rescue medication and had values measured at 26 weeks, the mean changes from baseline for HbA1c were -0.1%, -0.8%, and -1.0% for placebo, STEGLATRO 5 mg, and STEGLATRO 15 mg, respectively.

STEGLATRO Prescribing Information

The following trials presented below were also used to support approval of STEGLATRO:

  • Active-Controlled Trial (NCT020991110) of STEGLATRO in Combination with Sitagliptin versus STEGLATRO Alone and Sitagliptin Alone, as Add-on to Metformin
    A total of 1,233 patients received treatment for 26 weeks. After 26 weeks of treatment, the STEGLATRO 5 mg or 15 mg + sitagliptin 100 mg demonstrated statistically significant greater reductions in HbA1c compared to STEGLATRO (5 mg or 15 mg) alone or sitagliptin 100 mg alone.
  • Placebo-Controlled Trial (NCT02226003) of STEGLATRO Combination Therapy with Sitagliptin
    A total of 291 patients received treatment for 26 weeks. After 26 weeks of treatment, STEGLATRO 5 mg and 15 mg, in combination with sitagliptin at 100 mg, demonstrated statistically significant reductions in HbA1c compared to placebo.
  • Placebo-Controlled Trial (NCT01986855) of STEGLATRO in Patients with Moderate Renal Impairment, as Add-on to Antidiabetic Therapy
    A total of 468 patients with type 2 2DM, who had moderate renal impairment, received treatment for 26 weeks. Treatment with STEGLATRO did not result in statistically significant reductions in HbA1c compared to placebo.

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

  • Sex: STEGLATRO worked similarly in men and women.
  • Race: The majority of patients were White. The number of patients of other races was limited; therefore, differences in response among races could not be determined.
  • Age: STEGLATRO worked similarly in patients below and above 65 years of age.

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

Table 6 below summarizes the results for the primary efficacy endpoint, the change in HbA1c by sex, age, and race for a pool of 4 of the 7 controlled trials (NCT01958671, NCT02099110, NCT02036515, and NCT02033889).

FDA Statistical Review

What are the possible side effects?

STEGLATRO may cause serious side effects such as decrease in blood pressure, kidney injury, surgery to remove lower limbs, increased cholesterol levels, and very low blood sugar levels when used in combination with insulin or medications that increase insulin, and serious urinary tract infection. Serious urinary tract infections can spread to the kidneys (pyeleonephritis) or cause a serious, potentially life-threatening blood infection (urosepsis).

STEGLATRO may also cause ketoacidosis. Diabetic ketoacidosis is a serious, potentially life-threatening complication that occurs when the body produces high levels of acids in the blood. The acids are called ketones.

The most common side effects with STEGLATRO are genital yeast infections.

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

The table below summarizes common adverse reactions for the safety population from the 3 placebo-controlled trials. Demographics of this population are presented in Table 10 under MORE INFO section.

STEGLATRO Prescribing Information

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

  • Sex: More genital yeast infections were seen in women taking STEGLATRO compared to men taking STEGLATRO. In the trial, all patients (men and women) treated with STEGLATROI had more genital yeast infections compared to patients given placebo.
  • Race: The majority of patients were White. The number of patients of other races was limited; therefore, differences in side effects among races could not be determined.
  • Age: Patients above 65 years of age had more side effects related to dehydration compared to younger patients.

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

STEGLATRO Prescribing Information

WHO WAS IN THE CLINICAL TRIALS?

Who participated in the clinical trials?

The FDA approved STEGLATRO based on evidence from seven clinical trials (NCT01958671, NCT02033889, NCT02036515, NCT01986855, NCT01999218, NCT02099110, and NCT02226003) of 4,859 patients with type 2 diabetes. Trials were conducted at 387 centers in Asia, Australia/New Zealand, Europe, North America, South Africa, and South America.

Five of the trials (NCT02033889, NCT02036515, NCT01999218, NCT02099110, and NCT02226003) provided support for approval of two new combination drug products (Segluromet and Steglujan) that contain STEGLATRO in combination with the approved antidiabetic drugs metformin and sitagliptin, respectively.

Presented below is the population of 4,859 patients with type 2 diabetes that participated in all 7 trials together. Three of the trials (NCT01958671, NCT02036515, and NCT02033889) were used to evaluate the side effects of STEGLATRO and represent the safety population. Demographics of these patients are presented in Table 10 under MORE INFO section.

Clinical Summary Report

How were the trials designed?

The benefits and side effects of STEGLATRO were evaluated in seven clinical trials of adults with type 2 diabetes whose disease was not well controlled. All patients were required to follow diet and exercise recommendations, but the trials differed with respect to which other drugs patients were allowed to use for diabetes treatment.

In five trials, patients were randomly assigned to receive either STEGLATRO or placebo by mouth once daily; and, in two trials, they received either STEGLATRO or an active comparator. Neither the patients nor the healthcare providers knew which treatment patients received until after the trial was completed. Treatment was given for 26 weeks for six of the trials, and for 52 weeks for one trial.

The benefit of STEGLATRO was evaluated by the change in HbA1c between the STEGLATRO and the other treatment (either placebo or active comparator) at the end of the treatment period.

How were the trials designed?

The efficacy and safety of STEGLATRO alone and in combination with metformin and/or sitagliptin were evaluated in seven randomized, double-blind, multi-center, controlled Phase 3 clinical trials of adults with inadequately controlled type 2 diabetes.

In six of the trials the primary endpoint was change in HbA1 measured from start of treatment (baseline) up to 26 weeks while maintaining diet and exercise requirement., The seventh trial measured the HbA1c change from baseline up to 52 weeks.

The designs of the seven trials were as follows:

  • Randomized, double-blind, placebo-controlled 26-week trial in patients not on any other drug to treat diabetes (NCT01958671)
  • Randomized, double-blind, placebo-controlled 26-week trial in patients receiving metformin (NCT02033889)
  • Randomized, double-blind, placebo-controlled 26-week trial in patients receiving metformin and sitagliptin (NCT02036515)
  • Randomized, double-blind, placebo-controlled 26-week trial in patients with moderate renal impairment primarily receiving background insulin and/or sulfonylurea therapy (NCT01986855)
  • Randomized double-blind active-controlled 52-week non-inferiority trial comparing STEGLATRO to glimepiride on background metformin (NCT01999218)
  • Randomized, double-blind, active-controlled, 26-week factorial trial in patients receiving background metformin comparing STEGLATRO combined with sitagliptin to sitagliptin alone and to STEGLATRO alone (NCT02099110)
  • Randomized, double-blind, placebo-controlled, 26-weeks trial comparing STEGLATRO combined with sitagliptin in patients not on any other drug to treat diabetes (NCT02226003)

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.
