6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Empagliflozin, Linagliptin and Metformin HCl The safety of concomitantly administered empagliflozin (daily dosage 10 mg or 25 mg), linagliptin (daily dosage 5 mg) and metformin HCl has been evaluated in a total of 686 patients with type 2 diabetes mellitus treated for up to 52 weeks in an active-controlled clinical trial.

The most common adverse reactions are shown in Table 1.

Table 1 Adverse Reactions Reported in ≥5% of Patients Treated with Empagliflozin, Linagliptin, and Metformin HCl in an Active-Controlled Clinical Trial of 52 Weeks Adverse Reactions Empagliflozin 10 mg + Linagliptin 5 mg + Metformin HCl (%) n=136 Empagliflozin 25 mg + Linagliptin 5 mg + Metformin HCl (%) n=137 a Predefined grouping, including, but not limited to, urinary tract infection, asymptomatic bacteriuria, cystitis Upper respiratory tract infection 10.3 8.0 Urinary tract infection a 9.6 10.2 Nasopharyngitis 8.1 5.8 Diarrhea 6.6 2.2 Constipation 5.1 5.8 Headache 5.1 5.1 Gastroenteritis 2.9 5.8 Hypoglycemia The incidence of hypoglycemia (defined as plasma or capillary glucose of less than 54 mg/dL) was 0.7% in patients receiving empagliflozin 10 mg/linagliptin 5 mg/metformin HCl and 0.7% in patients receiving empagliflozin 25 mg/linagliptin 5 mg/metformin HCl.

Events of severe hypoglycemia (requiring assistance regardless of blood glucose) did not occur in this trial.

Empagliflozin Adverse reactions that occurred in ≥2% of patients receiving empagliflozin and more commonly than in patients given placebo included (10 mg, 25 mg, and placebo): urinary tract infection (9.3%, 7.6%, and 7.6%), female genital mycotic infections (5.4%, 6.4%, and 1.5%), upper respiratory tract infection (3.1%, 4.0%, and 3.8%), increased urination (3.4%, 3.2%, and 1.0%), dyslipidemia (3.9%, 2.9%, and 3.4%), arthralgia (2.4%, 2.3%, and 2.2%), male genital mycotic infections (3.1%, 1.6%, and 0.4%), and nausea (2.3%, 1.1%, and 1.4%).

Thirst (including polydipsia) was reported in 0%, 1.7%, and 1.5% for placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively.

Empagliflozin causes an osmotic diuresis, which may lead to intravascular volume contraction and adverse reactions related to volume depletion.

Events related to volume depletion (hypotension and syncope) were reported in 3 patients (1.1%) treated with empagliflozin, linagliptin and metformin HCl combination therapy.

Linagliptin Adverse reactions reported in ≥2% of patients treated with linagliptin 5 mg and more commonly than in patients treated with placebo included: nasopharyngitis (7.0% and 6.1%), diarrhea (3.3% and 3.0%), and cough (2.1% and 1.4%).

Other adverse reactions reported in clinical trials with treatment of linagliptin monotherapy were hypersensitivity (e.g., urticaria, angioedema, localized skin exfoliation, or bronchial hyperreactivity) and myalgia.

In the clinical trial program, pancreatitis was reported in 15.2 cases per 10,000 patient-year exposure while being treated with linagliptin, compared with 3.7 cases per 10,000 patient-year exposure while being treated with comparator (placebo and active comparator, sulfonylurea).

Three additional cases of pancreatitis were reported following the last administered dose of linagliptin.

Metformin HCl The most common (>5%) adverse reactions due to initiation of metformin HCl therapy are diarrhea, nausea/vomiting, flatulence, abdominal discomfort, indigestion, asthenia, and headache.

In a 24-week clinical trial in which extended-release metformin HCl or placebo was added to glyburide therapy, the most common (>5% and greater than placebo) adverse reactions in the combined treatment group were hypoglycemia (13.7% vs 4.9%), diarrhea (12.5% vs 5.6%), and nausea (6.7% vs 4.2%).

Other Adverse Reactions in Clinical Trials with Empagliflozin in Adults Genital Mycotic Infections : In the pool of five placebo-controlled clinical trials, the incidence of genital mycotic infections (e.g., vaginal mycotic infection, vaginal infection, genital infection fungal, vulvovaginal candidiasis, and vulvitis) was increased in patients treated with empagliflozin compared to placebo, occurring in 0.9%, 4.1%, and 3.7% of patients randomized to placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively.

Discontinuation from trial due to genital infection occurred in 0% of placebo-treated patients and 0.2% of patients treated with either empagliflozin 10 mg or 25 mg.

Genital mycotic infections occurred more frequently in female than male patients.

Phimosis occurred more frequently in male patients treated with empagliflozin 10 mg (less than 0.1%) and empagliflozin 25 mg (0.1%) than placebo (0%).

Urinary Tract Infections : In the pool of five placebo-controlled clinical trials, the incidence of urinary tract infections (e.g., urinary tract infection, asymptomatic bacteriuria, and cystitis) was increased in patients treated with empagliflozin compared to placebo.

Patients with a history of chronic or recurrent urinary tract infections were more likely to experience a urinary tract infection.

The rate of treatment discontinuation due to urinary tract infections was 0.1%, 0.2%, and 0.1% for placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively.

Urinary tract infections occurred more frequently in female patients.

The incidence of urinary tract infections in female patients randomized to placebo, empagliflozin 10 mg, and empagliflozin 25 mg was 16.6%, 18.4%, and 17.0%, respectively.

The incidence of urinary tract infections in male patients randomized to placebo, empagliflozin 10 mg, and empagliflozin 25 mg was 3.2%, 3.6%, and 4.1%, respectively [see Use in Specific Populations (8.5) ] .

Lower Limb Amputations : Across four empagliflozin outcome trials, lower limb amputation event rates were 4.3 and 5.0 events per 1,000 patient-years in the placebo group and the empagliflozin 10 mg or 25 mg dose group, respectively, with a HR of 1.05 (95% CI) (0.81, 1.36).

In a long-term cardio-renal outcome trial with empagliflozin, in patients with chronic kidney disease, the occurrence of lower limb amputations was reported with event rates of 2.9, and 4.3 events per 1,000 patient-years in the placebo, and empagliflozin 10 mg treatment arms, respectively.

TRIJARDY XR is not indicated for the treatment of chronic kidney disease.

Laboratory Test Abnormalities in Clinical Trials of Empagliflozin, Linagliptin, or Metformin HCl Empagliflozin Increases in Serum Creatinine and Decreases in eGFR: Initiation of empagliflozin causes an increase in serum creatinine and decrease in eGFR within weeks of starting therapy and then these changes stabilize.

In a trial of patients with moderate renal impairment, larger mean changes were observed.

In a long-term CV outcomes trial, the increase in serum creatinine and decrease in eGFR generally did not exceed 0.1 mg/dL and -9.0 mL/min/1.73 m 2 , respectively, at Week 4, and reversed after treatment discontinuation, suggesting acute hemodynamic changes may play a role in the renal function changes observed with empagliflozin.

Increase in Low-Density Lipoprotein Cholesterol (LDL-C): Dose-related increases in low-density lipoprotein cholesterol (LDL-C) were observed in patients treated with empagliflozin.

LDL-C increased by 2.3%, 4.6%, and 6.5% in patients treated with placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively.

The range of mean baseline LDL-C levels was 90.3 to 90.6 mg/dL across treatment groups.

Increase in Hematocrit: Median hematocrit decreased by 1.3% in placebo and increased by 2.8% in empagliflozin 10 mg and 2.8% in empagliflozin 25 mg-treated patients.

At the end of treatment, 0.6%, 2.7%, and 3.5% of patients with hematocrits initially within the reference range had values above the upper limit of the reference range with placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively.

Linagliptin Increase in Uric Acid: Changes in laboratory values that occurred more frequently in the linagliptin group and ≥1% more than in the placebo group were increases in uric acid (1.3% in the placebo group, 2.7% in the linagliptin group).

Increase in Lipase: In a placebo-controlled clinical trial with linagliptin in type 2 diabetes mellitus patients with micro- or macroalbuminuria, a mean increase of 30% in lipase concentrations from baseline to 24 weeks was observed in the linagliptin arm, compared to a mean decrease of 2% in the placebo arm.

Lipase levels above 3 times upper limit of normal were seen in 8.2% compared to 1.7% patients in the linagliptin and placebo arms, respectively.

Increase in Amylase: In a CV safety trial comparing linagliptin versus glimepiride in patients with type 2 diabetes mellitus, amylase levels above 3 times upper limit of normal were seen in 1.0% compared to 0.5% of patients in the linagliptin and glimepiride arms, respectively.

The clinical significance of elevations in lipase and amylase with linagliptin is unknown in the absence of other signs and symptoms of pancreatitis [see Warnings and Precautions (5.3) ] .

Metformin HCl Decrease in Vitamin B 12 : In metformin HCl clinical trials of 29-week duration, a decrease to subnormal levels of previously normal serum vitamin B 12 levels was observed in approximately 7% of patients.

6.2 Postmarketing Experience Additional adverse reactions have been identified during postapproval use of linagliptin, empagliflozin, or metformin HCl.

Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
