Limitations of Use

TRULICITY:

• Has not been studied in patients with a history of pancreatitis [see Warnings and Precautions (5.2)]. Consider other antidiabetic therapies in patients with a history of pancreatitis.
• Should not be used in patients with type 1 diabetes mellitus.
• Has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis and is therefore not recommended in these patients [see Warnings and Precautions (5.6)].

2.1 Adult Dosage

• The recommended starting dosage of TRULICITY is 0.75 mg injected subcutaneously once weekly.
• Increase the dosage to 1.5 mg once weekly for additional glycemic control.
• If additional glycemic control is needed, increase the dosage in 1.5 mg increments after at least 4 weeks on the current dosage.
• The maximum recommended dosage is 4.5 mg injected subcutaneously once weekly.

2.2 Pediatric Dosage

• The recommended starting dosage of TRULICITY is 0.75 mg injected subcutaneously once weekly.
• If additional glycemic control is needed, increase the dosage to the maximum recommended dosage of 1.5 mg once weekly after at least 4 weeks on the 0.75 mg dosage.

2.3 Recommendations Regarding Missed Dose

• If a dose is missed, instruct patients to administer the dose as soon as possible if there are at least 3 days (72 hours) until the next scheduled dose. If less than 3 days remain before the next scheduled dose, skip the missed dose and administer the next dose on the regularly scheduled day. In each case, patients can then resume their regular once weekly dosing schedule.
• The day of weekly administration can be changed, if necessary, as long as the last dose was administered 3 or more days before the new day of administration.

2.4 Important Administration Instructions

• Prior to initiation, train patients and caregivers on proper injection technique [see Instructions for Use].
• Administer TRULICITY once weekly, any time of day, with or without food.
• Inject TRULICITY subcutaneously in the abdomen, thigh, or upper arm.
• Rotate injection sites with each dose.
• Inspect TRULICITY visually before use. It should appear clear and colorless. Do not use TRULICITY if particulate matter or coloration is seen.
• When using TRULICITY with insulin, administer as separate injections and never mix. It is acceptable to inject TRULICITY and insulin in the same body region, but the injections should not be adjacent to each other.

5.1 Risk of Thyroid C-cell Tumors

In male and female rats, dulaglutide causes a dose-related and treatment-duration-dependent increase in the incidence of thyroid C-cell tumors (adenomas and carcinomas) after lifetime exposure [see Nonclinical Toxicology (13.1)]. Glucagon-like peptide-1 (GLP-1) receptor agonists have induced thyroid C-cell adenomas and carcinomas in mice and rats at clinically relevant exposures. It is unknown whether TRULICITY will cause thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of dulaglutide-induced rodent thyroid C-cell tumors has not been determined.

One case of MTC was reported in a patient treated with TRULICITY in a clinical trial. This patient had pretreatment calcitonin levels approximately 8 times the upper limit of normal (ULN). An additional case of C-cell hyperplasia with elevated calcitonin levels following treatment was reported in the cardiovascular outcomes trial (REWIND). Cases of MTC in patients treated with liraglutide, another GLP-1 receptor agonist, have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and GLP-1 receptor agonist use in humans.

TRULICITY is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2. Counsel patients regarding the potential risk for MTC with the use of TRULICITY and inform them of symptoms of thyroid tumors (e.g. a mass in the neck, dysphagia, dyspnea, persistent hoarseness).

Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with TRULICITY. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin values may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.

5.2 Pancreatitis

In a pooled analysis from the original registration studies, 12 (3.4 cases per 1000 patient years) pancreatitis-related adverse reactions were reported in patients exposed to TRULICITY versus 3 in non-incretin comparators (2.7 cases per 1000 patient years). An analysis of adjudicated events revealed 5 cases of confirmed pancreatitis in patients exposed to TRULICITY (1.4 cases per 1000 patient years) versus 1 case in non-incretin comparators (0.88 cases per 1000 patient years).

Based on an analysis of adjudicated events in a clinical trial evaluating Trulicity 1.5 mg, 3 mg, or 4.5 mg once weekly, pancreatitis occurred in 1 patient exposed to TRULICITY 1.5 mg (0.2%), in 2 patients exposed to TRULICITY 3 mg (0.3%), and 3 patients exposed to TRULICITY 4.5 mg (0.5%).

After initiation of TRULICITY, observe patients carefully for signs and symptoms of pancreatitis, including persistent severe abdominal pain, sometimes radiating to the back, which may or may not be accompanied by vomiting. If pancreatitis is suspected, promptly discontinue TRULICITY and initiate appropriate management. If pancreatitis is confirmed, TRULICITY should not be restarted. TRULICITY has not been evaluated in patients with a prior history of pancreatitis. Consider other antidiabetic therapies in patients with a history of pancreatitis.

5.3 Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin

Patients receiving TRULICITY in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia [see Adverse Reactions (6.1) and Drug Interactions (7)].

The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.

5.4 Hypersensitivity Reactions

There have been postmarketing reports of serious hypersensitivity reactions including anaphylactic reactions and angioedema in patients treated with TRULICITY [see Adverse Reactions (6.2)]. If a hypersensitivity reaction occurs, discontinue TRULICITY; treat promptly per standard of care, and monitor until signs and symptoms resolve. TRULICITY is contraindicated in patients with a previous serious hypersensitivity reaction to dulaglutide or to any of the components of TRULICITY.

Anaphylaxis and angioedema have been reported with other GLP-1 receptor agonists. Use caution in a patient with a history of angioedema or anaphylaxis with another GLP-1 receptor agonist because it is unknown whether such patients will be predisposed to anaphylaxis with TRULICITY.

5.5 Acute Kidney Injury

In patients treated with GLP-1 receptor agonists, including TRULICITY, there have been postmarketing reports of acute renal failure and worsening of chronic renal failure, which may sometimes require hemodialysis. Some of these events were reported in patients without known underlying renal disease. A majority of reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. Because these reactions may worsen renal function, use caution when initiating or escalating doses of TRULICITY in patients with renal impairment. Monitor renal function in patients with renal impairment reporting severe adverse gastrointestinal reactions [see Use in Specific Populations (8.6)].

5.6 Severe Gastrointestinal Disease

Use of TRULICITY may be associated with gastrointestinal adverse reactions, sometimes severe [see Adverse Reactions (6.1)]. TRULICITY has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is therefore not recommended in these patients.

5.7 Diabetic Retinopathy Complications in Patients with a History of Diabetic Retinopathy

In a cardiovascular outcomes trial with a median follow up of 5.4 years involving patients with type 2 diabetes with established cardiovascular disease or multiple cardiovascular risk factors, diabetic retinopathy complications occurred in patients treated with TRULICITY 1.5 mg (1.9%) and placebo (1.5%). These events were prospectively ascertained as a secondary composite endpoint. The proportion of patients with diabetic retinopathy complications was larger among patients with a history of diabetic retinopathy at baseline (TRULICITY 8.5%, placebo 6.2%) than among patients without a known history of diabetic retinopathy (TRULICITY 1%, placebo 1%).

Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. Patients with a history of diabetic retinopathy should be monitored for progression of diabetic retinopathy.

5.8 Acute Gallbladder Disease

Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In a cardiovascular outcomes trial with a median follow up of 5.4 years, cholelithiasis occurred at a rate of 0.62/100 patient-years in TRULICITY-treated patients and 0.56/100 patient-years in placebo-treated patients after adjusting for prior cholecystectomy. Serious events of acute cholecystitis were reported in 0.5% and 0.3% of patients on TRULICITY and placebo respectively. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated.

6.1 Clinical Trials Experience

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

6.2 Postmarketing Experience

The following additional adverse reactions have been reported during post-approval use of TRULICITY. Because these events 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.

• Gastrointestinal: ileus
• Hepatobiliary: cholecystitis, cholelithiasis requiring cholecystectomy, cholestasis, elevation of liver enzymes, hepatitis
• Hypersensitivity: anaphylactic reactions, angioedema
• Renal: acute renal failure or worsening of chronic renal failure, sometimes requiring hemodialysis

7.1 Oral Medications

TRULICITY delays gastric emptying and thus has the potential to reduce the rate of absorption of concomitantly administered oral medications. The delay in gastric emptying is dose-dependent but is attenuated with the recommended dose escalation to higher doses of TRULICITY [see Dosage and Administration (2.1)]. The delay is largest after the first dose and diminishes with subsequent doses. In clinical pharmacology studies, TRULICITY 1.5 mg did not affect the absorption of the tested orally administered medications to a clinically relevant degree [see Clinical Pharmacology (12.3)]. There is limited experience with the use of concomitant medications in clinical trials with TRULICITY doses of 3 mg and 4.5 mg.

Monitor drug levels of oral medications with a narrow therapeutic index (e.g., warfarin) when concomitantly administered with TRULICITY.

7.2 Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with Insulin

When initiating TRULICITY, consider reducing the dose of concomitantly administered insulin secretagogues (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions (5.3) and Adverse Reactions (6.1)].

8.1 Pregnancy

8.2 Lactation

8.4 Pediatric Use

The safety and effectiveness of TRULICITY as an adjunct to diet and exercise to improve glycemic control in pediatric patients 10 years of age and older with type 2 diabetes mellitus have been established. Use of TRULICITY for this indication is supported by a 26-week, multicenter, randomized, double-blind, parallel arm, placebo-controlled trial in 154 pediatric patients 10 years of age and older with type 2 diabetes mellitus [see Clinical Studies (14.6)].

TRULICITY-treated pediatric patients reported a higher incidence of injection site-related reactions compared to TRULICITY-treated adults [see Adverse Reactions (6.1)].

The safety and effectiveness of TRULICITY have not been established in pediatric patients less than 10 years of age.

8.5 Geriatric Use

In the adult glycemic control trials [see Clinical Studies (14.2, 14.3)], 620 (19%) of TRULICITY-treated patients were 65 years of age or older and 65 (2%) of TRULICITY-treated patients were 75 years of age or older at baseline. In the TRULICITY 1.5 mg treatment arm of the REWIND trial (cardiovascular outcomes trial in adults with type 2 diabetes mellitus and cardiovascular disease or multiple cardiovascular risk factors) [see Clinical Studies (14.5)], 2,619 (53%) patients were 65 years of age or older, and 484 (10%) patients were 75 years of age or older at baseline.

No overall differences in safety or effectiveness for TRULICITY have been observed between patients 65 years of age and older and younger adult patients.

8.6 Renal Impairment

TRULICITY has been studied in patients with varying degrees of renal function, including a dedicated clinical trial in patients with moderate to severe chronic kidney disease. No overall differences in safety or effectiveness were observed in these studies according to renal function [see Clinical Studies (14.2, 14.3, 14.4)].

In a clinical pharmacology study in patients with renal impairment, including end-stage renal disease (ESRD), no clinically relevant change in dulaglutide pharmacokinetics (PK) was observed. In the 52-week trial in patients with type 2 diabetes and moderate to severe renal impairment, the PK behavior of TRULICITY 0.75 mg and 1.5 mg once weekly was similar to that demonstrated in previous clinical studies [see Clinical Pharmacology (12.3)].

No dose adjustment is recommended in patients with renal impairment including end-stage renal disease (ESRD). Monitor renal function in patients with renal impairment reporting severe adverse gastrointestinal reactions. Use TRULICITY with caution in patients with ESRD [see Warning and Precautions (5.5), Clinical Pharmacology (12.3)].

8.7 Hepatic Impairment

In a clinical pharmacology study in patients with varying degrees of hepatic impairment, no clinically relevant change in dulaglutide PK was observed [see Clinical Pharmacology (12.3)]. However, there is limited clinical experience in patients with mild, moderate, or severe hepatic impairment; therefore, use TRULICITY with caution in these patient populations.

8.8 Gastroparesis

Dulaglutide slows gastric emptying. TRULICITY has not been studied in patients with preexisting gastroparesis. Use TRULICITY with caution in patients with gastroparesis.

12.1 Mechanism of Action

TRULICITY contains dulaglutide, which is a human GLP-1 receptor agonist with 90% amino acid sequence homology to endogenous human GLP-1 (7-37). Dulaglutide activates the GLP-1 receptor, a membrane-bound cell-surface receptor coupled to adenylyl cyclase in pancreatic beta cells. Dulaglutide increases intracellular cyclic AMP (cAMP) in beta cells leading to glucose-dependent insulin release. Dulaglutide also decreases glucagon secretion and slows gastric emptying.

12.2 Pharmacodynamics

TRULICITY lowers fasting glucose and reduces postprandial glucose (PPG) concentrations in patients with type 2 diabetes mellitus. The reduction in fasting and postprandial glucose can be observed after a single dose.

12.3 Pharmacokinetics

The pharmacokinetics of dulaglutide is similar between healthy subjects and patients with type 2 diabetes mellitus. Following subcutaneous administration, the time to maximum plasma concentration of dulaglutide at steady state ranges from 24 to 72 hours, with a median of 48 hours. After reaching steady state, the accumulation ratio was approximately 1.56. Steady-state plasma dulaglutide concentrations were achieved between 2 and 4 weeks following once weekly administration. Site of subcutaneous administration (abdomen, upper arm, and thigh) had no statistically significant effect on the exposure to dulaglutide.

Absorption – The mean absolute bioavailability of dulaglutide following subcutaneous administration of single 0.75 mg and 1.5 mg doses was 65% and 47%, respectively. Absolute subcutaneous bioavailability for 3 mg and 4.5 mg doses were estimated to be similar to 1.5 mg although this has not been specifically studied. Dulaglutide concentrations increased approximately proportional to dose from 0.75 mg to 4.5 mg.

Distribution – Apparent population mean central volume of distribution was 3.09 L and the apparent population mean peripheral volume of distribution was 5.98 L.

Elimination

The apparent population mean clearance of dulaglutide was 0.142 L/h. The elimination half-life of dulaglutide was approximately 5 days.

Metabolism – Dulaglutide is presumed to be degraded into its component amino acids by general protein catabolism pathways.

Specific Populations

The intrinsic factors of age (≥ 65 years), sex, race, ethnicity, body weight, or renal or hepatic impairment did not have a clinically relevant effect on the PK of dulaglutide as shown in Figure 1.

Abbreviations: AUC = area under the time-concentration curve; CI = confidence interval; Cmax = maximum concentration; ESRD = end-stage renal disease; PK = pharmacokinetics.

Note: Reference values for weight, age, gender, and race comparisons are 93 kg, 56 years old, male, and white, respectively; reference groups for renal and hepatic impairment data are subjects with normal renal and hepatic function from the respective clinical pharmacology studies. The weight values shown in the plot (70 and 120 kg) are the 10th and 90th percentiles of weight in the PK population.

Figure 1: Impact of intrinsic factors on dulaglutide pharmacokinetics.

Drug Interaction Studies

The potential effect of co-administered medications on the PK of dulaglutide 1.5 mg and vice versa was studied in several single- and multiple-dose studies in healthy subjects, patients with type 2 diabetes mellitus, and patients with hypertension.

Potential for Dulaglutide to Influence the Pharmacokinetics of Other Drugs

Dulaglutide slows gastric emptying and, as a result, may reduce the extent and rate of absorption of orally co-administered medications. In clinical pharmacology studies, dulaglutide at a dose of 1.5 mg did not affect the absorption of the tested orally administered medications to any clinically relevant degree. The delay in gastric emptying is dose-dependent but is attenuated with the recommended dose escalation to higher doses of TRULICITY [see Dosage and Administration (2.1), Drug Interactions (7.1)]. The delay is largest after the first dose and diminishes with subsequent doses. PK measures indicating the magnitude of these interactions are presented in Figure 2.

Abbreviations: AUC = area under the time-concentration curve; CI = confidence interval; Cmax = maximum concentration; PK = pharmacokinetics.

Note: Reference group is co-administered medication given alone.

12.6 Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies.

In glycemic control trials in adults with type 2 diabetes mellitus (monotherapy and combination therapy) [see Clinical Studies (14.2, 14.3)], during a treatment period ranging from 24 to 104 weeks, 64/3,907 (1.6%) of TRULICITY-treated patients developed anti-dulaglutide antibodies (referred to as anti-drug-antibodies (ADA)). Of the 64 TRULICITY-treated patients that developed ADA, 34 patients (0.9% of the overall population) developed dulaglutide-neutralizing antibodies, and 36 patients (0.9% of the overall population) developed antibodies against native GLP-1. There was no identified clinically significant effect of ADA on pharmacokinetics, pharmacodynamics, safety, or effectiveness of TRULICITY over the 24 to 104 week treatment duration in the trials in adults with type 2 diabetes mellitus.

During the 26-week controlled period of the glycemic control trial in pediatric patients 10 years of age or older with type 2 diabetes mellitus [see Clinical Studies (14.6)], 4/101 (4%) of TRULICITY-treated pediatric patients developed ADA. Of the 4 pediatric patients that developed ADA, 1 patient (1% of the overall population) developed dulaglutide-neutralizing antibodies and 3 patients (3% of the overall population) developed antibodies against native GLP-1. During the 52-week postbaseline period of the same trial (through safety follow-up), 6/103 (6%) of TRULICITY-treated patients developed ADA. Of the 6 patients that developed ADA, 1 patient (1% of the overall population) developed dulaglutide-neutralizing antibodies and 4 patients (4% of the overall population) developed antibodies against native GLP-1. Because of the low occurrence of ADA, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of TRULICITY is unknown in pediatric patients.

13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility

A 2-year carcinogenicity study was conducted with dulaglutide in male and female rats at doses of 0.05, 0.5, 1.5, and 5 mg/kg (0.2-, 3-, 8-, and 24-fold the MRHD of 4.5 mg once weekly based on AUC) administered by subcutaneous injection twice weekly. In rats, dulaglutide caused a dose-related and treatment-duration-dependent increase in the incidence of thyroid C-cell tumors (adenomas and/or carcinomas) compared to controls, at ≥3-fold the MRHD based on AUC. A statistically significant increase in C-cell adenomas was observed in rats receiving dulaglutide at ≥0.5 mg/kg. Numerical increases in thyroid C-cell carcinomas occurred at 5 mg/kg (24 times the MRHD based on AUC) and were considered to be treatment-related despite the absence of statistical significance.

A 6-month carcinogenicity study was conducted with dulaglutide in rasH2 transgenic mice at doses of 0.3, 1, and 3 mg/kg administered by subcutaneous injection twice weekly. Dulaglutide did not produce increased incidences of thyroid C-cell hyperplasia or neoplasia at any dose.

Dulaglutide is a recombinant protein; no genotoxicity studies have been conducted.

Human relevance of thyroid C-cell tumors in rats is unknown and could not be determined by clinical studies or nonclinical studies [see Boxed Warning and Warnings and Precautions (5.1)].

In fertility and early embryonic development studies in male and female rats, no adverse effects of dulaglutide on sperm morphology, mating, fertility, conception, and embryonic survival were observed at up to 16.3 mg/kg (55-fold the MRHD based on AUC). In female rats, an increase in the number of females with prolonged diestrus and a dose-related decrease in the mean number of corpora lutea, implantation sites, and viable embryos were observed at ≥4.9 mg/kg (≥13-fold the MRHD based on AUC), which occurred in the presence of decreased maternal food consumption and body weight gain.

13.2 Animal Toxicology and/or Pharmacology

Zucker diabetic fatty (ZDF) rats were given 0.5, 1.5, or 5 mg/kg/twice weekly of dulaglutide (1-, 3-, and 13-fold the MRHD based on AUC) for 3 months. Increases of 12% to 33% in total and pancreatic amylase, but not lipase, were observed at all doses without microscopic pancreatic inflammatory correlates in individual animals. Other changes in the dulaglutide-treated animals included increased interlobular ductal epithelium without active ductal cell proliferation (≥0.5 mg/kg), increased acinar atrophy with/without inflammation (≥1.5 mg/kg), and increased neutrophilic inflammation of the acinar pancreas (5 mg/kg).

Treatment of monkeys for 12 months with 8.15 mg/kg/twice weekly of dulaglutide (nearly 200-fold the MRHD based on AUC) demonstrated no evidence of pancreatic inflammation or pancreatic intraepithelial neoplasia. In 4 of 19 monkeys on dulaglutide treatment, there was an increase in goblet cells within the pancreatic ducts, but no differences from the control group in total amylase or lipase at study termination. There were no proliferative changes in the thyroid C-cells.

14.1 Overview of Clinical Trials

TRULICITY has been studied in adults as monotherapy and in combination with metformin, sulfonylurea, metformin and sulfonylurea, metformin and thiazolidinedione, sodium-glucose co-transporter-2 inhibitors (SGLT2i) with or without metformin, basal insulin with or without metformin, and prandial insulin with or without metformin. TRULICITY has also been studied in patients with type 2 diabetes mellitus and moderate to severe renal impairment.

Dose escalation was performed in one trial in adults with TRULICITY doses up to 4.5 mg added to metformin. All other clinical studies in adults evaluated TRULICITY 0.75 mg and 1.5 mg without dose escalation; patients were initiated and maintained on either 0.75 mg or 1.5 mg for the duration of the trials [see Clinical Studies (14.2, 14.3, 14.4)].

TRULICITY 0.75 mg and 1.5 mg was studied in pediatric patients 10 years of age and older with type 2 diabetes in combination with or without metformin and/or basal insulin treatment [see Clinical Studies (14.6)].

In patients with type 2 diabetes mellitus, TRULICITY produced reductions from baseline in HbA1c compared to placebo. No overall differences in glycemic effectiveness were observed across demographic subgroups (age, gender, race/ethnicity, duration of diabetes).

A cardiovascular outcomes trial was conducted in adult patients with type 2 diabetes mellitus and established cardiovascular (CV) disease or multiple cardiovascular risk factors. Patients were randomized to TRULICITY 1.5 mg or placebo both added to standard of care. TRULICITY significantly reduced the risk of first occurrence of primary composite endpoint of CV death, non-fatal MI, or non-fatal stroke [see Clinical Studies (14.5)].

14.2 Glycemic Control Monotherapy Trials in Adults with Type 2 Diabetes Mellitus

In a double-blind trial with primary endpoint at 26 weeks, 807 adult patients inadequately treated with diet and exercise, or with diet and exercise and one antidiabetic agent used at submaximal dose, were randomized to TRULICITY 0.75 mg once weekly, TRULICITY 1.5 mg once weekly, or metformin 1500 to 2000 mg/day following a two-week washout. Seventy-five percent (75%) of the randomized population were treated with one antidiabetic agent at the screening visit. Most patients previously treated with an antidiabetic agent were receiving metformin (~90%) at a median dose of 1000 mg daily and approximately 10% were receiving a sulfonylurea.

Patients had a mean age of 56 years and a mean duration of type 2 diabetes of 3 years. Forty-four percent were male. The White, Black and Asian race accounted for 74%, 7% and 8% of the population, respectively. Twenty-nine percent of the trial population were from the US.

Treatment with TRULICITY 0.75 mg and 1.5 mg once weekly resulted in reduction in HbA1c from baseline at 26-weeks (Table 4). The difference in observed effect size between TRULICITY 0.75 mg and 1.5 mg, respectively, and metformin excluded the pre-specified non-inferiority margin of 0.4%.

14.3 Glycemic Control Combination Therapy Trials in Adults with Type 2 Diabetes Mellitus

Sitagliptin-Controlled Trial (Add-on to Metformin)

In this placebo-controlled, double-blind trial with primary endpoint at 52 weeks, 972 adult patients were randomized to placebo, TRULICITY 0.75 mg once weekly, TRULICITY 1.5 mg once weekly, or sitagliptin 100 mg/day (after 26 weeks, patients in the placebo treatment group received blinded sitagliptin 100 mg/day for the remainder of the trial), all as add-on to metformin. Randomization occurred after an 11-week lead-in period to allow for a metformin titration period, followed by a 6-week glycemic stabilization period. Patients had a mean age of 54 years; mean duration of type 2 diabetes of 7 years; 48% were male; race: White, Black and Asian were 53%, 4% and 27%, respectively; and 24% of the trial population were in the US.

At the 26-week placebo-controlled time point, the HbA1c change was 0.1%, -1.0%, -1.2%, and -0.6% for placebo, TRULICITY 0.75 mg, TRULICITY 1.5 mg, and sitagliptin, respectively. The percentage of patients who achieved HbA1c <7.0% was 22%, 56%, 62% and 39% for placebo, TRULICITY 0.75 mg, TRULICITY 1.5 mg, and sitagliptin, respectively. At 26 weeks, there was a mean weight reduction of 1.4 kg, 2.7 kg, 3.0 kg, and 1.4 kg for placebo, TRULICITY 0.75 mg, TRULICITY 1.5 mg, and sitagliptin, respectively. There was a mean reduction of fasting glucose of 9 mg/dL, 35 mg/dL, 41 mg/dL, and 18 mg/dL for placebo, TRULICITY 0.75 mg, TRULICITY 1.5 mg, and sitagliptin, respectively.

Treatment with TRULICITY 0.75 mg and 1.5 mg once weekly resulted in a statistically significant reduction in HbA1c compared to placebo (at 26 weeks) and compared to sitagliptin (at 26 and 52 weeks), all in combination with metformin (Table 5 and Figure 3).

Dosage Ranging Trial of TRULICITY 1.5, 3 mg, and 4.5 mg (Add-on to Metformin)

In this parallel-arm, double-blind trial with primary endpoint at 36 weeks, a total of 1842 adult patients were randomized 1:1:1 to TRULICITY 1.5 mg, TRULICITY 3 mg, or TRULICITY 4.5 mg once weekly, all as add-on to metformin (NCT03495102).

Following randomization, all patients received TRULICITY 0.75 mg once weekly. The dose was increased every 4 weeks to the next higher dose until the patients reached their assigned dose (1.5 mg, 3 mg, or 4.5 mg). Patients were to remain on the assigned study dose for the duration of the trial.

Patients had a mean age of 57.1 years; a mean duration of type 2 diabetes of 7.6 years; 51.2% were male; race: White, Black, and Asian were 85.8%, 4.5%, and 2.4%, respectively; and 27.6% of the trial population was in the US.

At 36 weeks, treatment with TRULICITY 4.5 mg resulted in a statistically significant reduction in HbA1c and in body weight compared to TRULICITY 1.5 mg (Table 6 and Figure 4).

Placebo- and Exenatide-Controlled Trial (Add-on to Metformin and Thiazolidinedione)

In this placebo-controlled trial with primary endpoint at 26 weeks, 976 adult patients were randomized to and received placebo, TRULICITY 0.75 mg once weekly, TRULICITY 1.5 mg once weekly, or exenatide 10 mcg BID, all as add-on to maximally tolerated doses of metformin (≥1500 mg per day) and pioglitazone (up to 45 mg per day). Exenatide treatment group assignment was open-label while the treatment assignments to placebo, TRULICITY 0.75 mg, and TRULICITY 1.5 mg were blinded. After 26 weeks, patients in the placebo treatment group were randomized to either TRULICITY 0.75 mg once weekly or TRULICITY 1.5 mg once weekly to maintain blinding. Randomization occurred after a 12-week lead-in period; during the initial 4 weeks of the lead-in period, patients were titrated to maximally tolerated doses of metformin and pioglitazone; this was followed by an 8-week glycemic stabilization period prior to randomization. Patients randomized to exenatide started at a dose of 5 mcg BID for 4 weeks and then were escalated to 10 mcg BID. Patients had a mean age of 56 years; mean duration of type 2 diabetes of 9 years; 58% were male; race: White, Black and Asian were 74%, 8% and 3%, respectively; and 81% of the trial population were in the US.

Treatment with TRULICITY 0.75 mg and 1.5 mg once weekly resulted in a statistically significant reduction in HbA1c compared to placebo (at 26 weeks) and compared to exenatide at 26 weeks (Table 8 and Figure 5). Over the 52-week trial period, the percentage of patients who required glycemic rescue was 8.9% in the TRULICITY 0.75 mg once weekly + metformin and pioglitazone treatment group, 3.2% in the TRULICITY 1.5 mg once weekly + metformin and pioglitazone treatment group, and 8.7% in the exenatide BID + metformin and pioglitazone treatment group.

14.4 Glycemic Control Trials in Adults with Type 2 Diabetes Mellitus and Moderate to Severe Chronic Kidney Disease

In this open-label comparator trial (double-blind with respect to TRULICITY dose assignment) with primary endpoint at 26 weeks, a total of 576 adult patients with type 2 diabetes were randomized and treated to compare TRULICITY 0.75 mg and 1.5 mg with insulin glargine (NCT01621178).

Patients on insulin and other antidiabetic therapy (e.g., oral antidiabetic drugs, pramlintide) had non-insulin therapies discontinued and had their insulin dose adjusted for 12 weeks prior to randomization. Patients on insulin therapy alone maintained a stable insulin dose for 3 weeks prior to randomization. At randomization, patients discontinued their pre-trial insulin regimen and patients were randomized to TRULICITY 0.75 mg once weekly, TRULICITY 1.5 mg once weekly, or insulin glargine once daily, all in combination with prandial insulin lispro. For patients randomized to insulin glargine, the initial insulin glargine dose was based on the basal insulin dose prior to randomization. Insulin glargine was allowed to be titrated with a fasting plasma glucose goal of ≤150 mg/dL. Insulin lispro was allowed to be titrated with a preprandial and bedtime glucose goal of ≤180 mg/dL.

Patients had a mean age of 65 years; a mean duration of type 2 diabetes of 18 years; 52% were male; race: White, Black, and Asian were 69%, 16%, and 3%, respectively; and 32% of the trial population were in the US. At baseline, overall mean eGFR was 38 mL/min/1.73 m2, 30% of patients had eGFR <30 mL/min/1.73 m2, and 45% of patients had macroalbuminuria. Patients on over 70 units/day of basal insulin were excluded from the trial.

Treatment with TRULICITY 0.75 mg and 1.5 mg once weekly resulted in a reduction in HbA1c at 26-weeks from baseline. The difference in observed effect size between TRULICITY 0.75 mg and 1.5 mg, respectively, and glargine in this trial excluded the pre-specified non-inferiority margin of 0.4%. Mean fasting plasma glucose increased in the TRULICITY arms (Table 13).

Mean baseline body weight was 90.9 kg, 88.1 kg, and 88.2 kg in the TRULICITY 0.75 mg, TRULICITY 1.5 mg, and insulin glargine arms, respectively. The mean changes from baseline at Week 26 were -1.1, -2, and 1.9 kg in the TRULICITY 0.75 mg, TRULICITY 1.5 mg, and insulin glargine arms, respectively.

14.5 Cardiovascular Outcomes Trial in Adults with Type 2 Diabetes Mellitus and Cardiovascular Disease or Multiple Cardiovascular Risk Factors

The REWIND trial (NCT01394952) was a multi-national, multi-center, randomized, placebo-controlled, double-blind trial. In this trial, 9901 adult patients with type 2 diabetes mellitus and established cardiovascular (CV) disease or multiple cardiovascular risk factors were randomized to TRULICITY 1.5 mg or placebo both added to standard of care. The median follow-up duration was 5.4 years. The primary endpoint was the time to the first occurrence of a composite 3-component Major Adverse Cardiovascular Events (MACE) outcome, which included CV death, non-fatal myocardial infarction (MI), and non-fatal stroke.

Patients eligible to enter the trial were 50 years of age or older who had type 2 diabetes mellitus, had an HbA1c value ≤9.5% with no lower limit at screening, and had either established CV disease, or did not have established CV disease but had multiple CV risk factors. Patients who were confirmed to have established CV disease (31.5% of randomized patients) had a history of at least one of the following: MI (16.2%); myocardial ischemia by a stress test or with cardiac imaging (9.3%); ischemic stroke (5.3%); coronary, carotid, or peripheral artery revascularization (18.0%); unstable angina (5.9%); or hospitalization for unstable angina with at least one of the following: ECG changes, myocardial ischemia on imaging, or a need for percutaneous coronary intervention (12.0%). Patients confirmed to be without established CV disease, but with multiple CV risk factors, comprised 62.8% of the randomized trial population.

At baseline, demographic and disease characteristics were balanced between treatment groups. Patients had a mean age of 66 years; 46% were female; race: White, Black, and Asian were 76%, 7%, and 4%, respectively.

The median baseline HbA1c was 7.2%. The mean duration of type 2 diabetes was 10.5 years and the mean BMI was 32.3 kg/m2.

At baseline, 50.5% of patients had mild renal impairment (eGFR ≥60 but <90 mL/min/1.73m2), 21.6% had moderate renal impairment (eGFR ≥30 but <60 mL/min/1.73m2), and 1.1% of patients had severe renal impairment (eGFR <30 mL/min/1.73m2) out of 9713 patients whose eGFR were available.

At baseline, 94.7% of patients were taking antidiabetic medication, with 10.5% of patients taking three or more antidiabetic drugs. The most common background antidiabetic drugs used at baseline were metformin (81.2%), sulfonylurea (46.0%), and insulin (23.9%). At baseline, CV disease and risk factors were managed with ACE inhibitors or angiotensin receptor blockers (81.5%), beta blockers (45.6%), calcium channel blockers (34.4%), diuretics (46.5%), statin therapy (66.1%), antithrombotic agents (58.7%), and aspirin (51.7%). During the trial, investigators were to modify anti-diabetic and cardiovascular medications to achieve local standard of care treatment targets with respect to blood glucose, lipids, and blood pressure, and manage patients recovering from an acute coronary syndrome or stroke event per local treatment guidelines.

For the primary analysis, a Cox proportional hazards model was used to test for superiority. Type I error was controlled across multiple tests. TRULICITY significantly reduced the risk of first occurrence of primary composite endpoint of CV death, non-fatal MI, or non-fatal stroke (HR: 0.88, 95% CI 0.79, 0.99). Refer to Figure 6 and Table 14.

Vital status was available for 99.7% of patients in the trial. A total of 1128 deaths were recorded during the REWIND trial. A majority of the deaths in the trial were adjudicated as CV deaths, and non-CV deaths were comparable between the treatment groups (4.4% in patients treated with TRULICITY and 5.0% in patients treated with placebo). There were 536 all-cause deaths (10.8%) in the dulaglutide group compared to 592 deaths (12.0%) in the placebo group.

14.6 Glycemic Control Trial in Pediatric Patients 10 Years of Age and Older with Type 2 Diabetes Mellitus

In this 26-week randomized, double-blind, placebo-controlled, parallel-arm, multicenter trial with an open-label extension for an additional 26 weeks,154 pediatric patients 10 years of age and older with type 2 diabetes mellitus, who had inadequate glycemic control despite diet and exercise, were randomized to subcutaneous TRULICITY once weekly (0.75 mg and 1.5 mg) or subcutaneous placebo once weekly in combination with or without metformin and/or basal insulin treatment (NCT02963766).

Overall, in this trial demographic and baseline disease characteristics were comparable across the treatment groups. At baseline, 71% of patients were female, and the mean age was 14.5 years (ranging from 10 to 17 years). Overall, 55% were White, 15% were Black or African American, 12% were Asian, 10% were American Indian or Alaska Native, 5% were other races, and 3% had unknown race. Additionally, 55% were Hispanic or Latino, 42% were not Hispanic or Latino, and 3% had unknown ethnicity. At baseline, the mean duration of type 2 diabetes mellitus was 2 years, mean HbA1c was 8.1%, mean weight was 90.5 kg and mean BMI was 34.1 kg/m2.

In this trial, once weekly TRULICITY (0.75 mg and 1.5 mg, pooled) (with or without metformin and/or basal insulin) was superior to placebo (p<0.001) in the change from baseline at Week 26 in HbA1c in pediatric patients 10 years of age and older with type 2 diabetes mellitus (see Table 15).
