TRULICITY Dulaglutide .75 mg/.5mL Injection, Solution, 4 syringes — NDC 50090-6453-0 (Billing 50090-6453-00)

12 CLINICAL PHARMACOLOGY

12.1Mechanism 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.

12.2Pharmacodynamics 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. Fasting and Postprandial Glucose In a clinical pharmacology study in patients with type 2 diabetes mellitus, treatment with once weekly TRULICITY resulted in a reduction of fasting and 2-hour PPG concentrations, and postprandial serum glucose incremental AUC, when compared to placebo (-25.6 mg/dL, -59.5 mg/dL, and -197 mg*h/dL, respectively); these effects were sustained after 6 weeks of dosing with the 1.5 mg dose.

First- and Second-Phase Insulin Secretion Both first- and second-phase insulin secretion were increased in patients with type 2 diabetes treated with TRULICITY compared with placebo. Insulin and Glucagon Secretion TRULICITY stimulates glucose-dependent insulin secretion and reduces glucagon secretion. Treatment with TRULICITY 0.75 mg and 1.5 mg once weekly increased fasting insulin from baseline at Week 26 by 35.38 and 17.50 pmol/L, respectively, and C-peptide concentration by 0.09 and 0.07 nmol/L, respectively, in a monotherapy trial.

In the same trial, fasting glucagon concentration was reduced by 1.71 and 2.05 pmol/L from baseline with TRULICITY 0.75 mg and 1.5 mg, respectively. Gastric Motility Dulaglutide causes a delay of gastric emptying. The delay in gastric emptying is dose-dependent but is attenuated with adequate dose escalation to higher doses of TRULICITY.

The delay is largest after the first dose and diminishes with subsequent doses. Cardiac Electrophysiology (QTc) The effect of dulaglutide on cardiac repolarization was tested in a thorough QTc study. Dulaglutide did not produce QTc prolongation at doses of 4 and 7 mg.

The maximum recommended dose is 4.5 mg once weekly.

12.3Pharmacokinetics 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

5.98L. 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… [Excerpted — this section continues on DailyMed.]

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; C max = 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 10 th and 90 th percentiles of weight in the PK population. Figure 1: Impact of intrinsic factors on dulaglutide pharmacokinetics.

Figure 1 Pediatric Patients A population pharmacokinetic analysis was conducted for dulaglutide 0.75 mg and 1.5 mg using data from 128 pediatric patients 10 years of age and older with type 2 diabetes mellitus. The AUC in pediatric patients was approximately 37% lower than that in adult patients. However, this difference was not determined to be clinically meaningful.

Patients with Renal Impairment Dulaglutide systemic exposure was increased by 20, 28, 14 and 12% for mild, moderate, severe, and ESRD renal impairment sub-groups, respectively, compared to subjects with normal renal function. The corresponding values for increase in C max were 13, 23, 20 and 11%, respectively ( Figure 1 ). Additionally, in a 52 week clinical trial in patients with type 2 diabetes mellitus 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 Warning and Precautions ( 5.5 ), Use in Specific Populations ( 8.6 )] .

Patients with Hepatic Impairment Dulaglutide systemic exposure decreased by 23, 33 and 21% for mild, moderate and severe hepatic impairment groups, respectively, compared to subjects with normal hepatic function, and C max was decreased by a similar magnitude ( Figure 1 ) [see Use in Specific Populations ( 8.7 )] . 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.

14 CLINICAL STUDIES

14.1Overview 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 )] .

14.2Glycemic 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%.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, 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.

13.2Animal 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.
