Summary of safety profile
In the completed phase II and phase III registration studies, 4,006 patients were exposed to dulaglutide alone or in combination with other glucose lowering medicinal products. The most frequently reported adverse reactions in clinical trials were gastrointestinal, including nausea, vomiting and diarrhoea. In general these reactions were mild or moderate in severity and transient in nature.
Tabulated list of adverse reactions
The following adverse reactions have been identified based on evaluation of the full duration of the phase II and phase III clinical studies and post-marketing reports and are listed in Table 1 as MedDRA preferred term by system organ class and in order of decreasing incidence (very common: > 1/10; common: > 1/100 to < 1/10; uncommon: > 1/1,000 to < 1/100; rare: > 1/10,000 to < 1/1,000; very rare: < 1/10,000 and not known: cannot be estimated from available data).

Description of selected adverse reactions
Hypoglycaemia
When dulaglutide 0.75 mg and 1.5 mg were used as monotherapy or in combination with metformin alone or metformin and pioglitazone, the incidences of documented symptomatic hypoglycaemia were 5.9% to 10.9% and the rates were 0.14 to 0.62 events/patient/year, and no episodes of severe hypoglycaemia were reported.
The incidences of documented symptomatic hypoglycaemia when dulaglutide 0.75 mg and 1.5 mg, respectively, were used in combination with a sulphonylurea and metformin were 39.0% and 40.3% and the rates were 1.67 and 1.67 events/patient/year. The severe hypoglycaemia event incidences were 0% and 0.7%, and rates were 0.00 and 0.01 events/patient/year for each dose, respectively. The incidence of documented symptomatic hypoglycaemia when dulaglutide 1.5 mg was used with sulphonylurea alone was 11.3% and the rate was 0.90 events/patient/year, and there were no episodes of severe hypoglycaemia.
The incidence of documented symptomatic hypoglycaemia when dulaglutide 1.5 mg was used in combination with insulin glargine was 35.3% and the rate was 3.38 events/patient/year. The severe hypoglycaemia event incidence was 0.7% and the rate was 0.01 events/patient/year.
The incidences when dulaglutide 0.75 mg and 1.5 mg, respectively, were used in combination with prandial insulin were 85.3% and 80.0% and rates were 35.66 and 31.06 events/patient/year. The severe hypoglycaemia event incidences were 2.4% and 3.4%, and rates were 0.05 and 0.06 events/patient/year.
Gastrointestinal adverse reactions
Cumulative reporting of gastrointestinal events up to 104 weeks with dulaglutide 0.75mg and 1.5 mg, respectively, included nausea (12.9% and 21.2 %), diarrhoea (10.7% and 13.7 %) and vomiting (6.9% and 11.5 %). These were typically mild or moderate in severity and were reported to peak during the first 2 weeks of treatment and rapidly declined over the next 4 weeks, after which the rate remained relatively constant.
In clinical pharmacology studies conducted in patients with type 2 diabetes mellitus up to 6 weeks, the majority of gastrointestinal events were reported during the first 2-3 days after the initial dose and declined with subsequent doses.
Acute pancreatitis
The incidence of acute pancreatitis in phase II and III clinical studies was 0.07% for dulaglutide compared to 0.14% for placebo and 0.19% for comparators with or without additional background antidiabetic therapy.
Pancreatic enzymes
Dulaglutide is associated with mean increases from baseline in pancreatic enzymes (lipase and/or pancreatic amylase) of 11 % to 21 %. In the absence of other signs and symptoms of acute pancreatitis, elevations in pancreatic enzymes alone are not predictive of acute pancreatitis.
Heart rate increase
Small mean increases in heart rate of 2 to 4 beats per minute (bpm) and a 1.3% and 1.4 % incidence of sinus tachycardia, with a concomitant increase from baseline > 15 bpm, were observed with dulaglutide 0.75mg and 1.5 mg, respectively.
First degree AV block/PR interval prolongation
Small mean increases from baseline in PR interval of 2 to 3 msec and a 1.5% and 2.4 % incidence of first-degree AV block were observed with dulaglutide 0.75 mg and 1.5 mg, respectively.
Immunogenicity
In clinical studies, treatment with dulaglutide was associated with a 1.6 % incidence of treatment emergent dulaglutide anti-drug antibodies, indicating that the structural modifications in the GLP-1 and modified IgG4 parts of the dulaglutide molecule, together with high homology with native GLP-1 and native IgG4, minimise the risk of immune response against dulaglutide. Patients with dulaglutide anti-drug antibodies generally had low titres, and although the number of patients developing dulaglutide anti-drug antibodies was low, examination of the phase III data revealed no clear impact of dulaglutide anti-drug antibodies on changes in HbA1c. None of the patients with systemic hypersensitivity developed dulaglutide anti-drug antibodies.
Hypersensitivity
In the phase II and phase III clinical studies, systemic hypersensitivity events (e.g., urticaria, oedema) were reported in 0.5 % of patients receiving dulaglutide. Cases of anaphylactic reaction have been rarely reported with marketed use of dulaglutide.
Injection site reactions
Injection site adverse events were reported in 1.9 % of patients receiving dulaglutide. Potentially immune-mediated injection site adverse events (e.g., rash, erythema) were reported in 0.7 % of patients and were usually mild.
Discontinuation due to an adverse event
In studies of 26 weeks duration, the incidence of discontinuation due to adverse events was 2.6% (0.75 mg) and 6.1% (1.5 mg) for dulaglutide versus 3.7 % for placebo. Through the full study duration (up to 104 weeks), the incidence of discontinuation due to adverse events was 5.1% (0.75 mg) and 8.4 % (1.5 mg) for dulaglutide. The most frequent adverse reactions leading to discontinuation for 0.75 mg and 1.5 mg dulaglutide, respectively, were nausea (1.0%, 1.9 %), diarrhoea (0.5%, 0.6 %), and vomiting (0.4%, 0.6 %), and were generally reported within the first 4-6 weeks.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Ireland: HPRA Pharmacovigilance, Earlsfort Terrace, IRL - Dublin 2, Tel: +353 1 6764971, Fax: +353 1 6762517; website: www.hpra.ie; e-mail: [email protected], or United Kingdom: Yellow Card Scheme; website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Non-clinical data reveal no special hazards for humans based on conventional studies of safety pharmacology or repeat-dose toxicity.
In a 6-month carcinogenicity study in transgenic mice, there was no tumorigenic response. In a 2-year carcinogenicity study in rats, at > 7 times the human clinical exposure following 1.5 mg dulaglutide per week, dulaglutide caused statistically significant, dose-related increases in the incidence of thyroid C-cell tumours (adenomas and carcinomas combined). The clinical relevance of these findings is currently unknown.
During the fertility studies, a reduction in the number of corpora lutea and prolonged oestrous cycle were observed at dose levels that were associated with decreased food intake and body weight gain in maternal animals; however, no effects on indices of fertility and conception or embryonic development were observed. In reproductive toxicology studies, skeletal effects and a reduction in foetal growth were observed in the rat and rabbit at exposures of dulaglutide 11- to 44-fold higher than those proposed clinically, but no foetal malformations were observed. Treatment of rats throughout pregnancy and lactation produced memory deficits in female offspring at exposures that were 16-fold higher than those proposed clinically. Dulaglutide dosing of male and female juvenile rats did not produce memory deficits at 91-fold the human exposure.
Trulicity is indicated in adults with type 2 diabetes mellitus to improve glycaemic control as:
Monotherapy
When diet and exercise alone do not provide adequate glycaemic control in patients for whom the use of metformin is considered inappropriate due to intolerance or contraindications.
Add-on therapy
Pharmacotherapeutic group: Drugs used in diabetes, blood glucose lowering drugs, excl. insulins, glucagon-like peptide-1 (GLP-1) analogues ATC code: A10BJ05.
Mechanism of action
Dulaglutide is a long-acting glucagon-like peptide 1 (GLP-1) receptor agonist. The molecule consists of 2 identical disulfide-linked chains, each containing a modified human GLP-1 analogue sequence covalently linked to a modified human immunoglobulin G4 (IgG4) heavy chain fragment (Fc) by a small peptide linker. The GLP-1 analog portion of dulaglutide is approximately 90 % homologous to native human GLP-1 (7-37). Native GLP-1 has a half-life of 1.5-2 minutes due to degradation by DPP-4 and renal clearance. In contrast to native GLP-1, dulaglutide is resistant to degradation by DPP-4, and has a large size that slows absorption and reduces renal clearance. These engineering features result in a soluble formulation and a prolonged half-life of 4.7 days, which makes it suitable for once-weekly subcutaneous administration. In addition, the dulaglutide molecule was engineered to prevent the Fcγ receptor-dependent immune response and to reduce its immunogenic potential.
Dulaglutide exhibits several antihyperglycaemic actions of GLP-1. In the presence of elevated glucose concentrations, dulaglutide increases intracellular cyclic AMP (cAMP) in pancreatic beta cells leading to insulin release. Dulaglutide suppresses glucagon secretion which is known to be inappropriately elevated in patients with type 2 diabetes. Lower glucagon concentrations lead to decreased hepatic glucose output. Dulaglutide also slows gastric emptying.
Pharmacodynamic effects
Dulaglutide improves glycaemic control through the sustained effects of lowering fasting, pre-meal and postprandial glucose concentrations in patients with type 2 diabetes starting after the first dulaglutide administration and is sustained throughout the once weekly dosing interval.
A pharmacodynamic study with dulaglutide demonstrated, in patients with type 2 diabetes, a restoration of first phase insulin secretion to a level that exceeded levels observed in healthy subjects on placebo, and improved second phase insulin secretion in response to an intravenous bolus of glucose. In the same study, a single 1.5 mg dose of dulaglutide appeared to increase maximal insulin secretion from the β-cells, and to enhance β-cell function in subjects with type 2 diabetes mellitus as compared with placebo.
Consistent with the pharmacokinetic profile, dulaglutide has a pharmacodynamic profile suitable for once weekly administration.
Clinical efficacy and safety
Glycaemic control
The safety and efficacy of dulaglutide were evaluated in eight randomised, controlled, phase III trials involving 5,770 patients with type 2 diabetes. Of these, 1,139 were > 65 years of which 115 were > 75 years. These studies included 3,525 dulaglutide-treated patients, of whom 2,108 were treated with Trulicity 1.5 mg weekly and 1,417 were treated with Trulicity 0.75 mg weekly. In all studies, dulaglutide produced clinically significant improvements in glycaemic control as measured by glycosylated haemoglobin A1c (HbA1c).
Monotherapy
Dulaglutide was studied in a 52 week active controlled monotherapy study in comparison to metformin. Trulicity 1.5 mg and 0.75 mg were superior to metformin (1500-2000 mg/day) in the reduction in HbA1c and a significantly greater proportion of patients reached an HbA1c target of < 7.0 % and ≤ 6.5 % with Trulicity 1.5 mg and Trulicity 0.75 mg compared to metformin at 26 weeks.

Combination therapy with metformin
The safety and efficacy of dulaglutide was investigated in a placebo and active controlled (sitagliptin 100 mg daily) study of 104 weeks duration, all in combination with metformin. Treatment with Trulicity 1.5 mg and 0.75 mg resulted in a superior reduction in HbA1c compared to sitagliptin at 52 weeks, accompanied by a significantly greater proportion of patients achieving HbA1c targets of < 7.0 % and ≤ 6.5 %. These effects were sustained to the end of the study (104 weeks).

Combination therapy with metformin and sulphonylurea
In an active controlled study of 78 weeks duration, dulaglutide was compared to insulin glargine, both on a background of metformin and a sulphonylurea. At 52 weeks, Trulicity 1.5 mg demonstrated superior lowering in HbA1c to insulin glargine which was maintained at 78 weeks; whereas lowering in HbA1c with Trulicity 0.75 mg was non-inferior to insulin glargine. With Trulicity 1.5 mg a significantly higher percentage of patients reached a target HbA1c of < 7.0 % or ≤ 6.5 % at 52 and 78 weeks compared to insulin glargine.

The rates of documented symptomatic hypoglycaemia with Trulicity 0.75 mg, Trulicity 1.5 mg, and placebo were 0.15, 0.16 and 0.12 episodes/patient/year, respectively. One patient reported severe hypoglycaemia with Trulicity 0.75 mg in combination with SGLT2i therapy and none with Trulicity 1.5 mg or placebo.
Combination therapy with metformin and pioglitazone
In a placebo and active (exenatide twice daily) controlled study, both in combination with metformin and pioglitazone, Trulicity 1.5 mg and 0.75 mg demonstrated superiority for HbA1c reduction in comparison to placebo and exenatide, accompanied by a significantly greater percentage of patients achieving HbA1c targets of < 7.0 % or ≤ 6.5 %.

Absorption
Following subcutaneous administration to patients with type 2 diabetes, dulaglutide reaches peak plasma concentrations in 48 hours. The mean peak (Cmax) and total (AUC) exposures were approximately 114 ng/ml and 14,000 ngh/ml, respectively, after multiple subcutaneous 1.5 mg doses of dulaglutide in patients with type 2 diabetes. Steady-state plasma concentrations were achieved between 2 to 4 weeks of once-weekly administration of dulaglutide (1.5 mg). Exposures after subcutaneous administration of single dulaglutide (1.5 mg) doses in the abdomen, thigh, or upper arm were comparable. The mean absolute bioavailability of dulaglutide following single-dose subcutaneous administration of single 1.5 mg and 0.75 mg doses was 47 % and 65%, respectively.
Distribution
The mean volume of distribution after subcutaneous administration of dulaglutide 0.75 mg and 1.5 mg at steady state in patients with type 2 diabetes mellitus were approximately 19.2 L and 17.4 L.
Biotransformation
Dulaglutide is presumed to be degraded into its component amino acids by general protein catabolism pathways.
Elimination
The mean apparent clearance of dulaglutide 0.75 mg and 1.5 mg at steady state was 0.111 L/h and 0.107 L/h with an elimination half-life of 4.5 and 4.7 days, respectively.
Special populations
Elderly
Age had no clinically relevant effect on the pharmacokinetic and pharmacodynamic properties of dulaglutide.
Gender and race
Gender and race had no clinically meaningful effect on the pharmacokinetics of dulaglutide.
Body weight or body mass index
Pharmacokinetic analyses have demonstrated a statistically significant inverse relationship between body weight or body mass index (BMI) and dulaglutide exposure, although there was no clinically relevant impact of weight or BMI on glycaemic control.
Renal impairment
The pharmacokinetics of dulaglutide were evaluated in a clinical pharmacology study and were generally similar between healthy subjects and patients with mild to severe renal impairment (CrCl < 30 mL/min), including end stage renal disease (requiring dialysis). Additionally, in a 52-week clinical study in patients with type 2 diabetes and moderate to severe renal impairment (eGFR [by CKD-EPI] < 60 and > 15 mL/min/1.73 m2), the pharmacokinetic profile of Trulicity 0.75 mg and 1.5 mg once weekly was similar to that demonstrated in previous clinical studies. This clinical study did not include patients with end stage renal disease.
Hepatic impairment
The pharmacokinetics of dulaglutide were evaluated in a clinical pharmacology study, where subjects with hepatic impairment had statistically significant decreases in dulaglutide exposure of up to 30 % to 33 % for mean Cmax and AUC, respectively, compared to healthy controls. There was a general increase in tmax of dulaglutide with increased hepatic impairment. However, no trend in dulaglutide exposure was observed relative to the degree of hepatic impairment. These effects were not considered to be clinically relevant.
Paediatric population
Studies characterising the pharmacokinetics of dulaglutide in paediatric patients have not been performed.

Pregnancy
There are no or limited amount of data from the use of dulaglutide in pregnant women. Studies in animals have shown reproductive toxicity. Therefore, the use of dulaglutide is not recommended during pregnancy.
Breast-feeding
It is unknown whether dulaglutide is excreted in human milk. A risk to newborns/infants cannot be excluded. Dulaglutide should not be used during breast-feeding.
Fertility
The effect of dulaglutide on fertility in humans is unknown. In the rat, there was no direct effect on mating or fertility following treatment with dulaglutide.
Dulaglutide should not be used in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis.
Use of GLP-1 receptor agonists may be associated with gastrointestinal adverse reactions. This should be considered when treating patients with impaired renal function since these events, i.e. nausea, vomiting, and/or diarrhoea, may cause dehydration which could cause a deterioration of renal function. Dulaglutide has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is therefore not recommended in these patients.
Acute pancreatitis
Use of GLP-1 receptor agonists has been associated with a risk of developing acute pancreatitis. In clinical trials, acute pancreatitis has been reported in association with dulaglutide.
Patients should be informed of the characteristic symptoms of acute pancreatitis. If pancreatitis is suspected, dulaglutide should be discontinued. If pancreatitis is confirmed, dulaglutide should not be restarted. In the absence of other signs and symptoms of acute pancreatitis, elevations in pancreatic enzymes alone are not predictive of acute pancreatitis.
Hypoglycaemia
Patients receiving dulaglutide in combination with sulphonylurea or insulin may have an increased risk of hypoglycaemia. The risk of hypoglycaemia may be lowered by a reduction in the dose of sulphonylurea or insulin.
Populations not studied
There is limited experience in patients with congestive heart failure.
Sodium content
This medicinal product contains less than 1 mmol sodium (23 mg) per 1.5 mg dose, i.e. essentially 'sodium- free'.
Trulicity has no or negligible influence on the ability to drive or use machines. When it is used in combination with a sulphonylurea or insulin, patients should be advised to take precautions to avoid hypoglycaemia while driving and using machines.
Posology
Monotherapy
The recommended dose is 0.75 mg once weekly.
Add-on therapy
The recommended dose is 1.5 mg once weekly.
For potentially vulnerable populations, such as patients > 75 years, 0.75 mg once weekly can be considered as a starting dose.
When Trulicity is added to existing metformin and/or pioglitazone therapy, the current dose of metformin and/or pioglitazone can be continued. When Trulicity is added to existing metformin and/or sodium-glucose co-transporter 2 inhibitor (SGLT2i) therapy, the current dose of metformin and/or SGLT2i can be continued. When it is added to existing therapy of a sulphonylurea or insulin, a reduction in the dose of sulphonylurea or insulin may be considered to reduce the risk of hypoglycaemia.
The use of Trulicity does not require blood glucose self-monitoring. Self-monitoring may be necessary to adjust the dose of sulphonylurea or insulin.
Elderly
No dose adjustment is required based on age. However, the therapeutic experience in patients > 75 years is very limited , and in these patients 0.75 mg once weekly can be considered as a starting dose.
Renal impairment
No dosage adjustment is required in patients with mild, moderate or severe renal impairment (eGFR < 90 to > 15 mL/min/1.73 m2).
There is very limited experience in patients with end stage renal disease (< 15 mL/min/1.73 m2), therefore Trulicity cannot be recommended in this population.
Hepatic impairment
No dosage adjustment is required in patients with hepatic impairment.
Paediatric population
The safety and efficacy of dulaglutide in children aged less than 18 years have not yet been established. No data are available.
Method of administration
Trulicity is to be injected subcutaneously in the abdomen, thigh or upper arm. It should not be administered intravenously or intramuscularly.
The dose can be administered at any time of day, with or without meals.
If a dose is missed, it should be administered as soon as possible if there are at least 3 days (72 hours) until the next scheduled dose. If less than 3 days (72 hours) remain before the next scheduled dose, the missed dose should be skipped and the next dose should be administered 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 (72 hours) before.
Any unused medicinal product or waste material should be disposed of in accordance with local requirements.

Date of first authorisation: 21 November 2014
Dulaglutide delays gastric emptying and has the potential to impact the rate of absorption of concomitantly administered oral medicinal products. Dulaglutide should be used with caution in patients receiving oral medicinal products that require rapid gastrointestinal absorption. For some prolonged release formulations, an increased release due to an extended gastric residence time may slightly increase drug exposure.
Paracetamol
Following a first dose of 1 and 3 mg dulaglutide, paracetamol Cmax was reduced by 36 % and 50 %, respectively, and the median tmax occurred later (3 and 4 hours, respectively). After coadministration with up to 3 mg of dulaglutide at steady state, there were no statistically significant differences on AUC(0-12), Cmax or tmax of paracetamol. No dose adjustment of paracetamol is necessary when administered with dulaglutide.
Atorvastatin
Coadministration of dulaglutide with atorvastatin decreased Cmax and AUC(0-∞) up to 70 % and 21 %, respectively, for atorvastatin and its major metabolite o-hydroxyatorvastatin. The mean t1/2 of atorvastatin and o-hydroxyatorvastatin were increased by 17 % and 41 %, respectively, following dulaglutide administration. These observations are not clinically relevant. No dose adjustment of atorvastatin is necessary when administered with dulaglutide.
Digoxin
After coadministration of steady state digoxin with 2 consecutive doses of dulaglutide, overall exposure (AUC) and tmax of digoxin were unchanged; and Cmax decreased by up to 22 %. This change is not expected to have clinical consequences. No dose adjustment is required for digoxin when administered with dulaglutide.
Anti-hypertensives
Coadministration of multiple dulaglutide doses with steady state lisinopril caused no clinically relevant changes in the AUC or Cmax of lisinopril. Statistically significant delays in lisinopril tmax of approximately 1 hour were observed on Days 3 and 24 of the study. When a single dose of dulaglutide and metoprolol were coadministered, the AUC and Cmax of metoprolol increased by19 % and 32 %, respectively. While metoprolol tmax was delayed by 1 hour, this change was not statistically significant. These changes were not clinically relevant; therefore no dose adjustment of lisinopril or metoprolol is necessary when administered with dulaglutide.
Warfarin
Following dulaglutide coadministration, S- and R-warfarin exposure and R-warfarin Cmax were unaffected, and S-warfarin Cmax decreased by 22 %. AUCINR increased by 2 %, which is unlikely to be clinically significant, and there was no effect on maximum international normalised ratio response (INRmax). The time of international normalised ratio response (tINRmax) was delayed by 6 hours, consistent with delays in tmax of approximately 4 and 6 hours for S- and R-warfarin, respectively. These changes are not clinically relevant. No dose adjustment for warfarin is necessary when given together with dulaglutide.
Oral contraceptives
Coadministration of dulaglutide with an oral contraceptive (norgestimate 0.18 mg/ethinyl estradiol 0.025 mg) did not affect the overall exposure to norelgestromin and ethinyl estradiol. Statistically significant reductions in Cmax of 26 % and 13 % and delays in tmax of 2 and 0.30 hours were observed for norelgestromin and ethinyl estradiol, respectively. These observations are not clinically relevant. No dose adjustment for oral contraceptives is required when given together with dulaglutide.
Metformin
Following coadministration of multiple dose dulaglutide with steady state metformin (immediate release formula [IR]), metformin AUC increased up to 15 % and Cmax decreased up to 12 %, respectively, with no changes in tmax. These changes are consistent with the gastric emptying delay of dulaglutide and within the pharmacokinetic variability of metformin and thus are not clinically relevant. No dose adjustment for metformin IR is recommended when given with dulaglutide.
Sitagliptin
Sitagliptin exposure was unaffected when coadministered with a single dose of dulaglutide. Following coadministration with 2 consecutive doses of dulaglutide, sitagliptin AUC(0-) and Cmax decreased by approximately 7.4 % and 23.1 %, respectively. Sitagliptin tmax increased approximately 0.5 hours following coadministration with dulaglutide compared to sitagliptin alone.
Sitagliptin can produce up to 80 % inhibition of DPP-4 over a 24-hour period. Dulaglutide coadministration with sitagliptin increased dulaglutide exposure and Cmax by approximately 38 % and 27 %, respectively, and median tmax increased approximately 24 hours. Therefore, dulaglutide does have a high degree of protection against DPP-4 inactivation. The increased exposure may enhance the effects of dulaglutide on blood glucose levels.
