LAPS CA -Exendin-4 (efpeglenatide) Enhances Insulin Secretion and Beta Cell Responsiveness in Subjects with Type 2 Diabetes Background and Aims LAPS Exendin-4 (HM11260C) is a glucagon like peptide -1 (GLP-1) receptor agonist being developed for the treatment of type 2 diabetes mellitus (T2DM). In this phase 1B study the effects of different HM11260C regimens on insulin secretion rate (ISR), β-cell responsiveness, and gastric emptying (GE) compared to placebo and to liraglutide were investigated. Materials and Methods Subjects with T2DM received 6 mg HM11260C weekly (cohort A; age: 52.8 years, HbA1c: 8.4, n=13), 16 mg HM11260C monthly (cohort B; age: 50.1 yr, HbA1c: 8.1, n=13), 1.8 mg liraglutide daily (cohort C; age: 54.9 yr, HbA1c: 8.02 n=13), or placebo (age: 54.1 yr, HbA1c: 8.6, n=8). Subjects in cohorts A and C were evaluated at baseline and steady state, and cohort B was evaluated at trough (day[d]82) and peak(d89) drug concentration. Islet β-cell function was assessed during a graded IV glucose infusion (GGI); infusion steps: 2, 4, 6, 8, 12 mg/kg/min of 20% IV glucose for 30 min each. Insulin C-peptide levels, and plasma glucose response to each GGI step were measured. ISR were determined using a population based C-peptide de-convolution model. AUC(insulin) and AUC(C-peptide) as measures of ISR were determined for each treatment. β-cell responsiveness was assessed as the ratio of ISR/ blood glucose (BG) over the duration of the GGI, and the slope of the ISR/BG was compared between the treatments. The rate of GE was determined for 1g of liquid acetaminophen following a mixed meal and a mixed meal tolerance test (MMTT) was performed. For GE, non-inferiority to liraglutide was tested using a margin of 0.8 for the least squares (LS) mean ratio. Results Insulin secretion for all active treatments was increased compared to placebo and for HM11260C 6 mg and 16 mg was greater than for liraglutide (point estimates LS mean ratio: 1.765 mU/L, 90% CI: 1.331, 2.342 mU/L, one-sided p=0.0008, and LS mean ratio: 1.440 mU/L, 90% CI: 1.080, 1.920 mU/L, one-sided p=0.0196). Comparisons of the relationship between ISR and plasma glucose using mixed effects modelling showed an improvement in beta cell responsiveness relative to placebo/baseline which was not different among treatments. In the monthly treatment group, there was a diminution of effect at PK trough (d82). For postprandial glucose following the MMTT the LS means of the Cmax, AUC0-180, and AUC0-360 parameters were significantly (two- sided p < 0.05) reduced in subjects who received either 6 mg HM11260C or 16 mg HM11260C when compared to placebo. Cohort A demonstrated less inhibition of GE and was non-inferior (lower CI limit >0.8) to liraglutide in terms of acetaminophen Cmax, AUC0-120minand AUC0- 180min. While for Cohort B the effect on gastric emptying appeared to be similar or even less when compared to liraglutide, formal non-inferiority could not be established for all parameters. GE was delayed in cohorts A and B compared to placebo.

Background and aims: HM11260C (HM) is a novel long acting GLP-1R

agonist with a T1/2 of ~ 158 hrs resulting in a flat PK profile. This 12-week,

randomized, placebo (PBO) controlled, double-blind parallel group study

with an open label active control liraglutide (LIRA) arm, was designed to

investigate the dose ranging efficacy, safety, and tolerability of once weekly

(QW) doses of HM in subjects with Type 2 Diabetes (T2DM).

Materials and methods: Stratified by metformin use 254 patients (mean

age 55.3 yrs, BMI 31.76 kg/m2, diabetes duration 73.08 months) were

randomized to one of five HM QW doses, PBO or to LIRA QD up-titrated to

1.8 mg. All HM doses were not titrated.

Results: HM 0.3 to 4 mg produced dose-dependent reduction in HbA1c,

fasting plasma glucose, and 7-point daily glucose. In addition, HM 4 mg

reached statistical significance in demonstration for non-inferiority to LIRA

by mean % change of HbA1c from baseline (Difference= -0.23, 95.1% CI=[-

0.56, 0.10]). Attainment of target HbA1c ≤ 7% with HM was 83.3% (3 mg,

p<0.0001) and 80.6% (4 mg, p<0.0001) vs 30.3% (PBO), and 61.1% (LIRA).

The reduction in body weight with HM 3 mg (2.732 kg) and 4 mg (3.309 kg)

was significantly greater than that with PBO (1.290 kg, p<0.049, both). The

most frequent AEs were gastrointestinal side effects of mild or moderate

severity: nausea and vomit that subsided over time.

Conclusion: In summary, all doses of HM demonstrated clinically

meaningful improvements in blood glucose and body weight, with higher

doses being more effective. Safety profiles were comparable to LIRA. The

current results warrant further studies to assess the long-term efficacy and

safety of HM11260C in T2DM.

ABSTRACT

• Overview of HM11260C (Efpeglenatide)

A modified Exendin4 (CA-EXD4) has been

conjugated to a human IgG4 Fc using a PEG

linker which leads to slow elimination, thereby

resulting in a decreased dosing schedule.

• Study Objectives

a. Primary objective

- To assess and compare the efficacy of five doses of HM11260C

(once weekly subcutaneous injections) over the 12 weeks from

baseline in comparison with placebo (once weekly subcutaneous

injections) on glycaemic control, as assessed by HbA1c in

subjects with T2DM

b. Secondary objectives

- To assess the effect on safety, tolerability, immunogenicity,

diabetes-related parameters (FPG and 7-point glucose profile)

and body weight change.

- To explore the relationship between PK and PD measurements

Significant Effects of HM11260C (efpeglenatide) on Body Weight over 20 weeks in Obese Subjects without Diabetes: a Randomized, Double-blind, Placebo Controlled study

ABSTRACT Background and aims: HM11260C (HM) is a novel long acting GLP-1R

agonist with a T1/2 of ~ 158 hrs resulting in a flat PK profile. This 20-week,

randomized, double-blind, placebo (PBO) controlled, parallel group study

was designed to evaluate the efficacy, safety, and tolerability of once a

week (QW) or every other week (Q2W) doses of HM in obese subjects

without diabetes.

Materials and methods: 297 subjects (mean age 43.4 yrs and BMI 35.5

kg/m2) were randomized to one of four HM doses (4 mg QW, 6 mg QW, 6

mg Q2W, or 8 mg Q2W) or to PBO. HM was administered subcutaneously

for 20 weeks. The diet and exercise regimens remained unchanged during

the study.

Results: The body weight loss with HM 4mg QW, 6 mg QW, 6 mg Q2W

and 8 mg Q2W was 6.2 kg, 7.8 kg, 7.0 kg and 7.1 kg (LS Mean, p<0.0001

all HM treatment groups), whereas body weight gain was observed with

PBO (0.8 kg). More subjects in the HM treatment groups achieved

significant body weight loss ≥5% or ≥10%, and the mean reductions in BMI

from baseline were greater, compared with PBO. Changes from baseline in

waist circumference were -6.00 cm, -9.45 cm, -7.11 cm, -8.00 cm and -

0.21 cm (LS Mean) with HM 4mg QW, 6 mg QW, 6 mg Q2W, 8 mg Q2W

and PBO. The most frequent adverse events were gastrointestinal events

which were observed relatively frequently and increased injection site

reactions which were less common.

Conclusion: All doses of HM meaningfully reduced body weight and were

well tolerated. These results warrant further studies to assess titration

schemes as well as the long-term efficacy and safety of HM in obesity.

CONCLUSION

• All doses of efpeglenatide meaningfully reduced body weight and

exceeded regulatory requirements for anti-obesity drugs. These

results warrant further studies to assess titration schemes as well as

the long-term efficacy and safety of efpeglenatide in obese

population.

• The abstract included the results of an interim analysis available at the

time of submission. Since then, the final analysis has been completed

and is reported in the poster.

• Obesity is highly associated with a majority of metabolic diseases (WHO

Obesity and Overweight Fact sheet; updated March 2013).

• Few effective drugs are currently available for the treatment of obesity;

better therapeutic options that are safe and well tolerated and that can

lower the risks associated with obesity are needed.

• 8 weeks of treatment with HM11260C (LAPSCA-Exendin-4, efpeglenatide),

a GLP-1 agonist, resulted in marked weight loss compared with placebo

(Kang et al., 2013). The purpose of this study is to determine the optimal

dose and regimen of efpeglenatide, when administered subcutaneously

weekly or biweekly to reduce weight in obese subjects without diabetes.

• Primary objective

To assess the effect of efpeglenatide on body weight over the 20 weeks

from baseline in obese subjects

• Secondary objectives

To assess the safety, tolerability, and immunogenicity of efpeglenatide

over the 20 weeks from baseline in obese subjects

• Statistically significant body weight reduction was observed over 20

weeks with once a week (QW) and every other week (Q2W)

treatment of efpeglenatide in all groups.

• Statistically significant increases in heart rate were observed, however,

they were within the expected range for GLP-1 receptor agonists.

Blood pressure decreased within the expected range for GLP-1

receptor agonists, but was only significant at the 6 mg QW dose.

• Most of nausea and vomiting occurred with the first few injections and

subsided over the time.

• Overall treatment emergent anti-efpeglenatide antibodies were

detected in 20.0% (47 out of 235 efpeglenatide-treated subjects).

None of patients with positive drug antibodies showed neutralizing

antibody against efpeglenatide.

Superagonistic mechanism of increased glucodynamic and weight loss effects of LAPSCA-Exendin-4 (efpeglenatide)

IY Choi1, SH Park1, M Trautmann2, SY Hwang1, JY Kim1, SM Bae1, YM Lee1, JH Kang1, SC Kwon1 1Hanmi Pharm. Co., Ltd, Seoul, South Korea, 2Profil Institute, Chula Vista, CA, USA

RESULTS

• Following conjugation to Fc the fast receptor dissociation kinetics of

CA-Exendin-4 were maintained in efpeglenatide. (kd 4.2x10-3s-1 vs.

1.0x10-3 s-1 for efpeglenatide).

• Efpeglenatide lead to significantly less GLP-1R internalization than

liraglutide and dulaglutide in human GLP-1R transformed cells. This

translated into more potent glucose lowering in db/db mice and

greater body weight loss in DIO mice in comparison to liraglutide

and dulaglutide.

• Efpeglenatide maintained potent glucose lowering efficacy in db/db

mice even at conditions mimicking human dosing.

• CA-Exendin-4 even after conjugation to the human Fc-fragment

seems to achieve more pronounced GLP-1R activation due to

reduced receptor internalization and consequently leads to more

potent effects. These findings may explain the observed efficacy of

efpeglenatide in clinical trials relative to liraglutide.

Less GLP-1R desensitization by efpeglenatide

METHODS • The receptor kinetics were measured by a SPR (Surface Plasmon Resonance) assay using immobilized extracellular domain of the human GLP-1 receptor which is fused to the GST (glutathione S transferase).

• Intracellular cyclic AMP and insulin released to the assay medium were measured, following 1hr treatment with GLP-1RAs in a rat insulinoma cell, RINm5F or GLP-1R overexpressing CHO cells.

• Acute glucose lowering efficacy was investigated by intraperitonial glucose tolerance test following a single dose of various concentrations of exendin-4 analogs in normal C57BL/6 mice.

• Internalization of GLP-1 receptor was assessed in hGLP-1R/U2OS cells using the PathHunter™ eXpress Kit (DiscoveRx Corporation. Ltd., UK). Surface GLP-1 receptors were measured in hGLP-1R/CHO cells after pretreatment with 10 nM or 100 nM GLP-1RAs at 37°C for 5 min to 60 min. The remaining surface receptors were detected by binding of 100 pM125I-GLP-1 at 4°C for 4 h.

• In vitro activity after chronic treatment of GLP-1RAs was determined by measuring intracellular cyclic AMP in GLP-1R/CHO and insulin release in RINm5F cells. The cells were pre-treated with 10 nM of GLP-1RAs for 4 to 24 hours and followed by cAMP or insulinotropic induction by re-challenge with 0-5,000 nM of GLP-1RAs.

• In vivo efficacy between efpeglenatide and other GLP-1RAs was compared by subcutaneous administration in human PK fluctuation mimic condition, Change of blood glucose was monitored during 4 weeks and HbA1c was determined at the end point in db/db mice. Efficacy in body weight lowering and food intake inhibition was compared in DIO mice for 4 weeks.
