Table 1. Baseline Characteristics
• HM12525A is a novel ultra-long-acting
dual agonist which consists of a
chemically synthesized GLP-1/GCG
peptide, conjugated with a human IgG
Fc fragment via a flexible PEG linker
• HM12525A exhibits a well balanced
agonism at the GLP-1 receptor and
the glucagon receptor (1:1 ratio)
Overview of HM12525A
Study Objectives
• Primary objective
- To evaluate safety and tolerability of HM12525A in healthy
volunteers after single administration of HM12525A
• Secondary objectives

Figure 3. 24hr ambulatory monitoring: systolic/diastolic
blood pressure and heart rate at peak PK concentration
• The confirmed long half life after a single dose supports the
potential use of HM12525A for weekly or longer injection intervals.
• Heart rate elevation was observed with increasing dose levels,
while no clinically relevant changes in BPs during 24hr ABP
monitoring at peak concentration were observed.
• As expected, GI disorders—known to be related to the mode of
action of GLP-1 and GCG—were the major AEs, and no clinically
meaningful changes in laboratory parameters were observed.
• Low incidence of treatment emergent antibodies and no
neutralizing antibodies were observed.
• Further clinical trials will investigate the efficacy and the safety in
the disease population.

Day -1 Day 4/5*
Day -1 Day 4/5* Background and aims Glucagon-like peptide-1 (GLP-1)
/glucagon (GCG) dual agonists may have potential to treat
obesity and diabetes by activating both GLP-1 and GCG
receptors. The once-weekly LAPSGLP/GCG dual agonist,
HM12525A, is site-specifically conjugated by LAPSCOVERY
technology for sustained duration of activity. By combining the
synergetic GLP-1/GCG effects with this long-acting platform,
HM12525A may improve patient compliance and thereby
treatment outcomes further. This First-in-Human, Phase I,
randomized, double-blind, placebo-controlled single
ascending dose study evaluated the safety, tolerability, PK
and PD of HM12525A in healthy volunteers.
Materials and methods Forty subjects (age: 48.3±10.4
years; male: 70%; BMI: 29.7±3.3kg/m2) were randomly
assigned to 5 cohorts (0.25, 0.5, 1.0, 2.0, and 4.0 nmol/kg),
and received a single subcutaneous injection of either
HM12525A or placebo (ratio, 3:1). The total duration of the
study was 56 days, including follow up.
Results HM12525A demonstrated prolonged PK profiles.
The observed Cmax in each cohort ranged from 0.759 to 18.5
nmol/L at 113.1±55.3 hr post-dose. AUC0-last (120 to 6560
hr·nmol/L) and T1/2 (112.5 to 276.2 hr) was also observed.
Among the 5 cohorts, the maximum tolerated single dose was
determined at a dose level of 2.0 nmol/kg. Overall, none of
the subjects exhibited any clinically significant alterations in
vital signs, laboratory values, and 24hr ambulatory ECG.
During 24hr ambulatory blood pressure (24hr ABP)
assessments, no significant change in heart rate (HR) was
observed up to 1.0 nmol/kg dose. At 2.0 and 4.0 nmol/kg
doses, mean HR was elevated by 5.77±2.30 and 8.06±2.56
(p-value: 0.017 and 0.004) compared to placebo, while mean
systolic and diastolic BPs showed no significant changes.
Anti-drug antibodies were detected in 7 subjects; 3 subjects
already had ADA at baseline, while the other 4 were newly
detected during the study. None of these 7 subjects had
neutralizing antibodies. The most frequent treatment
emergent adverse events (TEAEs) were gastrointestinal
disorders, such as nausea and vomiting. No serious TEAEs
were occurred.
Conclusion In summary, this single ascending dose study
demonstrated that HM12525A had a prolonged PK profile and
was well tolerated, confirming the potential for once-weekly
injections. Further investigation in T2DM patients will explore
the synergistic potential of this LAPSGLP/GCG dual agonist to
provide for a beneficial and effective therapeutic regimen.

AIMS
Dual agonists activating the GLP-1 receptor (GLP-1R) and the glucagon receptor (GCG-R) may represent a new therapeutic approach for obesity with the potential for enhanced weight loss beyond those of GLP-1R agonists. Oxyntomodulin, a human gut hormone with agonism to the GLP-1R and the GCG-R, causes a significant reduction in weight by regulating both, appetite and energy expenditure, however its clinical application is limited due to a short half-life. HM12525A is a long-acting GLP-1/glucagon receptor dual agonist for once-weekly administration. It consists of a GLP-1/ glucagon receptor dual agonist conjugated via non-peptidyl linker to a non-glycosylated human Fc fragment. The aim of this development was to achieve increased body weight loss (BWL) compared to GLP-1R agonists while extending the half-life.

• Animal study DIO rats were treated (s.c) with HM12525A Q3D and liraglutide BID for 3 weeks, respectively. Pair-fed controls were given a daily food allotment equal to that consumed by a drug-treated group. The body weight and food intake was monitored daily. DIO mice were treated (s.c) with HM12525A QW and liraglutide QD for 4 weeks. The body weight, fat mass, and lean mass were measured.

Anti-NASH efficacy beyond GLP-1RA
METHODS • Animal study
ALIOS- and MCD-diet C57BL/6 mice were treated (s.c) with liraglutide BID and HM12525A (Q2D) for 4 weeks, respectively. After 4 weeks treatment, the hepatic TG level and liver histology by H&E staining were evaluated. In addition, TNF-D (as a inflammation marker) and collagen-1 mRNA (as a fibrosis marker) level were determined by quantitative PCR analysis from liver extracted after treatment for 4 weeks.

ALIOS or chow diet for 16 wks.
C57BL/6 1. Food Source: High fat, 55% fructose and 45% sucrose (added in water, wt/vol) 2. Expected NASH stage: Steatosis
¾ HM12525A significantly reduces hepatic TG, collagen-1and steatosis score indicating therapeutic potential for liver disease.
Figure 5. Therapeutic potential in ALIOS diet mice (n=7, 4 weeks)
• In DIO rats, HM12525A showed superior body weight loss compared with liraglutide and the potent BWL effect of HM12525A is twice than pair-fed groups indicating increase of EE
• HM12525A induces the expression of EE specific marker gene (i.e. PGC1α, NRF-1, and UCP) and mitochondria biogenesis as an action of glucagon in adipocytes and myocytes
• HM12525A reduced BW and fat mass without a change in lean body mass supporting that increasing EE may be the driving force for the potent BWL
• In NASH animal models, HM12525A reduces hepatic TG, inflammation, fibrosis marker, and histological scores
• Our results suggest that the novel GLP-1/glucagon dual agonist HM12525A may have clinical potential for the treatment of obesity and obesity-related liver disease.
¾HM12525A reduced TNF-D (pro-inflammation cytokine), collagen-1 mRNA (pro-fibrogenic marker), and NAFLD activity score more than liraglutide

• Gene expression in adipocytes and myocytes 3T3-L1 adipocytes and C2C12 myocytes were differentiated for 2 and 3 days, respectively. Cells were treated with glucagon, HM12525A or liraglutide for 24 hours. PGC1α, NRF1, and UCP gene expression were evaluated by quantitative real-time PCR analysis.
• Confocal microscopic analysis for mitochondria biogenesis 3T3-L1 adipocytes and C2C12 myocytes were differentiated for 2 and 3 days, respectively. Cells were treated with glucagon or HM12525A for 48 hours. Cells were stained with Mitotracker (Invitrogen) and Hoechst (Molecular Probes). The cell images were obtained by confocal microscopy (Carl Zeiss).
