Discovery, Development &
Preclinical Studies
LIPAGLYNTM
A novel, first-in-class NCE with
beneficial effects on both lipid
and glycemic parameters
A milestone in Indian history……
Lipaglyn™ is world’s first approved dual
PPAR-α/γ agonist
LipaglynTM is completely different in structure and
attributes from TZDs/Glitazones

LipaglynTM binds more strongly to PPAR- α
than Fenofibrate
LipaglynTM
Fenofibrate
LipaglynTM : Stronger binding with PPAR-α as a result of 4 H-bonding sites
as against only 2 H-bonding sites in the case of Fenofibrate
LipaglynTM: ‘A million times’ more potent in
activating PPAR- than Fenofibrate

Saroglitazar is a potent and predominantly PPARα agonist
with optimal PPARγ agonistic activity

PPAR agonists are not a class of drugs, each
drug has unique properties*
Dr. Steven Nissen at
ADA Meeting, 2012
“The binding of different ligands to Nuclear
Receptors induces different conformational
changes. Each drug has a characteristic co-factor
binding pattern.”

LipaglynTM was extensively profiled for efficacy
in various preclinical models of dyslipidemia
Models of diabetes & insulin resistance
- db/db mice
- Zucker fa/fa rats
Nondiabetic animal models
-
Swiss albino mice
High fat-high cholesterol diet-fed Golden Syrian hamsters
High cholesterol diet-fed Sprague Dawley rats
Nonhuman Primate (Marmosets)
LipaglynTM reduces serum triglycerides in a dosedependent manner in various animal models
Zucker fa/fa rats
Diabetic animal models
db/db mice
High fat-High Cholesterol Diet Fed Hamsters
Nonhuman Primates (Marmosets)
Non-diabetic animal Models
Swiss albino mice mice
Diabetic & Insulin Resistant Models
• Up to 55% TG reduction in db/db mice
• Up to 86 % TG reduction in Zucker fa/fa rats
•
•
•
•
Non-diabetic Abimal Models
Up to 76 % TG reduction in Swiss Albino Mice
Up to 90 % TG reduction in High fat-High cholesterol-fed Hamsters
Up to 61% reduction in serum triglycerides in Primates
LipaglynTM improved lipid clearance and
reduced serum cholesterol levels
Improved Lipid Clearance in Swiss Albino Mice
High Cholesterol Diet Fed Sprague Dawley rats
• Up to 68% improvement in lipid clearance in Swiss Albino mice
• Up to 77 % reduction in serum cholesterol in high-cholesterol diet-fed Sprague Dawley rats
• Potential for Post prandial hyperlipidemia
LipaglynTM also has anti-diabetic effects
in various animal models
•Effects in db/db mice
•Effects in Zucker fa/fa rats
•Glucose Clamp study in Zucker fa/fa rats
for Insulin sensitizing effects
LipaglynTM showed anti-hyperglycemic and insulin
sensitizing effects in diabetic & insulin resistant animals
(db/db mice and Zucker fa/fa rats)
Effect on AUCglucose in OGTT
Effect on Serum Insulin

Preclinical Evidence of Safety
• All Preclinical toxicity studies conducted in GLP
(OECD) certified lab (Global quality standard)
• Our research center (ZRC) also has AAALAC, NABL &
CAP accreditation
• Data acceptable globally
OECD - The Organization for Economic Co-operation and Development
AAALAC – Association for Assessment and Accreditation of Laboratory Animal Care International
NABL – National Accreditation Board for Testing and Calibration Laboratories
CAP – College of American Pathologists
Safety pharmacology studies show that LipaglynTM does not
affect CNS, CVS, Respiratory and GI functions
Extensive toxicity studies including 2 yr
carcinogenicity study have shown no safety concerns
Overall Conclusions of Preclinical Safety &
Toxicity Studies
• LipaglynTM is safe and well tolerated
• No hepatotoxicity, myotoxicity, nephrotoxicity or cardiotoxicity at
doses equivalent to or higher than efficacy doses
• Non-genotoxic & Non-teratogenic
• Passed 2-year carcinogenicity study (confirmed by a mechanistic
study using non-human primates employing molecular biomarkers).
