Rat Studies

A Larger, More Human-Like Rodent

The rat model is the quintessential system for regulatory-driven toxicology and complex pharmacology, prized for a well-characterized physiology that provides robust, translatable data. BioLegacy leverages this cornerstone model to its fullest potential in pivotal GLP-compliant safety pharmacology, advanced neurobehavioral studies, and surgically induced models. BioLegacy works with all national breeders and can procure immunocompromised animals or genetically modified rats from dedicated partner labs. Our deep expertise delivers the comprehensive toxicokinetic, safety, and efficacy data packages required to de-risk your program and ensure a confident transition to IND.

  • ICH-Compliant Safety Pharmacology: Core battery assessments including continuous cardiovascular monitoring via implanted telemetry for precise hemodynamic and ECG analysis.
  • Advanced Neurobehavioral & Cognitive Testing: Validated models of psychiatric and neurodegenerative disorders with complex behavioral testing.
  • GLP-Compliant Toxicology: Industry-standard, IND-enabling repeat-dose toxicology studies.
  • Complex Surgical & Disease Models: Sophisticated models like middle cerebral artery occlusion (MCAO) for stroke research.
  • Metabolic & Cardiovascular Disease: Established diet- and chemically-induced models of diabetes, dyslipidemia, and hypertension.
  • DART (Developmental & Reproductive Toxicology): A validated rodent species for the full suite of reproductive toxicology studies.
  • Full Bioanalytical & Pathology Integration: Seamless in-house support for TK/PK analysis and expert pathological interpretation of study endpoints.
GLP Toxicology & Safety Pharmacology

The rat is the cornerstone of preclinical safety assessment, and studies executed by BioLegacy are designed to generate the unimpeachable, GLP-compliant data required for global regulatory submissions. Our comprehensive suite of toxicology and ICH-compliant safety pharmacology studies leverage the rat’s well-characterized physiology to deliver a definitive profile of your compound’s safety. Our deep expertise in this essential model ensures robust, submission-ready data to de-risk your program and accelerate its path to the clinic.

  • Pivotal repeat-dose toxicology studies (28-day, 90-day, etc.)
  • ICH S7A/B-compliant safety pharmacology core battery
  • Cannulated infusion pharmacokinetics (PK)
  • Integrated toxicokinetic (TK) and bioanalytical support
  • Developmental and Reproductive Toxicology (DART) studies
  • Full SEND Datasets (in conjunction with our partners) and regulatory-ready reporting
Neuroscience & Behavioral Pharmacology

For CNS therapeutics, a nuanced understanding of behavioral and cognitive effects is critical. The rat’s sophisticated behavioral patterns make it an ideal model for these complex assessments. BioLegacy provides a comprehensive platform for neuropharmacology, offering a wide array of validated disease models and a battery of sensitive behavioral tests to evaluate the efficacy of your CNS-targeted compound and elucidate its mechanism of action.

  • Advanced Neurobehavioral and Cognitive Tests: Wide range of tests for assessing neurological & cognitive function.
  • Validated Models for Neurodegenerative and Psychiatric Disorders including multiple sclerosis, CNS inflammation, and seizure / epilepsy
  • Spinal Cord Injury Models including complex, surgically-induced models.
  • Drug Delivery & CNS Access Testing including intracerebroventricular, stereotactic, and intrathecal delivery
Cardiovascular, Metabolic & Surgical Models

The rat’s larger size and well-understood physiology make it an invaluable model for a range of systemic diseases and for studies requiring surgical induction. Our industry-leading expertise in precise microsurgeries, enables a diverse portfolio of cardiovascular, metabolic, and other surgically-induced disease models. By integrating these exactingly executed models with in-depth functional and biomarker analysis, we provide a clear, quantitative assessment of your therapeutic’s efficacy.

  • Cardiovascular Telemetry for hemodynamic and ECG monitoring
  • Heart Failure and Myocardial Infarction Models: Surgically induced models
  • Obesity, Diabetes, and Dyslipidemia: Diet-induced and genetic models
  • Models of Arthritis such as collagen-induced arthritis (CIA), and other inflammatory diseases
  • Renal Disease Models including 5/6 nephrectomy for chronic kidney disease (CKD)
  • Vascular Injury and Remodeling Studies including heart transplant studies
