Preclinical Development

What is Preclinical Development?

Preclinical development is the stage of research that occurs before clinical trials in humans, during feasibility, testing, and safety data are collected, typically through laboratory studies.

The main goals of preclinical development are:

  • To determine a safe starting dose for first-in-human studies
  • Assess potential toxicity of the product, which can include new drugs, devices, and diagnostics.
  • Develop a new drug scale up
  • Support the intended clinical trail

What is the difference between preclinical development and clinical development?

Preclinical DevelopmentClinical Development
Occurs before testing in humansInvolves testing in human subjects
Uses laboratory animals and in vitro studiesConducted in human clinical trials
Aims to determine a safe starting dose and assess potential toxicityEvaluates efficacy and further assesses safety in patients
Generates data for Investigational New Drug (IND) applicationGenerates data for New Drug Application (NDA) for marketing approval
Adheres to Good Laboratory Practices (GLPAdheres to Good Clinical Practices (GCP)
Includes pharmacology, pharmacokinetics, and toxicology studiesDivided into phases (Phase 1, 2, 3, 4)
Typically involves rodent and non-rodent animal modelsInvolves human subjects, often starting with healthy volunteers

Why is preclinical development important in pharma?

Preclinical development is essential for evaluating the safety and efficacy of drug candidates before human testing. It identifies potential adverse effects, determines safe dosages, and provides preliminary evidence for further testing. Regulatory agencies require comprehensive preclinical data to ensure safety for human trials, helping companies comply with legal standards. Early issue identification saves time and resources, avoiding costly failures in later phases. Additionally, preclinical data informs clinical trial design and strengthens intellectual property by supporting patents. In summary, preclinical development is vital for ensuring that safe and effective drug candidates reach the market.
