Comparative Medicine Services Core

CMSC LogoOverview of Services

Since its inception, the CHOP Research Institute has held a “bench to bedside” philosophy that emphasizes bringing basic research ideas to the clinic so that they may improve the lives of our patients and their families.  Completion of nonclinical investigations and submission of an Investigational New Drug (IND) application or a Premarket Approval (PMA) application to the FDA for the approval of first-in-human clinical trials are essential steps toward enacting this philosophy.  The mission of the Raymond G. Perelman Center for Cellular and Molecular Therapeutics Comparative Medicine Services Core (CMSC) is to partner with and guide investigators through these processes.

The Comparative Medicine Services Core is currently developing the capacity for GLP-compliance.  All nonclinical programs require in-depth planning and discussions.  Therefore, we encourage you to contact us as soon as you believe you have a drug or device that will eventually require human clinical trials prior to use in patients.  The Comparative Medicine Services Core is composed of highly-trained professionals capable of completing and overseeing a variety of animal studies.  We adhere to the highest standards of animal welfare, procedure reproducibility and validation, and customer service.

The Comparative Medicine Services Core staff can assist you with all stages of your nonclinical study program, including:

  • Grant Preparation
  • Budget Preparation
  • Facilitating Type A, B, & C meetings with the FDA
  • Experimental Design
  • Study Protocol Drafting and Management
  • IACUC protocol advice
  • SOP Development, Management, and Archiving
  • GLP Training Delivery and Record Keeping
  • Comprehensive Quality Assurance Activities
  • Study Execution and Data Generation
  • Archiving of Study Materials and Data

The Comparative Medicine Services Core specializes in, but is not limited to, the following types of studies:

  • Pharmacokinetic Studies
  • Biodistribution Studies
  • Toxicology and Reproductive Toxicology Studies
  • Medical Device Testing
  • Surgical Model Development
