Biopta company presentation

Ethically-donated fresh, functional human tissues can be used to better predict the likely effect of drugs during clinical trials. As the closest possible model of drug function in patients, fresh human tissues are playing an increasingly important role in de-risking the drug discovery process, helping pharmaceutical and biotechnology companies to make earlier go/no-go decisions based on human data.

Biopta company presentation

  1. 1. The Use of Fresh Human Tissues to Predict Drug Efficacy, Safety and Absorption
  2. 2. Human Tissues Predict Clinical Safety and Efficacy • Functional data produced in ex vivo human tissue • Provide information to pharmaceutical and biotechnology companies about the behaviour of their compounds in human relevant systems • Efficacy • Do compounds work in human tissue • Absorption • Are compounds permeable through human gut, skin, bronchi • Safety Pharmacology • Do compounds show adverse effects in human tissue – e.g. human coronary arteries • Comparative studies with other species strengthens this capability
  3. 3. Biopta- Leaders in Fresh Human Tissue Research Beltsville, Maryland Glasgow, UK• HQ and lab in Glasgow, UK • Lab facility in Maryland • Founded 2002 • First, and currently only, GLP compliant functional human tissue CRO • Experts in human tissue research and procurement • 50% of scientists at PhD level • Pharma and Biotech customers worldwide • Tailored human functional studies with responsive and flexible collaboration to achieve clients’ goals
  4. 4. Biopta’s Tissue Network: Fresh Human Tissues Sourced 24/7 in USA and UK Surgical residual tissues Nontransplantable organs • Biopta receives ethically donated fresh tissues via two main routes: - Surgical residual tissues (mainly UK) -Non-transplantable organs (mainly USA) • Biopta’s facilities are open 24/7 to receive the tissues, dissect and conduct experiments – Laboratories ( ) placed strategically to minimise transport time • Biopta is an ethically approved Research Tissue Bank
  5. 5. Biopta’s Scientific Expertise: Techniques to Assess Human Tissue Pharmacology • Biopta has a track record of producing high quality decision-making data from human and animal tissue in a variety of functional assay systems • Experience with addressing complex issues across a broad range of therapeutic areas and mechanistic pathways • Staffed with highly trained laboratory scientists skilled in tissue dissection and experimentation, and with experienced study directors with a track record of coordinating complex programs of work
