Radiopharmaceutical therapies represent an effective way to treat solid cancers by using tumor targeting small molecules, peptides or biologics to deliver a cytotoxic payload that induces DNA damage in tumor cells, while limiting damage to normal and healthy tissue.

Streamlined development, evaluation and clinical translation of radiopharmaceuticals requires a partner that has extensive scientific, regulatory and operational expertise. Working with a CRO that provides a complete solution ensures data is delivered in a timely manner to make a go/no-go decision on your imaging or
therapeutic candidates.

Services Include:

  • Single-site, first-in-human through multi-site, late phase clinical study support
  • Investigational New Drug (IND)/Clinical Trial Application (CTA) submission support with clinical protocol development
  • Preclinical and clinical dosimetry and advanced quantitative image analysis
  • Radiochemistry development – conjugation, radiolabeling, stability and immunoreactivity
  • Preclinical proof-of-concept studies – biodistribution, efficacy, toxicology
  • Good manufacturing practice (GMP) radiochemistry development and production support for imaging agents

Preclinical Radiopharmaceutical Therapy Solutions

Bringing new therapeutic radiopharmaceuticals to the market is a complex and challenging process. When filing an Investigational New Drug (IND) or Clinical Trial Application (CTA) prior to the initiation of human trials, it is crucial to have strong non-clinical data to support a new candidate.

Invicro provides complete preclinical support of your project, including:

    • Study design and consultation
    • Radiolabeling/conjugation to support alpha, beta, and gamma emitting isotopes
    • in vitro/ex vivo cell and tissue-based assays
    • Primary pharmacology studies to demonstrate MOA
    • in vivo Imaging model development to support theranostic imaging
    • Advanced image analytics
    • Dosimetry
    • IND support
    • Development of chemistry, manufacturing and controls package for imaging agents
