Candidate Selection and Chemistry Development

Designing Preclinical Programmes That Enable Clinical Translation

Non-clinical studies are an essential part of the development of novel radiotracers and theranostics.

Increasing regulatory focus on the scientific relevance and translational justification of preclinical data means that careful consideration must be given to study design, model selection, and the overall impact of generated data on the downstream clinical development pathway.

Whether evaluating basic proof-of-principle biodistribution, tissue pharmacology, dosimetry or therapeutic efficacy, CITRAS provides expert support in both the design and critical review of non-clinical programmes.

Regulatory-Relevant Study Design

Regulators increasingly expect:

Scientifically justified study rationale

  • Appropriate species and disease model selection

  • Clear translational linkage to intended clinical use

  • Robust statistical and analytical planning

  • Data that meaningfully supports IND/IMP submissions

Poorly designed studies can introduce delay, increase cost and generate non-actionable data.

CITRAS ensures that non-clinical investment directly supports regulatory and clinical progression.

Areas of Support

  • Study design strategy

  • Selection of AAALAC-accredited sites

  • Definition of requisite preclinical studies to enable clinical translation

  • Scientific review and protocol optimisation

  • Technology transfer and method development support

  • Troubleshooting and root cause analysis

  • Data interpretation

  • Report review and regulatory alignment

Where required, CITRAS can recommend and coordinate with experienced global partners to ensure execution meets both scientific and regulatory standards.
