In Vivo Imaging Solutions

Preclinical imaging is an established technology combining both functional and structural imaging to evaluate specific in vivo processes relating to spatial orientation within the model of interest. The unique characteristics of molecular imaging provide investigators with an early-stage solution to evaluate critical principles of new entity development: exposure at the target site, binding to the target of interest, and expressing the desired pharmacology. Incorporation of molecular imaging solutions into new entity development programs allows you to rapidly assess results and make essential decisions earlier in the drug development process.

In vivo imaging can be used in many development efforts, such as those targeting insight into disease processes, validity of new therapeutic targets, target/non-target organ interaction, mechanism of action, biodistribution, and others.

Answering Preclinical Imaging Fundamental Development Questions

Charles River offers a full service cyclotron in order to produce radioisotopes necessary for preclinical imaging that supports stand-alone exploratory studies or full IND-enabling programs.In drug development, a critical factor is how quickly a drug candidate will result in an effective clinical product. Our multidisciplinary scientists provide a true collaborative, translational research team to our clients. The ultimate goal is to enhance the decision-making process for clients based on evaluating three primary criteria – exposure at the target site, binding to the pharmacological target, and expression of the intended pharmacology.

Clients are then provided with an effective preclinical imaging solution that generates a translational dataset to facilitate clinical program development. When applied to early and mid-stage development, these imaging solutions answer key questions about drug candidates with just a handful of studies. Preclinical molecular imaging can provide multiple translation endpoints for product refinement for late-stage developers.

Frequently Asked Questions (FAQs) about Preclinical Imaging

  • What is preclinical molecular imaging?

    Generally speaking, molecular imaging is commonly defined as the application of radiopharmaceutical production in combination with PET and/or SPECT preclinical imaging to assess a multitude of endpoints as part of in vivo study designs. Most commonly, an anatomical imaging platform, such as CT and/or MRI, are also used to allow co-register of the PET/SPECT data sets to facilitate spatial orientation of the PET/SPECT data relative to the imaged subject.

  • How will preclinical molecular imaging help my drug development project?

    In vivo imaging solutions allows for longitudinal assessment of a single or multiple subjects across an extended duration to provide a vast number of endpoints. This allows for an efficient assessment of various aspects of the drug candidate and also reduces total number of subjects as compared to traditional preclinical approaches. This results in less time to reach critical path decisions in drug development and to also potentially reduce costs.

  • Is preclinical molecular imaging required by the FDA?

    Preclinical imaging is generally not required by the FDA or other regulatory bodies, other than for specific drug candidates, such as those intended for use as a radiotherapeutic. These guidelines for exploratory IND studies explain the support of imaging solutions.

  • How does radiochemistry support preclinical imaging?

    Advanced radiochemistry capabilities are critical to the provision of robust imaging capabilities, whether preclinical or clinical. It is essential for providers to have a wide variety of advanced techniques at their disposal to ensure the appropriate radioisotope and radiolabeling methods are applied to differing chemical entities matched to the overall intent of the study or program. Careful consideration of radiopharmaceutical solutions for individual projects and/or programs is key to program success and should include considerations for potential translation from preclinical applications to clinic where desired.
