  • Nucleic acid therapies
  • Genome editing technologies
  • Animal health products


We offer a full range of IND-enabling studies and BLA/NDA-enabling toxicology and bioanalytical services, providing powerful tools and rigorous solutions for preclinical drug development as you evaluate therapeutic candidates, advance lead compounds toward first-in-human trials, and support ongoing clinical development.

  • Lead Optimization Services



    We investigate specific drug characteristics to identify optimal candidates for clinical success.

  • Preclinical Pharmacology Services



    Our pharmacological testing predicts biological effects of new therapeutic entities, supported by our extensive bioanalysis capabilities.

  • Pharmacokinetics and Pharmacodynamics Testing

    Pharmacokinetics/ Pharmacodynamics

    Pharmacokinetics/ Pharmacodynamics

    Our team of scientists is adept at evaluating PK/PD parameters for the characterization of active substances on a test system and understands the importance of selecting the right candidates for preclinical drug development.

  • Acute Toxicology Studies - Acute Toxicity

    Acute Toxicology

    Acute Toxicology

    A well-designed, streamlined acute toxicity study by Altasciences can help predict likely target organ toxicity and help with dose selection for initial repeat dose toxicity tests. We offer efficient preclinical drug development study designs that honor the three Rs of animal welfare (replacement, reduction, refinement), while ensuring that proper scientific rigor is achieved.

  • Dose Range Finding Studies

    Dose Range Finding/​Maximum Tolerated Dose

    Dose Range Finding/​Maximum Tolerated Dose

    Through a rapid assessment of the toxicological profile of your new therapeutic entity, we will help you establish initial safety — facilitating subsequent regulatory toxicological studies.

  • Repeated-Dose Toxicity Studies - Preclinical Toxicity Testing

    Repeat-Dose Toxicity Testing

    Repeat-Dose Toxicity Testing

    Our expertise in preclinical toxicology studies supports the advancement of your development program through the repeated dose toxicity tests, ensuring that you have the robust safety testing data needed. Toxicity studies in clinical trials pay a crucial role in supporting development decisions, and our repeat dose toxicity experience will help get you there.

  • Safety Pharmacology Studies -  Safety Pharmacology Services

    Safety Pharmacology

    Safety Pharmacology

    Let us help you assess the impact of your therapeutic entity on vital organ systems before first-in-human testing. To support your IND-enabling, our experienced team can assist you in identifying and minimizing potential risks earlier, so that you can advance your best molecule through preclinical drug development and beyond.

  • Subchronic/Chronic Toxicity Testing

    Sub-Chronic/​Chronic Toxicity

    Sub-Chronic/​Chronic Toxicity

    If your therapeutic entity is intended for repeated or chronic use in patients, we can test it for any adverse effects over extended periods of time, as per your preclinical drug development program needs.

Preclinical Services - FAQs

Which preclinical drug development studies do you offer?

Single dose/acute, dose range finding, sub-chronic dosing, chronic dosing, carcinogenicity, safety pharmacology, toxicology, PK/PD. Most studies that you need for your IND enabling program can be conducted at Altasciences.

Do you offer supporting services for preclinical drug development?

We offer scientific, regulatory and strategic guidance, protocol development, project management, analytical chemistry, bioanalysis for small and large molecules, toxicokinetics, anatomic pathology, clinical pathology, reporting, SEND, and archiving of your preclinical research samples.

How do you ensure the 3Rs are applied when conducting preclinical drug development studies?

We have an innovative, robust animal welfare program that ensures the 3Rs are rigorously applied, and that the physical and mental safety of our test animals is at the forefront of our activities. All employees sign a pledge to honor the animals in our care. Read a recent e-Bulletin for access to our animal welfare and preclinical research videos, which offer a more in-depth look at what we do.

Do you work with both rodents and non-rodents for preclinical drug development programs?

Yes we work with both small and large animals, for all your preclinical research needs. Our facility is equipped with 140 animal rooms, including European Housing, and we are constantly working to develop innovative and reduced-stress methods of working with our non-human primates.

Do you offer preclinical to clinical integrated development programs?

Yes we do. When you partner with us for an integrated, end to end program, we design the clinical studies to use the preclinical data to best advantage. We ensure a constant flow of communication and open collaboration so that you only have to Tell Us Once(™) and then we take care of the rest.

Working as a flexible, attentive extension of your team, we offer comprehensive drug development services to move your molecule forward.
