We offer a full range of IND/BLA/NDA-enabling toxicology and bioanalytical services, providing powerful tools and rigorous solutions to find the answers you’re looking for 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 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 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



    The partner you select to characterize the toxicological profile of your new therapeutic entity can be a difference-maker since it is a key component of your safety assessment program. With over 25 years of experience, our scientific team has the expertise to help you make better decisions, faster.

  • 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 submissions, our experienced team can assist you in identifying and minimizing potential risks earlier, so that you can advance your best molecule.

  • Subchronic/Chronic Toxicity Testing

    Sub-Chronic/​Chronic, Repeated Dose Toxicity

    Sub-Chronic/​Chronic, Repeated Dose 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 program needs.
