Preclinical datasets

DIDB Clinical datasets

The preclinical (human in vitro) datasets contain results from both in vitro metabolism and in vitro transporter studies.

  Metabolism and Transport datasets

The preclinical datasets contain results where a drug is tested as an inhibitor/activator/inducer (precipitant) or a substrate (object) for a given human drug metabolizing enzyme or transporter (including variants).

Kinetic parameters (such as Papp, efflux ratio, uptake ratio, CLint, Km, and Vmax), inhibition and induction values (such as IC50, Ki, % inhibition or fold increase, Emax, and others) and in vitro-to-in vivo prediction ratios per FDA DDI guidance, are extracted from published citations and NDA/BLA reviews. Additionally, detailed experimental conditions (cell type, precipitant and substrate concentrations, etc.) are included for each study.

Study results are organized according to the overall effect and mechanism of the interaction and includes negative study results (classified as a non-inhibitor, non-inducer, or non-activator as appropriate). This data capture not only the effect on the drug as a substrate, but for the drug as a perpetrator as well.

Multiple queries allow users to retrieve an in vitro dataset by drug name, enzyme name, or mechanism of the interaction (drug as precipitant or as object).

Results can be viewed, customized, and downloaded in multiple formats, allowing users to compile and organize the large body of information available.

Work faster and smarter

What subscribers are using the preclinical datasets for:

  • PROVIDE CONTEXT for RESULTS OBTAINED for candidate compounds
    inter-lab, substrate- and system-dependency, etc.
    with input parameters
    cell system, incubation conditions, test concentrations, choice of substrate/inhibitor, etc.
  • ASSIST with DOSE SELECTION for clinical trials
  • PROVIDE IN VITRO EVIDENCE to EXPLAIN CLINICAL RESULTS and improve understanding of drug interaction mechanisms
