DDI Marker Studies Knowledgebase – quarterly update

The DDI Marker Studies Knowledgebase (replacing the previous combined and individual lists of CYP/P-gp substrates and perpetrators) has been updated in January 2023, and is available in the DIDB Resource Center.

We continue to expand the Knowledgebase by adding more transporter data. In this update, 18 compounds were identified as substates/inhibitors/inducers of CYP enzymes and transporters (P-gp, BCRP, and OATP1B1/3). Among them, 2 compounds could lead to strong drug interactions.

In addition to substrates, inhibitors and inducers of CYPs and transporters, the Knowledgebase provides useful information on the compounds therapeutic class, clinical recommended dosage, pharmacokinetics (e.g. dose proportionality accumulation ratio, time to steady-state), QT prolongation, and NTI characteristics.

Video Tutorials – Increased Visibility

Did you know that we have recorded 10 training videos so far, which are all available in the DIDB Resource Center?

In order to best benefit the DIDB users, the videos are now also accessible on the DIDB pages that are relevant to their content. For example, on the Drug Query page you have access to 3 related videos, on the QT Interval page to 1 related video …

Please note that you must be signed-in to access.

Feel free to suggest additional topics for training videos that you will find useful. Please contact us. Thank you.

DDI Marker Studies Knowledgebase – quarterly update

The DDI Marker Studies Knowledgebase (replacing the previous combined and individual lists of CYP/P-gp substrates and perpetrators) has been updated in October 2022, and is available in the DIDB Resource Center.

We continue to expand the Knowledgebase by adding more transporter data. In this update, 42 compounds (including 13 endogenous biomarkers) were added as OATP1B/1B3 substrates based on clinical DDI data and/or pharmacogenetic findings. In addition, 16 compounds were identified as substates/inhibitors/inducers of CYP enzymes and transporters (P-gp and BCRP). Among them, 20% could lead to strong drug interactions.

In addition to substrates, inhibitors and inducers of CYPs and transporters, the Knowledgebase provides useful information on the compounds therapeutic class, clinical recommended dosage, pharmacokinetics (e.g. dose proportionality accumulation ratio, time to steady-state), QT prolongation, and NTI characteristics.

Strong Pharmacokinetic Drug-Drug Interactions With Drugs Approved by the US Food and Drug Administration in 2021: Mechanisms and Clinical Implications

Clin Ther. 2022 Oct6;S0149-2918(22)00323-X

Abstract

This analysis aimed to identify all strong drug-drug interactions (DDIs) associated with drugs approved by the US Food and Drug Administration (FDA) in 2021.

Enzyme- and Transporter-Mediated Clinical Drug Interactions with Drugs by the U.S. Food and Drug Administration in 2021: What Can be Learned from New Drug applications Reviews?

2022 ISSX Poster Presentation – 2021 NDA Reviews

Abstract

 The mechanistic evaluation of enzyme- and transporter-based drug-drug interactions (DDIs) during drug development is critical to support management strategies in the clinic.

The objectives of the study were to review pharmacokinetic-based clinical DDI data available in the new drug application (NDA) reviews for drugs approved by the FDA in 2021, and to understand the main mechanisms that mediate interactions resulting in label recommendations. 

New features! Drug Characteristics queries expanded, and Invite a colleague to use DIDB

Drug characteristics queries are expanded from AUC-CL change queries to Drug queries. Two drug queries are now enabling users to search using object or precipitant characteristics

  • the Drug queries with Objects
  • the Drug queries with Precipitants

Invite a colleague to register to access DIDB. With this feature most of you (some restrictions apply based on the license type) can now invite a colleague from your company to register to access DIDB. Anyone working in preclinical DMPK, Clinical Pharmacology, Safety, Medical, and Regulatory Affairs can benefit from using DIDB.

When you are signed in DIDB, you can use the “invite a colleague” green button located on the right side of each of the DIDB pages, alongside the “contact us” blue button.

As always, feel free to contact us if you have any questions or comments. Your feedback is critical to make the most of the DIDB content and functionalities!
