Safety-toxicity profiles

How AI addresses common pain points experienced in the area of safety-toxicity profiles in drug development.

Introduction

Evaluating potential toxic effects of a drug candidate is a critical step in the process of taking a new drug to market. Developing a safety profile is a way to evaluate and measure toxic effects of a drug when administered at various doses over specified time periods. This process involves monitoring overall response to the drug, including any adverse reactions in target organs. Specifically, scientists will use pharmacokinetics to study how the drug moves through the body via absorption, distribution, metabolism and excretion.The stronger a drug candidate’s safety profile, the lesser the chances of adverse reactions.

Situation

When pursuing the development of novel treatments, programs tend to prioritize focus on efficacy - the safety aspect of treatments is often left to be determined after significant efficacy and PK work determines a therapeutic window, and is limited to small clinical datasets. This often results in late-stage toxicity surprises, which can be disastrous for drug developers

The VeriSIM Life advantage

Today, there’s good news for pharma researchers studying safety-toxicity profiles in drug candidates. Innovations in AI-driven technologies have allowed for the streamlining and de-risking of many aspects of early-stage drug development, including making these types of toxicity predictions.

VeriSIM Life (VSL)’s drug decision engine, BIOiSIM®, is a computational platform deploying advanced artificial intelligence and machine learning, a proprietary big data foundation, and state-of-the-art mechanistic models to predict and validate the translation of novel therapies.  

BIOiSIM, and VeriSIM Life’s associated services, can be used to problem-solve some of the most significant challenges facing early-stage drug R&D – meeting development timelines faster, at lower costs, and with better results than traditional approaches.

The BIOiSIM AI-driven technology framework supports safety/toxicity predictions and addresses the pain point of needing earlier safety-toxicity insights by:

  • Combining multiple toxicity domain predictions and PK to understand toxicity in the context of drug dosing and its concentration in organs early to better inform in vivo experimentation and program decision-making. 
  • Allows drug developers to assess dose-dependent toxicity early in the candidate development stage. 
  • Accurate toxicity predictions are performed in the context of organ drug concentration and dosing in parallel with efficacy and overall PK assessment. 
  • Guided by these insights, R&D teams can reduce experimentation to determine safety, in vivo. 
  • Utilizing chemical and biological modeling along with AI and ML techniques to provide a Translational Index™ demonstrating confidence in drug compound scenarios to de-risk and guide go/no go decisions in preclinical development and testing. This includes toxicity predictions. Accuracy is achieved through the use of 4 domains of toxicity: Clinical tox - Preclinical tox - Hepatotoxicity - Cardiotoxicity 
  • Revealing, via predictive analysis, underlying candidate features at root of toxicity signals to inform drug design decisions.

BIOiSIM advances only the most promising drug candidates through R&D to IND application,

offering actionable insights of unprecedented value to the drug development industry. Combining thousands of validation data sets, multi-compartmental models, and its integrated AI/ML engine, BIOiSIM achieves superior physiological and biological relevance within three classes of therapeutics: small molecules, large molecules, and re-engineered viruses/gene therapy.

Predicting PK/PD Profiles of NOX4 Compounds Using the BIOiSIM™ Translational AI/ML Platform

Challenge

Challenge

The subject of this case study was a client project where the BIOiSIM platform was deployed to predict the PK profiles and PD properties for the group of compounds with a similar type of pharmacological activity - inhibition of the NADPH oxidase 4 (NOX4). NOX4 inhibition has been demonstrated to be a promising approach in the treatment of fibrotic disorders and other clinical indications with accelerated lipid peroxidation leading to similar fibrotic outcomes. VeriSIM Life’s in silico approach elucidated a group of target compounds comprising the general structural commonalities suggesting high levels of NOX4 inhibition, without triggering hERG related toxicity.

Methods

Methods

BIOiSIM generated a Translational Index parallelizing predictions of PK, PD, Metabolic stability, and hERG toxicity in order to further develop a subset of NOX4 inhibiting compounds with the highest likelihood of interspecies translatability to assess drug behavior in humans, and eliminate “dead-end” compounds from further development. Simulations were run across 3 different routes of administration, and both mouse and human species.

Outcome

Outcome

With respect to human cardiotoxicity, high risk potential of hERG blockage was found across more than 50% of the test compounds, impacting the Translational Index for each, and triaging the overall consideration set dramatically. While conventional approaches will take ~2 years, VeriSIM Life, in just 4 months of modeling and simulation, computationally identified 15% of the proposed compounds as safe and efficacious by route of administration, further ranking 2 compounds as having the strongest clinical success potential.
