What is Advance?
Advance service uses six integrated modules to assemble evidence regarding the added value of conducting a two-year rat carcinogenicity study, in line with the ICH S1B Weight of Evidence Addendum. With Advance, researchers can rapidly produce industry-standard carcinogenicity assessments, potentially enabling them to avoid time-consuming and costly animal-based testing. This is made possible through the analysis of comprehensive, up-to-date toxicological data, including in silico datasets.


Drug discovery is naturally time-consuming and costly, with expenses rising as development timelines lengthen. Two-year rat carcinogenicity studies are especially resource-intensive in terms of both time and money. While the ICH S1B WoE Addendum provides a pathway to avoid these burdens, assembling a regulator-ready WoE dossier is often complex and time-consuming.
Advance empowers researchers to mitigate these challenges, potentially saving millions in costs, accelerating development, enhancing safety assessments, and reducing reliance on animal testing.
Key Benefits of Advance

Advance means researchers can avoid years of carcinogenicity testing, potentially reducing time to market by 3-5 years. The service fits seamlessly into in-house workflows, further minimizing delays.
Reduces Reliance on Animal Testing
Expert-led
Advance was designed by experts with hands-on ICH S1B framework experience, ensuring the delivered service is scientifically robust, regulator-aligned, and grounded in real-world drug development needs.
Lowers Costs
Scalable
Core Modules
Advance offers a robust suite of modules designed to assess the safety and efficacy of drug candidates throughout the development process. With solutions for target biology, secondary pharmacology, histopathology, and more, Advance provides several tools that deliver comprehensive insights into potential risks such as tumor development, toxicity, and immune modulation, ensuring a thorough evaluation of both therapeutic and safety profiles.

Target Biology
This module evaluates whether the drug target has a known role in tumor development. It integrates expression profiles, pathway analysis, and translational evidence from human and animal data to assess oncogenic potential.

Secondary Pharmacology
Evaluates off-target interactions using in vitro binding assays and computational predictions. The module identifies unintended pharmacological effects potentially linked to tumor development, supporting comprehensive risk assessments.

Histopathology

Hormonal Perturbation

Genotoxicity
Integrates genetic toxicology data from in vivo assays, including micronucleus and comet assays. Such testing helps determine a substance’s potential to cause DNA damage, a key factor in evaluating carcinogenic risk.

Immune Modulation
Why Choose Advance?
Advance can be strategically integrated throughout the various stages of research and development, providing researchers with dynamic tools to collect data for WoE summary submissions. The six Advance modules, developed by experts, are each tailored to specific aspects of the WoE process. This enables our team of experts to collaborate with researchers to create comprehensive, regulator-ready documents, significantly increasing the chances of successfully demonstrating product safety.
With the potential to save years of effort and millions of dollars, Advance is a compelling choice for researchers aiming for strong ROI and accelerated development timelines. The service automates data mining and streamlines the review and interpretation of information, allowing essential safety insights to be generated much faster and more efficiently than traditional methods like manual data collection and organization.
Customer Success Stories
In March 2022, a pharmaceutical company developing a late-stage compound engaged Instem to assess carcinogenicity risks linked to its drug’s primary target. Instem collaborated closely with the client, defining the scope and delivering review drafts by the summer of 2022.
By October, Instem’s Drug Target Carcinogenicity Risk Assessment, combined with client insights, supported a WoE summary submitted to the FDA. The FDA accepted the supplemental NDA in January 2023.
By May 2023, the drug had successfully reached the market. Instem’s expertise in biological data mining and risk cataloging played a pivotal role in expediting regulatory approval and ensuring patient access to the new treatment.

How It Works
Advance can be implemented at any stage of the development process. Its flexible design allows clients to assess a single guideline-defined factor or all six, with the ability to combine data as needed. Automated data mining integrates seamlessly with in-house data, delivering instant insights from complex inputs. As new studies are conducted and data is generated, it can be continuously added to a growing, regulator-ready dossier, streamlining preparation for WoE summary submissions.
