Abstract

fetched live from OpenAlex

The properties of a new drug are set at the point of design, including any potential design flaws. Many small molecules that make it to human trials fail to progress beyond Phase 1 due to these flaws, which manifest as unacceptable side effects (either alone or in combination), meaning the drug (and therefore the pathway it is modulating) can never be adequately evaluated. This presentation will highlight how, through the thoughtful generation of a precise target candidate profile (TCP) and the subsequent use of GenAI, clinical candidates can now be precision designed to more exacting standards. Such molecules have the potential to have improved therapeutic indices, even against protein targets that are usually associated with mechanism-based adverse events. Citation Format: David J.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
