Abstract

fetched live from OpenAlex

Lead optimization requires toxicity screening strategies to select a compound with a high likelihood of successful development. As numerous compounds need to be screened and resources to direct toward any single compound are limited, short turnaround times to generate and interpret data are needed. Utilization of in vivo toxicity screens is necessary for an effective screening strategy, however, if not appropriately implemented, they may consume excessive resources and prolong selection of a developable compound. Optimization of in vivo studies requires identifying effective placement into the screening strategy, selecting the appropriate study designs, implementing processes that allow rapid data generation and interpretation, and understanding the utilities of in vivo data. When implemented, an effective, high-throughput screening strategy will utilize adequate but minimal amounts of resources, and will prioritize processing near technical time limits. These require generating only the data from which decisions will be made and can be best achieved using as few animals as possible per study.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
