Drug-induced liver injury from structure
Classify whether a drug can cause liver injury, scored by AUROC on an FDA-derived set of 475 drugs.
| 1 | # Drug-induced liver injury from structure |
| 2 | |
| 3 | Liver injury has been the single most common reason for withdrawing an approved drug from the market, and it is notoriously hard to see coming. This benchmark asks whether a drug can cause it, from structure alone, on a small set curated from FDA records. |
| 4 | |
| 5 | ## Task |
| 6 | |
| 7 | Given a drug as a SMILES string, predict whether it can cause liver injury ($1$) or not ($0$). Submissions are scored by AUROC on TDC’s held-out test set, so higher is better. |
| 8 | |
| 9 | ## Background |
| 10 | |
| 11 | The set was aggregated from the US FDA’s National Center for Toxicological Research and used by Xu et al. (2015) for a deep-learning model of drug-induced liver injury; TDC includes its 475 drugs, the smallest benchmark in the ADMET group. Liver toxicity is often idiosyncratic — dependent on dose, metabolism and the patient rather than on structure alone — so high scores here deserve scepticism, and the endpoint is as much a test of honest evaluation as of chemistry. |
| 12 | |
| 13 | ## Data and evaluation |
| 14 | |
| 15 | TDC ships the group as one archive (`admet_group`, Harvard Dataverse file 4426004), loaded with |
| 16 | `admet_group(path='data/')` from the `tdc.benchmark_group` module. The group’s `dili` folder holds 379 `train_val` and 96 `test` rows (475 distinct SMILES, matching TDC’s page, with no duplicates); 49.7% of labels are positive, and 50 of the 96 test drugs are. |
| 17 | |
| 18 | The split is a scaffold split: TDC holds out a fixed 20% test set (here 96 of 475 rows in |
| 19 | the group’s files), and the remaining `train_val` part is split again per seed by |
| 20 | `group.get_train_valid_split(benchmark=name, split_type='default', seed=seed)` into 87.5% training |
| 21 | and 12.5% validation. The leaderboard asks for five independent runs with seeds 1, 2, 3, 4 and 5; |
| 22 | `group.evaluate_many` then reports the mean and the standard deviation of the per-seed test scores, |
| 23 | rounded to three decimals. The test set never changes, so only the training split moves with the seed. |
| 24 | |
| 25 | The metric is AUROC, the area under the receiver operating characteristic curve, computed by TDC’s `Evaluator(name='roc-auc')`; it equals the probability that a positive compound is scored above a negative one, and higher is better. Submissions pass continuous scores, not hard labels. |
| 26 | |
| 27 | Official evaluation code: [`tdc/benchmark_group/base_group.py`](https://github.com/mims-harvard/TDC/blob/main/tdc/benchmark_group/base_group.py) |
| 28 | in the TDC repository (MIT licence), whose `evaluate` and `evaluate_many` methods are what the |
| 29 | leaderboard numbers come from. The dataset page gives the licence as "Not Specified. CC BY 4.0". |
| 30 | |
| 31 | ## What is known |
| 32 | |
| 33 | - Best on the leaderboard: MiniMol, AUROC $0.956 \pm 0.006$ (Kläser, Banaszewski et al., 2024). |
| 34 | - Next: ZairaChem, $0.925 \pm 0.005$ (Turon et al., 2023), then AttrMasking, $0.919 \pm 0.008$ (Hu et al., 2020). |
| 35 | - Twenty entries are listed, from AUROC $0.956$ to $0.700$. The top score stands out from the pack, but on 96 test drugs one AUROC point is worth about half a compound, so the ranking below first place is close to arbitrary. |
| 36 | |
| 37 | ## What would count as progress |
| 38 | |
| 39 | - A mean AUROC on TDC’s fixed test set that beats MiniMol (AUROC 0.956), averaged over the official |
| 40 | seeds 1-5 and produced by `group.evaluate_many`, with the five per-seed numbers reported as well. |
| 41 | - The training and inference code, the environment and the fitted model, so that the five runs can be |
| 42 | repeated end to end from the `train_val` part alone. |
| 43 | - Evidence that the gain is larger than run-to-run noise: the gap between the top two entries here is |
| 44 | 0.031 AUROC, on a test set of 96 drugs, so a difference smaller than the reported standard deviation is not a result. |
| 45 | - Per-seed scores, and ideally a check on drugs withdrawn for hepatotoxicity that are not in the dataset, since 96 test compounds cannot settle this endpoint on their own. |
