# ChEMBL's own `max_phase` field can sit a full clinical phase behind the trial registry for the same molecule

**Fair to the tool:** this is an observation of ChEMBL's own curated data (both via Pipeworx's
`chembl_search` and directly against ChEMBL's own web services), not a bug in how Pipeworx surfaces
it. ChEMBL is a curated database with its own update cadence; a lag is expected behavior of a
hand-curated resource, not a defect.

## Claim
ChEMBL's `max_phase` for a molecule is a curated field that can lag a full phase behind what the
same molecule's own registered clinical trials show, including trials that have been active for
years and a biologics-license application already under FDA review.

## How observed
Re-observed live, 2026-10-08T17:34:50Z–17:35:12Z:
- `chembl_search`/`pharma_resolve_drug` on `deramiocel` → ChEMBL id `CHEMBL6068233`, `molecule_type:
  "Cell"`, `max_phase: "2.0"`.
- Direct GET against ChEMBL's own web service, 2026-10-08T17:35:10Z:
  `https://www.ebi.ac.uk/chembl/api/data/molecule/CHEMBL6068233.json` → `"max_phase":"2.0"`
  (confirms the Pipeworx-surfaced value is exactly what ChEMBL's own API returns — no transformation
  in the middle).
- `ct_search({"query":"deramiocel"})` returns 3 studies, including `NCT05126758`
  ("A Phase 3, Randomized, Double-Blind, Placebo-Controlled Trial …"), `status:
  "ACTIVE_NOT_RECRUITING"`, `phase: "PHASE3"`, enrollment 106, start 2022-06-22.
- Direct GET against ClinicalTrials.gov's own v2 API, 2026-10-08T17:35:11Z:
  `https://clinicaltrials.gov/api/v2/studies/NCT05126758?fields=protocolSection.statusModule.overallStatus,protocolSection.designModule.phases`
  → `{"overallStatus":"ACTIVE_NOT_RECRUITING","phases":["PHASE3"]}` — confirms directly against
  ClinicalTrials.gov's own data, independent of any Pipeworx tool.
- Matches the earlier same-day run's note (`run-pharma-2026-10-08.yaml`, step
  `resolve.deramiocel.problems`) that a BLA was separately reported under FDA review for this
  molecule; this lane did not re-verify the BLA/PDUFA claim (no `fda_applications` entry was
  returned by `pharma_resolve_drug` for deramiocel — `"fda_applications":[]`), so only the
  ChEMBL-vs-CT.gov phase gap is asserted here as independently confirmed.

## Applies to
Any cell/gene-therapy or other advanced-modality molecule whose ChEMBL curation has not caught up
to its current trial phase; `max_phase` should be read as "the phase ChEMBL has recorded," not "the
molecule's current phase." A caller needing the live phase should cross-check a trial registry
directly rather than trusting ChEMBL alone for fast-moving pipeline assets.
