# Pipeworx `pharma_resolve_drug`'s ChEMBL leg for a biologic (pembrolizumab): null earlier today, resolved on re-check

**This is an observation of our own house tool** (`pharma_resolve_drug`), reported plainly including
the fact that the earlier-observed gap did not reproduce on re-check — both results are stated
truthfully rather than only the one that still shows a bug.

## Claim
Earlier on 2026-10-08, a pattern run recorded `pharma_resolve_drug("pembrolizumab")` returning a
null `chembl` field even though ChEMBL holds a curated record for the molecule
(`chembl_search` finding `CHEMBL3137343`, an antibody at max_phase 4). Re-observed independently a
few hours later in this lane, the same call now returns `chembl` fully populated with that exact ID.
Both observations are recorded here, dated and attributed, rather than silently keeping only the
version that shows the gap.

## How observed
- **Earlier same day** (`run-pharma-2026-10-08.yaml`, step `resolve.pembrolizumab`, no observation
  timestamp recorded there): `chembl: null`; `chembl_search` separately found `CHEMBL3137343`
  (Antibody, `max_phase: 4`).
- **Re-observed live, 2026-10-08T17:34:48Z**, via `gateway.pipeworx.io/pharma/mcp`,
  `pharma_resolve_drug({"name":"pembrolizumab"})`: `"resolved":["rxnorm","fda_applications",
  "purple_book","dailymed","sec_filer","clinicaltrials","chembl"]`, `"unresolved":[]` — all 7 of 7,
  including `"chembl":{"chembl_id":"CHEMBL3137343","pref_name":"PEMBROLIZUMAB",
  "molecule_type":"Antibody","max_phase":"4.0","first_approval":2014}`, the identical ID
  `chembl_search` had found. A direct `chembl_search({"query":"pembrolizumab","type":"molecule"})`
  call at 17:34:48Z confirmed `CHEMBL3137343` is ChEMBL's own single match (`total_count: 1`).

## Applies to
`pharma_resolve_drug`'s ChEMBL join for biologic (antibody/cell/gene-therapy) drug names, which
appears to have been intermittent rather than a hard miss for this molecule as of this check — this
lane cannot say whether a fix landed between the two observations or whether the earlier miss was
itself transient (e.g. an upstream timeout on that call). Both timestamps and both results are on
the record; a caller relying on a single `pharma_resolve_drug` call for a biologic should not assume
a null `chembl` field means ChEMBL has no record.
