How it’s built

Biotica Bio assessments are reproducible by design: one GraphQL query against the Open Targets Platform returns structured evidence (target, pathways, disease associations, druggability, safety, DepMap, literature, and more). We turn that data into a narrative report—so you get both the evidence and the interpretation.

Flow

1. One query — We run a comprehensive oncology target assessment query (or a variant for your use case) against the Open Targets Platform GraphQL API.
2. Structured data — The API returns JSON: genes, pathways, associations, known drugs, tractability, prioritisation scores, safety, expression, genetic constraint, literature counts, and more.
3. Narrative report — We interpret that data and write the executive summary, strategic points, and recommendations you see in reports like the BRCA2 example.

Same query, same data—you can re-run as evidence updates or have your own team audit the inputs. For the BRCA2 example, the response was generated from oncology-result.json; the narrative was added for executive use.

The query

The BRCA2 report used the following GraphQL query (target ID ENSG00000139618). You can run it in the Open Targets GraphQL Playground or in your own environment. For the Platform’s entities and how they are queried (target, disease, drug, variant, study), see The platform → Entities and query space.

The query file is in this repository at scripts/queries/oncology-target-assessment.graphql. To regenerate the report from the API, run the scripts in scripts/ (see scripts/README.md).

Reproducibility

• Same query, same API — Anyone with access to the Open Targets Platform can re-run this query and get the same evidence base.
• Updates — When Open Targets or upstream sources release new data, re-running the query and regenerating the report keeps the assessment current.
• Audit — The methodology is transparent: data from the Platform; interpretation and narrative by Biotica Bio.
