PoS Benchmarks (BIO/QLS 2021)

Historical probability of success by indication and clinical stage, sourced from BIO/QLS/Informa 2021 (Thomas et al.) across 12,728 phase transitions. Evidence-based multipliers for biomarker strategy, genetic validation, orphan designation, and modality classes are applied via log-odds transformation. Methodology published in full; version-stamped on every signed export.

Baseline Stage-Transition Matrix

Phase-by-phase advancement probability per indication. Baseline cohort: small molecule × no biomarker strategy. Overall LoA = cumulative probability of approval from preclinical.

Evidence-Based Multipliers

Each multiplier is applied to the baseline PoS at the stages listed, via log-odds (logit) transformation. The source estimand (RR or OR) is disclosed alongside how the engine applies it.

Methodology Notes

  • Baseline rows are small molecule × no biomarker. Modality- and biomarker-specific values are available via the POST /benchmarks/pos/lookup endpoint (in-product, via MCP, or via authenticated API call).
  • Multipliers are applied via log-odds (logit) transformation. See the methodology page for the full derivation.
  • Preclinical PoS is never adjusted by any multiplier; NDA/BLA approval rates reflect filing quality, not drug-specific clinical attributes.
