Forecast HTA reimbursement decisions and conditions before you file.

Loon Waters connects clinical evidence to coverage decisions. Monte Carlo Committee Simulation models how HTA and payer committees deliberate — anticipating outcomes, conditions, and coverage requirements while your strategy can still change.

See the evidence

Evidence that lands.

Committee outcomes stay a blind spot until the hearing.By then it is too late to fix the submission.

Approved therapies wait 2–5 years for reimbursement, and biopharma loses an estimated $33.5 billion annually to the delays. Risk is typically identified late — post-submission, pre-hearing — when options for course correction are limited.

Loon Waters replaces opinion-based advisory with a structured, objective pressure-test: Monte Carlo simulation of how HTA committees will deliberate on your dossier, while your strategy can still change.

The platform

From clinical evidence to committee decision

Loon Waters

Value simulation, reimbursement and conditions forecasting

Connects clinical evidence to downstream value and coverage decisions. Monte Carlo Committee Simulation models how payer committees deliberate — anticipating outcomes, conditions, restrictions, and coverage requirements before filing.

  • Forecast specific reimbursement conditions before committee review
  • Stress-test value dossiers and submission strategies across jurisdictions simultaneously
  • Quantify how evidence, price, and ICER changes affect HTA deliberations

Loon Waters — reimbursement forecasting

Capabilities

Reimbursement & conditions forecastingForecast recommendations and the specific conditions attached to them — before committee review, for every jurisdiction in scope.
Value dossier development & optimisationPrepare, assess, and continuously update value dossiers — quantifying how evidence, price, and ICER changes shift deliberations.
Joint Clinical Assessments (JCA)EU JCA readiness — eligibility criteria and evidence strategy stress-tested for every PICO before they land in the dossier.
HTA submission supportRun mock submissions and scenario analyses across jurisdictions to optimise launch sequencing and de-risk filing.
Committee-decision simulationPersona-modelled committees deliberate your dossier across thousands of runs — objection mapping, decision drivers, and evidence gaps.

How it works

A structured simulation of HTA committee deliberation

Advanced Monte Carlo simulation and sampling with the proprietary Loon AI® engine, interpreted with ex-HTA insider expertise. Not generative commentary. Not a black-box score.

InputWhat we ingest
  • Clinical evidence package
  • Economic parameters
  • Target population & positioning
SimulationWhat we run
  • Committee persona modelling
  • Objection probability mapping
  • Recommendation & conditions
OutputWhat you receive
  • Risk band: low, moderate, or high
  • Vulnerability heatmap & objection themes
  • Evidence gaps & mitigation options

Iterate before you file. Run scenario analyses to assess how strategic adjustments shift predicted outcomes and condition profiles — before submission.

Deliverables

01Executive intelligence briefAt-a-glance risk summary with key insights — calibrated for committee, executive, and access-team review.
02Objection mapping & decision-space analysisQuantified areas of concern with detailed root-cause tracing — and the levers available to address them.
03Predicted reimbursement conditionsConfidence scores, rationale, and likelihood for each condition — so teams know where to focus.
Optional add-ons:In-depth Q&A debriefScenario analysesObjection handling

Calibrated confidence

The only AI that knows when it is uncertain

Every Loon Waters prediction carries a calibrated confidence score. The system distinguishes high-confidence predictions from uncertain ones — so access teams know which findings to act on and where expert judgement should focus.

Stratified by Strength of Mandate, high-confidence predictions reached 96.8% accuracy — so strategic effort lands on the submissions and conditions where risk is real.
