Octozi vs QuantHealth
Two applications of models to clinical development that sit on opposite sides of the moment a protocol is locked. QuantHealth simulates the trial before it runs, letting a team test thousands of protocol variations against modelled populations, which targets the most expensive failure in drug development: a study that could never have worked, discovered after three years and a great deal of money. Octozi works after the design is fixed, automating the data cleaning, reconciliation, review and reporting that determines whether a submission arrives on time, with a published controlled study behind it. They are sequential rather than alternatives. The question to press QuantHealth on is validation: ask how simulated outcomes compared with trials that subsequently ran, because a simulation that makes a marginal protocol look viable is worse than no simulation at all.
- It simulates trial outcomes before a trial runs, letting a development team test thousands of protocol variations against modelled patient populations rather than committing to one design and discovering the problem later.
- Simulation addresses the most expensive failure in drug development, which is a protocol that could not have worked, and it does so while the design is still cheap to change.
- For a sponsor deciding between arms, endpoints and inclusion criteria, the modelling is aimed at the decision rather than at the execution.
- It works the execution layer, cleaning, reconciling, reviewing and reporting trial data, which is where timelines slip after the protocol is fixed.
- The architecture pairs language models with deterministic clinical algorithms, and human in the loop is stated as an architectural commitment rather than a disclaimer.
- A published controlled study with named reviewers reports throughput results, which is unusual evidence for a company at this stage.

These are sequential rather than competing, one before the protocol is locked and the other after, so a sponsor may use both in the same programme. Simulation carries an exposure worth naming: a modelled trial outcome is only as good as the populations and assumptions behind it, and a simulation that makes a marginal protocol look viable is more dangerous than no simulation at all, so ask what validation exists comparing simulated outcomes to trials that subsequently ran. Neither vendor publishes a security attestation or pricing, and both should be asked whether one sponsor's data informs models serving another.
