OncAdios LLC

Calibrated oncology-development judgment for AI-oncology companies — before the first major FDA interaction.

The scarce input is not the AI. It is the senior clinical-regulatory operator who knows when the AI is wrong — and has thirty years of FDA interactions to prove it.

OncAdios is independent of the asset-acquisition thesis, the model vendor, and the capital already committed. Its role is to adjudicate the oncology decision — including a disciplined no — and to remain accountable for the reasoning in the room where that decision is made.

What I Do · Oncology Drug Development Consulting

Three things, mapped to the three failure modes I expect to see at the FDA over the next twelve to eighteen months.

  • Endpoint and design strategy the FDA can actually review. I take AI-discovered targets and AI-prioritized candidates and translate them into endpoint structures, trial designs, and pre-IND positions the agency has precedent to accept. The model's prediction is not the endpoint; the endpoint is what the agency will adjudicate. Where established precedent fits, I use it. Where the science calls for a reasoned departure — accelerated approval on early response, novel surrogate endpoint, tumor-agnostic indication, external control — I propose it on terms the agency can engage with.
  • Trial designs that enroll. I pressure-test inclusion/exclusion logic, referral patterns, line-of-therapy windows, and combination-regimen practicality against what community oncologists will actually prescribe — before the protocol is locked. In AI-originated programs, a recurrent planning risk is confusing a computationally defined target population with one that can actually be identified, recruited, and treated at the intended sites. That gap is avoidable, and it is cheapest to close early.
  • Regulatory translation, not regulatory engineering. Serious AI/bio teams already have provenance, validation, and drift discipline. The failure mode is rarely missing engineering. The failure is that the engineering has not been translated into the language and format a CDER review division will accept, at the documentation tier the model's context of use requires. That translation is the work.

What Calibration Means in Practice

Calibration is the accuracy of confidence, not the volume of opinion.

In an AI-oncology program, calibration is the ability to look at a model's prediction, an analyst's deck, or an enthusiastic founder slide and tell — with reasons — what is true, what is conditionally true, and what will not survive a pre-IND meeting.

Calibration also asks whether the outcome being optimized is the outcome that matters. Meeting a primary endpoint, obtaining approval, achieving adoption in practice, and delivering meaningful patient benefit are different claims. OncAdios states which claim the evidence supports and refuses to promote one into another.

It also tests transportability. Evidence from one tumor type, modality, development stage, population, geography, or care setting is not assumed to carry into another. Where the bridge is weak, the limitation and the next evidence needed are part of the recommendation.

Every claim of consequence in an OncAdios deliverable is retrieved, source-tiered, and externally cited. Every recommendation surfaces the reasoning trail, the strongest counterevidence, and the conditions under which the recommendation would change. This is not a process — it is the calibration discipline that makes the recommendation auditable.

Calibration also means knowing when the right path is not the path the published guidance describes. Some of the most consequential oncology approvals — accelerated approvals built on early response data, tumor-agnostic labels, novel surrogate endpoints validated under unmet need — came from sponsors who engaged the agency in territory the agency itself acknowledged was less well understood, and who built the evidentiary package that made the new path defensible. Fitting inside the guidance is often correct. Proposing beyond it, in dialogue with the agency, is sometimes correct. Telling the two apart is the work.

When the evidence does not support a recommendation, OncAdios refuses to make one. Refusal is part of the output, not the absence of one.

OncAdios is itself an AI-augmented practice. AI is the leverage layer — used in retrieval, drafting, source-tiering, adversarial review, and pattern recognition across decades of regulatory precedent — under senior clinical-regulatory judgment and the operating standard linked below. The point is not that AI is fast. It is that the calibration system above is how AI gets used safely when the stakes are this high. The operating standard →

Where to Start · Two Front Doors

Two fixed-scope engagements. Two different questions.

Both run on a fixed clock for a fixed fee, and both stand on their own. The difference is the decision you are facing — and if you are not sure which you need, the fit call sorts it.

The Sprint reads whether your development story survives the room it is about to enter. The Read reads what your program has actually learned, and whether the next dollar is aimed correctly — a question that does not change with jurisdiction, which is why the Read travels wherever the asset is being developed. Both are the paid front door to the engagement ladder below.

Engagement Structures

Three structures, in descending order of typical availability.

The Calibration Sprint and the FIH Diligence Read are the fixed-scope entry points. These are the deeper commitments they convert into where the work warrants — a program need, not a default.

Who I Work With

You and I will be a fit if:

  • Your company is pre-IND or in Phase I, with a Series A or B closed in the last 18 months.
  • Your founding team is strong on computation and science, and already sees clinical-regulatory judgment as the next seat to fill — not the last.
  • The decisions in front of you in the next 90 to 180 days are real, and your program turns on them: endpoint strategy, trial design, FDA interactions, indication choice.
  • Where the work becomes ongoing, you are open to an equity-anchored structure with real ownership and direct accountability — not a name-on-deck advisory retainer.
  • Or you are an investor, board member, or family office evaluating someone else's oncology program — before a round, a partnership, or a disciplined no — and the question is whether their development story is calibrated.

What I decline is the retainer — the name on the deck, the board-call contract, the open-ended claim on the calendar that consumes optionality and produces nothing a more junior advisor could not. Fixed-scope work is a different instrument: the Calibration Sprint is a fixed fee for one defined decision and an artifact that stands on its own, and it ends. Where the work becomes ongoing, the shape is a small number of companies, deep involvement, real ownership, and accountability for the outcomes that determine whether the molecule lives or dies.

What the First 90 Days Look Like

A four-phase, twelve-week operating arc.

Each phase produces a specific artifact and retires a specific decision. The phases are not rigid — if the science, the data, or the agency forces a reordering, the phases reorder. The deliverables and the retired decisions do not.

Weeks 1–2

Diagnostic

Artifact

One-page Calibration Map: what is known, what is conditionally true, what is asserted but unsupported, and which of the next 8–12 decisions carry the highest regulatory consequence.

Decision retired

Scope of the engagement.

Weeks 3–5

Endpoint & Indication

Artifact

Three linked memos — Endpoint Strategy, Indication and Population Analysis, Pre-IND Target Statement. Output of an expansive-then-decisive arc.

Decision retired

What we take to the agency, and in what population.

Weeks 6–9

Trial Design & FDA Plan

Artifact

Trial-design package + pre-IND briefing-book outline + anticipated reviewer Q&A on both the standard path and the reasoned-departure path.

Decision retired

Trial design submitted for pre-IND.

Weeks 10–12

Translation & Handoff

Artifact

Strategic Theme one-pager (the artifact that travels) + regulatory translation package + next-stage CMO recommendation.

Decision retired

Post-90-day operating model.

Two variants are maintained, one for each kind of company that benefits from this work:

  • Biotech-shaped AI-oncology companies — the canonical case. Program-owners running their own programs toward an IND under their own name. The work shows up at the agency–sponsor interface.
  • AI-platform companies selling into pharma — the parallel arc. Agency-facing work becomes partner-facing work; the platform validates its capabilities so partners can defend the platform's role in their submissions.

Both share the same calibration discipline and the same expansive-then-decisive arc inside Phase 2.

An AI-native developer that acquires or licenses and sponsors its own assets follows the biotech-shaped path for those programs. If the same company also sells capabilities to partners, the partner-facing work follows the platform-shaped path. A hybrid company may require both interfaces.

For the biotech-shaped path, the first hard test is usually the pre-IND meeting: what an oncology pre-IND meeting actually decides — why the package does most of the work, how to spend a limited number of questions, and why the agency's advice is not permission to dose patients.

The Standard

Behind every OncAdios deliverable is a working calibration system, not a marketing claim.

A Citation-Required Output Contract enforces refuse-or-cite by default. An internal benchmark audits agent outputs against physician-validated rubrics. An AI Agent Operating Charter defines what data is processed in which channel, with strict confidentiality discipline for pre-competitive and identifying client material. Every recommendation of consequence surfaces, alongside the conclusion, the sources used, the alternatives considered, the strongest counterevidence, and the conditions under which the conclusion would change.

When you ask "how do you know this is right?" — the answer is a working system, not a policy document. This standard is what makes a confidence claim defensible — both when it agrees with established guidance and when it proposes to move beyond it.
