For biotech sponsors · the Protocol Stress Test

Stress test the protocol before you commit the runway.

In biotech you don’t get a do-over on site selection. The Protocol Stress Test is the read pharma has always had before committing to a trial: how many patients actually qualify under your draft protocol, what each criterion costs, and which sites can reach them. Delivered by our team in days, in the window between registering the trial and choosing the sites.

The window

Site selection is the last cheap decision in the whole trial.

A wrong site does not announce itself at the start. It shows up as a slow ramp, then an amendment, then rescue sites at a premium, then a milestone that lands a quarter late. Every one of those costs more than the decision that caused it. The only time it is cheap to get right is the few weeks before the first site is chosen.

You are in that window right now if any of these is true:

  • 01You have registered a trial that is not recruiting yet.The protocol exists. The sites do not.
  • 02You have just closed a round, or you are about to.The investors priced the timeline. Enrollment decides whether they were right.
  • 03You have an IND, a fast track or a designation in hand.The regulator said go. The next question is where.
  • 04You are hiring your first Head of Clinical Operations.Or you are the whole clinical operations team.
The difference, in one picture

Two site lists. One makes the milestone.

Same protocol, same runway. The only difference is whether the sites were chosen on a guess or on real, counted patients.

The Protocol Stress Test

One read of your draft protocol. A plan your board can defend.

Pharma has always had this kind of intelligence before committing to a trial. Small biotech usually finds out the hard way. The Protocol Stress Test is that read: clinical trial feasibility for biotech, sized for a biotech budget and delivered by our team in days, not a feasibility cycle.

  • The counted qualifying pool. How many patients actually meet your protocol as written, counted from the real patient record, not estimated from a therapeutic-area average.
  • The patient cost of every criterion, with the what-ifs. The lines that quietly strangle the pool, what each one costs, and the modelled what-if on opening or holding each, so you see where the protocol can safely open up with the same scientific intent.
  • The ranked site list. Counted patients paired with investigators who have enrolled before, with the reasoning behind every rank and the marquee names that would have failed removed.
  • The sign-off memo. A one-page go or no-go you can put in front of your board and your investors, with the number behind it.
  • Up to two amendment re-runs. Protocols change. The stress test is re-run when yours does, up to twice over the life of the trial.
  • The award-stage deep dive. The full site, investigator and enrollment-forecast workup for the trial you actually run, if the protocol advances.

One fixed fee per protocol, quoted on the call and sized for a biotech budget. It covers the re-runs. It is the go or no-go gate before the raise, and it costs a fraction of finding out six months in.

Explore the stress test

Every criterion has a price in patients. Open one and watch the pool move.

This is the part of the stress test that changes protocols. Each line below is a draft eligibility criterion with what it costs in qualifying patients. Toggle any of them and the counted pool, the reachable sites and the verdict update. The clinical call stays yours; the count is what makes it an informed one.

Open the two low-risk criteria and see what the published program saw: nearly three times the pool, same scientific intent.

Explainable, or it is useless

Every site on the list comes with its reasons.

A site list your board cannot interrogate is a site list they will not fund. So every rank we hand back carries the same four things, in plain language: the counted patients at that institution, the number under the investigator's own care, the investigator's real enrollment record, and why the site made the list or was cut. Pick a site.

What we tell you
  • The counted qualifying pool, under the protocol as written
  • What each criterion costs, with the intent risk flagged
  • Every site ranked, with the counts, the record and the reasoning
  • The re-run, whenever the protocol changes
What we do not
  • Raw patient data, ever. It is de-identified and stays with us
  • How the model weighs the signals. The reasoning is yours; the method is ours
  • A guarantee of enrollment. We give you inputs you can defend, not a promise
  • Your protocol, to anyone. Scoped to your engagement, never pooled

The runway math

A wrong site list rarely costs a line item. It costs months.

Put in your own numbers. The slip is the part nobody budgets for: the months between the enrollment plan and what the sites actually deliver, paid for at your full burn.

Industry context: about 37% of trial sites under-enroll and 11% never enroll a patient (Tufts CSDD); 57% of protocols need at least one substantial amendment, median direct cost $141K to $535K (Tufts CSDD). Sources →

Why it holds up

Real data. Not inferred.

We can show the patients are there because we can actually see them — the whole journey, every U.S. institution, even for rare and hard-to-find populations, not a snapshot. It’s the data advantage big pharma has always had, made reachable for teams where every trial counts.

How it works with us

Three decisions the runway hinges on. One embedded team.

You do not need a feasibility department to get this right. You need a straight answer at three moments, and a team that hands it to you rather than a tool you have to run. Here is what we hand back at each one.

Decision 01 · the protocol

Lock the criteria, or open them up?

Every eligibility criterion has a price in patients, and a draft protocol can quietly strangle its own enrollment pool. Before it is locked, we show you what each line costs in qualifying patients and where the protocol can safely open up.

You get backThe stress test on the draft: a criterion-by-criterion read of the qualifying pool, before the protocol is final.
Decision 02 · the sites

Which sites do we actually activate?

A bigger eligible pool only matters if your sites can reach it. We count the qualifying patients at each candidate site and pair them with the investigator's real enrollment record, so the marquee names that would have failed come off the list before you pay to activate them.

You get backA ranked site list with counts, named investigators and the reasoning behind every rank.
Decision 03 · the board

Will it enroll?

The question your board and your investors will ask, and the one a slow ramp answers for you six months late. You walk in with a number for every site and the investigator who will deliver it, and you commit the runway to a plan you can defend.

You get backA one-page go or no-go sign-off memo, with the number behind it, for the board. Re-run if the protocol changes, and the full deep dive if it advances.
Proof

See it on a real study.

In a recent rare-disease program, reading the protocol against real patient records nearly tripled the eligible pool — then became a ranked list of the sites that could actually reach those patients, before a dollar of startup budget was committed.

Questions sponsors ask

For biotech, answered.

What is the Protocol Stress Test?

One read of your draft protocol against the real patient record: how many patients actually qualify as written, what each eligibility criterion costs in patients, and the sites and investigators that can reach them, ranked with the reasoning. It is re-run if you amend, and it becomes the full site workup when the trial advances. It is the go or no-go gate before the raise. What is in it →

Can we see it before we commit?

Yes. Book a twenty-minute preview and we walk you through the stress test on a real rare-disease program, the one in our published case study, so you see exactly what comes back. A count on your own protocol follows once we are engaged and the data is bought properly for your trial. Book the preview →

What does it cost?

One fixed fee per protocol, quoted on the call and sized for a biotech budget. It covers the re-runs if you amend. Pharma-grade intelligence at biotech pricing, and a fraction of what a slow ramp costs six months in.

We have one trial and a small team. Is this too heavy for us?

No. It is built for exactly that. You send us the protocol and we do the work; there is no software to run and nothing to staff. You get the finished answer in days: how many patients actually qualify, which sites can reach them, and why. A forward-deployed team, not a tool for a two-person clinical operations group to learn. Send us your protocol →

Can you help before the protocol is final?

Yes, and that is the best time. We measure what each eligibility criterion costs in qualifying patients, so you can see where the protocol can safely open up and where it should not move. In a recent rare-disease program that nearly tripled the qualifying pool with the same scientific intent. Read the case study →

Our CRO handles site selection. Where do you fit?

As the check before you commit. Sponsors use us to pressure-test a proposed site list against the real patient record before activation dollars are spent, and the evidence works alongside whatever CRO you run with. It is your runway; this is how you protect it.

How do you protect our protocol and data?

Your protocol and study details stay yours. Every analysis is scoped to your engagement, runs on our own sourced evidence, and is never pooled with another client’s work. You receive the outcome, a ranked site list and the reasoning, never raw patient data, and the underlying record is de-identified by design. The honest boundary →

What do we actually get back?

A ranked, defensible site list, one page per site: the site and principal investigator with contacts and startup readiness, the qualifying patient counts at the facility and under the investigator’s direct care, a measured enrollment track record, and why each site made the list and why some marquee names did not. It is the answer to the question your board will ask: will it enroll? See the deliverable →

Do you use real-world data before the protocol is locked?

Yes. The Protocol Stress Test uses real, patient-level real-world data to count how many patients would qualify under the draft criteria, so you can go ahead as written or change the protocol with the numbers in front of you.
