How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The size was built upward from treated patient volumes and realised prices. For approved products, the build starts from diagnosed recurrent Clostridioides difficile infection cases, the share treated with a microbiome product, courses per patient and net price per course. For pipeline and special-access supply, it uses named-patient and hospital-exemption volumes, collaboration and licensing receipts, and prebiotic therapeutic sales. The build was then checked against revenue disclosed in company filings for suppliers with marketed products. Where the two disagreed, the bottom-up assumption was corrected, usually treatment rate or net price, and the disclosed figure was not averaged in. Regional and segment values were allocated from the same unit and price inputs.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary conversations target the roles that decide whether and how these products are used: gastroenterologists and infectious disease physicians, hospital pharmacy and formulary committee members, specialty pharmacy managers, payer medical directors, clinical development and regulatory leads at developers, and contract manufacturing executives with anaerobic fermentation capacity. Sampling emphasises North America, where the first approvals and the deepest reimbursement exist, and Europe, where national pathways and hospital exemption routes differ by country. Asia Pacific is covered through Japan, South Korea and China, where regulatory expectations and local clinical programmes are still taking shape.
Desk research rests on the US Food and Drug Administration biologics approval and advisory committee records, the European Medicines Agency public assessment reports and the EU Clinical Trials Register, and ClinicalTrials.gov for pipeline stage and enrolment. Disease burden comes from the US Centers for Disease Control and Prevention Clostridioides difficile surveillance reports and the European Centre for Disease Prevention and Control antimicrobial resistance data. Supplier revenue and cost inputs come from annual reports and Securities and Exchange Commission filings. Peer-reviewed trial publications and patent registers inform strain, route and formulation detail.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from patient eligibility, treatment rate and net price by indication, with each pipeline programme weighted by its stage and the typical rate at which programmes in that stage reach approval. Adoption curves for recurrent Clostridioides difficile infection are extended to inflammatory bowel disease, metabolic and oncology use as trial readouts arrive. Pricing is held near current levels, with modest erosion as manufacturing scales. Early launch effects are normalised so that stocking in the launch quarters does not inflate the base. For the forecast to hold, some late-stage programmes must succeed outside infection, payers must keep reimbursing courses, and supply must scale without quality failures.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Outputs were back-tested against recorded growth in the historical period, in particular the step up that followed the first regulatory approvals, and implied growth rates were compared year by year for breaks that the underlying drivers do not explain. Segment shifts were reviewed with clinical and commercial experts, and the driver and restraint contributions were reconciled to the forecast-period revenue change. Sensitivities were run on treatment rate, net price per course and the approval timing of the largest late-stage programmes, and the bull and bear cases reflect the range those tests produced.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
The estimate is firmest for approved live biotherapeutic and fecal microbiota products in recurrent Clostridioides difficile infection, where volumes, prices and company disclosures can be cross-checked. It is weaker for revenue attributed to pipeline stages, special-access supply, and the bacteriophage and engineered categories, where reporting is thin and timing depends on trial outcomes. Country detail outside the United States and the largest European markets is less certain. A single late-stage failure or a change in reimbursement could force a revision, and a band of one fifth either side of the base case is reasonable for the later forecast years.
