Why one benchmark number is dangerous

Phase 1 cost depends on cohort count, healthy-volunteer versus patient population, inpatient or outpatient requirements, PK/PD sampling, sentinel dosing, imaging, central labs, manufacturing support, monitoring, data, safety oversight, number of sites and geography. A single blended industry average can hide the variables that actually control your budget.

Start with the pieces you can price

Separate patient-level cost, screen failures, site startup, recurring site fees, CRO scope, central vendors, travel/shipping and any special procedures. If a category is unknown, keep it UNKNOWN rather than silently treating it as zero.

The better question

Instead of asking only 'what will Phase 1 cost?', ask 'what is the cheapest credible design that can answer the next management question?' That is Cost-to-Truth.

Questions people actually ask

FAQ

Is a Phase 1 trial always cheaper than Phase 2?

Not necessarily. Intensive sampling, inpatient stays, specialist procedures or rare-patient recruitment can make an early study expensive.

Should I use an industry average?

Use it only as orientation. A protocol-specific budget should be built from actual assumptions and quotes.

Compare actual capable sites, startup path, recruitment, incentives, logistics and evidence value. How Many Sites Does a Clinical Trial Need?More sites can increase recruitment capacity, but every site adds startup, monitoring and management burden. The answer depends on credible enrollment per site.
