For most emerging biotechs, the CRO search should begin roughly six to nine months before the target date for the first participant, and earlier for a multinational or operationally complex study. That window allows about twelve weeks for a structured selection, several more weeks for contracting, and the three to six months a CRO typically needs to move from award to the first activated site. Start later, and the calendar begins making decisions that belong to you.
Why does the timing of a CRO search matter so much?
Time pressure changes how sponsors choose. When a board milestone is fixed and the first-patient date is close, the field narrows to whichever CROs can respond quickly, comparisons become shallow, and contract terms are accepted rather than negotiated. Over more than 25 years in this industry, I have watched capable leadership teams sign with a CRO they would not have chosen with six more weeks, simply because the alternative was missing a financing milestone. The decision may still turn out well, but it was made under conditions no one would design on purpose.
What needs to be in place before you start?
You do not need a final protocol to begin, but you do need enough definition for every CRO to price the same study. Before the first conversation with a CRO, aim to have:
A protocol synopsis with the design, population, primary endpoint, and schedule of assessments in draft
A realistic target for the first participant and for the key readout
Working assumptions for countries, number of sites, and enrollment
Funding visibility for the study, even if a financing round is still closing
A named internal owner for the selection and a small group of decision makers
An initial view of what you will keep in-house and what you will outsource
How long does a structured CRO selection take?
A well-run selection moves through defining requirements, narrowing the field, running the bid, deciding on the award, and preparing the contract. The ABRA PROOF™ Method is designed to be contract-ready by the end of Week 12, with each stage signed off by the sponsor before the next one begins. The contracting timeline may be extended when the master services agreement and the first work order are negotiated from scratch, which is common for a company's first CRO relationship. Fortify the Start carries you through that negotiation.
How do you work backward from first patient?
Take a sponsor targeting a first participant on 1 June. If startup from award to first site activation runs approximately four to five months for that study, the contract needs to be executed by mid-January. Working back another twelve weeks for selection puts the start of the search in late September, before the holidays compress everyone's availability. Add regulatory and drug supply milestones to the same plan, because a CRO cannot activate a site faster than the investigational product can arrive.
What if your financing has not closed yet?
You can still begin. The early stages, defining requirements and identifying the right CROs to invite, cost relatively little and save weeks later. Be candid with CROs about where financing stands, ask for proposals that remain valid for a defined period, and plan the award decision to follow closely behind the close. If startup work needs to begin before the full contract is signed, a carefully scoped letter of intent can bridge the gap.
What are the signs you have started too late?
The bid window has been shortened to two weeks or less
Only one or two CROs can commit staff within your timeline
You are considering an award without a bid defense meeting
The startup timeline in every proposal already misses your first-patient date
Contract negotiation is running in parallel with site activation
Any one of these is manageable. Several together usually mean the timeline, the scope, or the milestone itself needs an honest second look with your board.
