Selecting a clinical trial site in Puerto Rico requires more than adding another location to a country plan. The sponsor needs to understand which investigator will oversee the protocol, how potential participants reach the site and how the required assessments fit into everyday operations.
A useful assessment connects the clinical opportunity with the actual visit pathway. The questions below help sponsors and CROs review a Puerto Rico site in enough detail to make an informed placement decision, while keeping the evaluation specific to the proposed study.
Start with investigator fit and available oversight
Match the protocol's clinical decisions and procedures to the proposed investigator's experience. Ask about the relevant indication, patient population and study demands, rather than relying only on a broad specialty label or a total trial count.
WCR's investigator directory identifies Gustavo R. Albizu-Angulo, MD, as principal investigator at its Puerto Rico location and describes a team with experience across several therapeutic areas. Use that published background as a starting point for discussion, then confirm who would be assigned to the specific protocol.
Review availability as well as qualifications. Who will review eligibility, address medical questions and oversee delegated work? How are absences covered? Which tasks need a specialist? A strong team profile is most useful when the sponsor can connect it to named responsibilities and realistic availability for the study.
Understand the patient pathway behind the estimate
Ask where potential participants would originate and how those pathways will operate. An established practice population, an outside referral and an advertising response can each be valuable, but they require different steps before clinical review and screening.
For a referral route, clarify who identifies a possible candidate, what information accompanies the referral and how missing records are obtained through the appropriate process. For a practice population, ask which protocol requirements are documented and which will remain unknown until screening.
Avoid treating a diagnosis count as an enrollment forecast. Relevant treatment history, current clinical status, willingness to participate and available visit capacity all affect the estimate. For a study spanning several locations, use shared definitions while checking the assumptions behind each location's contribution. That supports a network view without making every patient pathway appear identical.
Verify where each assessment will happen
For every protocol-required procedure, ask whether it is performed within the research site or arranged through another provider. Then confirm scheduling, qualification, documentation, result delivery and how the participant moves between appointments.
WCR's Puerto Rico location page describes clinical and laboratory workspace, specimen collection and processing, temperature-controlled storage, and coordinated access to services such as imaging and endoscopy. The page distinguishes local provider access from services confirmed physically on-site. Feasibility should establish the arrangement needed for the proposed protocol.
A coordinated service can work well when the handoff is clear. Ask who books the appointment, who provides preparation instructions, how the site receives results and what happens if the provider cannot accommodate the required visit window. Confirm the budget and agreement reflect that work rather than leaving it to an informal understanding.
Follow a specimen from collection to receipt
A laboratory equipment list answers only part of the feasibility question. Walk through the sample's full journey: collection, time-sensitive processing, storage, packaging, pickup and receipt at the destination laboratory.
Use the sponsor's actual laboratory requirements to discuss courier schedules, temperature conditions and the handling of a missed pickup. Consider the relationship between visit times and shipping availability, especially for samples that cannot wait until the following working day.
Confirm who owns shipment documentation, tracking and escalation. Ask how the team would respond to a transport disruption or equipment issue and how the sponsor would be informed. The purpose is to establish a workable process for this study, not to assume that every sample type can follow the same routine.
Plan bilingual communication across every handoff
English- and Spanish-language support should be considered across the entire participant journey. Discuss initial contact, consent materials, visit preparation, participant-reported assessments, reminder messages and questions between visits.
Ask who is responsible for required translations and how final approved versions reach the people using them. A sponsor, CRO, vendor and site may each own different parts of the process. The timeline should identify those responsibilities early enough to prevent avoidable waiting at activation.
Also review communication with outside providers. A participant may understand the research visit but receive unclear instructions for a separate procedure. The site-selection discussion should cover how those instructions are coordinated and how clinical questions return to the investigator. Materials and staff support need to fit the protocol and the participant, not simply the language selected on a form.
Check the practicality of the visit schedule
Review the longest and most frequent visits against the lives of the people being asked to attend. Travel, work, caregiving, appointment preparation and an escort requirement can affect whether a plausible candidate can participate throughout the study.
Ask the site how it discusses these demands before screening and how it handles scheduling conflicts within allowed windows. Where the sponsor provides transportation or reimbursement support, confirm the actual arrangement and how participants will receive accurate information about it.
The same review should address staff and room capacity. A location may be clinically well suited to the protocol while having limited availability at the times a particular population can attend. Resolve those constraints during selection rather than assuming that appointment demand will distribute itself evenly.
Confirm readiness and reporting before placement
Ask for a study-specific view of contracts, regulatory work, personnel training, system access, materials and external service dependencies. Define the milestone being forecast and the inputs needed to reach it.
FDA's E6(R3) Good Clinical Practice guidance emphasizes appropriate resources and clear responsibility for trial conduct. In site selection, translate that principle into evidence of who will do the work, what they need and how oversight will function. A capability statement is the beginning of that review.
Agree on a small set of useful progress measures. Records received, clinical reviews completed, screenings conducted and enrollments achieved reveal different stages. Clear definitions let the sponsor and site identify a problem early and discuss the action needed without confusing activity with outcomes.
What to include in a Puerto Rico feasibility request
A focused request helps the site provide a useful response. Include:
- The protocol or a sufficiently detailed study synopsis and target population.
- Key eligibility requirements and required treatment history.
- The expected enrollment period and proposed site contribution.
- The visit schedule, procedure needs and specimen-handling requirements.
- Language and participant-support requirements.
- Known vendor, training and startup dependencies.
Connect regional opportunity with protocol fit
WCR operates as a network serving South Florida and Puerto Rico. A coordinated approach can support shared planning while keeping the study's clinical, procedural and participant requirements visible.
To evaluate placement, use the existing submit-a-study form and identify Puerto Rico as an area of interest. The most useful next step is a protocol review that connects investigator experience, patient access and the operations required to deliver the visits.
