Amavita Research vs. Velocity Clinical Research: which clinical trial site fits your study?
Sponsors comparing Amavita Research with Velocity Clinical Research are usually deciding between a single deeply specialized cardiovascular site and one of the world's largest integrated site networks. Both models exist for good reasons; the question is which fits the protocol in front of you.
Amavita Research is a clinical trial site and PET imaging trial partner in North Miami Beach, anchored by a single dedicated cardiovascular site. The senior PI is U.S. TAVR pioneer Dr. William W. O'Neill, National PI on Edwards PARTNER, Protect II, and Protect IV. Every active study is cardiovascular, the affiliated Advanced Cardiovascular of Miami ASC supports interventional procedures on site, and processes are IAOCR GCSA-certified, valid through February 28, 2027.
Velocity Clinical Research is among the largest integrated clinical site organizations in the world, with roughly 80 sites across the U.S. and Europe, more than 220 principal investigators, and a patient database exceeding one million. It is multi-specialty by design. For sponsors that need geographic spread across many sites under a single contract, centralized operations, and database-driven recruitment at scale, that footprint is genuinely powerful.
The trade-off is depth at any one address. A network optimizes horizontally: portfolio breadth, standardized operations, and single-contract multi-site execution. A specialist site optimizes vertically: every operational dollar goes into cardiovascular research at one location - PI continuity, cardiovascular-only SOPs, and an enrollment funnel fed by an active cardiology practice.
Amavita's economics reflect that focus. There is no network overhead or MSO carve-out allocated to the protocol budget, and an anonymized 41-day contract-to-first-patient-in metric reflects what a single accountable site can do. The Miami patient population supports FDA Diversity Action Plan targets natively, and cardiac PET and radiopharmaceutical trial capability covers the emerging CV imaging-tracer pipeline.
The right model depends on the program. If the trial is multi-site by design and needs national footprint, Velocity fits. If the program needs a single deeply specialized cardiovascular site in South Florida that can move fast with named-PI accountability, Amavita fits - and many sponsors use Amavita as their lead cardiovascular site alongside network sites elsewhere.
Side-by-side: operating model
Educational summary. We describe the typical multi-site research network model and do not make claims about any specific institution's current operations.
| Dimension | Amavita Research | Velocity (typical) |
|---|---|---|
| Site type | Single dedicated cardiovascular site; PET imaging trial partner across therapeutic areas | Integrated multi-site network (~80 sites, U.S. + Europe) |
| Cardiovascular focus depth | Miami site 100% cardiovascular; PET imaging partnerships in oncology and neurology | Multi-specialty; cardiovascular is one of many areas |
| Senior PI profile | TAVR pioneer Dr. William W. O'Neill; National PI on Edwards PARTNER, Protect II, Protect IV | 220+ PIs across therapeutic areas |
| Contracting model | Single site, no network overhead | Single contract covering many sites; network operations layer |
| Patient sourcing | Active cardiology practice flow + diverse Miami population | 1M+ patient database + centralized recruitment |
| Startup speed | 41-day contract-to-first-patient-in (anonymized program metric) | Network-standardized activation at scale |
| Best fit | Single-site cardiovascular depth with PI accountability | Multi-site programs needing national footprint |
Frequently asked questions
When does a large site network make more sense?
When the trial is multi-site by design, needs geographic spread across many U.S. or European sites, and benefits from single-contract execution and database-driven recruitment.
What does a single specialist site offer that a network site does not?
Named-PI accountability from selection through close-out, a 100% cardiovascular operational stack, no network overhead in the budget, and an on-site cardiovascular ASC.
Can Amavita work alongside a network in the same program?
Yes. Sponsors commonly place Amavita as their lead South Florida cardiovascular site while using network sites for geographic coverage elsewhere.
How does cost structure differ?
Independent sites carry no MSO carve-out or network overhead allocation. Network pricing reflects centralized operations spread across the portfolio.
