Clinical trial recruitment

Clinical trial recruitment is the process of identifying eligible patients, reaching them inside a clinical window, confirming interest and eligibility, and coordinating the next site or navigator step. Matching finds who qualifies. Recruitment is the conversation that turns a match into a consented, scheduled participant. In oncology, that conversation is where most eligible adults are lost.

What clinical trial recruitment is

Clinical trial recruitment is the operational work after a match exists: first contact, barrier discovery, protocol pre-screening, consent capture, and handoff to a site or navigator. Identification systems can score thousands of records. Recruitment is whether a person is actually reached, in their language, before the window closes.

US adult cancer trial enrollment has sat near 3% to 5% for years. The bottleneck is not only eligibility. It is fragmented data, limited coordinator capacity, and missed outreach. An eligible patient cannot enroll in a trial they never hear about.

Rivvi is the engagement layer for that conversation. Matching engines, including Massive Bio's, decide who and why. Rivvi runs first contact, pre-screening questions, and status write-back across voice, text, and web chat, with adverse-event routing on every conversation and clinical judgment left with clinicians.

Clinical trial recruitment, answered

How is recruitment different from matching?
Matching scores eligibility from consented clinical and biomarker data. Recruitment is the governed outreach that turns each match into a reached, screened, coordinated participant. One without the other leaves eligible patients uncontacted.
Why do so few adults with cancer enroll in trials?
An estimated 3% to 5% of US adults with cancer enroll in therapeutic trials. The gap is driven by fragmented records, complex eligibility, limited workforce, and missed chances to reach patients inside a narrow clinical window — not by a shortage of people who would qualify.
How does Rivvi run trial recruitment?
Rivvi works the candidate list: first-contact outreach, protocol pre-screening, scheduling, and write-back to the hub or CRM. Qualified participants route to the site. People who are not ready stay warm. Live today with Massive Bio across oncology programs in 8 countries.
