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 updates across voice, text, and web chat, with adverse-event routing on every conversation and clinical judgment left with clinicians.
