Leal Health
Leal Health (formerly TrialJectory) is an AI-powered treatment decision-support platform that gives cancer patients and their oncologists an unbiased, single point of access to FDA-approved therapies and clinical trials matched to a patient's exact diagnosis. Founded in 2017 and headquartered in New York, the company built a patented, generative-AI engine that reads thousands of trials and treatment options, then matches patients in a roughly two-minute intake. It has facilitated millions of treatment matches across 22+ cancer types, is free for patients and clinicians, and earns revenue from biopharma partners and health plans. In February 2026 Leal Health was acquired by Nexus Precision Health.
