The company says it is backed by a Series A round and NIH and NCI SBIR funding. In fiscal year 2026 the National Cancer Institute funded its SBIR project on reducing febrile neutropenia in people treated with chemotherapy with PointCheck (5R44CA228920-06, USD 991,877).","asOf":"2026-11-04","links":[{"label":"Official website","url":"https://leuko.com/"},{"label":"NIH RePORTER: 5R44CA228920-06","url":"https://reporter.nih.gov/project-details/11364218"}],"tags":[],"related":[],"cancers":[],"sections":["supportive-care","devices"],"technologies":["g-csf-growth-factors"],"targets":[],"drugs":["pointcheck"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Read on leuko.com and the NIH RePORTER record on 4 November 2026.
