01 · The brief
Plain-English summaryWhat this bill actually does

The bill, the Clinical Trial Modernization Act, promotes enrollment of underrepresented populations in clinical trials by funding community outreach, training, and partnerships; creates and clarifies safe harbors in anti-kickback law for sponsor payments covering trial-related expenses and digital health tools; permits sponsor payment of patient cost-sharing under strict conditions; excludes up to $2,000 of clinical trial payments from taxable income annually; and authorizes appropriations for FY2025–2026. It includes definitions tied to NIH and FDA guidance and non-federal-liability-limiting language for other protections.

Why people may split

Liberal emphasizes equity gains and removing participation barriers.
