S 4472 United States Senate · 119th Congress

Accelerating Access to Critical Therapies for ALS Reauthorization Act of 2026

This bill extends the funding authorization for the Accelerating Access to Critical Therapies for ALS Act from 2026 to 2031, ensuring continued financial support for research into treatments for amyotrophic lateral sclerosis. It requires the Food and Drug Administration to review clinical trial data more rigorously by assessing patient enrollment numbers and requesting interim results from drug manufacturers before renewing research grants. Additionally, the legislation clarifies that clinical trials in phase 3 include combined phase 2/3 studies and planned trials that have not yet started enrolling participants. The bill also mandates the FDA to publish a report within a year of enactment detailing its progress on rare neurodegenerative disease action plans and how it coordinates with broader disease communities. Finally, it adjusts the timeline for a Government Accountability Office report to cover a five-year period instead of four.

What changed between versions

Introduced in Senate Engrossed in Senate · 8 edits · Aug 4, 2026
MODERATE
The Senate Engrossed version of S 4472 substantially expands oversight and accountability requirements for the ALS expanded access grant program, adds a new HHS effectiveness report to Congress, converts the FDA action plan from a one-time deliverable into a recurring five-year cycle with barrier analysis, and tightens grant renewal criteria by requiring enrollment, safety, and efficacy data assessments. A new technical amendments section corrects typos in the underlying statute.
TIMELINE

The reauthorization window was clarified from simply extending to 2031 to explicitly covering fiscal years 2027 through 2031 (replacing 2022 through 2026).

The FDA action plan report was changed from a one-time requirement to a recurring obligation: an initial report within one year of enactment and updated reports every five years thereafter, with each subsequent plan required to describe previous actions taken, planned actions, and barriers with resource estimates.

The GAO report deadline was changed from four years after enactment of the original Act to five years after enactment of this Reauthorization Act of 2026, and the section was restructured into separate GAO and HHS report subsections.

REQUIREMENT

Grant applications must now include a description of how data generated through the expanded access grant will be used to support ALS research or development, and an assurance that the entity will promptly report available safety data from any ongoing clinical trial of the investigational drug.

For grant renewals, the Secretary must now request from the sponsor and assess enrollment, safety, and any available efficacy data of the drug related to ALS prevention, diagnosis, mitigation, treatment, or cure.

DEFINITION

The definition of phase 3 clinical trial was moved into the statutory definitions section and a new requirement was added that a phase 3 trial must begin enrollment within a timeframe determined by the Secretary through grant terms and conditions.

ENFORCEMENT

A new HHS report is required within four years of enactment, in which the Secretary of Health and Human Services must submit to the Senate HELP Committee and House Energy and Commerce Committee an assessment of the effectiveness of activities under sections 2, 3, and 5, with recommendations for improvement.

TECHNICAL

A new Section 6 makes two technical corrections: fixes the typo 'amytrophic' to 'amyotrophic' in Section 3(a) and removes the stray word 'rational' from Section 3(b)(3)(A)(iii).
