Expanded access programs (EAPs) successfully enrolled patients with amyotrophic lateral sclerosis (ALS) who were ineligible for clinical trials. These multicenter EAPs provided access to investigational products, demonstrating a viable pathway for ALS treatment access.
Area of Science:
- Neurology
- Clinical Trials
- Drug Development
Background:
- Expanded Access (EA) provides FDA-regulated access to investigational products (IPs) for serious diseases.
- Patients ineligible for clinical trials often lack access to novel therapeutics.
- Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease with limited treatment options.
Purpose of the Study:
- To describe the design and operations of a multicenter, multidrug Expanded Access Program (EAP) for ALS.
- To assess the feasibility of enrolling patients ineligible for clinical trials into EAPs.
- To provide access to investigational products (IPs) for ALS patients through a coordinated program.
Main Methods:
- Established a central coordination center for program design and execution.
- Developed templated documents and processes for streamlined study design and regulatory submissions.
- Implemented three Expanded Access Protocols (EAPs) linked to the HEALEY ALS Platform Trial, enrolling patients with advanced or long-standing ALS.
Main Results:
- Screened 85 participants across three EAPs with a low screen failure rate (3.5%).
- Successfully enrolled participants, informing the duration of the platform trial regimens.
- The verdiperstat EAP concluded with a mean participation of 5.8 months; CNM-Au8 and pridopidine EAPs are ongoing.
Conclusions:
- Multicenter Expanded Access Programs (EAPs) can be successfully implemented in parallel with clinical trials.
- These programs effectively enroll patients with amyotrophic lateral sclerosis (ALS) who do not meet clinical trial eligibility criteria.
- EA programs offer a crucial pathway for accessing investigational treatments for ALS patients outside of traditional clinical trials.
