Massive data dive reveals how SMA drugs perform outside the lab
NCT ID NCT07403214
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study analyzed health records of nearly 5,000 people with spinal muscular atrophy (SMA) to see how well three approved treatments work in everyday medical practice. Researchers looked at complications, medical equipment use, and hospital visits before and after starting each therapy. The goal was to understand real-world treatment patterns and outcomes, not to test a new drug.

Inclusion criteria * Patients with ≥1 SMA diagnosis at any time (International Classification of Disease, Tenth Revision, Clinical Modification \[ICD-10-CM\] codes: G12.0, G12.1, G12.9). * Patients with ≥1 record of OA, nusinersen, or risdiplam based on relevant Healthcare Common Procedure Coding System (HCPCS) codes and National Drug Code (NDC). * Patients who received at least 2 of the 3 DMTs, with the first DMT initiated on or after 26 May 2019, when at least 2 DMTs were available. The initiation of the first DMT was defined as the index date and the first DMT was defined as the index DMT. * Patients with SMA types 1, 2, or 3. * Patients with ≥1 quarter of clinical activities within 1 year prior to the index quarter (for patients with SMA type 2 and 3 only). * Patients with ≥1 quarter of clinical activities any time after the index quarter, unless death occurred. Exclusion criteria * Patients with SMA type 4. * Patients with claims of multiple DMTs in their birth year.
