Onasemnogene abeparvovec, a one-time intravenous gene replacement therapy, and nusinersen, an antisense oligonucleotide that requires ongoing intrathecal administration, have been evaluated as treatments for spinal muscular atrophy (SMA) type 1 in separate Phase III trials, but no head-to-head comparison studies have been conducted. Onasemnogene abeparvovec was compared with nusinersen using a matching-adjusted indirect comparison (MAIC) to estimate the treatment effect of onasemnogene abeparvovec relative to nusinersen for the treatment of symptomatic patients with SMA type 1 for up to 24 months of follow-up. ⋯ Despite limitations of the current MAIC analysis (mainly a small sample size for statistical testing, even for the pooled onasemnogene abeparvovec trials, and potential differences in prognostic and predictive factors between studies), the relative treatment effects in EFS, OS, and motor milestone achievement indicate that onasemnogene abeparvovec may offer continued benefit compared with nusinersen through 24 months of follow-up.

Randomized Controlled Trial
Clinical development and evaluation of a VEGF-D assay in plasma from patients with metastatic colorectal cancer in the RAISE study.
Vascular endothelial growth factor (VEGF)-D was identified as a potential predictive biomarker for ramucirumab efficacy in second-line metastatic colorectal cancer using a research use only (RUO) assay. We describe results with a new assay for detecting VEGF-D in human plasma. ⋯ In patients with high VEGF-D, ramucirumab demonstrated a greater improvement in OS and PFS vs placebo; however, baseline VEGF-D level was not predictive of ramucirumab OS benefit using VEGF-D assay for IUO. The RAISE intent-to-treat results remain valid.

This study estimated the comparative efficacy of ciltacabtagene autoleucel (cilta-cel) versus the approved idecabtagene vicleucel (ide-cel) dose range of 300-460 × 106 CAR-positive T-cells for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) who were previously treated with a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody (i.e. triple-class exposed) using matching-adjusted indirect treatment comparisons (MAICs). ⋯ These analyses demonstrate improved efficacy with cilta-cel versus ide-cel for all outcomes, highlighting its therapeutic potential in patients with triple-class exposed RRMM.

Aromatic l-amino acid decarboxylase (AADC) deficiency is a rare neurological condition, associated with a wide range of symptoms and functional issues, such as profound motor impairment and learning disability. Most individuals with AADC deficiency are completely dependent on their caregivers. This study explored the impact of caring for an individual with AADC deficiency. ⋯ This is the first qualitative study to report on the experience of caring for an individual with AADC deficiency. Caregivers reported that caring had a substantial multifaceted impact on their lives. These findings highlight the importance of considering the caregiver experience when evaluating the burden of AADC deficiency.

To describe the effectiveness of secukinumab in the treatment of psoriatic arthritis (PsA) and associated physician satisfaction with secukinumab treatment, in routine clinical practice across five European countries. ⋯ Physicians were satisfied with the ability of secukinumab to control disease and it was effective in the treatment of PsA patients in routine clinical settings.
