Indication
- Indicated for treatment of the polyneuropathy of hereditary transthyretin-mediated amyloidosis in adults.
Summary
- Inotersen (Tegsedi) is indicated for the treatment of polyneuropathy in adults with hereditary transthyretin-mediated amyloidosis.
- A total of 5 systematic reviews and meta-analyses were reviewed, providing insights into the effectiveness and safety profile of Inotersen (Tegsedi).
- The drug has shown significant benefit in high-quality randomized controlled trials for TTR-related amyloid polyneuropathy, as highlighted by one review.
- However, another study found that an indirect comparison or network meta-analysis between Inotersen (Tegsedi), tafamidis, and patisiran was not feasible due to differences in trial designs, baseline population characteristics, outcome definitions and baseline risk across their pivotal trials.
- One review noted conflicting results on cardiac imaging parameters with Inotersen (Tegsedi) use while another pointed out a potential increase in mortality rate compared to placebo along with more dropouts due to adverse events during its clinical trial.
- Despite these concerns raised about its safety profile relative to other treatments like tafamidis or patisiran which have also been approved for ATTR-PN patients; it's important that clinicians consider individual patient characteristics when making prescribing decisions given observed cross-trial heterogeneity among these drugs' studies according to one review.
