Inotersen, sold under the brand name Tegsedi, is a 2'-O-(2-methoxyethyl) (2'-MOE)

hereditary transthyretin-mediated amyloidosis.[6][7] The sequence is TCTTG GTTACATGAA ATCCC, where C is methylated C, and the first and third section (bases 1-5 and 16–20, separated from the middle section by spaces) are MOE-modified.[8]

The most common side effects are injection site reactions (redness, swelling, bleeding, pain, rash, and itching at the injection site), nausea, headache, tiredness, low platelet counts, and fever.[6]

Inotersen can cause serious side effects, including low platelet counts and kidney inflammation.[6] Because of these serious side effects, Inotersen is available in the United States only through a restricted program called the Tegsedi Risk Evaluation and Mitigation (REMS) Program.[6]

The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[9]

History

Inotersen was approved for medical use in the European Union in July 2018.[5]

The U.S. Food and Drug Administration (FDA) approved inotersen in October 2018.[6] The application for inotersen was granted orphan drug designation.[10]

The FDA approved inotersen based on evidence from one clinical trial (Trial 1/NCT01737398) that included 172 patients with hereditary transthyretin-mediated amyloidosis.[6] The trial was conducted at 24 sites in Australia, Europe, South America, and the United States.[6]

The benefits and side effects of inotersen were evaluated in one clinical trial that enrolled patients with hereditary transthyretin-mediated amyloidosis.[6] Patients were randomly assigned to receive inotersen or placebo by subcutaneous injection given once a week for 65 weeks.[6] During the first week of treatment, patients received three doses of treatment, followed by once weekly subcutaneous injections for 64 weeks.[6] Neither the patients nor the health care providers knew which treatment was being given until after the trial was completed.[6]
