Randomized Controlled Trial Multicenter Study
Effects of eplontersen on symptoms of autonomic neuropathy in hereditary transthyretin-mediated amyloidosis: secondary analysis from the NEURO-TTRansform trial.
The NEURO-TTRansform trial showed that after 66 weeks of treatment, eplontersen significantly reduced neuropathic impairment and improved quality of life (QoL) in patients with hereditary transthyretin-mediated amyloidosis with polyneuropathy (ATTRv-PN). In this secondary analysis from NEURO-TTRansform, autonomic impairment, and the impact of eplontersen on autonomic impairment progression was evaluated through 85 weeks in patients randomised to eplontersen (n = 144) versus external placebo (n = 60; through Week 66 from the NEURO-TTR trial). ⋯ Eplontersen demonstrated benefit across multiple measures of autonomic impairment known to progress rapidly and negatively impact QoL without treatment, without deterioration in nutritional status.

Randomized Controlled Trial
Impact of cytogenetic abnormalities on treatment outcomes in patients with amyloid light-chain amyloidosis: subanalyses from the ANDROMEDA study.
Cytogenetic abnormalities are common in patients with amyloid light-chain (AL) amyloidosis; some are associated with poorer outcomes. This post hoc analysis of ANDROMEDA evaluated the impact of certain cytogenetic abnormalities on outcomes in this patient population. ⋯ These results support the use of D-VCd as standard of care in patients with newly diagnosed AL amyloidosis regardless of cytogenetic abnormalities.

Randomized Controlled Trial
Efficacy and safety of vutrisiran for patients with hereditary transthyretin-mediated amyloidosis with polyneuropathy: a randomized clinical trial.
The study objective was to assess the effect of vutrisiran, an RNA interference therapeutic that reduces transthyretin (TTR) production, in patients with hereditary transthyretin (ATTRv) amyloidosis with polyneuropathy. ⋯ NCT03759379.

Randomized Controlled Trial Multicenter Study
Treatment with daratumumab in patients with relapsed/refractory AL amyloidosis: a multicentric retrospective study and review of the literature.
Management of patients with relapsed or refractory (R/R) AL amyloidosis is complex. Some initial reports have shown positive results with daratumumab in heavily pre-treated AL amyloidosis patients. In this retrospective multicentric study, 38 patients (mean age 64 ± 9 years) with R/R AL amyloidosis treated with daratumumab were included. ⋯ Cardiac and renal organ response rates were 37 and 59%. At 12 months, overall and progression-free survival were 59% (95%CI: 0.36-0.77) and 52% (95%CI: 0.29-0.70), respectively. Daratumumab is a safe and effective drug in the treatment of R/R AL amyloidosis and should be considered early in the course of the disease.

Randomized Controlled Trial Multicenter Study
Quality of life outcomes in APOLLO, the phase 3 trial of the RNAi therapeutic patisiran in patients with hereditary transthyretin-mediated amyloidosis.
Introduction: Hereditary transthyretin-mediated (hATTR) amyloidosis is a rare, fatal, multisystem disease leading to deteriorating quality of life (QOL). The impact of patisiran on QOL in patients with hATTR amyloidosis with polyneuropathy from the phase 3 APOLLO study (NCT01960348) is evaluated. Methods: Patients received either patisiran 0.3 mg/kg (n = 148) or placebo (n = 77) intravenously once every three weeks for 18 months. ⋯ At 18 months, patisiran improved Norfolk QOL-DN total score and three individual domains as well as COMPASS-31 total scores relative to baseline. Consistent benefits were also observed in the cardiac subpopulation. Conclusion: The benefits of patisiran across all QOL measures and the rapid deterioration observed with placebo, highlight the urgency in early treatment for patients with hATTR amyloidosis with polyneuropathy.
