研究概览
简要总结
The purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in participants with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran subcutaneous (SC) injection once every 3 months (q3M) or the reference comparator patisiran intravenous (IV) injection once every 3 weeks (q3w) during the 18 month Treatment Period. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints during the 18 Month Treatment Period. Following the 18 Month Treatment Period, all participants will be randomized to receive vutrisiran 50 mg SC injection once every 6 months (q6M) or vutrisiran 25 mg q3M in the Randomized Treatment Extension (RTE) Period. Upon implementation of Amendment 6, participants receiving vutrisiran SC 50 mg q6M will transition to vutrisiran SC 25 mg q3M at their next scheduled dosing.

研究组 & 干预措施
Vutrisiran + Vutrisiran (HELIOS-A)
Participants will receive vutrisiran 25 mg subcutaneous (SC) injection once every 3 months (q3M) for 18 months during the Treatment Period followed by vutrisiran 50 mg SC injection once every 6 months (q6M) or vutrisiran 25 mg q3M during the Randomized Treatment Extension (RTE) Period. Upon implementation of Amendment 6, participants receiving vutrisiran SC 50 mg q6M will transition to vutrisiran SC 25 mg q3M at their next scheduled dosing.
干预措施: Vutrisiran (Drug)
Patisiran + Vutrisiran (HELIOS-A)
Participants will receive patisiran 0.3 mg/kg intravenous (IV) infusion once every 3 weeks (q3w) for 18 months during the Treatment Period followed by vutrisiran 50 mg SC injection once q6M or vutrisiran 25 mg q3M during the RTE Period. Upon implementation of Amendment 6, participants receiving vutrisiran SC 50 mg q6M will transition to vutrisiran SC 25 mg q3M at their next scheduled dosing.
干预措施: Patisiran (Drug)
Patisiran + Vutrisiran (HELIOS-A)
Participants will receive patisiran 0.3 mg/kg intravenous (IV) infusion once every 3 weeks (q3w) for 18 months during the Treatment Period followed by vutrisiran 50 mg SC injection once q6M or vutrisiran 25 mg q3M during the RTE Period. Upon implementation of Amendment 6, participants receiving vutrisiran SC 50 mg q6M will transition to vutrisiran SC 25 mg q3M at their next scheduled dosing.

结局指标
主要结局
Change From Baseline in the Modified Neurologic Impairment Score +7 (mNIS+7) at Month 9 Between the Vutrisiran Group (HELIOS-A) and the External Placebo Comparator Group [APOLLO (NCT01960348)]
时间窗: Baseline, Month 9
The mNIS+7 is a composite score that measures neurologic impairment which includes the following components: physical exam of lower limbs, upper limbs and cranial nerves to assess motor strength/weakness, electrophysiologic measurement of small and large nerve fiber function, sensory testing and postural blood pressure. The mNIS+7 is scored from 0 (no impairment) to 304 points (maximum impairment). A higher score indicates a worse outcome.
