ENERGY 2:评估 INZ-701 对 ENPP1 缺乏症婴儿的疗效与安全性
ENERGY 2研究:一项评估INZ-701在婴儿期外核苷酸焦磷酸酶/磷酸二酯酶1(ENPP1)缺乏症中疗效和安全性的开放标签3期研究
The primary purpose of ENERGY 2 (Study INZ701-105) is to assess the efficacy and safety of INZ-701 in infants with ENPP1 Deficiency.
研究概览
详细说明
ENPP1 Deficiency is an ultra-rare genetic disorder in which inactivating mutations in the ENPP1 gene lead to a deficiency in the ENPP1 enzyme.
ENERGY 2 (Study INZ701-105) is a multicenter, single-arm, open-label Phase 3 study to assess the efficacy and safety of INZ-701 in infants with ENPP1 Deficiency.
The study will consist of a Screening Period of up to 60 days, a Treatment Period of 52 weeks, a 52-week Extension Period, and an End of Treatment (EOT) Visit 30 days after the last dose of INZ-701.

实验性的:INZ-701
Participants receive INZ-701 (rhENPP1-Fc) administered by subcutaneous injection once weekly at the protocol-specified dose. The visit final volume to administer (mL) is determined using protocol-defined parameters. |
Recombinant fusion protein that contains the extracellular domains of human ENPP1 coupled with an Fc fragment from an immunoglobulin gamma-1 (IgG1) antibody.
