ダノン病男性患者におけるRP-A501の多施設非盲検遺伝子治療研究
ダノン病の遺伝子治療:ダノン病の男性患者におけるヒトLAMP2アイソフォームB導入遺伝子(RP-A501; AAV9.LAMP2B)を含むアデノ随伴ウイルス血清型9(rAAV9)ベクターの静脈内投与の有効性と安全性を評価する第2相研究
This is a single arm Phase 2 trial to evaluate the efficacy and safety of RP-A501, a recombinant adeno-associated virus serotype 9 (rAAV9) vector containing the human lysosome-associated membrane protein 2 isoform B (LAMP2B) transgene, in male patients with Danon disease.
調査の概要
詳細な説明
RP-A501-0123 is a Phase 2 global, multi-center, single arm, open-label, single dose trial in males with Danon disease. The study is designed to assess the efficacy and safety of a single intravenous dose of RP-A501 in treating the cardiomyopathy associated with Danon disease.
RP-A501-0123 will enroll subjects ≥ 8 years of age with a pathogenic or likely pathogenic LAMP2 variant. The trial will include a total of 5 years of follow-up after administration of RP-A501.

実験的:RP-A501
A single intravenous infusion of RP-A501 in cohorts of subjects with a confirmed diagnosis of Danon disease. |
RP-A501 is a gene therapy product consisting of an rAAV9 capsid containing the human LAMP2B transgene which will be administered as a single IV infusion. Dose of RP-A501: Cohorts 1, 2 & 3 = 6.7 x10^13 genome copies (GC)/kg; Cohort 4 = 3.8 x10^13 GC/kg. An immunomodulation regimen is initiated before RP-A501 administration to reduce the risk of gene therapy-related complications. The regimen includes rituximab or a biosimilar, administered in two doses for Cohorts 1-3 and three doses for Cohort 4, along with sirolimus and corticosteroids. Pegcetacoplan was incorporated into the immunomodulation regimen for Cohort 3 but excluded in Cohort 4. |
