インドの健康な子供、青少年、成人を対象としたデング熱ワクチンの研究
インドで4~60歳の健康な被験者に皮下投与されたデング熱四価ワクチン(生弱毒化)(TDV)の安全性と免疫原性を調査するランダム化二重盲検プラセボ対照第3相試験
この研究の主な目的は、武田薬品のデング熱ワクチンを3か月以内に2回接種した場合の副作用と参加者の免疫反応について知ることです。
参加者はランダム化された治療法(ワクチンまたはプラセボ)を2回投与されます。 子供、青少年、成人は初日にワクチンまたはプラセボのいずれかを1回接種し、3か月後にワクチンまたはプラセボの2回目の接種を受けます。 研究全体を通じて最大 4 つの血液サンプルが採取されます。
研究期間中、参加者は研究クリニックを6回訪問します。
調査の概要
詳細な説明
この研究で試験されているワクチンはTDV(Live, Attenuated)と呼ばれています。 TDVはデング熱を予防するために試験されています。 この研究では、健康な参加者におけるTDVの安全性と免疫原性を評価します。
この研究には約480人の患者が登録される予定だ。 参加者は、TDV またはプラセボのいずれかを受け取るようにランダムに (コインを投げるなどの偶然により) 割り当てられます。これらは、研究中、参加者および研究者には非公開のままとなります。
- コホート 1、18 歳以上から 60 歳以下の年齢グループ: TDV
- コホート 1、18 歳以上から 60 歳以下の年齢グループ: プラセボ
- コホート 2、4 歳以上から 18 歳未満の年齢グループ: TDV
- コホート 2、4 歳以上から 18 歳未満の年齢グループ: プラセボ
この多施設共同治験はインドで実施されます。 研究全体の期間は約 9 か月です。
