詳細な説明
これは、真性多血症患者に 1 日 1 回経口投与されたボメデムスタットの安全性、有効性、薬物動態および薬力学を評価する第 2 相多施設非盲検試験です。
患者は 36 週間の投薬を受け、その後追加の治療を受けることができます。
患者は、臨床徴候および症状の頻繁なモニタリングと安全検査室によって、両方の有害事象について研究全体を通して綿密に追跡されます。 有効性と薬力学的効果は、末梢血の頻繁な血液学的評価によって綿密に監視されます。 標準的な施設のガイドラインに従って、必要に応じて、投与中、輸血または瀉血を行うことができます。
安全性を確保するために、安全性諮問委員会は、安全性パラメーターと薬力学的マーカーの定期的なレビューを実施します。
