2026年5月11日 更新者:Merck Sharp & Dohme LLC

進行性固形腫瘍の参加者におけるMK-1200の安全性と有効性を評価するための第1/2相非盲検試験

この研究の目的は、進行性/転移性の胃/胃食道接合部(GEJ)がん、食道がん、胆道がん、膵管腺がんの治療を受けたことがある、または耐性がなかった参加者におけるMK-1200単独療法の有効性と安全性を評価することです。から、臨床上の利益をもたらすことが知られているすべての治療法。 研究のパート 1 は、最大耐用量 (MTD) を決定するための用量漸増です。 パート 2 では、2 つの異なる用量での MK-1200 の安全性と有効性を評価します。
