標準治療が奏功しなかった進行性または転移性がん患者におけるITC-6146ROの研究

2026年11月5日 更新者：IntoCell, Inc

標準治療が奏功しなかった進行性または転移性がん患者を対象としたITC-6146ROの安全性、忍容性、薬物動態および予備的抗腫瘍効果を評価するための第1a/b相、オープンラベル、多施設共同、初回ヒト投与、用量漸増・拡張研究（複数のコホートを含む）

The study consists of Phase 1a (dose escalation) and Phase 1b (dose expansion). In Phase 1a, sequential cohorts of subjects will receive escalating doses of ITC-6146RO to determine maximum tolerated dose (MTD) and/or optimal biological dose (OBD).

In Phase 1b, the recommended phase 2 dose (RP2D) chosen from Phase 1a will be evaluated to further investigate safety, tolerability, pharmacokinetic (PK) and anti-tumor efficacy of ITC-6146RO.
