En studie av ITC-6146RO hos pasienter med avansert eller metastatisk kreft som har mislyktes med standardbehandling

2. november 2026 oppdatert av: IntoCell, Inc

En fase 1a/b, åpenmerket, multisenter, først-på-mennesker, doseeskalering/ekspansjonsstudie med flere kohorter for å evaluere sikkerhet, tolerabilitet, farmakokinetikk og foreløpig anti-tumor effekt av ITC-6146RO hos pasienter med avansert eller metastatisk kreft som har sviktet på standardterapi

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.
