Étude de l'ITC-6146RO chez des patients atteints d'un cancer avancé ou métastatique n'ayant pas répondu au traitement standard

2 novembre 2026 mis à jour par: IntoCell, Inc

Une étude de phase 1a/b, ouverte, multicentrique, première administration chez l’humain, d’escalade/expansion de dose avec plusieurs cohortes pour évaluer l’innocuité, la tolérabilité, la pharmacocinétique et l’efficacité antitumorale préliminaire de l’ITC-6146RO chez des patients atteints d’un cancer avancé ou métastatique ayant échoué à la thérapie standard

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.
