Sikkerhed og effektivitet af MK-1200 hos deltagere med avancerede solide tumorer

11. maj 2026 opdateret af: Merck Sharp & Dohme LLC

Et fase 1/2 åbent studie for at evaluere sikkerheden og effektiviteten af ​​MK-1200 hos deltagere med avancerede solide tumorer

Formålet med denne undersøgelse er at vurdere effektiviteten og sikkerheden af ​​MK-1200 monoterapi hos deltagere med fremskreden/metastatisk gastrisk/gastroøsofageal junction (GEJ) cancer, esophageal cancer, galdevejscancer og pancreas ductal adenocarcinom, som har modtaget eller været intolerante til alle behandlinger, der vides at give klinisk fordel. Del 1 af undersøgelsen vil være en dosiseskalering for at bestemme den maksimalt tolererede dosis (MTD). Del 2 vil evaluere sikkerheden og effektiviteten af ​​MK-1200 ved 2 forskellige doser
