Description of intervention(s) / exposure
Treatment: Drugs - YH32367

Experimental: YH32367 - Dose Escalation Part: 8 Cohorts. In Dose Escalation part, patients are assigned to receive YH32367 at a starting dose and the dose being escalated/de-escalated in adjacent dose cohorts.
Dose Expansion Part: 2 Cohorts (Cohort 1: Biliary tract cancer, Cohort 2: Solid tumors). Dose Expansion part will consist of multiple cohorts in patients who were treated with at least 1 prior gemcitabine- and/or cisplatin-based therapy, HER2 positive biliary tract cancer(Cohort 1); in patients who were treated with all available standard therapies and have no available options, HER2 positive solid tumor malignancies other than breast and gastric or gastroesophageal junction adenocarcinoma and biliary tract cancer(Cohort 2).


Treatment: Drugs: YH32367
Dose Escalation Part: 8 Cohorts. In this part, approximately 30 patients will be enrolled and patients are assigned to receive YH32367 at a starting dose and the dose being escalated/de-escalated in adjacent dose cohorts will be up to Dose level 8.
Dose Expansion Part: 2 Cohorts(Cohort 1: Biliary tract cancer, Cohort 2: Solid tumors). The part will consist of multiple cohorts in patients who were treated with at least 1 prior gemcitabine- and/or cisplatin-based therapy, HER2 positive biliary tract cancer(Cohort 1); in patients who were treated with all available standard therapies and have no available options, HER2 positive solid tumor malignancies other than breast and gastric or gastroesophageal junction adenocarcinoma and biliary tract cancer(Cohort 2). Each cohort will enroll 65 and 40 patients, respectively.
