Outcome Measures

Primary Outcomes (2)

  • Treatment-emergent adverse events (TEAEs) up to Day 21

    To assess the safety and tolerability of YH32367

    in dose escalation part, an average of 21 days

  • Objective Response Rate (ORR)

    To assess the ORR of YH32367 at the recommended Phase 2 dose (RP2D) according to RECIST v1.1 by blinded independent central reviews (BICR)

    through dose expansion part completion, approximately 2.5 year

Secondary Outcomes (12)

  • Area under the serum concentration-time curve from time 0 to the last quantifiable concentration (AUClast)

    up to 66 weeks

  • maximum observed serum concentration (Cmax)

    up to 66 weeks

  • time to reach Cmax (Tmax)

    up to 66 weeks

  • Presence and characterization of YH32367 ADA in serum including titer of ADA and neutralizing antibodies

    through study completion, approximately 3.5 year

  • Objective Response Rate (ORR)

    through study completion, approximately 3.5 year

  • +7 more secondary outcomes

Other Outcomes (3)

  • Immune ORR (iORR)

    through study completion, approximately 3.5 year

  • Immune Duration of Response (iDOR)

    through study completion, approximately 3.5 year

  • Immune PFS (iPFS)

    through study completion, approximately 3.5 year

Study Arms (1)

YH32367

EXPERIMENTAL

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).

Drug: YH32367

Interventions

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 approximately 75 and 40 patients, respectively.

De-identified individual participant data (including data dictionaries) that underline the results reported in study-related publications will be made available during the period beginning 1 year and ending 5 years after all trial primary and secondary endpoints were assessed. Only requests from researchers who provide a methodologically sound proposal will be reviewed and approved by the sponsor. The analysis type should be in accordance with aims in the proposal approved by the sponsor. Proposals should be directed to andrew90@yuhan.co.kr. A summary of the study results will be posted in the publicly accessible database (i.e. clinicaltrials.gov) no later than 1 year after the study's primary completion date.
