Brief summary

This is a first-in-human (FIH) phase 1 open-label, multicenter, multiple-dose, dose-escalation and dose-expansion study of ABL501 to evaluate the safety, tolerability, MTD and/or RP2D, PK, immunogenicity, preliminary anti-tumor activity, and the PD effect of ABL501 in subjects with any progressive locally advanced (unresectable) or metastatic solid tumors. This study included 2 parts; a dose-escalation part and a dose expansion part.

Detailed description

This is consisted with dose-escalation and dose-expansion study of ABL501 to evaluate the safety, tolerability, MTD and/or RP2D, PK, immunogenicity, anti-tumor activity, and the PD effect of ABL501 in subjects with any progressive locally advanced (unresectable) or metastatic solid tumors.

Interventions

DRUGABL501

ABL501 will be administered biweekly of every 28-day cycle in the dose-escalation. The dosing interval to be used in the dose-expansion part will be re-evaluated based on the emerging safety and PK data from the dose-escalation part of the study.

Inclusion criteria

* Histologically and/or cytologically confirmed any progressive, locally advanced (unresectable), or metastatic solid tumors that have relapsed or are refractory following the last line of treatment and for which prior standard therapy has been ineffective, standard therapy does not exist, or is not considered appropriate. * Subjects with adverse events(AEs) excluding alopecia or Grade 2 toxicities that are deemed stable or irreversible (e.g., peripheral neuropathy) from prior therapy that have improved to Grade 1 or the baseline grade more than 14 days prior to the first administration of study drug. * Subject with adequate hematologic, hepatic, and renal functions confirmed based on the screening laboratory test within 7 days prior to the first administration of ABL501

Exclusion criteria

* Subjects has received prior anticancer monoclonal antibody treatment or investigational therapy within 28 days prior to the first administration of ABL501 or who has recovered (i.e., =\<Grade 1 or at baseline grade) from AEs due to previously administered agent more than 14 days prior to ABL501 administration. * Subject has had prior chemotherapy or radiation therapy within 2 weeks or targeted small molecule therapy within 5 half-lives prior to the first administration of study drug or has not recovered (i.e., =\<Grade 1 or at baseline grade) from AEs due to previously administered agent more than 14 days prior to ABL501 administration * Subject discontinued from prior immunomodulatory therapy due to any intolerable immune-related AE(s) (irAEs) requiring systemic steroid treatment.
