Study to Evaluate the Safety and Tolerability of ABL501, and to Determine the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D) of ABL501 in Subjects With Any Progressive, Locally Advanced (Unresectable) or Metastatic Solid Tumors
- Registration Number
- NCT05101109
- Lead Sponsor
- ABL Bio, Inc.
- 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.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 24
- 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
- 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.

- Secondary Outcome Measures
Name Time Method number of subject with anti-drug antibodies (ADAs) From Day 1 until confirmed CR, disease progression, unacceptable toxicity or subject/investigator's decision to terminate the study participation, assessed up to 24 months Incidence of anti-drug antibodies (ADAs) will be analyzed to evaluate the immunogenicity of ABL501
Pharmacokinetic profile of ABL501 From Day 1 until confirmed CR, disease progression, unacceptable toxicity or subject/investigator's decision to terminate the study participation, assessed up to 24 months serum concentration of ABL501 will be collected and analyzed to evaluate the PK of ABL501
