An Exploratory Study of Personalized Cancer Vaccine in Adjuvant Therapy of Solid Tumors

May 7, 2026 updated by: Suzhou Abogen Biosciences Co., Ltd.

An Exploratory Study of Personalized Cancer Vaccine (ABO2109) in Adjuvant Therapy of Solid Tumors

The purpose of this study is to evaluate the safety and tolerability of ABO2109 in combination with toripalimab, and to evaluate the immunogenicity, pharmacokinetics, pharmacodynamics, as well as biomarker characteristics of the investigational cancer vaccine. In addition, the antitumor activity of ABO2109 will be assessed during both dose exploration and expansion stages, the accumulative data will support the clinical development of ABO2109.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: Dose Exploration Part
Participants will receive ABO2109 at specified dose defined in the study protocol via an intramuscular (IM) injection every three weeks. The first treatment cycle consists of ABO2109 monotherapy, and combination therapy with toripalimab is initiated from the second treatment cycle onwards.

Drug: ABO2109 Injection personalized cancer vaccine Drug: Toripalimab Anti-PD-1 monoclonal antibody
Experimental: Dose Expansion Part
Participants will receive ABO2109 via an IM injection on Day 1 of each 21-day cycle for up to 9 cycles and Toripalimab via IV infusion on Day 1 of each 21-day cycle until progression, unacceptable toxicity, or up to 13 cycles, whichever is sooner.
