About this study

Official title: 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

Study groups in NCT07583953
Study groupRoleWhat they receive
Dose Exploration PartExperimentalParticipants 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.
Receives: Biological: ABO2109 Injection;Toripalimab
Dose Expansion PartExperimentalParticipants 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.
Receives: Biological: ABO2109 Injection;Toripalimab

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence and nature of dose-limiting toxicity (DLT) with ABO2109 monotherapy (Dose Exploration)

    Measured: From the first dose of ABO2109 through 21 days post-dose for each dose-escalation cohort

  2. Incidence and severity of TEAE, TESAE, and TEAE leading to study treatment interruption or premature discontinuation following study treatment (Dose Exploration)

    Measured: From the start of study intervention until 30 days after the last dose of ABO2109/90 days after the last dose of toripalimab, or until the initiation of new antineoplastic therapy, whichever occurs first

  3. Changes in ECOG performance status score (Dose Exploration)

    Measured: From baseline until 30 days after the last dose of ABO2109/90 days after the last dose of toripalimab, or until the initiation of new antineoplastic therapy, whichever occurs first

  4. DFS based on RECIST Version 1.1. (Dose Expansion)

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing ABO2109 Injection;Toripalimab in people with Solid Tumors, run by Suzhou Abogen Biosciences Co., Ltd..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 13 May 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wei Li (+86 15895401045, liwei10@suda.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and nature of dose-limiting toxicity (DLT) with ABO2109 monotherapy (Dose Exploration) (time frame: From the first dose of ABO2109 through 21 days post-dose for each dose-escalation cohort). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2026.
