Safety, Tolerability, Immunogenicity, Pharmacodynamic Characteristics, and Preliminary Anti-tumor Activity of Personalized Cancer Vaccines Alone and in Combination With Toripalimab in Participants With Resected NSCLC

July 1, 2026 updated by: The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

A Clinical Study to Evaluate the Safety, Tolerability, Immunogenicity, Pharmacodynamic Characteristics, and Preliminary Anti-tumor Activity of Personalized Cancer Vaccine Alone and in Combination With Toripalimab in Patients With Resected NSCLC

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, as well as preliminary efficacy of a personalized cancer vaccine alone and in combination with toripalimab in patients with resected NSCLC. The study included dose escalation and dose expansion two parts.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ABO2109 combined with toripalimab
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.
Biological: ABO2109 and toripalimab
Biological : ABO2109 Injection personalized cancer vaccine Biological: Toripalimab Anti-PD-1 monoclonal antibody
