Phase 1
Recruiting
Conditions
Advanced or Recurrent Solid Tumors
Interventions
Registration Number
NCT06541639
Lead Sponsor
Peking University
Brief Summary

The goal of this clinical trial is to learn the side effects, safety and effect of a tumor vaccine (EVM16) alone or in combined with an anti-PD-1 antibody (tislelizumab) . This clinical trial will include solid tumor patients who failed standard treatment.

The main questions to answer are:

Safety of EVM16. Suitable dose of EVM16. Effects of EVM16 combined with tislelizumab.

Primary Outcome Measures
NameTimeMethod
safety and tolerabilityFrom the first study intervention to 90 days after the last study intervention.

The incidence and severity of adverse events (AEs) and serious adverse events (SAEs), the incidence of dose-limiting toxicity (DLT) (only in phase Ia), and the incidence of AEs of grade 3 or higher were assessed according to the NCI CTCAE v5.0 in the treatment of EVM16 alone as well as EVM16 in combination with Tislelizumab.

RP2D for EVM16During the intervention, up to approximately 1 year.

Based on safety, tolerability, immunogenicity to determine RP2D.

Secondary Outcome Measures
NameTimeMethod
immunogenicity of EVM16during the intervention, up to 1 year

Based on proportion of IFN-γ-positive T cells and/or T cell receptor sequences after EVM16 administration to assess the immunogenicity of EVM16 in subjects with advanced or recurrent solid tumours.

time to remission (TTR) of EVM16 in combination with tislelizumabFrom date of first study dose until the date of disease progression, or until the patient start subsequent anti-cancer treatment, or death, or lost to follow up or the study ends, whichever occurs first.

Time from enrollment to objective response (PR and CR) as assessed by the investigators according to RECIST v1.1 in EVM16 combined with tislelizumab arm.

objective response rate (ORR) of EVM16 in combination with tislelizumabFrom date of first study dose until the date of disease progression, or until the patient start subsequent anti-cancer treatment, or death, or lost to follow up or the study ends, whichever occurs first.

Proportion of patients with partial response (PR) and complete response (CR) as assessed by the investigators according to RECIST v1.1 in EVM16 combined with tislelizumab arm.

disease control rate (DCR) of EVM16 in combination with tislelizumabFrom date of first study dose until the date of disease progression, or until the patient start subsequent anti-cancer treatment, or death, or lost to follow up or the study ends, whichever occurs first.

Proportion of patients with partial response (PR) , complete response (CR) and stable disease (SD) as assessed by the investigators according to RECIST v1.1 in EVM16 combined with tislelizumab arm.
