Recruitment will be initiated only after formal approval is obtained from the relevant Ethics Committee or Institutional Review Board.

Herpes zoster is caused by the reactivation of latent varicella-zoster virus (VZV) which stays in latency after its primary infection. Immunosenescence contributes significantly to elevating morbidity associated with aging. Vaccination plays a key role in reducing the disease burden of zoster and the associated complications. We are conducting a study entitled "A Randomized, Blinded, Placebo- and Active-Controlled, Adaptive Phase 2 Clinical Trial to Evaluate the Immunogenicity and Safety of SYS6017 (a Herpes Zoster mRNA Vaccine) in Healthy Participants Aged 40 Years and Above".

This Phase I, open-label, multicenter study evaluates the safety, tolerability, pharmacokinetics, and preliminary efficacy of SYS6005 in advanced malignancies, comprising dose-escalation and expansion phases. The escalation phase employs a BOIN design with accelerated titration across seven dose levels, featuring a 21-day DLT observation period in Cycle 1, with dose adjustments guided by a Safety Monitoring Committee. In the expansion phase, one or more dosing regimens and tumor types will be selected, and participants will receive SYS6005 R2PD for further exploration and validation. Treatment continues until disease progression, unacceptable toxicity, or other discontinuation criteria. Safety monitoring includes AEs, labs, and ECOG PS, while efficacy is assessed via imaging. PK and immunogenicity samples are collected, and survival is tracked quarterly until death or study end. The study aims to determine the maximum tolerance dose (MTD)/recommended phase 2 dose (RP2D) and characterize SYS6005's clinical profile.

Herpes zoster is caused by the reactivation of latent varicella-zoster virus (VZV) which stays in latency after its primary infection. Immunosenescence contributes significantly to elevating morbidity associated with aging. Vaccination plays a key role in reducing the disease burden of zoster and the associated complications. This randomized, observer-blind, placebo-controlled, adaptive phase 1 trial aims to evaluate the safety and immunogenicity of an investigational zoster mRNA vaccine in healthy participants aged 40 years or more.

The study consists of two phases. Phase 1b and Phase 2. Phase 1b aims to evaluate the safety, tolerability, and preliminary efficacy of SYS6010 as a monotherapy and in combination with SYH2051, and to determine the recommended Phase 2 dose (RP2D) for subsequent Phase 2 studies. Phase 2 aims to assess the efficacy and safety of SYS6010 monotherapy or in combination with SYH2051 compared to investigator-selected chemotherapy in patients with EGFR-expressing, unresectable locally advanced or metastatic advanced breast cancer.
