Personalized neoantigen mRNA vaccine for rhabdomyosarcoma

Official title: Exploratory Study of Personalized mRNA Vaccine in Patients With Refractory Rhabdomyosarcoma

Run by Chinese PLA General Hospital · NCT06932861 · Data updated 2026-11-12

A personalized mRNA vaccine, given with an anti-PD-1 antibody and CpG adjuvant, is being tested in patients with refractory rhabdomyosarcoma to see if it can help prolong life.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 6 years or older with rhabdomyosarcoma that persists or progresses after standard treatment and who have no other effective options, good performance status, and expected survival over 6 months.

Probably not a fit

Patients with rapidly progressing disease or poor performance status who do not mount an immune response may not experience benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This early-phase study tests a patient-specific neoantigen mRNA vaccine in combination with toripalimab and CpG-1018 for rhabdomyosarcoma that has not responded to standard therapy. The vaccine design uses the individual tumor’s mutations to tailor treatment. The study aims to evaluate safety and any signs of benefit, with patients receiving the vaccine alongside the immune therapy and adjuvant. Eligibility includes adults and children (6 years and older) with adequate performance status and limited disease progression. The trial is conducted at the Chinese PLA General Hospital in Beijing and led by Xinxin Zhang.

Why it matters

Potential benefit: If successful, patients could experience longer survival and potential tumor control through a personalized vaccine approach in combination with immune therapy.

How similar studies have gone: Similar personalized cancer vaccines have shown safety and hints of activity in other solid tumors, but this exact combination for rhabdomyosarcoma is exploratory.
