Thymalfasin treatment combined with radiotherapy for advanced solid tumors

Is this trial a fit for you?

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

What this trial studies

This Phase II trial investigates a novel treatment approach for patients with advanced refractory solid tumors using thymalfasin, a peptide that stimulates T lymphocyte activation, in combination with hypofractionated radiotherapy and sequential administration of a PD-1/PD-L1 inhibitor and GM-CSF. The treatment involves an activation cycle where thymalfasin is administered based on T lymphocyte counts, followed by targeted radiotherapy to metastatic lesions and subsequent immunotherapy. Patients will undergo at least two activation cycles, with maintenance therapy continuing the regimen of thymalfasin, GM-CSF, and PD-1/PD-L1 inhibitors. The goal is to evaluate the efficacy and safety of this combined approach in a challenging patient population.
