NCT06551909

Brief Summary

This is a prospective multicenter study of hypofractionated radiotherapy for the radiation treatment (RT) of solid tumors and in particular for Glioblastoma (in Aim 2). It is based on the results of ongoing studies at our Institute to validate the efficacy of extremely hypofractionated RT in neoadjuvant settings, which observed immunostimulatory effects of RT and the synergy with immune components. The collaboration between San Raffaele Hospital (Milan), the IRCCS Istituto Nazionale dei Tumori Fondazione G. Pascale (Naples) and the San Giuseppe Moscati Hospital of National Relief and High Specialty (Avellino) will ensure that patient recruitment, treatment and monitoring can be translated into facilities of the National Health System using common procedures. The various departments involved will treat patients with the same methods synergistically exploring the immuno/biological factors related to efficacy (and/or toxicity), based on new radioimmunotherapeutic approaches. Clinical and research activity will be developed jointly, drawing on the expertise in radiotherapy, radiomics, oncology, imaging and immunotherapy skills already available.

Study Arms (1)

Treatment arm

EXPERIMENTAL

The 30 patients will receive neoadjuvant stereotactic radiotherapy in 5 fractions delivering 30 GY to PTV and 35-50 GY with Simultaneous Integrated Boost (SIB) to GTV using standard chemotherapy (TMZ) after surgery. GTV will be treated with escalating dose levels from 35 to 50 Gy. Patients will be divided into groups of 5 and will receive in the absence of 2 G4 toxicities per group, the following dose levels: 35-40-42.5-45-47.5 and 50 Gy

Radiation: Neoaddjuvant Stereotactic Radiotherapy with Simultaneous Integrated Boost

Interventions

Patients with Glioblastoma will receive neoadjuvant stereotactic radiotherapy to Planning Target Volume (PTV) to 30 Gy in 5 fractions, and a Simultaneous Integrated Boost delivering 35-50 GY to GTV. Patients will be divided into groups of 5 and will receive (in the absence of 2 G4 toxicities per group), the following dose levels: 35-40-42.5-45-47.5 and 50 Gy. Standard Temozolomide chemotherapy will be prescribed after surgery.

Intervention Model
SINGLE GROUP
Model Details: This is study of feasibility in terms of toxicity of a dose escalation radiotherapy procedure, with 5 patients at each dose level, on 30 patients. The dose will be increased, moving to the next 5 patients, if no more than 1 acute toxicity of grade (G) 4 will be registered. The assumption is that the percentage of patients free from cumulative acute toxicity G≥3 (Common Terminology Criteria of Adverse Events-CTCAE- v5.0 scale) at 1 month after the end of treatment should not exceed 30%. A sample size of 30 patients results in a two-sided 95% confidence interval with a width of 0.328 (0.136-0.464) when the sample proportion is 0.300. Dropouts will be replaced by patients visited later, so as to reach the expected sample. Serum from 30 healthy volunteers, with sex and age characteristics comparable to the patients, will be collected to compare the level of immune biomarkers.
