Re-induction of a Systemic Immune Response After Initial Response With Immune Therapy With Single-dose Radiotherapy in Metastatic or Locally Recurrent Lung Cancer: A Prospective Phase II Trial (Re-Induce 2)
Patients with metastatic non-small cell lung cancer (NSCLC) who after an initial response to immunotherapy of chemo-immunotherapy show diffuse disease progression are treated with chemotherapy, with a median PFS of about 3 months and a high incidence of important toxicity or by continuation of immune therapy when the growth rate of the tumours is low. In a previous study, it was showed that irradiating a single metastatic lesion and continuation of immune therapy resulted in a median PFS time was 4.9 months (95% CI, 3.0-7.0 months). At three months of follow-up, the PFS rate was 62.5%, at six months 37.5% and at 12 months 17.9%. The median OS for all patients was 14.9 months (95% CI, 12.2-21.5 months). Toxicity was hardly observed. This was obtained with a few fractions of radiotherapy. There is biological rationale to deliver this radiation in a single fraction of 10 Gy.
Objective: The primary objective is to investigate if a single fraction of 10 Gy is not inferior to a more fractionated schedule, which would add to the convenience for the patient, even less toxicity and costs.
Study design: Prospective, single-arm phase II trial. Study population: Patients with stage IV NSCLC who initially showed a partial or complete remission under immune therapy alone or concurrent immune therapy and chemotherapy and now show progressive disease according to RECIST 1.1 criteria. At least two different lesions should show progressive disease. Patients should be able to continue the same immune therapy (i.e. no adverse events grade 3 or more).
Intervention: Patients continue the same immune therapy they already received and get radiotherapy to one progressing lesion. The lesion may or may not be symptomatic. The preferred radiotherapy dose is 10 Gy in 1 fraction, but other fractionation schedules (e.g. 24 Gy/ 3 fractions, 30 Gy/ 10 fractions, 20 Gy/ 5 fractions, 20-24 Gy / 1 fraction for stereotactic radiotherapy for brain metastases), including so-called isotoxic strategies are allowed if these are standard for a certain location or palliative indication in the body.
Main study parameters/endpoints: Progression-free survival (PFS).
Introduction of the Maastro Applicator for Endoluminal Boosting in Rectal Cancer: a Pilot Study
The goal of this interventional pilot trial is to confirm that Maastro endoluminal HDR ( High Dose Radiation) contact brachytherapy boosting is feasible and may increase the chance of functional organ sparing of the rectum in patients with rectal cancer. Participants will be treated with chemoradiotherapy and an endoluminal boost with the Maastro applicator.
In-vivo Treatment Verification for HDR Brachytherapy Patients Using an External Imaging Panel
To acquire data during High Dose Rate (HDR) brachytherapy treatments aiming to track the brachytherapy source inside the patient verifying the delivery of the treatment plan.
Medical images (CT,MRI and US) combined with software developed by the investigator will be employed to predict the response of the Investigational product during the treatment and will be used as reference.The IP will be placed on the side of the treatment table and will acquire data during the whole treatment, which will be compared against information derived from the treatment plan. The IP based method can detect errors and information about motion and treatment uncertainties that are not currently available.
