Xerostomia Due to Radiotherapy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

MRI - Guided Adaptive RadioTHerapy for Reducing XerostomiA in Head and Neck Cancer (MARTHA-trial)

Start date: October 15, 2019
Phase: N/A
Study type: Interventional

Radiotherapy is the main treatment for locally advanced squamous cell carcinoma of the head and neck (SCCHN). Many advances regarding tumor control and patient survival have been made over the past decades. However, treatment-induced toxicity remains a crucial problem, leading to reduced quality of life and permanent impairment for many survivors. Xerostomia is up to this day the leading cause of late toxicity for these patients. Toxicity has been reduced by implementation of modern image guided radiotherapy (IGRT) and intensity-modulated radiotherapy (IMRT), but the low soft-tissue contrast of routine x-ray image guidance does not allow exact planning adaptation and daily imaging is associated with high radiation exposure. Furthermore, despite the routinely use of IMRT, rates of clinically relevant xerostomia (i.e. grade 2 or worse) are still common and reported in approximately 38%. Recently developed hybrid machines (MRidian®-CE approval since 2016), consisting of a linear accelerator and an integrated low-field MRI, could allow a) better visualization of tumor and organs at risk, such as parotid glands during patient positioning and daily treatment, b) daily imaging without additional radiation exposure, c) narrowest established safety margins for the treatment volumes, and finally d) repetitive adaptation of target volumes according to changes in patient weight and tumor anatomy during the radiotherapy course. These procedures would facilitate a high-precision treatment and help reduce dose exposure of critical structures.
