Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

Glioblastoma (GBM) is the most common malignant primary tumor of the brain with an annual incidence of approximately 3/100.000. Since 2005 the treatment for newly diagnosed GBM consisted of maximal surgical resection, approx. 60 Gy of radiotherapy together with chemotherapy using temozolomide (TMZ), followed by 6 cycles of maintenance chemotherapy. This treatment regimen demonstrated increased median overall survival (OS) from 12.1 to 14.6 months in comparison to surgery and radiotherapy alone in 2005. Since 2005, despite plenty of clinical phase III trials conducted, Tumor Treating Fields (TTFields) therapy was the first treatment shown to significantly increase median progression-free survival (PFS), OS and one to five year survival rates compared to the previous standard of care. These results led to FDA approval of TTFields for newly diagnosed GBM and were acknowledged since then by several guidelines recommending TTFields for GBM therapy (e.g. NCCN guidelines for CNS cancers V.1.2018, RCC guideline tumörer I hjärna och ryggmärg 2020-01-14 V3.0, DGHO guideline for glioma in adults ICD-10 C71 March 2019). Today, several national committees in Europe already list TTFields as reimbursed treatment (e.g. Austria, Sweden, Germany). Data with TTFields therapy in real-world setting is limited and therefore further evaluation of different treatment aspects of TTFields therapy in clinical routine are of interest. In particular the QoL-related aspects neurocognitive functioning, daily activity and sleep quality in this patient cohort is of major interest, given the limited life expectancy with this disease. This non-interventional study aims to investigate change over time in neurocognitive functioning, sleep quality, and activity in daily life as important determinants of QoL in a large cohort of GBM patients in Germany treated with TTFields in routine clinical care using low-threshold, electronic PRO and modern automated tracking data analyses. The gained results will allow even better understanding of TTFields therapy in daily life of GBM patients and consequently, better informing patients about what to expect when starting this therapy, increasing therapy compliance even further in the long-term.

newly diagnosed GBM with clinical indication for TTFields
Device: - TTFields
Tumor Treating Fields (TTFields) help slow down or stop glioblastoma cancer cells from dividing by disrupting dividing mechanism of cancer cells leading to apoptosis. TTFields are low-intensity, intermediate frequency, alternating electric fields delivered continuously through adhesive patches, called transducer arrays, to the area of the brain where the GBM tumor is located. These transducer arrays are applied to the scalp and are connected to the wearable and portable device. TTFields are approved for the treatment of newly diagnosed and recurrent GBM.
