Disease Progression and Treatment-induced Alterations in Glioblastoma
Study Purpose
Summary of scientific evidence and rationale of this project: Integrative molecular-genetic approaches have provided important insights in the biology of glioblastoma. It has meanwhile become clear, that glioblastoma is not a single tumor entity but comprises different molecular subtypes, which are associated with a distinct genetic/epigenetic signature and prognosis. Multimodal treatment approaches combining radio- and chemotherapy as well as the recent introduction of novel antiangiogenic agents have resulted in increasing survival times and improved quality-of-life of glioblastoma patients. Yet, despite these intense treatment efforts the therapeutic efficacy in glioblastoma patients is limited, leading in virtually all cases to tumor recurrence and death of the patients. As only a limited fraction of glioblastoma patients undergo second neurosurgery at tumor recurrence (< 10%), post-therapeutic samples are rare and no systematic, large-scale studies exist, which address post-therapeutic morphological and molecular alterations in glioblastoma tumor tissue. Yet, these data would help to improve the understanding of mechanisms involved in therapy-resistance and tumor progression, to develop new therapeutic approaches and could pave the way for personalized treatment strategies.

Study Type
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. |

Trial Details

Trial ID:
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. |
NCT02152748 |
|
Phase
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. |
