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.

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.

Additional Details

The trial is conducted as a multicenter, open-label, Phase I/II trial to evaluate the efficacy and safety of VXM01 in combination with avelumab in subjects with resectable and non-resectable progressive glioblastoma following tumor resection and radiochemotherapy containing temozolomide. The trial will be performed in 30 subjects with progressive glioblastoma:

  • - 24 subjects who will not be candidates for a tumor re-operation (non-resectable subjects) - 6 subjects who will be candidates for a tumor re-operation (resectable subjects) The trial, for each subject, will consist of a screening period, a treatment and observatioon phase of 60 weeks including, a treatment phase of up to 48 weeks with prime and boosting administrations of VXM01 in combination with avelumab and an observation phase of 12 weeks and with an end of trial visit at Week 60.
Subjects will receive VXM01 in combination with avelumab up to Week 48. The end of study (EoS) visit assessments will be performed Week 60.
