HOPE FOR PERSONALISED TREATMENT OF GLIOBLASTOMAS

Open / close summary

Today in France, about 5000 new people with malignant primary brain tumour are diagnosed each year. The ICM teams’ ambition is to develop personalised therapies based on the patients’ tumour genetic profile.

Through the Gliotex experimental therapy platform (supported by the ARC Foundation for Cancer Research and by the Brain Tumours Research Association), co-directed by Ahmed Idbaih and Jean-Yves Delattre, specific therapies are implemented according to the tumour mutation profile. In this context, Marc Sanson’s team has tested an inhibitor targeting the oncogene*, MDM2, which leads to gene amplification in some tumours. Researchers have demonstrated that cells with this mutation respond electively to this inhibitor.
These results are very encouraging for the development of personalised therapies in human and give hope for the establishment of a phase 1 clinical trial.
