Dexamfetamine Sulphate in Patients With Glioma Suffering From Severe Asthenia

The main purpose of this study is to estimate the efficiency at 3 months of dexamfetamine sulphate on the MFI 20 scale in severe fatigue of patients with stabilized gliomas.

Quality of life of patients with stabilized gliomas is often impacted by a severe physical and psychological fatigue resulting from both tumor and side effects of treatments.

It is a randomized double blind Placebo-Controlled Trial evaluating the effect of dexamfetamine sulphate on severe fatigue in glioma patients. Half of the participants will receive dexamfetamine sulphate and the other half will receive a placebo. Neither the participant nor the study doctor will know what group they are in.

The main objective is to assess the impact at 3 months of dexamfetamine sulphate in patients suffering from a RANO stable or responsive glioma complaining of a severe fatigue (quantified by the Multidimensional Fatigue inventory - MFI 20 scale).

The secondary objectives include: evaluation of side effects, quality of life, cognitive functions, depression, variation in time of both fatigue scales MFI 20 and VAS.

58 patients will be included. In patients complaining of severe asthenia, with a non progressive neuro-oncological disease, and without criteria of depression revealed by HAD (Hospital Anxiety and Depression) scale, evaluation of fatigue will be done with the MFI 20 scale. Patients with a MFI 20 score ≥60/100 and corresponding to inclusion criteria will be invited to participate.

After randomisation, a baseline evaluation will be done, including MFI20, Norris VAS, EORTC QLQ-C30, Mattis scale, Trail Making Test, Grober and Buschke, Wisconsin Card Sorting Test , HAD scale and Marin scale.

Patients will receive, in a double blinded way, six pills a day either of dexamphetamine sulfate (15 mg\*2) or of placebo, during 3 months, after an initial phase of progressive increasing levels of dose every 10 days, depending on tolerance.

The evaluation of fatigue, quality of life will be done every month during the 3 months of treatment. The cognitive evaluation will be done at 3 months.

The main criteria of evaluation is the variation during 3 months of the MFI 20 score in non progressive patients.
