Arm Intervention/treatment
Active Comparator: RPh201 group
7 patients will receive the treatment
Drug: RPh201
400 microliter s.c. twice a week for 3 months

Placebo Comparator: non RPh201 group
3 patients will receive placebo
Drug: Saline
400 microliter Saline solution s.c. twice a week for 3 months

Primary Outcome Measures :
  1. consciousness level measured clinically [ Time Frame: 6 months ]
    Each patient will undergo a behavioral assessment (using the Coma Recovery Scale Revised) before treatment and every 2 weeks during the treatment period as well as 3 months following the end of the treatment. Complete blood counts, electrolytes, liver function tests, renal function tests and ECG will be performed every two weeks.

Secondary Outcome Measures :
  1. Functional magnetic resonance imaging of cortical activity [ Time Frame: 6 months ]
    3 scans will be performed: before treatment, after three months of treatment and 3 months after cessation of treatment. Scanning sessions will include a hierarchical auditory paradigm, an imagery task and resting state fMRI
