5. Study Description

Brief Summary
Primary objective: to examine the efficacy and safety of high frequency repetitive transcranial magnetic stimulation (HF rTMS) with H7-coil applied once daily during the twenty days, augmentative to the standard antipsychotic pharmacotherapy and other treatment of negative symptoms in schizophrenia. Targeted population: patients diagnosed with schizophrenia, 18-55 years old with predominant negative symptoms, stable condition for >3 months and unchanged antipsychotic therapy for >1 months and no treatment with antidepressants. Study design: industry independent, multicenter, prospective randomized sham-controlled, two-arms, triple-blind superiority clinical trial with concealed allocation and masked independent outcome assessment. Primary outcome: adjusted median of differences in total SANS score. Adjustment for age, gender, baseline total SANS score, duration of the disorder, and antipsychotic therapy.
