Summary
ABSTRACT
Background: Although historically neglected in clinical research, negative symptoms of schizophrenia are now considered distinct targets of pharmacotherapy. While second-generation antipsychotic treatments were heralded as having a greater therapeutic impact on negative symptoms than their conventional antipsychotic counterparts, the size of this effect is modest. Adjunctive medications such as antidepressants offer limited efficacy, while stimulants have a poor risk–benefit profile. More recently, promising results have been demonstrated with pro-glutamatergic agents such as glycine or D-cycloserine, although a larger trial found no advantage with either agent compared with placebo. Modafinil, a novel wakefulness-promoting agent, is an intriguing candidate for adjunctive pharmacotherapy to treat negative symptoms in schizophrenia. We explored this therapeutic potential through a placebo-controlled trial of patients with prominent negative symptoms. Methods: We randomly assigned patients with schizophrenia or schizoaffective disorder to treatment with either modafinil or placebo for 8 weeks. Double-blind assessments of clinical symptoms and neurocognition were administered at baseline and every 2 weeks thereafter. Results: Twenty subjects were enrolled (N = 10 modafinil, N = 10 placebo). There were no significant differences between modafinil and placebo for changes in negative symptom ratings, the primary study endpoint. However, modafinil treatment was associated with a greater rate and degree of global improvement at study endpoint compared with placebo. No significant worsening of psychopathology was observed and modafinil was well-tolerated. Interpretation: Although no effect on negative symptoms was found, adjunctive therapy with modafinil may result in global improvements in patients with schizophrenia who have prominent negative symptoms.
