According to market research in 2024, amisulpride continues to be widely used in Europe. Among a select group of European countries including
Germany, France, Italy, Spain, and several others, there were at least two million monthly prescriptions per year for amisulpride. Among these European prescriptions for amisulpride, our data suggest that approximately 60% are for schizophrenia
and schizoaffective disorders (a mental health condition that includes symptoms of both schizophrenia and mood disorders), approximately 20% are for mood disorders, approximately 14% are for anxiety, and the remainder are for a variety of other
indications.

Amisulpride has also been studied for the treatment of predominantly negative symptoms of schizophrenia in three independent
placebo-controlled trials conducted by third parties. A trial conducted in 1995 evaluated two doses of amisulpride, 100 and 300 mg per day, versus placebo for six weeks of treatment. In this trial, the two amisulpride-treated arms showed a reduction
in the Scale for the Assessment of Negative Symptoms, or SANS, of approximately 39 to 45 points compared with a reduction of 22 points in the placebo arm (p = less than 0.02). P refers to “p-value,” the conventional method for
determining the statistical significance of a result, which represents the probability that random chance caused the result (e.g., a p-value = 0.01 means that there is a 1% probability that the difference between the control group and the treatment
group is purely due to random chance). Generally, a p-value less than 0.05 is considered statistically significant. The SANS scale is a 25-item scale that assesses negative symptoms across five domains: affective blunting, alogia, avolition-apathy,
anhedonia-asociality, and attentional impairment. A trial conducted in 1999 evaluated two doses of amisulpride, 50 and 100 mg per day, versus placebo for 12 weeks of treatment. In this trial, the two amisulpride-treated arms showed a reduction
in SANS of approximately 25 points compared with a reduction of 13 points in the placebo arm (p = 0.0002). A trial conducted in 1997 evaluated 100 mg per day of amisulpr
