Introduction to Saphris (Asenapine)
Saphris, also known as asenapine, is an atypical antipsychotic medication used primarily for the treatment of schizophrenia and bipolar I disorder. Here, we will delve into the clinical trials that have established its efficacy, analyze the current market trends, and provide projections for its future market performance.
Clinical Trials and Efficacy
Schizophrenia Trials
The efficacy of Saphris in treating schizophrenia has been demonstrated through several clinical trials. Two 6-week clinical trials and one maintenance trial in adults have shown that Saphris is effective in reducing symptoms of schizophrenia. In these trials, Saphris was statistically superior to placebo in improving the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression-Severity (CGI-S) scores[1][4].
A notable maintenance trial involved a randomized withdrawal design, where patients initially received sublingual asenapine for 26 weeks. Those who met stability criteria were then randomized to either continue asenapine or switch to placebo. The results showed that asenapine was superior to placebo in delaying relapse or impending relapse[1].
Bipolar Disorder Trials
For bipolar I disorder, Saphris has been evaluated in two 3-week monotherapy trials and one 3-week adjunctive therapy trial. These trials established its efficacy in treating manic or mixed episodes, both as a monotherapy and as an adjunct to lithium or valproate[4].
Transdermal System Trials
Recently, a transdermal system (TDS) formulation of asenapine has been approved, offering a once-daily alternative route of administration. Clinical trials for this formulation have shown that both the 3.8 mg/24 hours and 7.6 mg/24 hours treatment arms were statistically superior to placebo in reducing PANSS and CGI-S scores over six weeks. The safety profile of the TDS is consistent with the existing label for sublingual tablets, with manageable risks such as skin irritation[3].
