Apremilast has been linked to a low rate of serum enzyme elevations during therapy, but has not been implicated in cases of clinically apparent acute liver injury.</p></div><div id="Apremilast.Background"><h3>Background</h3><p>Apremilast (a pre' mi last) is a small molecule inhibitor of the enzyme phosphodiesterase-4 (PDE-4) that is responsible for the degradation of cyclic adenosine monophosphate (cAMP), thereby blocking an important step in the inflammatory signaling of immune effector cells including T lymphocytes, monocytes and macrophages. Apremilast therapy has been shown to decrease the level of circulating proinflammatory cytokines and to improve symptoms in cases of psoriatic arthritis that have not responded to conventional therapies. Apremilast was approved as oral therapy of active psoriatic arthritis and for moderate-to-severe plaque psoriasis in the United States in 2014. It has been used experimentally and off-label to treat scalp and nail psoriasis and is under evaluation as therapy of other chronic inflammatory conditions. Apremilast is available in tablets of 10, 20 and 30 mg under the brand name Otezla. The recommended initial dose is 10 mg twice daily, which can be increased based upon tolerance to the recommended maintenance dose of 30 mg twice daily. Side effects include diarrhea, nausea, weight loss and headache which generally arise during the first few weeks of treatment and improve thereafter. Rare, but potentially severe adverse events include reactivation of tuberculosis, depression, severe infections and increased risk of malignancy.</p></div><div id="Apremilast.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>In multiple, large scale randomized controlled trials of apremilast in psoriasis and psoriatic arthritis, serum enzyme elevations were no more frequent among recipients of apremilast than placebo treatment. In these studies, serum <a class="def" href="/books/n/livertox/glossary/def-item/glossary.alanine-aminotransferase-alt-/">ALT</a> values rose above 150 U/L (3 to 4 times ULN) in 0.4% of apremilast- compared to 0.2% of placebo-recipients, and no patient developed clinically apparent liver injury with jaundice. Since approval there have been no published reports of hepatotoxicity attributed to apremilast, but it has had limited clinical use. Because apremilast is immunosuppressive, it may cause reactivation of viral infections including hepatitis B, but such cases have not been reported.</p><p><a class="def" href="/books/n/livertox/glossary/def-item/glossary.likelihood-score/">Likelihood score</a>: E (unlikely cause of clinically apparent liver injury, but experience with its use is limited).</p></div><div id="Apremilast.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism by which apremilast might cause serum aminotransferase elevations or liver injury is not known. It is extensively metabolized by the liver predominantly by the cytochrome P450 system and is susceptible to drug-drug interactions with agents that induce or inhibit CYP 3A4 activity.</p><p>Drug Class: Dermatologic Agents, <a href="/books/n/livertox/PsoriasisDrugs/">Psoriasis Agents</a></p><p>Other drugs used to treat psoriasis: <a href="/books/n/livertox/Acitretin/">acitretin</a>, <a href="/books/n/livertox/Methotrexate/">methotrexate</a>, <a href="/books/n/livertox/TNFAntagonists/">tumor necrosis factor (TNF)-inhibitors</a>, <a href="/books/n/livertox/Secukinumab/">secukinumab</a>, <a href="/books/n/livertox/Ustekinumab/">ustekinumab</a></p></div></div><div id="Apremilast.PRODUCT_INFORMATION"><h2 id="_Apremilast_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Apremilast.BPI" class="box"><p>
