Tildrakizumab (trade name Ilumya (USA)/Ilumetri (European Union)) is a monoclonal antibody designed for the treatment of immunologically mediated inflammatory disorders.[1] In the United States, it is approved for the treatment of moderate-to-severe plaque psoriasis.[2]

Tildrakizumab was designed to block interleukin-23, a cytokine that plays an important role in managing the immune system and autoimmune disease.

History

Originally developed by Schering-Plough, this drug became part of Merck's clinical program, following that company's acquisition of Schering-Plough.

In September 2014 Sun Pharmaceutical acquired worldwide rights to tildrakizumab for use in all human indications from Merck in exchange for an upfront payment of U.S. $80 million. Upon product approval, Sun Pharmaceutical will be responsible for regulatory activities, including subsequent submissions, pharmacovigilance, post approval studies, manufacturing and commercialization of the approved product. [3]

As of March 2014, the drug was in phase III clinical trials for plaque psoriasis. The two trials enrolled nearly 2000 patients. [4][5]

In 2016, tildrakizumab became the first IL-23p19 inhibitor to demonstrate positive results in Phase-3 clinical trials for the treatment of moderate-to-severe plaque psoriasis, further validating the importance of the role of IL-23 in psoriasis. Sun Pharma signed a licensing pact with Spain's Almirall for marketing tildrakizumab in Europe [6]

Approvals and indications

In March 2018, it was approved by the Food and Drug Administration for the treatment of moderate-to-severe plaque psoriasis as an injection for subcutaneous use in the United States.[2] In September 2018, it was approved by the European Commission for the treatment of adult patients with moderate-to-severe chronic plaque psoriasis who are candidates for systemic therapy.[7]
