Tildrakizumab is a monoclonal antibody designed for the treatment of immunologically mediated inflammatory disorders.[1]

Tildrakizumab was designed to block interleukin-23, a cytokine that plays an important role in managing the immune system and autoimmune disease. Originally developed by Schering-Plough, this drug is now part of Merck's clinical program, following that company's acquisition of Schering-Plough.

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. [2]

As of March 2014, the drug was in phase III clinical trials for plaque psoriasis. The two trials enrolled nearly 2000 patients. [3][4]

In 2016, Tildrakizumab becomes 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 [5]
