India the pivotal Phase-3 reSURFACE clinical development program, which consisted of two randomized, double-blind, placebo-controlled trials of more than 1,800 patients across over 200 clinical trial sites. Results from the Phase-3 reSURFACE 1 and 2 studies were published in The Lancet in July 2017, with primary endpoints presented at the 25th European Academy of Dermatology and Venereology (EADV) Congress. Both Phase-3 studies met the primary efficacy endpoints, with an average of 63 percent of patients receiving Tildrakizumab 100 mg achieving 75 percent of skin clearance (Psoriasis Area Sensitivity Index or PASI 75) by week 12, and 77 percent of patients achieving 75 percent skin clearance after 28 weeks (64 percent and 80 percent in reSURFACE 1, 61 percent and 74 percent in reSURFACE 2). Similarly, an average of 57 percent and 66 percent of patients receiving Tildrakizumab 100 mg had a Physician’s Global Assessment (PGA) score of “clear” or “minimal” at weeks 12 and 28, respectively. Additionally, a higher number of Tildrakizumab-treated patients achieved PASI 90 and PASI 100 compared to placebo and etanercept. Tildrakizumab has also been approved and commercialized in Australia under the ILUMYATM brand name and in Europe under the ILUMETRITM brand name. IMPORTANT SAFETY INFORMATION Tildrakizumab is contraindicated in patients with a previous serious hypersensitivity reaction to Tildrakizumab or to any other excipients. Cases of angioedema and urticaria occurred in Tildrakizumab-treated subjects in clinical trial. If a serious hypersensitivity reaction occurs, discontinue Tildrakizumab immediately and initiate appropriate therapy. Tildrakizumab may increase the risk of infection. Treatment with Tildrakizumab should not be initiated in patients with a clinically important active infection until the infection resolves or is adequately treated. Consider the risks and benefits of treatment prior to prescribing Tildrakizumab in patients with a chronic infection or a history of recurrent infection. Instruct patients receiving Tildrakizumab to seek medical help if signs or symptoms of clinically important chronic or acute infection occur. If a patient develops a clinically important or serious infection, or is not responding to standard therapy, closely monitor and discontinue Tildrakizumab until the infection resolves. Evaluate patients for TB infection prior to initiating treatment with Tildrakizumab. Do not administer Tildrakizumab to patients with active TB infection. Initiate treatment of latent TB prior to administering Tildrakizumab. Consider anti-TB therapy prior to initiation of Tildrakizumab in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Patients receiving Tildrakizumab should be monitored closely for signs and symptoms of active TB during and after Tildrakizumab treatment. Sun Pharmaceutical Industries Ltd.

India M ost common (≥1%) adverse reactions associated with Tildrakizumab include upper respiratory infections, injection site reactions, and diarrhea. Adverse reactions that occurred at rates less than 1% but greater than 0.1% in the Tildrakizumab group and at a higher rate than in the placebo group included dizziness and pain in extremity. About the Phase-3 reSURFACE Trials The Phase-3 studies ( reSURFACE 1 and reSURFACE 2 ) were randomized, placebo-controlled, multicenter, three-part studies designed to demonstrate efficacy of Tildrakizumab in moderate- to-severe plaque psoriasis compared to placebo and comparative drug and to assess safety and tolerability. Part one of the studies randomized patients into three or four treatment arms, including Tildrakizumab 100 mg, Tildrakizumab 200 mg, placebo and etanercept (reSURFACE 2 only). After Week 12, patients on placebo were then re-randomized into Tildrakizumab 100 mg and 200 mg treatment arms to proceed into part two of the studies. Finally, in part three of the reSURFACE 1 study, responders (PASI ≥75) and partial responders (PASI ≥50 and PASI <75) to Tildrakizumab were re-randomized after Week 28 to continue the same treatment, a different dose of Tildrakizumab or placebo. Partial and non-responders to etanercept were treated with Tildrakizumab 200 mg in part three of the reSURFACE 2 study. Patients with guttate, erythrodermic, or pustular psoriasis were excluded.
