The drug will be used to treat moderate to severe plaque psoriasis in adults who are suitable for systemic therapy, the National Medical Products Administration said in a notice.
Johnson & Johnson is positioning Tremfya as an alternative to Novartis's (NVS) - Get Report Cosentyx, Reuters reports. Cosentyx was launched two years ago and is among the top-selling treatments in the $11 billion global psoriasis market.
Earlier this month, Morgan Stanley analyst David Lewis increased his rating of the health-care-products maker to overweight from equal weight.
Lewis said in a note to investors that Johnson & Johnson is "the most under-owned stock in healthcare."
Among other items, Lewis said key drivers in the New Brunswick, N.J., company's pharmaceutical division include strong performances by Tremfya and Spravato, a nasal spray to be used with an oral antidepressant for adults who have treatment-resistant depression.
