Depending on how the data turn out, the Phase IIb FRONTIER 1 study of Protagonist Therapeutics, Inc. and Johnson & Johnson subsidiary Janssen Biotech Inc.’s interleukin-23 receptor (IL-23R) antagonist, JNJ-2113, suggests the drug could have a competitive edge against those with the same target thanks to its oral availability in patients with moderate-to-severe plaque psoriasis. The results also set it up as a potential competitor to oral TYK2 and IL-17 inhibitors.
