In addition to suggesting potential new drug targets for atopic dermatitis and psoriasis, the transcriptomes provide a new route to understanding other inflammatory diseases, and provide a template for culturing skin for wound repair, according to the authors of a paper published in the Jan. 22, 2021, issue of Science.
Tonix Pharmaceuticals Holding Corp.’s failure last December in the phase III study called Recovery with TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg dented hopes for patients with civilian and military-related post-traumatic stress disorder (PTSD), but other developers remain in the game.
