PHOENIX 1 is a phase 3 study evaluating the efficacy and safety of ustekinumab (Centocor), a fully human interleukin-12/23p40 monoclonal antibody, in patients with moderate-to-severe chronic plaque psoriasis. The study randomized 766 patients to receive ustekinumab 45 mg, ustekinumab 90 mg or placebo at weeks zero and four. Data from 52 weeks and 76 weeks show high proportions of patients are maintaining PASI 75 responses with maintenance injections every 12 weeks.
The results of a three-year study with efalizumab show that patients with moderate-to-severe psoriasis are able to maintain high PASI scores, reflecting long-term hope for disease-free intervals.
The phase 3 EXPRESS II trial data show infliximab (Remicade, Centocor) maintenance treatment with regularly administered infusions is associated with better psoriasis control and fewer infusion reactions than intermittent, as-needed dosing. A composite analysis of infliximab phase 2 and 3 study data shows consistently dramatic improvements across all four body regions evaluated in the studies.
The proposed new rules for sunscreens issued by the FDA have focused attention on understanding the different methods available for assessing UVA protection. Considering the limitations of various tests and real-world product use patterns, it is important that a sunscreen demonstrate both high levels of in vivo and in vitro protection against UVA as well as a high SPF level.
In vitro studies evaluated the transmission profiles and photostability of three commercially available sunscreens, as well as their activity for protecting against UV-induced cytotoxicity and genotoxicity.
