Randomized Controlled Trial Multicenter StudyRamucirumab versus placebo in combination with second-line FOLFIRI in patients with metastatic colorectal carcinoma that progressed during or after first-line therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine (RAISE): a randomised, double-blind, multicentre, phase 3 study.
Angiogenesis is an important therapeutic target in colorectal carcinoma. Ramucirumab is a human IgG-1 monoclonal antibody that targets the extracellular domain of VEGF receptor 2. We assessed the efficacy and safety of ramucirumab versus placebo in combination with second-line FOLFIRI (leucovorin, fluorouracil, and irinotecan) for metastatic colorectal cancer in patients with disease progression during or after first-line therapy with bevacizumab, oxaliplatin, and a fluoropyrimidine. ⋯ Eli Lilly.

ReviewPrimary endpoints for future prophylactic human papillomavirus vaccine trials: towards infection and immunobridging.
Although available human papillomavirus (HPV) vaccines have high efficacy against incident infection and disease caused by HPV types that they specifically target, new vaccine trials continue to be needed. The goals of these trials could include change of vaccine dose or route of administration (or both), development of second-generation vaccines, and the regional manufacture of biosimilar vaccines. We summarise present thinking about primary endpoints for HPV vaccine trials as developed at an experts workshop convened by the International Agency for Research on Cancer and the US National Cancer Institute in September, 2013. ⋯ However, on the basis of experience from the trials and present knowledge of HPV infection, future efficacy trials for new vaccines can be safely streamlined by the use of persistent HPV infection, which occurs more frequently than CIN2+, and can be more reproducibly measured as a primary endpoint. Immunobridging trials can be sufficient to ascertain immunological non-inferiority for licensure for alternate dosing schedules, bridging to age 26 years or younger, and biosimilar vaccines, with post-licensure surveillance confirming effectiveness. These recommendations are intended to help stimulate continued vaccine development while ensuring appropriate assessment of safety and efficacy.
