Extended-release intramuscular paliperidone palmitate (Xeplion®; Invega® Sustenna®) [henceforth referred to as intramuscular paliperidone palmitate] is a long-acting injectable (LAI) formulation of the well established atypical antipsychotic agent paliperidone (9-hydroxyrisperidone), which is the major active metabolite of risperidone. This article reviews, from an EU perspective, the therapeutic efficacy and tolerability of intramuscular paliperidone palmitate in the treatment of adults with schizophrenia, and the pharmacology of paliperidone that is relevant to the intramuscular formulation. Intramuscular paliperidone palmitate 25-150 mg equivalents (mg eq.) effectively reduced symptoms of schizophrenia in most short-term (9-13 weeks) placebo-controlled trials, as demonstrated by improvements in Positive and Negative Syndrome Scale (PANSS) total scores from baseline to endpoint that were significantly greater in intramuscular paliperidone palmitate than placebo recipients. ⋯ The tolerability of intramuscular paliperidone palmitate was generally acceptable in clinical trials of schizophrenia. No new safety concerns were revealed compared with oral paliperidone, except for injection site-related reactions. In conclusion, intramuscular paliperidone palmitate is a useful option for the treatment of patients with schizophrenia.

Bevacizumab is a recombinant, humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody that neutralizes the biological activity of VEGF and inhibits tumour angiogenesis. In two pivotal, well designed, phase III, clinical trials (GOG-0218 and ICON7) in women with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer, first-line treatment with bevacizumab in combination with standard chemotherapy (carboplatin plus paclitaxel) followed by maintenance treatment with bevacizumab alone significantly prolonged progression-free survival relative to standard chemotherapy. ⋯ In ICON7, HR-QOL did not differ to a clinically significant extent between patients receiving bevacizumab plus standard chemotherapy followed by bevacizumab maintenance and those receiving standard chemotherapy alone. Bevacizumab combination therapy had generally acceptable tolerability in these studies, with the nature of adverse events generally similar to that observed in previous clinical trials in patients with other solid tumours.
