Alzheimer's disease (AD) is a debilitating neurodegenerative illness affecting over 35 million people worldwide. Solanezumab is a monoclonal antibody that binds to β-amyloid (Aβ), a protein that plays a key role in the pathogenesis of AD. The drug is currently being investigated in Phase III trials as a disease-modifying treatment for AD. ⋯ Solanezumab can neutralize soluble Aβ peptides, which may represent the more neurotoxic of the Aβ species. Phase II findings support the compound's safety, which has been a concern for some Aβ immunotherapies. Cerebrospinal and plasma biomarker changes with solanezumab treatment are encouraging. Results of the ongoing Phase III trials will be instrumental in determining the drug's clinical significance.

Intensive chemotherapy of metastatic colorectal cancer: weighing between safety and clinical efficacy: Evaluation of Masi G, Loupakis F, Salvatore L, et al. Bevacizumab with FOLFOXIRI (irinotecan, oxaliplatin, fluorouracil, and folinate) as first-line treatment for metastatic colorectal cancer: a phase 2 trial. Lancet Oncol 2010;11:845-52.
This paper evaluates a recent study whereby a four-drug combination regimen adding bevacizumab to triplet fluorouracil, oxaliplatin and irinotecan chemotherapy is described for the first-line treatment of metastatic colorectal cancer. It extends the use of intensive medical treatments combining chemotherapy and the VEGF inhibitor bevacizumab, opening new perspectives for the design of four-drug intensive regimen-associating chemotherapy and targeted agents. In the future, these four-drug intensive regimens should be further improved for efficacy:toxicity ratio and verification in randomized trials.
