At Forbes's Science Business blog Matthew Herper wonders whether Amgen should acquire Human Genome Sciences. Biotech analyst Geoffrey Porges says it should, and that the price tag could be as high as $6.5 billion. Porges points out that Benlysta, Human Genome's lupus drug, is "one of the hotter biotech products" and that Amgen has more to offer Human Genome than GlaxoSmithKline, which has the rights to co-market Benlysta, does.
