Should Arthur Levinson and some of the team he has assembled at Genentech leave it will be a big loss for Roche, as it was his team that helped bring a series of new drugs to the market such as Avastin, Herceptin, and Rituxan to bring Genentech sales from $1 billion in 1999 to $9 billion in 2007. As drug companies buy biotechs in large numbers, with $70 billion in deals this year almost twice the toal for 2007, the question remains whether the drug companies have succeeded in retaining talent as consolidation yields cost savings but does not improve drug discovery. Drug companies are struggling with this, and a couple of models have emerged for keeping minds engaged in scientific discovery satisfied that they have the freedom to operate as they always have and work with the teams they have assembled, similiar to the work style and in the similiar culture as before. Almost like walking into the offices they use as if its like before. J&J has come up with a hub and spoke model to acquire companies and then leave them alone- preserving their management teams, unique cultures and brands. Centocor was bought in 1999 by J&J and 10 of the top executives stayed on and developed Remicade, a drug for inflammatory disease that has sales of $3.3 billion. Glaxo has developed a new structure under new CEO Andrew Witty, which breaks up the primary research labs into "discovery performance units" or DPUs, which also include new biotech startups. In April Glaxo acquired Sitris, a Cambridge, Massachusetts startup. The company had come up with a new science for tackling heart disease, diabetes and other diseases associated with aging. Harvard trained scientist and CEO, Christoph Westphal, went with Glaxo turning down other companies because the independence of the DPU appealed to him. Each DPU has a 3 year budget and this also appealed to Westphal. He could walk into the labs, says Westphal as if nothing had changed. Is Roche making a mistake in acquiring Genentech when it could have left it alone. Are the consolidation savings worth it if some of the discovery team at Genentech leaves and there is the feeling that the culture will change, and if Levinson feels that he was not consulted about Roche's move. These are questions that remain even when Roche's CEO, Severin, says he does not want to change things at Genentech because Roche's actions will speak louder than its words. ...
