Evotec SE is to expand its pharmaceutical services business into biologics with the acquisition of Just Biotherapeutics Inc of Seattle, Washington, US. The deal will give the Germany-based company a capacity to discover and develop protein therapeutics in addition to its existing small molecule business. Evotec will pay an initial $60 million for the company, a figure that could rise to $90 million depending on the achievement of certain milestones within the next three years.
