Thomas H. Lee Partners LP is in the lead to buy consumer-health assets from GlaxoSmithKline Plc (GSK), and may announce a deal as soon as this week, said two people with knowledge of the matter. THL is close to entering exclusive talks with Glaxo, said the people, who declined to be identified as the matter is private. The companies have yet to agree on price and may not reach a deal, the people said. Bain Capital LLC also submitted an offer for the assets, and Blackstone Group LP (BX) and Prestige Brands Holdings Inc. (PBH) put in a joint bid, they said.
