Introduction
While two developers are pressing ahead with resubmission plans, a third is disputing US regulator handling and suspending US commercialisation, citing a potentially game changing review of regulatory expectations in the obesity field. This analysis examines the background, current situation and future prospects for these obesity developers at this critical time.

Highlights
Vivus appears to have contingencies aimed at securing approval for Qnexa prior to regulatory change. These feature high risk strategies, however, with no commercialisation partner for Qnexa, and mixed opportunities for its other late stage candidate, short term regulatory success may be turning into a commercial imperative.
Arena has chosen to implement some short cuts to regulatory resubmission for Lorqess, and it is being realistic about likely time-requirements. However, even with pre-approval financial support from Eisai, broader operations are highly reliant on regulatory success, and long term viability is still threatened by guideline re-evaluation.
Orexigen is disputing regulator requirements and putting commercialisation on ice. Its partnering agreement with Takeda and potential for imminent shifting goalposts make this approach as pragmatic and reasoned as earlier regulatory dealings. However, it is unsurprising that the company is actively considering other commercialisation opportunities.
