The Aviva Premiership club have been looking for a new owner since last July, when Wycombe council withdraw its support for the construction of a new stadium.
In February, Wasps were at "advanced stages of discussions" with four interested parties but those talks have now stalled.
A Wasps statement said on Tuesday: "The board is disappointed to confirm that negotiations, which had been leading towards an imminent takeover of the club, have stalled.
"The board, having taken independent advice, is able to confirm that London Wasps Holdings Limited remains nevertheless a going concern.
"However, the board acknowledges the urgency of the current situation surrounding the club.
"There are on-going active discussions with other potential investors but the club is seeking, using all best endeavours, further expressions of interest."
