Kimberly A. Burke, the acting-CEO of Echo Therapeutics, has informed the company of her decision to resign. Burke, the company's senior vice president, general counsel and chief compliance officer, was named acting-CEO in June after Echo's contract with its previous acting-CEO, Robert Doman, was not renewed. Doman lost his seat on the company's board of directors in a proxy battle with Platinum Management, Echo's larger stockholder.

Burke first joined Echo as a vice president and corporate counsel in 2008.
