QuantRx CEO leaves firm

QuantRx Biomedical Corp., which announced last week that it is moving its headquarters from Doylestown to Portland, Ore., announced today that CEO and chairman Walter Witoshkin has left the firm.

A company spokesman said that Witoshkin, who had been chief executive since 2005, "maintains board-level seats for a number of companies in Pennsylvania and Massachusetts and he will be exploring ways in which to become more actively involved to assist these start up companies with their growth initiatives."

The company said that Witoshkin has spent several decades in the pharmaceutical, health-care and biomedical industries.

The spokesman said that the local staff consisted of six to 10 people; none are remaining in Pennsylvania. The company had already announced that CFO Sasha Afanassiev would not be moving to Portland and would be replaced.

The move is part of the company's transition from development-stage to producing and marketing products, QuantRx said.
