French drugmaker Sanofi-Aventis is in talks to invest in Hadasit Bio-Holdings, the Israeli biotech holding company said on Tuesday.

Hadasit said the potential investment would be in its KHAR Medical unit, but that no deal had yet been reached. It noted that it was responding to a report in Israel's Calcalist newspaper.

Hadasit, the technology transfer company of Jerusalem's Hadassah University Hospital, said the deal could be thwarted by the disclosure of the talks in the newspaper.
