Soros fund story updated for key drug trial, corrected for gold holdings)

Soros Fund Management

, the fund management arm of billionaire investor George Soros, bulked up on health care and biotechnology in the third quarter, according to the hedge fund manager's quarterly filing of portfolio holdings, released after the market close on Monday.

At the same time, the famed hedge fund manager notably shifted away from one of his favorite investments, the SPDR Gold Trust.

The biggest new addition to the Soros portfolio, on a percentage-of-portfolio basis, was biotechnology play




Soros' big bet on Dendreon came ahead of a key government vote on the company's sole drug this week. An advisory panel is set to vote on Wednesday on whether there is enough evidence to support the claim that Dendreon's Provenge extends life in prostate cancer patients and should be covered by Medicare. Dendreon shares bottomed out in July after it became unclear whether Medicare would pay for the drug use in prostate cancer patients. The drug first became available in the U.S. in April. Medicare sales would generate $1.7 billion a year for Dendreon by 2014, and approval by Medicare could lead to a major Dendreon share rally.
