Columbia-based Osiris Therapeutics Inc., a biotechnology company developing stem cell-based treatments, beat Wall Street analysts' estimates with a reported loss of $4.3 million in the second quarter, which ended June 30.
The firm, which earlier this year drew international headlines for having the world's first stem cell drug approved by a major country, posted a loss of 13 cents per share. Analysts polled by MarketWatch had expected a 15-cent-per-share loss. The company said its revenues from biosurgery products — which are used to improve wound healing and tissue regeneration — rose 43 percent, to $1.6 million, from the first quarter.
