Durect said a Phase III clinical study designed to measure the safety and efficacy of its post-operative pain relief drug Posidur in abdominal surgical procedures didn't yield statistically significant results.

Family Dollar Stores Inc.'s (FDO) fiscal first-quarter earnings rose 8.1% as the discount retailer's same-store sales improved due to higher traffic and customer transaction values. However, shares slid 2.5% to $56.50 in premarket trading as revenue missed analyst expectations.

(RT) swung to a loss in its fiscal second quarter on higher costs and interest expense, as predicted, while the casual-dining chain reported another quarter of comparable sales declines.
