PARIS (AP) — French drug maker Sanofi said Thursday its earnings soared in the fourth quarter as lower restructuring costs offset a hefty charge related to one of its key multiple sclerosis treatments.

Paris-based Sanofi reported net profit of 1.06 billion euros ($1.4 billion) in the fourth quarter, up from 388 million euros a year earlier. Last year’s profit was hammered by over 800 million euros worth of restructuring costs.
