Regeneron Rises, Norwegian Cruises and CVS Health Quits the Habit

Sanofi and Regeneron revealed this week their experimental cholesterol-lowering drug nearly halved the number of heart attacks and strokes in a clinical trial. The analysis offers preliminary evidence that targeting a protein known as PCSK9 could reduce cardiovascular risks for millions. Meanwhile, Norwegian Cruise Line announced it was buying Prestige Cruises for a little over $3 billion this week, adding eight luxury vacation ships to its fleet. The deal gives Norwegian two brands - Oceania Cruises and Regent Seven Seas Cruises - which are marketed as high-end luxury vessels. Finally, CVS stopped selling tobacco products this week, almost a month sooner than planned. CVS Caremark will also now be known as CVS Health.
