The hepatitis-C drugs posted combined sales of 783 mln sfr in the first half.Roche remains sceptical regarding a cooperation with competitor Novartis AG, Humer told journalists on the sidelines of today’s presentation.Novartis -- which currently holds a 33 pct stake in Roche -- has repeatedly expressed its interest in a merger.
