(Reuters) - Pfizer Inc (NYSE: PFE) on Monday reported a 30% rise in quarterly profit, helped by demand for its branded treatments such as Ibrance, Eliquis and Xeljanz.

Pfizer, which was scheduled to report its second-quarter earnings on Tuesday, also said it would combine Upjohn, its off-patent drugs business, with Mylan NV (NASDAQ: MYL).

Pfizer said net income rose to $5.05 billion, or 89 cents per share, in the second quarter, from $3.87 billion, or 65 cents per share, a year earlier.

Revenue fell 1.5% to $13.26 billion.
