Global sales of Genmab's cancer drug Darzalex rose to $3.67 billion in the third quarter, a 22% increase from the same period a year earlier, according to a company announcement on Tuesday.

The sales figures for the multiple myeloma treatment were reported by partner Johnson & Johnson, which markets the drug globally.

Sales in the U.S. totaled $2.09 billion, while sales in the rest of the world reached $1.58 billion, the company said.

Genmab, which developed Darzalex, receives royalties from Johnson & Johnson that are helping to fund the company's strategic shift, including its recent agreement to acquire Merus for approximately $8 billion.

The deal, announced in late September, is part of Genmab's strategy to build a pipeline of wholly owned drugs and reduce its reliance on royalty income.

"The proposed acquisition of Merus clearly aligns with our long-term strategy," Jan van de Winkel, President and Chief Executive Officer of Genmab, said when the deal was announced.

"It has the potential to significantly accelerate our evolution into a global biotechnology leader by providing durable growth for the company well into the next decade."
