Pfizer Inc. will buy Array BioPharma Inc. for $10.6 billion to gain its promising new medicines for cancer, which could end or limit the use of punishing chemotherapy for some patients.

The agreed price of $48 in cash is 62% above Array’s close last Friday -- already a record high. The company’s shares have soared thanks to drugs that target a mutation that’s found across a wide variety of tumor types, and could be used in treating a broad set of cancers in patients who carry the mutation. Array’s drugs, Braftovi and Mektovi, are already approved in the U.S. for use in advanced melanoma.
