for the experimental lymphoma drug SGN-40, the companies announced Friday.

Rights to SGN-40, also known as dacetuzumab, will be returned to Seattle Genetics next June. Genentech made the decision to give up on the drug after a review of its drug pipeline, the company said.

SGN-40 is a humanized monoclonal antibody being studied in non-Hodgkin's lymphoma and multiple myeloma. In October, Seattle Genetics discontinued a phase II study of SGN-40 in B-cell lymphoma after independent trial monitors determined that patients were not benefiting from the drug.

Seattle Genetics' lead drug is brentuximab, or SGN-35, which is enrolling patients in a pivotal phase III study of Hodgkin's lymphoma.

Seattle Genetics' shares closed Thursday at $8.98.
