AstraZeneca, Merck in $8.5B Oncology Pact

AstraZeneca and Merck have entered a global oncology collaboration to co-develop and co-commercialize AstraZeneca’s Lynparza (olaparib) for multiple cancer types. Lynparza is an innovative, first-in-class oral poly ADP ribose polymerase (PARP) inhibitor currently approved for BRCA-mutated ovarian cancer in multiple lines of treatment.

Lynparza’s pipeline has grown significantly in the last few years, with 14 indications currently being developed across several tumor types, including breast, prostate and pancreatic cancers. The strategic collaboration is expected to further increase the number of treatment options available to patients.

The companies will develop and commercialize Lynparza jointly, both as monotherapy and in combination trials with other potential medicines. Independently, the companies will develop and commercialize Lynparza in combinations with their respective PD-L1 and PD-1 medicines, Imfinzi (durvalumab) and Keytruda (pembrolizumab).

The companies will also jointly develop and commercialize AstraZeneca’s selumetinib, an oral, potent, selective inhibitor of MEK, part of the mitogen-activated protein kinase (MAPK) pathway, currently being developed for multiple indications including thyroid cancer.

Merck will pay AstraZeneca up to $8.5 billion, including $1.6 billion upfront, $750 million for certain license options and up to an additional $6.15 billion contingent upon successful achievement of future regulatory and sales milestones.

"Our strategic collaboration builds on scientific evidence that PARP and MEK inhibitors can be combined with PD-L1/PD-1 inhibitors for a range of tumors," said Pascal Soriot, chief executive officer, AstraZeneca. "By bringing together the expertise of two leading oncology innovators, we will accelerate Lynparaza’s potential to become the preferred backbone of many immuno-oncology combination therapies as the world’s first and leading PARP inhibitor. This is a truly exciting step and we are pleased to work with Merck, a company that shares our passion for science to deliver new medicines for cancer patients."

Kenneth Frazier, chief executive officer, Merck, said, "This global collaboration between AstraZeneca and Merck, two oncology leaders, will increase the possibilities for patients to have more treatment options for more cancers. Merck continues to build its leadership in immuno-oncology with Keytruda as foundational in monotherapy and combination therapy, and this collaboration expands our oncology leadership into the growing targeted therapies of PARP and MEK inhibitors. We look forward to working with AstraZeneca to create greater value for patients and shareholders than if both companies worked independently."

AstraZeneca and Merck will share the development and commercialization costs for Lynparza and selumetinib monotherapy and non-PD-L1/PD-1 combination therapy opportunities. Gross profits from Lynparza and selumetinib product sales generated through monotherapies or combination therapies will be shared equally.

Merck will fund all development and commercialization costs of Keytruda in combination with Lynparza or selumetinib. AstraZeneca will fund all development and commercialization costs of Imfinzi in combination with Lynparza or selumetinib.

AstraZeneca will continue to manufacture Lynparza and selumetinib.
