KENILWORTH, N.J.: AstraZeneca and Merck & Co. Inc., known as MSD outside of the United States and Canada, announced that they have entered a global strategic 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.
Pascal Soriot, chief executive officer of AstraZeneca, said: “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. By bringing together the expertise of two leading oncology innovators, we will accelerate LYNPARZA’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 C. Frazier, chief executive officer of 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.”
Under the terms of the agreement, 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.
As part of the agreement, Merck will pay AstraZeneca up to $8.5 billion in total consideration, 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.
Merck expects to book its share of product sales of LYNPARZA and selumetinib, net of commercialization costs, as Alliance Revenue and its share of development costs associated with the collaboration as part of its Research & Development expense.
The collaboration agreement was completed upon signing on July 26, 2017.
LYNPARZA (olaparib) is an innovative, first-in-class oral poly ADP-ribose polymerase (PARP) inhibitor that may exploit tumour DDR pathway deficiencies to preferentially kill cancer cells. LYNPARZA is the foundation of AstraZeneca’s industry-leading portfolio of potential new medicines that target DDR mechanisms in cancer cells.
LYNPARZA is currently approved by regulatory health authorities in the EU for use as monotherapy for the maintenance treatment of adult patients with platinum-sensitive, relapsed BRCA-mutated (germline and/or somatic), high-grade serous epithelial ovarian, fallopian tube or primary peritoneal cancer, who are in response (complete or partial) to platinum-based chemotherapy.
It is also approved in the US as a monotherapy for patients with deleterious, or suspected deleterious, germline BRCA-mutated (as detected by a US FDA test) advanced ovarian cancer, who have been treated with three or more lines of chemotherapy.
The Company recently presented positive results for LYNPARZA from its Phase III OlympiAD trial that showed a statistically-significant and clinically-meaningful improvement in progression-free survival for patients treated with LYNPARZA tablets (300mg twice daily), compared to treatment with physician’s choice of a standard of care chemotherapy.
OlympiAD, a randomised, open label, multi-centre Phase III trial assessing the efficacy and safety of LYNPARZA in patients with HER2-negative metastatic breast cancer with germline BRCA1 or BRCA2 mutations, which are predicted or suspected to be deleterious, was the first positive Phase III trial to evaluate the efficacy and safety of PARP inhibitor beyond ovarian cancer.
LYNPARZA is currently being investigated in another separate non-metastatic breast cancer Phase III trial called OLYMPIA. This trial is still open and recruiting patients internationally.
LYNPARZA generated Product Sales in 2016 of $218 million.
Selumetinib, licensed by AstraZeneca from Array BioPharma Inc. in 2003, inhibits the MEK enzyme in the RAS/RAF/MEK/ERK pathway in cancer cells to prevent the tumour from growing. Selumetinib is in Phase III development for differentiated thyroid cancer, for which it was granted Orphan Drug Designation by the FDA in May 2016.
Selumetinib is also being tested in a separate Phase II trial in patients with paediatric neurofibromatosis type-1, and in a Phase I trial with patients suffering from advanced solid tumours.
