According to AZ Lynparza’s potential uses have grown inin the last few years, with 14 indications currently being developed across several tumor types, including breast, prostate and pancreatic cancers.
The companies will develop and commercializeLynparzajointly, alone and in combination with other potential medicines.

Pascal Soriot, CEO, 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. He added, “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.”
