         14 . The article of manufacture of  claim 5 , further comprising a package insert instructing the user to administer the fixed doses of pertuzumab and trastuzumab subcutaneously to a patient with HER2 positive cancer. 
     
     
         15 . The article of manufacture of  claim 14 , wherein the package insert instructs the user to co-administer the fixed dose pertuzumab and the fixed dose of trastuzumab subcutaneously as two separate subcutaneous injections.
