Changes to Intervention(s)
 
CIMAvax-EGF group (Experimental). The patients will receive 8 administrations of the product. Every administrationwill have a dose of 2.4 mg of the active principle of the therapeutic vaccine CIMAvax-EGF® (rhEGF-rP64k conjugate) in 1.2 mL of the injection (vaccine in aqueous phase plus Montanide ISA 51 VG) intramuscularly. The total dose will be divided into 4 subdoses, equivalent to 0.6 mg of EGF at each site of inoculation (both deltoid regions and both glutes). During the induction phase they will receive 4 administrations, one every 14 days. They will then receive 4 doses during the maintenance phase, one dose every 28 days, until 6 months of treatment are completed.
