Abstract 116P
Background
In oncologic monotherapy, SC compared to intravenous (IV) route brings advantages like patients’ (Pts) and healthcare professionals (HCP) preference and improved healthcare efficiency, thanks to reductions of both time and use of resources.
Methods
During adjuvant dual blockade for HER2 EBC, trained observers measured time used in various treatment activities for 3 cycles (2nd to 4th) of pertuzumab (Perjeta or P) IV and trastuzumab (Herceptin® or H) IV or SC (Group A: P-IV+H-IV; Group B: P-IV+H-SC) and later for subsequent 3 cycles (5th to 7th) of PH FDC SC (Phesgo). The objectives were to assess time saved by Pts and HCP and what resources were used with PH FDC SC versus P-IV+H-IV or P-IV+H-SC.
Results
In 10 Spanish centres, 34 women were randomised (n=17 in Groups A and B). Per cycle, PH FDC SC saved 71% and 63% of Pts time in treatment room (-119 and -87 min, both p<0.0001) and 75% and 69% in chair (-121 and -90 min, both p<0.0001) compared with P-IV+H-IV and P-IV+H-SC, respectively. Active HCP time was reduced by 49% and 48% (-22.9 and -23.0 min, both p<0.0001), including preparation (-6.05 min p<0.0001 and -2.05 min p=0.1112) and administration (-16.9 min p=0.0006 and -20.8 min p<0.0001). Active times were reduced both for pharmacists (-2.10 min p=0.0185 and -1.46 min p=0.0488) and nurses (-18.3 min p=0.0004 and -20.0 min p<0.0001). PH FDC SC reduced use of consumables and avoided drug waste. Safety data up to cycle 7 (in 2025 ends 3-year follow-up) reported 20 Pts with 38 adverse events related to study treatments (only 2 Grade 3: diarrhoea and a serious [SAE] drug hypersensitivity).
Conclusions
PH FDC SC significantly saved Pts and HCP times and reduced use of healthcare resources. In dual therapies, the advantages of the SC route are added to those of fixed dose combination, versus administering drugs separately. Preliminary safety data indicated that the study treatments were overall well tolerated. Together with previous findings showing comparable efficacy and safety profiles and Pts preference of PH FDC SC versus P-IV+H-IV in (neo)adjuvant settings, these results encourage the use of PH FDC SC for dual blockade treatments.
