Treatment algorithm
• Multiple molecular alterations:- DNA alterations were considered of a higher impact than
hormone receptors expression
- If AR and ER/PR were both overexpressed, the hormone
receptor with the highest expression level was taken into
account
- If >2 DNA alterations were identified, clinically validated
alterations prevailed (i.e. HER-2 amplification)
- Erlotinib was not given in case of KRAS mutation

Is the current design of precision
medicine studies the right one? PRO1) The SHIVA trial asked a real-life question
2) The SHIVA trial was designed to evaluate a specific
prespecified treatment algorithm
3) The cross-over data of the SHIVA trial suggest that
taking each patient as his/her own control is a relevant
strategy for precision medicine studies

Conclusions
• The current design of precision medicine
studies is relevant
• Using the PFS ratio as a primary end point
might be a relevant strategy for precision
medicine trials
• Treatment algorithms will need to be
refined to further improve patients’ outcome
