An Observational, Multicenter Study Evaluating the Safety of ReAl-lifePertuzumab and Trastuzumab Fixed Dose Combination: the RAPID Study

Completed

• Conditions: Breast Cancer

• Registration Number: NCT06835348
• Lead Sponsor: Fondazione Oncotech

Brief Summary

This is a single arm prospective, observational multi-centre study in patients with HER-2 positive breast cancer who have completed concurrent chemotherapy with pertuzumab and trastuzumab administered IV and are currently receiving or will be receiving maintenance therapy with PH FDC SC and have at least 6 cycles of therapy expected with PH FDC SC to conclude pre-established oncological treatment.

Treatment of the patients will not be determined or assigned by study procedures but will be based on normal clinical practice. Only data available per clinical practice will be collected within this study. The treatment decision must have been taken prior to and irrespective of patient's inclusion in the study.

Detailed Description
