Target-based therapeutic matching of phase I trials in patients with metastatic breast cancer in a tertiary referral centre.


ABSTRACT:

Background

Greater understanding of the molecular classification of breast cancer has permitted the development of rational drug design strategies. In a phase I clinical trial setting, molecular profiling with next-generation sequencing of individual tumour samples has been employed to guide treatment.

Methods

We conducted a retrospective evaluation of clinical outcomes of patients with metastatic breast cancer (MBC) treated in phase I clinical trials at our institution to assess the benefit of molecularly matched compared to non-matched treatments.

Results

A total of 97 consecutive patients with MBC were enrolled onto ?1 trial between 2009 and 2015. Fourteen patients participated in multiple trials, and a total of 113 trial encounters were reviewed in this retrospective study. Eighty-three percent of patients with molecular data available were able to participate in trials matched to molecular aberrations. Patients who were treated on matched studies had improved clinical benefit (RR: 1.80, p?=?0.005), progression-free (HR: 0.52, p?=?0.003) and overall survival (HR: 0.54, p?ConclusionsMolecular profiling for MBC patients in a phase I setting is feasible and aids therapeutic decisions with improved patient outcomes.
