Inclusion criteria

Key Inclusion Criteria: 1. Subjects with confirmed diagnosis of recurrent or metastatic breast cancer based on histopathology examination 2. Subjects with diagnosis of HER2-negative breast cancer that was confirmed by IHC or in situ hybridization (ISH) assessment of tumor samples 3. Subjects who have received up to 3 lines of therapy for advanced disease, without prior exposure to taxane in the advanced stage setting 4. Subjects who have a performance status of ≤2 on the Eastern Cooperative Oncology Group (ECOG) scale. 5. Subjects who have measurable disease according to the Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST version 1.1). Key

Exclusion criteria

1. Subjects who have received prior taxane therapy in the metastatic setting 2.

Subjects with neuropathy grade ≥2 based on CTCAE v4.03 at the time of study entry 4. Subjects with symptomatic, untreated metastases to the central nervous system (CNS) at the time of screening. 5. Subjects who have received any investigational drugs or devices within 4 weeks before the first day of study treatment (C1D1).

Design outcomes

Primary

MeasureTime frameDescription
Objective Response Rate(ORR)Every 8 weeks upto 18 months from randomization dateORR is defined by Response Evaluation Criteria in Solid Tumors (RECIST) (v.1.1) criteria

Secondary

MeasureTime frameDescription
Progression free survival(PFS)Up to 18 months from randomization datePFS is defined as the time from date of randomization until the date of first documented progression or death.
Overall survival(OS)Up to 36 months from FPIOS is defined as the time from the date of inclusion to the date of death.
Time to treatment failure(TTF)Up to 18 months from randomization dateTTF is defined as the time from the randomization date to the date of discontinuation of treatment, regardless of the cause.
Quality of life(QoL)after randomization(C1D1), D1 of every 3rd cycle(each cycle consists of 28 days) up to 18 monthsEvaluate changes compared to baseline using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
Disease control rate(DCR)Up to 18 months from randomization dateDCR is defined as the percentage of subjects who were evaluated for complete response(CR), partial response(PR), and stable disease(SD) as the best response among from randomization.
PKThe 12 eligible subjects will receive DHP107 and be taken blood samples for PK analysis on Day 1, 8 of Cycle 1Pharmacokinetics is defined as the study of the time course of drug absorption, distribution, metabolism, and excretion.
Duration of response(DOR)Up to 18 months from randomization dateDOR is the time between the initial response to therapy and subsequent disease progression or relapse.
