E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Dose-escalation cohorts (Phase 1b)
• To determine the maximum tolerated dose (MTD) and dose-limiting
toxicities (DLTs) of eribulin when administered in combination with
capecitabine in two different schedules in subjects with advanced and/or
metastatic cancer
Dose-confirmation cohort (Phase 2)
• To evaluate the efficacy of the combination of eribulin and capecitabine
when administered at the MTD (determined during Dose-escalation) in
the chosen dosing schedule from Phase Ib in female subjects with advanced
and/or metastatic breast cancer
|
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives
• To evaluate the safety, tolerability and toxicity profile of eribulin when given in combination with capecitabine
• To explore the pharmacokinetic (PK) profiles, including evaluating the potential for drug-drug interaction, of eribulin, capecitabine and capecitabine metabolites when eribulin and capecitabine are given in combination
Exploratory objectives
• To explore the pharmacokinetic/pharmacodynamic (PK/PD) relationship
between the combination of eribulin and capecitabine with neutropenia
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects in Dose-escalation cohorts (Phase 1b):
1) Histologically or cytologically confirmed cancer that is advanced and/or
metastatic
2) Resistant/refractory to approved therapies (defined as progressive
disease during or within 6 months after the last anti-cancer therapy) or
for whom single agent capecitabine at this dose level and schedule
would be a reasonable treatment option in the opinion of the investigator
3) Eastern Cooperative Oncology Group (ECOG) performance status (PS)
≤ 2
4) For subjects that previously received capecitabine all capecitabine
related toxicities must have completely resolved.
Subjects in Dose-confirmation cohorts (Phase 2):
1) Histologically or cytologically confirmed carcinoma of the breast that is
advanced and/or metastatic
2) Received up to three prior chemotherapy regimens in any setting
(sequential neo-adjuvant/adjuvant treatment counting as one regimen)
3) Chemotherapy regimens must have included an anthracycline (unless
anthracycline containing chemotherapy is inappropriate) and a taxane,
either in combination or in separate regimens
4) No prior treatment with capecitabine in any setting
5) At least one lesion of ≥ 1.5cm in longest diameter for non-lymph nodes
and ≥1.5cm in shortest diameter for lymph nodes which is serially
measurable according to the Response Evaluation Criteria in Solid
Tumors (RECIST) version 1.1
6) ECOG-PS 0 or 1
General inclusion criteria:
1) Adequate bone marrow function:
absolute neutrophil count (ANC) ≥ 1.5 x 109/L, hemoglobin ≥ 10.0 g/dL
(this may have been corrected by growth factor or transfusion), and
platelet count ≥ 100 x 109/L
2) Adequate liver function as evidenced by bilirubin ≤ 1.5 times the upper
limits of normal (ULN) and alkaline phosphatase, alanine
aminotransferase (ALT), and aspartate aminotransferase (AST)
≤ 3 x ULN (in the case of liver metastases ≤ 5 x ULN)
3) Adequate renal function as evidenced by calculated creatinine clearance
≥ 50 mL/min as per the Cockcroft-Gault formula or radioisotope
measurement |
|
E.4 | Principal exclusion criteria |
1) Suspected dihydropyrimidine dehydrogenase (DPD) deficiency
2) Prior participation in an eribulin clinical study, even if not assigned to
eribulin treatment
3) Pre-existing neuropathy > Grade 2
4) Subjects with brain or subdural metastases are not eligible, unless they
have completed local therapy and have discontinued the use of
corticosteroids for this indication for at least 4 weeks before starting
study treatment. Any symptoms attributed to brain metastases must be
stable for at least 4 weeks before starting study treatment; radiographic
stability should be determined by comparing contrast-enhanced
computed tomography (CT) or magnetic resonance imaging (MRI) brain
scan performed during screening to a prior scan performed at least 4
weeks earlier.
5) Electrocardiogram (ECG) with QTc interval > 470 msec |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint Dose-Escalation:
A dose limiting toxicity (DLT) is defined as any of the following toxicities considered to be
related to study treatment:
• Neutropenia Grade 4 that lasts ≥ 7 days
• Neutropenia Grade 3 or 4 complicated by fever and/or infection
(ANC < 1.0 x 109/L, fever ≥ 38.5°C)
• Thrombocytopenia Grade 4
• Thrombocytopenia Grade 3 complicated by bleeding and/or requiring
platelet or blood transfusion
• Non-hematological toxicity Grade 3 or higher (excluding Grade 3
nausea, and Grade 3 or 4 vomiting or diarrhea in subjects who have not
received optimal treatment with anti-emetic and/or anti-diarrheal
medication; also excluding any laboratory abnormalities without clinical
symptoms)
• Delayed recovery from treatment-related toxicity resulting in a dose
delay > 14 days
• Failure to administer ≥ 75% of the planned study drugs during Cycle 1
as a result of ≥ Grade 2 treatment-related toxicity that constitutes an
increase of ≥ 2 grades from baseline
The maximum tolerated dose (MTD) is defined as the highest dose level at which no more than one out
of six subjects experience DLT.
Efficacy:
Tumor response as assessed by the investigator will be based on RECIST
version 1.1 in all subjects. Tumor assessments (CT/MRI scans, photographs)
will be performed within 28 days prior to the start of study treatment and
every 6 weeks (within week 6) from first study drug dose. Bone scans will be
performed at baseline and every 18 weeks (within week 18) and at the time
of confirmation of response for breast cancer subjects in the Doseconfirmation
part of the study.
