E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to determine the clinical benefit of the addition of bevacizumab to standard chemotherapy for previously treated metastatic breast cancer (MBC), as measured by progression-free survival (PFS), assessed in a two-step, hierarchical manner as described in the Protocol. |
L'obiettivo primario dello studio e' di determinare il beneficio clinico dell'aggiunta del bevacizumab alla chemioterapia standard per il tumore metastatico della mammella (metastatic breast cancer, MBC) precedentemente trattato, determinato come sopravvivenza in assenza di progressione (progression-free survival, PFS), e verificato con modalita' gerarchica come descritto nel Protcollo. |
|
E.2.2 | Secondary objectives of the trial |
- To estimate the clinical benefit of the addition of bevacizumab to each chemotherapy regimen, with PFS estimates and confidence limits calculated within each chemotherapy stratum for bevacizumab and placebo
- To determinate clinical benefit, as measured by objective response rate, duration of objective response,
one-year survival, and overall survival, of the addition of bevacizumab to standard chemotherapy options compared with standard chemotherapy alone
- To compare the incidence of toxicity, as measured by selected adverse events(see Protocol section 3.3.3) |
- Stima del vantaggio clinico dell'aggiunta del bevacizumab a ciascun regime chemioterapico,con valutazioni del PFS e limiti di confidenza calcolati all'interno di ogni strato di chemioterapia,per il bevacizumab e il placebo.
- Determinazione del beneficio clinico,misurato in base alla percentuale di risposta obiettiva,alla durata della risposta obiettiva,alla sopravvivenza a un anno,e sopravvivenza totale,dell'aggiunta del bevacizumab alle opzioni chemioterapiche convenzionali rispetto alla chemioterapia convenzionale da sola.
- Confronto dell'incidenza di tossicita',determinata in base ad eventi avversi selezionati (si veda Protocollo sez.3.3.3) |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subjects must meet the following criteria to be eligible for study entry:
• Signed Informed Consent Form
• ≥ 18 years of age
• Histologically confirmed carcinoma of the breast with measurable or
non-measurable metastatic disease that has progressed
Patients with a history of brain metastasis are eligible for study participation
(U.S. only), as long as their brain metastases have been treated and they have no
evidence of progression or hemorrhage after treatment and no ongoing requirement
for dexamethasone, as ascertained by clinical examination and brain imaging (MRI or
CT scans) during the screening period. CT scan with contrast or MRI scan of the
brain must be performed at least 3 weeks after completion of all therapy to the brain.
Treatment for brain metastasis may include the following: WBRT, SRS
(Gamma knife, LINAC, or equivalent), or a combination as deemed appropriate by
the treating physician. Radiotherapy and stereotactic radiosurgery must be
completed at least 4 weeks prior to Day 0.
Patients may also have neurosurgical resection. Neurosurgery must be completed
at least 6 weeks prior to Day 0, and brain biopsy must be completed at least
4 weeks prior to Day 0.
• Progression of disease during or following administration of one
(non-investigational) chemotherapy regimen, defined as single-agent
chemotherapy administered prior to or during disease progression or a
pre-specified combination or sequence of cytotoxic agents administered in the
first-line settingSubjects whose initial treatment changed prior to progression in the
first-line setting are ineligible unless the change occurred within 30 days
of initial treatment due to toxicity.
• ECOG performance status of 0 or 1 (see Appendix B)
• For women of childbearing potential, use of an effective means of
non-hormonal contraception
• Life expectancy ≥ 3 months
• Willingness and capacity to comply with study and follow-up procedures |
I pazienti dovranno soddisfare tutti i seguenti criteri di inclusione:
• Firma del Consenso Informato scritto
• Paziente di eta' ≥ 18 anni
• Carcinoma della mammella confermato istologicamente con lesioni metastatiche misurabili o non misurabili che siano in progressione
• Progressione di malattia durante o dopo la somministrazione di un regime chemioterapico citotossico convenzionale, definito come trattamento con chemioterapia ad agente singolo (single-agent chemotherapy) somministrato prima della progressione della malattia o come combinazione pre-determinata, o sequenza di agenti cito-tossici somministrati nella terapia di prima linea.
Quei soggetti la cui terapia iniziale e' stata modificata prima della progressione nel corso dell'adattamento terapeutico di prima linea, non sono elegibili per lo studio a meno che tale variazione sia avvenuta entro 30 giorni dall'inizio del trattamento iniziale, per motivi di tossicita'.
• ECOG tra 0 e 1
• Per donne in eta' fertile uso di un effettivo metodo di contraccezione non ormonale
• Aspettativa di vita ≥ 3 mesi
• Capacita' di soddisfare le richieste dello studio e le procedure di follow up |
|
E.4 | Principal exclusion criteria |
Subjects who meet any of the following criteria will be excluded from study entry:
a. Disease Treatment History
• Prior hormonal therapy only as treatment for metastatic disease
without chemotherapy. Patients must have received chemotherapy for their
metastatic disease in the first-line setting. Hormone therapy alone is not allowed.
• For subjects who have received prior anthracycline-based therapy,
documentation of left ventricular ejection fraction < 50% by either
multiple gated acquisition (MUGA) or echocardiogram (ECHO)
• Treatment with more than one prior cytotoxic regimen for MBC
• HER2-positive status
In general, HER2-positive status will be identified by a fluorescence in situ
hybridization (FISH) assay as evaluated at the institution or, if FISH is
unavailable, a 2+ or 3+ immunohistochemistry result (but the method of
identification may vary by region or institution). Patients who have unknown
HER2 status, and for whom determination of HER2 status is not possible,
are eligible for this study.
• Unknown ER and PR status
• Radiation therapy other than for palliation or brain metastasis, biologic therapy,
or chemotherapy for MBC within 21 days prior to Day 0
• Prior therapy with bevacizumab or other VEGF pathway-targeted therapy
See Protocol sec. 4.1.3 for:
b. Bevacizumab Exclusion Criteria
c. General Exclusion Criteria |
Soggetti che presentino i seguenti criteri saranno esclusi dalla partecipazione allo studio:
a. Storia del trattamento della malattia
• Precedente terapia ormonale solo come trattamento per le metastasi, senza chemioterapia
• Per soggetti che hanno ricevuto precedente terapia con antracicline, documentazione di frazione di eiezione del ventricolo sinistro < 50% tramite MUGA o ecocardiogramma
• Trattamento con piu' di un regime citotossico per cancro metastatico della mammella
• Pazienti con positivita' per HER2
• Pazienti con status ignoto per recettore degli estrogeni e del progesterone
• Radioterapia tranne come palliativo o per metastasi cerebrali, terapia biologica o chemioterapia per cancro metastatico della mammella entro 21 giotni prima del giorno 0
• Precedenti tepapie con bevacizumab o altra terapia VEGF pathway-targeted
