Descrição
Inclusion Criteria:
- Diagnosis of metastatic breast cancer.
- Participants must have completed first line of metastatic chemotherapy and have achieved complete or partial response or disease stability for at least 6 months from the first confirmation of disease stabilization.
- No clinical sign of brain progression.
- At least one of the following 3 conditions: HER2 +++, Young age (< 50 years), and/or estrogen receptor (ER)-/progesterone receptor (PgR)-
- Eastern Cooperative Oncology Group (ECOG) performance status ≤2.
- Life expectancy ≥3 months.
- Neutrophils ≥1.5 x 10^9/L, platelets ≥100 x 10^9/L, hemoglobin ≥9 g/dL, lymphocytes ≥1 x 10^9/L.
- Bilirubin level either normal or <1.5 x ULN (upper limit of normal).
- AST (aspartate aminotransferase) and ALT (alanine aminotransferase) ≤2.5 x ULN (≤5 x ULN if liver metastases are present).
- Serum creatine <1.5 x ULN.
- Effective contraception if the risk of conception exists.
Exclusion Criteria:
- Concurrent chronic systemic immune therapy not indicated in the study protocol.
- Any investigational agent(s) within 4 weeks prior to entry.
- Participants that have completed 2nd, 3rd, or 4th line metastatic chemotherapy or participant in active chemotherapy treatment.
- Clinically relevant coronary artery disease or a history of a myocardial infarction within the last 12 months.
- Acute or sub acute intestinal occlusion or history of inflammatory bowel disease.
- Known Grade 3 or Grade 4 allergic reaction to any of the components of the treatment.
- Known drug abuse/alcohol abuse.
- Legal incapacity or limited legal capacity.
- Medical or psychological condition which in the opinion of the investigator would not permit the participant to complete the study or sign meaningful informed consent.

Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Number of Days With Progression-free Survival (PFS)
Prazo: 24, 38, and 52 weeks
|
PFS was defined as the time interval from randomization to objective tumor progression or death from any cause. The analysis could not be performed due to low enrollment. |
24, 38, and 52 weeks
|
|
Number of Days With Disease-free Survival (DFS)
Prazo: 24, 38, and 52 weeks
|
DFS was defined as the time interval from randomization to any relapse (loco-regional, contra-lateral, and/or distant). The analysis could not be performed due to low enrollment. |
24, 38, and 52 weeks
|
|
Number of Days With Distant Disease-free Survival (DDFS)
Prazo: 24, 38, and 52 weeks
|
DDFS was defined as the time interval from randomization to only distant metastases (for example, bone, visceral organ, brain). The analysis could not be performed due to low enrollment. |
24, 38, and 52 weeks
|
|
Number of Days With Brain Recurrence-free Survival (BRFS)
Prazo: 24,38, and 52 weeks
|
BRFS was defined as the time interval from randomization to the appearance of brain metastases. The analysis could not be performed due to low enrollment. |
24,38, and 52 weeks
|
|
Number of Days on Temozolomide Treatment
Prazo: Baseline to 24 Weeks
|
This outcome measure was only applicable to the temozolomide arm; the observation arm was therefore not analyzed.
|
Baseline to 24 Weeks
|
|
Total Dose of Temozolomide Taken
Prazo: Baseline to 24 Weeks
|
This outcome measure was only applicable to the temozolomide arm; the observation arm was therefore not analyzed.
|
Baseline to 24 Weeks
|
|
Number of Participants Who Had at Least One Dose Reduction During Treatment
Prazo: Baseline to 24 Weeks
|
This outcome measure was only applicable to the temozolomide arm; the observation arm was therefore not analyzed.
|
Baseline to 24 Weeks
|
|
Number of Participants Who Had at Least One Treatment Omission During Treatment
Prazo: Baseline to 24 Weeks
|
This outcome measure was only applicable to the temozolomide arm; the observation arm was therefore not analyzed.
|
Baseline to 24 Weeks
|
|
Number of Participants Who Completed the Third Cycle of Treatment
Prazo: Baseline to 24 Weeks
|
This outcome measure was only applicable to the temozolomide arm; the observation arm was therefore not analyzed.
|
Baseline to 24 Weeks
