Beschrijving
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.

Secundaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Number of Days With Progression-free Survival (PFS)
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
