Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Advanced breast cancer

Health condition(s) code:

Breast Neoplasms

Intervention(s):

Treatment will be provided in an ambulatory fashion, except the first and tenth hR3 administrations. After these two administrations, patients should be hospitalized for four days to facilitate sample taking for pharmacokinetic trial. All patients will receive chemotherapy and the doses level of MAb that correspond. Level 1: MAb hR3 (30 mg/m2) Level 2: MAb hR3 (60 mg/m2) Level 3: MAb hR3 (115 mg/m2) Level 4: MAb hR3 (230 mg/m2) MAb will be administered intravenously (antecubital vein), in 250 ml of saline solution in rapid infusion (30 minutes). Ambulatory chemotherapy is 4 cycles every 21 days (7th, 28th, 49th, and 70th day) compound by: -Doxorubicin (60 mg/m2) - Day 1 – 4 -Cyclophosphamide (600 mg/m2)- Day 1 - 4

Intervention code:

Antibodies, Monoclonal, Humanized

Doxorubicin

Cyclophosphamide

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Maximum permissible dose and/or optimal biological dose. Measuring time: 12 months

Key secondary outcomes:

Toxicity profile, pharmacokinetics, dose-dependent changes, systemic clearing variations. Measuring time: 12 months

Selection criterias

Section to complete information about the inclusion and exclusion criteria for participant selection, including age and gender.

Gender:

Female

Minimum age:

19 years

Maximum age:

None

Inclusion criteria:

1)Female patients with histologically confirmed breast cancer. 2)Patients with breast cancer, stage III or IV. 3)Patients should not have been on oncological treatment in the last 4 weeks prior to this treatment. 4)Age >18. Children are not included in the study because there are no data available in connection with adverse events and hR3 MaB dosage combined with doxorubicin and cyclophosphamide in patients under 18 years of age. 5)General condition ECOG <2 (Karnofsky >60%). 6)Life expectancy over 6 months. 7)Patient’s organs and bone marrow should be working normally, as defined by the following parameters: leucocytes >3,000/ul, absolute neutrophil count >1,500/ul, platelets >100,000/ul, total bilirubin within normal limits, TGO/TGP 60 mL/min/1.73 m2 on patients with creatinine values higher than the normal values established by the institution. 8)Patients with HER1+tumors (EGF positive receptor) determined by immunohistochemical techniques. 9)The effect of hR3 monoclonal antibody on human fetuses under development is unknown. Considering this and the fact that chemotherapy can also be teratogenic, reproductive age women should use appropriate contraceptive methods (barrier, hormone or abstinence) before and during the clinical trial. Reproductive age female patients should also be pregnancy-tested negative. If a patient gets pregnant or believes she is pregnant, she should inform her doctor immediately. 10)Capacity to understand the study and readiness to sign the informed consent document.

Exclusion criteria:

1) Patients on another product under research. 2) Patients with history of allergy attributed to chemical or biological compounds similar to hR3 monoclonal antibody or the chemotherapy used in the study. 3) Patients with uncontrolled intercurrent diseases, including active infections, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, and psychiatric or social diseases hindering adherence to clinical trial requirements. 4) Pregnant patients. 5) Breastfeeding should be discontinued upon inclusion in the clinical trial because of potential and unknown adverse effects on infants. 6) Patients with anthracycline contraindications. 7) Patients with brain metastasis.
