Overview

Open-label Study of Safety, Tolerability and Pharmacokinetics of Multiple Doses of BI-CON-02 in Patients With HER2-positive Metastatic Breast Cancer, Previously Treated With Trastuzumab

Status:
Terminated
Trial end date:
2017-06-05
Target enrollment:
0
Participant gender:
Female
Summary
This study will evaluate the safety and tolerability of BI-CON-02 in patients with HER2-positive metastatic breast cancer, previously treated with trastuzumab The clinical trial protocol for BI-CON-02 prescribes a start dose of 0,3 mg/kg. After the Data and Safety Monitoring Committee evaluates the data of tolerability and safety of BI-CON-02, received during 3 weeks of investigational product therapy (Week 3, Day 1) and approves, extra doses can be used. Once the safety of investigational product is confirmed, the dose will be increased in the subsequent cohorts. Planned doses - 0,3 mg/kg; 0,6 mg/kg; 1,2 mg/kg; 2,4 mg/kg; 3,6 mg/kg and 4,8 mg/kg.

Criteria
Inclusion Criteria:

To participate in the clinical study, patients must comply to the following criteria:

1. Signed patient's information sheet and informed consent form to participate in the
study

2. Females aged ≥ 18 years

3. Histologically confirmed diagnosis of locally advanced or metastatic breast cancer.

4. HER2-positive tumor status by results of immunohistochemistry (IHC3+) or hybridization
in-situ (ISH), received at the local laboratory, experienced/certified to determine
HER2 expression by means of accurate and validated methods.

5. Disease progression during or after trastuzumab-based chemotherapy.

6. Previous chemotherapy on metastatic breast cancer.

7. Requirements for laboratory parameters determined below:

Hematology: Absolute neutrophil count:

Platelets:

Hemoglobin: ≥ 1500/mm3 (1.5 x 109 cells/L)

- 100 000/mm3 (100 x 109 cells/L)

- 9.0 g/dl

Liver function: Total bilirubin:

Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkalinephosphatase
≤ 1.5 x ULN

≤ 2.5 x ULN or ≤ 5.0 х ULN in case of liver and/or bones metastasis Renal function:
Serum creatinine or GFR (according to Cocroft-Golt formula): ≤ 1.5 mg/dl > 60 ml/min

8. Patients must have an ECOG status of 0, 1 or 2

9. Women of childbearing potential (not sterile or in menopause less than 2 years) must
be practicing an effective method of birth control during the whole period of the
study and 6 months after the last administration of the investigational product.
Effective methods of birth control include usage of a condom or diaphragm (barrier
method) with spermicide.

Exclusion Criteria:

The patient will be considered ineligible for the study in case she has any criteria listed
here below:

1. Clinically significant cardiovascular diseases:

- Myocardial infarction within 6 months before screening

- Unstable angina within 3 months before screening

- Congestive heart failure Class III or IV according to the New York Heart
Association (NYHA) criteria

- Clinically significant ventricular arrhythmia, that have to be treated, including
ventricular tachycardia, ventricular fibrillation, history of cardiac arrest

- QTc interval > 460 ms (ECG) (calculated according to Fredericia formula), or a
diagnosis of long QTc syndrome

- Ejection fraction of left ventricle ≤ 50% (EchoCG)

- Hypotension (systolic arterial blood pressure < 86 mm of mercury) or bradycardia
with a heart rate of < 50 beats per min., except when caused by medications (e.g.
beta-blockers)

- Uncontrolled arterial hypertension (systolic arterial blood pressure > 170 mm of
mercury or diastolic arterial blood pressure > 105 mm of mercury)

- Troponins I ≥ 0.2 ng/ml

2. Patients with known cerebral metastases or clinical signs of cerebral metastases.

3. Patients with severe dyspnea at rest, or those who need additional oxygen therapy in
everyday life.

4. History of hypersensitivity to trastuzumab ≥ 3 severity level

5. History of any toxicity related to trastuzumab administration that resulted in the
termination of trastuzumab therapy.

6. Peripheral neuropathy ≥ II severity level

7. Bisphosphonate therapy for symptomatic hypercalcemia.

8. Any chemotherapy, hormonotherapy, radiotherapy, immunotherapy or biological products
therapy used for breast cancer treatment within 4 weeks before the first
administration of the investigational product.

9. Previous indication of doxorubicin in maximum cumulated dose > 360 mg/kg2, or its
equivalent.

10. Participation in other clinical studies or administration of other investigational
products within 4 weeks before the first administration of the investigational
product, or presence of on-going toxicities ≥ II grade according to CTCAE, related to
any prior antitumour therapy (excluding alopecia).

11. History of other malignancies with the exception of cervical carcinoma in situ or skin
basal-cell carcinoma, that had undergone surgical removal and treatment within ≥ 5
years before the first administration of the investigational product.

12. Presence of antibodies to human immunodeficiency virus (HIV), or hepatitis С virus
(HCV), presence of HBsAg

13. Active infection within 4 weeks before the first administration of the investigational
product.

14. Uncontrolled concomitant diseases and conditions, including mental or social, which,
in the Investigator's opinion, may prevent the patient from participation in the
study.

15. Drug or alcohol abuse on the moment of screening or in the past, which, in the
Investigator's opinion, makes the patient unsuitable for participation in the study.

16. Pregnant or lactating women, or women who plan to get pregnant during the clinical
study

17. Inability to read or write, unwillingness to understand and comply with the procedures
of the study protocol, as well as any other concomitant medical or serious mental
conditions, that make the patient unsuitable for participation in the clinical study,
limit the validity of informed consent receipt or may affect the patient's ability to
participate in the study.
