BP-C1 in Short-term Treatment of Thai Patients With Metastatic Breast Cancer

October 3, 2019 updated by: Meabco A/S

A Randomized, Double Blind and Placebo Controlled Multicenter Study Comparing BP-C1 and an Equal Looking Placebo in Metastatic Breast Cancer Patients. A Phase IIB Study

The purpose of this study is to determine whether BP-C1 is effective in the short-term treatment of metastatic breast cancer patients who have previously undergone at least three lines of chemotherapy.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

BP-C1, solution for injection 0.05%, is currently being developed for treatment of patients with metastatic breast cancer with palliative intent.

Active substance of the product, which is a novel platinum-containing anticancer agent developed for intramuscular administration, is а cis-diammineplatinum(II) complexed with a polymer containing benzene polycarboxylic acids derived from lignin.

The amphiphilic characteristics of the polymer have resulted in a product with clear and significantly altered and improved properties compared to other platinum analogues, e.g. cisplatin, carboplatin and oxaliplatin.

BP-C1 preserves antitumour activity of its predecessors (e.g. cisplatin and carboplatin), additionally offering the following advantages that ensure favourable outcome of treatment of metastatic breast cancer patients:

  • injectable solution (intramuscular) does not cause injection site reactions; can be administered at home by a nurse or a patient;
  • has an improved pharmacokinetic profile;
  • demonstrates efficacy comparable to cisplatin and much higher than carboplatin (in-vitro; in-vivo data);
  • exerts an additional immunomodulatory activity.

This study is a randomised, double-blind, placebo-controlled, multicentre, phase IIb study in Thai patients with metastatic breast cancer. The eligible patients will be allocated (1:1) to either BP-C1 arm or Placebo arm and treated once daily for 32 days. The patients allocated to Placebo arm will cross over to BP-C1 treatment for 32 days when progression of the cancer will be documented and latest after 32-day treatment with Placebo. After 32-day treatment with BP-C1 the patients are invited to continue open-label treatment under protocol BMC2011-02.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change (%) in the sum of diameters of target lesions
Time Frame: baseline to Day 32 of treatment
Diameter of target lesions will be measured by computer tomography (CT) with contrasting using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
baseline to Day 32 of treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of target lesions
Time Frame: baseline to Day 32 of treatment
Number of target lesions per each patient will be evaluated by CT with contrasting. Number of target lesions at baseline and Day 32 of treatment will be presented in shift tables.
baseline to Day 32 of treatment
Treatment response
Time Frame: baseline to Day 32 of treatment

In accordance with RECIST v1.1 the treatment response will be classified as 'complete response', 'partial response', 'stable disease' or 'progressive disease':

Complete response (CR): disappearance of all target lesions. Partial response (PR): at least 30% decrease in the sum of longest diameters of target lesions, taking as reference the baseline sum of diameters.

Progressive disease (PD): at least 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum might also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions will also be considered progression.

Stable disease (SD): neither sufficient shrinkage to qualify for PR, nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.
baseline to Day 32 of treatment
Karnofsky Performance Status (KPS) score
Time Frame: baseline to Day 16 and Day 32 of treatment
KPS describes an outcome in 11 grades, starting as normal without complaints and evidence of disease (equals 100 as the best) and dead (equals 0) as the lowest. KPS score will be assessed every 16 days during 32-day treatment period.
baseline to Day 16 and Day 32 of treatment
Separate scores of the general questionnaire EORTC QLQ-C30
Time Frame: baseline to Day 16 and Day 32 of treatment
The EORTC QLQ-C30 is a general quality of life questionnaire for cancer patients. The questionnaire contains 30 questions. Three variables will be obtained from the EORTC QLQ-C30: the sum of scores C1 to C5 denoted as "Physical activity problem last week", the sum of scores C6 to C28 denoted as "Discomfort last week", and the sum of scores C29 and C30 denoted as "Health and quality of life".
baseline to Day 16 and Day 32 of treatment
Separate scores of the specific questionnaire EORTC QLQ-BR23
Time Frame: baseline to Day 16 and Day 32 of treatment
The EORTC QLQ-BR23 is a breast cancer-specific quality of life questionnaire. The questionnaire consists of 23 questions. Three variables will be obtained from the EORTC-BR23: the sum of scores BR1 to BR13 denoted as "Breast cancer problem last week", the sum of scores BR14 to BR16 denoted as "Sexual interest and activity last four weeks" and the sum of scores BR17 to BR23 denoted as "Breast cancer related pain and discomfort last week".
baseline to Day 16 and Day 32 of treatment
Maximum Common Toxicity Criteria (CTC) score
Time Frame: baseline to Day 16 and Day 32 of treatment
Maximum CTC score will be recorded using NCI Common Toxicity Criteria v2.0 divided in 15 categories.
baseline to Day 16 and Day 32 of treatment
Change in the Sum CTC score
Time Frame: baseline to Day 16 and Day 32 of treatment
The Sum CTC score will be a sum of all registered CTC scores by 15 categories.
baseline to Day 16 and Day 32 of treatment
Number of registered adverse events
Time Frame: baseline to Day 32 of treatment
Adverse events (AEs) will be coded according to the MedDRA (version 16.1E). AEs will be systemized by system organ class and by preferred term. AEs will be analyzed by severity, seriousness and relatedness to the drug.
baseline to Day 32 of treatment
