About this study

Official title: Pharmacokinetic, Pharmacodynamic and Interleukin Profile of Intramuscularly Administered BP-C1 in Women With Metastatic Breast Cancer. A Phase ID Study

This study is an open label, non-randomized phase I single-armed study in women with metastatic breast cancer (MBC) who have previously undergone all available standard chemotherapy regimens. The purpose of the study is to estimate the pharmacokinetics (PK) after single dose and multiple dose of BP-C1, investigate interleukin levels during BP-C1 treatment and assess treatment response according to RECIST criteria.

Read the detailed description

BP-C1, solution for injections 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.

In this study six female patients with MBC who have previously undergone at least third line therapy will be enrolled. Each included patient will participate in a screening period (maximum duration of 21 days) following by 32-day treatment period and 28-day follow-up period.

The patients will be treated with BP-C1(daily intramuscular injections) for 32 consecutive days. The study is undertaken to evaluate pharmacokinetics, pharmacodynamics and treatment effect of BP-C1.

Secondary outcomes (4)
  1. Interleukin Serum levels (Interferon γ and β, Tumour Necrosis Factor (TNF-α), IL-1beta, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-21 and IL-25)

    Measured: Day-1, Day 1, Day 16, Day 32, Day 34

  2. Change (%) in the sum of diameters of target lesions

    Diameter of target lesions will be measured by computer tomography (CT) with contrasting using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1

    Measured: baseline to Day 32 of treatment

  3. Number of target lesions

    Number of target lesions per each patient will be evaluated by CT with contrasting. Change in number of target lesions from baseline to Day 32 of treatment will be presented in shift tables

    Measured: baseline to Day 32 of treatment

  4. Treatment response

    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

    Measured: baseline to Day 32 of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BP-C1 in people with Metastatic Breast Cancer and Stage IV Breast Cancer, run by Meabco A/S at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Israel, Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Single-dose PK: Maximum Observed Serum Concentration (Cmax) for Platinum (time frame: Pre-dose, 10, 20, 30, 35, 40, 45, 60, 120 min and 6, 24, 48 hours post dose). The study lists 11 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2019.
