BP-C1 Monotherapy in Patients With Metastatic Breast Cancer Cancer: Estimation of Optimal Duration of Treatment

Metastatic Breast Cancer Clinical Trial

Official title: Estimation of the Optimal Treatment Duration and Cumulative Dose of BP-C1 in Breast Cancer Patients With Distant Metastases: a Dose-response Study (IC)

Status Completed

Clinical Trial Summary

The purpose of this study is to establish an optimal treatment duration and tolerable cumulative dose for BP-C1 in the treatment of metastatic breast cancer patients who had previously undergone at least three lines of chemotherapy.

Clinical Trial 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 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 an open-label, non-randomised, single-group, multi-centre study with a sequential safety design. The study consists of two parts: dose-response part and follow-up study.

Dose-response part: Patients who have completed the first 32-day treatment period with BP-C1 from Day 1 to Day 32 under Protocol BMC2011-1/Protocol MBC-BPC1/IIB or Protocol BMC2012-4, and having a maximum of "moderate" toxicity at the end of treatment are offered to continue in the second 32-day treatment period with BP-C1 from Day 33 to Day 64 under protocol BMC2011-02. Patients completing 64-day treatment period with BP-C1 will be followed up for 28 days.

Follow-up study: After 28-day follow-up period the patients without disease progression and without an increase in toxicity are offered to participate in the follow-up study. During the follow-up study the patients will be given BP-C1 as long as they obtain benefit from the treatment (i.e. until disease progression or increase in toxicity not above "moderate" grade). ;
