Brief Summary:
This is a phase I study to evaluate the safety and define the pharmacokinetic (PK) profile of orally administered reparixin in combination with paclitaxel in HER 2 (Human epidermal growth factor receptor-2) negative metastatic breast cancer patients.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: Paclitaxel+Reparixin Phase 1

Detailed Description:

The CSC (Cancer stem cell) concept has important implications for understanding carcinogenesis as well as for the development of cancer therapeutics. According to this concept, tumors are initiated and maintained by a cellular subcomponent that displays stem cell properties. These properties include self-renewal, which drives tumorigenesis, and differentiation (albeit aberrant), which contributes to tumor cellular heterogeneity. The existence of CSCs has been described in a variety of hematologic and solid tumors including those of the breast, brain, colon, pancreas, lung, liver, and head and neck. In addition to driving tumorigenesis, CSCs may contribute to tumor metastasis as well as to tumor recurrence after treatment.

One of the therapeutic strategies being pursued to target CSCs involves inhibition of self renewal or survival pathways in these cells. These pathways include NOTCH (Notch signaling pathway), Hedgehog, and WNT (Wnt signaling pathway). Such strategies may be limited by the role of these pathways in normal stem cell function, which could result in systemic toxicities from pathway inhibition. In addition to intrinsic pathways regulating stem cell functions, normal and malignant stem cells are regulated by extrinsic signals generated in the microenvironment or CSC niche. In the breast, this niche is composed of immune cells, mesenchymal elements that include fibroblasts, endothelial cells, adipocytes, and extracellular matrix components. These components play an important role in normal breast development and carcinogenesis. If the cellular microenvironment plays an important role in the regulation of CSC growth and survival, then strategies aimed at interfering with these interactions represent a rational approach to target breast CSCs.

There are limited data on the impact of treatment tailoring based on CSCs detection. Gene profiling of CSCs could lead to identification of therapeutic targets on CSCs (e.g. hormone receptors, HER-2 [Human epidermal growth factor receptor-2] expression, EGFR [Epidermal growth factor receptor] expression), and could represent tumor biopsy in "real time". Several groups showed frequent discordance of HER-2 status between primary tumor and CSCs, and case reports showed clinical utility to use of trastuzumab-based therapy based on HER-2 CSCs status. Similarly, the hormonal status of CSCs could be different from that of the primary tumor, which could lead to increase the number of patients suitable for endocrine therapy, but also could explain why endocrine therapy fails in a subset of hormone receptor-positive patients. The study provided the in vivo demonstration that CXCR-1 (Chemokine receptor 1) targeting with specific blocking antibodies or reparixin is associated with reduced systemic metastases. The experimental data provides another therapeutic target in metastatic disease and warrants a pilot study investigation in humans to further explore effects of reparixin on breast CSCs and the tumoral microenvironment.

Reparixin seems to be a good candidate for use in breast cancer patients because of its very acceptable toxicity profile shown in the Phase I and II clinical trials conducted so far, along with its observed activity in vitro against breast cancer cell lines and in vivo in tumor xenografts in mice. It potentially addresses another therapeutic target in metastatic disease. The current pilot study thus aims at exploring the safety and PK profile of orally administered reparixin in HER-2 negative metastatic breast cancer patients and its effects on breast CSC markers.
