Clinical Trial Summary

The purpose of this study is to increase survival of patients with early and locally advanced triple-negative breast cancer adding selumatinib to standard preoperative chemotherapy regimen.

Description:

Molecular analysis of residual tumor after administration of neoadjuvant chemotherapy revealed several mechanisms of resistance to treatment. High frequency of RAS-RAF-MEK-ERK signal pathway activation was found in cells of triple negative breast cancer after neoadjuvant chemotherapy, which correlated with high proliferation index and low pathological complete response rate. Thus, inhibition of MEK molecule - an intermediary transducer of this pathway may decrease activity of this pathway and restore tumor sensitivity to cytostatic agents.

Hence, the use of SELUMETINIB, an oral selective inhibitor of MEK1/MEK2 kinases, in combination with Docetaxel should increase pathological complete response rate and in turn increase survival of patients with early and locally advanced triple-negative breast cancer.

• Age: over 18 years;

• Eastern Cooperative Oncology Group (ECOG) score: 0-1 points;

• Left ventricular ejection fraction (LVEF) based on Echocardiogram (ECHO) or Multigated radionuclide angiography (MUGA scan): >55%

• Laboratory values before the study start must meet the following criteria:

• Negative serum pregnancy test for women with childbearing potential or evidence of a post-menopausal status (total cessation of menses for more than 1 year. The following age-specific requirements must also apply:

• Women < 60 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more. The levels of Follicle-Stimulating Hormone (FSH) and estradiol must also be in the post-menopausal range (as per the institution).

• Women = 60 years;

• Simultaneous participation in other clinical studies;

• Presence of acute or active chronic infections or other conditions (e.g. unstable or uncompensated respiratory, cardiac, hepatic, or renal disease, active bleeding diatheses or renal transplant), that in investigator's opinion may interfere with the treatment described in the study protocol;

• Have refractory nausea and vomiting, chronic gastrointestinal diseases (e.g., inflammatory bowel disease), or significant bowel resection that would adversely affect the absorption / bioavailability of the orally administered study medication

• History of another neoplasm (with the exception of adequately treated basal cell or cervical cancer in situ and cases when a cancer has been in remission for 5 years of more)
