Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This will be a proof of principle clinical trial to evaluate the use of pasireotide (SOM230) in women with ductal carcinoma in situ (DCIS) of the breast. Surgery and radiotherapy are used as treatment for DCIS and subsequent treatment with antiestrogens has been effective in reducing the occurrence of invasive breast cancer. Unfortunately, treatment with antiestrogens carries potential serious side effects and toxicities that are intolerable to some patients. Preliminary data suggest that inhibition of IGF-1 action in the breast will be at least as effective as tamoxifen. Pasireotide is a somatostatin analog that prevents mammary development by inhibiting IGF-1 action directly in the mammary gland and also indirectly without causing menopausal symptoms. This study is an expansion of work that we have previously done in women with atypical hyperplasia of the breast, which showed that treatment with pasireotide for 10 days caused a reduction in the cellularity of these precancerous lesions. In our present study, women with DCIS will be treated with pasireotide for 20 days prior to surgical excision. Endpoints will be as follows: 1. To determine whether pasireotide will inhibit cell proliferation and angiogenesis (signs of tumor growth), and stimulate apoptosis (cell death) in surgically excised tissue in comparison to core biopsies from women with estrogen receptor (ER) positive DCIS. Both the core biopsy and surgical excision are standard of care procedures that women with DCIS have regardless of participation in this trial. 2. To use dynamic contrast enhanced MRI to assess patients before and after treatment with pasireotide and evaluate for changes in tumor volume and other tumor related features 3. In our previous study we found that many women experienced a slight elevation in blood sugar with 10 days of treatment with pasireotide. Other work has shown that this effect often resolves with greater duration of treatment. We are therefore expanding the duration of treatment in this study to 20 days to assess if the initial hyperglycemia seen with pasireotide improves as treatment duration progresses.
