Study of Ad.p53 DC Vaccine and 1-MTin Metastatic Invasive Breast Cancer

2014-08-27 03:16:53 | BioPortfolio


The purpose of this study is twofold. The first objective is to find the highest dose of 1-Methyl-D-tryptophan (shortened to 1-MT) combined with a vaccine called Ad.p53 DC that can be given safely to patients without causing severe side effects. The second objective is to see if 1-MT can help patients mount a better immune response to the Ad.p53 DC vaccine. Both of these treatments are experimental at this time.


The dose of 1-MT that patients take will vary depending on when they enroll in this study. This study initially studies how increasing amounts of the drug combined with vaccine affects the patient's body. The starting dose is 100 mg and will be increased in a step-wise fashion (200mg, 400mg, and 600mg) in order to find out what is the most effective dose without any major side effects. If the drug is safe and well tolerated in the starting dose group, then it will be increased for the next group of patients who are enrolled on the trial. The information obtained from the dose escalation part of the study (safety, immune responses) will be used to select one of these four doses of 1-MT to combine with the Ad.p53 DC vaccine. This is the Phase 1 part of the study. The Phase 2 part of the trial will enroll patients at the selected dose of 1-MT plus the Ad.p53 DC vaccine.

High Indoleamine 2,3-Dioxygenase Is Correlated With Microvessel Density and Worse Prognosis in Breast Cancer.

Indoleamine 2,3-dioxygenase (IDO), which catalyzes the breakdown of the essential amino acid tryptophan into kynurenine, is understood to have a key role in cancer immunotherapy. IDO has also received...

Adult weight change and the risk of pre- and postmenopausal breast cancer in the Chinese Wuxi Exposure and Breast Cancer Study.

The accumulating evidence indicates that weight gain in adulthood is more predictive of breast cancer risk than absolute body weight. However, the relative impact of timing of weight gain in adulthood...

Medical and Biotech [MESH] Definitions

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
