Two New Drugs May Be Highly Effective In Breast Cancer

Two new drugs in pipeline for the treatment of breast cancer may be the magic bullet for breast cancer. Preliminary studies show that a combination of these two drugs is highly effective in killing cancer cells. Seventy five percent of breast cancer tumor cells in mice were killed by the combination. The new drug combination also suppressed the re-growth of tumors.

These findings were recently published in the journal Cancer Biology and Therapy. Researchers say that this may have implications for breast cancer, prostate cancer, lymphoma, myeloma and other hematologic cancers.

Paul Dent, Ph.D., associate professor of biochemistry and radiation oncology at VCU, led the team of researchers. In this new study, researchers combined two novel drugs, UCN-01 and a MEK 1/2 inhibitor, which are known to inhibit protein kinases, part of tumor survival signaling pathways.

"In addition to potently inhibiting cells and suppressing tumor growth, these drugs are also part of a modern class of drugs that are less toxic to non-cancerous cells," said Dent. "We are eager to move these exciting findings from the labs to patients."


When studied separately, the drugs only killed a small percent of the cells to which they were exposed. Combined, however, the result was quite startling.

"Within five days, we saw profound tumor cell death," Dent says.

Breast cancer
Every year, more than 200,000 women are diagnosed with breast cancer in the United States. Breast cancer ranks second as the leading cause of cancer deaths in American women. Until recently breast cancer topped the list of leading causes of cancer deaths in women, but lately lung cancer has claimed the top position. If skin cancer is excluded, breast cancer is the commonest cancer among American women.
