 Docetaxel is the standard, first-line chemotherapeutic agent for castrate resistant prostate cancer. While it has clinically useful activity, there is a strong need for substantial improvement in its efficacy. Possible ways for improving docetaxel monotherapy would be to combine it with an agent that either minimized toxicity thus allowing higher doses or improves efficacy by targeting synergistic pathways. Lycopene is an attractive agent for combination with docetaxel because of its known accumulation in prostate tissue, its low toxicity, and its ability to inhibit signaling through the IGF-1 axis, and to reduce IL6 levels. Lycopene is highly synergistic with docetaxel at inhibiting the growth of prostate cancer in mice. The purpose of this study is to determine the maximum tolerated dose MTD of lycopene given in combination with docetaxel. This dose can then be used for subsequent phase II or phase III studies.
