NCT01785030
Nitrous oxide (N2O) is a gas that is normally used to take away pain and anxiety during painful medical procedures. However, one of its effects is to also make veins appear larger and more visible. This is useful when there is a patient who needs to have an intravenous (IV) needle put in their skin to give them medicine or fluids, but may have veins that are very hard to see or feel. The mechanism of this observed effect is not entirely clear. The purpose of this study is to use an ultrasound to directly measure whether there is an actual change size of veins or change in blood flow in healthy adult volunteers when you give them 50% nitrous oxide, and see whether or not this change in size, or change in flow, is what causes the changes in visibility or palpability of the vein.
NCT01174368
This is a clinical research study of an investigational (FDA IND-BB 10091) treatment of subjects with castration-resistant prostate cancer resistant to Taxanes (docetaxel, cabazitaxel) and evidence of disease progression on androgen-axis inhibition and/or immunotherapy in the form of sipuleucel-T. The treatment is being evaluated for its effect on tumor growth. It consists of the placement (implantation) of small beads that contain mouse renal adenocarcinoma cells (RENCA macrobeads). The cells in the macrobeads produce substances that have been shown to slow or stop the growth of tumors in experimental animals and veterinary patients. It has been tested in 31 human subjects with different types of cancers in a Phase I safety trial. Phase II studies in patients with colorectal, pancreatic or prostate cancers are in progress.
