We had high hopes for the heavy duty chemo that Warren has been on for two months, but despite that, all of his tumors showed growth since the last CT scan. The good news is we won't have to start the next series of the chemo next Monday. They have two other protocols currently available and he will start one of those in about four weeks time. In the meantime he's agreed to participate in a Phase "O" (zero) study which is not intended to be therapeutic but rather informational. He'll get one dose of a drug to test whether his tumor expresses a certain enzyme and whether or not the drug suppresses that enzyme. If it does that would bode well for further study on that drug. In fact one of the studies coming up would use that drug in combination with another. Tomorrow he'll go for a biopsy for the Phase Zero study and Sunday night he'll be admitted to the hospital, get the drug and a second biopsy on Monday, and will come home on Tuesday morning 24-hours after receiving the drug.
