Hi,
My wbc was low most of the time I was on chemo. I was also getting the Neulasta shot every two weeks to boost my wbc. I also tried eating lots of good protein (chicken, eggs, fish) to help my counts. It might be that because he is on a research they can't give him the shot because it will change the data they are looking for. I would check with the lead doctor also to find out if that is the case. Also ask the doctor if he can get back on the study once his WBC is back up. What chemo is he on? Good luck.
