We arrived at UC Davis at 9:30 and were met by a vet student who took Xan’s history and did an exam to see if he would qualify for the research study that uses both IV and inhaled chemo. She then took our records and xrays to go over everything with the researcher, Carlos Rodriguez. They came back about 30 minutes later. Dr. Rodriguez said that Xan was the “ideal candidate” and then told me more about the study. A lot of information, but the main points were:
- Study is to benefit dogs and kids with OS
- He’d like to enroll 19 dogs and has 6 so far
- IV ifosfamide every three weeks (administered in 15 minutes, but will also give him 5 liters of fluid over 6 hours and some form of protectant)
- Inhaled gemcitabine to be administered by me at home twice a week for 45 min-60 min – this has to be done outdoors, I wear a “bug mask” and Xan wears a clear bag over his head that is hooked to a nebulizer and he breathes it in through the bag.
- This will go on for 6 months!!!
- Average survival rate 8 months (when the inhaled chemo was given alone in an earlier study it only gave the dogs a 75 day survival rate because it still metastisized and no chemo was given to treat the other parts of the body)
- Dogs have tolerated this really well, with very few side effects. Does not appear to harm the lungs.
- I have to pay for the ifosamide every time and xrays every other session
- I can’t stay with him for the 6 hours because of university policy (an owner had an accident and the university stopped the practice of owners staying with their pet…), he will be in a small x- pen in the main room where he can be monitored.
My reservations:
- Putting a plastic bag over Xan’s head (although I put it on him for 10 seconds and he didn’t object) and wearing a bug mask
- Xrays every 3 weeks
- 6 months of chemo
- I was given zero paperwork or details about the study (although I admit that I didn’t think of this until after I left) – not sure if studies are usually so informal?
If I decide to go for it, he is to report on Monday at 8am for his first IV treatment. Does anyone have thoughts about or experience with doing this level of chemo for 6 months? Meaning, is it going to effect Xan’s quality of life so much that the last 6 months of his life will be crappy? I want to do what is best for Xanadu, not what is convenient for me. So if this is his best shot, I am all for it.
we’ve never hear of this type of chemo – might be a good thing for the call-in tripawds radio show to discuss. the plastic bag over the head thing sounds scary to me, but then we’ve been know to be a bit skiddish with new things. paws crossed this will work and give you guys more quality time together. you’ll make the right decisions.

Hi Charon,
This is a trial that we are considering. It was trialed last year on its own, and while it killed the lung tumors, it didn’t prevent the disease from metasticizing, which is why this study combines traditional IV chemo with the inhaled chemo. It is really interesting and has great potential for both dogs and kids.
I am loooking into other ways to administer it, without using the bag. Xan has a large head and it is quite snug on him. I think the bag is the worst part about this trial.
Thanks for your comments!

Hi Xan
Interesting option. I feel like such an old-timer just because I can remember people looking at inhaled therapy about 1&1/2 yr ago – a long time by tripawds standards, but hopefully that will change for dogs in the future.
Do a search in the archives for two of the tripawd All-Stars: Tika (Tikanni) from Omaha who pulled all stops and ended up doing an inhaled form of chemo at home (I believe it was in the kitchen, although that seems unlikely when I think about it). At the very least, I promise the descriptions will entertain you!
Someone else was enrolled in the Davis study and I believe it was Caira Sue. I seem to recall the point you made: it worked on the lungs but not elsewhere, although I do remember Caira Sue having lung mets (maybe I have the wrong dog). If I am wrong about the dog, I believe this was between August and November 2009.
Did you search ‘inhaled chemo’?
Hope this helps. (My history only goes back to mid-July 2009).
Thnaks for posting these details! It’s sharing info like this that is the reason we started the Tripawds Blogs. Please keep us posted on how it goes.
