After 12 weeks on Cabozantinib (XL 184) things are going OK. I wish I could say GREAT, but I am also not complaining!
I started the trial on August 30th with a 25 mg dose. During the first 6 weeks I didn't notice any side effects, however I did notice an increase in bone pain in several locations. On October 11 I had the first required follow up bone and CT scans. The results of those scans showed a 20% improvement in the overall state of the bone mets. While good, the trial was looking for 30% or greater.
On November 1st my dose was increased to 125mg. This dose was determined per the trial requirements. We were concerned about that high of a dose. [At this time I was on both 2 10mg Oxycontin and 6-8 325mg Oxycodone daily]. The increase in the trial drug coupled with the constant struggle with constipation from the pain meds, made for a rough beginning on the month.
After trying multiple over the counter laxatives, I finally got a prescription variety that started working right away. On the flip side, after six days on the higher dose of the trial medication, I was experiencing nausea that was unbearable at times. The doctor suggested I stop taking the medication for three days until the constipation and nauseas was fully relieved and then a smaller dosage would be suggested.
With both the nausea and the constipation under control, I started the trial meds again on November 10th at a new dosage level of 75mg. The following twelve days were spent readjusting the pain meds, laxatives, etc., and I was able to go back to Boston for my November 21st scans and doctor appointment on the 22nd. At the appointment on the 22nd the doctor showed me a side by side comparison of the October 11th and the November 21st bone scans. Even with my untrained eyes I could see a difference, and it was encouraging! There were a few smaller tumors that had cleared up completely and most others had noticeable reductions in size.
75mg may still be too high, I still have occasional nausea issues. I'll stay on top of this over the next few days and talk to the doctor if it continues. We are trying to work around a limited appetite and I am suffering from fatigue. I have lost about 12 pounds. The best news is that I have not had Oxycodone in almost 48 hours. Sleep is getting better but there are still some nights that are rough.
Happy Holidays everyone, peace be with you all!
