iwCLL 2013: Dr. Jeff Sharman Discusses Two Issues: 17p deletion and Residual Disease in CLL
He reminds us about how thin and immature the data is when looking at 17p deleted patients treated with either idelalisib or ibrutinib, but, and it is a big but, how encouraging it is compare to the historical data. In other word, how much much better it is than standard therapy such as FCR.
Another take away message is when we are comparing studies, make certain we are comparing apples to apples. Results with treatment naive patients will be much better than that with a group of patients who had been a round the block a few times.
And sometimes the enemy of good is better. His advice is sound and I echo it. Most of these new drugs are a great leap forward in CLL therapy. At least for now when not one of the new oral meds is yet approved for CLL, don't be too picky about which one you can get. Do your homework, follow the literature (or my blog and other reliable online sources), check clinicaltrials.gov, and make the jump if appropriate.
Dr. Sharman also raises the question implicit in the observation that those treated earlier, before we are badly beaten up by chemo-immunotherapy or by the disease itself, do much better. Should we treat with these new agents earlier? Only more trials will tell.
And he has an interesting historical take on the issue of the residual disease.
Here I might respectfully differ with the doctor. These drugs work so differently than traditional chemo or even monoclonal antibodies, that we may need to radically rethink our assumptions about what residual disease means in terms of prognosis.
I personally hope so. My next CT will be 21 months after I first swallowed a bruton tyrosine kinase inhibitor named at that time PCI-32765, soon better known as ibrutinib or now as Imbruvica. My nodes have changed little in the last few CT scans with gut nodes hanging around 4 centimeters, so the risks associated with residual disease are not a theoretical problem for yours truly. I may have reached my "maximum response", but maybe that is not such a bad thing. Again, only long term follow up with inform us.
Here is Dr. Sharman. Please see his other videos if you haven't already. Lots of good stuff in this segment.
Part 7 soon, and more interviews to come.
On a personal note, thank you all for your kind thoughts and prayers as I battle this nasty respiratory infection.
I think I have hit bottom, and am clearly getting better, albeit slowly with levaquin 500, a broad spectrum antibiotic, aboard. I am hardly well, but I am no longer getting worse. My fear of pneumonia is fading.
