Potential New Adjuvant Tx for Stage II-III
Hello Ladies! I don't know if this has been discussed here already, but I thought this was news that ER+/HER2- Stage III ladies might like to be aware of.
Palbociclib Enters Adjuvant Testing for Stage II-III Breast Cancer
The article also includes a video with a doctor explaining more about the clinical trial and their hope for the drug.
For those who may not know, Palbociclib is a CDK4/6 Inhibitor which means it plays a role in stopping cancer cells from progressing to the proliferative phase. It is not a chemo or hormonal treatment. Based on previous and current clinical trials in the Metastatic BC setting, Palbociclib has been shown to prevent existing tumors from any further growth and in many cases causes regression of tumors. It more than doubles survival time in Stage IV, yet survival stats are still not complete because so many women in the Stage IV trials are still living.
As some of you know, I have been dealing with BC for over 14 years now. Was NED in Stage IIIC for over 8 years before becoming Stage IV this past March. I was fortunate to enroll in the Pfizer Palbociclib clinical trial in April. My only Stage IV tx to date has been the trial protocol. My mets spread was determined to be to lymph nodes in neck, chest and abdomen. The trial is specifically tracking 3 of my largest nodes in the abdominal area. After the first 2 months of treatment my scans showed a 33% reduction in the size of those 3 nodes. At the end of 4 months I have a total of 39% reduction of those nodes, plus no new lesions or areas of concern.
Pfizer has already applied for early FDA approval of Palbociclib which possibly will become publicly available in 2015. If the Dana Farber trial and others show positive results in their Stage II-III trials, this may become another adjuvant treatment option for Stage II-III women.
Here is the link to the actual Dana Farber trial info in Boston, in case any ladies are in that area. The trial indicates it is still recruiting. There is a detailed listing of inclusion and exclusion criteria.

P.S. I want to clarify that the clinical trial I am in is a double blind study, so neither I nor my research staff know for a certainty that I am getting the Palbociclib active drug instead of Placebo. I am for sure getting the Faslodex injections as standard of care, just as everyone else in the trial is getting. SO...it is possible that the good response I have experienced so far is due solely to Faslodex. Based on my current understanding of the anticipated SE's on Palbociclib, however, my educated guess is that I am on the active trial drug. My personal experience is anecdotal at best, the real data is in the final analysis of data from the completed trials. So it is always best to evaluate based on the scientific data. I just happen to have a personal opinion about my experience which may or may not be accurate.

Thank you SO MUCH for this very useful post. I appreciate the time and care you took, for all of us. It has seemed lately that all the new breakthrough treatments have been for Her2 positive. So nice to learn of something new for us hormone dependent Her2 negative stage three-ers.
This trial is something I have been looking for as my ace in the hole, for whenever...
Admiring you from afar, Weesa

Linda, thanks for posting and so glad to hear that you are doing well.
Can you tell us about the side effects of the drug?
-
Momine, here is an excerpt from Pfizer regarding the typical SE's in the Palbociclib/Letrozole combo used in the earlier trial:
"The combination of palbociclib and letrozole was generally
well-tolerated and the safety profile of the combination was consistent
with previously reported data. The most common adverse events in the
palbociclib plus letrozole arm were neutropenia (a decrease of the
neutrophil count), leukopenia (a decrease in the total white blood cell
count), fatigue and anemia. The neutropenia observed with the
combination in this study was non-cumulative and clinically manageable.
No cases of febrile neutropenia were reported in either arm of the
study. Neutropenia is an on-target, anti-proliferative side effect of
palbociclib and signifies inhibition of CDK4 and its effect on bone
marrow."As far as my experience, (please note the addendum to my original post indicating that I cannot know for certain that I am actually getting the Palbociclib since it is a double-blind trial), I have found the few SE's to be tolerable and mild at this point 6 months into the study. I have experienced fatigue which started out very mild, but which may possibly be accumulative since my perceptions are that my fatigue has increased over the almost 6 months. My WBC is now below the normal range and my Neutrophil count has hovered just below and slightly above the bottom range of normal but no where near being Neutropenia.
It is important to note that not all patients on the active drug, experience dramatic drops in blood counts. It has been posted that only about 30% of patients on Palbociclib experience significant drops in their lab work. For those patients, the drug dosage can be lowered and they are usually able to continue on the trial. I have also experienced a decreased appetite with subsequent weight loss, (not a bad thing for me), but it may well be due to the Faslodex injections since it is listed as a SE for that drug.
Having personally been through 2 separate BC dx which both required surgery, full chemo, radiation and anti-hormonals, I must say that there is no comparison between the numerous SE's I experienced then and the extremely mild, mostly negligible issues I am experiencing now on my current treatment protocol. **Remember however, the fact is "Your mileage may vary"!

Thanks, Linda!

fabulous news!
-
Linda, thank you so much. All your caveats are duly noted, although I tend to think you are in the treatment arm, given your results so far. It is always much better to hear real experience rather than reading an SE list. Thanks again.
-
I am so feeling like crap right now, so happy to hear good news that could help us all. thank you for posting this!!
-
Linda
I'm glad to hear you are doing well! Thank-you for posting this information. It sound promising. I'm also glad to hear there is something new for us ER+ Her2- .

Linda
This is so great to hear....but mostly thrilled for you that you are kicking cancer's butt!!!!

Hi Linda, So so happy to hear you are responding. Almost 40% reduction and no new lesions is awesome. These new targeted treatments are phenomenal! I wish you continued "reduction" and NED in your near future.
-
LindaLou....thank you so much for stopping by, we've missed you. So thankful you were able to participate in this exciting trial and for your great response! Thoughtful of you to come share this info with us. I love receiving this new info and the hope it brings us Her2- girls. Thank you and please stop by anytime so we can keep up with you!!
-
Sincere thanks to everyone for the good wishes! I will continue to bring personal updates to my Stage III family and certainly will share any new treatment news I come across that I think would be helpful here. I believe we are in an exciting and rapidly developing time in the area of cancer research. While there is still a long way to go, new treatment opportunities with improved effectiveness and better preservation of quality of life are being discovered. Lord willing, I plan to be here for a long time!

Great news feeling jealous, side effects really affect how well we can adjust to life post cancer.......
-
Always nice to hear from you thanks for the info I will take note and ask...that is how I got on Zometa my Onc had not heard of it ..when ever I read anything I bring it to her she must think Im nuts but don't care knowledge is power ...and LIFE !!
love n light Cheryl
