The third of many we will have.
I’ll give a bit of a recap. I know it gets quite technical but documenting the details is important for those who also have metastatic breast cancer.
It’s almost one year to the day that I was diagnosed with metastatic breast cancer in my bones and lymph nodes. I started on the cytotoxic daily drug Xeloda first (in addition to monthly infusions of Zometa) which gave me six months of success, shrinking the amount of cancer evident on PET scans.
In April 2013 when my tumor markers started rising I started on the hormonal combo of Aromasin and Afinitor (and also switched from Zometa to Xgeva because of difficult side effects I was having). I started on a 5 mg/day dose of Afinitor with a 25 mg dose of the Aromasin. I gradually increased the Afinitor dose to 7.5 mg/day, and then when my markers began to rise again a few weeks ago, I started on 10 mg a day.
It has now been five months on this combo (in all of its different dose strengths) and my markers are rising. This chemo is no longer working. So, it’s time to decide what to do next.
Regular readers will know that this is typical of metastatic breast cancer: some therapies may not work at all while some will work for a while. Ultimately, though, the cancer becomes resistant to each of these treatments and will progress. Sometimes you get a great response and can reduce the amount of cancer that is present. Oftentimes you settle for the success of “stability” where the cancer isn’t reduced, but it also isn’t growing. It’s often referred to as hanging out with “Stable Mable.” This is still a good response in most people’s books.
Especially when your cancer is still confined to your bones and lymph nodes, stability has the added feature of being life-saving: as long as the cancer is in those places it cannot kill you. Only once it metastasizes to organs can breast cancer kill.
So… now it’s time to decide what to try next (this part gets technical). Right now it’s looking like I’m headed to a clinical trial of a drug that has shown promise in breaking the resistance of hormone sensitive breast cancers especially in people like me whose cancer displays a Pi3k mutation (40% of people with ER+ breast cancer have one of these mutations). This experimental drug would be in combination with a drug commonly used for my kind of cancer (Faslodex). I’ve enrolled with the clinical trial team. This is a Phase II trial so I would be guaranteed to get the experimental drug.
What does this mean? In simple English, it means I’m trying a new drug that’s designed to break the resistance of this particular kind of cancer to treatment. It seems to be especially effective for those with the type of cancer mutation that I have (Pi3k-alpha). If this drug makes the cancer susceptible to therapy, then the other drug I’m taking can do its work. This class of drugs is at the forefront of where cancer research trials are right now.
I’ve been pre-screeened and have a few more hurdles to clear: scans, bloodwork, and a three week “washout” period where I must be chemo-free to allow any residual effects of my current treatment to clear. Am I nervous about a period with no safety net? Yes, a bit. But I also am curious how my body will react to having current chemo clear my system. I’ve had a lot of trouble with things like high blood pressure, high cholesterol, rapid heart rate, shortness of breath, and headaches in the past few months. I’m interested to see how many of these will improve.
The new drugs will have their own series of side effects, some of them might be similar and a few may be different and more serious. So this three week period sits okay with me because if my current treatment isn’t doing anything anymore, it’s of no use anyway.
There will be so much to share about being involved in a clinical trial. And I will share that with you, should I make it through the final screening process. I am learning so much as I go and I think there is a real chance here to inform others about the experience. Trials are as varied as can be. Each has criteria that must be met. Sometimes you end up on the good side of these and sometimes you don’t.
My oncologist looked at a host of trials before we chose this one. I was ineligible for many of them because of the drugs I have already tried, my particular features of my cancer, what cities the trials were offered in, when they were enrolling patients, etc. Some were not attractive to me because of the phase of trial that it was (I’ll explain in a separate post the differences between Phase 1, 2 and 3 trials). I am glad to be in a trial where a drug has already passed initial safety standards and will also be given to every patient in the group (there are no placebos in this phase of trial).
It’s important to note that a clinical trial should not necessarily be viewed as a “Hail Mary” meaning it’s the last remaining hope. In reality, my sense is that this is very rarely the case, at least with Phase 2 or 3 trials. They can only establish true efficacy in people who are still at certain phases of the disease process and haven’t had too many chemotherapy agents already.
To me the key was to find a trial that had a good scientific basis for success, was currently enrolling patients and was within commuting distance. In addition, I think it’s best if the standard of care drug is one you would already be considering using at this point in your treatment. There is a database at www.clinicaltrials.gov where you can search for trials.
I have reserved my spot in this trial. If I meet the testing criteria I will be one of 60 patients nationwide on this particular protocol, about 10 at my particular location. I view it as an opportunity. It is well-suited for my cancer at this time in treatment. It’s using the newest thinking in targeted therapy based on genomic analysis.
It’s scary, yes. But if it doesn’t work I still have standby treatments to go to (and other trials by that time that I hopefully would be eligible for). I know there is no cure. But maybe this one will give me a chunk of time.
I won’t go into details here but I know people will ask what’s involved. The treatments will be injections (Faslodex is two big intramuscular injections in the butt every month after doses every 2 weeks the first month) combined with daily oral capsule (the experimental drug). I will also continue to get an Xgeva injection in the arm each month. There will be a strict schedule of fasting bloodwork in NYC every two weeks and scans every 8 weeks to monitor the cancer’s growth. I’ll have to keep a medication diary. I’ll let you know how everything else works once I am underway. It’s a lot of work, especially in the first two months including all of the meetings and tests just to get started.
There are so many questions I know people will have. If you post your questions in the comments I will do my best to answer them in future posts if I can. You may post them anonymously if you like. For now I’m not going to state the name of the drug (actually just a string of letters and numbers) until I’m actually enrolled.
It was quite devastating to get the news that the current chemo isn’t working anymore. It always feels like the rug being pulled out from under me. I always cry. I always feel like I’m falling.
But plans are my safety net. Options are my lifejackets.
I leap from treatment to treatment on my tippy toes, knowing if I place too much weight I will sink.
This is the dance I do now. Forever.
