    It's nearly 2016, but this still appears to be the active Afinitor thread at bc.org

    Here's an interesting and related news story about its effectiveness, unwanted effects and FDA approval:

    Stephanie, thank you for the link to the Afinitor article. The article states that the drug may elicit formidable side effects and consequences, as follows:

    In the trial for advanced breast cancer, 63% of those taking Afinitor had to cut the dose of the drug or temporarily stop treatment. and nearly one in five developed a potentially fatal lung condition known as noninfectious pneumonitis... Since 2009, the year the drug first got on the market, there have been nearly 9,000 reports of serious adverse reactions among Afinitor users, including more than 2,700 deaths and more than 3,100 hospitalizations.

    (Certainly nothing to be taken lightly!)

    I hope you all don't mind me butting back in here even though I'm no longer on Afinitor. I read the article and it brings up good information about the potential side effects of Afinitor, but I sort of resented what seemed to me like a very sensationalistic tone.

    It's true that Afinitor has some bad potential side effects, but I think it's on the oncologist to discuss those and weigh them with patients, not for the FDA to deny approval for a drug that more than doubles PFS. It would be one thing if the side effects were covered up and people were being prescribed Afinitor before easier drugs without knowing, but I don't see that being the case here. I think most of us have already failed AIs, Faslodex, and, now that it's on the market, Ibrance, too. In this situation, it seems like the question is whether Afinitor is harder to take than chemo or whatever the other options on the table are, not whether it's harder to take than not having cancer.

    I'm not railing at you, Stephanie, I'm just frustrated that the article's authors seem to me to be so clueless about what having stage IV cancer is all about and what's really at stake here.

    Ok, rant over! :-D

    HI Anne,

    Thanks for your perspective on the article.

    I also posted it at

    And

    https://www.smartpatients.com/conversations/16992

    At the former, there were cautionary tales about bad experiences with Afinitor. At the latter site, there was still much enthusiasm for it, especially among those dealing with kidney cancer who often have advanced disease and very few viable treatment options. From my years of thinking about mTOR inhibitors (it's linked to my rare, genetic disorder), I appreciate that this is a "best" option for some and a "last ditch" or detrimental option for others.

    Hi RosesToes,

    I didn't take your statements personally at all! Similar situations in breast cancer treatment are Avastin and high dose chemotherapy with stem cell transplant. They were both treatments that started out the gate with great promise, but the adverse effects and lack of positive effects, including improvement in overall survival, led to their becoming less favored treatments...once accurate efficacy and safety data filtered in.

    Thanks everyone for welcoming me here. I've been listening as a silent member for years, but have protected my energy by not getting involved in another online cancer group. Now I really need to meet others dealing with ascites, cachexia and talking about dying and death.

    So grateful, Stephanie

    My tumor markers aren't cooperating. They are slightly rising which means (for me) that A/A isn't really working. Maybe enough to kind of keep the cancer in check, but not the result I was hoping for. My onc wants me to stay on it for another month and see how my markers are then and possibly do another PET. I had one done in Nov, there were somethings the radiologist said were false "positive" because they didn't show up on the regular CT. I just feel like something is brewing and it makes me nervous. My onc acknowledges how hard it is to be in this in between area........and some days I do Ok with it. Today was not one of those days. I am feeling overwhelmed with the holidays, and not coping well with the everyday life of having a family. They are my biggest joy. They are what gets me out of bed in the morning. I am so grateful for them but I feel like I am letting everyone down and I am a huge financial drain on my family. Tomorrow will be better, but today hasn't been easy.

    Hi to everyone new and old to this treatment and those who maybe havent had it yet.

    I appreciate the article and like to stay informed from multiple sources. I am glad it shares information I heard from my MO. When presented with choice of how to respond to recent progression, MO did remind me that the long term plan is to try everything. Afinitor has not. been too bad so far. But I do have new bone pain. (tumor markers dont. mean anything for me). Pain is not disabling so will wait for scan in Feb. unless pain gets worse.

    Star, so sorry for your low day. I do love/hate the holidays as I can become overwhelmed. I wish for you a good day tomorrow.

    hello, Star brightly shines, I share your sentiments. I started A/A 3 weeks ago on lowest dose. 2.5mg. After 1 week I had dry cough, after 2 weeks I was extremely tired, cough became productive. Dr wanted to admit me, but I refused, so affinitor stopped for now & started Zithromax. I also have had a hoarse voice for week now. I have read bad press on affinitor. 2 & half yrs ago MDA offered this combo, my MO back in Fl recommended against it, said my QOL would go down, & it would not prolong my life. New MO says she has seen good results w/A/A. My counts after 2 weeks went down significantly. It may be the holidays have me down too, but I just don't have good feeling about my present treatment.

    I've been on AA for 8 months and will have a PET scan on Monday. If everything is okay, I will start my 9th cycle then. I started on 10mg and had to dose reduce to 7.5mg (after a 2 week break) because my liver levels were rising rapidly. I just had blood work done last week and my liver levels were rising rapidly again so dose reduction to 5mg. I also have grade 1 pneumonitis (I never had a cough, a shady spot showed up on a scan), which is a bit frightening, but I am being closely watched by a pulmonologist as well as my oncologist. The pneumonitis did respond to steroids, so that is good news. They have all agreed that I can stay on the AA as right now the benefits are outweighing the risks. I find this drug to be really strange. At the beginning I had mouth sores, high blood pressure and a rash that was awful and would not go away for months. After being on blood pressure drugs for 2 months I was able to wean off them. The mouth sores just pop up randomly with no rhyme or reason. The rash went away after about 4 months. Now 8 almost 9 months in the mouth sores are back and so is the rash, ugh. The hardest hit has been my liver. My liver enzymes are over twice the high level of normal…and again the pneumonitis. So, I am hoping the PET still shows stable, but also wondering if my body needs a break from AA. Ironically the worst side effects I don't feel, I actually feel quite good!

    Hi all,

    I started AA month ago. My markers are up, a lot, and there is slight progression in the liver (seen on ultrasound). Do you think a month is enough for AA to work? Meeting with onc is next week.I have failed 4 lines of treatment for the past year and a half and right now I want this one to work with all my heart.

    Kiss77,

    The only reassurance I can give is my MO waited 4 months to scan me after starting A/A stating "we have to give it time to work". I had increased bone pain after 2 months but we waited. My scan last week showed stableSmile. My tumor markets are meaningless, so scans are all I have to check progression.

    I wish you peace

    Hi, all. New to the thread but not the disease. Stage IV since 2011, diagnosed with liver mets summer 2015. Gemzar/ carboplatin failed, cyber knife treated 5 cm tumor in liver we think, one month post cyber knife MRI showed three new liver mets. Trying afinitor/aromasin even though recent biopsies show er negative now. (Was strongly positive). Taking 10 mg day for three weeks now, I started out at 10 mg. day. Trying this for eight weeks and then new scans. Had dry lips/ mouth/ throat about two weeks in, managed with lip balm and lots of water

    I have the rash. I've had it for about a week and it does migrate. Taking Benadryl and lots of baths followed by plain moisturizing. Spoke with onc nurse this afternoon and she says keep doing what I'm doing and call her back Wednesday or Thursday and let her know if it is better or if it is worse. I hate rashes.

    Hi Sueper

    I had a rash after taking A/A . It was uncomfortable. I was instucted to do the same things that you are doing with two exceptions. I took claritin not benadryl, and MO gave me steriod cream for places that rash was the worst. I wish you quick healing.

    Abstract Disclosures

    Abstract:

    Background: Everolimus is effective for patients with ER+/HER2- metastatic breast cancer. In BORELO 2 trial, about the half of the patients were treated previously with less than two therapies and the sensitivity to the previous endocrine therapy was more than 80%. However, efficacy and safety of everolimus for heavily pretreated patients with metastatic breast cancer are unknown.

    Methods: From April 2014 to January 2016, 35 patients with ER+/ HER2- metastatic breast cancer were treated with everolimus in our hospital. Most patients received more than 3 endocrine therapies after recurrence. We examined their clinical backgrounds and outcomes.

    Results: The median follow-up time was 11.1 months. Forty-eight percent of patients had metastases in one organ, 28% in 2 organs and 24% in more than 3 organs. Twenty-four percent of patients had lung metastasis, 38% had liver metastasis and 42% had bone metastasis. Eighty percent of patients received more than 3 endocrine therapies after recurrence. Responses for more than 6 months to the previous endocrine therapies were confirmed in 32% of patients. Fifty-five percent of patients were treated with chemotherapy after recurrence.

    Complete response was obtained in 0% patient, partial response in 10%, stable disease in 59% and progressive disease in 14%. The median progression-free survival with everolimus treatment was 114 days. Seventy-two percent of patients had stomatitis (G3 18%), 17% had pneumonitis (G3 3%) and 21% had dermatitis.

    The reasons of discontinuation of everolimus treatment were disease progression in 61% patients, pneumonitis in 17%, stomatitis in 17% and others in 4%. Thirty-four percent of patients continued treatment with 10mg/day of everolimus until progression. Three out of 4 patients who discontinued everolimus treatment because of stomatitis had taken 10mg/day of everolimus. All the 4 patients who discontinued everolimus treatment because of pneumonitis had taken 10mg/day of everolimus.

    Conclusions: There was no significant difference of response rates, however, the progression-free survival with everolimus treatment was shorter than that in BORELO 2 trial. We may control the severe adverse events by reducing the dose of everolimus.

    Abstract Disclosures

    Abstract:

    Background: Stomatitis is a significant complication associated with mTOR inhibition. In BOLERO-2 patients (pts) receiving EVE/EXE, all grade (Gr) stomatitis was 67%; 33% had Gr ≥ 2 and 8% Gr 3. The median time to ≥ Gr 2 onset was 15.5 days, the incidence of new stomatitis (Gr ≥ 2) plateaued at 6 wks. In a meta-analysis, 89% of first stomatitis events occurred within 8 wks. Topical steroids are used to treat aphthous ulcers; anecdotal use as prophylaxis has been reported.

    Methods: Eligibility included PM women with HR+ MBC prescribed EVE/EXE. Treatment included EVE 10 mg and EXE 25 mg QD, with 10 mL of commercially available 0.5 mg/5 mL dexamethasone oral solution to swish x 2 min, and spit QID for 8 wks, starting day 1. Pts completed a daily adherence log, including an oral pain (range 0-10) and normalcy of diet score. The primary endpoint was to compare the incidence of Gr ≥ 2 stomatitis at 8 wks with BOLERO-2 results. Secondary endpoints included: MW use by average times/day, EVE/EXE dose intensity, incidence of all Gr stomatitis and time to resolution to Gr ≤ 1.

    Results: 92 women were enrolled; 86 are evaluable for efficacy. Median age was 61 yrs (range 34-87); 38% were treated with EVE/EXEin the ≥ 2nd-line setting. Median dose intensity was 10 (range 3-14) and 25 mg (range 8-25) for EVE and EXE. 95% of pts used the MW 3-4 times/day (median MW use/d = 3.95, range 1.9-4). The rate of ≥ Gr 2 stomatitis at 8 weeks was 2.4% (2 pts) with a Gr 1 rate of 17.4%; there were no ≥ Gr 3 events. A comparison of stomatitis incidence by grade between BOLERO-2 and SWISH is shown in the Table. Mean pain scale score was < 1 at all visits; 86% of pts reported a normal diet at 8 wks. 12% discontinued EVE/EXE due to suspected related adverse events (most common: rash [2%], hyperglycemia [2%], stomatitis [1%] and pneumonitis [1%]).

    Conclusions: Prophylactic use of 0.5 mg/5 mL dexamethasone oral solution markedly decreases the incidence and severity of stomatitis in patients receiving EVE/EXE for MBC and should be considered a new standard of care in this setting. Clinical trial information: NCT02069093

Lee Moffitt Cancer Center and Research Institute, Department of Women's Oncology, Tampa, FL

    Abstract Disclosures

    Abstract:

    Background: Everolimus is a sirolimus derivative that inhibits the mTOR (mammalian target of rapamycin) pathway. The BOLERO-2 trial showed improved progression free survival (PFS) with combined everolimus and exemestane versus exemestane alone in metastatic hormone receptor positive post-menopausal breast cancer patients. The initial dose of everolimus was 10mg and allowed for two dose reductions, 5mg daily and 5mg every other day. No data is available on PFS or toxicity for patients who were started, or dose reduced and maintained, on lower doses. We undertook a retrospective evaluation of PFS in patients with dose variations to determine if dose reductions adversely affect survival.

    Methods: Patients who were treated with the combination of everolimus and exemestane at Moffitt Cancer Center from April 26, 2012 - May 31, 2015 were obtained from our pharmacy database. A total of 138 patients met criteria consistent with BOLERO-2 patients. Chart review was performed to obtain data points.

    Results: PFS for the cohort as a total was 7.2 months. 77 patients were started on 10mg daily, 29 patients were started on 7.5mg daily, and 31 patients were started on 5mg daily. Dose reduction occurred in 47% of patients started on 10mg and 41% of patients started on 7.5mg. 22.5% of all patients discontinued treatment for toxicity, 75% of whom started on doses > 5mg. PFS comparison of starting 10mg to the average alternate dose (6.23 mg) was Hazard Ratio (HR) 1.15 (95% CI: 0.77-1.72) p = 0.49. PFS comparison of starting 10mg vs 7.5mg was HR 1.08 (95% CI: 0.65-1.80),p = 0.76 and starting 10mg vs. 5mg was HR 1.21 (95% CI: 0.76-1.95) p = 0.43.

    Conclusions: There was no significant difference in PFS between starting the recommended dose or a lower dose. Patients initiated on lower doses were less likely to require dose reductions or discontinue due to toxicity even with later dose increases. This data suggests that progression may not be limited by initiating lower, less toxic doses of everolimus. Therefore, if oncologists are more comfortable starting a lower dose, survival may not be adversely affected and patients may be more compliant, deriving a prolonged benefit from the combination.

    Abstract from Everolimus plus exemestane for hormone-receptor-positive, human epidermal growth factor receptor-2-negative advanced breast cancer: overall survival results from BOLERO-2†.

    Background: The BOLERO-2 study previously demonstrated that adding everolimus (EVE) to exemestane (EXE) significantly improved progression-free survival (PFS) by more than twofold in patients with hormone-receptor-positive (HR+), HER2-negative advanced breast cancer that recurred or progressed during/after treatment with nonsteroidal aromatase inhibitors (NSAIs). The overall survival (OS) analysis is presented here.

    Patients and methods: BOLERO-2 is a phase III, double-blind, randomized international trial comparing EVE 10 mg/day plus EXE 25 mg/day versus placebo (PBO) + EXE 25 mg/day in postmenopausal women with HR+advanced breast cancer with prior exposure to NSAIs. The primary end point was PFS by local investigator assessment; OS was a key secondary end point.

    Results: At the time of data cutoff (3 October 2013), 410 deaths had occurred and 13 patients remained on treatment. Median OS in patients receiving EVE + EXE was 31.0 months [95% confidence interval (CI) 28.0–34.6 months] compared with 26.6 months (95% CI 22.6–33.1 months) in patients receiving PBO + EXE (hazard ratio = 0.89; 95% CI 0.73–1.10; log-rank P = 0.14). Poststudy treatments were received by 84% of patients in the EVE + EXE arm versus 90% of patients in the PBO + EXE arm. Types of poststudy therapies were balanced across arms, except for chemotherapy (53% EVE + EXE versus 63% PBO + EXE). No new safety concerns were identified.

    Conclusions: In BOLERO-2, adding EVE to EXE did not confer a statistically significant improvement in the secondary end point OS despite producing a clinically meaningful and statistically significant improvement in the primary end point, PFS (4.6-months prolongation in median PFS; P < 0.0001). Ongoing translational research should further refine the benefit of mTOR inhibition and related pathways in this treatment setting.

    More on BOLERO-2 trial

    Mutations Tied to Outcomes in ER+ Metastatic Breast Cancer

    Free full text article from Medscape, registration required

    Excerpt:

    For patients with estrogen receptor (ER)-positive metastatic breast cancer (MBC), the clinical course can vary widely, with relapse occurring within months — or years.

    Predicting which patients achieve good disease control with single-agent hormonal therapy and which patients require more drugs for a durable treatment response is a significant clinical challenge.

    Now, a secondary analysis of archival tumor specimens from the BOLERO-2 clinical trial shows that two estrogen receptor α (ESR1) mutations — Y537S and D538G — are prevalent in patients with MBC who were previously treated with a nonsteroidal aromatase inhibitor (AI).

    Both of these mutations are associated with more aggressive disease biology and worse outcomes, say Sarat Chandarlapaty, MD, PhD, from the Human Oncology and Pathogenesis Program at Memorial Sloan Kettering Cancer Center, New York, New York, and colleagues in JAMA Oncology.

    The study results were first presented at the 2015 San Antonio Breast Cancer Symposium and reported by Medscape Medical News at that time.

    The full data report is now available, published online August 11.

    The analysis of noncell DNA from 541 patients with MBC that recurred and/or progressed during therapy with AIs revealed that 29% of patients (n = 156) had a mutation in the ER. These patients had a significantly shorter median overall survival than patients without a mutation (20.7 months vs 32.1 months).

    Importantly, prevalence of these 2 ESR1 mutations varied depending on whether the AI treatments were given in the adjuvant or metastatic setting. Patients in whom first-line therapy for MBC failed had a 3-fold increase in mutation prevalence compared with those initiating first-line treatment for metastatic disease (33% vs 11%), the study showed.

    "Overall, as a large suite of drugs (CDK4/6 inhibitors, HDAC inhibitors, PI3K inhibitors, new ER antagonists) are being developed for ER-positive MBC, assessment of ESR1 mutation status may prove to be a valuable predictive biomarker and ought to be incorporated in these studies.... The ease and affordability of such a test will also enable dynamic testing that will improve our understanding of the evolution of this disease and the design of strategies to improve outcomes," the authors write.

    How long can one be onthis combo before the cancer outsmart it. I have been on it for three months. Other than one episode to the A and E for gallbladder infection n removal, nine days in hospital, I have a decent quality of life with mouth sores and itchy pimples.

    Not sure if this thread is still in use. I'm looking to donate 2 packages of Afinitor that I can use. If anyone knows anyone who could use it, please send me a private message. If not. do you know what is the best way to dispose of it. Have received several conflicting ways. Thanks.

    highhopes,

    Offer it to your oncology office - they likely have indigent patients who can use unopened packages.

    Also, many pharmacies offer free "take back" programs. If yours doesn't ask who does in your region.

    My recycling center also directs patients where to take unused drugs.

    It's super-important that they not be flushed into water systems or dumped into garbage landfills, because they'll affect future lives and wildlife.

    This community reads like a bit of a ghost town, though plenty are still taking this combo. Many MBC & Stage IV folks have moved on to newer neighborhoods like Ibrance with Femara or Faslodex. Wouldn't it be nice to see a new header for it instead of one reading 2013?

    Warmest healing wishes for all, Stephanie

    I'll add to it, with the caveat that I'm a caretaker. My wife started on a trial with A/A and ribociclib after Ibrance/letrozole failed after only three months (not clear if it ever worked). She's been on it a week and side effects are rough, at least as compared to her previous treatments. Taxol (9/15-5/16) had almost none, but ovarian suppression along with the Ibrance/letrozole (5/16-8/16) created some abdominal pain. She also recently had the oopherectomy (she's only 32), so some of what I describe may be attributable to that as well--it's hard to tell. She's not only lost appetite, but feels that there is something that physiologically prevents her from eating more than a very small amount of soft food. She's had a bunch of abdominal nodal involvement, but the trial doctors think that it's probably irritation of her esophagus. She's also had night sweats (probably the menopause) and just general abdominal discomfort/bloating. She's being scanned again in only 4-5 weeks, so we'll see, but they don't think anything is actually creating a blockage somewhere in her digestive tract.

    Hi Batfax,

    You might want to add the peritoneal carcinomatosis community to your bco reads, since your wife has appetite suppression and abdominal bloating/discomfort and nodal involvement.

    It's at:

    Thank you. I'm a little concerned as her last CT revealed a "small amount of free fluid in the pelvis". Curiously, her MO didn't mention this despite noting progression in her liver, a new site in her Pancreas and a new small left pleural effusion. Also just saw after my last post that her CEA shot up from the already very high ~630 to ~900 in just about a month. Probably just further evidence of the Ibrance/letrozole failing as she didn't get to start the trial until last Friday.

    Batfax, double ouch!

    Do come to the Perioneal community as you'll get some good support and good advice for finding better care options.

    We're kinda geeky, but very kind. :)

    good healing wishes, Stephanie
