    This is really interesting! Has anyone here used Nerlynx? I'll have to do some more research but I completed Herceptin about a year ago, wonder if I'd be eligible for it? I'll have to read more about it and ask my oncologist!

    Thanks KB870! That was very helpful. I just emailed my doc about it!

    I've read some info about this drug, and it states that it is approvedfor early stage cancer. I was triple positive, stage IIIB, and finished herceptin 4 months ago. Does anyone know if stage IIIB is considered early stage? I think I've read that IIIB and C are not considered early stage. Not sure how the drug manufacturer is defining early stage.

    Hi cross_fingers:

    The following is not a statement about what is or is not included in the term, but is only my layperson view that Stage IIIB may be included in this case.

    I agree that "early stage" may mean different things in different contexts. I do not see a clear definition of how the term is being used in the FDA label for neratinib (Nerlynx). A possible suggestion that the meaning of the term here may differ from other situations includes the broad reference to "Stage III" in the FDA label, rather than a particular substage(s).

    In addition, the inclusion criteria for the ExteNET trial on the clinicaltrials.gov website indicate that patients "through" Stage "IIIC" were included in the study population.

    I do not have a copy of this, but the full-length trial publication and/or Supplementary Material available on-line might include more details if you have access or can purchase full access:

    >> Chan (2016): "Neratinib after trastuzumab-based adjuvant therapy in patients with HER2-positive breast cancer (ExteNET): a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial"

    >> http://thelancet.com/journals/lanonc/article/PIIS1470-2045%2815%2900551-3/fulltext

    Regardless, it would be worth making an inquiry with your team to ensure you receive accurate information from a professional. Because there may also be timing considerations, please promptly contact your Medical Oncologist to discuss whether this may be an appropriate option for you to consider.

    Hi all, I actually worked on the ExteNet study , and enrolled a number of patients on it. The criteria was early stage as defined by stage I through stage III..

    If anyone has any questions, I will be happy to share as now the trial is completed and the results are public

    lkc,

    I read a summary of the study and it said that 40% of the Nerlynx recipients suffered from "severe diarrhea." Were most of the affected patients able to control that diarrhea? How was "severe diarrhea" defined?

    Thanks for any insights you can offer!

    This appears to be addressed by Antidiarrheal prophylaxis. For more, see for example, the section "Dosage and Administration" and the section "Warnings and Precautions" at page 1 of the current FDA label:

    https://www.accessdata.fda.gov/drugsatfda_docs/label/2017/208051s000lbl.pdf

    By the way, the inclusion criteria were amended several times during the course of the trial, somewhat muddying the waters for the layperson. In addition, in general, the inclusion criteria and the ultimate approved indications may or may not be coextensive, depending on exclusion criteria and the actual data available for various groups or sub-groups.

    I would encourage those interested to consult their Medical Oncologist.

    yes, diarrhea was the most common side effect. The study was amended to add a regimen to prevent diarrhea once the patient started the drug.

    There was a also an allowance to dosedown depending on the severity of the diarrhea.

    I was just talking to my sister about this drug since she works for the mfr, and they are so excited to get it released! Because they are a small co and don't have their name out there yet, please discuss this with your MO. This sounds huge for Herceptin users!

    lkc --did this study include subcentimeter node negative patients? I am grateful that i had subcm ddisease but what I found was that women like myself were excluded from almost every single her 2 agent study --except for the APT study ( a phase II study ) , there isnt any study that has included this population, so wondering if this is even a question to raise with my oncologist

    the particular non metastatic study included women who finished their BC treatment and did not have any residual disease.

    The purpose of the trial was todetermine if this med prevented recurrence.

    KB870,

    From my searching, it appears that there is an approved patent in Canada for the "Treatment Regimen Utilizing Neratinib for Breast Cancer" http://www.ic.gc.ca/opic-cipo/cpd/eng/patent/27557...

    but there is no reference to Nerlynx / Neratinib on the Health Canada site, either on the Approved Drugs list:

    https://health-products.canada.ca/dpd-bdpp/dispatc... (enter 'Nerlynx' as the Product Name or 'neratinib' as the active ingredient)

    or on the Drugs Under Review list:

    https://www.canada.ca/en/health-canada/services/dr...

    That's all I can find, so it might be that the manufacturer has not yet submitted Nerlynx to Health Canada for approval. Someone else might know more.

    lkc - i was reading that Nerlynx was much more effective on Hormone positive patients. Is there any detail on how much more effective it is for those of us who are triple positive? I was diagnosed Stage II, negative nodes and had a pathalogic complete response to the neo adjuvant TCHP treatment. My MO said my recurrence risk right now is about 20% so i'm trying to find out how this might impact that number.

    Thanks!

    Ho, hum. Just sitting here waiting to get my pathology report... and in trying to decipher all the little abbreviations under everyone's posts mean I have come to realize that some of you with relatively recent diagnosis are getting Perjeta and some are not even factoring out size, nodes, stage, etc. And so I'm wonderingly how come

    My MO mentioned this to me last week. He wants me to start soon. I am four months out from my last Herceptin treatment and he says it is perfect timing. I will be his first patient taking this. In fact, I think I will be the first in this regional cancer facility. I'm a little nervous but I know I will take it as soon as it gets approved bymy insurance. Has anyone else started this?

    Hi Lkc and thanks for the offer. I read a few articles and watched a few (On live) videos about the trial that led to the FDA approval of neratinib. One of the conclusions, I seem to recall is that the difference in DFS survival, with or without, is minimal, especially for hormone- negative HER2 bc. Do you have the data on that?

  • lkc
    lkc Member Posts: 182
    edited August 2017

    The DFS rates revealed 93.9 for the study drug and 91.9 for placebo.

    And to amend my earlier remarks er pos women did have better responses then er neg.

    Note needs to be taken that the response rates were not stratified depending on the stage at enrollment.

    Hope this helps.

    So, I looked at the results and it seems like DFS is WORSE for HR negative folks. I wanted this, even with the poop fits, so bad. Are the side effects worth it for HR- people? Anyone know? Ikc?

    Please let me know if I'm reading this chart right. DFS at 24 months: 95.8 for 1-2 years out from Herceptin and 95.7 for Placebo. Does this mean that there really isn't any benefit if you're farther out from Herceptin treatment?

  • lkc
    lkc Member Posts: 182

    pez gal, yes the DFS w better for the hormone pos particiipants, BUT the hormone neg were not that far behind.

    And yes Mommato, you are reading the chart correctly.

    her2 BC tends to recur quite quickly so, the longer you are out the better the prognosis.

    No easy answers , I am afraid.

    hi, I was the first one to start this drug outside of the clinical trials. The one pharmacy that carries it told me this when they fed exed the drug to me. I began 8 days ago. I was stage 3, ER+, IDC. I finished Herceptin October 2016.

    I started a Facebook group called Nerlynx (Neratinib) support group. Please join if you start the drug. I have had some mild side effects so far. Thanks. Christine

    I was in the clinical trial for this drug, and I always suspected I was in the placebo arm since I didn't have any side effects (my onc eventually confirmed this.) We participants had a thread here - search Neratinib Clinical Trial and you can read through the posts discussing the side effects. Never before or since have I been so jealous of people having issues with diarrhea! Winking
