    OCTANE
    Ontario-wide Cancer Targeted Nuclear acid Evaluation

    My Onc invited me to take part in the OCTANE clinical study. Of course I said yes!

    OCTANE is another study to provide biomarker data from targeted gene sequencing.

    I told her I had already participated in POWER (London, On) and BIODIVA. She said that things could change as you move along in your journey so it may be worthwhile to do it at this point.

    I had to give two vials of blood when I was there this week to get the application started. They are going to see if there is enough archived tissue to sample from my last biopsy. I had two for the trial I just completed so I'm hoping they can grab something from one of those. They will know in 2-3 weeks if there is enough archived tissue to send for this study. If not, when I progress, they will ask for a fresh biopsy sample from one of the progressing tumours.

    Once the tissue samples are submitted, it will take 2-3 months to get the results.

    @GloHo I appreciate your ongoing willingness and commitment to all these trials!!

    @Alwayslearning

    Thanks. This is my third biomarker study. If they offer it, I will participate.

    The more information we have and the better informed we all are…the better for us to know what options are out there and to make informed decisions.

    It's unfortunate the timeframe for results for these biomarker studies is so lengthy. In that regard, if anyone is thinking about doing it, sooner is better.

    The catch is whether or not you have enough archived tissue. If not, in addition to blood samples, you will be required to undergo a biopsy for a fresh tissue sample.

    My experience with biopsies, I've had four, has been positive with only one of the biopsies causing me some discomfort.

    All of my biopsies have been for trial purposes…we just asked for more samples while I was undergoing the procedure so they could be sent out for the biomarker studies.

    So, if you are thinking about participating in a trial, some but not all require a biopsy. This is an ideal time to speak to your Onc about registering for a biomarker study. And, since you will likely be receiving treatment for the trial, the time it takes to get the biomarker results is not really an issue. It will help guide your next steps.

    Now, having said all that, my results did not identify anything out of the norm for OC…so nothing for targeted therapy.

    Also, your initial biopsy report will identify different markers that were found in your sample. The pathologist will usually(?) do a staining/immunostaining test to identify markers for your cancer. Each of my reports has come back with some of the same markers but also different ones. So, if you haven't already done so and are interested…pull up that initial pathology report and take a look.

    As always, whenever I discuss these biomarker studies, I have to caution that genetic markers are also reported. So, if something comes back positive, you will have to decide whether or not you're going to share the info with family members - they may be "at risk." A genetic counsellor is usually provided to assist you in working through the results and assist you in making your decision  

    Oh boy…there I go again!! This post was a lot more than I had intended to write 🤣 .

    @GloHo thank you for sharing all your trial experience as I will be hading this way, I think. My problem is that with a clear cell there are actually not many trials out there. Interesting to see that you participate in som many biological trials, and I was not offered one at PMH - maybe again different tumor? I discussed with my Onc the fact that Elahere - which I think is the new rescue drug when you are carboplatin resistant - is coming so late to approval in Canada while other countries already have it available for patients. This is a systemic problem in Canada and so frustrating when your tumor survival is so time sensitive- drug access for patients is always late. This is why I actually don’t understand that OC Canada does not allow other OC patient’s voices to be heard in their gathering of insights. I did fill out the service and expressed my anxiety looking forward. Sad to know that they may remove my piece.
    GloHo but your story is hopeful. It appears that while OC may not be curable, it can be managed and it seems you have found a really good path through it. My Ca125 was also rising (2nd surgery and C+P after recurrence in Jan 24 after dx in Feb23) but my CT last week was completely clear- yeah! I have chatted with my surgeon about it and she also felt that my bike accident last Nov with ongoing hip pain (accident was not so big but caused big hematoma on my buttock) could explain the rise in Ca125. Good to know. So, please keep informing about the trials and your trial experience. I find this really helpful.

    Hi@Tanja

    First…so very happy to hear that your last scan was clear! That is definitely great news! You must be over the moon to have received this news. Enjoy! 

    Now, the promising news about Elahere…from what I've read…Elahere is being prescribed for clear cell!! However, patients must be FRa positive and have received 1-3 prior types of chemotherapy. 

    This is what is on the Elahere website about determining FRa status: 

    Before you start treatment, your doctor will test a sample from your tumor to confirm that your cancer is FRa positive.

    Your doctor may be able to use tissue from an earlier biopsy or surgery for testing.

    Now, this brings me back to my discussion about the larger biomarker studies…if you want to participate in one of the extensive biomarker studies (if one is available for you), this is the time to speak to your Onc in order to get additional tissue samples while you are undergoing this biopsy procedure. 

    Thank you for letting me know that journaling about my trial experiences has been of interest to you.

    I do a lot of research, self-advocate and am very active in decision-making for my care. I am very fortunate to have had health care teams that have been so understanding, open to discussions, and have offered the best advice at each stage of my journey. 

    I think if you were able to get through the survey then your voice will be heard. I didn't get past the first question so I have no idea what insights they are looking for.

    I totally agree that the process for approval in Canada is too far behind other countries! So very frustrating!!

    @GloHo I chatted with my Medical Oncologist at PMH about determining the folate receptor alpha to see if I were to be eligible for Elahere, should the tumor recur. She told me that this test is not available in Canada yet and only comes with approval of Elahere. For all the others reading this, there is the option to go for second opinion to another country and they may offer you to test your tumor for more biomarkers. It does costs but this is somewhat affordable.  I guess, however, once you know, e.g. that you are positive for FRa then you really want the drug.

    @Tanja

    After reading the criteria for Elahere, I was disappointed that I will not be eligible. Which makes me wonder why my Onc mentioned it to me. An oversight? Not thinking about criteria? I will have a further discussion about this with her for sure.

    It is my understanding that if you meet the 1-3 prior treatment and other criteria and want to be considered for Elahere, you would have to undergo a biopsy to determine your FRa status. Personally, I would rather wait until it is available in Canada to get the testing.

    I just discovered that there is an Ocular Toxicity clinical trial for Elahere (Mirvetuximab Soravtansine) being conducted in Montreal. Although the measures are for ocular events and outcomes (not specifically for Elahere outcomes) you would be receiving the drug Elahere and would undergo the FRa testing. 

    🤔 Now, this has me thinking…if I have no other options when I go back in April, I will ask about doing this trial.

    Questions to ask my Onc

    Is the 1-3 treatment criteria in effect because it is for Elahere?

    Is this a timed trial - for a specific amount of time only?

    I will not be eligible for the drug when it is approved - is there a workaround?

    There are, of course, some cons in relation to travel and accommodation requirements as well as the related expenses if I were to participate in this trial. 

    Gives me something to think about over the next couple of months! 🤣

    This also makes me wonder why all of these biomarker studies don't start including markers for these new targeted therapies that are emerging. 😵‍💫
