My Liver Cancer Blog

my first blog, a way for me to process my experience of being diagnosed with cholangiocarcinoma

I am a professor at a Canadian university. I’m married, have close relationships with my family, love my 2 dogs, love travel, and enjoy hiking (but day hikes only – not really into the hut-to-hut thing). I really hope I can get through this and do some major hikes again in the future. Thank god I also love reading novels (literary prize winners, but also espionage, detective, and sometimes Sci-fi). And thank god I live in an era of excellent tv. And thank god I love writing. There are many things I can still do that I love, even having cancer and being more home-bound than I would like to be.

If you’re new, I recommend starting with How I Found Out.

So, I’ve been very reluctant to share the precise information about how much Zeno costs. I think this reluctance comes from the upper middle class WASP in me: don’t talk about money, don’t talk about how much you paid for something, don’t talk about what you can and cannot afford. I’m embarrassed at how much we are paying for this drug.

But, my husband responded less enthusiastically to my previous post about my first infusion and the private clinic, and eventually he told me that he thought that I had left out one of the most important aspects of this experience, something that is fundamentally integral to the experience, and that is the outrageous cost per dose of this drug. In fact, he was furious — not at me; rather, at the cost of the drug, at the fact that the manufacturer can get away with charging so much, that neither the Ontario health care system nor our insurance company will pay for it. He said that by not being open about the cost I was being one of Foucault’s “docile subjects” — tacitly cooperating with the governmental/pharmaceutical system to discipline me into silence, allowing my embarrassment to stop me from speaking the truth about the cost and the fact that right now the only way to get the drug is to pay for it myself. (We are academics, so we occasionally call each other things like “docile subjects”).

I was still reluctant, but I agreed to talk to my therapist about it. And my therapist is not a WASP, and when I explained the issue and my embarrassment, she said, “You MUST, MUST, MUST share this information.” She agreed with my husband that by staying silent about the cost I was letting the government and the drug manufacturer get away with a lack of accountability to cancer patients. And she said I needed to be open about this, and get over my own cringing embarrassment, not only for myself, but for other patients, especially future patients, who I might be able to help by exposing the current cost of a life-saving drug. “How do you think breast cancer drugs became more accessible and affordable?!,” she asked impatiently, “by staying silent?”

So, the cost per dose of zenocutuzumab is $35,200 (US$25,750), and the protocol is a dose every 2 weeks. Yes, you read that right.

Are you shocked? Well, yes, you should be. It is shocking. I don’t know how the drug manufacturer justifies this — I guess they assume that insurance companies are paying for it, not patients themselves, and mostly they are marketing it in the USA, where it would be insurance companies that are paying for it. And, I imagine they must tell themselves that they need to charge this much to recoup R and D costs. And, knowing that the patient consumer base for this drug is very small (primarily a tiny subset of pancreatic and non-small cell lung cancer patients whose tumours happen to have the NRG1 fusion mutation), they must think they need to charge an exorbitant amount per dose to make a profit.

And, in this particular case, it probably doesn’t help that the company that has the commercial rights to market and sell Zeno in North America (Partner Therapeutics) is very, very small. It is not a large pharma company with deep pockets that might be more willing and able to donate or subsidize the drug or simply charge less per dose to begin with. You can tell just by looking at their website that they are small. They seem to market and sell only 2 drugs. I wish some bigger, richer company would buy them out today. (Or at least that’s what I think I wish. I also feel like I don’t know enough about how all this works to be sure that it would benefit me personally if they were bought out by a big, rich company.)

And my husband and I can’t really afford this. We can afford it for a few months, but after not too long we would have to re-mortgage the house, and our retirement savings would be gone. You might wonder why I have gone down this road at all if I might have to stop taking the drug in a few months. First, as I think I’ve said in previous posts, the literature about this drug says that it can be very effective. I am, in fact, incredibly lucky. Approximately 50% of patients with cholangiocarcinoma don’t have mutations driving their tumours for which there are any drugs. If first line treatment doesn’t work, they don’t have many options. My tumour has a mutation that is both very rare (less than 1% of cholangiocarcinoma patients have it) and “highly actionable” — that is, Zeno exists, and when it works, it works very well, not just keeping tumours stable, but shrinking them. (Shout out to my oncologist who is a researcher, as well as a clinician. He has published about “precision oncology” — that is, treatment based on specific tumour mutations — being where cancer treatment needs to go, and he therefore made sure that thorough genomic testing was done on my tumour). And, the median time to seeing positive effects with Zeno is 1.9 months, so it shouldn’t take very many doses to show that it is working (or not). (That said, it is a median, so 50% of people who saw positive effects saw them before 2 months, and 50% after, but I have no idea how long after….). And, as I’ve said before, our hope is that if it is working, we can share the results with the drug company and the Ontario govt, and put pressure on them not to deny their life-saving treatment to a cancer patient. And, our other hope, probably the best of all possible worlds, is that the drug will shrink the tumour quickly so that I become eligible for surgery. I’ve been in touch with one woman in the USA who was on the drug for only 4 months, saw her tumours shrink by about 80 – 90%, and then had surgery. And this was after her first oncologist told her she had a year to live and there was very little they could do for her (she dumped him). Now she is NED. (No evidence of disease.) (She had to pay for a couple of doses herself before her oncologist managed to convince her insurance company to pay for it).

Anyway, I know some of you will want to help. We may set up a GoFundMe at some point. I will let you know if we go down that road. You may also want to write emails to the company, and I would ask that you not do that yet. (For one, it’s unclear which company to write to. Partner Therapeutics has the commercial rights in North America, but Merus is the actual drug developer, and Merus recently merged with Genmab). My husband and I are attending a conference next week about the approval process for new drugs for rare diseases in Canada. As part of that we will participate in a workshop titled “Navigating Drug Access and Negotiation in Canada” where one of the goals is learning “where and how patient input makes a difference.” In other words, I’d like to wait on putting pressure on the drug manufacturer until (1) I have a better understanding of how the approval process for new drugs works in Canada and what the CORD (Canadian Organization for Rare Diseases/Disorders) people consider best advocacy practices, and (2) we have evidence that the Zeno is working.

Finally I just want to say that I’ve been feeling great lately. At this time last year I felt like crap. I was exhausted and had very bad gastritis symptoms. I really only felt comfortable lying down. But now I feel like myself again. I don’t think this is an indication that the Zeno is working. It’s too soon for that. I think it’s that the chemo-immunotherapy worked to some extent, that I am now recovering from the toxicity of the chemo-immunotherapy, and that I am on the right kinds/doses of blood pressure and thyroid medication. I also know that with this disease how I feel doesn’t necessarily reflect what’s going on with the cancer inside me, and that how I feel could change pretty quickly. For all I know this time right now is the best I will feel for the rest of my life. So I plan to enjoy it!

More soon, probably after the two conferences I will be attending – the Rare Diseases conference in Toronto and the annual Cholangiocarcinoma conference in Salt Lake City.

    Just for the record, I’m super enthusiastic about ALL her posts. I think she’s exaggerating my reaction to the last one a little bit to create dramatic tension – a good narrative strategy! ;-)

    Ok, maybe “noticeably more quiet” would be more accurate than “less enthusiastic.” LOL

    I think the more telling detail might be that it costs $25,700 and fifty dollars per dose. Why not 38 dollars? or 99? You could even drop it back a digit or two. Why not $23,000? or $28.000?. Like car prices (Only $33,999!) these numbers are economic fictions. And even worse, some mortuarial (new made up word) actuary may have done a back of the napkin calculation on what a person might feasibly pay for an additional week of life. 😐

      Yes, you’re probably right about some actuary calculating how much someone might be willing to pay for extra life. My current frustration, however, is that new effective cancer drugs are approved by the FDA much more quickly than by Health Canada. Months and months more quickly. Another frustration is that drug manufacturers sometimes don’t even bother to apply for approval of a new drug in Canada because the consumer market for the drug will be so small.

        And Canada is not the only place where Zeno is not yet approved. I did a google search on “Is zenocutuzumab approved in the UK?” (Followed by in France, in Switzerland, in Belgium, etc.). It doesn’t seem to be approved anywhere except the US. It’s not even approved in the Netherlands despite the fact that the drug was developed by Merus, which is based in Utrecht! That said, it does look like it is under review by the European Medicines Agency, though unclear when approval might come through.

    It’s hard to even know what to say, how broken and complex and inhumane. I’m really glad to know the details and the costs.

      Thanks for commenting. It does feel like a broken system. But feeling its brokenness firsthand definitely motivates me to try to do something about it!

    We’re waiting for genetic testing to come back for my mom’s tumour and I’m really suspicious that it has the NRG1 fusion as her tumour has a signet ring pattern showing high mucin content. I was very excited about the possibility of her getting treatment, but I am thankful that you shared the cost. This will help me guide her to a treatment path that is realistic without wasting time hunting down something we ultimately can’t afford. There is so much labour in accessing information on cholangiocarcinoma and possible treatments. Thank you for sharing. Please keep us posted.

    Paper Moon, where are you located? If in the US, zenocutuzumab was just approved by the FDA for cholangiocarcinoma and was listed by the NCCN as recommended treatment for patients whose tumours have NRG1 fusion. That means it would be covered by health insurance. If in Canada, zenocutuzumab won’t be covered, but if your mom’s tumour has a different mutation – e.g. IDH1 – some targeted therapies, like ivosidenib, will be covered. I think some medicines for FGFR2 are also covered.

    And I totally agree re accessing information and staying on top of treatment possibilities. It can feel all-consuming, and maybe not a full time job, but definitely a part-time job. And I will definitely post updates. I’m getting a CT scan tomorrow (May 13). I’m hoping it will show the Zeno is having a significant impact, though it might be too early to tell (I will have only had 3 doses). Anyway, I’ll definitely post an update.

    Also, how do you know your mom’s tumour has high mucin content? Or a signet ring pattern? I have no idea what the content of my tumour is or if it is high or low mucin. Or even what that might mean.

    We’re in Toronto. I am so grateful that you shared what you are doing because it has saved me having to do all that figuring out by myself. I can understand your reluctance to share, but really want to emphasize that when you are writing to people who are invested all of the information is valuable. I hope your scans went well yesterday and I know it might be still too early but fingers crossed. Do you have to wait two weeks before you get the results?

    It’s completely possible that my mom turns out to not have the NRG1 fusion but this is why I feel suspicious. She has tested negative for all of the more common mutations so I was looking into what we do know specifically about her tumour. She’s WT1 positive, and on her biopsy report the write up noted that cell looked like signet ring pattern. (It was only mentioned when a new oncologist eight months in wanted to doublecheck that it wasn’t actually bowel cancer, which is where a signet ring pattern is most common.) The ring pattern occurs when there’s so much mucin in the cell that all of the components of the cell are pushed to the edge in a ring shape.

    I had been looking at the rarer possible mutations so the word mucin made me take a look again at the NRG1. That fusion mutation is mostly in lung cancer, particularly IMA lung cancer, and the M in IMA stands for mucinous. NRG1 has the HER2/HER3 always stuck in the on position, and one of the downstream pathways of that is excessive mucin production. 

    IMA are not KRAS wild type, and their mucin production is outside of the cell as well as inside.  IMA do not have a ring pattern to their cell, and honestly I couldn’t find anything that said NRG1 fusions were associated with signet ring patterns, but mucin production is a spectrum. You can have a little extra mucin, or you can have a lot of extra mucin. The signet ring pattern is the result the far edge of that spectrum. There are other mucinous cholangiocarcinomas but they are normally large duct, and my mom’s tumour being WT1, means it is likely small duct. 

    I figured my mom‘s tumour has no other known, genetic mutations, but something Is happening that affects the production of mucin in a really abnormal way, and when I looked around at the possible mutations and how they work, the NRG1 fusion still seemed like the most likely culprit. There were other incidental things that didn’t contraindicate that it could be. The mutation occurs most commonly in colangiocarcinoma that are KRAS wild type with no other mutations present like my mom’s. Her cancer being WT1 Indicates that it is from the small ducts, which the NRG1 Is also associated with. 

    We should get her results from the Caris M1 profile testing back in a week. ($4,500 US) I know we might still not have any answers after but I feel like the possibility would still be worth pursuing. Now that I know how expensive Zenocutuzumab is I’ll ask her oncologist about Afatinib. I’m super thankful to be able to confidently drop it, and not build my mom‘s hopes up about it unnecessarily. Please keep us posted about your journey. My mom and I will be wishing you good results on your CT even if it is still too early.

    Paper Moon, wow, that is very complex. You sound like you know a lot about tumour cell biology. I hope it turns out that your mom’s tumour has an actionable mutation. Let me know if turns out she has the NRG1 mutation.

    My CT scan yesterday was chest/abdomen/pelvis. They always report the chest separately and first, and that report is already in. No spread, no change. So that’s good news. I probably won’t hear about abdomen/pelvis for a week or so. Though maybe they will do a rush job because they know that it could affect whether we keep paying for the Zeno or not.

    Is your mom being treated at PMH?

      No she’s at Sunnybrook. Ha, yes a super long answer. it was an effort to send it down to The States for complete RNA sequencing, so it was satisfying to explain what we were thinking about. I know it is a longshot, but possible still. Speaking about details, did you get tested through PMH? You’re right they could fasttrack the radiologist report since it might impact your immediate decisions.
