My Brentuximab Fling

Clinicians and patients differ in their opinions about Prednisone. Clinicians seem to view the drug as a last resort, a temporary fix to be used sparingly for a short duration. As short as possible. We patients, however, love the stuff. It makes us feel wonderful. We can frolic in the sunshine, climb hills – slowly, but we make it – talk incessantly and feed constantly. In short, we feel well and like to stay on the steroid for as long as we can.  Oh there are some negatives; degrading quad muscles, degrading biceps, minor sleep impairment, facial puffiness, and some funky liver enzyme readings, but did I mention I sunshine frolicking? I was allowed Prednisone over the Christmas period. It was wonderful. It even offers me temporary reprieve from my rigors. Simply wonderful.

My ICE relapse complicated further treatment plans. Actually, it put a complete halt to them. Other options were required. The easiest was to use a different strain of chemo, but I am kind of running out of those. I have been exposed to most chemo classes, therefore the chance that a different agent will actually help me is limited. The resistant cells will merely grow stronger. I think there is one chemotherapy class that I have not yet tried. Another option was a targeted chemotherapy drug called Brentuximab. Hodgkin’s cells express a cell marker called CD30. It sticks out on the cell like a little flag declaring its individuality from those surrounding it. Brentuximab contains an antibody complex that targets CD30. The drug floats around the body searching for any CD30 flags. When it finds one, the antibody attaches to the cell and pumps it full of a chemotherapy agent. It is a lock and key approach. Imagine you are standing in a hotel corridor with a key but no room number. The only way to find out which room you are in is to try all the locks. Oh look, the key fits in this lock, this must be your room. But wait, someone else is already in the room. Well you’d better punch them in the face, Bruce Lee style. That is pretty much how Brentuximab works.

This drug had been around for a few years now, but it is usually only used for patients who relapse after their autologous stem cell transplant. There have been a couple of trials using it on patients pre-transplant, but they are not sufficient for the New Zealand drug agency, Pharmac, to automatically fund Brentuximab. Strangely enough, the New York blogger I mentioned, probably a year ago, was a participant one of those trials. It is a small Hodgkin’s world. Brentuximab was the drug my consultant wanted to use so he asked Pharmac to fund it for me. This required a bit of research on his behalf, a named application followed by a cost benefit analysis. I don’t know if they attached a personal reference and a photo as well; it did sound complicated. For my non-New Zealand readers Pharmac is deemed a bit of baddie. They only make negative headlines over here. Nobody wishes to be denied treatment for financial reasons, and media outlets, well, they eat those stories up. In a Christmas pantomime, Pharmac would be booed on entry.

The application was two weeks into another limbo period. One would think that with all my prior practice in waiting, my patience would now be pretty good. It is not. Well it is to a certain extent. Tell me there will be no news for a week and I will be fine for that week. But once those seven days elapse I start to become restless, distracted, cantankerous. Initially the wait for Pharmac was to be three days, then seven, then ten. I did not expect the funding to come through. I expected them to reply “Try more chemo. If that fails get back to us.” In an odd ironic twist, if they didn’t respond before a certain date, I was going to require the chemo anyway. One can’t help but smile at that. But Pharmac responded in time. They responded with a yes, which leaves me a little confused – do pantomime villains actually have layers? Our families were ecstatic with the news, but I must confess I felt indifferent.

The ten day wait for Pharmac was nothing compared to the wait for the actual drug. There are no stocks in New Zealand. An Australian company said they could deliver it to us in a week, with it arriving Christmas Eve. I was to attend the day ward the Tuesday after Christmas ready for my Brentuximab. But it hadn’t arrived. It was “in transit”. Transit from where, no one knew. They weren’t even sure if it was in transit to Wellington, or to the Australian company. Just that it was in transit. For the next two weeks we spent our days waiting for a phone call announcing its arrival. Eventually we got a call “Ah it has left Australia”. What? It was only now in Australia? A call a few days later “It is in Auckland. We will try to get an overnight courier, so come in tomorrow afternoon.” It turns out it was held up in customs in Auckland as it cost (far) more than the GST import threshold, and customs would like some tax please. I am not sure how that was resolved, but I know it infuriated my clinical team. It took three weeks for the Brentuximab to get to Wellington. Some say it was sent by kayak.

During this waiting period Mike and I binged on the second season of Fargo. It was a bit fucked up. Not the scene where they bury a guy alive in molten asphalt, I can handle that, but the thirty year old wife who has lymphoma and is on experimental drugs. And we know she dies. We know because Molly’s mother was dead in the first season, and she died of cancer. Ah but we’ll just let the senseless killing around her, around us, distract us from battles that need to be fought, fought without killing anyone. That and Kirsten Dunst’s performance. Which was awesome. 

Anyway, after my Penelope inspired patience (and weeping), and some excitable distractions courtesy of a surprise visit by my Scottish sister, I was ready for this Brentuximab shit. I was all psyched up, prepared for all the worst side effects, and it was totally anti-climactic. A little fuss and excitement was had in the day ward, but physically nothing. Nausea: nil. Cell counts: completely normal. Hair loss? Nope, more like super hair growth, which is good because I was looking like a humanoid cylon prototype, with tubes under my skin and a shiny skull. So there were no side effects. Maybe I could imagine some fatigue. But that could also be the steroid withdrawal. And the infusion only lasted thirty minutes. I had it in the day ward. No overnight stays.

Three weeks of Brentuximab, a week off, then three further weeks. That was the plan. After the first three weeks I was finally fever free. My heart rate was a charming 79 and I was starting to feel much better. Granted I still had prominent lymph nodes in my neck and groin, I was still experiencing night sweats, and my spleen was causing me grief, but overall I felt nearly well. My consultant allowed us an anniversary trip, which we’d kind of already partially booked. The trip took us to the northern Coromandel, completely off the grid. The plans were for walking, swimming (paddling for Liv), nature and books. Maybe even some beer. And no contact with the outer world. We were to forget our current worries.

My rigors started on the second day. The lymph nodes burst through later that evening.  You can ignore, or at least weakly justify, the changes for a couple of days, but once the rigors become regular and the fevers creep higher, well we knew, we both knew, what was going on. It was fortunate that we were completely alone, in our hired bach, sitting on the deck listening to the kiwi and the morepork chat to each other – the morepork always has the final say – as it gave us a peaceful setting to contemplate my fairly obvious relapse. I set myself to weeping. I was glad that we were off the grid. It is difficult to correspond with people when everything is getting worse and our future is becoming uncertain and bleak. Since November we have had three weeks, those first three weeks of Brentuximab, where we have definitively known what was going on. So if you’re wondering how I am, be rest assured that I am shit. Except, of course, for that one Thursday when I saw my consultant and I was well. There is not much point in asking how I am. It is strenuous and exhausting responding to multiple messages.
Ok, so it wasn't all doom and gloom
The day before we left my temperature shot up to 40°C. We made an obligatory call, which went unanswered, to my clinical nurse who is holidaying in the North of England. I hear it is charming there at this time of year. Really the phone call was so we could claim that we hadn’t broken all the rules. Only the remoteness, the untreated drinking water, the unpasteurised cheese… They were not overly impressed at the day ward when I admitted the 40°C fevers.

I have started Prednisone again. I pretty much begged them for it. It doesn’t seem as effective this time. There has been no frolicking, and although the rigors have gone, the fevers still remain. In my gut I had believed Brentuximab would work. But it didn't. It is another limbo period treatment wise. We don’t know what the next step is. No one does. Emails are being fired between here and Australia, opinions are being sought, but a decision is yet to be made. I now know that these limbo periods need to be covered by steroids because Liv’s body and mind and husband cannot deal with long frequent rigors. They are debilitating. And, during this current period of high grade fevers, Wellington decides to throw out a fortnight of scorching weather. But at least now I am now grateful for the wind.
