Scoop

I had a chance to speak to Alice today about my reaction on Tuesday and one of my questions was how common IR’s or infusions reactions, are. Not rare, but in the single digits as far as percentage.

So far I’m not doing a very good job of being unremarkable.

The good news is that we have the go ahead to try again. Plan of action is to stick with the pre-dosing of Allegra and steroids, but to also dose again just as we are beginning infusion. And to infuse at 1/2 the rate with Bendadryl administered intravenously simultaneously.

I’m going to be coming and going and am definitely not looking forward to a repeat of the Benadryl crawlies. My friend Gina sent me a weighted blanket and I will bring that with me on the day of infusion to see if it makes a positive difference.

In the meantime I’m feeling OK. Profoundly tired yesterday but I have to wonder if some of that was just coming off all the steroids. My fatigue is more low key today.

Onward. I hope this shit works. Particularly as this is mutation agnostic, and therefore potentially a viable treatment option for a large number of people.

I shall keep you posted πŸ™‚

Infusion confusion

So oh boy. Infusion began around 12:40 pm with little drama. However, just about an hour in, my throat began to suddenly hurt. I was looking for the call button but my nurse was peeping through the glass doors. When she came in I explained that not only was my throat painful, it felt as if it was swelling shut.

Gatekeeper to my veins

She immediately turned off the infusion and then things got a little bit more exciting. My neck and back developed a rash and hives and the strange feeling in my throat moved to my palate. It was getting harder to breathe and an oxygen mask was put on and I was given intravenous benadryl as well as more steroids. Lots of people in the room assessing the situation as this was a classic infusion reaction/hypersensitivity–despite pre-dosing with antihistamine and steroids.

Damn. I was hoping I could will myself to not react. But no. Saline was administered next and a repeat of steroids as my throat wasn’t feeling any better and I was starting to cough as well. And then restless leg syndrome kicked in crazy bad as a result of the Benadryl.

An hour passed before the symptoms of hypersensitivity subsided (but not the restless legs) and we gave it another go at a titrated speed. Forty five minutes later, my throat was suddenly very painful and swallowing difficult. The back of my neck started to itch and rash out as well and so the infusion was stopped. I was given more steroids and an executive decision was made not to finish dosing.

We clearly have a complication going forward. I really don’t want to drop down on dose if I don’t have to. Dr. Lin is going to have a discussion with the trial team and sponsor to see if they can come up with some strategies to get me through an infusion.

So here I am four more EKGs (I was mistaken as to how many were required today) and a whole lot of blood draws later. One more EKG at 7:30 and two more vials of blood and then I am released. Long, long, slightly disappointing day.

Hopefully my cancer is currently as uncomfortable as I am.

And so it begins

Milk thistle and dandelion tea plus a hella lot of water and I got those enzymes down more than forty points. So my biopsy was a go yesterday.

Happy to report that it all went smoothly and to my delight (the perks of a progressing cancer) the surgeon was able to go in from the side of my chest rather than straight through my left boob (no fun). This meant that A. I could watch the biopsy on a screen–not everyone’s cup of tea but I thought it was wicked cool–and B. my time in recovery was spent on my side rather than flat on my stomach; so much more comfortable.

It was a long, long day and big credit to my friend Diane who ferried me to and from. I am so very grateful for my incredible cadre of friends.

This morning a friend of Diane’s kindly picked me up at 5:30 am for the first day of the DS-1062a trial (‘DS1062aΒ is a trophoblast cell-surface antigen 2 (TROP2)-targeting antibody drug conjugate’).

Room without a view

I have now been at the Termeer Center for Targeted Therapies for almost five hours. In that time I have been weighed, had two vials of blood drawn, and the first of three EKG’s taken. I have also peed twice, napped, and met with Dr. Lin, my new oncologist now that I am on trial. Drug was finally released an hour ago but it is frozen and takes three hours to defrost, so infusion will not begin until one. Lots of hurry up and wait.

Last night I was pre-dosed with five 4 mg tabs of dexamethasone as well 360 mg of fexofenadine, both of which will be repeated just prior to infusion. There have been lots of reactions to this experimental therapeutic but fortunately I am entering trial after MTD has been established and they are getting a better handle on how to handle side effects. Also anticipated are some pretty gnarly sounding mouth sores (dime size, painful plaques) which could put a crimp in my dating schedule πŸ˜‰ I am to prophylactically swish with a steroid mouthwash and have a paste for when they emerge. I have been advised that I shall likely lose weight (those sores) and may lose my hair as well. And there have been some eye issues, so I have been using lubricating drops. Aside from that, fatigue and mild nausea. There is always a price to pay.

On a positive note, some of the side effects of lorlatinib have noticeably receded. My skin—a mess of crusty sores as of late, has begun to clear up and heal (hallelujah). I had to go off of statins because of my elevated liver enzymes and my cholesterol was through the roof last time (high 300’s) but hopefully that shall start to come down as well. The cadence of my speech is speeding up (‘So you’re not going to sound like John Wayne anymore?’ asked one of my friends) and I am already feeling more like me: Linnea pre lorlatinib. Less rage-y, more clearheaded. I like it.

So consider this installment one. More to come post infusion.

It was

Me giving me encouragement: the Wall of Hope on floor eight of the Yawkey building at MGH. When I first started getting treatment, a secret goal was to one day appear on the Wall of Hope. πŸ™‚

A long, long day. But in the parlance of my kind (the terminally ill), a long day beats a short day all to heck.

First, my life is blessed with a plethora of goddesses. Childhood friends, my daughter, sisters, my many new friends, nurses, phlebotomists, counselors, medical doctors. Men are great and I love a heap of them as well but this group of women has been my consistent go to for the tough stuff.

One goddess was in tow yesterday, my friend Sally: pals since the fifth grade. I am beginning to realize how beneficial it is to have company at these visits, after years and years of going it alone.

I had an appointment with the goddess who takes care of me from the neck up (as I like to say), Mary Susan Convery, my thoracic social worker. She keeps my head on straight.

A quick trip down Charles St for a hug from my daughter (Sally is her actual godmother) and a delicious lamb sandwich at Tatte. And then a long wait in those spaces appropriately called waiting rooms.

Oh, the irony. Those of us to whom time is so precious spend far too much of it waiting.

Anyway, the action got started around four with a visit from the head goddess, Alice. Chit chat about how I am feeling (great for the moment, on that artificial steroid high, my dyspnea temporarily under control.) But I was eager to cut to the chase—how about those scans? She had read them herself and her assessment was that they were mildly worse than the ones in December. Now remember this is while getting chemo so bummer. Of concern is the lymphangitic spread as well as the fact that the slight amount of fluid in the bottom of my left upper lobe is also increasing.

Alice puts more store in symptoms though and mine are not encouraging. Definite downward trend. So we agreed that I’d go ahead and get chemo one more time (and possibly two, depending on timing and tolerance) in the hope that it is at least slowing down progression.

There was a bright spot though and that was in the form of options. I figured we were down to one–lorlatinib plus a mek inhibitor. But Alice described yet another possibility. That after all these years on TKI-s it might be good to take a break. Maybe let my cancer forget some of what it has learned. To try a novel therapeutic, one my cancer is completely naive to.

While getting infused I signed the consent forms for a phase I clinical trial for a drug called DS-1062a; an antibody drug conjugate which targets a protein called trophoblast cell-surface antigen2 (TROP2), which is found in copious quantities on the surface of cancer cells.

This sounds exciting to me–a fresh possibility. But it is going to be intense. First there are the necessary hoops to jump through in order to qualify, including a lung biopsy, heart scan, ECHO, and eye exam. And all that blood, blood, blood (30 teaspoons for the first three cycles).

Every three week infusions but the first week, at least two additional visits. And then for the subsequent nine weeks, I return to the hospital once a week, with a second lung biopsy at week two. It is going to be consuming–that is, assuming I qualify.

But it also has given me fresh hope (I love the luxury of choices).

Good thing. Chemo may not be kicking cancer’s ass, but it is kicking mine. My liver is a tad inflamed–Alice asked me if alcohol might be involved. Truth? Yes. Goodbye to that for the time being. Sally filled me with healthy fluids last night and this morning she made me oatmeal, hot lemon water, and a vegetable chicken soup. I am in good and loving hands.

So yes. Stability or response would have been the preferred report but this feels if not a door, at least a window. And that’s what I need. Fresh air and a bit of a vista to contemplate.
