Cycle 1 Dose 4 Day 3 of My Clinical Trial of Epcoritamab for CLL: Getting Better All the Time

In science and medicine, information is constantly changing and may become out-of-date as new data emerge. All articles and interviews are informational only, should never be considered medical advice, and should never be acted on without review with your health care team.

I have got to admit it’s getting better.”  Lennon/McCartney

My dose of 100 mg of prednisone, a potent steroid, will calm a world of inflammation. And I was undoubtedly inflamed, but not for long, and I feel much better now. The odds are in my favor that the worst is behind me. The cytokine release syndrome, or CRS or less politely called cytokine storm, that had me shaking two nights ago with fever and a racing heart was technically only Stage 1 CRS, as mild as it gets. There was no drop in blood pressure or need for supplementation or other support to move it to a higher stage. Stage 1 or 2 CRS is typical for bispecific antibodies such as epcoritamab, where CRS tends to be milder than that seen with CAR-T. 

The steroid to prevent and calm CRS still makes sleep a challenge, but with no hiccups and no pain to keep me awake, when I did sleep, it was sound.

While my need to be inpatient for future dosing is over, the protocol seems to demand a 5th week of steroids taken outpatient for the 2nd full dose of 48 mg. to knock back my chronic lymphocytic leukemia (CLL). Around 16% of lymphoma patients can get CRS recurrently, and it’s usually after this next dose, but I am betting I won’t be that unlucky 1 in 7. ICANS or neurotoxicity also can occur later, but it is even rarer. I will be alert and prepared for both, but I think I have endured the worst of any chomping that this BITE (bispecific T-cell Engager) is aiming at me.

I have been forcing myself to walk daily even when I am in no mood. Also, doing weight training, but not enough high-intensity interval training. It’s important and boosts immunity.

Saving the best news for last: It looks like it might already be working. Dr. Danilov isn’t committing, but he thinks one of my only two palpably enlarged nodes, the one in my right axilla (armpit), is softer and smaller. I agree. YAHOO! It’s working its magic within a day after a single therapeutic dose. My lymphocyte count has fallen, too, but the high prednisone dose can cause a transient dip of no clinical significance. So, I’ll need to see if it continues to trend down before celebrating that as a definite win. Yet there is still good reason to believe that my CLL is being nibbled away by my immune system with a helpful push from an engineered monoclonal antibody. My restaging MRI in October will reveal a more detailed story after five full doses. That result will be significant.

This is all I could ask for at this point. The nasty but tolerable 100% anticipated CRS is probably in the rearview mirror and hints at some early efficacy.

There are more trial labs tomorrow, but nothing I’ll see to report. My poor veins are taking a beating. The next subcutaneous injection is on Tuesday, so there will be fewer blog posts in the future. And that is a good thing.

Stay strong. We are all in this together.

  1. I’ve been waiting to comment until it appeared you might be ‘over the hump’, and this latest post makes me believe, my friend, that this day has happened. I wish you continued progress with no more hiccups(pun intended)

  2. Dear Dr. Koffman,
    Great to hear that you’re doing so well! Thanks very much for spreading your news. As usual, you are a trail blazer for the rest of us.

  3. Good news Brian.

  5. Great to see this post Brian and that things are getting better on all accounts, including those hiccups. Thank you for explaining each step of the way as you help us all by participating in this trial.
    I was surprised to read that you are still weight training through this all? Do you pack your weights for your inpatient stays? and do hiccups count as resistance training (sorry, couldn’t resist)?

  6. LET’S GO!!
    I am loving the progress Brian and eagerly await the next update!
    You will be in all of our thoughts during the Tuesday OC meeting and you will be missed 🙂

  9. Brian,

    I look forward to having a robust, free-wheeling conversation with you in the near future. Your sharing of this journey is richly informative, and greatly appreciated. It keeps us connected, rather than wondering. Thank you for your generous spirit.
