European Mistletoe and Sutimlimab-jome

Here is the interaction we found between these two, with the evidence behind it.

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Sutimlimab-jome

Sutimlimab-jome falls under IMMUNOSUPPRESSANTS — the group European Mistletoe interacts with.

Theoretically, European mistletoe might decrease the effectiveness of immunosuppressants.
Clinical and in vitro studies suggest that European mistletoe might have immunostimulant effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the idea behind this pairing. Sutimlimab (Enjaymo) is a lab-made antibody that calms one part of your immune system, the classical complement pathway, to protect red blood cells in cold agglutinin disease. European mistletoe, on the other hand, seems to do the opposite in lab and animal studies: it appears to rev up the immune system. So in theory, mistletoe could work against what sutimlimab is trying to do and make it less effective, meaning your red blood cell counts could slip, leaving you more tired, short of breath, or pale.

I want to be honest though, this is a theoretical concern based only on test-tube and animal data, not real cases with this drug. Still, mistletoe can be toxic and should only be used under medical care. Please check with your oncologist or pharmacist before combining them.

About European Mistletoe

What is European Mistletoe?

European Mistletoe
  • Cancer supportive care
  • Immune support
  • High blood pressure
  • Anxiety and stress
  • Inflammation

European mistletoe is a parasitic plant most studied as an injectable extract used alongside conventional cancer care in some European countries, mainly to improve quality of life rather than to cure cancer. The plant is toxic if eaten, and oral or self-treatment can be dangerous, so it should only be used under medical supervision. Talk to your pharmacist or doctor before using any mistletoe product.

About Sutimlimab-jome Injection

What Is Sutimlimab-jome Injection Used For?

Brand name: Enjaymo

Enjaymo (sutimlimab-jome) injection is indicated for the treatment of hemolysis — the breakdown of red blood cells — in adults with cold agglutinin disease (CAD). CAD is a rare autoimmune condition in which the immune system mistakenly attacks and destroys red blood cells, especially in cold temperatures.

Enjaymo works to stop this destruction by targeting a key part of the immune system called the classical complement pathway. It is approved for adults only; safety and effectiveness in children have not been established.
