Cannabidiol (cbd) and Asciminib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

Why this applies to Asciminib

Asciminib falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Cannabidiol (cbd) interacts with.

Theoretically, CYP3A4 inhibitors might increase cannabidiol levels.
Cannabidiol is a substrate of CYP3A4 enzymes. Theoretically, drugs that inhibit CYP3A4 enzymes might increase levels of cannabidiol, increasing its effects and adverse 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 key thing about this pairing: it's the CBD level that may climb, not your asciminib. Asciminib (Scemblix) can mildly slow down an enzyme called CYP3A4, and CBD happens to be broken down by that same enzyme. So in theory, taking them together could let CBD build up a bit, which might make CBD side effects more noticeable, things like drowsiness, an upset stomach, diarrhea, or changes in liver-related lab numbers.

I'll be honest with you, this one is theoretical, based on how these compounds behave on paper rather than real patient reports, so it may not amount to much. Still, since asciminib is treating something serious and CBD products vary a lot in quality, please loop in your oncology team or pharmacist before combining them.

From our pharmacist’s overview on the Asciminib page

“Asciminib (Scemblix) treats chronic myeloid leukemia, and a steady blood level is what keeps the cancer suppressed, so this list deserves real care rather than a quick skim. Seventeen of the 31 supplements on file are fibers, gums, and charcoals that can block or slow how much of each pill your gut actually absorbs.”

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

  • Anxiety and stress
  • Sleep problems
  • Chronic pain
  • Certain seizure disorders
  • Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.

About Asciminib

What Is Asciminib Used For?

Brand name: Scemblix

Scemblix (asciminib) is used to treat adult patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase (Ph+ CML-CP) — a type of blood cancer driven by an abnormal protein called BCR-ABL1. It covers three groups: people newly diagnosed with Ph+ CML-CP, people who have already been treated for Ph+ CML-CP, and people whose cancer carries a specific mutation called T315I that makes it harder to treat.

The use in newly diagnosed Ph+ CML-CP was approved under accelerated approval based on early response data. Continued approval for that specific use may depend on results from confirmatory trials confirming long-term clinical benefit.
