Beet and Mobocertinib Succinate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Mobocertinib Succinate

Mobocertinib Succinate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Beet interacts with.

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.
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 gist for Exkivity (mobocertinib): your body relies on a liver enzyme called CYP3A4 to break this medicine down and clear it out. Lab research hints that a pigment in beets, called betanin, might slow that same enzyme. In theory, that could let mobocertinib build up a bit higher than expected, which may mean more side effects like diarrhea, nausea, mouth sores, or heart rhythm changes (QT prolongation).

Now, the honest part: this is based only on test-tube data, not on real people, so we don't truly know if eating beets matters here. A serving of beets at dinner is very different from concentrated beet supplements. Because mobocertinib is a serious cancer drug, please run any beet supplement by your oncology team before using it.

From our pharmacist’s overview on the Mobocertinib Succinate page

“Mobocertinib (Exkivity) is a targeted therapy for a hard-to-treat lung cancer, which makes dosing precision matter and this list worth real caution. Most of the 146 supplements on file can shift the drug's blood level, because mobocertinib is cleared by CYP3A4, an enzyme many botanicals speed up or slow down.”

About Beet

What is Beet?

Beet
  • High blood pressure
  • Exercise and athletic performance
  • Heart and circulation support
  • General antioxidant/anti-inflammatory support
  • Liver and digestive support

Beet, especially beetroot juice, is a nitrate-rich food that may modestly lower blood pressure and slightly improve exercise performance in some people. It is generally safe as a food, but supplement effects are modest and not a substitute for prescribed treatment, so talk with your pharmacist or doctor before relying on it.

About Mobocertinib

What Is Mobocertinib Used For?

Brand name: Exkivity

  • Mobocertinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that cannot be removed by surgery and has spread to other parts of the body either during or after treatment with platinum chemotherapy medications. Mobocertinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells and may help shrink tumors.
