Black Pepper and Tisotumab Vedotin-Tftv

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Tisotumab Vedotin-Tftv

Tisotumab Vedotin-Tftv falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Black Pepper interacts with.

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.
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 short version for Tivdak (tisotumab vedotin). Black pepper extract, called piperine, may slow down a liver enzyme called CYP3A4. The small molecule released from this antibody-drug conjugate (a chemo payload called MMAE) is partly cleared by that same enzyme. So in theory, concentrated piperine could let a bit more of that payload linger in your body, which might add to side effects like eye irritation or dryness, nerve tingling, nausea, fatigue, or bleeding.

I want to be honest about how soft this evidence is. This comes only from lab and computer-model studies, not real patients, and the everyday black pepper you sprinkle on food is very unlikely to matter. The bigger question is supplement-strength piperine. Since Tivdak is serious cancer therapy, please run any pepper or turmeric supplement past your oncology team first.

  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

About Black Pepper

What is Black Pepper?

Black Pepper
  • Flavoring and culinary use
  • Digestive complaints like bloating and indigestion
  • Boosting absorption of other supplements
  • Antioxidant and anti-inflammatory support
  • Cold and congestion remedies

Black pepper is a common kitchen spice that is generally safe in the amounts used in food. Its extract, piperine, is mostly added to supplements to help the body absorb other ingredients (like curcumin from turmeric). Strong human evidence for black pepper treating specific health conditions is limited, so use supplement-strength products with care and check with your pharmacist.
