Why this applies to Belinostat

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
Green tea extract supplements have been linked to several cases of hepatotoxicity and might have additive hepatotoxic effects with other drugs..
Severity Moderate Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with belinostat (Beleodaq) and green tea. This isn't about green tea changing how your body breaks belinostat down. Instead, the concern is that both can be hard on the liver, so using them together might add up and stress your liver a little more. Belinostat can already cause liver enzyme changes during treatment, which your cancer team watches closely with blood work.

To be honest, this is a theoretical worry based mainly on rare anecdotal reports, and it's considered unlikely. The bigger flag is concentrated green tea extract pills, not a normal cup of green tea, which is usually fine. Since you're on a serious therapy, please run any green tea supplement past your oncologist or pharmacist first.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Belinostat also falls under P-GLYCOPROTEIN SUBSTRATES.

Green tea might increase the levels and adverse effects of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that green tea inhibits drug efflux by P-gp, potentially increasing serum levels of P-gp substrates. Case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking green tea and certain P-gp substrates.
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

Belinostat (Beleodaq) is a chemo drug given by IV for a type of lymphoma, and your body uses a tiny cellular pump called P-glycoprotein to help move it around and clear it. Green tea may slow that pump down a bit. In theory, that could let a little more belinostat hang around in your system, which might mean more of its usual side effects like nausea, tiredness, low blood counts, or stomach upset.

Here's the honest part: this concern comes from lab studies and scattered case reports, not strong proof, and it's more likely with concentrated green tea extract pills than a regular cup of tea. Since belinostat is a serious cancer treatment, please tell your oncology team and pharmacist before adding any green tea supplement so they can guide you.

About Green Tea

What is Green Tea?

Green Tea
  • Antioxidant support
  • Weight loss
  • Heart health
  • Mental alertness
  • Cancer risk reduction

Green tea is a popular beverage rich in antioxidants called catechins, and drinking it in normal amounts is considered safe for most people. Concentrated green tea extracts are a different story—they may help modestly with weight or heart health for some, but high doses have been linked to rare liver problems. Talk to your pharmacist or doctor before taking green tea supplements, especially if you have liver concerns or are pregnant.

About Belinostat Injection

What Is Belinostat Injection Used For?

Brand name: Beleodaq

Beleodaq (belinostat) injection is approved to treat adult patients with relapsed or refractory peripheral T-cell lymphoma (PTCL) — a fast-growing type of lymphoma (blood cancer) that either came back after treatment or never fully responded to it.

This approval is based on how well the cancer responded to the drug, including how long those responses lasted. Whether Beleodaq extends overall survival or improves disease-related symptoms has not yet been established. Continued approval may depend on results from a confirmatory trial.
