The Pharmacist’s Take By · Clinical pharmacist · Written

Zaltrap (ziv-aflibercept) is an IV cancer medicine added to FOLFIRI chemotherapy for metastatic colorectal cancer (cancer that has spread) that has kept growing despite an oxaliplatin-containing regimen. It works like a sponge, soaking up the growth signals tumors use to build new blood vessels, and has been a specialist second-line option since about 2012, available only as the brand. The combination is tough, and diarrhea, mouth sores, tiredness, nosebleeds and rising blood pressure are what most people notice, which is why blood pressure is checked every two weeks. Bleeding and holes in the bowel are the risks to take most seriously, so black or bloody stools, coughing up blood or severe belly pain mean calling your care team right away.

Clinical pearls

  • Zaltrap must be stopped at least 4 weeks before elective surgery, so tell any surgeon early, since it also slows wound healing.
  • Diarrhea can become severe, especially in people 65 and older, so get an anti-diarrhea plan from your oncology team before starting.
  • Foamy urine or new swelling can signal protein loss through the kidneys, which is why your urine is checked regularly.
  • Use effective contraception during treatment and for 3 months after, and avoid breastfeeding until 1 month after the last dose.

Patient information guide A plain-language walkthrough of Ziv-aflibercept Injection, written from its FDA label.

What Ziv-aflibercept Injection is used for

▾

Ziv-aflibercept Injection is used for one cancer indication.

  • Zaltrap, given with FOLFIRI, treats metastatic colorectal cancer that is resistant to or has progressed after an oxaliplatin-containing regimen.

How Ziv-aflibercept Injection works

▾

Zaltrap is a soluble receptor that binds VEGF-A, VEGF-B and PlGF. These are signals that help new blood vessels grow and make vessels leaky. By blocking them, Zaltrap can reduce new blood vessel growth.

In animals, it slowed endothelial cell growth and the growth of colon tumors.

Ziv-aflibercept Injection dosage

▾

Zaltrap is given by IV infusion in a clinic over about 1 hour, every 2 weeks, along with FOLFIRI. It is given first on treatment days. It is never given as an IV push.

  • Your dose is based on your body weight.
  • Your team may pause or lower the dose for high blood pressure or protein in the urine.
  • Food does not apply, since it is given by IV.
  • If you miss an appointment, contact your care team to reschedule.

Dosing details from the FDA-approved label

From the Ziv-aflibercept Injection prescribing information (“Dosage and Administration”). Doses are set by your prescriber for your product, condition, kidney function and age — never change a dose on your own.

  • Recommended dose and schedule (in combination with FOLFIRI)
    • 4 mg per kg of actual body weight as an intravenous infusion over 1 hour every two weeks in combination with FOLFIRI until disease progression or unacceptable toxicity
    • Administer ZALTRAP prior to any component of the FOLFIRI regimen on the day of treatment
    • Do not administer as an intravenous push or bolus
  • Uncontrolled hypertension
    • Temporarily suspend ZALTRAP until controlled
    • Upon resumption, permanently reduce the dose to 2 mg per kg
  • Proteinuria of 2 grams per 24 hours or more
    • Suspend ZALTRAP and resume when proteinuria is less than 2 grams per 24 hours
  • Recurrent proteinuria
    • Suspend ZALTRAP until proteinuria is less than 2 grams per 24 hours and then permanently reduce the dose to 2 mg per kg

Before taking Ziv-aflibercept Injection

▾

  • Heart failure: no trial experience in NYHA class III or IV.
  • Severe liver impairment: not studied.

What Ziv-aflibercept Injection does in the body

▾

Zaltrap blocks VEGF-A, VEGF-B and PlGF, which reduces new blood vessel growth and vessel leakiness. In a study of 87 patients with solid tumors, no large changes in the heart's QT interval were seen. A small increase of less than 10 ms could not be ruled out.

How your body processes Ziv-aflibercept Injection

▾

Steady-state levels of free ziv-aflibercept were reached by the second dose. The half-life is about 6 days (range 4 to 7 days) with dosing every two weeks. Age, race and sex did not have a clinically important effect on exposure. People weighing 100 kg or more had about 29% higher exposure.

Mild and moderate liver impairment did not affect clearance. There are no data for severe liver impairment.

How to store Ziv-aflibercept Injection

▾

Store ZALTRAP vials in a refrigerator at 2°C to 8°C (36°F to 46°F). protect from light.

Ziv-aflibercept Injection: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Ziv-aflibercept Injection — the kind of thing our pharmacy team would talk through with you at the counter.

What is Zaltrap used for?

▾
Zaltrap is given with FOLFIRI chemotherapy to treat metastatic colorectal cancer. It is for cancer that has resisted or progressed after an oxaliplatin-containing treatment.

How will I get it?

▾
It is given as an IV infusion over about 1 hour, usually every 2 weeks, before the FOLFIRI drugs. It is never given as a quick push. Your care team will follow the label for your dose.

What side effects should I expect?

▾
Common ones include diarrhea, mouth sores, tiredness, low blood counts, high blood pressure, protein in the urine, nosebleeds, headache and decreased appetite. Tell your team about any that bother you.

When should I call my care team right away?

▾
Call for serious bleeding, severe belly pain, chest pain, stroke-like symptoms, very high blood pressure, a severe headache with confusion, fever or infection signs, or severe diarrhea. Also report wounds that won't heal.

Do I need to worry about surgery?

▾
Yes. Zaltrap must be held at least 4 weeks before elective surgery. It is not restarted after major surgery until the wound has healed.

Is it safe in pregnancy?

▾
No. It can harm an unborn baby. Use effective contraception during treatment and for 3 months after your last dose, and don't breastfeed during treatment or for 1 month after.

Is Ziv-aflibercept Injection available over the counter?

▾
No. Ziv-aflibercept Injection is a prescription medicine: every Ziv-aflibercept Injection product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Ziv-aflibercept Injection first available?

▾
The earliest FDA record we hold for Ziv-aflibercept Injection is from 2012: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Ziv-aflibercept Injection was first used.
