If you are eligible for the Blenrep patient assistance program you can receive your medication for free.

Am I eligible for the Blenrep patient assistance program?

You could receive your Blenrep without paying the full retail price if you meet the eligibility criteria for assistance. The eligibility requirements are set by the pharmaceutical companies that are providing assistance programs. At NiceRx, we review each application individually, although the main factors considered by most programs are:

  • I am a permanent, legal resident of the United States or Puerto Rico
  • I am uninsured or my insurance doesn’t cover my medication
  • I meet certain income eligibility requirements

How do I apply for Blenrep patient assistance?

We do everything that we can to take the hassle and stress out of applying for patient assistance programs. Simply start by filling in our enrollment application. We will ask for details about your healthcare provider, your insurance, and your household income. This information is required by the pharmaceutical companies you are applying to for assistance. We may also be able to help you access patient assistance for other medications that you have been prescribed, so be sure to tell us about any medications you are taking as well as Blenrep.

NiceRx will review the information you have provided, and if we determine that you may be eligible for assistance, we will seek to enroll you in the Blenrep patient assistance program. We will handle the enrollment process for you by working with your healthcare provider and preparing all the required paperwork for your doctor to sign. We will also request your Blenrep medication refills on your behalf for up to 1 year once you are enrolled in the program.

Is NiceRx a Blenrep coupons provider?

At NiceRx, we help eligible individuals access the Blenrep patient assistance program. This means that we are not a Blenrep coupon, a Blenrep discount card, or a Blenrep copay card provider. We do not offer any medication trial offers or free Blenrep samples.

Can NiceRx help me get Blenrep if I have insurance?

We may be able to help you if you have insurance, including if your insurance company will not pay for your Blenrep medication, or you have a high copay or coinsurance responsibility. We may even be able to assist if you do not have insurance. Please fill in our enrollment application to find out more.

What is Blenrep?

Blenrep is an FDA (Food and Drug Administration) approved medication manufactured by GlaxoSmithKline (GSK). It is a B-cell maturation antigen (BCMA)-directed antibody and microtubule inhibitor conjugate indicated for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least 4 prior therapies including an anti-CD38 monoclonal antibody, a proteasome inhibitor, and an immunomodulatory agent.

What doses of Blenrep are available?

Blenrep is available for injection: 100 mg as a lyophilized powder in a single-dose vial for reconstitution and further dilution.

Due to the risk of ocular toxicity, Blenrep is only available through a restricted program called the Blenrep REMS (Risk Evaluation and Mitigation Strategy).

  • You must read and agree to all of the instructions in the Blenrep REMS before starting treatment. You must be enrolled in the Blenrep REMS and follow the requirements for eye exams in order to receive your treatment
  • Please see the full Prescribing Information, including Boxed Warning and Medication Guide

Blenrep active ingredients

Belantamab mafodotin-blmf is an antibody-drug conjugate (ADC). The antibody part is directed against BCMA, a protein released on normal B lymphocytes and multiple myeloma cells. The small molecule part is MMAF, a microtubule inhibitor. After binding to BCMA, belantamab mafodotin-blmf is internalized, followed by the release of MMAF via proteolytic cleavage. The released MMAF intracellularly disrupts the microtubule network, leading to cell cycle arrest and eventual death.

Blenrep side effects

The most common side effects of Blenrep in clinical trials include:

  • Keratopathy (corneal epithelium change on eye exam)
  • Decreased visual acuity
  • Nausea, blurred vision
  • Pyrexia
  • Infusion-related reactions
  • Tiredness

In rare instances, Blenrep can cause more serious side effects. These can include:

  • Dry eyes, severe vision loss, and corneal ulcer – patients are advised to use preservative-free lubricant eye drops and to avoid wearing contact lenses unless directed to do so by an ophthalmologist
  • Signs of bleeding in the brain – weakness, dizziness, confusion, numbness or tingling on one side of the body, loss of movement in your face
  • Laboratory abnormalities – decreased platelets, lymphocytes, hemoglobin, neutrophils. Increased creatinine increased, and gamma-glutamyl transferase increased
  • Thrombocytopenia

Your healthcare professional will assess the benefits of using Blenrep against your risk of side effects.

Patients are encouraged to report negative side effects or adverse reactions of Blenrep to the FDA. Visit, or call 1-800-FDA-1088.
