Pronunciation: mon-JOO-vee
Generic name: tafasitamab
Dosage form: single-dose vial for intravenous infusion (200 mg)
Drug class: CD19 monoclonal antibodies
What is Monjuvi?
Monjuvi is used to treat relapsed or refractory diffuse large B-cell lymphoma (DLBCL) or relapsed or refractory follicular lymphoma (FL). It is given as an intravenous infusion by a healthcare provider, two to five times during a 28-day cycle.
Monjuvi is a targeted immunotherapy treatment that works by binding to CD19 markers expressed on the surface of pre-B and mature-B lymphocytes and several B-cell cancers, including DLBCL and FL. Once bound, Monjuvi signals the immune system to attack and destroy these cells. Monjuvi belongs to the drug class called CD19-directed cytolytic antibodies.
Monjuvi (tafasitamab-cxix) gained FDA approval on July 31, 2020, for DLBCL. Approval was extended on June 18, 2025, to include FL. There is no generic.
FDA approvals and uses
Monjuvi is FDA approved for adults with:
- Relapsed or refractory diffuse large B-cell lymphoma (DLBCL), not otherwise specified, including DLBCL arising from low-grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT), in combination with lenalidomide
- This approval is under the accelerated approval designation, and continued approval may be contingent upon a continued clinical benefit being shown in confirmatory trials.
- Relapsed or refractory follicular lymphoma (FL) in combination with lenalidomide and rituximab.
- Not indicated for relapsed or refractory marginal zone lymphoma outside of controlled clinical trials.
Monjuvi FDA approval was granted to Incyte and MorphoSys AG based on the following positive results from the clinical trial L-MIND (NCT02399085), an open-label Phase 2 study, which reported
- 55% of Monjuvi patients reach remission at 1 year
- 37% had a complete remission
- 18% had a partial remission.

Before taking
Before you receive Monjuvi, tell your healthcare provider about all of your medical conditions, including if you:
- have an active infection or have had one recently
- are pregnant or plan to become pregnant
- are breastfeeding or plan to breastfeed.
Pregnancy
Monjuvi may harm your unborn baby. You should not become pregnant during treatment with Monjuvi. Do not receive treatment with Monjuvi in combination with lenalidomide if you are pregnant because lenalidomide can cause birth defects and death of your unborn baby.
- You should use an effective method of birth control (contraception) during treatment and for 3 months after your last dose of Monjuvi.
- Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with Monjuvi.
Monjuvi is used in combination with lenalidomide. Both men and women using lenalidomide must use effective birth control. Even one dose can cause severe, life-threatening birth defects or death of a baby if the mother or the father is taking lenalidomide at the time of conception or during pregnancy. You should also read the lenalidomide Medication Guide for important information about pregnancy, contraception, blood and sperm donation.
Breastfeeding
It is not known if Monjuvi passes into your breastmilk. Do not breastfeed during treatment and for at least 3 months after your last dose of Monjuvi.
How is Monjuvi given?
Monjuvi will be given to you by your healthcare provider as an intravenous (IV) infusion into one of your veins.

- This medicine must be given slowly, and the infusion can take up to 2.5 hours to complete.
Each treatment cycle of Monjuvi lasts for 28 days.
- Monjuvi will be given 2 to 5 times during the 28-day cycle, depending on the type of cancer you have or how many weeks through your treatment you are.
- Your healthcare provider will decide how many treatments you need.
- Your healthcare provider may need to delay or completely stop treatment with Monjuvi if you have severe side effects.
- If you miss any appointments, call your healthcare provider as soon as possible to reschedule your appointment.
