What is Polivy?
Polivy is an injectable targeted treatment that may be used to treat certain patients with moderate-to-high risk diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma (HGBL).
- Polivy is used in combination with other medications, such as rituximab, cyclophosphamide, doxorubicin, and prednisone.
- Polivy is given as an infusion into a vein by a healthcare professional in a clinic or hospital.
Polivy first gained FDA approval on June 10, 2019, under the accelerated approval scheme, but this was upgraded on April 19, 2023, to full approval for previously untreated DLBCL, NOS, and specific patients with HGBL.
Mechanism of action: Polivy
Polivy (polatuzumab vedotin-piiq) is a targeted cancer treatment designed to attack specific cancer cells. It's made up of three parts:
- An antibody that locks onto a specific protein found on B-cells (a type of white blood cell)
- A powerful anti-cancer agent, MMAE
- A linker that connects the antibody and the drug.
Once Polivy finds a B-cell, it attaches and releases the anti-cancer drug inside, killing the cell. While Polivy is designed to target cancer B cells, it can also affect some healthy B cells.
Polivy side effects
The most common side effects of Polivy are:
- diarrhea
- nausea
- decreased appetite
- fatigue or tiredness
- fever
- hair loss
- laboratory abnormalities such as decreased white or red blood cells or high levels of uric acid
- nerve problems
- pneumonia.
Serious side effects and warnings
Polivy may cause the following serious side effects.
Nerve damage (peripheral neuropathy). Your healthcare provider will monitor you for this and modify your dosage of Polivy if necessary. Report numbness or tingling of your hands or feet and muscle weakness to your healthcare provider.
Infusion-related reactions can occur with Polivy, but premedication with certain medicines (such as an antihistamine and an antipyretic) can reduce the risk. Your healthcare provider will monitor you closely during an infusion. Tell your caregiver if you feel feverish, chilled, itchy, light-headed, or have wheezing, chest tightness, or trouble breathing within 24 hours after the injection.
Polivy may also cause bone marrow suppression. Your healthcare provider will conduct regular blood tests to monitor your blood counts and manage them accordingly. Report signs or symptoms of bleeding or an infection immediately.
Polivy may also increase your risk of infections, including serious and unusual bacterial, fungal, or viral infections. Your healthcare provider will monitor you closely for these and your blood will need to be tested often, and further doses may be delayed based on the results. Call your doctor if you have a fever, chills, cough, mouth sores, unusual bleeding or bruising, burning when you urinate, or problems with speech, thought, or muscle movement.
There is a risk of Progressive Multifocal Leukoencephalopathy (PML) (a serious brain infection caused by a virus) associated with Polivy. Call your doctor right away if you have problems with speech, thought, vision, or muscle movement. These symptoms may start gradually and get worse quickly.
Tumor Lysis Syndrome is a life-threatening emergency caused by the release of the contents of tumor cells into the bloodstream. Seek immediate medical attention for symptoms of tumor lysis syndrome such as nausea, vomiting, diarrhea, and lethargy.
May cause liver damage and your healthcare provider will monitor your liver enzymes and bilirubin levels. Report any symptoms such as fatigue, weight loss, right upper stomach discomfort, dark urine, or yellowing of the skin or eyes to your healthcare provider.
Polivy can harm an unborn baby and females who can have children should not become pregnant while taking Polivy.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
