Columvi (glofitamab) is an injectable medication used to treat certain types of large B-cell lymphoma (LBCL) in adults who have had at least two other treatments that didn’t work or stopped working. It's given as an intravenous (IV) infusion over a fixed treatment period, typically completed in about 8.5 months. Columvi (glofitamab) is a bispecific monoclonal antibody that helps your immune system find and destroy cancer cells. Common side effects include low blood cell counts, muscle pain, tiredness, and a serious reaction called cytokine release syndrome (CRS).
Columvi (glofitamab) is a bispecific T-cell engager (BiTE), which is a type of monoclonal antibody that’s designed to bind to two different targets. One side of the antibody attaches to CD20, a protein on cancer cells, while the other side binds to CD3, a protein on T-cells in your immune system. By connecting these two cells, Columvi (glofitamab) brings T-cells close to the cancer cells, helping the immune system attack and destroy the cancer cells.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

No, Columvi (glofitamab) isn’t chemotherapy. Unlike traditional chemotherapy, which attacks all fast-growing cells, Columvi (glofitamab) works more specifically at cancer cells. It’s a type of immunotherapy that helps your immune system find and destroy cancer cells by connecting certain immune cells to the cancer.
Yes, Columvi (glofitamab) is FDA approved under the accelerated approval pathway. This means the FDA approved the medication based on early clinical study results showing it helped some people with relapsed or refractory large B-cell lymphoma (LBCL). Accelerated approval lets the FDA make promising treatments available sooner, especially for serious conditions with limited options. But more studies are still needed to confirm how well it works long term.
Columvi (glofitamab) treatment is designed to last about 8.5 months, given 13 infusions (including the step-up doses in cycle 1). But the total treatment time might be longer if you have dose delays or need to pause treatment due to serious side effects. You can receive the medication for up to 12 treatment cycles, but it might be stopped earlier if your cancer worsens or if you have side effects that are too severe to continue.
Columvi (glofitamab) can start working within the first few treatment cycles, but it can vary from person to person. In clinical studies, some people saw a response in as little as 4 to 5 weeks, while others took a few months to experience improvement. Your oncology care team will monitor you closely to see how well the treatment is working.
Columvi (glofitamab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Columvi (glofitamab) can cause a reaction called cytokine release syndrome (CRS), which can be serious or even life-threatening. CRS happens when your immune system overreacts to the medication. Symptoms can include headache, chills, fever, low blood pressure, trouble breathing, fast heartbeat, and confusion. CRS usually happens during the “step up” doses, often starting a few hours after your infusion and lasting a few days.
To help reduce your risk, you’ll take premedications before your Columvi (glofitamab) doses and follow a “step-up” dosing process. You’ll need to stay in the hospital during and for 24 hours after your first “step-up” dose and again after the second “step-up” dose if you had any CRS symptoms. If you had a moderate or serious reaction before, you’ll also need to stay in the hospital for future doses. If you start to feel sick after at any point, get medical help right away — your treatment might need to be paused or stopped depending on how serious the reaction is.
Columvi (glofitamab) can cause serious nervous system problems, including a condition called immune effector cell-associated neurotoxicity syndrome (ICANS). Tell your care team immediately if you have symptoms like headache, tingling or numbness, dizziness, confusion, sleepiness, or trouble focusing. If you have any changes in how you think or stay alert, don’t drive or use heavy equipment until you feel back to normal.
Columvi (glofitamab) can cause serious or even deadly infections, including COVID-19 pneumonia and sepsis. Your oncologist might prescribe antibiotics or antivirals to help prevent infections while you’re getting treatment. Contact your care team right away if you have any signs or symptoms of infection such as fever, body aches, chills, or cough.
Columvi (glofitamab) can cause a reaction called tumor flare, which can be serious. Tumor flare can lead to pain or swelling where your cancer is located, and sometimes trouble breathing if fluid builds up near your lungs. This usually happens during the first cycle of treatment, often starting around 2 days after the first “step-up” dose and lasting a few days.
Based on the way Columvi (glofitamab) works, it might cause harm to an unborn baby. If you’re able to get pregnant, use birth control while taking this medication and for 1 month after the last dose. Let your oncologist know if you’re pregnant or thinking about becoming pregnant while taking Columvi (glofitamab).
Before starting Columvi (glofitamab), you’ll take a one-time dose of another medication called Gazyva (obinutuzumab).
After that, you’ll begin Columvi (glofitamab) on a step-up dosing schedule, which means the dose will start low and gradually increase to the full dose. Each dose is given as an injection through the vein (intravenous, IV), and each treatment cycle lasts 21 days.
