5 Warnings And Precautions


  • Neurologic Toxicity: Can cause serious neurologic toxicity, including Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS). Monitor for neurologic toxicity; withhold or permanently discontinue based on severity. (5.2)
  • Serious Infections: Can cause serious or fatal infections. Monitor patients for signs and symptoms of infection and treat appropriately. (5.3)
  • Tumor Flare: Can cause serious tumor flare reactions. Monitor patients at risk for complications of tumor flare. (5.4)
  • Embryo-Fetal Toxicity: May cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus and to use effective contraception. (5.5, 8.1, 8.3)

5.1Cytokine Release Syndrome


COLUMVI can cause serious and fatal cytokine release syndrome (CRS) [see Adverse Reactions (6.1)].

Among 145 patients who received COLUMVI, CRS occurred in 70%, with Grade 1 CRS developing in 52% of all patients, Grade 2 in 14%, Grade 3 in 2.8%, and Grade 4 in 1.4%. The most common manifestations of CRS included fever, tachycardia, hypotension, chills, and hypoxia.

CRS occurred in 56% of patients after the 2.5 mg dose of COLUMVI, 35% after the 10 mg dose, 29% after the initial 30 mg target dose, and 2.8% after subsequent doses. With the first step-up dose of COLUMVI, the median time to onset of CRS (from the start of infusion) was 14 hours (range: 5 to 74 hours). CRS after any dose resolved in 98% of cases, with a median duration of CRS of 2 days (range: 1 to 14 days). Recurrent CRS occurred in 34% of all patients. CRS can first occur with the 10 mg dose; of 135 patients treated with the 10 mg dose of COLUMVI, 15 patients (11%) experienced their first CRS event with the 10 mg dose, of which 13 events were Grade 1, 1 event was Grade 2, and 1 event was Grade 3.

Administer COLUMVI in a facility equipped to monitor and manage CRS. Initiate therapy according to the COLUMVI step-up dosing schedule to reduce the risk of CRS, administer pretreatment medications, and ensure adequate hydration [Dosage and Administration (2.3)]. Patients should be hospitalized during and for 24 hours after completing infusion of the 2.5 mg step-up dose. Patients who experienced any grade CRS during the 2.5 mg step-up dose should be hospitalized during and for 24 hours after completion of the 10 mg step-up dose. For subsequent doses, patients who experienced Grade ≥ 2 CRS with the previous infusion should be hospitalized during and for 24 hours after the next COLUMVI infusion [see Dosage and Administration (2.1 and 2.2)].

At the first sign of CRS, immediately evaluate patients for hospitalization, manage per current practice guidelines, and administer supportive care; withhold or permanently discontinue COLUMVI based on severity [see Dosage and Administration (2.4)].

5.2Neurologic Toxicity


COLUMVI can cause serious and fatal neurologic toxicity, including Immune Effector Cell-Associated Neurotoxicity (ICANS) [see Adverse Reactions (6.1)].

Among 145 patients who received COLUMVI, the most frequent neurologic toxicities of any grade were headache (10%), peripheral neuropathy (8%), dizziness or vertigo (7%), and mental status changes (4.8%, including confusional state, cognitive disorder, disorientation, somnolence, and delirium). Grade 3 or higher neurologic adverse reactions occurred in 2.1% of patients and included somnolence, delirium, and myelitis. Cases of ICANS of any grade occurred in 4.8% of patients.

Coadministration of COLUMVI with other products that cause dizziness or mental status changes may increase the risk of neurologic toxicity. Optimize concomitant medications and hydration to avoid dizziness or mental status changes. Institute fall precautions as appropriate.

Monitor patients for signs and symptoms of neurologic toxicity, evaluate, and provide supportive therapy; withhold or permanently discontinue COLUMVI based on severity [see Dosage and Administration (2.4)].

Evaluate patients who experience neurologic toxicity such as tremors, dizziness, or adverse reactions that may impair cognition or consciousness promptly, including potential neurology evaluation. Advise affected patients to refrain from driving and/or engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, until the neurologic toxicity fully resolves.

5.3 Serious Infections


COLUMVI can cause serious or fatal infections [see Adverse Reactions (6.1)].

Serious infections were reported in 16% of patients, including Grade 3 or 4 infections in 10%, and fatal infections in 4.8% of patients. Grade 3 or higher infections reported in ≥ 2% of patients were COVID-19 infection (6%), including COVID-19 pneumonia, and sepsis (4.1%). Febrile neutropenia occurred in 3.4% of patients.

COLUMVI should not be administered to patients with an active infection. Administer antimicrobial prophylaxis according to guidelines. Monitor patients before and during COLUMVI treatment for infection and treat appropriately. Withhold or consider permanent discontinuation of COLUMVI based on severity [see Dosage and Administration (2.4)].

5.4 Tumor Flare


COLUMVI can cause serious tumor flare [see Adverse Reactions (6.1)]. Manifestations include localized pain and swelling at the sites of the lymphoma lesions and/or dyspnea from new pleural effusions.

Tumor flare was reported in 12% of patients who received COLUMVI, including Grade 2 tumor flare in 4.8% of patients and Grade 3 tumor flare in 2.8%. Recurrent tumor flare occurred in two (12%) of the affected patients. Most tumor flare events occurred during Cycle 1, with a median time to first onset of 2 days (range: 1 to 16 days) after the first dose of COLUMVI. The median duration was 3.5 days (range: 1 to 35 days).

Patients with bulky tumors or disease located in close proximity to airways or a vital organ should be monitored closely during initial therapy. Monitor for signs and symptoms of compression or obstruction due to mass effect secondary to tumor flare, and institute appropriate treatment. Withhold COLUMVI until tumor flare resolves [see Dosage and Administration (2.4)].

5.5Embryo-Fetal Toxicity


Based on its mechanism of action, COLUMVI may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with COLUMVI and for 1 month after the last dose [see Use in Specific Populations (8.1, 8.3)].

6adverse Reactions


The following clinically significant adverse reactions are described elsewhere in the labeling:


The most common (≥ 20%) adverse reactions, excluding laboratory abnormalities, are cytokine release syndrome, musculoskeletal pain, rash, and fatigue. The most common (≥ 20%) Grade 3 to 4 laboratory abnormalities are lymphocyte count decreased, phosphate decreased, neutrophil count decreased, uric acid increased, and fibrinogen decreased. (6.1)

6.1Clinical Trials Experience


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


Relapsed or Refractory DLBCL, NOS or LBCL Arising from Follicular Lymphoma


Study NP30179

The safety of COLUMVI was evaluated in Study NP30179, a multi-cohort, multicenter, single-arm clinical trial that included 154 adult patients with relapsed or refractory large B-cell lymphoma (LBCL) after two or more lines of systemic therapy [see Clinical Studies (14.1)]. The trial required an ECOG performance status of 0 or 1, absolute neutrophil count ≥ 1,500/µL, platelet count ≥ 75,000/µL independent of transfusion, serum creatinine ≤ 1.5 × upper limit of normal (ULN) or creatinine clearance (CLcr) ≥ 50 mL/min, and hepatic transaminases ≤ 3 × ULN. The trial excluded patients with active or previous central nervous system (CNS) lymphoma or CNS disease, acute infection, recent infection requiring intravenous antibiotics, or prior allogeneic hematopoietic stem cell transplantation (HSCT).

Patients received pretreatment with a single dose of obinutuzumab on Day 1 of Cycle 1 (seven days prior to start of COLUMVI). Following premedication, COLUMVI was administered by intravenous infusion according to the step-up dosing schedule with 2.5 mg on Day 8 of Cycle 1, and 10 mg on Day 15 of Cycle 1. Patients received the 30 mg COLUMVI dose by intravenous infusion on Day 1 of subsequent cycles for a maximum of 12 cycles (including step-up dosing). Each cycle was 21 days. Patients were hospitalized during and for 24 hours following completion of at least the first step-up dose.

Of the 154 patients who initiated study treatment, 145 received COLUMVI; nine patients (6%) did not receive COLUMVI due to infection, progressive disease, or patient decision. Patients received a median of 5 cycles of COLUMVI with 30% receiving all 12 cycles of COLUMVI.

Of patients who received COLUMVI, the median age was 66 years (range: 21 to 90 years); 66% were male; 77% were White, 4.8% were Asian, 1.4% were Black or African American, 6% were Hispanic or Latino. The main diagnoses were DLBCL, NOS and LBCL arising from follicular lymphoma.

Serious adverse reactions occurred in 48% of patients who received COLUMVI. Serious adverse reactions in ≥ 2% of patients included CRS, COVID-19 infection, sepsis, and tumor flare. Fatal adverse reactions occurred in 5% of patients from COVID-19 infection (3.4%), sepsis (1.4%), and delirium (0.6%).

Adverse reactions led to permanent discontinuation of COLUMVI in 7% of patients, including from infection, delirium, neutropenia, and CRS. Adverse reactions led to dose interruptions of COLUMVI in 19% of patients, most frequently (≥ 2%) from neutropenia and thrombocytopenia.

The most common (≥ 20%) adverse reactions, excluding laboratory terms, were CRS, musculoskeletal pain, rash, and fatigue. The most common Grade 3 to 4 laboratory abnormalities (≥ 20%) were lymphocyte count decreased, phosphate decreased, neutrophil count decreased, uric acid increased, and fibrinogen decreased.

7 Drug Interactions


For certain CYP substrates where minimal concentration changes may lead to serious adverse reactions, monitor for toxicities or drug concentrations of such CYP substrates when coadministered with COLUMVI.

Glofitamab-gxbm causes the release of cytokines [see Clinical Pharmacology (12.2)] that may suppress the activity of CYP enzymes, resulting in increased exposure of CYP substrates. Increased exposure of CYP substrates is more likely to occur after the first dose of COLUMVI on Cycle 1 Day 8 and up to 14 days after the first 30 mg dose on Cycle 2 Day 1 and during and after CRS [see Warnings and Precautions (5.1)].

8 Use In Specific Populations



Lactation: Advise not to breastfeed. (8.2)

8.1 Pregnancy


Risk Summary

Based on its mechanism of action COLUMVI may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on the use of COLUMVI in pregnant women to evaluate for a drug-associated risk. No animal reproductive and developmental toxicity studies have been conducted with glofitamab-gxbm.

Glofitamab-gxbm causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. In addition, based on expression of CD20 on B cells and the finding of B-cell depletion in non-pregnant animals, glofitamab-gxbm can cause B-cell lymphocytopenia in infants exposed to glofitamab-gxbm in-utero. Human immunoglobulin G (IgG) is known to cross the placenta; therefore, COLUMVI has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

8.2 Lactation



Risk Summary

There are no data on the presence of glofitamab-gxbm in human milk or the effects on the breastfed child or milk production. Because human IgG is present in human milk, and there is potential for glofitamab-gxbm absorption leading to B-cell depletion, advise women not to breastfeed during treatment with COLUMVI and for 1 month after the last dose of COLUMVI.

8.3Females and Males of Reproductive Potential


COLUMVI may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].


Pregnancy Testing

Verify pregnancy status in females of reproductive potential prior to initiating COLUMVI.


Contraception


Females

Advise female patients of reproductive potential to use effective contraception during treatment with COLUMVI and for 1 month after the last dose of COLUMVI [see Use in Specific Populations (8.1)].

8.4Pediatric Use


The safety and efficacy of COLUMVI in pediatric patients have not been established.

8.5Geriatric Use


Of the 145 patients with relapsed or refractory LBCL who received COLUMVI in study NP30179, 55% were 65 years of age or older, and 23% were 75 years of age or older. There was a higher rate of fatal adverse reactions, primarily from COVID-19, in patients 65 years of age or older compared to younger patients [see Adverse Reactions (6.1)]. No overall differences in efficacy were observed between patients 65 years of age or older and younger patients.

11description


Glofitamab-gxbm is a bispecific CD20-directed CD3 T-cell engager. It is a recombinant humanized anti-CD20 anti-CD3É› bispecific immunoglobulin G1 (IgG1) monoclonal antibody produced in Chinese hamster ovary (CHO) cells. Glofitamab-gxbm has an approximate molecular weight of 197 kDa.

COLUMVI (glofitamab-gxbm) injection is a sterile, preservative-free, colorless, clear solution supplied in single-dose vials for intravenous infusion.

COLUMVI is supplied in 2.5 mg/2.5 mL and 10 mg/10 mL single-dose vials at a concentration of 1 mg/mL. Each mL of solution contains 1 mg glofitamab-gxbm, histidine (0.63 mg), histidine hydrochloride monohydrate (3.34 mg), methionine (1.49 mg), polysorbate 20 (0.5 mg), sucrose (82.15 mg), and Water for Injection, USP, at pH 5.5.

12clinical Pharmacology


12.1Mechanism of Action


Glofitamab-gxbm is a bispecific antibody that binds to CD20 expressed on the surface of B cells, and to CD3 receptor expressed on the surface of T cells. Glofitamab-gxbm causes T-cell activation and proliferation, secretion of cytokines, and the lysis of CD20-expressing B cells. Glofitamab-gxbm showed anti-tumor activity in vivo in mouse models of DLBCL.

12.2 Pharmacodynamics



Circulating B Cell Count

Peripheral B cell counts decreased to undetectable levels (< 5 cells/microliter) in 86.5% of patients by Cycle 1 Day 7 after obinutuzumab pretreatment of 1,000 mg on Cycle 1 Day 1, and in 88.2% of patients by Cycle 1 Day 10 after the first glofitamab-gxbm dose of 2.5 mg on Cycle 1 Day 8.


Cytokine Concentrations

Plasma concentrations of cytokines (IL-2, IL-6, IL-10, TNF-α, and IFN-γ) were measured and transient elevation of cytokines was observed at doses of 0.045 mg and above. After administration of the recommended dosage of COLUMVI, the highest elevation of cytokines was generally observed within 6 hours after the first glofitamab-gxbm dose of 2.5 mg on Cycle 1 Day 8. The elevated cytokine levels generally returned to baseline within 48 hours after the first 30 mg dose on Cycle 2 Day 1.

12.3Pharmacokinetics


The pharmacokinetics of glofitamab-gxbm was determined following pretreatment with a single dose of obinutuzumab of 1,000 mg and the pharmacokinetic parameters are presented as geometric mean (CV%) unless otherwise specified. Glofitamab-gxbm exposure increased dose-proportionally over the dose range from 0.005 to 30 mg (0.000167 to 1 time the recommended treatment dosage). Glofitamab-gxbm exposure parameters are summarized in Table 10 for the approved recommended dosage of COLUMVI.

AUCtau (day∙mcg/mL) Cmax (mcg/mL) Ctrough (mcg/mL)
Data presented as geometric mean (CV%). AUCtau = area under the concentration-time curve over one 21-day cycle; Cmax = maximum glofitamab-gxbm concentration; Ctrough = glofitamab-gxbm concentration prior to next dose; CV = geometric coefficient of variation.
First full 30 mg dose 44.5 (55%) 9.41 (27%) 0.52 (83%)
Steady stateSteady state values are approximated at Cycle 6 (week 18). 30 mg dose 48.6 (33%) 9.44 (26%) 0.59 (67%)


Distribution

The glofitamab-gxbm total volume of distribution is 5.6 L (24%).


Elimination

At steady state, the glofitamab-gxbm terminal half-life is 7.6 days (24%) and the clearance is 0.617 L/day (33%).


Metabolism

Glofitamab-gxbm is expected to be metabolized into small peptides by catabolic pathways.


Specific Populations

No clinically significant changes in the pharmacokinetics of glofitamab-gxbm were observed based on age (21 to 90 years), body weight (31 to 148 kg), sex, mild to moderate renal impairment (CLcr 30 to < 90 mL/min as estimated by Cockcroft-Gault formula) and mild hepatic impairment (total bilirubin > ULN to ≤ 1.5 × ULN or AST > ULN).

The effects of severe renal impairment (CLcr 15 to < 30 mL/min), end-stage renal disease (CLcr < 15 mL/min), or moderate to severe hepatic impairment (total bilirubin > 1.5 × ULN and any AST), and race/ethnicity on the pharmacokinetics of glofitamab-gxbm are unknown.


Drug Interaction Studies

No clinical studies evaluating the drug interaction potential of glofitamab-gxbm have been conducted.

12.6Immunogenicity


The observed incidence of antidrug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the study described below with the incidence of ADA in other studies, including those of glofitamab-gxbm.

During treatment in Study NP30179 (up to 9 months) [see Clinical Studies (14.1)], using an enzyme-linked immunosorbent assay (ELISA), the incidence of anti-glofitamab antibody formation was 1.1% (5/448) in patients treated with COLUMVI. Because of the low occurrence of ADAs, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of glofitamab-gxbm is unknown.

13nonclinical Toxicology


13.1Carcinogenesis, Mutagenesis, Impairment of Fertility


No carcinogenicity or genotoxicity studies have been conducted with glofitamab-gxbm.

Fertility studies have not been conducted with glofitamab-gxbm.

14clinical Studies


14.1Relapsed or Refractory DLBCL, NOS or LBCL Arising from Follicular Lymphoma


The efficacy of COLUMVI was evaluated in Study NP30179 (NCT03075696), an open-label, multicenter, multicohort, single-arm clinical trial that included patients with relapsed or refractory LBCL after two or more lines of systemic therapy. The trial required an ECOG performance status of 0 or 1, absolute neutrophil count ≥ 1,500/µL, platelet count ≥ 75,000/µL independent of transfusion, serum creatinine ≤ 1.5 × ULN or CLcr ≥ 50 mL/min, and hepatic transaminases ≤ 3 × ULN. The trial excluded patients with active or previous CNS lymphoma or CNS disease, acute infection, recent infection requiring intravenous antibiotics, or prior allogeneic HSCT.

Following pretreatment with obinutuzumab on Cycle 1 Day 1, patients received COLUMVI by intravenous infusion, starting with a 2.5 mg step-up dose on Cycle 1 Day 8, followed by a 10 mg step-up dose on Cycle 1 Day 15, then 30 mg on Cycle 2 Day 1 and on Day 1 of each subsequent cycle. The cycle length was 21 days. COLUMVI was administered for up to 12 cycles unless patients experienced progressive disease or unacceptable toxicity.

The efficacy population consists of 132 patients with de novo DLBCL, NOS (80%) or LBCL arising from follicular lymphoma (20%) who received at least one dose of COLUMVI. The median age was 67 years (range: 21 to 90 years), 64% were male, 77% were White, 4.5% were Asian, 0.8% were Black or African American, 5% were Hispanic or Latino. The median number of prior lines of systemic therapy was 3 (range: 2 to 7). Most patients (83%) had refractory disease to the last therapy, 55% had primary refractory disease, 30% had received CAR-T cell therapy, and 19% had received autologous HSCT.

Efficacy was based on objective response rate (ORR) and duration of response (DOR), as determined by an Independent Review Committee (IRC) using the 2014 Lugano criteria.

Efficacy results are summarized in Table 11. The median time to first response was 42 days (range: 31 to 178 days). Among responders, the estimated median follow-up for DOR was 11.6 months.

MEDICATION GUIDECOLUMVIâ„¢ (ko-loom-vee)(glofitamab-gxbm)injection, for intravenous infusion
This Medication Guide has been approved by the U.S. Food and Drug Administration. Issued: 6/2023
What is the most important information I should know about COLUMVI?
COLUMVI can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with COLUMVI, and can also be serious and lead to death.
  • Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:
  • fever of 100.4°F (38°C) or higher
  • chills or shaking
  • fast or irregular heartbeat
  • dizziness or light-headedness
  • trouble breathing
  • shortness of breath
  • Due to the risk of CRS, you will receive COLUMVI on a "step-up dosing schedule".
    • A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
    • You will start the COLUMVI step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of COLUMVI on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
    • You will receive your first full dose of COLUMVI a week after the second step-up dose (this will be Day 1 of Cycle 2).
    • If your dose of COLUMVI is delayed for any reason, you may need to repeat the "step-up dosing schedule".
    • If you had more than mild CRS with your previous dose of COLUMVI, you should be hospitalized during and for 24 hours after receiving your next dose of COLUMVI.
    • Before each dose of COLUMVI, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.
    • See "How will I receive COLUMVI?" for more information about how you will receive COLUMVI.
  • Your healthcare provider will monitor you for CRS during treatment with COLUMVI and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with COLUMVI if you have severe side effects.
  • Carry the COLUMVI Patient Wallet Card with you at all times and show it to all of your healthcare providers. The COLUMVI Patient Wallet Card uls the signs and symptoms of CRS you should get emergency medical help for right away.
See "What are the possible side effects of COLUMVI? " for more information about side effects.
What is COLUMVI? COLUMVI is a prescription medicine used to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.It is not known if COLUMVI is safe and effective in children.
Before receiving COLUMVI, tell your healthcare provider about all of your medical conditions, including if you:
  • have an infection
  • have kidney problems
  • are pregnant or plan to become pregnant. COLUMVI may harm your unborn baby. Females who are able to become pregnant:
    • Your healthcare provider should do a pregnancy test before you start treatment with COLUMVI.
    • You should use effective birth control (contraception) during treatment and for 1 month after your last dose of COLUMVI. Talk to your healthcare provider about what birth control method is right for you during this time.
    • Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with COLUMVI.
  • are breastfeeding or plan to breastfeed. It is not known if COLUMVI passes into your breastmilk. Do not breastfeed during treatment and for 1 month after your last dose of COLUMVI.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
How will I receive COLUMVI?
  • COLUMVI will be given to you by your healthcare provider by infusion through a needle placed in your vein (intravenous infusion).
  • Your COLUMVI treatment schedule is divided into cycles that are 21 days (3 weeks) long.
  • On Day 1 of Cycle 1, your healthcare provider will give you a single dose of a medicine called obinutuzumab by intravenous infusion. You will then receive COLUMVI on Day 8 and Day 15 of Cycle 1. Starting with Cycle 2, you will receive COLUMVI 1 time every three weeks.
Your healthcare provider will decide how many treatment cycles you will receive of COLUMVI. See "What is the most important information I should know about COLUMVI?" for more information about how you will receive COLUMVI.
What should I avoid while receiving COLUMVI?Do not drive, operate heavy machinery, or do other dangerous activities if you develop dizziness, confusion, shaking (tremors), sleepiness, or any other symptoms that impair consciousness until your signs and symptoms go away. These may be signs and symptoms of neurologic problems.See " What are the possible side effects of COLUMVI?" for more information about signs and symptoms of neurologic problems.
What are the possible side effects of COLUMVI?
COLUMVI may cause serious side effects, including:
  • Cytokine Release Syndrome. See "What is the most important information I should know about COLUMVI?"
  • Neurologic problems. COLUMVI can cause serious neurologic problems that may lead to death. Your healthcare provider will monitor you for neurologic problems during treatment with COLUMVI.
