5.1 Cytokine Release SyndromeCOLUMVI can cause serious and fatal cytokine release syndrome (CRS)
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
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

COLUMVI is indicated for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS) or large B-cell lymphoma (LBCL) arising from follicular lymphoma, after two or more lines of systemic therapy.
This indication is approved under accelerated approval based on response rate and durability of response
14.1 Relapsed or Refractory DLBCL, NOS or LBCL Arising from Follicular LymphomaThe 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
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 12. 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.

,2.6 Preparation of 2.5 mg Dose into an Intravenous SyringeThis section describes the alternative method of preparation of the 2.5 mg dose of COLUMVI into an intravenous syringe. For preparation instructions for all doses into an intravenous infusion bag, see subsection 2.5[see Dosage and Administration (2.5)].Preparation- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. COLUMVI is a colorless clear solution. Discard the vial if the solution is cloudy, discolored, or contains visible particles.
- Use aseptic technique when preparing the COLUMVI diluted solution for intravenous syringe infusion.
Dilution for Intravenous Syringe Infusion (Alternative Method for 2.5 mg Dose Only)- Draw 22.5 mL of 0.9% Sodium Chloride Injection or 0.45% Sodium Chloride Injection into a 30 mL syringe composed of PP (see Table 8).
- Withdraw 2.5 mL of COLUMVI from the vial using a sterile needle into a second syringe (see Table 8). Discard any unused COLUMVI left in the vial.
- Attach a connector to the two syringes and transfer COLUMVI into the 30 mL syringe. The final concentration of COLUMVI should be 0.1 mg/mL.

Draw air into the syringe containing the COLUMVI diluted solution and close.
- Gently invert the syringe to mix the solution, in order to avoid excessive foaming. Do not shake.
- Remove air bubbles from the syringe before administration.
)2.7 Storage and AdministrationStorage of Diluted ProductImmediately use diluted COLUMVI solution. If not used immediately, the diluted solution can be stored:- Refrigerated at 2°C to 8°C (36°F to 46°F) for up to 64 hours, or
- At room temperature up to 25°C (77°F) for up to 4 hours.
Do not freeze the diluted infusion solution.Discard diluted infusion solution if storage time exceeds these limits.COLUMVI Administration- Administer COLUMVI as an intravenous infusion only through a dedicated infusion line that includes a sterile 0.2-micron in-line filter using an intravenous infusion pump or syringe pump. Prime the infusion line with the diluted infusion solution.
- No incompatibilities have been observed with infusion sets with product-contacting surfaces of polyurethane (PUR), PVC, PE, polybutadiene (PBD), polyetherurethane (PEU), polycarbonate (PC), silicone, polytetrafluoroethylene (PTFE), or acrylonitrile butadiene styrene (ABS), and in-line filter membranes composed of polyethersulfone (PES) or polysulfone.
- See Table 1for duration of infusion. The maximum time for the administration of the diluted infusion solution may be extended up to 8 hours (see Table 4).
- To ensure the entire dose of COLUMVI is administered, replace the empty infusion bag or syringe with an infusion bag or syringe containing 0.9% Sodium Chloride Injection or 0.45% Sodium Chloride Injection connected to the same infusion line. Continue the infusion at the same rate until the recommended infusion duration is reached according to Table 1.
- Do not mix COLUMVI with other drugs.
Injection:
- 2.5 mg/2.5 mL (1 mg/mL) clear, colorless solution in a single-dose vial.
- 10 mg/10 mL (1 mg/mL) clear, colorless solution in a single-dose vial.
8.2 LactationThere 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.
