Pharmacological Class

GD2-binding monoclonal antibody.

How Supplied

Single-dose vial (10mL)—1

Generic Availability

NO

Mechanism of Action

Naxitamab-gqgk binds to the glycolipid GD2. GD2 is a disialoganglioside that is overexpressed on neuroblastoma cells and other cells of neuroectodermal origin, including the central nervous system and peripheral nerves. In vitro, naxitamab-gqgk was able to bind to cell surface GD2 and induce complement dependent cytotoxicity (CDC) and antibody dependent cell-mediated cytotoxicity (ADCC).

Danyelza Indications

Indications

In combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) for the treatment of patients with relapsed or refractory high-risk neuroblastoma in the bone or bone marrow who have demonstrated a partial response, minor response, or stable disease to prior therapy.

Danyelza Dosage and Administration

Adults and Children

<1yr: not established. Premedicate with an antihistamine, acetaminophen, an H2 antagonist, antiemetic, and/or corticosteroid prior to or during infusions, as appropriate: see full labeling. First infusion (Cycle 1, Day 1): give by IV infusion over 60mins. Subsequent infusions: give by IV over 30–60mins, as tolerated. ≥1yr: 3mg/kg/day (max 150mg/day) on Days 1, 3, and 5 of each 4-week cycle until complete or partial response, followed by 5 additional cycles every 4 weeks; subsequent cycles may be repeated every 8 weeks. Days -4 to 0: administer GM-CSF 250mcg/m2/day by SC inj starting 5 days prior to Danyelza infusion; Days 1 to 5: administer GM-CSF 500mcg/m2/day by SC inj at least 1hr prior to Danyelza infusion on Days 1, 3, and 5.

Danyelza Warnings/Precautions

Warnings/Precautions

Have resuscitative medications and equipment available. Risk of serious infusion-related reactions. Monitor closely during and for at least 2 hours after completion of each infusion; reduce infusion rate, interrupt, or permanently discontinue based on severity; treat appropriately. Risk of severe neurotoxicity. Risk of severe hypotension in patients with pre-existing cardiac disease. Monitor for myocarditis esp. in adolescent patients during treatment; withhold, reduce dose, or permanently discontinue based on severity.

Uncontrolled hypertension: do not initiate. Monitor BP during and at least daily on Days 1–8 of each cycle; evaluate for complications (including RPLS); interrupt infusion, resume at a reduced rate, or permanently discontinue based on the severity. Monitor postural BP prior to initiating and as clinically indicated in patients with symptoms of orthostatic hypotension; withhold, reduce dose, or permanently discontinue based on severity. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for 2 months after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for 2 months after the last dose).
