Version July 2025
Dosage guidance:
Clinical considerations: Determine baseline serum cystatin C, urine dipstick (proteinuria), and urine protein-to-creatinine ratio; also consider baseline GFR using an exogenous filtration marker.
Duchenne muscular dystrophy (DMD): Children and Adolescents: IV: 30 mg/kg/dose once weekly. Dosing based on clinical trials in pediatric patients aged 6 to 13 years at study entry (Ref).
Children and Adolescents: There are no dosage adjustments provided in the manufacturer's labeling. Renal clearance is reduced in non-Duchenne muscular dystrophy (DMD) adult patients with renal impairment; patients with known kidney impairment should be closely monitored; however, creatinine is not a reliable measurement of kidney function due to the reduced skeletal muscle mass in patients with DMD. Serum cystatin C, urine dipstick, and urine protein-to-creatinine ratio should be monitored; may consider baseline eGFR using exogenous marker; consult pediatric nephrologist if persistent increase in serum cystatin C or proteinuria develops.
There are no dosage adjustments provided in the manufacturer's labeling (has not been studied).

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Reported adverse reactions are for children and adolescents.
Frequency not defined:
Cardiovascular: Tachycardia
Dermatologic: Excoriation of skin
Gastrointestinal: Abdominal pain, constipation, diarrhea, nausea, vomiting
Hematologic & oncologic: Bruise
Hypersensitivity: Hypersensitivity reaction
Infection: Influenza
Local: Infusion-site pain
Nervous system: Dizziness, falling, headache, pain
Neuromuscular & skeletal: Back pain, bone fracture, sprain
Otic: Otic infection
Respiratory: Cough, nasopharyngitis, oropharyngeal pain, rhinitis
Miscellaneous: Fever
Postmarketing: Hypersensitivity: Anaphylaxis
Serious hypersensitivity (eg, anaphylaxis) to golodirsen or any components of the formulation.
Concerns related to adverse effects:
• Hypersensitivity: Hypersensitivity reactions (including anaphylaxis, rash, pyrexia, pruritus, urticaria, dermatitis, and skin exfoliation) have been reported with use.
• Kidney toxicity: Kidney toxicity, including potentially fatal glomerulonephritis, has been observed with some antisense oligonucleotides. Creatinine may not be a reliable measure of kidney function in patients with Duchenne muscular dystrophy. Refer to nephrologist if persistent increases in serum cystatin C or proteinuria occur.

IV: Must be diluted prior to administration. Administer by IV infusion over 35 to 60 minutes through a 0.2-micron, low protein binding, in-line filter attached to the primary IV tubing; infusion must be completed within 4 hours of preparation. Flush IV access line with NS prior to and after infusion; may consider application of a topical anesthetic cream to the infusion site prior to administration. Do not mix with other medications or infuse other medications concomitantly via the same IV access line. If hypersensitivity reaction occurs, consider slowing the infusion or interrupting therapy. If a dose is missed, administer as soon as possible after the scheduled time.
Rate adjustment for hypersensitivity reactions during infusion : Institute appropriate therapy to manage hypersensitivity reaction(s); consider slowing golodirsen infusion or interrupting therapy; in some cases, discontinuation may be necessary.
IV: Dilution required prior to administration. Administer by IV infusion over 35 to 60 minutes immediately after dilution through a 0.2-micron, low protein-binding, in-line filter attached to the primary IV tubing; complete infusion within 4 hours (stable for 4 hours at room temperature). Use of a topical anesthetic cream on the infusion site may be considered prior to administration. Flush IV access line with NS before and after infusion. Do not mix with other medications or infuse other medications concomitantly via the same IV access line. Discard unused portion.
Store at 2°C to 8°C (36°F to 46°F) in original carton to protect from light. Do not freeze. Diluted solution may be stored for up to 24 hours at 2°C to 8°C (36°F to 46°F).
Treatment of Duchenne muscular dystrophy (DMD) in patients who have a confirmed mutation of the DMD gene that is amenable to exon 53 skipping (FDA approved in pediatric patients [age not specified] and adults).
Note: Indication received accelerated approval based on an increase in skeletal muscle dystrophin production in initial trials; continued approval may be contingent upon confirmatory trials.
Golodirsen may be confused with Goldenseal, Golden Seal, gold sodium thiomalate.
None known.
Note: Interacting drugs may not be individually listed below if they are part of a group interaction (eg, individual drugs within “CYP3A4 Inducers [Strong]” are NOT listed). For a complete list of drug interactions by individual drug name and detailed management recommendations, use the drug interactions program
There are no known significant interactions.
Animal reproduction studies or studies in females have not been conducted.
GFR using an exogenous filtration marker (baseline); proteinuria (baseline and monthly by urine dipstick); serum cystatin C and urine protein-to-creatinine ratio (baseline and every 3 months); urine samples should be obtained prior to infusion or at least 48 hours after the most recent infusion and use laboratory tests that do not use reagent pyrogallol red (may cross react with golodirsen leading to false positive); hypersensitivity reactions during infusion.
Binds to exon 53 of dystrophin pre-messenger RNA (mRNA), resulting in exclusion of this exon during mRNA processing. Exon 53 skipping allows for production of an internally truncated dystrophin protein in patients with genetic mutations that are amenable to exon 53 skipping.
Distribution: Vdss: 0.67 L/kg.
Protein binding: Plasma: 33% to 39%.
Half-life elimination: 3.4 hours.
Excretion: Urine (mostly unchanged).
Altered kidney function: In non-Duchenne muscular dystrophy adults with chronic kidney disease (CKD), AUC increased ~1.2-fold and 1.9-fold in stage 2 CKD and stage 3 CKD, respectively. Cmax increased 1.2-fold in patients with stage 3 CKD.
