Eladocagene exuparvovec, sold under the brand name Upstaza among others, is a gene therapy product for the treatment of aromatic L‑amino acid decarboxylase (AADC) deficiency. It infuses the gene encoding for the human aromatic L-amino acid decarboxylase enzyme into the putamen region of the brain. The subsequent expression of aromatic L-amino acid decarboxylase results in dopamine production and, as a result, development of motor function in people with aromatic L-amino acid decarboxylase deficiency. Eladocagene exuparvovec is an adeno-associated virus vector-based gene therapy.
The most common side effects include initial insomnia, irritability and dyskinesia. The most common side effects of eladocagene exuparvovec (Kebilidi) include dyskinesia (involuntary muscle movements), fever, low blood pressure, anemia (low red blood cell count), increased saliva production, insomnia, low levels of potassium, phosphate, and/or magnesium, and procedural complications such as respiratory and cardiac arrest.
Eladocagene exuparvovec was approved for medical use in the European Union in July 2022, and in the United States in November 2024.{{cite press release | title=FDA Approves First Gene Therapy for Treatment of Aromatic L-amino Acid Decarboxylase Deficiency | website=U.S. Food and Drug Administration (FDA) | date=14 November 2024 | url=https://www.fda.gov/news-events/press-announcements/fda-approves-first-gene-therapy-treatment-aromatic-l-amino-acid-decarboxylase-deficiency | archive-url=https://web.archive.org/web/20241114190854/https://www.fda.gov/news-events/press-announcements/fda-approves-first-gene-therapy-treatment-aromatic-l-amino-acid-decarboxylase-deficiency | url-status=dead | archive-date=14 November 2024 | access-date=17 November 2024}} {{PD-notice}}{{cite web |date=2024-11-13 |title=PTC Therapeutics Announces FDA Approval of AADC Deficiency Gene Therapy |url=https://ir.ptcbio.com/news-releases/news-release-details/ptc-therapeutics-announces-fda-approval-aadc-deficiency-gene |access-date=2024-11-21 |website=PTC Therapeutics, Inc.}}
Medical uses
Eladocagene exuparvovec is indicated for the treatment of aromatic L-amino acid decarboxylase (AADC) deficiency.
Aromatic L-amino acid decarboxylase deficiency is a rare genetic disorder that affects the production of some neurotransmitters, which are chemical messengers that allow cells in the body's nervous system to communicate with each other. Affected individuals may experience symptoms such as delays in gross motor function (head control, sitting, standing, and walking), hypotonia (weak muscle tone), and developmental and cognitive delays.
Contraindications
History
The safety and effectiveness of eladocagene exuparvovec were demonstrated in an open-label, single-arm clinical study in 13 children with confirmed diagnosis of aromatic L-amino acid decarboxylase deficiency. At the start of the study, all participants had no gross motor function (the most severe presentation of aromatic L-amino acid decarboxylase deficiency) and decreased aromatic L-amino acid decarboxylase activity in the plasma. Participants treated with eladocagene exuparvovec were compared to untreated participants (natural history). Motor milestone assessments were completed for 12 of the 13 participants at week 48 after receiving the treatment. The efficacy of eladocagene exuparvovec was demonstrated based on gross motor function improvement in 8 of 12 treated participants, which has not been reported in untreated participants with the severe presentation of aromatic L-amino acid decarboxylase deficiency.
