Pune:Eleven-month-old baby, Vedika, who was suffering from Spinal Muscular Atrophy (SMA) and was administered Rs 16 crore injection - Zolgensma, a gene therapy medication to treat SMA, passed away on Sunday evening. She was administered with the injection in June.
Zolgensma, a single-dose intravenous injection gene therapy in which the defective SMN1 gene is replaced through an adenoviral vector, is currently not available in India and has to be imported from the United States.
The disease progressively destroys nerve cells in the brain stem and spinal cord that control speaking, walking, breathing, and swallowing and is caused due to a defect in the SMN1 gene.
The affected children develop muscle weakness involving upper and lower limbs initially, but over time develop breathing difficulty and swallowing difficulty.
