FDA Confident Zolgensma Should Stay on Market
FDA says it is confident that AveXis’ Zlogensma, a gene therapy product intended to treat children less than two years old with spinal muscular atrophy with bi-allelic mutations in the survival motor neuron 1 gene, that was approved by the agency 5/24, should remain on the market despite data manipulation concerns raised by the manufacturer after approval. An agency statement says FDA was informed 6/28 about a data manipulation issue that affects the accuracy of certain data from product testing performed in animals submitted in the BLA reviewed by FDA.
The statement says the agency is carefully assessing the situation and “remains confident that Zolgensma should remain on the market. Out of the large amount of submitted information reviewed by the agency, our concerns at this time are limited to only a small portion of the product testing data that was included in the marketing application. This product testing data was used by the manufacturer to support the development of its production process for the product. These data do not change the agency’s positive assessment of the information from the human clinical trials that were conducted as part of the development program.”
FDA says the totality of the evidence demonstrating the product’s effectiveness and its safety profile continues to provide compelling evidence supporting an overall favorable benefit-risk profile.
The statement acknowledges that the manufacturer became aware of the data manipulation before FDA approved the product and did not inform the agency until after the approval. It says the agency will act against the company, if appropriate, and could impose civil or criminal penalties.
