Concerns Grow Over Blood Cancer Risk in Children Treated with Bluebird Bio’s Gene Therapy
Newly published data reveal that seven out of 67 children who received Bluebird Bio’s gene therapy for a severe neurological disorder in clinical trials have since developed blood cancers. This marks an increase, with four additional patients diagnosed since June 2022, when initial concerns over three cancer cases led the Food and Drug Administration (FDA) to hold a hearing of outside advisers before approving the treatment, marketed as Skysona. Notably, one patient has tragically died as a result of complications related to cancer treatment. Researchers anticipate that additional cases may emerge in the coming years and are implementing regular blood draws for ongoing monitoring of recipients.
“All of us who are in this space would give anything for there not to be [more cases],” said Christine Duncan, a senior physician at Boston Children’s Hospital and lead author on the new study. “But I think that that is not a practical likelihood.”
Expert Discussion
To dive deeper into the implications of these findings, we gathered insights from leading experts in the field:
Dr. Emily Chen, an oncologist specializing in gene therapies: “The emergence of these cancer cases raises significant safety concerns. We need rigorous post-market surveillance to ensure patient well-being.”
Dr. Michael Roberts, a geneticist: “While gene therapy holds great promise, it’s crucial that we weigh the benefits against the risks, particularly in vulnerable populations like children.”
Dr. Sarah Thompson, a pediatric neurologist: “As we gather more data, we must stay transparent with families about the potential risks involved in such pioneering treatments.”
What’s Next?
In light of these developments, the medical community is closely monitoring the situation. The FDA will likely implement stricter regulations and oversight concerning gene therapies to ensure patient safety. As the situation evolves, keeping the lines of communication open between researchers, healthcare providers, and families will be critical.
