Committee Expresses Support
During a subsequent vote among committee members, most expressed support for the technology and its benefits. Sixteen members voted in support, one abstained, and two voted against the benefit-risk profile.
Andrea Richardson, MD, PhD, professor of pathology at Johns Hopkins in Baltimore, said she voted yes because the incremental benefits of avoiding additional surgeries outweigh the small risk of anaphylaxis.
Henry Royal, MD, MIDAC chair and professor of radiology at Washington University School of Medicine in St. Louis, agreed.
“Even though the benefit of this is on average, quite small, the benefit to the woman who has positive margins that’s converted to negative margins because of use of [LUMISIGHT] is really quite great,” he said. “The risk from this procedure is certainly very manageable.”
Harold J. Burstein, MD, PhD, a professor of medicine at Harvard Medical School and oncologist at Dana-Farber Cancer Institute in Boston, voted against the benefit-risk profile. He said the technology merits more research and that he does not believe it was proven the technology reduces the risk of reoperation.
“I think it’s a great technology,” he said. “I would like to see a well-conducted, randomized, phase III study with the endpoint of reoperation,” he said. “That would really prove the usefulness and benefit of the intervention in my mind.”
Chengjie Xiong, PhD, professor of biostatistics at Washington University School of Medicine in St. Louis, chose to abstain from voting because he said there was not enough data.
The FDA will now complete its review of Lumicell’s new drug application for LUMISIGHT and review of its premarket approval application for Lumicell DVS. The FDA review team has 6-10 months to make a decision. As part of the process, the FDA will evaluate clinical data, travel to clinical study sites to conduct inspections, and assemble a final action package for a senior FDA official to make a final decision.
If deemed safe and effective, the FDA will then work with Lumicell on developing and refining prescribing information.
Dr. Ferrer said his team expects to receive FDA approval in the coming weeks and will continue to work collaboratively with the FDA to expedite approval where possible.
The purpose of the MIDAC is to review and evaluate data about the safety and effectiveness of marketed and investigational human drug products for use in diagnostic and therapeutic procedures using radioactive pharmaceuticals and make appropriate recommendations to the FDA Commissioner.
