Okay, I'm calling it like Babe Ruth pointing to the center field fence at the 1932 World Series: Therapies using a targeting protein attached to a radioisotope are about to explode.
Lutetium dotatate received US Food and Drug Administration approval in January 2018. The intervening months have seen its use skyrocket. "Lutathera...has been very commercially successful so far. GlobalData forecasts the drug to grow further, reaching $699 million in peak sales." Novartis clearly agreed with the prediction that the drug will continue to perform well, and externally available data seem to indicate that they were correct (pandemic complications notwithstanding).
This last week saw the approval of lutetium vipivotide tetraxetan for use in castrate-resistant metastatic prostate cancer. The drug was already under investigation in a large clinical trial in patients who have not had previous treatment with cytotoxic chemotherapy. The current indication is for patients at a later line of treatment, so use would likely be expanded if the ongoing trial were successful.
The ability to treat other cancers in a similar fashion is limited by our ability to generate molecules that target cancer cells but not their normal cells of origin. Yes, and all we need globally is a never-ending free energy source, I know. Much easier said than done. But it certainly seems like we are on the verge of a great deal of progress in that direction.
Unfortunately, the United States has long lagged in production of radioisotopes, leaving us in a poor position to take full advantage of this technological growth, one that was made more noticeable by the pandemic. I hope that leaders in the field are taking notice of the trend and making plans accordingly.
Are you using targeted radioisotopes in your health center? What do you predict for their future?
