DES hasn't been manufactured for as long as I've been alive. Also, Bristol-Meyers-Squibb manufactured it, too, as well as other companies.
TBF, from a strictly legal perspective this makes these cases pretty tough to prove.We're talking a drug taken by women 30 years ago that increases the risk of esoteric cancers (it pretty much did, there's not much debate on that front as these tumors are bizarre). The problem is it's hard to tell what brand, if it was used.
Expect the usual mass tort suit and a few settlements for the more seriously aggrieved for the sake of common decency/PR. This isn't thalidomide. It's an increased likelihood of cancer, not lifelong handicaps aside from gender dysphoria, which I doubt anyone will sue over. From a legal perspective a single injury is always cheaper than a chronic disabling one or death.
Again, while from a human perspective, a sad footnote in pharmaceutical history, from the financial perspective, noise.
