My wife’s company developed a multiple myeloma immunotherapy that is for people that have had previous treatments of other drugs but then go into remission.

It works so well that their efficacy reports have caveats like “not enough patients that were treated have died yet” to provide meaningful statistics.

The drug was initially developed in china. They presented results at a conference in the USA but no one believed them other than a skeptical Pfizer who sent a big team to china to confirm the data. Pfizer soon invested billions into the company and drug to bring it to market.

The drug’s sales are on track to be $1 billion this year but the stock is heavily depressed because of the china connection.
