> Pharma’s burned billions chasing this as it’s possibly the biggest market imaginable.
To be clearer, Pharma is chasing a nice long treatment plan, that will require expensive drugs till the end. Pharma does not heal - this is not good for business. So there are criteria around what they are searching for.
I think you are wrong, for several reasons.
From the human perspective, researchers are people, and they do have their incentives. Making a breakthrough, of any kind, is important for them - even if for their career (but many do genuinely care and want to help humanity as a whole).
From marketing and sales perspective, look at what happen to pharma companies capitalization when Ozempic appeared: a relatively small Elly Lily suddenly got bigger then Merck, Novartis, Roche or Johnson & Johnson. You can hardly call it a long treatment plan with expensive drugs "till the end".
Really, there is a lot of bad things going on in healthcare and pharma industry, but the conspiracy theory "they don't want to invent efficient drugs" really makes no sense when you dig deeper.

This is a trope regurgitated by people who don't know any better. It would imply that pharma are deliberately avoiding research directions that would generate cures, or (even worse) discovering cures and putting them in a dark secret safe somewhere.
The reality is that drug development is serendipitous and really hard, and any company seeing even a sniff of a drug that works will throw everything behind making that drug a success. During the early stages of investigation of a promising new agent, the animal data can't predict much, and certainly can't predict whether something is "curative" - this would only be seen during human trials, after which hiding that benefit would be close to impossible. It's just not how it works.
There are plenty of examples of actual (rather than functional) cures being developed and marketed:
1) Previously-untreated DLBCL (a type of blood cancer) can be cured. CHOP chemotherapy cured ~35-40% of cases. The addition of rituximab boosted that to 60-65%. There then followed a long string of failed phase III studies (probably billions spent, cumulatively) trying to beat rituximab + CHOP, and finally in recent years there has been some success. So: multiple attempts across multiple pharma companies, trying to improve on an already impressive cure rate... not much evidence of an anti-cure conspiracy.
2) Hepatitis C - cures were discovered and marketed from ~2014 onwards; now ~95% of cases can be cured with a treatment lasting only a couple of months. So: multiple treatments, from multiple pharma companies, which offer a hugely effective cure for a pretty unpleasant disease.
