The idea of using CRISPR/Cas to detect tumor-specific mutations that aren't necessarily oncogenic and then kill the cell is not a new one [0, 1, 2]. However, previous studies used Cas9, which just damages the DNA at the target site; this uses Cas12a2, which is far more destructive because it shreds the chromatin in the cell once activated by detecting the target sequence.
As with any cancer treatment, it's likely the tumor will evolve resistance. My guess is that cells will find ways to reject the lipid nanoparticles used to deliver the CRISPR/Cas mRNA and associated guide sequence(s), either via modifications to the cell surface (preventing LNP uptake) or via changes to endosomal/lysosomal pathways (causing the mRNA payload to get degraded before it has a chance to be translated into protein).
But cancer isn't an organism. Cancer cells in any specific individual may evolve that way, but "human cancers" as a group will not. (The only way they could is by evolving human DNA, but "survival of the fittest" pushes the opposite direction for that.)

There are some ideas about making it triggerable. So first you load the cells with a protein that is ready to start shredding but is inactive. Then you trigger it with a second compound.

CRISPR is an extremely overhyped approach which found a marketing engine via popular science. There is 1 FDA approved CRISPR therapy as compared to 7 for AAV and 7 for Lentivirus.
Counting all viral vector therapies that have been approved, we’re sitting at 19 approved therapies versus 1 for CRISPR.
I think CRISPR ideas in a lab are just an easy way into the mainstream press, but viral vector delivery is the real future. It just didn’t get the same news cycle, for whatever reason.

You're correct about CRISPR Cas9. The off-target affects are difficult to manage.
The paper describes Cas12a2. This is a different mechanism with discovery origins in - of all things - agriculture. It does not attempt in any way to reprogram cells. It uses a guide protein to locate a specific mutation with exacting precision and, when it activates, unleashes total destruction of the cell.
The implications of Cas12a2 on undruggable conditions that exhibit known driver mutation profiles is profound.
Source: I have personally funded novel research based on Cas12a2 for an undruggable condition I have. I have personally seen my condition "cured" in vitro using this technology and it left all of my WT cells unharmed. Some of the researchers I've funded are co-authors in the paper linked. I am a layperson in this field (I'm a SWE, not in biotech), but I am happy to answer questions.

So what does this change exactly? Humans defined it as "undruggable conditions". You can reason this is an improvement, but I still see it in failure-territory. If it were to work, gene therapy would be an accurate - and affordable - technique. Which it is not right now.

There are two major problems, delivery is one of them. Collateral damage of mass cell destruction leading to systemic inflammation is the other.
The approach I'm reviewing now uses lipid nanoparticles (LNPs) for delivery. It isn't great for targeting my bone marrow condition but its workable. The team hasn't optimized it at all, either. There are also viral delivery mechanisms that I haven't studied yet.
The collateral damage problem is the backpressure on the delivery problem. If you get really good at delivery, you can destroy A LOT of cells very quickly. The human body (usually) responds to these events by releasing a lot of pro-inflammatory cytokines. This can lead to cytokine storms or worse.
As you "get good" at killing the target cells, the net effect can turn bad. It will probably be a balancing act.

Lipid nanoparticles are quite old as-is. How do you target cells specifically?
> If you get really good at delivery, you can destroy A LOT of cells very quickly.
You can destroy cells quickly. Ok. So the question is: how do you detect specifically only cancer cells via lipid nanoparticles? That was already a problem years ago with Herceptin. The rationale that is always used is that "we need to do something" for certain aggressive cancers. It has never been a super-effective technique, despite all the promo of how monoclonal antibodies are so accurate.
> As you "get good" at killing the target cells, the net effect can turn bad. It will probably be a balancing act.
That's already the status quo in the whole cancer field. I don't think that more than sloppy accuracy is acceptable for any gene therapy - and the off-target cleaving of CRISPR has always been the number #1 problem here.

CRIPSR was a game-changer for genetics research. A lot of gene knockout studies use CRISPR. However, it was always weirdly overhyped for clinical use from the beginning and this was obvious to anyone with a genetics background.
The public in general doesn't have a good understanding of basic genetics and I blame high school science curriculums for not covering it well enough. Too much time is wasted on Mendelian genetics without covering the Central Dogma.
You basically cannot "edit" your somatic DNA in a meaningful wholesale way since every single cell in your body has a copy of the DNA, and it's a foolish endeavor. What you can conceivably edit to good effect is your germline DNA, stem cell DNA, or modify mRNA expression (e.g. retinoids; yes putting retinol/adapalene cream on your face is "gene therapy"), or introduce foreign mRNA for your translation machinery to co-opt (e.g. mRNA vaccines).
projektfu 6 minutes ago [-]
I disagree that it's "gene therapy" to affect the natural regulation of mRNA production. If that were true then the term "gene therapy" loses its meaning, as just about everything changes the expression of mRNA. You can probably do so somewhere just by thinking really hard about it.
Expressing mRNA that doesn't exist in the genome, that would be gene therapy. Or just a virus.
This approach can work for some genetic diseases such as blindness based on some cells in the retina or partial blindness. For others this is not really a cure. If you want to cure people with progeria, does curing 20% of the cells really help? Perhaps 100% is not necessary, but it would seem strange to cure only some cells but not others. You'd have a mosaic of cells where some would work and others don't. Cells interact; timing also plays a role in development. I don't really see that aiming for anything but a very high number of cells cured, can work.

CRISPR is foremost a research tool. Calling it "extremely overhyped" without restricting it medical treatment seems disingenuous.
The CRISPR-Cas9 gene-editing tool was developed in 2012, so I don't find it surprising that merely 14 years later, there's only one approved treatment. From discovery to approval, drug development often takes 10-15 years, and often much longer for novel techniques. So I'd say it too early to call it overhyped for treatments.
Finally, I think we'll see a lot of treatments that don't use CRISPR-Cas9, but related gene editing techniques, but it'll take another 10 to 20 years.
Take a look at https://en.wikipedia.org/wiki/MRNA_vaccine#History for how long another novel technique has been in development before it became really widespread with the mrna-based covid-19 vaccines.
