Reply to comment by mli in ‘Near-limitless CRISPR therapies’: This drug delivery breakthrough helps gene editing technology infiltrate cells by Ezekiel_W
That's exactly what I was wondering. I've been hearing about Crispr for I think more than 10 years, but I am yet to hear about Crispr being actually used as a treatment. Why is that ?

We need those 10 or so years for more research and development. Humans have had CRISPR used on them many times already, but it's still early days for human trials. Most of the good stuff with CRISPR probably won't start appearing until the late 2020s.

It’s probably just that medical technologies take a long time to be approved.

This has always been true. Increasingly we are able to use biological modeling in virtual space to simulate trials as we did with the COVID-19 vaccine. In that instance bringing the development time down from 5 to 10 years to one year.
Remember exponential not linear

TLDR: drugs in a nutshell.
Its because we don't know what effects a drug will have until we actually inject it. You have to realize that our entire body is a diffusion prone liquid chamber of a billion moving parts but we need to deliver soluble drugs to a very specific target number of cogs. That's physically impossible btw.
So we end up having unknown side effects, and every drug has them. We just have to be persistent and select the ones that are effective at curing yet tolerable enough, but this process can take upwards to a decade in clinical trials.
In practice this means we have a decade long backlog of drugs that we think are promising but haven't had the time or resources to check. We'll get to testing CRISPR in maybe a few more years.
One more thing, as a scientist who has used CRISPR systems in cell cultures, its not that 'robust' yet. If I had to choose between successful CRISPR and fliiping a coin in a game of russian roulette, I'd still take the coin lol.

But... we are already testing CRISPR. I think the first human trials were 5 or 6 years ago.

It takes about a generation to go from technological breakthrough to large scale deployment of these types of innovation.
There are a lot of nuts-and-bolts R&D, medical safety testing, manufacturing, supply, and logistics issues to consider when looking at how new discoveries will broadly impact society.
So, from the initial Crispr breakthrough to actually seeing the effects of this revolutionary tech, you are looking at 15 - 25 years for some of the most important innovations to be noticeable for those of us outside the laboratory.

Blame the FDA and... realize biology is a fucking mess. Specially with novel therapeutic vectors. We've rushed before in clinical trials that have maimed and killed humans.
I remember one of those, guess what happened? The field was frozen for almost 10 years. Nobody wanted to put money or political face on and have the same thing happen again.
So it takes years and years of mountains of paperwork and money and tests and more paperwork to prove safety first and then efficacy. I'd rather do most of these by compassionate use, but... I'm not in charge.

Big Pharma

I don't think you know about big pharma. They want these things by yesterday, because of money, you know? Always have but are heavily slowed down by the FDA's guidelines demanding all evidence in the world that this won't ever ever backfire in humans. This means more time and money spent performing safety preclinical and clinical trials and endless mountains of paperwork and years of back and forth with them.
