I thought it would be intersting to have a thread on Neoleukin Therapeutics, since it is a spin-off from the IPD and Rosetta crunchers have helped in designing de novo proteins.

Unfortunately, this topic starts with bad news: Neoleukin Therapeutics Receives Clinical Hold Letter from U.S. FDA Related to CMC Assay Development for NL-201. This means their phase I trial for the anticancer protein will be delayed at best, canceled at worst. Let's hope it will be the former.

Thanks. It seems to be a measurement problem more than anything.
We need feedback on what is going in in any case.

Let's hope all issues are resolved soon. I'd love to see all that crunching (and folding) lead to actual therapies!

Does anyone know if they are still working on their COVID antiviral?

I don't see anything on their Research Page about a COVID Antiviral.

NL-CVX1

NL-CVX1 is a de novo protein that binds to the spike protein of SARS-CoV-2, the virus that causes COVID-19 and blocks infection of human cells. The design and characterization of NL-CVX1 in under three months underscores the speed and versatility of Neoleukin's de novo protein platform.

In June 2021, in response to the evolving COVID-19 therapeutic landscape, including the widespread availability of effective vaccines, Neoleukin suspended plans to advance this research program into clinical trials.

So it appears that they have suspended it for now, since there are other treatments available.
But I wonder if with the new (nu) variant, they will revive their plans? It could be more effective than the others.

Thanks! Bad news unfortunatelty. June was before the delta variant became dominant in the US, I believe?

Our current vaccines work, but the surge of infections in highly vaccinated regions show they're not enough to reach herd immunity. It's possible we will need more than vaccines to defeat this virus.

Yes, exactly. Also, a lot of people wait until they end up in the hospital to take it seriously. Some don't even get the message then.

They are discontinuing NL-201... From their presentation it seems like they are looking a their COVID drug again, though I'm not sure.

Bad news again for de novo protein design drugs. Icosavax' stock has also plummeted. Their Covid vaccine has been approved but seems less efficacious than the MRNA vaccines.

That's terrible news.

I remember this article on the vaccine in which some South Korean health officials questioned the efficacy of the vaccine without the booster.
http://www.koreabiomed.com/news/articleView.html?idxno=14354
Regardless, the vaccine works but it arrived too late considering many people have already been vaccinated and we have bivalent vaccines available.

It is :( I hope the technology will still prove its worth in future drug design.
