Scientists are using the same AI foundations to make drug discovery faster, safer and more effective.

Generative artificial intelligence may be having its banner moment, but the technology existed long before ChatGPT and DALL-E. It began in 2014 with a paper by Ian Goodfellow and several other researchers entitled “Generative Adversarial Networks” (GANs). Goodfellow is a computer scientist who worked for Google Brain and Apple and is currently with DeepMind. Today, his paper has been cited more than 55,000 times and underpins several AI tools.

Nearly a decade ago, Goodfellow uncovered a breakthrough: by using technology to draw on large amounts of data, AI tools can generate “synthetic” data under the right conditions. Over time, with constant training and feedback, the system learns to provide synthetic data closely aligned with the desired output. Today, these synthetic data might include smart contract code, fraud detection algorithms, and of course, hyperrealistic avatars with your face in the metaverse.

Generative AI not only solves challenges like coding and risk management but also drives powerful biotech innovations. Despite advances in manufacturing and discovery, it still takes 10-15 years and costs millions of dollars to bring a drug from discovery to market. And instead of declining with technological advances, the cost to bring a drug to market is only increasing.

AI can optimize speed and efficiency in drug discovery by streamlining new targets, designing new drugs, and even determining the likelihood of clinical trial success.

Generative AI enters the chemistry world

In 2016, Dr Alex Zhavoronkov, founder of drug discovery unicorn Insilico Medicine, made waves in the chemistry world by presenting generative AI technology at conferences from London to San Francisco. His research findings seemed farfetched to some but transformative to others–GANs, combined with reinforcement learning, could generate novel molecules for treating diseases.

Seven years ago, many still found AI a sci-fi, futuristic concept. Zhavoronkov brought examples of the technology’s ability to make something new to change people’s minds. He added petals to photographed flowers and generated unique faces to explain how AI can create new molecules. The chemists were skeptical, but Zhavoronkov was undeterred. AI was going to transform our health experiences; it just needed time.

Insilico eventually showed that its AI could find new disease targets. Using generative AI technology to produce and evaluate candidates and drug targets, their platform designed new molecules that could be synthesized, tested and developed into potential treatments.

WuXi AppTec joined Insilico to develop its first generative AI-produced molecules and later invested in the company for further acceleration. Their first drug targets may surprise you: rare disease treatments. Because these diseases are so uncommon, scientists know very little about their chemical structure. AI filled in the gaps to design potential candidates where no structure was available.

They targeted the JAK3 isoform, a DNA sequence related to rheumatoid arthritis and psoriasis. The system generated 300,000 molecules and narrowed the selection to 100 promising targets. Humans joined the process here, with medical chemists choosing the best candidate for further development. The results were published in 2018 in Molecular Pharmaceutics with a clear promise: generative AI was here to disrupt the drug discovery space.

When will AI reach our pharmacies?

Insilico secured patents on its AI technology, but it also received patents for its work on biological aging biomarkers. The company strives to leverage AI to discover powerful anti-aging treatments. While we’re several years from these reaching our medicine cabinet shelves, Insilico is also looking closely at how we age, including measuring our biological age. Aging clocks provide researchers with valuable insights into individual aging processes.

In 2020, Insilico Medicine’s generative chemistry work launched as Chemistry42. The platform uses deep learning and reinforcement learning to generate chemical structures for treating predefined medical targets. Chemistry42 identified a completely new and potentially first-of-its-kind molecule, PandaOmics, for treating fibrosis. The Insilico team designed and synthesized 80 molecules, with one small molecule showing outstanding promise for treating idiopathic pulmonary fibrosis (IPF), a rare and devastating progressive lung disease.

The company had broken new ground by uniting deep learning and chemistry. Major pharmaceutical companies noticed, too, with Pfizer, Arvinas, Fosun Pharma, and Sanofi establishing partnerships with Insilico.

By February 2022, Insilico crossed another threshold by bringing its IPF drug to Phase 1 clinical trials in under 30 months. In January 2023, those Phase 1 trials announced positive topline results, and in February 2023, the IPF drug received Orphan Drug Designation from the FDA. It’s time for Phase 2 clinical trials, where actual IPF patients will enter clinical trials and test the potentially life-changing treatment option.

Next up for AI-generated drugs? COVID-19. Insilico’s oral treatment, ISM3312, will soon enter clinical trials in China. The drug offers protection against mutations and poor outcomes for COVID patients. The world desperately needs rapid solutions to emergent diseases.

Generative AI transcends creative images and in-depth coding. It will change how physicians treat diseases and save countless lives. There’s plenty of room for blockchain too–drug discovery scientists can use DLT to securely exchange clinical research data.

My advice for the crypto community? Join the movement. Your determination brought crypto, blockchain and stablecoins to the mainstream. You can envision a future that other people can’t, and the longevity field needs your unique perspective to help bring this next generation of tech to the fore. Test AI tools in your workspace, read up on AI tokens and monitor medical news for future discoveries. We live in a unique time for technological progress, and it’s our responsibility to support its life-changing outcomes. Merging cutting-edge technology with traditional research and discovery is what will bring all of these life-changing inventions to more people.

Today, in the Calculated Risk Real Estate Newsletter: Part 1: Current State of the Housing Market; Overview for mid-March 2024

A brief excerpt:
This 2-part overview for mid-March provides a snapshot of the current housing market.

I always like to start with inventory, since inventory usually tells the tale!
...
Here is a graph of new listing from Realtor.com’s February 2024 Monthly Housing Market Trends Report showing new listings were up 11.3% year-over-year in February. This is still well below pre-pandemic levels. From Realtor.com:

However, providing a boost to overall inventory, sellers turned out in higher numbers this February as newly listed homes were 11.3% above last year’s levels. This marked the fourth month of increasing listing activity after a 17-month streak of decline.
Note the seasonality for new listings. December and January are seasonally the weakest months of the year for new listings, followed by February and November. New listings will be up year-over-year in 2024, but we will have to wait for the March and April data to see how close new listings are to normal levels.

There are always people that need to sell due to the so-called 3 D’s: Death, Divorce, and Disease. Also, in certain times, some homeowners will need to sell due to unemployment or excessive debt (neither is much of an issue right now).

And there are homeowners who want to sell for a number of reasons: upsizing (more babies), downsizing, moving for a new job, or moving to a nicer home or location (move-up buyers). It is some of the “want to sell” group that has been locked in with the golden handcuffs over the last couple of years, since it is financially difficult to move when your current mortgage rate is around 3%, and your new mortgage rate will be in the 6 1/2% to 7% range.

But time is a factor for this “want to sell” group, and eventually some of them will take the plunge. That is probably why we are seeing more new listings now.

Pharma industry reputation remains steady at a ‘new normal’ after Covid, Harris Poll finds

The pharma industry is hanging on to reputation gains notched during the Covid-19 pandemic. Positive perception of the pharma industry is steady at 45% of US respondents in 2023, according to the latest Harris Poll data. That’s exactly the same as the previous year.

Pharma’s highest point was in February 2021 — as Covid vaccines began to roll out — with a 62% positive US perception, and helping the industry land at an average 55% positive sentiment at the end of the year in Harris’ 2021 annual assessment of industries. The pharma industry’s reputation hit its most recent low at 32% in 2019, but it had hovered around 30% for more than a decade prior.

Rob Jekielek

“Pharma has sustained a lot of the gains, now basically one and half times higher than pre-Covid,” said Harris Poll managing director Rob Jekielek. “There is a question mark around how sustained it will be, but right now it feels like a new normal.”

The Harris survey spans 11 global markets and covers 13 industries. Pharma perception is even better abroad, with an average 58% of respondents notching favorable sentiments in 2023, just a slight slip from 60% in each of the two previous years.

Pharma’s solid global reputation puts it in the middle of the pack among international industries, ranking higher than government at 37% positive, insurance at 48%, financial services at 51% and health insurance at 52%. Pharma ranks just behind automotive (62%), manufacturing (63%) and consumer products (63%), although it lags behind leading industries like tech at 75% positive in the first spot, followed by grocery at 67%.

The bright spotlight on the pharma industry during Covid vaccine and drug development boosted its reputation, but Jekielek said there’s maybe an argument to be made that pharma is continuing to develop innovative drugs outside that spotlight.

“When you look at pharma reputation during Covid, you have clear sense of a very dynamic industry working very quickly and getting therapies and products to market. If you’re looking at things happening now, you could argue that pharma still probably doesn’t get enough credit for its advances, for example, in oncology treatments,” he said.

Today, in the Calculated Risk Real Estate Newsletter: Q4 Update: Delinquencies, Foreclosures and REO

A brief excerpt:
I’ve argued repeatedly that we would NOT see a surge in foreclosures that would significantly impact house prices (as happened following the housing bubble). The two key reasons are mortgage lending has been solid, and most homeowners have substantial equity in their homes..
...
And on mortgage rates, here is some data from the FHFA’s National Mortgage Database showing the distribution of interest rates on closed-end, fixed-rate 1-4 family mortgages outstanding at the end of each quarter since Q1 2013 through Q3 2023 (Q4 2023 data will be released in a two weeks).

This shows the surge in the percent of loans under 3%, and also under 4%, starting in early 2020 as mortgage rates declined sharply during the pandemic. Currently 22.6% of loans are under 3%, 59.4% are under 4%, and 78.7% are under 5%.

With substantial equity, and low mortgage rates (mostly at a fixed rates), few homeowners will have financial difficulties.
