revolutionizing drug discovery & delivery

revolutionizing drug discovery & delivery

If you had to guess how long it takes for a drug to go from an idea to your pharmacy, what would you guess? 3 years? 5 years? How about the cost? $30 million? $100 million?

Well, here’s the sobering truth: Ninety percent of all drug possibilities fail. The few that do succeed take an average of ten years to reach the market and cost anywhere from $2.5 billion to $12 billion to get there.

But what if we could generate novel molecules to target any disease, overnight, ready for clinical trials? (This is a topic I will cover at my upcoming Abundance 360 mastermind this January.)

Imagine leveraging machine learning to accomplish with 50 people what the pharmaceutical industry can barely do with an army of 5,000.

Welcome to the future of AI and low-cost, ultra-fast and personalized drug discovery.

Let’s dive in….

GANs & Drugs

Around 2012, computer scientist-turned-biophysicist Alex Zhavoronkov started to notice that artificial intelligence was getting increasingly good at image, voice, and text recognition.

He knew that all three tasks shared a critical commonality. In each, massive datasets were available, making it easy to train up an AI.

But similar datasets were present in pharmacology. So, back in 2014, Zhavoronkov started wondering if he could use these datasets and AI to significantly speed up the drug discovery process.

He’d heard about a new technique in artificial intelligence known as generative adversarial networks (or GANs).

By pitting two neural nets against one another (adversarial), the system can start with minimal instructions and produce novel outcomes (generative). At the time, researchers had been using GANs to do things like design new objects or create one-of-a-kind, fake human faces, but Zhavoronkov wanted to apply them to pharmacology.

He figured GANs would allow researchers to verbally describe drug attributes: “The compound should inhibit protein X at concentration Y with minimal side effects in humans,” and then the AI could construct the molecule from scratch.

To turn his idea into reality, Zhavoronkov set up Insilico Medicine on the campus of Johns Hopkins University in Baltimore, Maryland, and rolled up his sleeves.

“It took us three years of hard work to develop a system that researchers could actually interact with in this way,” Zhavoronkov explains. “But we pulled it off, and this has allowed us to reinvent the drug discovery process.”

Instead of beginning their process in some exotic locale, Insilico’s “drug discovery engine” sifts millions of data samples to determine the signature biological characteristics of specific diseases.

The engine then identifies the most promising treatment targets and—using GANs—generates molecules (that is, baby drugs) perfectly suited for them. “The result is an explosion in potential drug targets and a much more efficient testing process,” says Zhavoronkov. “AI allows us to do with fifty people what a typical drug company does with five thousand.”

The results have turned what was once a decade-long war into a month-long skirmish.

In late 2018, for example, Insilico was generating novel molecules in fewer than forty-six days, and this included not just the initial discovery, but also the synthesis of the drug and its experimental validation in computer simulations.

Right now, they’re using the system to hunt down new drugs for cancer, aging, fibrosis, Parkinson’s, Alzheimer’s, ALS, diabetes, and many others. The first drug to result from this work, a treatment for hair loss, is slated to start Phase I trials by the end of 2020.

They’re also in the early stages of using AI to predict the outcomes of clinical trials in advance of the trial. If successful, this technique will enable researchers to strip a bundle of time and money out of the traditional testing process.

Protein Folding

Beyond inventing new drugs, AI is also being used by other scientists to identify new drug targets—that is, the place to which a drug binds in the body and another key part of the drug discovery process.

Between 1980 and 2006, despite an annual investment of $30 billion, researchers only managed to find about five new drug targets a year.

The trouble is complexity. Most potential drug targets are proteins, and a protein’s structure—meaning the way a 2D sequence of amino acids folds into a 3D protein—determines its function.

But a protein with merely a hundred amino acids (a rather small protein) can produce a googol-cubed worth of potential shapes—that’s a one followed by three hundred zeroes. This is also why protein-folding has long been considered an intractably hard problem for even the most powerful of supercomputers.

Back in 1994, to monitor supercomputers’ progress in protein-folding, a biannual competition was created. Until 2018, success was fairly rare.

But then the creators of DeepMind turned their neural networks loose on the problem. They created an AI that mines enormous datasets to determine the most likely distance between a protein’s base pairs and the angles of their chemical bonds—aka, the basics of protein-folding. They called it AlphaFold.

On its first foray into the competition, contestant AIs were given forty-three protein-folding problems to solve. AlphaFold got twenty-five right. The second-place team managed a meager three.

Drug Delivery

Another theatre of war for improved drugs is the realm of drug delivery.

Even here, converging exponential technologies are paving the way for massive implications in both human health and industry shifts.

One key contender is CRISPR, the fast-advancing gene-editing technology that stands to revolutionize synthetic biology and treatment of genetically linked diseases.

And researchers have now demonstrated how this tool can be applied to create materials that shape-shift on command. Think: materials that dissolve instantaneously when faced with a programmed stimulus, releasing a specified drug at a highly targeted location.

Yet another potential boon for targeted drug delivery is nanotechnology, whereby medical nanorobots have now been used to fight incidences of cancer. In a recent review of medical micro- and nanorobotics, lead authors (from the University of Texas at Austin and University of California, San Diego) found numerous successful tests of in vivo operation of medical micro- and nanorobots.

Drugs From The Future

Inefficient, slow-to-innovate, and risk-averse industries will all be disrupted in the years ahead. Big Pharma is an area worth watching right now, no matter your industry.

Converging technologies will soon enable extraordinary strides in longevity and disease prevention, with companies like Insilico leading the charge.

Riding the convergence of massive datasets, skyrocketing computational power, quantum computing, cognitive surplus capabilities and remarkable innovations in AI, we are not far from a world in which personalized drugs, delivered directly to specified targets, will graduate from science fiction to the standard of care.

Rejuvenational biotechnology will be commercially available sooner than you think. When I asked Alex for his own projection, he set the timeline at “maybe 20 years — that’s a reasonable horizon for tangible rejuvenational biotechnology.”

How might you use an extra 20 or more healthy years in your life? What impact would you be able to make?

Some interesting observations, but also some repeated and even exaggerated myths about the costs and difficulties of developing treatments, which are then doubled down in many of the comments.? Sure, life is difficult - show me an industry where it is not.?? Truth is the pharma industry is a dinosaur that is slowly evolving but way too slowly and it is all to easy to blame regulators, who are pilloried at the same time for being too close to industry.? Regulators are striving to reduce lead times through all sorts of initiatives while maintaining patient safety. AI does indeed have great potential, not only in development but also in evidence generation, but alongside all of this the pharma industry has not really woken up to the potential of involving patients in all aspects of medicines development from benchtop to bedside.? The auto industry long ago recognised that spending huge sums on developing cars that nobody wanted to buy was not a good business model.? Ask your customers what they need - just a thought!

Generating the candidate molecules is not where the delay or pharmaceutical development failure happens, it's the protracted clinical trials and "cautious regulator" drug approval process. Initiatives like Quality by Design have struggled to cut this knot. I think the last estimate by diMasi was that drug development costs were 2.6 Bn $ (2013 cost) per success, allowing for finance costs and a pro rata share of failed molecule trials. Those costs were trending up by 8% pa. Anything to help tackle that is welcome, but the clinical trial/proof of safety and effectiveness is the big hurdle and cost constraint.

This was being done 25 years ago and led nowhere. The deep reason is that drugs work within a lock and key mechanism. Any new compound that doesn’t adhere to this restriction is useless.
