Positive Preclinical Proof-of-Concept Results For Liver Cancer Candidate, TXR-311

In September 2016, we announced a collaboration with the Asian Liver Center at Stanford University School of Medicine (the Asian Liver Center). The goal of this collaboration was to identify new drug candidates targeting hepatocellular carcinoma (HCC, the major form of adult liver cancer). Today, we announced a lead candidate, TXR-311, that has shown positive results in cell-based assays. I wanted to share a bit more background on liver cancer and details on why these results are exciting.

HCC is a primary cancer of the liver that tends to occur in patients with…

Seeing the power of AI in drug development

Today we announced our collaboration with Santen, a world leader in the development of innovative ophthalmology treatments. Scientists at twoXAR will use our proprietary computational drug discovery platform to discover, screen and prioritize novel drug candidates with potential application in glaucoma. Santen will then develop and commercialize drug candidates arising from the collaboration. This collaboration is an exciting example of how artificial intelligence-driven approaches can move beyond supporting existing hypotheses and lead the discovery of new drugs. Combining twoXAR’s unique capabilities with Santen’s experience in ophthalmic product development and commercialization…

The AI 100 & Combining Artificial Intelligence with Human Intelligence in Drug Development

We at twoXAR were very honored to be included this week in The AI 100, CBInsight’s list of top private Artificial Intelligence companies. It’s given me a chance to reflect on how we employ AI relative to others in the industry.

 Our focus is on drug development — and being one of the few biopharma companies to be included in the list, we use AI in a unique way. Where others may be using AI as the sole ingredient…

Inspiration from the TEDMED Stage

As with many of my fellow Americans, I have been reflecting about events that have been highlighted in 2016 in the media. Racial strife, gun violence and a polarizing political environment were repeated themes throughout the year. Over dinners and social events, the conversations with friends and family have been morose at times, as many are wondering if society is taking a turn for the worse.

I’m here to tell you that isn’t the case — there is a dedicated group of talented individuals working quietly to make the world a better place.

As a recent speaker at TEDMED 2016, I was fortunate enough to meet dozens of these inspiring pioneers and watch them on stage answering a question…

Consider Your Biases

In the wake of Donald Trump’s victory over Hillary Clinton, pundits and politicians alike have wondered, “how did we not predict this?” Theories range from misrepresentative polling to journalistic bias to confirmation bias, fueled by the echo chambers of social media. These fervent debates about bias in politics had me reflecting on the role that bias plays in science and in R&D. Sampling bias, expectancy bias, publication bias… all hazards of the profession and yet science is held up against other disciplines as relatively bias-free by virtue of its data-centric approach.

Biopharma R&D has rapidly evolved over the last few years — it is more collaborative, demands greater speed to respond to competition, and challenges many notions of “conventional” drug discovery. In my reflections, I was curious whether this rapid evolution was a harbinger of biases not conventionally associated with science — and wanted to understand how we at twoXAR aim to stay aware and ahead of such biases.

Augmenting Drug Discovery with Computer Science

The short-list for the annual Arthur C. Clarke Award was recently announced and it reminded me of a post we did last fall on augmentation vs. automation. Clarke is a British science fiction writer who is famous for being the co-screenplay writer (with Stanley Kubrick) of the 1968 film 2001: A Space Odyssey. He is also known for the so-called Clarke’s Laws, which are three ideas intended to guide consideration of future scientific developments.

  1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
  2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
  3. Any sufficiently advanced technology is indistinguishable from magic.

These laws resonate here at twoXAR where every week we meet with biopharma research executives who tell us — usually right after we say something like, “using our platform you can evaluate tens of thousands of drug candidates and identify their possible MOAs, evaluate chemical similarity, and screen for clinical evidence in minutes” — that’s “impossible” or “magic”!

Mission Possible: Software-driven Drug Discovery

Originally published at Life Science Leader Online.

In the 25-plus years since the modern Internet was launched we have seen virtually every industry evolve by leveraging the connected, global computing infrastructure we can now tap into any time, from anywhere. Today, advanced software programming tools like machine learning, massive data sets and cloud-based compute are making it easier than ever to rapidly launch and globally scale software-driven services without the capital expense that was once required.

The debate about whether or not software will eat drug discovery is not a new one and remains a topic that can raise voices. As a formally educated computer scientist and cofounder of a company focused on software-driven drug discovery, I come to the discussion with my own biases.

There is no shortage of software in today’s biopharma R&D organization. Cloud-based electronic data capture (EDC), laboratory information management systems (LIMS), process automation, and chemical informatics are just a few of the well-established tools that support R&D and have a meaningful impact. While software has become a …

The Power of “Lookup Biology”

Guest post by Marina Sirota, PhD, twoXAR Advisor and Assistant Professor, UCSF Institute for Computational Health Sciences

Earlier this month, Andrew A. Radin and I had the opportunity to attend acommunity outreach meeting at UC Irvine hosted by the NIH Libraries of Cellular Signatures (LINCS) consortium. It was a great and diverse community gathering of drug discovery researchers from academia, biopharma, startups, consulting companies and government funding agencies. For anyone interested in listening to the talks, some of them have been posted on YouTube.

The focus of day one was…

What’s the difference between “software-led” and “using software”?

Ask an automotive engineer to improve passenger safety and they will invent features like seat belts, airbags and anti-lock brakes. Ask a software engineer to improve passenger safety and they will replace the driver with sensors and software.

The power of software-led projects goes beyond…
