Current drug development process suffers from diversity bottlenecks.

The Lack Of Human Diversity

There are over 7 billion people in the world, and they respond differently to different drugs because they have different genetic compositions. However, only up to 3000 people are tested during clinical trials. As a result, most drugs only work on 10% - 50% of the population, and we don't know which 10% - 50%.

Clinical trials lack human diversity both in the sense that women and ethnical minorities are underrepresented, and that even if everyone is proportionally represented, the absolute number of people in clinical trials is simply too small to capture the genetic diversity of the entire population.

The Lack Of Therapeutic Diversity

On the other hand, the number of drugs that can be given to a patient starts out as infinity. This number reduces with each step along the way to get FDA approval.

Today, it is impossible to test large numbers of drugs across large numbers of people, to find which ones are the best treatment for an individual patient.

Coral Genomics' Product & Vision

Coral Genomics has developed its own novel genetic sequencing techniques to solve the diversity bottleneck problem. Their new techniques make it possible to test how cells from different patients respond to different drugs in a timely and cost-effective way.

They have already built one of the world's largest databases functionally associating genetic variations to drug response and clinical outcomes.

In terms of product, Coral Genomics works with healthcare systems to provide end-to-end precision medicine support from next-generation sequencing to patient/provider facing healthcare reports. Fueled by their large diverse dataset, Coral Genomics' predictions have higher accuracy rates across age, gender, and race, and are more affordable & higher margin than any competitors.

Coral Genomics envisions a future where people's genetic information is in their electronic health records, and treatment for every disease is guided by predictions that harness the genetic diversity of the entire population.

Founding Story

The motivation for building Coral Genomics originated when Atray's family member Inflammatory Bowel Disease (IBD). For IBD patients, there are multiple drugs and treatments, many of which have intense side effects. For a patient, there is no way of knowing if a drug will work for them without actually trying it. For 20% to 40% of the patients, no drugs work and they have to go through surgery in the end.

Atray has witnessed firsthand what it was like to go through this process, where his family member tried a drug that only works for 50% of patients, waited for 6 months, and if the drug was not working restart this cycle all over again with another drug. As an engineer with a background in biology, he thought there must be a better way.

Later Atray did his PhD in medical engineering at MIT, and did extensive research at the Broad Institute. He worked side by side with the inventors of CRISPR, and invented Perturb-Seq, a technique that combined single cell sequencing with CRISPR to understand how gene editing affects cell biology. Perturb-Seq is currently widely used to assist with drug development, and Atray decided to start Coral Genomics to leverage the same principles behind that technology to solve precision medicine for people like his family member.
