Blocking Cancer’s Deadly Spread

When cancer cells migrate from the primary tumor, they can seed secondary tumors in distant organs. Once metastasis happens, it’s difficult to control. Our mission at Volastra is to block that spread.

Our scientific founders discovered a key biological pathway that drives metastasis: A mechanism known as chromosomal instability, or CIN. When cells divide, their chromosomes usually separate in an orderly fashion. In CIN-High cancers, this process is highly error prone.

High levels of CIN drive cancer metastasis and treatment resistance, as well as increased risk of disease recurrence and death.

We are working to turn those groundbreaking insights into life-saving therapies.

Chromosomal instability is a driver of cancer metastasis, but how? Learn about one pathway through which cancer cells spread.

What drives cancer metastasis?

Custom Controls

>350,000 people in
the U.S. get metastatic cancer yearly

Metastatic tumors account for 90% of cancer deaths

70% don’t respond to targeted or immunotherapies

A Multi-pronged Attack

Blocking metastasis is a challenge. We’re coming at it with state-of-the-art technology incorporating both computational and experimental approaches.

We are building a technology combining artificial intelligence, bioinformatics and proprietary imaging techniques to identify which cancers have high levels of chromosomal instability, or CIN – and are therefore more likely to metastasize.

We’re also evaluating our unique therapeutic approaches in metastatic tumor organoids, which lets us test our ideas far more quickly than we could with animal models alone.

Applying this proprietary technology we will identify targets quicker, select the appropriate patients for therapy more effectively and ultimately improve patient outcomes.

Our Founders

Bakhoum, M.D., Ph.D.
Cantley, Ph.D.

In 2016, Samuel Bakhoum joined the lab of world-renowned cancer biologist Lewis Cantley with an idea: to study chromosome behavior and how it might drive cancer metastasis.

Elemento, Ph.D.

They recruited their colleague Olivier Elemento, whose lab combines big data analytics, including artificial intelligence and mathematical modeling, with experimentation to develop entirely new ways to help prevent, diagnose, understand, treat and ultimately cure cancer. Together they saw a path toward targeting a root cause of cancer metastasis.


Just a few years later, in January 2018, they published a study in Nature showing for the first time how CIN allows cancerous cells to evade the immune system and spread.


With this groundbreaking
finding, Volastra was born.
