Oncology Drug Discovery is complex.

Your research model needs to reflect that complexity too.

"The history of cancer research has been a history of curing cancer in the mouse," Dr. Klausner, Director of the National Cancer Institute. "We have cured cancer for decades, and it simply didn't work in humans." - Los Angeles Times 1998

Today, conventional models and systems for translating oncology drugs into clinical trials have not significantly impacted the failure rate seen in the pharmaceutical industry, with greater than 90% of novel therapeutics failing to reach the market - 50% of those due to lack of efficacy in clinical studies.

This trend has continued… until now.

Vivan Therapeutics’ avatars will improve your potential to succeed in the clinic by helping you make better decisions every step of the way.

Our in vivo avatars allow us to do what no other model can. We create a virtual biological twin of each patient by replicating polygenic tumor complexity (engineering up to 20 mutations, not just one mutation) into a living, biological system.

High throughput screening in a disease-relevant, in vivo model

• Test thousands of drugs and combination of drugs in over 500,000 avatars of each patient model

85% of the time, patients require a minimum combination of 2 or 3 drugs to combat their cancer

• Discover novel combinations, develop a biomarker strategy, and enable the repurposing of existing drugs

Developed at the Icahn School of Medicine at Mount Sinai, New York and commercialised by Vivan Therapeutics.

We help direct the treatment of cancer patients, enabling the rapid identification of combination therapies to treat polygenic diseases, as well as providing our Biopharma partners with patient-relevant models to test novel therapies and combinations.

How it works

We supply avatar models from our “flybrary” of patient models, and/or create models to your specifications, you supply your compounds. Our project team works with you to define the requirements of your study through to project execution and final report. Studies using existing avatars can be completed in less than a month.

As patients are recruited, tumor tissue is acquired

Each patient’s entire exome is analysed to capture their tumor’s network

Up to 20 genetic alterations from a patient’s tumour network are engineered into a fruit fly avatar

Up to 2,000 FDA approved drugs plus novel compounds and combinations are screened in half a million avatars

Our technology was developed by the Icahn School of Medicine at Mount Sinai over years of clinical research and is being used to treat patients today. They have discovered that real-world patient tumours are made resistant to single-drug treatments by mutations in several genes, including genes not previously associated with cancer. Such resistant tumours can, however, be effectively addressed with novel combinations of FDA approved drugs. The most effective combinations almost always include non-cancer drugs, and as such offer drug discovery companies a unique opportunity to test and profile novel combinations with both marketed drugs and those in development.
