SUNY Downstate Startup Company Secures Over $1 Million in Seed Funding Investment for Advancement of Proprietary Cancer Companion Diagnostic Test

Research findings promise new cancer diagnostics and therapeutics to identify and select patients who can benefit from a new class of cancer drugs

Brooklyn, NY— Concarlo Holdings, LLC, a newly-formed startup biotechnology company based on SUNY Downstate research, closed today on more than $1 million in seed funding to advance the company's proprietary cancer companion diagnostic test. The test, now in early clinical validation studies, will allow oncologists to identify and select patients who can benefit from a new, important class of cancer drugs called CDK4 inhibitors (Cdk4i), recently approved by the US Federal Drug Administration (FDA) and international regulatory agencies.

Concarlo's seed investors include several private investors, as well as the Accelerate NY Seed Fund, which focus on emerging company opportunities in the lower regions of New York State.

The test is based upon discoveries made by Dr. Stacy Blain, Ph.D., an Associate Professor in Downstate's Pediatric and Cell Biology departments. Specifically, the test exploits Dr. Blain's work on CDK4 regulation in breast cancer. Concarlo's ApY is a companion diagnostic used to identify patients responsive to CDK4 inhibitory therapies. It will inform doctors and patients whether this class of cancer drugs will have any effect on a patient's particular tumor.

Concarlo has also initiated a program to develop a new drug, IpY, which addresses the drug resistance that can develop with Cdk4i treatment. The seed idea for this work was recently published in the prestigious journal Molecular Cancer Research, accessible here.

"Dr. Blain's research programs help us understand the signals related to how certain cells are regulated and how they contribute to cancer progression," said Downstate president Wayne J. Riley, M.D. "The diagnostic test being developed at Concarlo will help target appropriate therapies and reduce costs-an issue pertinent to our patients' care."

"The formation of Concarlo, and the development of these technologies in the commercial setting are logical extensions of the work I have been doing in my Downstate lab for the last 15 years," said Concarlo founder Dr. Blain. "The location of the Downstate Incubator, literally across the street from Downstate, encouraged me to make this important transition." "The goal of the incubator is to provide a nurturing and supportive environment to help scientists bring discoveries from the laboratory to the bedside," said Eva Cramer, Ph.D., President of the Downstate Biotech Incubator. "We are very proud of Concarlo and their great progress, and look forward to future successes."

"New treatments like Pfizer's palbociclib, or Ibrance, mark a significant advance in cancer therapy, but they are not effective in all patients," said Brandy Houser, Investment Manager at the Accelerate NY Seed Fund. "Finding out which patients are best suited for this treatment will eliminate negative side effects for those not suited for this type of treatment. Concarlo's work promises to identify those breast cancer patients suited to this line of therapy, but, very possibly, to also identify appropriate patients with other types of cancer. Together with our partner Empire State Development Corp., we are very excited to work with Dr. Blain and the Concarlo team."

"It is very gratifying when our scientists' academic research findings can be directly translated into novel approaches to assess and treat human diseases," said David Schoenhaut, Ph.D., Director of Downstate's Office of Technology Commercialization. "Obtaining private sector investment from funders such as the Accelerate NY Seed Fund through the licensing and company formation process has proven to be an effective and expedient path to realizing this goal for many institutions."
