Applied DNA Submits PCR-based Monkeypox Virus Diagnostic Test for Approval to New York State Department of Health

- Submitted by Clinical Lab Subsidiary for its Use; Subsidiary to Manufacture the Diagnostic Kit if Approved -

Applied DNA Sciences, Inc. (NASDAQ: APDN) ("Applied DNA" or the "Company"), a leader in PCR-based DNA technologies, announced today that its wholly-owned clinical laboratory subsidiary, Applied DNA Clinical Labs, LLC ("ADCL"), has submitted to the New York State Department of Health (NYSDOH) a validation package for its Company-developed monkeypox virus test in support of a request for full approval as a form of NYSDOH Laboratory Developed Test (LDT). The PCR-based diagnostic is designed to identify the genetic signature of the Clade II variant of the monkeypox virus that is currently prevalent in the U.S. If approved by NYSDOH, the test will be used to power ADCL's monkeypox testing services.

Named the Linea™ Monkeypox Virus 1.0 Assay, the test would be ADCL's second successful LDT in less than one year if approved by the NYSDOH. The test is part of ADCL's high-throughput infectious disease testing offering centered on high-volume testing for infectious diseases that can reoccur within a population. ADCL's Linea™ 2.0 COVID-19 Assay received conditional approval as an LDT from NYSDOH in January 2022 and currently powers ADCL's COVID-19 testing services. If approved, monkeypox testing will be performed at ADCL's CLEP/CLIA molecular diagnostics laboratory in Stony Brook, N.Y., utilizing proven workflows to ensure accurate results and competitive turnaround times.

"Our pursuit of monkeypox testing via LDT combines what we believe to be the quickest regulatory path for diagnostic approval with our proven ability to deliver short turnaround time-to-results that, as COVID-19 has taught us, can help contain virus spread," stated Dr. James A. Hayward, president and CEO of Applied DNA. "Upon NYSDOH approval, ADCL has the testing capacity to deploy to help keep New Yorkers safe. Moreover, as the test kit manufacturer, we maximize the control over our own supply chain to ensure both quality and availability."
