Phoenix Molecular Designs Receives FDA Clearance to Begin Phase 1/1b Clinical Trial with PMD-026, a First-in-Class RSK Inhibitor, Targeting Advanced Breast Cancer

SAN DIEGO, and VANCOUVER, British Columbia, Sept. 23, 2019 /PRNewswire/ -- Phoenix Molecular Designs (PhoenixMD), a clinical stage biotechnology company developing precise cancer therapeutics targeting essential kinases, received clearance from the Food and Drug Administration (FDA) for PhoenixMD's Investigational New Drug (IND) application for its proprietary PMD-026. That clearance permits PhoenixMD to begin patient enrollment into its Phase 1/1b clinical trial, which is expected to start in the United States during the fourth quarter of 2019.

"Our IND clearance marks an important developmental milestone for PhoenixMD," said Sandra Dunn, Ph.D., chief executive officer of PhoenixMD. "To our knowledge, PMD-026 is the only purpose-built agent designed specifically to treat triple-negative breast cancer (TNBC). Additionally, we will be assessing the potential of PMD-026 to extend beyond TNBC and into other forms of advanced breast cancer."

PMD-026 is a proprietary first-in-class orally-available RSK (kinase) inhibitor being developed to treat certain forms of breast cancer. The Phase 1/1b clinical trial will evaluate safety, tolerability, pharmacokinetics and anti-tumor activity of PMD-026 in patients with advanced disease and a sub-group of women with TNBC. Importantly, this trial will include a CAP/CLIA certified companion diagnostic designed to detect RSK2 activation in breast tumors and to then correlate it with response to PMD-026. This is a new approach for the treatment of cancer that hinges on precision medicine and functional kinomics.

"TNBC patients with metastatic disease have limited treatment options and new drugs have not generally been specifically developed based on the biology of this type of tumor," said Gerrit Los, Ph.D., chief scientific officer of PhoenixMD. "We have had substantial interest from some of the top clinical oncology centers eager to participate in our upcoming trial, underscoring the need for treatment options for women with advanced disease."

About PMD-026
PhoenixMD's lead candidate, PMD-026, is the first RSK inhibitor being developed for the treatment of TNBC. PMD-026 was precisely designed for TNBC because RSK2 was specifically identified as the key kinase, out of 519 kinases, that drives the growth of this breast cancer subtype. Preclinical data shows the potential for PMD-026 to be effective alone or in combination with conventional chemotherapies. It has the potential to be a platform technology for chemotherapy, hormone therapy and/or immunotherapy sensitization for a wide range of refractory cancers in the future.
