Concarlo awarded patent for novel therapeutic peptide for drug-resistant breast cancer

Concarlo Holdings has received a US patent for IpY, a novel therapeutic peptide that addresses drug-resistant breast cancer by targeting a unique cellular pathway — p27Kip1. The patent is the latest step in Concarlo’s journey to commercialize revolutionary medicines for metastatic breast cancer.

Concarlo has also announced that a new provisional patent application has been filed for modified versions of the therapeutic peptide that are believed to exhibit enhanced bioavailability. Concarlo is a Brooklyn, New York-based biotechnology innovator dedicated to developing sophisticated, targeted therapies and diagnostics in the oncology space. The IpY technology is the first to address the high incidence of drug-refractory disease that develops with currently available CDK4 inhibitor (CDK4i) treatments. Such a solution has the potential to drastically increase overall survival of breast cancer patients.

The recent introduction of CDK4i drugs, a class of medicines that directly targets the CDK4/6 pathway implicated in many malignancies, has had a significant impact on the way in which metastatic breast cancer is managed. However, such therapeutics are associated with patients transitioning to a treatment-resistant form of the condition, despite initial extended periods of remission. Backed by more than 20 years of research and development expertise, Concarlo has developed IpY and a companion diagnostic, ApY, to effectively overcome the issue of CDK4i resistance and roll out a more targeted treatment approach for optimized patient outcomes.

“Despite the clinical efficacy of CDK4 inhibitors, we’re seeing that primary or secondary resistance to therapy is presenting a significant challenge to overall survival,” said Dr. Dominique Bridon, Chief Development Officer at Concarlo. “With the IpY technology and its unique mechanism of action, we’re effectively targeting CDK4 while simultaneously inhibiting another target — CDK2 — which has been found to be a key molecular player in the development of drug resistance. In doing so, we are the first company to successfully address the CDK4i resistance issue to provide long-term durable tumour arrest. Combined with its highly specific targeting and low toxicity profile, the positive impact of this drug on the breast cancer treatment landscape is hard to understate.”

Concarlo was formed in 2016 and is supported by a team of internationally renowned experts forming its Scientific Advisory Board. To date, the company has raised more than $3.1 million to support the development, improvement, and commercialization of its IpY and ApY technologies to bring a precision medicine approach to breast cancer management. The newly issued patent for IpY and the provisional patent application for modified versions of the peptide are the first key milestones in Concarlo’s plan to build an extensive patent estate to maintain market exclusivity for its clinically relevant therapeutics.
