Adva-27a Anticancer Drug
Adva-27a is a small molecule designed for the treatment of aggressive forms of cancer. A Topoisomerase II inhibitor, Adva-27a has been shown to be effective at destroying Multidrug Resistant Cancer cells including Pancreatic Cancer cells, Breast Cancer cells, Small-Cell Lung Cancer cells and Uterine Sarcoma cells (Published in ANTICANCER RESEARCH, Volume 32, Pages 4423-4432, October 2012). We are the direct owner of all patents pertaining to Adva-27a including U.S. Patents Number 8,236,935 and 10,272,065.
In December 2022, we entered into a research agreement with the Jewish General Hospital (“JGH”), to conduct the IND-enabling studies of Adva-27a (the “Research Agreement”). In August 2023, we were informed by the JGH that the lab results on testing of the Adva-27a molecule were not favorable. After conclusion of an internal review of the lab results on November 2, 2023, we provided notice to JGH of termination of the Research Agreement. We have now paused the IND-enabling studies of Adva-27a pending a review of the possibility of chemical modification of the compound to address the suboptimal performance of the molecule in certain studies.
K1.1 Anticancer mRNA
In June 2021, we initiated a new research project in which we set out to determine if certain mRNA molecules can be used as anticancer agents. The data collected to date have shown that a selected group of mRNA molecules are capable of destroying cancer cells in vitro including multidrug resistant breast cancer cells (MCF-7/MDR), ovarian adenocarcinoma cells (OVCAR-3), and pancreatic cancer cells (SUIT-2). Studies using non-transformed (normal) human cells (HMEC cells) showed that these mRNA molecules had little cytotoxic effects. These new mRNA molecules, bearing the laboratory name K1.1, are readily adaptable for delivery into patients using the mRNA vaccine technology.
In April 2022, we filed a provisional patent application in the United States covering the subject mRNA molecules.
We recently concluded an agreement with a specialized partner for the purposes of formulating our K1.1 mRNA molecules into lipid nanoparticles, ready for use to conduct studies in xenograft mice. We anticipate commencing such studies later this year.
SBFM-PL4 Coronavirus Treatment
The initial genome expression products following infection by Betacoronavirus, the causative agent of COVID-19, are two large polyproteins, referred to as pp1a and pp1ab. These two polyproteins are cleaved at 15 specific sites by two virus encoded proteases, called Mpro and PLpro, to generate 16 different non-structural proteins essential for viral replication. Mpro and PLpro represent attractive anti-viral drug development targets as they play a central role in the early stages of viral replication. PLpro is of particular interest as a therapeutic target in that, in addition to processing essential viral proteins, it is also responsible for suppression of the human immune system making the virus more life-threatening. PLpro is present only in Betacoronaviruses, the subgroup of Coronaviruses represented by the highly pathogenic SARS-CoV, MERS-CoV, and SARS-CoV-2.
Our Anti-Coronavirus research effort has been focused on developing an inhibitor of PLpro and, on May 22, 2020, we filed a patent application in the United States covering composition subject matter pertaining to small molecules for inhibition of the Coronavirus PLpro as well as Mpro.
In February 2022, we expanded our PLpro inhibitors research effort by entering into a research agreement with the University of Arizona for the purposes of conducting research focused on determining the in vivo safety, pharmacokinetics, and dose selection properties of three University of Arizona owned PLpro inhibitors, to be followed by efficacy testing in mice infected with SARS-CoV-2 (the “Research Project”). Under the agreement, the University of Arizona granted the Company a first option to negotiate a commercial, royalty-bearing license for all intellectual property developed by University of Arizona under the Research Project. In addition, the Company and the University of Arizona entered into an option agreement (the “Option Agreement”) whereby the Company was granted a first option to negotiate a royalty-bearing commercial license for the underlying technology of the Research Project. On September 13, 2022, we exercised our options, and on February 24, 2023, we entered into an exclusive worldwide license agreement with the University of Arizona for all of the technology related to the Research Project.
We have recently expanded our objective to include the development of an injectable candidate of first-in-class PLpro inhibitor to treat SARS-CoV2 and potentially SARS-CoV and MERS-CoV infection in patients who could not use Paxlovid, Molnupiravir, or Remdesivir, due to concerns about drug interaction and possible ‘rebound’ infections and other side effects.
