odegradable Alginate Microsphere (“188RNL-BAM”), is designed to treat many solid organ cancers including primary and secondary liver cancers by intra-arterial injection.

On April 26, 2024, we acquired all of the right, title and interest in a cerebrospinal fluid cancer diagnostic portfolio known as the CNSide® Platform from Biocept, Inc. (“Biocept”), which is currently being utilized in the ReSPECT-LM clinical trial funded by the Cancer Prevention and Research Institute of Texas (“CPRIT”). In connection with our business plan for developing the CNSide™ Platform, we formed CNSide Diagnostics, LLC (“CNSide Diagnostics”), a wholly owned subsidiary of the Company, and our board of directors appointed a board of managers for CNSide Diagnostics. We are planning for the CNSide Cerebrospinal Fluid Tumor Cell Enumeration test (the “CNSide™ Test”), which is a laboratory developed test (“LDT”), to be re-introduced to the U.S. market starting in the second quarter of 2025 after we complete a number of steps related to certifications, state licensure, payor coverages, reimbursement codes and financing. 

In March 2025, we moved our headquarters to Houston, Texas, in proximity to world-class cancer institutions and researchers.

Our most advanced investigational drug, REYOBIQ™, is a patented radiotherapy potentially useful for patients with CNS and other cancers. We announced in March 2025 that the U.S. Food and Drug Administration (“FDA”) conditionally accepted the proprietary name REYOBIQ™ to be used by us for rhenium (186Re) obisbemeda. Preclinical study data describing the use of REYOBIQ™ for several cancer targets have been published in peer-reviewed journals and reported at a variety of medical society peer-reviewed meetings. Besides GBM, LM and PBC, REYOBIQ™ has been reported to have potential applications for head and neck cancer, ovarian cancer, breast cancer and peritoneal metastases.

 The REYOBIQ™ technology was part of a licensed radiotherapeutic portfolio that we acquired from NanoTx, Corp. (“NanoTx”) on May 7, 2020. The licensed radiotherapeutic has been evaluated in preclinical studies for several cancer targets and we have an active $3.0 million award from U.S. National Institutes of Health/National Cancer Institute which is expected to provide financial support for
