In addition, we have completed our initial analysis of further indication development potential for balixafortide. Based on our analysis, we are excited to announce balixafortide’s new focus on the treatment of PDAC where patients have long faced bleak and limited treatment options. Balixafortide’s well-documented and encouraging selective antagonism of the CXCR4 chemokine receptor and the new preclinical research illustrating its potential in PDAC have encouraged the company to focus our resources on the clinical development of balixafortide in this indication. We look forward to providing additional updates as our novel macrocycle derived pipeline continues to advance.” Pipeline status and plans The plans outlined below regarding the further development of various programs are subject to Spexis raising additional funds and/or entering into partnering agreements. Lead Program, ColiFin®: Spexis is committed to progressing its lead program ColiFin®, which is currently being developed to treat chronic lung infections in cystic fibrosis patients, but which also has strong therapeutic potential in non-CF bronchiectasis (nCFBE) and chronic obstructive pulmonary disease (COPD), as these patients also suffer from chronic Pseudomonas aeruginosa (PA) lung infections. ColiFin® has been approved in the EU as an inhaled therapeutic and holds Orphan Drug and QIDP designations in the U.S. The company has worldwide rights to ColiFin® ex-Europe and is preparing a Phase 3 program in CF patients which includes the COPILOT safety and tolerability trial, and the COPA efficacy trial. COPILOT is expected to initiate prior to the end of 2023. Capital commitments from SPRIM Global Investments (SGI) and additional institutional investors totaling USD $7.5 million to-date will enable the near-term initiation of COPILOT. The company’s clinical trial partnership with SGI, which includes debt facilities, is expected to provide Spexis with up to half of the Phase 3 clinical development costs of ColiFin®. Future milestones are contingent on securing additional capital and/or partnering agreements. Balixafortide: Today Spexis announced plans to pursue the clinical development of balixafortide, the Company’s potent and selective macrocyclic CXCR4 inhibitor, in PDAC, an aggressive form of pancreatic cancer with a poor survival rate. Balixafortide has been well-studied in clinical trials and has demonstrated a promising safety profile both as a monotherapy as well as in combination with other therapies. PDAC has been traditionally resistant to immunotherapy due to a combination of tumor microenvironment features unique to PDAC, but recent preclinical studies have shown the successful modulation of these factors using anti-CXCR4 antibodies, anti-programmed cell death protein 1 antibodies (anti-PD-1) and focal adhesion kinase inhibitors (FAKi). The combination of anti-CXCR4 antibodies, anti-PD-1 antibodies and FAKi led to a significantly decreased metastatic rates in a well-validated PDAC murine liver metastasis model. These results were subsequently validated substituting anti-CXCR4 antibodies for balixafortide. The synergistic effects of targeting PDAC with this regimen represents a unique opportunity for balixafortide to address the significant unmet need that has persisted in the fight against pancreatic cancer. PDAC accounts for more than 90% of pancreatic cancer diagnoses, and its poor survival rate is due to limited treatment options and the absence of an early diagnosis in many patients. The average 5-year survival rate is less than 10%, and pancreatic cancer represents an increasing and worrying proportion of cancer deaths. In 2023, the American Cancer Society projects over 50,000 patients will die of pancreatic cancer in the United States, the third-leading cause of cancer deaths. Despite a growing patient population, treatment options have remained limited, increasing the demand for novel therapeutics and approaches. Inhaled murepavadin (iMPV): Earlier in 2023, Spexis announced safety and pharmacokinetics results from the company’s first-in-human study with inhaled murepavadin, its novel macrocycle compound. Results indicated that iMPV was well tolerated at all dose levels and no serious adverse events were reported in the Phase 1 double-blind, randomized, placebo-controlled trial. iMPV was derived from Spexis’ macrocycle platform, validating its potential to generate clinically relevant therapeutics capable of drugging specific targets across a variety of rare diseases. The study was supported by the European Innovative Medicines Initiative (IMI), with iMPV successfully targeting the outer membrane of Pseudomonas aeruginosa, showing activity against highly resistant strains of bacteria. Spexis remains committed to addressing antibiotic resistance and progressing iMPV through the clinic. Macrocycle platform: Macrocycles remain a key differentiator at Spexis as this burgeoning area of drug discovery yields additional promise. The company’s leadership in the space represents an opportunity to yield novel therapeutics and the potential to combine macrocycles with a wide variety of complementary technologies, including, but not limited to, molecular glues and degraders. Spexis possesses two distinct, highly diverse and very well characterized macrocycle libraries, together with deep data on each: PEMfinder®, which is comprised of peptidomimetic macrocycles, and MACROfinder®, which are small molecule macrocycles. Each library has distinct applications depending on the targets involved, with several pre-clinical characterized leads for various indications having already been identified and characterized. As one example of the power of Spexis’ macrocycle platform, in June of this year, Spexis announced the publication of promising results for a novel class of macrocyclic, peptidomimetic antibiotics in Science Advances demonstrating potent in vitro and in vivo antimicrobial activity against MDR and XDR Enterobacteriaceae, including carbapenem-resistant and colistin-resistant strains. The novel antibiotics were developed by Spexis in close collaboration with Professor Oliver Zerbe’s group at the University of Zurich with substantial funding by Innosuisse and CARB-X. Corporate updates Spexis announced the appointment of Gonçalo Bernardes, Ph.D., as acting Head of Chemical Biology. Dr. Bernardes is a Full Professor of Chemical Biology and a Fellow of Trinity Hall College, Cambridge. He has co-founded companies using technologies developed in his lab and has been awarded three European Research Council grants, as well as awards from the Royal Society of Chemistry, International Chemical Biology Society, European Federation of Medicinal Chemistry and The Blavatnik Family Foundation. Dr. Bernardes also serves as a Senior Fellow at Flagship Pioneering, the largest global venture incubator. He completed his Ph.D. at the University of Oxford, U.K., and his postdoctoral work at the Swiss Federal Institute of Technology (ETH) in Zürich. Multiple discoveries made in his lab have been translated into leading biopharmaceutical companies. At Spexis Dr. Bernardes will focus his efforts on the company’s leading and proprietary macrocycle platform to produce novel therapeutics for the treatment of cancer and rare diseases. The Company expects to announce specific programs already in development in collaboration with Prof. Bernardes in the coming weeks and months. Financial results In the first half of 2023, Spexis’ total loss was CHF 3.9 million, primarily driven by research and development (R&D) expenditures of CHF 2.7 million.
