Spexis has worldwide rights to ColiFin^® ex-Europe and is focused on developing the product first for the U.S. market. Spexis is preparing a Phase 3 program in adult and adolescent CF patients with moderate to severe lung function impairment and chronic PA lung infection. The Phase 3 program includes the COPILOT safety and tolerability pilot clinical trial. Its objective is to evaluate and confirm the use of once or twice daily dosing for COPA, the planned single efficacy and safety Phase 3 trial. PA infection accounts for two-thirds of CF chronic lung infections and is the leading cause of lung function decline and mortality in CF patients.

Prior to starting the COPILOT pilot trial or COPA Phase 3 trial with ColiFin®, Spexis needs to secure additional funding but is continuing to advance clinical trial readiness through a variety of internal and externally contracted clinical operations activities. In addition, as reported in July, the Company had originally planned to engage clinical trial sites in Ukraine and Russia. In view of the ongoing Ukraine war, the trial was expanded to sites in other countries. The process of site initiation is proceeding well, and the COPILOT trial is now planned to start in H1 of 2023, and aims to provide dosing data for COPA, which is now expected to initiate in H2 2023.

Balixafortide, discovered from Spexis’ macrocycle platform, is a potent, specific and highly selective inhibitor of CXCR4, which plays a role in a number of tumor types as well as non-oncology indications. As reported in the Company’s July 28, 2022 update, Spexis is analyzing existing clinical and preclinical data with balixafortide to help determine the appropriate path forward for this program, including potential new indications, and recently published data demonstrating synergistic efficacy in combination with docetaxel in metastatic prostate cancer. These data and others in development will inform future decisions on the program. In addition, this fall, the Company expects to report the results of its recently completed safety/PK study of balixafortide in human subjects with renal impairment. This clinical trial was initiated pursuant to interactions with the FDA as a condition to potentially include such patients in any future labeling claim. The Company also expects to share additional data and more details on its development plan for balixafortide later in 2022.

Inhaled murepavadin (iMPV), a novel inhaled therapeutic specifically targeting PA and discovered from Spexis’ macrocycle platform, is currently in a Phase 1 study in healthy volunteers to evaluate safety and tolerability of single and multiple ascending doses (SAD/MAD). The study is ongoing and top-line data are expected by the end of this year. Potential indications that could be eventually targeted with iMPV include CF, nCFBE and COPD in patients with chronic PA infection.

OMPTA is another class of products derived from application of its macrocycle platform. Spexis was previously awarded funding from CARB-X (Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator), a global non-profit partnership accelerating antibacterial products to address drug-resistant bacteria. This funding is to support the development of thanatin derivatives belonging to Spexis’ novel Outer Membrane Protein Targeting Antibiotic (OMPTA) class of therapeutics to potentially treat life-threatening infections caused by difficult-to-treat Gram-negative bacteria.   This work is almost entirely funded by CARB-X, continues to move forward as planned, and was recently presented at the Gordon Research Conference New Antibacterial Discovery and Development event.

Macrocycle platform

Macrocycles are a proven chemical class of pharmaceutical therapeutics occupying the chemical space between small molecules and biologics. With a unique conformational balance of flexibility and rigidity, macrocycles can act on both extracellular and intracellular targets that are not easily accessible by other chemical classes. Indeed, since 2014, some 19 distinct macrocycle compounds have been approved by various drug regulatory authorities worldwide, involving a wide range of diseases and indications. More recently, with the emergence of the field of molecular glues and protein-protein interactions/degraders, macrocycles are increasingly recognized as possessing significant potential to target unique molecular targets and be combined with complementary technologies. Spexis possesses two distinct, highly diverse and very well characterized macrocycle libraries, together with deep data on same: PEMfinder®, which is comprised of peptidomimetic macrocycles, and MACROfinder®, which are small molecule macrocycles. Each library has distinct applications depending on the targets in question. In addition, Spexis has several pre-clinical leads for various indications which have already been considerably characterized. Spexis is looking to partner either these pre-clinical leads or the entire platform itself, potentially in combination with complementary technologies.

Financial results
In the first half of 2022, total loss was CHF 10.0 million, primarily driven by R&D expenses related to preparation of the ColiFin® Phase 3 program and other operating expenses. Total cash position was CHF 7.0 million (cash and cash equivalents) as of June 30, 2022, which is expected to finance operations through January 2023.

On July 28, 2022, Spexis announced that it had renewed an equity-linked financing arrangement with the French company IRIS. The remaining CHF 13.6 million of the original agreement was replaced with a new equity-linked financing agreement which may raise, as needed, a gross amount of up to CHF 15.0 million over the period of two years.
