Insights
The announcement of XPro's 24-month stability is a positive development for INmune Bio, potentially easing the logistical challenges associated with the global distribution of biopharmaceuticals. Stable biologic formulations at 2-8C reduce the risk of product degradation during shipping, a critical consideration in maintaining drug efficacy upon delivery. This aligns with industry norms for pegylated cytokines and leverages established temperature-controlled supply chains. For investors, this indicates a maturity in the product's lifecycle, moving closer to Phase III readiness and commercial distribution, which can play an integral role in the potential market penetration and revenue projection for the drug.
The filing of a patent for a novel immunogenicity assay specific to XPro is a strategic move to protect the proprietary technology and potentially extend the commercial life of INmune Bio's product. Intellectual property fortification is a vital competitive edge, particularly in the biotech industry. From an investor's standpoint, patent applications may not only offer a glimpse into the company's innovative capabilities but may also provide a moat against competition. This can translate into a sustained revenue stream, assuming the patent holds and the drug proves to be efficacious in treating Alzheimer's, a condition with a significant unmet medical need.
The progress towards completing Phase 2 clinical trials for Alzheimer’s Disease is important in determining XPro's future. Positive results could lead to accelerated demand for the treatment, given the limited effective options currently available for neuroinflammatory conditions. Investors often look for these milestones as indicators of a biotech company's potential success. Continued alignment with the projected timelines reassures stakeholders of the company's execution capabilities. However, it's imperative to note that the results of the trial will significantly influence the drug's prospects and, consequently, the company's stock performance.
Boca Raton, Florida, April 23, 2024 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease, is delighted to announce the successful completion of the extended stability validation for XProTM continuous storage in solution at 2-8C. The 24 and 30-month stability test samples passed all chemistry and potency assays; allowing the Company to make a conservative claim of 24-month stability. The 24-month stability claim is consistent with other pegylated cytokines, such as alpha-interferon, and allows the Company to design a global supply chain using proven and established systems. With this data, the company can benefit from such existing systems that use temperature controlled and monitored shipment of liquid-formulation drugs at 2-8C, which is routine across the pharmaceutical industry. The 24-month stability data confirms that XProTM can mirror these established supply chain strategies.
“24-month stability is essential for our plans to use XProTM as we move towards Phase III and commercial applications and allows us to utilize a well-established global distribution system,” said RJ Tesi, MD. “Distribution is only part of the product supply equation. Use at the point of care by the patient is equally important. We hope to provide XProTM in a pre-filled syringe format for easy home storage and self-administration by AD patients and their caregivers.”
In addition to the 24-month stability progress, the Company further announced that it has filed a patent application after it successfully developed an anti-drug antibody assay for XProTM that mitigates false positive readings associated with the application of conventional bridging and affinity capture elution (ACE) formats. Due to XProTM’s unique mechanism, namely trimerization and exchange of monomeric units, the application of such conventional assays can be problematic. The detection of anti-drug antibodies for XProTM in human serum according to the new assay utilizes a novel ACE-AG format. Details of the assay will be disclosed in the forthcoming 18th Workshops on Recent Issues in Bioanalysis (WRIB) in San Antonio, TX this coming May 7, 2024, with a poster titled “Anti-Drug Antibody (ADA) Assay for XPro 1595, a Self-Assembling Trimer: Alternative to Standard Bridging or ACE Approaches”. “This new assay is the product of a unique challenge and applied innovation, which has now resulted in the filing of a patent application adding value to the XPro1595 franchise” said Joshua Schoonover, the Company’s General Counsel.
Tho Company remains on track in line with prior guidance to complete its Phase 2 clinical trial involving the use of XProTM for the treatment of Alzheimer’s Disease in patients with biomarkers of neuroinflammation.
