Company to Host Conference Call Today, May 3, at 4:30pm ET

BOCA RATON, Fla., May 03, 2023 (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, today announces its financial results for the quarter ended March 31, 2023 and provides a business update.

Q1 2023 Corporate Highlights:  

DN-TNF Platform Highlights (XPro™ and INB03™):

  • AD02 blinded randomized Phase 2 clinical trial in patients with early Alzheimer’s Disease (AD) continues to enroll in Australia and Canada. The company is actively pursuing other regulatory venues to expand the clinical trial footprint. The company announced consolidation of the mild ADi and Mild Cognitive Impairment Phase 2 programs into a single trial to improve the efficiency and align the program with the most probable Phase 3 design. Discussions with the FDA have provided a clear pathway to lifting the clinical hold before the end of year.
  • Announced data in acute mdx model of Duchene’s Muscular Dystrophy (DMD) and formed DN02, Inc. a wholly owned subsidiary to facilitate partnering and development of DN-TNF in the treatment of DMD. Results from the long-term D2.mdx model are expected soon. Data presented to date suggests DN-TNF may improve treatment from boys with DMD by promoting muscle fiber regeneration and eliminating the need for corticosteroids. Corticosteroids, the current standard-of-care, is responsible for many of the metabolic and physical complications suffered by boys with DMD.
  • Presented additional data on combination of INB03™ DN-TNF with trastuzumab-deruxtecan (Enhertu™, TDxd) at the American Association for Cancer Research (AACR) annual scientific meeting in April showing that triple negative breast cancer (TNBC) often express MUC4. MUC4 expressing cancers, breast cancer, HER2+ breast cancer, TNBC, gastric and pancreatic cancer, are candidates for combination therapy with DN-TNF. In pre-clinical models, INB03™ DN-TNF reduced MUC4 expression to decrease resistance to immunotherapy including tyrosine kinase inhibitors (TKIs), trastuzumab and TDxd. The Company is developing a novel DN-TNF-bioconjugate compound with distinct intellectual property protections and testing in a variety of animal models in preparation of launching a strategic partnering program in oncology.
  • Announced pre-clinical, mouse model data that support the use of XPro™ as an early treatment following Traumatic Brain Injury (TBI) to prevent the development of amyloid pathology. Data shows neuroinflammation drives the development of amyloid pathology after TBI and can be prevented by neutralizing sTNF with XPro™. These data implicated TBI as a contributing factor for the development of AD.

INKmune™ Platform:

  • IND filed in April for the use of INKmune™ to treat patients with metastatic castration-resistant prostate cancer (mCRPC) in the US. Excluding skin cancer, prostate cancer is the most common cancer in men. The Phase I/II design will enroll patients at several medical centers in the US.
  • Additional sites have opened to support the ongoing Phase 1 trial in high risk MDS/AML. A second site in the UK, The Royal Hallamshire Hospital at Sheffield University Medical School treated their first patient on March 9th. A third site in Europe, Attikon University Hospital in Athens, Greece, has opened for recruitment and INKmune™ is being imported into Greece in readiness for patient enrollment.
  • Our CSO Mark Lowdell co-hosted a session at the Innate Killer Summit in La Jolla in March focused on the expanding world of memory-like NK cells in cancer immunotherapy and the ability of INKmune™ to generate these cells in vivo.
  • On June 1st, Dr Lowdell will present the opening plenary presentation in the Presidential Session at the annual International Society of Cell & Gene Therapy (ISCT) where he will share the latest data on INKmune.

Upcoming Events and Milestones:

  • Top-line results for the Phase 2 XPro trial for treatment of neuroinflammation as a cause of Alzheimer’s Disease is expected in 2H 2024.
  • Initiate a Phase 2 trial of XPro in patients with Treatment Resistant Depression that is partially funded by a $2.9 million NIH grant upon resolution of the FDA manufacturing review.
  • Additional open-label Phase 1 trial data of INKmune™ in high-risk MDS/AML in 2023.
  • Opening of a Phase I/II trial studying INKmune™ in prostate cancer upon the acceptance of the IND by the FDA.

Financial Results for the Quarter Ended March 31, 2023:

Net loss attributable to common stockholders for the quarter ended March 31, 2023 was approximately $6.5 million, compared to approximately $6.9 million during the quarter ended March 31, 2022.

Research and development expense totaled approximately $4.1 million for the quarter ended March 31, 2023 compared to approximately $4.3 million during the quarter ended March 31, 2022.

General and administrative expenses were approximately $2.3 million for the quarter ended March 31, 2023 compared to approximately $2.3 million during the quarter ended March 31, 2022.

Other expense was approximately $0.1 million for the quarter ended March 31, 2023 compared to approximately $0.4 million during the quarter ended March 31, 2022.

In addition, the Company received research and development rebates from Australia and the United Kingdom during the three months ended March 31, 2023 that totaled approximately $6.5 million.

As of March 31, 2023, the Company had cash and cash equivalents of approximately $51.0 million.

About XPro™

XPro™ is a next-generation inhibitor of tumor necrosis factor (TNF) that is currently in clinical trial and acts differently than currently available TNF inhibitors in that it neutralizes soluble TNF (sTNF), without affecting trans-membrane TNF (tmTNF) or TNF receptors. XPro™ could have potential substantial beneficial effects in patients with neurologic disease by decreasing neuroinflammation. For more information about the importance of targeting neuroinflammation in the brain to improve cognitive function and restore neuronal communication visit this section of the INmune Bio’s website.

About INKmune™

INKmune™ is a pharmaceutical-grade, replication-incompetent human tumor cell line which conjugates to resting NK cells and delivers multiple, essential priming signals to convert the cancer patient’s resting NK cells into tumor killing memory-like NK cells.  INKmune™ treatment’s effect on NK cells is akin to treatment with at least three cytokines in combination (IL-12, IL-15, IL-18) to form memory-like NK cells.  In patients, INKmune™ primed tumor killing NK cells persist for more than 100 days and function in the in the hypoxic TME because due to upregulated nutrient and mitochondrial survival proteins.  INKmune™ is a patient friendly therapy that can be easily transported, stored and delivered to the patient by a simple intravenous infusion without the need for patient conditioning or premedication. INKmune™ is tumor agnostic; it can be used to treat many types of NK-resistant tumors including leukemia, lymphoma, myeloma, lung, ovarian, breast, renal and nasopharyngeal cancer.  INKmune™ is treating patients in an open label Phase I trial in high-MDS/AML in the UK and Europe.  The company plans an open label Phase I/II trial in metastatic castration-resistant prostate cancer in the US this year.
