Company to Host Conference Call Today, March 28, at 4:30pm ET

BOCA RATON, Fla., March 28, 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, today announces its financial results for the year ended December 31, 2023 and provides a business update.

Q4 2023 and Recent Corporate Highlights  

DN-TNF Platform Highlights (XPro™):

  • The AD02 randomized, blinded program for patients with Early Alzheimer's Disease remains on schedule to reach its final enrollment target by mid-2024, with top-line data expected to be presented approximately six months after the last patient is enrolled. The trial is currently active in North America, UK, EU, and the Pacific Rim.
  • INmune Bio and Cumulus Bioscience issued a joint press release highlighting seven AD patients who received weekly XPro™ treatment for four weeks experienced a statistically significant increase in Alpha wave frequency and power (p<0.05). Reduced Alpha power is associated with cognitive decline and the progression of Alzheimer's Disease. EEG, which is widely considered a gold standard for objectively measuring brain activity, offers valuable insights into neural connectivity. Neurological research has consistently shown a progressive decline in alpha band power and frequency in individuals with MCI and Alzheimer's disease.
  • INB03 cancer platform – poster was submitted to the 46th annual San Antionio Breast Cancer Symposium and associated data presented by Roxana Schillaci, Ph.D., of Instituto de Biología y Medicina Experimental in Buenos Aries, Argentina that shows that INB03 improves the potency of T-DXd in a model of immunotherapy resistant HER2+ breast cancer.

INKmune™ Platform:

  • The first patient was enrolled in the Phase I/II open label trial of INKmune™ in metastatic castration-resistant prostate cancer (mCRPC) in the final week of 2023. Enrollment of 3 patients in cohort 1 is complete and cohort 2 will open for enrolment after review of the first cohort by the Data Safety Monitoring Committee in mid-April. Phase I patient enrollment at all three dose levels is expected to be completed by September. and then roll directly into the phase 2 program. Patients receive three infusions of INKmune™ as out-patient treatment over two weeks and are monitored for four months for immunological and clinical responses.  Three dose levels of INKmune™ are being tested in a modified Bayesian Phase I/II trial.
  • We continue to assess other solid tumors as clinical targets for INKmune™. Currently IND enabling pre-clinical data are being generated to support a clinical trial in patients with renal cell cancer.   Initiation of a clinical trial in this indication is dependent of receipt of non-dilutive grant or similar type funding.
  • Mark Lowdell and team are investigating the role of NK cell dysfunction as a mechanism of carcinogenesis. Most recently we have shown that healthy individuals with the BRCA1 mutation, a marker of high risk of ovarian cancer, have dysfunctional NK cells compared to matched healthy, BRCA1 negative (BRCA1-ve) controls. These data support the concept of tumor immune surveillance by NK cells and its failure as a contribution to carcinogenesis. (Cancers 2024, 16, 1186.
  • The third patient for the INKmune™ AML program in UK and EU has been enrolled and subsequent to their completion of follow-up, the company will wind down the AML program to focus resources on the prostate-cancer program and other solid tumors.

Upcoming Events and Milestones:

  • Full enrollment in the Phase II XPro™ trial for treatment of neuroinflammation as a cause of Alzheimer’s Disease are expected mid-2024 followed by top-line data approximately 6 months from the last patient enrolled.
  • Initiate a Phase II trial of XPro™ in patients with Treatment-Resistant Depression 2H 2024.
  • Webinar on using XPro™ on the role of demyelination and myelin repair in AD in Q2, 2024.
  • Expect to complete enrollment in the Phase I portion of the mCRPC trial by end of Q3 2024 with data in Q4 2024. The Phase II portion is expected to complete enrollment in Q2, 2025 with data Q4, 2025.
  • Mark Lowdell, PhD, found and CSO has been awarded the prestigious 2024 ISCT Career Achievement Award in Cell & Gene Therapy by the International Society of Cell and Gene Therapy. This distinction is awarded to an individual who has made a significant impact during their career, advancing the field of cell and gene therapy through their longstanding service in the Society’s Three Pillars of Value: Academia, Regulatory/Quality Operations, and Commercialization. Prof. Lowdell will receive the award at the 2024 annual meeting of the ISCT meeting in Vancouver, Canada in May.

Financial Results for the Year Ended December 31, 2023:

  • Net loss attributable to common stockholders for the year ended December 31, 2023, was approximately $30.0 million, compared to approximately $27.3 million during the year ended December 31, 2022.
  • Research and development expenses totaled approximately $20.3 million for the year ended December 31, 2023, compared to approximately $17.1 million during the year ended December 31, 2022.
  • General and administrative expenses were approximately $9.6 million for the year ended December 31, 2023, compared to approximately $9.3 million during the year ended December 31, 2022.
  • Other expense, net was approximately $0.3 million for the year ended December 31, 2023, compared to approximately $1.3 million during the year ended December 31, 2022.
  • As of December 31, 2023, the Company had cash and cash equivalents of approximately $35.8 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 (mlNK cells).  INKmune™ treatment converts the patient’s own NK cells into mlNK cells. In patients, INKmune™ primed tumor killing NK cells persist for more than 100 days and function in the hypoxic TME because due to upregulated nutrient and mitochondrial survival proteins.  INKmune™ is a patient friendly that does not require pre-medication, conditioning or additional cytokine therapy given to the patients. INKmune™ is easily transported, stored and delivered to the patient by a simple intravenous infusion as an out-patient. 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.
