Announces second Phase 2 trial of XPro in Mild Cognitive Impairment (MCI) in addition to previously announced Phase 2 trial in mild Alzheimer’s disease (AD)

Cash and cash equivalents of $84.5 million on September 30th

Company to host conference call today, November 3rd, at 4:30pm ET

BOCA RATON, Fla., Nov. 03, 2021 (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 reported its financial results for the third quarter ended September 30, 2021 and provided a business update.

“In the first patient treated in our Phase I study of INKmune™ in high-risk myelodysplastic syndrome, INKmune™ was found to safely produce cancer killing memory-like NK cells while increasing proliferation and persistence of those NK cells. As expected, the memory-like NK cells generated in vivo killed NK-resistant cancer cells in vitro,” stated RJ Tesi, M.D., Chief Executive Officer of INmune Bio. “We now have data from Day 73 post first treatment and over 60% of his peripheral blood NK cells remained activated and highly functional in vitro. We are continuing to screen patients for future enrollment and are in the process of expanding the number of clinical trial sites in the UK and overseas. Our latest drug stability data allows us to extend the shelf-life to over 12 months and consequently we initiated a manufacturing scale up to secure drug supplies as the program expands.”

“In our Phase I trial of XPro in AD, we have shown that XPro decreases biomarkers of neuroinflammation and neurodegeneration while improving biomarkers of CNS repair,” continued Dr. Tesi. “We hope to demonstrate these effects on cognition in the Phase II mild AD trial that is on track to initiate later this year.”

Highlights of the XPro Phase I AD trial and Phase II mild AD trial design will be presented in five presentations at the upcoming Clinical Trials in Alzheimer’s Disease (CTAD) annual meeting in Boston, being held November 9th through 12th.

The Company today announced a second Phase II program in patients with Mild Cognitive Impairment (MCI). This Phase II study will be a three-month, double-blind, randomized, placebo-controlled trial in 90 patients with MCI who express at least one ApoE4 allele. Three patient groups are planned: placebo, 1.0mg/kg and 2.0 mg/kg of XPro once weekly by subcutaneous injection. Patients will be randomized 1:1:1. The treatment duration is three months. Top line results are expected in the first half of 2023. The primary endpoint will examine cognition using the Early AD/MCI Alzheimer's Cognitive Composite (EMACC). Multiple secondary endpoints of cognition (CDR), function (ADCS-ADL MCI, Goal Attainment Scale, NPI) and biology will also be measured, including MRI studies of white matter pathology. Cerebrospinal fluid (CSF) will be obtained to evaluate changes in biomarkers of neuroinflammation and neurodegeneration. All patients that complete the study can enroll in an open-label 12-month extension study.

“Many companies combine MCI and mild AD into one group called Early AD,” said CJ Barnum, Head of Neurosciences at INmune. “However, many of the biomarkers of interest to us differ between MCI and AD patients. This study is not only designed to identify the most appropriate biomarkers for MCI patients, but also to assess XPro’s ability to improve biomarkers of cognition in a way that, if successful, could accelerate our timelines to market.”

The blinded randomized Phase II trial using Quellor to treat respiratory failure in patients with COVID-19 has been closed by the Company due to the rapidly changing COVID-19 therapeutic landscape. Mortality has decreased ten-fold with all patients receiving immunosuppressive corticosteroids. Moreover, most high-risk patients have received vaccinations and oral therapies are soon to be approved. We believe the FDA is no longer offering emergency use authorization (EUA) approvals for this type of therapy after a single Phase II trial. These forces make continued development expensive and difficult. As a result, the Company has decided clinical development for prevention of respiratory failure from COVID-19 is a high risk, low reward program. Considering the very promising results from the Phase I AD trial and the rapidly changing regulatory landscape for Alzheimer’s disease, the Company believes investment in the acceleration of our Phase II mild AD and MCI programs is a better use of the Company’s resources.

Q3 2021 and Recent Corporate Highlights

IINKmune™ Platform Highlights:

  • Announced that the first patient has been treated in the company’s Phase I clinical trial of its Natural Killer (NK) cell priming platform, INKmune™, as a potential treatment for high-risk myelodysplastic syndrome (MDS).
  • Disclosed biomarker data from the first patient in the MDS trial demonstrating that treatment with NK cell priming was well tolerated, induced significant and sustained peripheral NK cell activation and generated memory-like NK cells in vivo without any evidence of cytokine release syndrome.
  • The Company is in the process of opening a second trial site to accelerate recruitment.

XPro Platform Highlights:

  • Announced design of upcoming Phase II Alzheimer’s disease trial. This will be a six-month, blinded, randomized, placebo-controlled trial in 200 patients with mild AD and biomarkers of neuroinflammation. The primary endpoint will examine cognition using the Early AD/MCI Alzheimer's Cognitive Composite (EMACC). Multiple secondary endpoints of cognition will also be measured, including ADAS-COG13 and other endpoints. Data is anticipated in the second half of 2023.
  • Announced design of blinded, randomized Phase II trial of XPro in patients with MCI with top line results expected in the first half of 2023.
  • Disclosed additional data from its successful Phase I study of XPro in Alzheimer’s disease:
    • Patients treated with XPro™ showed a reduction in neurodegeneration as measured by a decrease in CSF phosphor-tau 217 (pT217).
    • Demonstrated that XPro promotes remyelination as measured by increased biomarkers of remyelination in the CSF proteome and decreased biomarkers of demyelination (radial diffusivity) by MRI.
    • XPro increases white matter brain volume after three months in patients with AD .
  • Delivered a poster presentation and XPro was highlighted in a plenary talk at the Alzheimer’s Association International Conference 2021.
  • Will deliver two oral presentations and three posters related to the XPro Phase I trial at CTAD, which runs from November 9th through 12th.

Financial and Corporate Highlights:

  • As of September 30, 2021, the Company had $84.5 million in cash and cash equivalents which includes gross proceeds of $40 million obtained from a registered direct offering and $15 million from the Company’s ATM, sufficient to fund the company at least through mid-2023.
  • Moved corporate headquarters from California to Florida.

Upcoming Milestones:

  • Initiate XPro Phase II program for mild Alzheimer's disease in patients with neuroinflammation by year-end 2021.
  • Initiate Xpro Phase II program for MCI in patients with APOE4 allele by mid-2022.
  • Initiate XPro Phase II program for treatment resistant depression (TRD), funded in part by a $2.9 million NIH grant, by mid-2022.
  • Initiate INKmune™ Phase I program in ovarian cancer in 2H22.

About XPro

XPro is a next-generation inhibitor of tumor necrosis factor (TNF) that is currently in clinical trial and differentiates itself from existing TNF inhibitors in that it neutralizes soluble TNF (sTNF), without affecting trans-membrane TNF (tmTNF) or TNF receptors. XPro could have 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 please 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 akin to treatment with at least three cytokines in combination. INKmune™ is stable at -80oC and is delivered by a simple IV infusion. The INKmune:NK interaction ligates multiple activating and co-stimulatory molecules on the NK cell and enhances its avidity of binding to tumor cells; notably those resistant to normal NK-mediated lysis. Tumor-primed NK (TpNK) cells can lyse a wide variety of NK-resistant tumors including leukemias, lymphomas, myeloma, ovarian cancer, breast cancer.
