Study will be the first-in man trial for INKmune – a novel therapy to prime the patient’s own NK cells to attack their cancer
LA JOLLA, CA, USA I June 11, 2020 IINmune 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, announced that the Medicines and Healthcare products Regulatory Agency (MHRA; the UK equivalent of the FDA) has given approval to initiate a Phase I clinical trial of INKmune, a novel therapy to prime the patient’s own NK cells to attack their cancer, in patients with high-risk Myelodysplastic Syndrome (MDS) (EUDRACT 2019-004820-40). This single center Phase I trial will be the first-in-man study using INKmune. Based on the current environment and timetable of its clinical site, INmune Bio is targeting the study initiation in the 2nd half of this year.
“Patients with MDS are mostly elderly; in this population high-dose chemotherapy or bone marrow transplant are usually too toxic,” said Dr. Marion Wood, consultant hematologist and the medical director for this INKmune program. “With this clinical trial, we hope to show that INKmune will provide an effective and better tolerated therapeutic option for those patients who are poorly served by current therapies.” Patients with high-risk MDS will be enrolled to receive at least 3 doses of INKmune therapy via intravenous infusion, without the need for any type of conditioning therapy or pretreatment. The Phase I trial, called Laurel, will include at least 9 patients enrolled at a single center in the UK and has the capacity for an extension cohort.
“Recent research has shown that MDS patients who survive beyond two years are those with good NK cell activity (Tsirogianni et al 2019). INKmune has been shown to boost the function of NK cells from MDS patients in laboratory experiments. We will target those patients whose NK cells demonstrate a response to INKmune in the laboratory. This is part of our precision approach to immunotherapy,” said Dr. Mark Lowdell, CSO of INmune Bio and discoverer of the science behind INKmune. “We are excited to be able to test it as a treatment in this group of patients facing an unmet therapeutic need.”
“Professor Lowdell and his team in the UK have worked closely with the MHRA to get this trial through regulatory approval, despite the challenges of the COVID-19 pandemic,” said RJ Tesi MD, CEO of INmune. “The INKmune program is the second oncology platform entering the clinic for INmune Bio.”
About INKmune
INKmune is a suspension of replication incompetent tumor cells from our proprietary tumor cell line, INB16; cryopreserved and shipped to the clinical site for local storage at -70oC. INKmune is delivered intravenously and binds to resting NK cells where it provides critical activating signals to initiate NK killing of tumor cells which are resistant to chemotherapy. NK cells activated by INKmune are able to activate other resting NK cells and thus magnify the effect. INKmune-primed NK cells have been shown to kill multiple tumor types including MDS, leukemias, myeloma, breast cancer and ovarian cancer cells in vitro and in vivo (North et al 2007, Sabry et al 2011, Kottaridis et al 2015).

About high-risk MDS
Myelodysplastic syndrome (MDS) describes a range of blood malignancies characterised by anemias, clotting disorders and increased risk of infection all of which often result in death. In the group of MDS patients in this trial there is a high risk of progression to leukemia with rapidly fatal outcome. MDS is predominantly a disease of the elderly with the median age at diagnosis in the UK and USA of 76 years and is incurable in more than 90% of patients; over half of whom will die within 2 years of diagnosis. NK cell activity in these patients is predictive of overall survival beyond two years (Tsirogianni et al 2019).
About INmune Bio, Inc.
INmune Bio, Inc. is a publicly traded (NASDAQ: INMB), clinical-stage biotechnology company focused on developing treatments that target the innate immune system to fight disease. INmune Bio has two product platforms. The DN-TNF product platform utilizes dominant-negative technology to selectively neutralize soluble TNF, a key driver of innate immune dysfunction and mechanistic target of many diseases. DN-TNF is currently being developed for COVID-19 complications (Quellor™), cancer (INB03™), Alzheimer’s (XPro595), and NASH (LIVNate™). The Natural Killer Cell Priming Platform includes INKmune™ aimed at priming the patient’s NK cells to eliminate minimal residual disease in patients with cancer.
