"We believe this IND highlights the potential for INKmune, our natural killer cell targeting immunotherapy, to treat solid tumors," said RJ Tesi M.D., CEO of INmune Bio. "We believe INKmune provides a new treatment option that may allow men with mCRPC to safely avoid cytotoxic chemotherapy and potentially live longer."

The trial is expected to take place in four or more medical centers in the U.S and will enroll approximately 30 patients in a flexible Bayesian design. Matt Rettig MD, Professor of Medicine and Urology, Medical Director of the Prostate Cancer Program at the David Geffen School of Medicine at UCLA and member of the Jonsson Comprehensive Cancer, will be Principal Investigator of the INKmune mCRPC trial. The goal of the trial is to define the safety of INKmune and demonstrate the ability of INKmune-primed NK cells to attack prostate cancer. The results should allow us to choose the best dose of INKmune to move into a blinded randomized trial. Given the novel nature of the treatment, the Company expects a period of consultation with the FDA prior to initiating the planned trial.

"NK cells are often seen in prostate tumor biopsies, but in many cases the cancer cells appear to be resistant to NK killing," said Mark Lowdell Ph.D., CSO of INmune Bio and inventor of the INKmune technology. "The Company believes that INKmune can convert the patient’s own NK cells into cancer killing memory-like NK (mlNK) cells that can survive in the hostile immunosuppressive and hypoxic tumor microenvironment (TME) that as we have shown in vitro, can kill NK-resistant prostate cancer cells."

The 6-month trial will test three doses of INKmune. The therapeutic potential of INKmune in mCRPC will be tested in two ways. First, the immunologic effects of INKmune therapy will be measured by the ability of INKmune to convert the patient’s resting NK cells into cancer killing memory-like NK cells, the ability of those cells to kill a tumor target (RAJI cell line) in vitro and the persistence of that response after treatment. Second, the tumor response to INKmune therapy will be measured using traditional biomarkers of prostate cancer response – progression free survival, changes in blood PSA level and imaging studies (bone and CT scan). Novel biomarkers of tumor response, change in PMSA PET scan and circulating tumor DNA, will also be studied.

Currently, in INmune’s ongoing Laurel INKmune trial, the Company’s MDS/AML INKmune Phase 1 program, the latest patient treated at the Royal Hallamshire Hospital at Sheffield University Medical School finished INKmune treatment without side effects. Initial biomarker data from this patient show, as in previous patients, that she has developed tumor killing memory-like NK cells in her peripheral blood one week after the first dose. Analysis of her later blood samples is underway. The clinical sites continue to review patients for treatment in the Laurel trial. An additional patient will be eligible for treatment in three weeks.

About INKmune

INKmune is an NK cell targeted therapy that is not an NK cell per se but a pharmaceutical-grade, replication-incompetent human tumor cell line which conjugates to resting NK cells in the patient and delivers multiple, essential priming signals, akin to treatment with at least three cytokines in combination; it is a pseudokine. These INKmune-generated tumor-primed NK (TpNK) cells can lyse a wide variety of NK-resistant tumors including leukemias, lymphomas, myeloma and solid tumors including prostate, renal cell, ovarian, nasopharyngeal, lung and breast cancer. INKmune therapy does not require any type of conditioning, pre-medication or cytokine support.

"Enveric is a transformed company; 2022 was a year of considerable accomplishments, and we are now poised for an active, productive and exciting 2023 as we strive to bring a new approach to solving the mental health challenges that face our society," said Joseph Tucker, Ph.D., Director and CEO of Enveric. "In early 2023, we announced the establishment of our Australia-based subsidiary, Enveric Therapeutics Pty. Ltd, and we are rapidly preparing to initiate the planned Phase 1 trial of EB-373. Additionally, we are pleased to be working with Avance Clinical and are eager to benefit from the CRO’s proven expertise and experience managing early-stage clinical programs in Australia."

Dr. Tucker continued: "Conducting the initial development of EB-373 in Australia enables us to leverage key clinical, regulatory and financial opportunities that the Australian government and the Therapeutic Goods Administration (TGA) have implemented to empower biotechnology companies to execute robust yet highly efficient clinical studies, particularly those advancing psychedelic-derived compounds. We now look forward to expeditiously advancing the Phase 1 clinical trial of EB-373 towards a potential topline data readout by early 2024. Our Australian subsidiary also gives Enveric an operational foothold in Australia, which we see as an ideal location to advance the development of additional future pipeline candidates generated from our EVM201 and EVM301 Series."

Dr. Tucker concluded: "2023 will be a year of substantial progress for Enveric, with acceleration of the pipeline milestones to enable us to rapidly grow into a leading, innovative CNS company. Mental health treatments have seen little innovation for decades; stigmatization has abetted a global epidemic in depression and anxiety, which continued to worsen as a result of the COVID-19 pandemic. At Enveric, we believe it’s time for bold innovation and investment to conquer the monumental challenge of tackling mental health disorders."

FOURTH QUARTER AND RECENT PROGRAM UPDATES

A Pipeline Targeting Unmet Needs in Mental Health

● EB-373 nominated as lead development candidate from EVM201 Series targeting the treatment of anxiety disorders
● Phase 1 clinical trial for EB-373 planned to initiate in the fourth quarter of 2023. The trial will be conducted in Australia via Enveric’s newly established subsidiary, Enveric Therapeutics.
○ Avance Clinical identified as CRO to conduct Phase 1 trial

● Enveric continues to advance its EVM301 Series targeting mood, anxiety and addiction disorders with unmet needs.
○ Enveric expects to identify optimal molecular candidates to advance into in vitro and in vivo testing by the third quarter of 2023

Dr. Tucker explained: "With EVM201 Series, we are seeking to address a major gap in innovation with rationally designed, next generation molecules that are prodrugs of the active psychedelic metabolite, psilocin. Through our advanced discovery platform, we’ve been able to design products with altered metabolic and pharmacokinetic properties with the goal of achieving improved risk/benefit profiles. Meanwhile, our EVM301 Series aims at minimizing or eliminating the hallucinatory effect, to enable administration without the compulsory presence of a healthcare professional to observe dosing. We believe this could offer a significant commercial opportunity, as current treatment standards with psychedelics necessitate costly, prolonged sessions with health care providers in attendance."

Positioned Financially and Operationally to be a Leading Developer of Novel Small-Molecule Therapeutics for the Treatment of Anxiety, Depression and Addiction Disorders

● Raised approximately $10 million in gross proceeds via public offering in February 2022
● An additional $8 million gross aggregate proceeds raised with registered direct and private placement offerings, which closed July 2022
● Anticipated spin-off of Akos Biosciences, Inc. (formerly Acanna Therapeutics, Inc.) announced
● Kevin Coveney named as Chief Financial Officer and Lynn Gallant as Vice President, Clinical Operations

Dr. Tucker commented: "The aggressive pace of pipeline developments that we expect in 2023 has been made possible by the execution of several key structural and business development transactions in 2022. This includes our February 2022 public offering, the planned spin-off of our cannabinoid clinical development pipeline assets, which we announced in May, and our registered direct and private placement offerings, which closed July 26, 2022."

"We are excited to explore the potential of Allocetra in combination with tislelizumab, a potentially differentiated PD-1 inhibitor," said Shai Novik, Executive Chairman of Enlivex. "We look forward to integrating tislelizumab into our ongoing Phase I/II clinical trial."

"Combinatorial approaches for fighting difficult-to-treat cancers historically have proven to be important in the delivery of better treatments to patients", said Oren Hershkovitz, Ph.D., CEO of Enlivex. "We believe that the preclinical data observed to date for Allocetra, with its unique macrophage-modulation properties, and immune checkpoints, support the evaluation of the combination for the treatment of patients with the tislelizumab-Allocetra combinations."

Under the terms of the clinical collaboration agreement, Enlivex has agreed to amend its ongoing Phase I/II trial in patients with advanced-stage solid tumors to include evaluation of Allocetra in combination with tislelizumab. The Phase I/II trial is a multicenter, open-label, dose escalation trial that is expected to enroll up to 48 patients with advanced solid tumors across two trial stages. Stage 1 of the trial will examine escalating doses of Allocetra monotherapy administered intravenously (IV) or intraperitoneally (IP) once a week for three consecutive weeks. Stage 2 will evaluate escalating doses of Allocetra administered IV or IP and combined with anti-PD1 therapy. BeiGene will provide the clinical supply of tislelizumab for the trial.

ABOUT TISLELIZUMAB

Tislelizumab (BGB-A317) is a humanized IgG4 anti–PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.

ABOUT ALLOCETRA

Allocetra is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, Allocetra has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as "unmet medical needs", as a stand-alone therapy or in combination with leading therapeutic agents.
