Immune-Onc Therapeutics Makes Two Presentations of IO-108, a Novel Clinical-Stage Myeloid Checkpoint Inhibitor Targeting LILRB2 (ILT4), at the AACR 2022 Annual Meeting

IO-108 promotes innate and adaptive anti-cancer immunity in preclinical models, and it is well-tolerated to date in the ongoing Phase 1 study for the treatment of solid tumors

PALO ALTO, CA, April 8, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced two poster presentations on its clinical stage program IO-108, a novel myeloid checkpoint inhibitor targeting Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4), at the American Association for Cancer Research (AACR) Annual Meeting in New Orleans, Louisiana.

Tumor-associated myeloid cells are immunosuppressive cells that contribute to impaired anti-tumor responses, and limit the efficacy of currently approved cancer immunotherapies, such as T cell checkpoint inhibitors. LILRB2 is a receptor expressed primarily by myeloid cells that has several ligands known to contribute to immune suppression in the tumor microenvironment (TME).

“The pioneering work of our scientific team shows that IO-108 binds to LILRB2 with high affinity and specificity and blocks the interaction of LILRB2 with multiple immunosuppressive ligands. As a result, IO-108 activates and enhances anti-tumor immune responses ex vivo and inhibits the growth of solid tumors in preclinical models,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “Collectively, these studies have enabled a comprehensive clinical biomarker plan and further support the ongoing Phase 1 clinical study of IO-108 as a novel immunotherapy for multiple solid tumor types, including those that are resistant to or relapsed after T cell checkpoint inhibitor treatments.”

Ex vivo studies show that treatment with IO-108 produces pro-inflammatory activity and an enhanced antigen-presenting cell (APC) phenotype to multiple stimuli, including T cell activators, and STING and TLR agonists. As a single agent, IO-108 reverts the anti-inflammatory myeloid cell phenotype caused by “tumor conditioning” to pro-inflammatory phenotype and promotes the differentiation of monocytes and immature dendritic cells into pro-inflammatory dendritic cells, which are critical in generating productive anti-tumor immune responses.

IO-108 enhances the effect of PD-1 blocking antibodies in CD4+ T cell activation by allogeneic macrophages. Moreover, IO-108 monotherapy inhibits the growth of solid tumors in a preclinical model, which is associated with immune cell activation. Importantly, IO-108 presents a favorable pharmacokinetic and safety profile in preclinical models.

In the ongoing Phase 1 study of IO-108 in adult patients with advanced or refractory solid tumors (NCT05054348), IO-108 is studied at 60, 180, 600 and 1800 mg in monotherapy and at 180, 600 and 1800 mg in combination with 200 mg of pembrolizumab, administered intravenously every three weeks. IO-108 has been well-tolerated to date, both as a monotherapy and in combination with pembrolizumab, and dose-limiting toxicity has not been observed so far, at up to 600 mg in monotherapy and 180 mg in combination with pembrolizumab. Enrollment is ongoing with the last patient in expected in the second quarter of 2022.

Details of Immune-Onc’s AACR 2022 presentations are as follows:

ABOUT LILRB2 (ILT4)

LILRB2, also known as ILT4, is expressed mostly by myeloid cells, including monocytes, macrophages, dendritic cells, and neutrophils. In solid tumors, activation of LILRB2 by its ligands, including HLA-G, ANGPTLs, SEMA4A, and CD1d, induces a tolerogenic phenotype in myeloid cells, thereby promoting poor T cell activation and consequent tumor immune evasion.

Immune-Onc Therapeutics Receives FDA Fast Track Designation for IO-202, the First Anti-LILRB4 Myeloid Checkpoint Inhibitor, for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia (AML)

PALO ALTO, CA, February 17, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for IO-202, a first-in-class myeloid checkpoint inhibitor targeting leukocyte immunoglobulin-like receptor B4 (LILRB4, also known as ILT3) for the treatment of patients with relapsed or refractory acute myeloid leukemia (AML). The Company received Orphan Drug Designation for IO-202 for the treatment of AML in 2020.

“We are pleased that the FDA has granted IO-202 Fast Track designation in recognition of its potential to improve outcomes for people with relapsed or refractory AML,” said Paul Woodard, Ph.D., chief medical officer of Immune-Onc. “We look forward to working closely with the FDA to accelerate the clinical development of IO-202, which is currently being evaluated as a monotherapy and in combination with other agents in a Phase 1 dose escalation and expansion trial in patients with AML with monocytic differentiation and in chronic myelomonocytic leukemia (CMML).”

The FDA’s Fast Track designation is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need to get important new medicines to patients earlier. Drugs that receive Fast Track designation may be eligible for more frequent interactions and written communications with the FDA to discuss the development plan and data collection to support an approval pathway. The designation also supports the eligibility for Accelerated Approval and Priority Review if relevant criteria are met.

ABOUT LILRB4 (also known as ILT3)

LILRB4, also known as ILT3, is an immune inhibitory transmembrane protein found on monocytic myeloid cells, including dendritic cells. LILRB4 inhibits antigen-presenting cell activation, resulting in immune tolerance. LILRB4 is also expressed on certain hematologic cancer cells and monocytic myeloid cells in the solid tumor microenvironment. Immune-Onc and The University of Texas published pioneering research in Nature illuminating the role of LILRB4 in immune suppression and tumor infiltration in AML and presented the rationale for targeting LILRB4 in solid tumors at the AACR Annual Meeting 2021.

ABOUT IO-202

IO-202 is a first-in-class LILRB4 antagonist antibody with broad potential as an immunotherapy in both blood cancers and solid tumors. In hematologic malignancies, preclinical studies showed that IO-202 converts a “don’t kill me” to a “kill me” signal by activating T cell killing and converts a “don’t find me” to a “find me” signal by inhibiting infiltration of blood cancer cells. In solid tumors, preclinical data showed that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in a solid tumor model in vivo.

IO-202 is currently in Phase 1 clinical development for the treatment of AML and CMML. The U.S. Food and Drug Administration granted IO-202 Orphan Drug Designations for treatment of AML in 2020. The company has received IND clearance to evaluate IO-202 in solid tumors in January 2022.

Immune-Onc Therapeutics Announces FDA Clearance of IND Application to Initiate Trial of IO-202, a First-in-Class Myeloid Checkpoint Inhibitor Targeting LILRB4, in Patients with Advanced Solid Tumors

– Multicenter Phase 1 study to evaluate IO-202 as monotherapy and in combination with an anti-PD-1 –

PALO ALTO, CA, January 31, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, today announced that the U.S. Food and Drug Administration (FDA) has cleared the company’s Investigational New Drug (IND) application for IO-202, a first-in-class antibody targeting leukocyte immunoglobulin-like receptor B4 (LILRB4, also known as ILT3), for the treatment of solid tumors.

Myeloid cells are abundant and often immune suppressive in the solid tumor microenvironment. The LILRB4 receptor is expressed on monocytic myeloid cells, including dendritic cells, and contributes to a tolerogenic myeloid cell phenotype, resulting in decreased tumor immune surveillance. In preclinical data presented at the 2021 American Association for Cancer Research (AACR) Annual Meeting, IO-202 was found to enhance dendritic cell function and T cell activation in vitro and promote anti-tumor immunity in a solid tumor model in vivo. These data provided a strong rationale to evaluate the therapeutic potential of IO-202 as a myeloid checkpoint inhibitor in solid tumors.

“The FDA clearance to begin our Phase 1 study for IO-202 in solid tumors is a major milestone for Immune-Onc, which represents the third IND for our pipeline and the second for IO-202,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “We know that high LILRB4 expression on myeloid cells infiltrating solid tumors contributes to tumor immune evasion. IO-202 is a first-in-class myeloid checkpoint inhibitor targeting LILRB4, which may provide therapeutic benefit to multiple solid tumor types where evasion of the immune system allows disease to progress and create resistance to therapy, including to T cell checkpoint inhibitors. We look forward to advancing IO-202 into the clinic to evaluate its potential as a monotherapy and in combination with an anti-PD-1 in patients with solid tumors.”

The Phase 1, multicenter, dose-escalation and dose expansion study will consist of a monotherapy cohort and a combination therapy cohort to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of IO-202 alone and in combination with pembrolizumab, an anti-PD-1 antibody, followed by indication-specific expansion cohorts to be treated with IO-202 in combination with pembrolizumab at the recommended Phase 2 dose. Various biomarkers will be assessed to enable a mechanistic understanding of clinical data and inform future trials. This study may also provide an opportunity to identify preliminary efficacy signals.

Immune-Onc Therapeutics to Present Data Supporting Therapeutic Potential of LAIR1 Antagonist Antibodies at the Society for Immunotherapy of Cancer (SITC) 36th Annual Meeting

– Preclinical data to highlight potential of LAIR1 blockade in reversing T-cell and myeloid immunosuppression mediated by collagen –

PALO ALTO, CA, November 9, 2021 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, today announced that the Company will present a scientific poster at the Society for Immunotherapy of Cancer 36th Annual Meeting (SITC 2021) being held November 10-14, 2021, in Washington, D.C., USA.

The poster will feature key preclinical data demonstrating the therapeutic potential of anti-LAIR1 antagonistic antibodies as immune checkpoint inhibitor therapy for solid tumors. LAIR1 (Leukocyte Associated Immunoglobulin-like Receptor 1) is an immune inhibitory transmembrane glycoprotein expressed on lymphocytes and myeloid cells and is activated by collagen and other ligands. Collagen is highly abundant in the stroma of many solid tumor types and thought to contribute to immune suppression. The data being presented suggest that LAIR1 blockade could potentially reverse collagen-mediated myeloid cell tolerogenic phenotype and T-cell suppression, thereby promoting a pro-inflammatory solid tumor microenvironment.

PALO ALTO, CA, October 13, 2021 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting immunosuppressive myeloid checkpoints, today announced that the first patient has been dosed in the Company’s first-in-human clinical trial of IO-108, a novel antagonist antibody targeting the myeloid checkpoint Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4) for the treatment of solid tumors.

“The first patient dosed in our Phase 1 clinical trial for IO-108 represents a critical milestone in advancing the development and understanding of Immune-Onc’s novel myeloid checkpoint inhibitors targeting the LILRB family of immune inhibitory receptors. We believe our scientific platform holds vast promise and today’s news reflects our commitment to rapidly advancing programs in our portfolio that have the potential to improve outcomes for cancer patients,” said Paul Woodard, MD, chief medical officer of Immune-Onc. “With enrollment now underway, we look forward to reporting top line data next year.”

The Phase 1, multicenter, dose-escalation study will consist of a monotherapy cohort and a combination therapy cohort to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of IO-108 alone and in combination with pembrolizumab, an anti-PD-1 antibody. Biomarkers will be assessed to enable a mechanistic understanding of clinical data and inform future trials. This study may also provide an opportunity to identify preliminary efficacy signals. After determination of the recommended Phase 2 dose, Immune-Onc plans to evaluate the efficacy, safety, and tolerability of IO-108 in combination with pembrolizumab and as monotherapy in indication-specific expansion cohorts.

IO-108 binds to LILRB2 with high affinity and specificity and blocks the interaction of LILRB2 with multiple ligands that are involved in cancer-associated immune suppression including HLA-G, ANGPTLs, SEMA4A, and CD1d. In preclinical studies, treatment of various primary human immune cell systems containing myeloid cells with IO-108 results in enhanced pro-inflammatory responses to multiple stimuli that are relevant to anti-tumor immunity. As a single agent, IO-108 reverses the anti-inflammatory myeloid cell phenotype that results from “tumor conditioning” and promotes the differentiation of monocytes into pro-inflammatory dendritic cells. Moreover, IO-108 potentiates the effect of PD-1 blocking antibodies on CD4+ T cell activation in co-cultures with allogeneic macrophages. In mouse models IO-108 inhibits the growth of solid tumors, which is associated with enhanced T cell responses. Together these data demonstrate that IO-108 has the potential to provide additive or synergistic benefit in combination with standard-of-care immunotherapies and/or immunogenic therapies for solid tumors that are both resistant and sensitive to T-cell checkpoint inhibitors.

ABOUT LILRB2 (ILT4)

LILRB2, also known as ILT4, is expressed mostly on myeloid cells, including monocytes, dendritic cells, macrophages, and neutrophils. In solid tumors, interaction of LILRB2 with tumor microenvironment (TME) relevant ligands, including HLA-G, ANGPTLs, SEMA4A, and CD1d, makes myeloid cells pro-tumorigenic (tolerating or promoting tumor growth) and promotes tumor immune evasion.

Immune-Onc Therapeutics Announces First Public Presentation of Data for its Myeloid Checkpoint Inhibitor, IO-202, in Solid Tumors at AACR21

– IO-202, a first-in-class LILRB4 antagonist antibody, activates dendritic cells and inhibits solid tumor growth in preclinical studies –

PALO ALTO, CA, April 10, 2021 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, announced today the first public presentation of preclinical data for its first-in-class myeloid checkpoint inhibitor, IO-202, an LILRB4 antagonist antibody, in solid tumors. The electronic poster will be presented as part of the Immune Checkpoints Session of the American Association for Cancer Research (AACR) Annual Meeting 2021 (#AACR21), taking place virtually April 10-15, 2021.

Myeloid cells are abundant and often immune suppressive in the solid tumor microenvironment (TME). LILRB4 (also known as ILT3) is expressed on monocytic myeloid cells, offering rationale for investigating the potential of IO-202 in solid tumors. IO-202 may be combined with anti-PD-(L)1, other immunotherapies, and/or immunogenic chemotherapy in future investigations of novel treatment approaches for solid tumors.

“It is widely recognized that only a minority of patients achieve a complete or durable response to T cell checkpoint inhibitor therapies. IO-202 is a first-in-class myeloid checkpoint inhibitor targeting LILRB4, a protein that contributes to cancer immune evasion, not only in blood cancers but also in many solid tumor types,” said An Song, Ph.D., chief scientific officer of Immune-Onc. “Today, for the first time, we report preclinical data showing that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in a solid tumor model in vivo. As we move toward the clinic, these data improve our understanding of the role of LILRB4 in the tumor microenvironment and reinforce the therapeutic potential of IO-202 in solid tumors.”

Abstract Number: 1629

ABOUT LILRB4 (also known as ILT3)

LILRB4, also known as ILT3, is an immune inhibitory transmembrane protein found on monocytic myeloid cells, including antigen presenting cells (APCs). LILRB4 inhibits APC activation, resulting in immune tolerance. LILRB4 is also expressed on certain hematologic cancer cells and monocytic myeloid cells in the solid tumor microenvironment. Immune-Onc and The University of Texas published pioneering research in Nature illuminating the role of LILRB4 in immune suppression and tumor infiltration in acute myeloid leukemia (AML).

About IO-202

Immune-Onc’s lead asset, IO-202, is a first-in-class LILRB4 antagonist antibody with broad potential as an immunotherapy in both blood cancers and solid tumors. In hematologic malignancies, preclinical studies showed that IO-202 converts a “don’t kill me” to a “kill me” signal by activating T cell killing and converts a “don’t find me” to a “find me” signal by inhibiting infiltration of blood cancer cells.

In September 2020, Immune-Onc initiated a Phase I trial evaluating IO-202 in AML with monocytic differentiation and in chronic myelomonocytic leukemia (CMML). The U.S. Food and Drug Administration granted IO-202 Orphan Drug Designation for treatment of AML in October 2020.

Immune-Onc Therapeutics Announces Orphan Drug Designation of IO-202 (Anti-LILRB4) for Treatment of AML and Poster Presentation at ASH 2020

– “Trials in Progress” poster presentation at the American Society of Hematology (ASH) Annual Meeting to detail mechanisms of action, preclinical data and trial design –

– IO-202, targeting the immune inhibitory receptor LILRB4 (also known as ILT3), is being evaluated in a Phase I trial for acute myeloid leukemia (AML) and chronic myelomonocytic leukemia (CMML) –

PALO ALTO, CA, November 10, 2020 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation status for its first-in-class antagonist antibody IO-202 for treatment of acute myeloid leukemia (AML). In addition, the company announced acceptance of its “Trials in Progress” poster presentation for IO-202 at the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition. The meeting is taking place virtually December 5-8, 2020.

Orphan Drug Designation qualifies the sponsor for various development incentives of the Orphan Drug Act, including exemption of FDA application fees and tax credits for qualified clinical testing, to advance the evaluation and development of products that demonstrate promise for the diagnosis and treatment of rare diseases or conditions that affect fewer than 200,000 people in the United States. Orphan Drug Designation can also convey seven years of marketing exclusivity for a drug approved to treat an orphan disease in the United States.

“Receiving orphan drug designation for IO-202 in AML is another important milestone for Immune-Onc and underscores the need for effective new treatments for this aggressive and hard-to-treat cancer,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “We are pleased with the progress we are making in advancing IO-202. As outlined in our ASH poster presentation, IO-202 holds promise for AML patients because it demonstrates novel mechanisms of action in overcoming immune suppression. IO-202 is one of several programs in our pipeline that target the LILRB family of immune inhibitory receptors. We are excited to continue our momentum in evaluating IO-202 and Immune-Onc's preclinical candidates in other cancers, including solid tumors, in the near future.”

ASH “Trials in Progress” Poster

Based on highly selective criteria, “Trials in Progress" abstracts are reviewed for the most innovative science. The abstract (#2867), “A First-in-Human (FIH) Phase 1 Study of the Anti-LILRB4 Antibody IO-202 in Relapsed/Refractory (R/R) Myelomonocytic and Monocytic Acute Myeloid Leukemia (AML) and R/R Chronic Myelomonocytic Leukemia (CMML)”, was selected for poster presentation in the 2020 ASH Annual Meeting Program. Lead investigator Courtney D. DiNardo, M.D., MSc, associate professor, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, will share the poster via a brief PowerPoint presentation with accompanying audio.

The poster (Abstract #2867) will be presented at Session: 616. Acute Myeloid Leukemia: Novel Therapy, excluding Transplantation: Poster III, on Monday, December 7, 2020, 7:00 a.m. - 3:30 p.m. Pacific Time.

In addition to the presentation, the abstract was published online in the November supplemental issue of Blood and in the online meeting program on November 5, 2020.

ABOUT LILRB4 (also known as ILT3)

LILRB4, also known as ILT3, is an immune-modulatory transmembrane protein found on antigen presenting cells (APCs). It inhibits APC activation and induces immune tolerance via T-suppressor cells. It is expressed on certain hematologic cancer cells and immune suppressive myeloid cells in the solid tumor microenvironment. Immune-Onc and The University of Texas published pioneering research in Nature illuminating the role of LILRB4 in immune suppression and tumor infiltration in AML.

ABOUT IO-202

IO-202 is a first-in-class monoclonal antibody that antagonizes LILRB4 with high binding affinity and specificity. It has broad potential in both blood cancers and solid tumors. In hematologic malignancies, preclinical studies showed that IO-202 converts a “don’t kill me” to a “kill me” signal by activating T cell killing and converts a “don’t find me” to a “find me” signal by inhibiting infiltration of hematologic cancer cells.

IO-202 is being evaluated in a Phase I trial in two forms of blood cancer, AML and CMML. The U.S. Food and Drug Administration granted IO-202 Orphan Drug Designation status for treatment of AML in October 2020.

In solid tumors, IO-202 has potential to be combined with anti-PD-(L)1, other immunotherapies, and/or immunogenic chemotherapy. The company plans to evaluate IO-202 in solid tumors and in other forms of blood cancer in the near future.

ABOUT AML and CMML

AML, the most common acute leukemia (blood and bone marrow cancer) in adults, is characterized by the proliferation of abnormal myeloblasts (a type of white blood cell) in the bone marrow. Nearly 20,000 new cases are expected in the U.S. in 2020. Despite advances in treatment, less than 30 percent of acute myeloid leukemia patients are alive five years after initial diagnosis.

CMML is a cancer that starts in blood-forming cells in the bone marrow and invades the blood. The condition is rare, with about 1,100 cases in the U.S. each year.

Immune-Onc Therapeutics to Present Preclinical Data for IO-108, a Novel Antagonist Antibody Targeting LILRB2 (ILT4) in Solid Tumors, at SITC 2020

PALO ALTO, CA, November 9, 2020 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage cancer immunotherapy company, will present preclinical data evaluating IO-108, a novel antagonist antibody targeting the myeloid checkpoint Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4) for the treatment of solid tumors, at The Society for Immunotherapy of Cancer (SITC) 35th Anniversary Annual Meeting & Pre-Conference Programs (SITC 2020). The full meeting takes place virtually November 9-14, 2020.

The poster (Abstract #686) titled, “Preclinical Characterization of a Novel Therapeutic Antibody Targeting LILRB2”, will be presented on Thursday, Nov. 12, from 4:50-5:20 p.m. EST and on Saturday, Nov. 14, from 1-1:30 p.m. EST.

“Immune-Onc’s unique scientific insights in myeloid cell checkpoints, with a particular focus on the Leukocyte Immunoglobulin-Like Receptor subfamily B (LILRB), have led to a promising and differentiated immunotherapy pipeline,” said Charlene Liao, Ph.D., co-founder and CEO of Immune-Onc. “The preclinical data to be presented at SITC demonstrate the exciting potential of IO-108, a novel therapeutic agent targeting LILRB2. We look forward to advancing IO-108 into the clinic in 2021 to evaluate its safety and efficacy in patients with solid tumors.”

IO-108 binds to LILRB2 with high affinity and specificity and blocks the interaction of LILRB2 with ligands that are involved in cancer-associated immune suppression including HLA-G, ANGPTLs and SEMA4A. In assays with primary cells, IO-108 enhances pro-inflammatory activation of immune cells and induces differentiation of monocytes into activated dendritic cells. In ex vivo functional studies with samples from solid tumor patients, IO-108 reprograms immune suppressive myeloid cells to a pro-inflammatory phenotype, thereby enhancing T-cell activation. Together these data suggest that IO-108 has potential therapeutic benefit in solid tumors not responsive to T-cell checkpoint inhibitors. The company plans to file an Investigational New Drug (IND) application for IO-108 with the U.S. Food and Drug Administration in Q2 2021.

ABOUT LILRB2 (ILT4)

LILRB2, also known as ILT4, is expressed mostly on myeloid cells, including monocytes, dendritic cells, macrophages, and neutrophils. In solid tumors, interaction of LILRB2 with tumor microenvironment (TME) relevant ligands, including HLA-G, ANGPTLs, and SEMA4A, makes myeloid cells pro-tumorigenic (tolerating or promoting tumor growth) and promotes tumor immune evasion.

Immune-Onc Therapeutics Announces First Patient Dosed in Phase I Trial Evaluating IO-202, a First-In-Class Antibody for the Treatment of Acute Myeloid Leukemia

– First-In-Human Trial Targeting the Immune Inhibitory Receptor, LILRB4 –

– Preclinical Data Show LILRB4 Plays a Role in Immune Suppression and Tumor Infiltration –

PALO ALTO, CA, September 16, 2020 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a cancer immunotherapy company focused on developing first-in-class biotherapeutics that target novel immunosuppressive myeloid checkpoints announced today that the first patient has been dosed in its Phase I study evaluating IO-202, a first-in-class antibody targeting leukocyte immunoglobulin-like receptor B4 (LILRB4, also known as ILT3). The Phase I dose escalation and expansion trial will evaluate IO-202 in patients with acute myeloid leukemia (AML) with monocytic differentiation and in chronic myelomonocytic leukemia (CMML).

IO-202 is the first T-cell activator for AML. In preclinical studies, IO-202 has shown evidence of activating T cell cytotoxicity against leukemia cells and blocking leukemia infiltration.

“I am thrilled that we’ve met this important goal and with the support of our investigators are one step closer to bringing a new approach to the treatment of blood cancers, AML and CMML,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “As we learn more about myeloid cell biology and its role in cancer, we see opportunities to explore the potential of IO-202 and other novel antibodies in other types of cancer, including solid tumors, in the near future.”

The dose-escalation phase of the trial will identify the optimal dose of IO-202. Once the recommended dose of IO-202 is selected, the trial will enroll patients in an expansion cohort to evaluate IO-202 as monotherapy. There is potential to evaluate IO-202 in combination with other agents with a protocol amendment. Biomarkers will be assessed to enable a mechanistic understanding of clinical data and inform future trials. In August, the company announced it had been awarded a Small Business Innovation Research (SBIR) grant from the National Cancer Institute (NCI) of the National Institutes of Health (NIH) to support development of IO-202.
