Immune-Onc Therapeutics Announces Positive Results from Phase 1 Dose Escalation Study of IO-108 in Advanced Solid Tumors Published in the Journal for ImmunoTherapy of Cancer
- Data demonstrates potential for IO-108 to enhance immune activation and overcome resistance in advanced solid tumors as a monotherapy and in combination with pembrolizumab -
PALO ALTO, CA, November 21, 2024 -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private clinical-stage biopharmaceutical company advancing novel therapies in immunology and oncology by targeting myeloid cell inhibitory receptors, today announced the publication of Phase 1 dose-escalation study results of IO-108, its first-in-class antibody targeting LILRB2 (also known as ILT4), in the Journal for ImmunoTherapy of Cancer (JITC), the peer-reviewed, online journal of the Society for Immunotherapy of Cancer (SITC).
The paper, entitled “Phase 1 Dose Escalation Study of IO-108, an Anti-LILRB2 Antibody, in Patients with Advanced Solid Tumors,” details the safety, tolerability, preliminary efficacy, pharmacokinetics, immunogenicity, and pharmacodynamic biomarker results from 25 patients with advanced solid tumors enrolled in a first-in-human study of IO-108 as a monotherapy and in combination with pembrolizumab, an anti-PD-1 antibody.
In the IO-108 monotherapy cohort, the overall response rate was 9%, with one patient achieving a durable complete response (CR) for over two years. The CR was observed in a patient with treatment-refractory Merkel cell carcinoma whose prior treatment included two lines of immunotherapy (pembrolizumab, followed by a combination of nivolumab (anti-PD-1) and ipilimumab (anti-CTLA-4)).
Among 13 efficacy-evaluable patients treated with the combination of IO-108 plus pembrolizumab, 3 patients (2 cholangiocarcinoma and 1 colon cancer, all microsatellite-stable cancer types that typically do not respond to T-cell checkpoint inhibitors) had a partial response (23%).
Biomarker analysis revealed pharmacodynamic changes consistent with increased T-cell infiltration in tumors, indicating an activated tumor microenvironment in patients with clinical benefit in both monotherapy and combination therapy. Results also demonstrated that IO-108 was well-tolerated at all dose levels, with no dose-limiting toxicities observed.
“The durable responses observed in this heavily pretreated patient population underscore the therapeutic potential of IO-108 as both a monotherapy and in combination with T-cell immune checkpoint inhibitors,” said IO-108 Phase 1 investigator and first author of the paper, Matthew H. Taylor, M.D., Earle A. Chiles Research Institute, Providence Cancer Institute, Portland, Oregon. “These findings provide compelling evidence that targeting myeloid-cell immune checkpoint LILRB2 offers a novel and promising approach to cancer treatment.”

“We are very proud of our positive data published in the Journal for ImmunoTherapy of Cancer (JITC),” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “Our data suggest that IO-108 could play a pivotal role as a monotherapy and combination therapy with T-cell immune checkpoint inhibitors and support the broader clinical exploration of IO-108 as a versatile therapeutic option for patients with advanced solid tumors.”
Immune-Onc is advancing the development of IO-108 in a Phase 1b/2 global, randomized study that is part of Roche’s Morpheus-Liver program. The study will evaluate IO-108 in combination with atezolizumab and bevacizumab versus atezolizumab and bevacizumab, the standard of care in patients with locally advanced, metastatic and/or unresectable liver cancer with no prior systemic treatment. The study’s primary endpoint is objective response rate, and key secondary endpoints include progression-free survival and overall survival.
ABOUT IO-108
IO-108 is a fully human IgG4 monoclonal antibody with high affinity and specificity towards the myeloid checkpoint, LILRB2 (also known as ILT4). It blocks the interaction of LILRB2 with multiple ligands involved in cancer-associated immune suppression, including HLA-G, ANGPTLs, SEMA4A and CD1d. Clinical data from the U.S. Phase 1 dose escalation study of IO-108 (NCT05054348) was presented at the 2023 American Association for Cancer Research annual meeting and demonstrated a favorable safety profile and encouraging clinical benefit utilizing IO-108 as a monotherapy and in combination with anti-PD-1 across multiple tumor types.
IO-108 is being studied in several expansion cohorts in adult cancer patients as a monotherapy and in combination with anti-PD-1 antibodies (pembrolizumab, cemiplimab or tislelizumab). A global, randomized Phase 1b/2 study is underway to evaluate IO-108 in combination with atezolizumab and bevacizumab as a potential first-line therapy for hepatocellular carcinoma (HCC).

ABOUT CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML)
CMML is a rare form of blood cancer, occurring in 4 of every 1,000,000 people in the United States each year,2 or about 1,100 annual cases.3 CMML is characterized by a high monocyte count (>1x109/L peripheral monocytes with monocytes ≥ 10% of white blood count) and dysplastic features in the bone marrow.1 Current FDA-approved therapies for CMML are all hypomethylating agents, including azacitidine, only achieving a 7-17% complete response rate.2
ABOUT LILRB4 (also known as ILT3)
LILRB4, also known as ILT3, is an immune-modulatory transmembrane protein found on monocytes and monocyte-derived cells. LILRB4 is expressed on certain hematologic cancer cells, such as myelomonocytic leukemia blasts, and on certain pathogenic cells involved in autoimmunity and inflammatory processes.
ABOUT IO-202
IO-202 is a first-in-class IgG1 antibody with specific, high-affinity binding to LILRB4 and depletes LILRB4 positive cells via antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. As such, IO-202 is a targeted therapy with broad potential in blood cancers and autoimmune and inflammatory diseases.
IO-202 has completed the dose escalation part of the first-in-human, multicenter, open-label Phase 1 study in the U.S., and the data was presented at the European Hematology Association (EHA) Congress in 2023. This Phase 1 trial has advanced to the dose expansion stage to evaluate IO-202 in combination with azacitidine (NCT04372433) in patients with newly diagnosed chronic myelomonocytic leukemia (CMML) who have not received any hypomethylating agents (HMA).
The U.S. Food and Drug Administration granted IO-202 Fast Track Designations for the treatment of patients with relapsed or refractory acute myeloid leukemia (AML) and relapsed or refractory CMML, respectively. The FDA has also granted IO-202 Orphan Drug Designations for the treatment of AML and CMML, respectively.

Immune-Onc Therapeutics to Present Additional Positive Interim Data From IO-202 Phase 1b Expansion Cohort in Patients with Chronic Myelomonocytic Leukemia (CMML) at the 2024 EHA Annual Congress
- Strength of clinical data presented to date support a registrational CMML study -
PALO ALTO, CA, June 14, 2024 -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage biopharmaceutical company advancing novel therapies in immunology and oncology by targeting myeloid cell inhibitory receptors, today announced the company will present additional positive interim Phase 1b expansion cohort data for IO-202 in patients with chronic myelomonocytic leukemia (CMML) at the 2024 European Hematology Association (EHA) Annual Meeting held virtually and in Madrid, Spain, June 13 – 16.
CMML is a rare hematologic malignancy with poor survival outcomes, incurable with conventional therapy, and has no effective standard of care. Currently, hypomethylating agents (HMA), including azacitidine (AZA), are the only FDA-approved treatment option for CMML with only a 7-17% complete remission (CR) rate.
Promising early-cycle responses, including a 53.8% (7 out of 13) CR rate (4 CR, 1 CR equivalent, and 2 CR bilineage), based on International Working Group 2023 response criteria, were observed in CMML patients treated with IO-202 in combination with AZA, with CRs lasting to ten months and ongoing. The Phase 1b interim data continue to demonstrate that IO-202 is well tolerated.
“Chronic myelomonocytic leukemia remains a disease with poor prognosis and risk of progression into acute myeloid leukemia (AML), resulting in a critical need for innovative medicines,” said IO-202 Phase 1b investigator Courtney DiNardo, M.D., MSCE, professor, Department of Leukemia, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center, Houston, TX. “We are encouraged by Phase 1b trial data showing early and sustained complete remissions among CMML patients, regardless of their prognosis or mutation status. This supports the potential of IO-202 in combination with azacitidine as a frontline therapy for CMML patients, and we are pleased to share these data with the medical community at EHA this year.”
“IO-202 has favorable tolerability, a well-understood mechanism of action, and a consistent efficacy response that supports further study as a treatment option in both AML and CMML patients,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “We look forward to continued collaborations with our investigators and the FDA to plan and conduct our registrational study in frontline CMML patients.”

Phase 1 study of IO-202 in combination with azacitidine currently enrolling newly diagnosed CMML patients
PALO ALTO, CA, February 21, 2024 -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a clinical-stage biopharmaceutical company advancing novel therapies in immunology and oncology by targeting myeloid cell inhibitory receptors, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for IO-202 for the treatment of chronic myelomonocytic leukemia (CMML). IO-202 received Fast Track Designation for treatment of relapsed or refractory CMML in 2023. In addition, Fast Track and Orphan Drug Designations for IO-202 were granted by the FDA for the treatment of acute myeloid leukemia (AML) in 2022 and 2020, respectively.
IO-202 is a first-in-class antagonist antibody with specific, high affinity binding to Leukocyte Immunoglobulin-Like Receptor subfamily B4 (LILRB4) and serves as a targeted therapy with broad potential in blood cancers, autoimmune and inflammatory diseases. IO-202 in combination with azacitidine (AZA) is currently in a Phase 1 dose expansion clinical trial (NCT04372433), enrolling newly diagnosed patients with CMML who have not received any hypomethylating agents (HMA). A dose escalation trial of IO-202 has been completed, showing clinical efficacy in relapsed or refractory AML and CMML, either as a monotherapy or in combination with AZA. IO-202 has been shown to be well tolerated in all patients treated to date.
“Although current therapeutic options for CMML can improve a patient’s quality of life, there is a high unmet need for effective disease-modifying approaches that are potentially curative,” said Charlene Liao Ph.D., chief executive officer and board chair of Immune-Onc. “We are very proud that the FDA has granted IO-202 Orphan Drug Designation for the treatment of CMML. We look forward to continued collaborations with our investigators and the FDA as we work to bring this potentially important therapy to patients with hard-to-treat blood cancers.”
The FDA grants Orphan Drug Designation to medicines and potential new medicines intended for the treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the U.S. 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, and conveys seven years of marketing exclusivity for a drug approved to treat an orphan disease in the United States.
ABOUT CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML)
CMML is a rare form of blood cancer, occurring in 4 of every 1,000,000 people in the United States each year, or about 1,100 annual cases1. CMML is characterized by the presence of a high monocyte count (>1x109/L peripheral monocytes with monocytes ≥ 10% of white blood count) along with dysplastic features in the bone marrow2. Current FDA approved therapies for CMML are all hypomethylation agents, including azacitidine, that attempt to control CMML without enhancement to overall survival.
ABOUT LILRB4 (also known as ILT3)
LILRB4, also known as ILT3, is an immune-modulatory transmembrane protein found on monocytes and monocyte-derived cells. LILRB4 is expressed on certain hematologic cancer cells, such as myelomonocytic leukemia blasts, and on certain pathogenic cells involved in autoimmunity and inflammatory processes.
ABOUT IO-202
IO-202 is a first-in-class antagonist antibody with specific, high affinity binding to LILRB4. IO-202 is a humanized IgG1 antibody with Fc effector function to kill LILRB4hi cells via antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). As such, IO-202 is a targeted therapy with broad potential in both blood cancers and autoimmune and inflammatory diseases.
IO-202 has completed the dose escalation part of the first-in-human, multicenter, open-label Phase 1 study in the U.S., and the data was presented at the European Hematology Association (EHA) Congress in 2023. This Phase 1 trial has advanced to the dose expansion stage to evaluate IO-202 in combination with azacitidine (NCT04372433) in patients with newly diagnosed chronic myelomonocytic leukemia (CMML) who have not received any hypomethylating agents (HMA).
The U.S. Food and Drug Administration granted IO-202 Fast Track Designations for treatment for the treatment of patients with relapsed or refractory acute myeloid leukemia (AML) and for the treatment of patients with relapsed or refractory chronic myelomonocytic leukemia (CMML). The FDA has also granted Orphan Drug Designations to IO-202 for the treatment of AML and for the treatment of CMML.

PALO ALTO, CA, February 20, 2024 – Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage biopharmaceutical company dedicated to advancing novel therapies in immunology and oncology by targeting myeloid cell inhibitory receptors, today announced a Phase 1b/2 clinical trial collaboration with Roche to evaluate Immune-Onc’s IO-108, a first-in-class antibody targeting LILRB2 (also known as ILT4), in combination with Roche’s atezolizumab and bevacizumab for the first-line treatment of patients with locally advanced or metastatic and/or unresectable hepatocellular carcinoma (HCC). Atezolizumab and bevacizumab is the first cancer immunotherapy combination regimen approved by the U.S. Food and Drug Administration for this setting and is the recommended standard of care by the National Comprehensive Cancer Network.
“We are excited to work with Roche to accelerate the development of IO-108,” said Charlene Liao, Ph.D., chief executive officer and board chair of Immune-Onc. “IO-108 has demonstrated clinical activity and an acceptable safety profile across multiple solid tumors as monotherapy and in combination with T cell checkpoint inhibitors. The collaboration marks a significant milestone in establishing IO-108 as the preferred myeloid checkpoint inhibitor for combination with standard of care immunotherapy regimens in solid tumors.”
Under the collaboration, Roche will sponsor and conduct the global, randomized Phase 1b/2 trial to evaluate the safety, efficacy and pharmacodynamics of IO-108 in combination with atezolizumab and bevacizumab compared to atezolizumab and bevacizumab, the standard of care treatment regimen for advanced liver cancer.
ABOUT THE RANDOMIZED CLINICAL TRIAL
The Phase 1b/2 global, randomized HCC study is part of Roche’s Morpheus-Liver program. It will evaluate IO-108 in combination with atezolizumab and bevacizumab (“triplet”) versus atezolizumab and bevacizumab (“doublet”), the standard of care in patients with locally advanced or metastatic and/or unresectable HCC with no prior systemic treatment.
Initially, 40 patients will be enrolled across 25 sites worldwide in the IO-108 triplet combination, which will be compared to an active control arm of the atezolizumab and bevacizumab doublet combination. The study’s primary endpoint is objective response rate, and key secondary endpoints include progression-free survival and overall survival.
Under the terms of the clinical collaboration agreement, Roche will manage the study operations, and Immune-Onc will supply IO-108 to support the trial while retaining global rights to IO-108.

ABOUT HEPATOCELLULAR CARCINOMA
According to the American Cancer Society1, more than 800,000 people are diagnosed with liver cancer each year worldwide. It is also one of the leading causes of cancer deaths worldwide, accounting for more than 700,000 deaths each year. The number of people diagnosed is predicted to rise, with the incidence of liver cancer increasing by 55.0% and the number of deaths increasing by 56.4% between 2020 and 20402. Hepatocellular carcinoma is the most common form of liver cancer in the United States, making up almost 90% of cases3. Nine out of ten cases of HCC are caused by chronic liver disease, which includes chronic hepatitis B and C infection, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related liver disease (ALD), and cirrhosis resulting from these conditions4.
ABOUT IO-108
IO-108 is a fully human IgG4 monoclonal antibody with high affinity and specificity towards the myeloid checkpoint, LILRB2 (also known as ILT4). It blocks the interaction of LILRB2 with multiple ligands involved in cancer-associated immune suppression, including HLA-G, ANGPTLs, SEMA4A, and CD1d. Clinical data from the U.S. Phase 1 dose escalation study of IO-108 (NCT05054348) was presented at the 2023 American Association for Cancer Research annual meeting and demonstrated a favorable safety profile and encouraging clinical benefit utilizing IO-108 as a monotherapy and in combination with anti-PD-1 across multiple tumor types. IO-108 is being studied in several expansion cohorts in adult cancer patients as a monotherapy and in combination with anti-PD-1 antibodies (pembrolizumab, cemiplimab or tislelizumab). A global, randomized Phase 1b/2 study is underway to evaluate IO-108 in combination with atezolizumab and bevacizumab as a potential first-line therapy for hepatocellular carcinoma (HCC).

Immune-Onc Therapeutics Presents IO-202 Phase 1 Data in Patients with Relapsed or Refractory AML and CMML at the EHA Annual Meeting 2023
- IO-202 (anti-LILRB4) is well tolerated, with encouraging clinical responses in both monotherapy and combination therapy -
- FDA granted Fast Track designation to IO-202 for the treatment of relapsed or refractory CMML -
PALO ALTO, CA, June 7, 2023 – Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage oncology company dedicated to the discovery and development of novel biotherapeutics by targeting inhibitory receptors on myeloid cells, today announced Phase 1 data for IO-202, a first-in-class humanized IgG1 monoclonal antibody targeting Leukocyte Immunoglobulin-Like Receptor B4 (LILRB4, also known as ILT3). Data from the dose escalation part of the Phase 1 study evaluating patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) and chronic myelomonocytic Leukemia (CMML) will be presented during a poster session at the European Hematology Association (EHA) Annual Meeting in Frankfurt, Germany on June 9, 2023.
“AML is the most common form of acute leukemia in adults in the U.S. and is characterized by high rates of relapsed and refractory disease. Monocytic AML is especially in need of break-through medicine as it is often resistant to standard-of-care treatment. CMML is a rare leukemia overlap syndrome characterized by the accumulation of monocytes in the blood and bone marrow, with both myeloproliferative and myelodysplastic features,” said IO-202 Phase 1 investigator, Courtney DiNardo, M.D., MSCE, associate professor, Department of Leukemia, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center, Houston, TX. “These results, showing strong safety and promising clinical activity as both monotherapy and in combination with a standard-of-care chemotherapy for monocytic AML and CMML, suggest that LILRB4 may be an important therapeutic target for hard-to-treat blood cancers.”
“We are very encouraged with the efficacy data of IO-202 as a single agent and in combination with azacitidine in heavily pre-treated patients with R/R AML and CMML,” said Paul Woodard, MD, chief medical officer of Immune-Onc. “Based on the data, we have developed a patient enrichment strategy for the ongoing dose expansion phase of the study to select AML patients who would most likely respond to IO-202. We are also pleased to receive the FDA Fast Track designation for IO-202 for the treatment of R/R CMML, which follows the R/R AML Fast Track designation received in 2022. We look forward to working closely with the FDA and trial investigators to accelerate the clinical development of IO-202 in hematologic malignancies.”
The Phase 1 multicenter, open-label, dose escalation study of IO-202 assessed the safety and tolerability of IO-202 in successive cohorts of patients with R/R AML with monocytic differentiation and R/R CMML as its primary objective. Secondary and exploratory objectives included pharmacokinetics, immunogenicity, pharmacodynamic (PD) biomarker effects, and clinical response rate of IO-202 as a monotherapy and in combination with azacitidine (AZA).
Treatment with IO-202 was well tolerated. There were no dose-limiting toxicities observed and a maximum tolerated dose was not reached. In the monotherapy treatment cohorts, one CMML patient demonstrated clinical benefit for more than one year and one AML patient achieved a partial response (PR). In combination therapy cohorts, Complete Remission (CR) has been achieved and is on-going for over 10 months in an AML patient with high LILRB4 expression. Additionally, 3 out of 5 CMML patients achieved clinical benefit including Optimal Marrow Response.
Based on the promising results of the dose escalation part of the study and utilizing a biomarker driven patient selection strategy, the Company has opened dose expansion cohorts to enroll AML patients with monocytic differentiations and high LILRB4, and CMML patients (IO-202-CL-001; NCT04372433).
Poster presentation details are as follows:

ABOUT IO-202
IO-202 is a humanized IgG1 monoclonal antibody (mAb) with high affinity and specificity towards LILRB4 (also known as ILT3). It blocks the interaction of LILRB4 with multiple ligands, including ApoE and Fibronectin, and has broad potential in blood cancers and solid tumors. In hematologic malignancies, preclinical studies showed that IO-202 causes depletion of cells expressing high LILRB4 through antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP), 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 the context of solid tumors, preclinical data presented at the 2021 American Association for Cancer Research annual meeting demonstrate that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in an immune competent model in vivo.
IO-202 has two ongoing clinical studies in the U.S.: The Phase 1 trial is currently enrolling expansion cohorts of patients with monocytic (LILRB4 high) acute myeloid leukemia (AML) or chronic myelomonocytic leukemia (CMML) in combination with standard-of-care agents such as azacitidine +/- venetoclax (NCT04372433). The U.S. Food and Drug Administration granted IO-202 Orphan Drug designation for treatment of AML in 2020, as well as Fast Track designations for relapsed or refractory AML in 2022 and relapsed or refractory CMML in 2023. The second Phase 1 trial of IO-202 is currently enrolling patients with advanced solid tumors to evaluate IO-202 as a monotherapy and in combination with an anti-PD-1 (NCT05309187).

Immune-Onc Therapeutics to Present Encouraging Phase 1 Data for IO-108 at AACR Annual Meeting 2023
- Phase 1 data show encouraging clinical benefit for IO-108 as a monotherapy and when combined with pembrolizumab, suggesting potential to overcome resistance to T-cell checkpoint inhibitors -
- Preclinical data for IO-312, a novel bispecific antibody targeting LILRB4 (ILT3) and CD3 (LILRB4 x CD3) will be presented as a late-breaking poster at AACR 2023 -
PALO ALTO, CA, April 14, 2023 – Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced encouraging Phase 1 dose escalation data for IO-108, a novel myeloid checkpoint inhibitor targeting Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4). The data will be presented in an oral session at the American Association for Cancer Research (AACR) Annual Meeting in Orlando, Florida, April 18. Preclinical data for IO-312, a novel bispecific antibody targeting LILRB4 (ILT3) and CD3 (LILRB4 x CD3) will also be presented on April 18 as a late-breaking poster at AACR 2023.
“We are very encouraged to see promising signs of clinical activity across multiple solid tumor types and a favorable safety profile with our first-in-class myeloid checkpoint inhibitor, IO-108,” said Charlene Liao, Ph.D., chief executive officer and board chair of Immune-Onc. “Our data demonstrates the utility of IO-108 as a new therapeutic modality to address key unmet needs for patients with solid tumors that do not respond to, develop resistance to, or relapse following, treatment with T cell checkpoint inhibitors.”
The Phase 1 dose escalation study of IO-108 is intended to evaluate primary objectives of safety and tolerability, and secondary and exploratory objectives of pharmacokinetics, immunogenicity, pharmacodynamic (PD) biomarker effects, and antitumor activity of IO-108 as a monotherapy and in combination with pembrolizumab in patients with advanced solid tumors. The trial enrolled 25 advanced cancer patients with relapsed/refractory solid tumors. Patients received escalating doses of IO-108 (60 mg -1800 mg) intravenously once every three weeks (Q3W). Treatment with IO-108 was well-tolerated to the maximum administered dose (1800 mg Q3W); the maximum tolerated dose was not reached. Among 23 evaluable patients (11 monotherapy, 12 combination therapy plus 1 crossover), results showed 1 complete response and 4 stable disease patients in the monotherapy cohorts and 3 partial responses and 4 stable disease patients in the combination cohorts.
The 4 responding patients remain on study with an ongoing treatment duration of 8 to 12+ months as of abstract submission. Clinical benefit correlated with baseline characteristics and post-treatment changes in PD biomarkers including reprogramming of myeloid cells and activation of T cells.
“Treating patients who are refractory to treatment with T-cell immune checkpoint inhibitors remains an ongoing challenge across many tumor types,” said IO-108 Phase 1 investigator, Matthew H. Taylor, M.D., Earle A. Chiles Research Institute, Providence Cancer Institute, Portland, Oregon. “I am very encouraged by these results, particularly the complete response to IO-108 monotherapy treatment in the Merkel cell carcinoma patient who had progressed on prior anti-PD-1 treatments. These findings suggest that LILRB2 is a critically important immunotherapy target.”
The initial data from dose escalation supports further development of IO-108. The preliminary recommended Phase 2 dose (RP2D) is 1200 mg Q3W which is projected to achieve full receptor occupancy in at least 90% of patients. The ongoing IO-108 Phase 1 study is actively enrolling several biomarker-driven dose expansion cohorts, using IO-108 at RP2D as a monotherapy and in combination with anti-PD-1 antibodies (pembrolizumab, cemiplimab or tislelizumab), both in the U.S. and China.

IO-108 is a fully human IgG4 monoclonal antibody with high affinity and specificity towards LILRB2 (also known as ILT4). It blocks the interaction of LILRB2 with multiple ligands that are involved in cancer-associated immune suppression, including HLA-G, ANGPTLs, SEMA4A and CD1d. Preclinical data presented at the 2020 Society for Immunotherapy of Cancer annual meeting and the 2022 American Association for Cancer Research annual meeting demonstrate that IO-108 functions as a myeloid checkpoint inhibitor and promotes innate and adaptive anti-cancer immunity.
The ongoing Phase 1 study of IO-108 in adult cancer patients in the U.S. (NCT05054348) has completed dose escalation and is actively enrolling several expansion cohorts, as a monotherapy and in combination with anti-PD-1 antibodies (pembrolizumab or cemiplimab). To date, IO-108 has been well tolerated with demonstrated clinical activity in multiple tumor types, both as a monotherapy and in combination with pembrolizumab. The company is also actively enrolling a Phase 1 clinical trial in China to evaluate IO-108 in solid tumors, as a monotherapy and in combination with anti-PD-1 antibodies (pembrolizumab or tislelizumab).

Immune-Onc Therapeutics to Present Trial in Progress Poster for Phase 1 Study of IO-202 in Patients with Advanced Solid Tumors at the Society for Immunotherapy of Cancer Annual Meeting
– The multicenter Phase 1 study is currently enrolling and evaluating IO-202 as monotherapy and in combination with an anti-PD-1 for the treatment of solid tumors –
PALO ALTO, CA, November 10, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced that it will present a Trial in Progress poster at the Society for Immunotherapy of Cancer (SITC) Annual Meeting, being held in Boston and virtually from November 8 –12, 2022.
The poster presentation will highlight the trial design, dosing regimen, and study protocol for the company's ongoing Phase 1 clinical trial of 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 advanced solid tumors (NCT05309187).
“Our Phase 1 study of IO-202 supports a differentiated myeloid checkpoint inhibitor with best-in-class potential to provide benefit for patients with solid tumors,” said Paul Woodard, M.D., chief medical officer of Immune-Onc. “IO-202 blocks the LILRB4 pathway - specifically, interaction with its multiple ligands including apolipoprotein E and fibronectin - enabling the potential to reactivate or enhance anti-tumor T cell immune responses in patients with solid tumors.”
“In addition, we are able to study IO-202 at a higher starting dose in solid tumors by leveraging safety data from our Phase 1 trial of IO-202 in AML and CMML. We plan to combine IO-202 with various anti-PD-1s such as pembrolizumab and tislelizumab, among others. We look forward to continuing to build a strong body of evidence to support IO-102 as a novel immunotherapy with broad potential across multiple oncology indications,” he added.
This study consists of two parts: a dose escalation portion to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of IO-202 alone and in combination with pembrolizumab, an anti-PD-1; and a dose expansion portion using the recommended Phase 2 dose of IO-202 in combination with pembrolizumab or other anti-PD-1s in multiple solid tumor types. Various biomarkers will be explored to enable a mechanistic understanding of clinical data and inform future trials. This study may also provide an opportunity to identify preliminary efficacy signals for IO-202 as a monotherapy and as a combination with a PD-1 inhibitor in patients with advanced solid tumors.
Details of the presentation are as follows:
Title: A Phase 1 Trial of IO-202, An Antagonist Antibody Targeting Myeloid Checkpoint LILRB4 (ILT3), as Monotherapy and in Combination with Pembrolizumab in Adult Patients with Advanced Relapsed or Refractory Solid Tumors Abstract #: 747 Presentation Session: Clinical Trials in Progress Session Date and Time: Thursday, November 10, 2022, 9:00 AM - 9:00 PM ET
Location: Boston Convention & Exhibition Center, Hall C

ABOUT LILRB4 (also known as ILT3)
LILRB4, also known as ILT3, is an immune inhibitory transmembrane receptor expressed by monocytic myeloid cells, including dendritic cells, monocytes, monocytic myeloid-derived suppressor cells and tumor-associated macrophages. LILRB4 inhibits antigen-presenting cell function, resulting in immune tolerance. LILRB4 is also expressed on certain hematologic cancer cells. 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) and presented the rationale for targeting LILRB4 in solid tumors at the 2021 American Association for Cancer Research (AACR) Annual Meeting.
ABOUT IO-202
IO-202 is a humanized IgG1 monoclonal antibody with high affinity and specificity towards LILRB4 (also known as ILT3). It blocks the interaction of LILRB4 with multiple ligands, including ApoE and Fibronectin, and has 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 the context of solid tumors, preclinical data presented at the 2021 American Association for Cancer Research annual meeting demonstrate that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in an immune competent model in vivo.
IO-202 has two ongoing clinical studies in the U.S.: Its first Phase 1 trial is currently enrolling patients with acute myeloid leukemia (AML) or chronic myelomonocytic leukemia (CMML) as a monotherapy and in combination with azacitidine (NCT04372433). The U.S. Food and Drug Administration granted IO-202 Orphan Drug designation for treatment of AML in 2020 and Fast Track designation for relapsed or refractory AML in 2022. The second Phase 1 trial of IO-202 is currently enrolling patients with advanced solid tumors to evaluate IO-202 as a monotherapy and in combination with an anti-PD-1 (NCT05309187).

Immune-Onc Therapeutics Initiates Expansion Cohorts for IO-108 and Enters into Clinical Supply Agreement with Regeneron
– IO-108 is being studied as a monotherapy and in combination with select anti-PD-1 antibodies in multiple expansion cohorts of solid tumors –
– Clinical supply agreement with Regeneron accelerates Immune-Onc’s solid tumor clinical development program –
PALO ALTO, CA, October 17, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced the dosing of the first patient in the expansion cohorts of its ongoing Phase 1 study for IO-108. The Company also entered into a clinical supply agreement with Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) (“Regeneron”) to evaluate IO-108 in combination with Regeneron’s anti-PD-1 therapy, Libtayo® (cemiplimab), as part of its ongoing clinical development program.
IO-108 is a novel myeloid checkpoint inhibitor targeting Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4) in adult patients with advanced or refractory solid tumors.
“We are incredibly excited to have enrolled the first patient in an expansion cohort of the IO-108 study. To date, IO-108 has been well tolerated and has demonstrated promising clinical activity in various tumor types, both as a monotherapy and in combination with an anti-PD-1 antibody,” said Paul Woodard, M.D., chief medical officer of Immune-Onc. “Additionally, on the heels of initiating this important phase of our study, we are excited to enter into a supply agreement with Regeneron, which enables us to accelerate the global development of IO-108 in multiple expansion cohorts of select solid tumors. We hope to establish our pipeline products as the preferred combination agents with T cell checkpoint inhibitors and other standard of care therapies.”
The Phase 1 expansion phase includes IO-108 monotherapy cohorts and IO-108 combination cohorts with anti-PD-1 antibodies (pembrolizumab or cemiplimab, depending on tumor types). Under the terms of the agreement, Immune-Onc will sponsor and fund the planned clinical trials and Regeneron will provide cemiplimab (Libtayo®). Immune-Onc retains global development and commercial rights to IO-108.
“I have been very encouraged by both the pre-clinical and early clinical data observed for IO-108 in the ongoing Phase 1 study, and look forward to better understanding how combination therapy with various anti-PD1 therapies can further activate the body’s immune system to attack some of the hardest-to-treat cancers,” said IO-108 Phase 1 investigator, Matthew H. Taylor, M.D., assistant member, Developmental Cancer Therapeutics Laboratory and co-medical director, Providence Melanoma Program, Earle A. Chiles Research Institute, Providence Cancer Institute, Portland, Oregon. “Currently, 70-80 percent of cancer patients with solid tumors do not achieve durable responses to T-cell checkpoint therapies alone, and people with many types of cancer have yet to benefit from the promise of this class of immunotherapy. This underscores the need for investigating novel combination regimens.”

ABOUT IO-108
IO-108 is a fully human IgG4 monoclonal antibody with high affinity and specificity towards LILRB2 (also known as ILT4). It blocks the interaction of LILRB2 with multiple ligands that are involved in cancer-associated immune suppression, including HLA-G, ANGPTLs, SEMA4A and CD1d. Preclinical data presented at the 2020 Society for Immunotherapy of Cancer’s annual meeting and the 2022 American Association for Cancer Research annual meeting demonstrate that IO-108 functions as a myeloid checkpoint inhibitor and promotes innate and adaptive anti-cancer immunity.
The ongoing Phase 1 study of IO-108 in adult cancer patients in the U.S. (NCT05054348) has completed dose escalation. To date, IO-108 has been well tolerated with demonstrated clinical activity in multiple tumor types, both as a monotherapy and in combination with pembrolizumab, an anti-PD-1 antibody. The company is actively enrolling a Phase 1 clinical trial in China to evaluate IO-108 in solid tumors.
ABOUT IO-202
IO-202 is a humanized IgG1 monoclonal antibody with high affinity and specificity towards LILRB4 (also known as ILT3). It blocks the interaction of LILRB4 with multiple ligands, including ApoE and Fibronectin, and has 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 the context of solid tumors, preclinical data presented at the 2021 American Association for Cancer Research annual meeting demonstrate that IO-202 enhances dendritic cell function and T cell activation in vitro and inhibits tumor growth in an immune competent model in vivo.
IO-202 has two ongoing clinical studies in the U.S.: Its first Phase 1 trial is currently enrolling patients with acute myeloid leukemia (AML) or chronic myelomonocytic leukemia (CMML) as a monotherapy and in combination with azacitidine (NCT04372433). The U.S. Food and Drug Administration granted IO-202 Orphan Drug designation for treatment of AML in 2020 and Fast Track designation for relapsed or refractory AML in 2022. The second Phase 1 trial of IO-202 is currently enrolling patients with advanced solid tumors to evaluate IO-202 as a monotherapy and in combination with an anti-PD-1 (NCT05309187).

– Represents the first LILRB2-targeting antibody with IND clearance in China and the company’s fourth IND globally –
– A Phase 1 trial evaluating IO-108 in patients with advanced solid tumors is currently enrolling in the U.S. –
PALO ALTO, CA, May 16, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced that the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has approved the Investigational New Drug (IND) application to initiate a Phase 1 study of IO-108, a novel antagonist antibody targeting Leukocyte Immunoglobulin-Like Receptor B2 (LILRB2, also known as ILT4) for the treatment of solid tumors.
“NMPA’s timely acceptance and approval of the IND for IO-108 represents a remarkable milestone for the company,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “It is our first IND submission and clearance outside the U.S., and our company’s fourth IND globally. Antagonist antibodies targeting the LILRB family of myeloid checkpoints represent a promising new approach in cancer immunotherapy that are expected to be complementary to and synergistic with T-cell checkpoint inhibitors such as anti-PD-1 or anti-PD-L1. We look forward to bringing these first-in-class therapeutics to cancer patients in China.”
“IO-108 is a significant program in our pipeline of myeloid checkpoint inhibitors and the first LILRB2-targeting antibody with IND submission and clearance in China,” commented by Maggie Gu, China general manager of Immune-Onc. “We look forward to working closely with investigators to launch and execute the high-quality Phase 1 clinical trial to explore IO-108’s potential in treating solid tumors in China, concurrently with the U.S. Phase 1 clinical trial."
The multicenter Phase 1 study will consist of a monotherapy cohort, a combination therapy cohort, and a dose expansion cohort to evaluate the safety, tolerability, pharmacokinetics, and efficacy of IO-108 alone and in combination with pembrolizumab. The Chinese study will also confirm the recommended Phase 2 dose selected from the U.S. Phase 1 clinical trial of IO-108 in solid tumors. Immune-Onc plans to evaluate the efficacy, safety, and tolerability of IO-108 in combination with pembrolizumab in indication-specific expansion cohorts in China.
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 suppressing T cell activation and promoting tumor immune evasion.
ABOUT IO-108
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. 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 potentiates the effect of PD-1 blocking antibodies on CD4+ T cell activation in co-cultures with allogeneic macrophages. Moreover, IO-108 monotherapy inhibits the growth of solid tumors in a preclinical model, which is associated with immune cell activation. 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 in the US (NCT05054348), IO-108 has been well-tolerated to date, both as a monotherapy and in combination with pembrolizumab. The company has received the IND clearance in China and plans to evaluate IO-108 in solid tumors in China in 2H 2022.

Immune-Onc Therapeutics Announces the Selection of Clinical Development Candidate IO-106, a First-in-Class Myeloid and Stromal Checkpoint Inhibitor Targeting LAIR1
IO-106 is the third development candidate arising from Immune-Onc’s pioneering pipeline of myeloid checkpoint inhibitors, a new class of immunotherapy that aims to overcome immune resistance in cancer
The Company will present a scientific poster at the Society for Immunotherapy of Cancer (SITC) Tumor Immune Microenvironment: A Holistic Approach Workshop
PALO ALTO, CA, April 20, 2022 / Business Wire / -- Immune-Onc Therapeutics, Inc. (“Immune-Onc”), a private, clinical-stage cancer immunotherapy company developing novel biotherapeutics targeting myeloid checkpoints, today announced the selection of IO-106, a first-in-class myeloid and stromal checkpoint inhibitor targeting the inhibitory receptor, Leukocyte‐Associated Immunoglobulin‐Like Receptor 1 (LAIR1), for clinical development. The Company will present a scientific poster on the therapeutic potential of anti-LAIR1 antibodies at the Society for Immunotherapy of Cancer (SITC) Tumor Immune Microenvironment: A Holistic Approach Workshop on April 21st in San Diego, CA.
LAIR1 is an immune inhibitory receptor expressed on lymphocytes and myeloid cells that correlates with worse survival in several cancers. LAIR1 is activated by collagen which is highly abundant in the stroma of many solid tumor types and is thought to contribute to immune suppression. The data being presented suggest that LAIR1 antagonist antibodies reverse collagen-mediated immune suppression on T cells and myeloid cells in the solid tumor microenvironment, thereby promoting anti-tumor immunity.
“IO-106 is now the third clinical candidate in our pipeline and a testament to the depth and rigor of our science,” said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. “Immune-Onc was founded on groundbreaking science that first illuminated the role of the previously unexplored LILRB family of myeloid checkpoints in cancer. This research has rapidly advanced a completely new field of study and class of cancer immunotherapy that goes beyond T cells to overcome immune resistance and the limitations of current treatment options. We are very excited about potential development opportunities for IO-106 and look forward to sharing our progress in the near future.”
ABOUT LAIR1
LAIR1 is an immune inhibitory receptor of the Leukocyte Immunoglobulin-Like Receptor subfamily B (LILRB) and is expressed on lymphocytes and myeloid cells. Research shows that LAIR1 expression correlates with worse survival in several cancers. LAIR1 is activated by collagen, which is highly abundant in the stroma of many solid tumor types and is thought to contribute to immune suppression. LAIR1 is being targeted as a myeloid and stromal checkpoint in cancer immunotherapy.
ABOUT IO-106
IO-106 is a first-in-class monoclonal antibody that antagonizes LAIR1. It has broad potential in collagen-rich solid tumors and could be a candidate for combination therapy with PD-1 inhibitors and other immunotherapies. Preclinical research shows that IO-106 can reverse collagen-mediated immune suppression and mobilize anti-tumor immunity of multiple cell types including lymphocytes and myeloid cells. IO-106 entered into Investigational New Drug application (IND)-enabling studies with targeted IND submission in 1H202.
