An Open-label, Single-arm, Phase Ib/IIa Trial to Evaluate the Safety and Efficacy of the EP4 Receptor Antagonist CR6086 in Combination With the PD-1 Inhibitor Balstilimab (AGEN2034), in Patients With Pretreated Mismatch-repair-proficient and Microsatellite Stable Metastatic Colorectal Cancer

This Phase Ib/IIa study has been designed according to a 3+3 dose escalation/dose expansion design. A dose expansion will be conducted at both the intermediate and high dose levels, if tolerated, with the purpose of generating additional and more robust safety and preliminary efficacy data. No control arm was included, as the target patient population of this study consists of patients in whom the overall survival is less than 6 months and treatment options are very limited and often poorly tolerated, making unlikely that the study results can be significantly biased.

A Randomized, Double Blind, Placebo-controlled, Dose Response, Phase II, Multicentre Trial to Evaluate the Efficacy, Safety and Pharmacokinetics of Oral CR6086 Administered at the Doses of 30, 90 or 180 mg Bid for 12 Weeks in Combination With Methotrexate, in DMARD-naïve Patients With Early Rheumatoid Arthritis

CR6086 is a new, potent and selective, orally available, small molecule prostaglandin EP4 receptor antagonist, endowed with immunomodulatory properties. The pharmacological properties of CR6086, along with its oral bioavailability, predictable pharmacokinetics and good safety, make it the ideal candidate to be tested alone or in combination with methotrexate (MTX) in patients with early Rheumatoid Arthritis who are naïve to Disease-Modifying Antirheumatic Drugs (DMARDs). The compound has indeed the potential to provide a safer and more effective treatment than MTX (or other conventional synthetic DMARDs - csDMARDs), and could significantly improve the proportion of responder patients and avoid/delay the recourse to biological DMARDs (bDMARDs) or targeted synthetic DMARDs (tsDMARDs).

BACKGROUND:

Prostaglandin E₂ (PGE₂) acts via its EP4 receptor as a cytokine amplifier (e.g., interleukin [IL]-6) and induces the differentiation and expansion of inflammatory T-helper (Th) lymphocytes. These mechanisms play a key role in the onset and progression of rheumatoid arthritis (RA). We present the pharmacological characterisation of CR6086, a novel EP4 receptor antagonist, and provide evidence for its potential as a disease-modifying anti-rheumatic drug (DMARD).

METHODS:

CR6086 affinity and pharmacodynamics were studied in EP4-expressing HEK293 cells by radioligand binding and cyclic adenosine monophosphate (cAMP) production, respectively. In immune cells, IL-6 and vascular endothelial growth factor (VEGF) expression were analysed by RT-PCR, and IL-23 and IL-17 release were measured by enzyme-linked immunosorbent assay (ELISA). In collagen-induced arthritis (CIA) models, rats or mice were immunised with bovine collagen type II. Drugs were administered orally (etanercept and methotrexate intraperitoneally) starting at disease onset. Arthritis progression was evaluated by oedema, clinical score and histopathology. Anti-collagen II immunoglobulin G antibodies were measured by ELISA.

RESULTS:

CR6086 showed selectivity and high affinity for the human EP4 receptor (K_i = 16.6 nM) and functioned as a pure antagonist (half-maximal inhibitory concentration, 22 nM) on PGE₂-stimulated cAMP production. In models of human immune cells in culture, CR6086 reduced key cytokine players of RA (IL-6 and VEGF expression in macrophages, IL-23 release from dendritic cells, IL-17 release from Th17 cells). In the CIA model of RA in rats and mice, CR6086 significantly improved all features of arthritis: severity, histology, inflammation and pain. In rats, CR6086 was better than the selective cyclooxygenase-2 inhibitor rofecoxib and at least as effective as the Janus kinase inhibitor tofacitinib. In mice, CR6086 and the biologic DMARD etanercept were highly effective, whereas the non-steroidal anti-inflammatory drug naproxen was ineffective. Importantly, in a study of CR6086/methotrexate, combined treatment greatly improved the effect of a fully immunosuppressive dose of methotrexate.

CONCLUSIONS:

CR6086 is a novel, potent EP4 antagonist showing favourable immunomodulatory properties, striking DMARD effects in rodents, and anti-inflammatory activity targeted to immune-mediated inflammatory diseases and distinct from the general effects of cyclooxygenase inhibitors. These results support the clinical development of CR6086, both as a stand-alone DMARD and as a combination therapy with methotrexate. The proof-of-concept trial in patients with RA is ongoing.

Agenus Advances Portfolio with 6 Clinical Collaborations

LEXINGTON, Mass., May 31, 2022 (GLOBE NEWSWIRE) -- Agenus Inc. (NASDAQ: AGEN), an immuno-oncology company with an extensive pipeline of therapeutics designed to activate the immune response to cancers and infections, today announced that it has entered into 3 new clinical collaborations with Targovax, Oxford BioTherapeutics, and Immunogenesis, doubling its current number of clinical collaborations. These 6 collaborations span a range of Agenus’ clinical assets, including botensilimab (Fc-enhanced anti-CTLA-4), balstilimab (anti-PD-1), zalifrelimab (anti-CTLA-4), and QS-21 STIMULON™. Agenus is pursuing partnerships with companies developing agents with complementary mechanisms, paving the way for promising immunotherapy combinations to address immunosuppression in the tumor microenvironment. The combination studies are being sponsored and executed by our collaborators, with drug supply and scientific support provided by Agenus. This strategy, enabled by in-house integrated manufacturing and scientific capabilities, positions Agenus to achieve the insights and advances needed to drive development on accelerated timelines. “These new collaborations with Targovax, Oxford BioTherapeutics, and Immunogenesis are exciting next steps in our partnership strategy to broaden combinations and indications under evaluation with our immunomodulatory antibodies,” said Dr. Steven O’Day, Chief Medical Officer at Agenus. “We believe these combinations may unlock the power of immunotherapy more broadly, potentially offering new and promising benefit to patients with treatment-resistant solid tumors.” Agenus’ new and ongoing clinical collaborations are supporting and enabling: Targovax to conduct a clinical trial combining botensilimab and balstilimab with ONCOS-102 (oncolytic virus) in patients with PD-1 relapsed/refractory melanoma. ONCOS-102 is designed to induce immune activation and immunogenic cell death to improve response to immunotherapy.Oxford BioTherapeutics to conduct a clinical trial combining balstilimab with OBT076 (CD205-targeting antibody-drug conjugate) in patients with solid tumors, including lung, gastric, and ovarian cancer. OBT076 is expected to deplete CD205+ cancer cells, and immuno-suppressive cells within the tumor microenvironment, leading to T cell activation and increased response to immunotherapy.Immunogenesis to conduct a clinical trial combining balstilimab and zalifrelimab with evofosfamide (hypoxia-reversal agent) in patients with advanced solid tumors, including prostate, pancreatic, HPV-negative head and neck cancer. Evofosfamide is anticipated to reduce tumor hypoxia and restore T cell infiltration and activity within the tumor microenvironment, increasing responsiveness to checkpoint therapy.Targovax to conduct a clinical trial combining QS-21 STIMULON with TG01 (KRAS vaccine) in up to 3 cancer indications, including multiple myeloma. TG01 is designed to induce T cells that recognize and destroy mut-RAS cancer cells; QS-21 STIMULON is expected to improve immune cell recognition, activation, and TCR diversity of the immune response.Rottapharm Biotech is conducting a clinical trial combining balstilimab with CR6086 (EP4 antagonist) in patients with pMMR-MSS colorectal cancer. CR6086 is expected to inhibit the immune suppressive role of prostaglandins in the tumor microenvironment, improving immunogenicity and responsiveness to immunotherapy. The Phase 1/2 study commenced in 2021.Nelum is conducting a clinical trial combining zalifrelimab with NLM-001 (hedgehog inhibitor) and chemotherapy in patients with advanced pancreatic cancer. NLM-001 in combination with chemotherapy is anticipated to condition the tumor microenvironment to improve T cell infiltration, activation, and responsiveness to immunotherapy. The Phase 1/2 study commenced in 2021.
