Sagiv-Barfi et al. The IMPULSE phase II study evaluated the efficacy and safety of lefitolimod as maintenance treatment in extensive-stage small-cell lung cancer (ES-SCLC) after objective response to first-line. Anti-OX40 antibody is a monoclonal antibody that enhances the activation of T cells, immune cells that are important for fighting tumors Radiation therapy uses high energy x-rays to kill cancer cells and may make them more easily detected. A preclinical programme is ongoing to broaden the results obtained to date and we are now preparing for a Phase I clinical trial using NanoZolid combined with a TLR9 agonist. TLRs play a critical role in defense against invading pathogens but are also involved in other serious pathological processes, such as tumorigenesis [1]. According to phase Ib study findings presented at the 2018 AACR Annual Meeting, combining the intratumoral toll-like receptor 9 (TLR9) agonist CMP-001 and pembrolizumab (Keytruda) showed clinical activity in reversing PD-1 checkpoint inhibition resistance in patients with metastatic melanoma. combination with the TLR9 agonist SD-10189 and radiation therapy90 in patients with recurrent low-grade B-cell lym-phoma (NCT02254772). 7–10 Synthetic TLR4 and TLR9 agonists have been assessed as adjuvants of allergen-specific immunotherapy with the hope that they may boost Th1/T regulatory (Treg) cell-type anti-allergic activity and thus enhance the clinical benefit. About this Clinical Trial. This phase I trial studies the side effects and best dose of the anti-OX40 antibody BMS-986178 when given together with the TLR9 agonist SD-101 and radiation therapy in treating patients with low-grade B-cell Non-Hodgkin lymphomas.

UPPSALA, SWEDEN - LIDDS AB (publ) has performed preclinical studies using a TLR9 agonist formulated with NanoZolid® (NZ-TLR9) showing that a single NZ-TLR9 injection is reducing tumor growth and improves the survival rate. Arguably, the most impressive antitumor responses observed have been in patients with bladder cancer treated with BCG, which is composed of a "mixture" of. TLR9 agonists are DNA-based molecules that contain several non-methylated CG-motifs for TLR9 recognition. The only known agonist for this TLR is poly‐ICLC (and its derivatives), which is being investigated in various clinical trials. TLR9 agonists are usually oligonucleotides comprising short, DNA-like sequences, which mimic the CpG motifs found in some intracellular pathogens, thereby triggering the body's immune response. Patients underwent treatment at lesion A with radiation (XRT) with 2 Gy per day on days 1 and 2. --(BUSINESS WIRE)--Dec.

In this context, intra-tumoral ODN1826 combined with systemic CTLA-4 blockade to extend survival versus control ( p = 0. Mobilizing endogenous T cells to fight tumors is the goal of many immunotherapies. Imiquimod is currently the only TLR7 agonist approved for clinical use, for treatment of superficial skin cancer in the Aldara TM cream, but a number of clinical trials are being conducted with. Purpose: K-Ras somatic mutations are a strong predictive biomarker for resistance to epidermal growth factor receptor (EGFR) inhibitors in patients with colorectal and pancreatic cancer. Oligodeoxynucleotides containing unmethylated CpG motifs (CpG) are well known TLR9 agonists. Earlier work has shown that an increase in interferon gene expression is correlated with responses to programmed death 1 (PD-1. This market is attractive as evidenced by companies developing ligands to TLRs, such as Idera Pharma with a TLR9 agonist for solid tumor types and metastatic melanoma that is in Phase 1/2 trials, Dynavax with a TLR9 agonist for low grade B-cell lymphoma and metastatic melanoma in Phase 1/2 trials, Cleveland BioLabs with a synthetic TLR5. TLR9 seems to have evolved to detect the unmethylated CpG dinucleotides that are relatively common in bacterial and viral genomic DNAs but are uncommon in. TLR9 agonists have been shown to be most effective when injected directly into a tumor, says Monica Wallter. The in vivo efficacy is as good as with repeated injections of the standard TLR9 agonist.

Various clinical trials are currently ongoing to determine the efficacy of CpG ODNs as a therapeutic tool for atopic diseases. In addition to TLR4- and TLR9-targeting agonist adjuvants, various other PRR agonist adjuvants have been evaluated in human clinical trials. CMP -001 is designed to induce both innate and adaptive anti -tumor immune responses, thereby converting immunolog ically "cold" tumors into immunologically "hot" tumors, with the potential to mediate tumor regression. Mologen's chief executive Matthias Schroff says, for example, that its DNA-based TLR9 agonist MGN1703 can be given at a dose ten times higher than the dose of CPG 7909 used in Pfizer's NSCLC trials. The cells were stimulated with 852A, imiquimod, 3M-002, CpG2059, or vehicle at the concentrations indicated (log scale).

Specific TLR9 agonist-modulated glycosylation changes were associated with reductions in the amount of HIV that persists during standard-of-care antiretroviral therapy. In a clinical trial, 29 patients received low-dose irradiation and injections of SD-101 directly into their tumors (intratumoral injections). Our most advanced clinical trial ILLUMINATE-301, is currently in Phase 3 and enrolling patients with anti-PD-1 refractory metastatic. 94, 95 The success and ubiquitous nature of poly‐ICLC led to the belief that this was the only realistic possibility for targeting this TLR; however, recent studies have identified other small molecules that can. The TLR9 agonist used in these studies was SD-101, Dynavax's lead clinical candidate currently being developed as an intratumoral agent in combination with anti-PD-1 therapy in patients with. However, there have been also some disappointing results with one pharmaceutical company recently dropping its clinical program with a TLR9 agonist in non-small cell lung cancer.

Multi-TLR Agonists: Potential for Therapeutic Success TLRs are sensors of microbial components as well as host-derived endogenous molecules released by injured tissues. The only known agonist for this TLR is poly‐ICLC (and its derivatives), which is being investigated in various clinical trials. Commenting on the return of rights to the TLR9 agonist program, Dr. 94, 95 The success and ubiquitous nature of poly‐ICLC led to the belief that this was the only realistic possibility for targeting this TLR; however, recent studies have identified other small molecules that can. Studies in mice have demonstrated that local intratumoral injection of an oligonucleotide containing immunostimulatory CpG motifs (CpG-ODN) signaling through Toll-like receptor-9 (TLR9) can control tumor growth by coordinated activation of both innate and adaptive responses ().
