Ascendis Pharma A/S Presents New Non-Clinical Data for TransCon™ TLR7/8 Agonist Oncology Program at SITC 2021
- In non-clinical models, a single dose of TransCon™ TLR7/8 Agonist activated critical innate and adaptive immune mechanisms, providing sustained modulation of tumor microenvironments with low systemic exposure.
- Company on track to announce initial monotherapy clinical data for TransCon TLR7/8 Agonist
later this quarter.
The data show that, as designed, TransCon TLR7/8 Agonist, which leverages the Company’s innovative TransCon hydrogel technology, provides sustained activation of both innate and adaptive immune mechanisms with low systemic cytokine levels.
The posters being presented at SITC 2021 are:
|A Single Dose of Intratumoral TransCon TLR7/8 Agonist Monotherapy Promoted Sustained Activation of Antigen Presenting Cells Resulting in CD4+ and CD8+
T Cell Activation and Tumor Growth Inhibition
|Tumor Growth Inhibition Mediated by a Single Dose of Intratumoral TransCon TLR7/8 Agonist Associated with Activated Circulating T and B cells and Sustained Low Levels of Systemic Cytokines
“We are designing TransCon TLR7/8 Agonist for sustained and controlled release of resiquimod, a potent TLR7/8 agonist, with the goal of maximizing therapeutic benefit and addressing the known limitations of current approaches, including serious systemic toxicity and rapid effusion from the tumor,” said Juha Punnonen, Ascendis Pharma’s Senior Vice President and Head of Oncology. “We are incredibly pleased to confirm with these non-clinical studies that a single intratumoral injection of sustained release unmodified resiquimod delivered through our unique hydrogel technology worked in the expected way. We look forward to sharing initial data from our Phase 1/2 clinical trial soon.”
About TransCon TLR7/8 Agonist
TransCon TLR7/8 Agonist is an investigational long-acting prodrug of resiquimod, a small molecule agonist of Toll-like receptors (TLR) 7 and 8 designed to provide sustained activation of intratumoral antigen-presenting cells driving tumor antigen presentation and induction of immune stimulatory cytokines for weeks or months with a single intratumoral injection.
