– Early signs of clinical activity were observed in patients receiving TransCon TLR7/8 Agonist as monotherapy or in combination with pembrolizumab; abscopal effect observed with monotherapy
– With a single injection, TransCon TLR7/8 Agonist demonstrated sustained target immune system engagement over weeks in injected and non-injected tumors, with no signs of systemic toxicity
COPENHAGEN, Denmark, Nov. 11, 2022 (GLOBE NEWSWIRE) — Ascendis Pharma A/S (Nasdaq: ASND) today disclosed new data from the dose-escalation portion of transcendIT-101, the company’s Phase 1/2 open-label, multi-center trial of TransCon TLR7/8 Agonist in patients with advanced solid tumors. TransCon TLR7/8 Agonist is an investigational long-acting prodrug designed to provide sustained, localized release over weeks of resiquimod (a potent immune response modifier with clinically demonstrated anti-tumor activity) with low systemic exposure.
The dose escalation data from transcendIT-101, presented by Diwakar Davar, M.D. of the University of Pittsburgh Medical Center during the annual meeting of the Society for Immunotherapy of Cancer (SITC 2022), suggests that intratumoral TransCon TLR7/8 Agonist was safe and well-tolerated alone or in combination with pembrolizumab; that it demonstrated target immune system engagement in injected and non-injected tumors along with a systemic immune response; and that it showed early signs of clinical activity alone or in combination with pembrolizumab.
“We are very pleased to see intratumoral TransCon TLR7/8 Agonist administration working as designed to deliver prolonged, high local concentrations of resiquimod, steadily activating and intensifying the body’s innate and adaptive immune responses over weeks with a single injection,” said Stina Singel, Senior Vice President, Head of Clinical Development, Oncology at Ascendis Pharma. “With these early signs of clinical activity, including monotherapy abscopal activity, and no signs of systemic toxicity, we look forward to continuing our work with investigators and patients to further assess TransCon TLR7/8 Agonist’s ability to promote potent anti-tumoral responses while minimizing toxic systemic exposures.”
All 23 of the patients enrolled in the dose escalation portion of the trial had advanced or metastatic solid tumors that had progressed on prior treatments, 9 in the monotherapy cohort (intratumoral TransCon TLR7/8 Agonist alone) and 14 in the combination therapy cohort (intratumoral TransCon TLR7/8 Agonist plus the check-point inhibitor pembrolizumab). Two dose levels were evaluated: 0.3 mg/lesion and 0.5 mg/lesion. The recommended Phase 2 dose was declared at 0.5 mg/lesion for up to two lesions.
The Phase 1/2 transcendIT-101 trial (NCT04799054) is continuing to enroll patients, with dose expansion focused on investigating TransCon TLR7/8 Agonist in combination with pembrolizumab in 4 cancer types where increased Toll-like receptor (TLR) activity has potential to improve adaptive immune activation and host defense against cancers: head and neck squamous cell carcinomas (SCC); other HPV-associated cancers; melanoma; and cutaneous squamous cell carcinomas (cSCC).

About TransCon TLR7/8 Agonist
Immunotherapies can stimulate, intensify, and sustain the immune system’s natural ability to recognize and eliminate cancer cells, yet many patients do not respond to immunotherapies currently on the market, most of which are designed for intravenous administration and many of which have significant toxicity profiles at therapeutically effective doses. TransCon TLR7/8 Agonist is an investigational long-acting prodrug of resiquimod (a potent immune response modifier with clinically demonstrated anti-tumor activity) designed to provide sustained activation of intratumoral antigen-presenting cells driving tumor antigen presentation and induction of immune-stimulatory cytokines for weeks with a single intratumoral injection. Based on Ascendis Pharma’s innovative TransCon technology platform, TransCon TLR7/8 Agonist is comprised of 3 main components: resiquimod a small molecule agonist of Toll-like receptors (TLRs) 7 and 8, a TransCon hydrogel microparticle carrier, and a linker bound permanently to the hydrogel microparticle carrier on one end and transiently to resiquimod on the other. TransCon TLR7/8 Agonist leverages TransCon hydrogel to achieve sustained, localized release of resiquimod in the injected tumor over weeks, where it is designed to steadily activate and intensify the body’s innate and adaptive immune responses to eradicate cancer cells in both injected and distal tumors, while maintaining low systemic drug exposure.
