Results reinforce potential to develop TILT-123 as a systemic therapy in Phase II setting HELSINKI, Finland I September 09, 2024 I TILT Biotherapeutics (TILT), a clinical-stage biotechnology company developing cancer immunotherapies, announces that it will present data at the European Society of Medical Oncology (ESMO) Congress 2024. The results further demonstrate the potential for TILT-123 as an intravenous therapy. The data presented covers the results of a Phase I clinical cohort of TILT-123 monotherapy for the treatment of advanced solid cancers (NCT04695327), demonstrating the regimen is safe, resulting in tumor transduction and immunological effects in metastases. A fully intravenous delivery regimen of TILT-123 was studied in a total of 6 patients, whose cancer types included three rectal carcinomas, gastric intestinal type carcinoma, pancreatic ductal adenocarcinoma, and liposarcoma. TILT-123 was administered twice daily, first twice a week and subsequently at 3-week intervals. Of patients evaluable by imaging by data cutoff, disease control was seen in 33% of patients with RECIST1.1 and 66% of patients with PET-based criteria. Updated data will be presented at the meeting (1). TILT Biotherapeutics’ founder and CEO, Akseli Hemminki, a cancer clinician who has personally treated hundreds of cancer patients with oncolytic viruses, said “This data presented at ESMO 2024 provides additional validation on the potential of TILT-123 as fully intravenous therapy in very difficult to treat patient population. I am also proud of our progress with two other studies investigating the fully intravenous regimen of TILT-123. We are moving according to our plan towards Phase II and making good clinical progress.” TILT-123, an oncolytic adenovirus armed with tumor necrosis factor alpha (TNFα) and interleukin-2 (IL-2), is designed to enhance the efficacy of T-cell therapies, including immune checkpoint blockade or adoptive cell transfer. TILT’s approach uses oncolytic viruses to selectively replicate in and lyse cancer cells, while simultaneously stimulating immune responses towards the tumor.

The company’s patented TILT ® technology can be delivered intravenously, locoregionally, or intratumorally. It modifies the tumor microenvironment and has a broader systemic effect.

Over sixty patients have been treated in five international trials sponsored by the company with promising initial efficacy responses observed in some of the patients. The company’s pioneering approach has been recognized by industry leaders. It has two collaborations with MSD (Merck & Co., Inc., Rahway, NJ, USA) investigating TILT-123 in combination with KEYTRUDA ® (pembrolizumab) in ovarian cancer (NCT05271318) and in refractory non-small cell lung cancer (NCT06125197).

Results reinforce potential to develop TILT-123 as a systemic therapy HELSINKI, Finland, May 28, 2024 (GLOBE NEWSWIRE) -- TILT Biotherapeutics (TILT), a clinical-stage biotechnology company developing cancer immunotherapies, announces that it will present two abstracts at the American Society of Clinical Oncology (ASCO) Annual Meeting 2024. Abstract (5562) demonstrates promising safety and efficacy data of TILT-123 in ovarian cancer patients, whilst abstract (2658) demonstrates the potential for TILT-123 as an intravenous therapy. Abstract (5562)* covers the results of a Phase I clinical trial of TILT-123 in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy KEYTRUDA® (pembrolizumab), for the treatment of platinum-resistant or -refractory ovarian cancer, demonstrating the combination is safe and appears to induce disease control in a difficult-to-treat patient population. 14 patients (out of 15 enrolled) were evaluable for treatment response, with disease control achieved in 64.3%. Analysis of biological samples indicated the presence of TILT-123 and induction of T cells in injected and non-injected lesions. Long term survival was seen in some patients: Median progression free survival (PFS) and overall survival (OS) in all patients were 105 and 280 days. In patients with stable disease (SD) on day 92 by RECIST 1.1, median PFS was 174 days and median OS was 293 days. Abstract (2658) introduces the development of oncolytic adenovirus TILT-123 as an intravenous (IV) therapy. Results across three Phase I trials showed that IV delivery results in systemic tumor transduction and accumulation of lymphocytes at tumors. This means TILT-123 reached tumors, despite not being directly injected into them, and successfully triggered an immune system toward the cancer. The IV injection of TILT-123 results in persistence of the virus in peripheral blood for up to 7 days. Tumor transduction was observed in 75% of patients in three Phase I trials on day 8 post TILT-123 systemic administration. TILT Biotherapeutics’ founder and CEO, Akseli Hemminki, a cancer clinician who has personally treated hundreds of cancer patients with oncolytic viruses, said “This data presented at ASCO 2024 provides additional validation as we move forward in our clinical trials for patients with resistant or refractory ovarian cancer that have few other treatment options.” TILT-123, an oncolytic adenovirus armed with tumor necrosis factor alpha (TNFα) and interleukin-2 (IL-2), is designed to enhance the efficacy of T-cell therapies, including immune checkpoint blockade or adoptive cell transfer. TILT’s approach uses oncolytic viruses to selectively replicate in and lyse cancer cells, while simultaneously stimulating immune responses towards the tumor.
