  • AURELIO-04 will enroll up to 320 patients and test the combination in multiple solid tumor indications
  • Clinical collaborator, MSD (Merck & Co., Inc., Rahway, NJ, USA), will supply KEYTRUDA for the study that is being conducted in Europe and the US

SOTIO Biotech, a clinical stage immuno-oncology company owned by PPF Group, announced today that the first patient was dosed in its Phase 2, AURELIO-04 combination trial of SOT101, an IL-15 superagonist and MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy KEYTRUDA® (pembrolizumab), in patients with selected advanced/refractory solid tumors.

“The initiation of this Phase 2 study is a significant milestone for the clinical development of SOT101,” said Richard Sachse, M.D., Ph.D., Chief Medical Officer of SOTIO and Managing Director of SOTIO Biotech in Switzerland. “IL-15 has been widely favored as a promising cytokine in oncology, but IL-15-based approaches to date have fallen short of realizing this promise due to aberrant targeting and adverse events. SOT101 in combination with KEYTRUDA has shown encouraging early clinical efficacy in the AURELIO-03 phase 1 study and we look forward to building upon our findings to advance this innovative therapy for the potential benefit of patients battling cancer.”

The Phase 2 trial (NCT05256381) is an open-label, single-arm, multicenter study of SOT101 in combination with pembrolizumab to evaluate efficacy and safety in patients with selected advanced/refractory solid tumors. The initiation of AURELIO-04 is based on encouraging data from the Phase 1/1b AURELIO-03 study of SOT101 which showed encouraging early efficacy signals in combination with pembrolizumab, and as single-agent treatment. The Phase 2 trial will enroll up to 320 patients targeting multiple solid tumor indications across 55 trial sites in Europe and the US. SOTIO entered into a clinical trial collaboration and supply agreement with MSD (a tradename of Merck & Co., Inc., Rahway, NJ, USA) last year in December. MSD will supply KEYTRUDA for the study.

The first patient was dosed at the Masaryk Memorial Cancer Institute, Brno, Czech Republic, under the supervision of Peter Grell, M.D., Ph.D., as principal investigator.

Stéphane Champiat, M.D., Ph.D., Head of the Inpatient Unit at the Drug Development of Gustave Roussy Cancer Center and coordinating investigator of AURELIO-04 trial commented: “The continued clinical development of SOT101 is crucial as we still face a significant need to provide more effective therapeutic options for patients with solid tumors. Validated by promising Phase 1/1b AURELIO-03 data, AURELIO-04 will aim to confirm safety and demonstrate efficacy of SOT101 in combination with pembrolizumab in additional indications.”
