Second Life Therapeutics is developing SL-28, an allogeneic, non-genetically modified cell-based therapy for the treatment of advanced solid tumours. The company has recently demonstrated a novel, non-genetic approach to modulate immune cell activity through targeted manipulation of the Universal Receptive System. The purpose of this open label, multi-center clinical trial is to evaluate the anti-tumor activity, safety, and pharmacokinetics, single-agent SL-28 in patients with a diverse array of solid tumors. The study includes an initial Phase 1 dose escalation to determine recommended dose(s) for expansion of SL-28 as a monotherapy and Phase 2 expansion cohorts. The study will enroll patients with advanced solid tumours, including those who failed previous lines of chemo- and immunotherapies.

The primary objective is to determine whether pretreatment-to-posttreatment changes in circulating multigene methylation levels correlate with objective response rates (ORR) assessed by contrast-enhanced CT/MRI and levels of serum tumor markers. Secondary endpoints include: (a) time-dependent association between methylation fluctuation patterns and progression-free survival (PFS), (b) comparative diagnostic accuracy of methylation indices versus conventional biomarkers, and (c) feasibility of using methylation thresholds to guide adaptive therapy modification.
