IDs, checkpoint therapy, targeted antibody therapy and low-dose chemotherapy. Tumor eradication by our technology was associated with induction of both innate and adaptive immunological memory and, importantly, did not require provision of or targeting a tumor antigen in preclinical models. We have carried out successful current Good Manufacturing Practice (cGMP) manufacturing of our lead clinical candidate, Decoy20.

In May 2022, the U.S. Food and Drug Administration, or the FDA, allowed us to proceed under our IND for a Phase 1 clinical trial in participants with advanced solid tumors where currently approved therapies have failed. In December 2022, we initiated an open label, multi-center, dose escalation and expansion, single arm (monotherapy) Phase 1 study conducted in 2 parts. The Phase 1 study began with single dose administration and has now been followed with continuous weekly dosing of Decoy20 in tumor-specific expansion cohorts. The study is enrolling participants with any one of six advanced/metastatic solid tumors, who have exhausted approved treatment options. The study’s objectives are to assess the safety and tolerability of Decoy20, to determine the maximum tolerated dose, the optimal biologically active and recommended Phase 2 dose, as well as to assess Decoy20 pharmacokinetics (PK), pharmacodynamics and clinical activity. The primary endpoints of the study are incidence, relatedness and severity of adverse events and treatment-emergent adverse events and determining the number of subjects per cohort with dose limiting toxicity-based adverse events. Secondary endpoints include the incidence of anti-drug antibodies and neutralizing antibodies pre- and post-treatment, change in Decoy20 PK parameters over time, objective response rate and duration of response.

In August 2023, we evaluated the first four participants who received a single dose of 7 x 10^7 Decoy20 in Part 1 of the Phase 1 clinical trial. All four participants who enrolled were evaluable in the first cohort. These participants experienced generally anticipated transient adverse events including hemodynamic changes such as changes in pulse or blood pressure that resolved within 30 minutes and laboratory abnormalities such as grade 1-3 elevations in transaminases (liver function tests) and grade 4 reductions in lymphocytes that generally resolved within three days. One participant had a dose-limiting toxicity of grade 3 bradycardia (slow heart rate) and grade 2 hypotension (low blood pressure) which resolved within approximately 90 minutes with i.v. fluids.
