Excerpt from the Press Release:

“PRINCETON, NJ / ACCESSWIRE / July 20, 2020 / Sonnet BioTherapeutics Holdings, Inc., (NASDAQ:SONN) a clinical-stage company developing innovative targeted biologic drugs with enhanced mono or bispecific mechanisms, announced today that it has completed initial preclinical proof-of-concept work with both GMcSF and IL-18 and with GMcSF and IL-12 in a xenograft mouse model of melanoma. This study was designed to evaluate preclinical activity of the concomitantly administered cytokines as F_HAB-derived molecules, using Sonnet’s Fully Human Albumin Binding (F_HAB) technology, in several groups of tumor-bearing mice. Sonnet’s F_HAB-derived drug candidates all showed statistically significant reduction in tumor growth compared to placebo and when compared to cytokines not derived from the Company’s platform.

The study included nine mice per active group and 12 mice in the placebo group. The Company administered a single dose as a conservative method for therapeutic lead selection. The table below summarizes the data after six days of administration of a single dose, in tumor bearing mice with an average initial cancer tumor volume of approximately 100 mm³. P values were generated for between group comparisons (treatment vs placebo) of reduction in tumor growth.”
