Safety, efficacy, pharmacokinetic, and pharmacodynamic endpoints will be monitored and reported. DDR1 expression levels on tumors, circulating DDR1, molecular and cellular changes in the TME, and changes on CD8 PET imaging will also be assessed.
This study not only paves a pathway for the development of PRTH-101 as a cancer therapeutic, but also sheds light on a new therapeutic strategy to modulate collagen alignment in the tumor ECM for enhancing antitumor immunity.
