Incendia Therapeutics Enrolls First Patient in Phase 1c Clinical Trial of PRTH-101, a Novel DDR1 Inhibitor
September 10, 2024
– Phase 1c study of PRTH-101 alone or in combination with KEYTRUDA® in patients with advanced or metastatic solid tumors will inform optimal design of the Phase 2/3 study
– PRTH-101 demonstrated favorable safety profile in Phase 1a and 1b studies
CAMBRIDGE, Mass.--September 10, 2024 --Incendia Therapeutics, a precision oncology company discovering and developing a novel class of therapies that reprogram the tumor microenvironment (TME), today announced that the first patient has been enrolled in the Phase 1c study of PRTH-101 for the treatment of patients with advanced or metastatic solid tumors.
“In our Phase 1a and 1b studies, we were able to select an optimal dose and identify potential biomarkers to carry forward” said Irena Webster, SVP Development and Operations of Incendia. “The data from this study will inform the design of the Phase 2/3 program, for which planning and global feasibility are currently underway.”
Dr. Joseph Paul Eder, CMO, added “Incendia, with its outstanding team of investigators and investigative sites, has determined a recommended Phase 2 dose of PRTH 101. PRTH 101 has shown consistent safety as a single agent and in combination with pembrolizumab. We will now focus on tumor types that have demonstrated signs of clinical activity and patient benefits.”
The Phase 1c study will evaluate the safety, tolerability and anti-tumor activity of PRTH-101 as both a monotherapy and in combination with KEYTRUDA® (pembrolizumab).
About PRTH-101
PRTH-101 is a therapeutic antibody that targets DDR1, a collagen binding protein and kinase present on epithelial cells. Some tumor cells are believed to co-opt DDR1 – collagen binding to build an impenetrable barrier around the tumor. By allosterically disabling DDR1, PRTH-101 disrupts tumor associated collagen alignment to permit immune cell access into the tumor core. In preclinical experiments, PRTH-101 mediated DDR1 blockade has demonstrated both single agent anti-tumor activity as well as marked augmentation of checkpoint inhibitor function. Tumor types that express high levels of DDR1-associated collagen barriers include thymic, colorectal, pancreatic, ovarian, glioma, and non-small cell lung cancer. Currently, there are no approved drugs that target DDR1.
About the Phase 1 Trial
The Phase 1 trial (NCT05753722) is a multi-center, open-label, dose escalation and dose expansion study that is expected to enroll up to 270 patients in the US with advanced or metastatic solid tumors. The goals of the study are to assess safety and tolerability of PRTH-101, evaluate anti-tumor activity in select indications alone and in combination with anti-PD-1 inhibitors, and determine dosing regimens for the Phase 2 clinical program. In addition to examining the clinical profile of PRTH-101, the trial will evaluate DDR1 and pathway-related proteins as predictive biomarkers for patients whose tumors respond to treatment.
