Oncology (MRx0518)
4D pharma’s MRx0518 is the world's first Live Biotherapeutic to show positive signals of clinical activity in cancer. We are currently investigating the effects of MRx0518 in a wide range of solid tumor types and treatment settings.
Phase I/II Keytruda® combination study in ICI-refractory solid tumors
In collaboration with Merck & Co., known as MSD outside the United States and Canada, we are conducting a Phase I/II investigation of the combination of MRx0518 and Keytruda® (pembrolizumab) in patients with advanced or metastatic non-small cell lung cancer, kidney cancer, bladder cancer or melanoma who are refractory to prior anti-PD-1/PD-L1 therapy.
The trial is made up of two parts – Part A, an initial safety phase assessing dose-limiting toxicities after one three-week cycle of treatment in addition to clinical benefit, and the Part B cohort expansion phase. Part A was successfully completed in May 2020, and the safety review committee determined that it is safe to proceed to Part B of the study, which is ongoing. This study is being conducted at multiple sites in the United States.
Below is the clinical benefit analysis of all 12 patients enrolled in Part A (as of 21 August 2020):
