A Phase I, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Anti-Tumor Activity of VVD-133214 as Monotherapy and in Combination in Participants With Advanced Solid Tumors Harboring Microsatellite Instability (MSI) and/or Deficient Mismatch Repair (dMMR)
Considering participating in a START clinical trial?
Study Summary
This is a first-in-human, Phase I, open-label, multicenter, dose-escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity of RO7589831 monotherapy in participants with microsatellite instability (MSI) and/or deficient mismatch repair (dMMR) advanced solid tumors. RO7589831 is an oral drug that acts on a protein called Werner (WRN), which may promote the growth of cancers that are MSI and/or dMMR. By acting on WRN, RO7589831 may be able to block the growth of these types of cancer. To evaluate VVD-214 as a monotherapy and in combination with pembrolizumab as a treatment option for patients with solid tumors that display high MSI or deficient mismatch repair (dMMR) including but not limited to colorectal, endometrial, ovarian and gastric cancers
