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)
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 VVD-133214 monotherapy, and in combination with bevacizumab or pembrolizumab, in participants with microsatellite instability (MSI) and/or deficient mismatch repair (dMMR) advanced solid tumors. VVD-133214 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, VVD-133214 may be able to block the growth of these types of cancer.
• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
• Have a microsatellite instability (MSI) and/or deficient mismatch repair (dMMR), histologically or cytologically documented advanced (unresectable and/or metastatic) solid tumor; For the combination with bevacizumab only: advanced, or metastatic colorectal adenocarcinoma (CRC) treated with at least 2 but no more than 3 prior lines of systemic therapy for the treatment of advanced CRC; For the combination with pembrolizumab only: Histologically confirmed locally advanced, or metastatic CRC with no prior systemic treatment for metastatic disease and not amenable to surgery
• Have received and then progressed following, or are intolerant to, standard therapy in the advanced setting
• Presence of measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
• Life expectancy of at least (≥)12 weeks
• Availability of formaldehyde-fixed paraffin-embedded (FFPE) archival tumor tissue for submission to Sponsor/central laboratory for retrospective central testing; for participants without archival tissue, a biopsy from either primary or metastatic tumor lesion, deemed medically feasible, must be taken
• Adequate hematologic, end-organ, and cardiovascular function, as defined in the protocol
