  • "Participants will: * Receive KQB365 infusion weekly alone, in combination with cetuximab, or in combination with oral KQB198. * Visit the clinic about 9 times in the first 6 weeks, and then once every week after that."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

The goal of this clinical trial is to learn if KQB365 works to treat advanced solid tumor cancer in adults. It will also learn about the safety of KQB365. The main questions it aims to answer are: * What is the safe dose of KQB365 by itself, in combination with cetuximab, or in combination with KQB198? * Does KQB365 alone, in combination with cetuximab, or in combination with KQB198 decrease the size of the tumor? * What happens to KQB365 in the body? Participants will: * Receive KQB365 infusion weekly alone, in combination with cetuximab, or in combination with oral KQB198. * Visit the clinic about 9 times in the first 6 weeks, and then once every week after that.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
