ClinConnect Summary

This clinical trial is studying a new medication called ST-1898, which is designed to help patients with advanced melanoma that cannot be surgically removed or has spread to other parts of the body. The main goals of the trial are to see how safe and well-tolerated ST-1898 is, determine the right dose for future studies, and evaluate how effective it is at treating melanoma. The trial is open to adults aged 18 and older who have been diagnosed with stage III or IV melanoma and whose cancer has continued to grow despite standard treatments.

Participants in this trial can expect to receive the ST-1898 tablets and will be closely monitored by healthcare professionals for any side effects or changes in their condition. To qualify, participants need to have a life expectancy of at least three months, be in relatively good health, and have measurable tumor growth. It's important to note that certain health conditions or recent treatments may exclude individuals from participating, so potential candidates should discuss their specific situations with their doctors. Overall, this trial aims to find new treatment options for people facing challenging stages of melanoma.
