ClinConnect Summary

This clinical trial, called NP-G2-044, is investigating a new treatment for patients with advanced or metastatic solid tumor cancers. The study aims to assess how safe and effective the drug NP-G2-044 is when used alone or in combination with another treatment known as anti-PD-1 therapy. They are looking for participants aged 18 and older who have solid tumors that standard treatments have not helped. To qualify, patients should have a good level of health with a life expectancy of more than six months, and they should be able to take capsules or tablets.

Those interested in participating can expect to receive NP-G2-044 continuously, either by itself or along with anti-PD-1 therapy, depending on their specific cancer type and treatment history. The trial is currently recruiting, and participants will be closely monitored for how well they tolerate the treatment and how their cancer responds. It’s important to note that some patients may not be eligible if they have certain health conditions, have recently received other cancer treatments, or are pregnant or breastfeeding. If you or a loved one are considering this trial, you should discuss it with a healthcare provider to understand more about the potential benefits and risks.
