ClinConnect Summary

This clinical trial is exploring a new treatment for patients with advanced cancers, specifically looking at how safe and effective a special type of engineered red blood cells combined with cancer-fighting drugs (called checkpoint inhibitors) can be. The researchers hope to find out if this new therapy can help patients whose cancers have not responded to standard treatments.

To participate in this trial, individuals must be between 18 and 75 years old and have been diagnosed with advanced solid tumors or certain types of blood cancers. They should have already received at least one treatment for their cancer and have measurable disease. Participants can expect to receive this novel therapy and be closely monitored for any side effects or benefits. It's important to note that not everyone will qualify; certain health conditions or recent treatments may exclude some individuals from participating. If you or a loved one are interested, speaking with a healthcare provider can provide more personalized information.
