A Fluorescent Tumor Marking Agent, Tozuleristide, for Imaging Oral Cavity Squamous Cell Cancer and High-Grade Oral Cavity Dysplasia During Surgery
NCT05316688
Recruiting
This phase I/II trial studies the side effects of tozuleristide in imaging oral cavity squamous cell cancer and high-grade oral cavity dysplasia during surgery. Tozuleristide is an imaging agent that specifically binds to tumor cells. When exposed to near-infrared light, tozuleristide causes tumor cells to fluoresce (light up), so that surgeons may better distinguish tumor cells from healthy cells during surgery.

Assessing Minimal Residual Disease by Next- Generation Sequencing to Minimize Exposure in People With CLL or SLL Who Have Been Treated With Venetoclax
NCT04419519
Recruiting
This study will find out whether people with CLL or SLL who have received treatment with venetoclax, either alone or in combination with another drug, and who are found to be MRD-negative, can stop treatment with venetoclax and remain off-treatment for 12 months or more. The researchers will also see whether study participants remain MRD-negative after they stop treatment with venetoclax.
