Liposomal bupivacaine during robotic throat surgery
This study gives a pain-relief medicine (bupivacaine in a slow-release form) during transoral robotic throat surgery. It aims to see if it improves comfort and pain control around the time of surgery.
Danville, PennsylvaniaAges 18 years+ - NCT05865002RecruitingPhase 1
Safety and drug test for AUR107 in advanced cancers
This early-phase study tests whether AUR107 is safe and may help shrink or control advanced solid tumors that have come back or progressed. You may be considered if standard treatments no longer work and you meet specific blood, organ, and health requirements.
Vijayawada, Andhra PradeshAges 18 years+ - NCT05865743RecruitingPhase 3
Antibiotic cloth before surgery to prevent esophagus infection
This Phase 3 trial tests whether using an antibiotic decolonization treatment around the time of esophagus surgery can reduce serious infections afterward. It may help you lower the risk of postoperative infectious complications after curative esophagectomy or esophagus reconstruction.

Blood test to predict cancer coming back after liver transplant
This study uses a blood test (looking at sugars in the blood) to help predict whether liver cancer will come back after a liver transplant. It may help doctors monitor you more accurately and earlier if cancer returns.
GhentAges 18 years+ - NCT05867966Recruiting
Testing a hypnosis-based program for symptom clusters in cancer
This trial studies whether a hypnosis-based approach can help reduce a selected set of troubling symptoms in people who have finished treatment for certain early-stage (non-metastatic) cancers. It aims to understand which symptom patterns improve and how well the intervention works.
LiègeAges 18 years+ - NCT05869474Recruiting
Iodine seed implant plus chemotherapy for metastatic pancreatic cancer
This trial studies whether placing iodine-125 radioactive seeds during a procedure, along with chemotherapy, can improve outcomes for people with pancreatic cancer that has spread to other organs. It aims to test a treatment that targets the tumor area while systemic chemotherapy works throughout the body.
