ZurichAges 18 years+ - NCT07154043Recruiting
Comparing compression pump vs. massage for arm swelling
This study compares two therapies for breast cancer-related arm swelling (lymphedema): one uses a machine that pumps air around your arm (intermittent pneumatic compression, or IPC), and the other is a special type of massage (manual lymph drainage, or MLD). The goal is to see if the machine works as well as or better than massage for reducing swelling.
DenizliAges 18–65 - NCT06990659Recruiting
Outpatient vs. Inpatient Liver Cancer Treatment Study
This study compares having your liver cancer treatment (TACE or TARE) as an outpatient versus staying in the hospital overnight. It's for people with primary liver cancer whose liver and kidney function are good enough and who can safely go home the same day with support.
AmiensAges 18 years+ - NCT04317534RecruitingPhase 2
Pembrolizumab after lung cancer surgery versus observation
This trial tests whether pembrolizumab (an immunotherapy drug) given after complete surgery can lower the chance that early-stage lung cancer comes back. You’ll be compared to standard follow-up without extra treatment to see if the drug helps more people stay cancer-free.
Tampa, FloridaAges 18 years+ - NCT06310330Recruiting
Heart monitoring study for breast cancer patients
This study uses heart ultrasound (echocardiogram) to find early signs of heart damage from breast cancer treatment. It aims to better protect your heart during and after therapy.
TrondheimAges 18 years+ - NCT04389281RecruitingPhase 1
X-ray light-activated therapy for hard-to-treat skin tumors
This early-phase study tests an X-ray–activated medicine that is delivered directly into selected tumors to help control cancer that has not responded to standard treatments. If the injected area can be treated safely, it may shrink or slow the tumor and improve local control.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05672108RecruitingPhase 2
Chemo delivered into lung tumors using a catheter
This trial studies a treatment that delivers chemotherapy directly to lung tumors by placing a catheter into lung blood vessels. It may help people with lung cancer or lung metastases that are growing despite standard treatment, or who cannot tolerate it.
Duarte, CaliforniaAges 18 years+ - NCT07454642RecruitingPhase 1
AVA6103 for advanced FAP-positive solid tumors
This trial tests a new drug called AVA6103 for certain advanced cancers that show a protein called FAP. It is for people who have already tried other treatments or cannot take them, and aims to see if the drug is safe and helps shrink tumors.
