Researchers are looking for patients with a specific type of lung cancer (non-small-cell lung cancer with EGFR PACC mutations) who have never received treatment for advanced disease. This study will test whether a new drug called firmonertinib works better and is safer than two existing drugs (osimertinib or afatinib) that doctors currently use. About 480 patients will be enrolled worldwide.
WHY IT MATTERSThis trial is actively recruiting patients with EGFR PACC mutations—a rare subset of lung cancer—and offers access to firmonertinib, a potentially more effective treatment option compared to standard first-line therapies.

Researchers are testing whether combining three cancer drugs—nivolumab, ipilimumab, and cabozantinib—can help treat rare cancers of the bladder, kidney, prostate, and other urinary system organs. This phase 2 trial is actively recruiting 314 patients to see if this drug combination works better than current treatments. The study is being run by the National Cancer Institute.
WHY IT MATTERSThis trial offers patients with rare genitourinary cancers (like collecting duct carcinoma, kidney medullary carcinoma, and rare bladder variants) access to a novel three-drug combination that may be more effective than standard treatments currently available.

Researchers are testing two cancer-fighting drugs called nivolumab and ipilimumab together to treat patients with rare types of cancer. These drugs help the body's immune system recognize and fight cancer cells. The trial is currently active but not accepting new patients at this time.
WHY IT MATTERSThis trial tests a combination immunotherapy approach across 50+ rare tumor types, offering potential treatment options for patients with uncommon cancers that have limited standard therapies available.

Researchers tested a cancer drug called osimertinib (AZD9291) in 19 patients with advanced cancers that have specific genetic changes in a gene called EGFR. The drug works by blocking a mutated protein that helps cancer cells grow. This trial is now complete and results have been posted.
WHY IT MATTERSThis trial provides evidence that osimertinib may work against cancers with EGFR mutations across different cancer types, potentially offering a treatment option for patients whose tumors have this specific genetic change.

Researchers are testing a drug called cabozantinib-s-malate to treat children and young adults with rare cancers, including sarcomas (muscle cancers), Wilms tumor (kidney cancer), and other solid tumors that have come back after treatment or didn't respond to initial therapy. The drug works by blocking proteins that help tumors grow and form new blood vessels. This phase II trial has enrolled 109 patients and is no longer recruiting new participants.
WHY IT MATTERSIf your child has a recurrent or treatment-resistant sarcoma, Wilms tumor, or other rare pediatric solid tumor, this completed trial data may help inform whether cabozantinib could be an option to discuss with their oncologist.

Researchers are testing a new genetic tool called RNA-Seq to help diagnose rare diseases in children and adults whose current genetic tests came back negative. This tool looks at how genes are turned on and off in cells, which can reveal problems that standard DNA testing misses. The study will first test the tool in healthy people and those with known genetic conditions, then use it to try to diagnose patients with undiagnosed rare diseases.
WHY IT MATTERSIf you have a child or family member with symptoms of a rare kidney or genetic disease but genetic testing hasn't found answers, this trial could offer a new diagnostic pathway that standard tests have missed.

Researchers at the National Institutes of Health are looking for up to 4,000 patients with rare metabolic disorders to study and treat. These are conditions where the body cannot properly break down certain substances because of missing or faulty proteins. Patients will receive exams and treatment, mostly as outpatients, though some may need to stay at the NIH Clinical Center for special tests.
WHY IT MATTERSThis trial offers patients with arterial calcification due to CD73 deficiency direct access to specialized NIH researchers and potential treatment options that may not be available elsewhere.

Researchers are looking for 60 people with hereditary multiple osteochondromas (a condition where benign bone tumors grow in multiple places on the body) to join a study. The study will measure how these tumors affect body shape, movement, and function in both children and adults. The goal is to better understand the disease and help doctors decide when surgery is needed.
WHY IT MATTERSThis trial is actively recruiting patients with hereditary multiple osteochondromas and could help establish better guidelines for when surgical treatment should happen, potentially improving outcomes for both pediatric and adult patients.

Researchers are testing a new drug called S-606001 to see if it can help adults with late-onset Pompe disease when added to their current enzyme replacement therapy (ERT) treatment. Pompe disease is a rare genetic condition where the body can't break down a type of sugar, causing muscle weakness over time. This study will check if the new drug is safe and if it helps patients feel better or move more easily. The trial is currently looking for 45 adult participants to join.
WHY IT MATTERSThis trial is actively recruiting adults with late-onset Pompe disease who are already on enzyme replacement therapy — eligible participants may be able to access an investigational add-on treatment that could potentially improve their muscle function.

Researchers across 7 European countries are working together to develop better ways to diagnose two rare kidney diseases: atypical hemolytic-uremic syndrome (aHUS) and C3 glomerulonephritis (C3G). This study is enrolling 180 people, including patients with these conditions and healthy volunteers, to test new diagnostic tools that could help doctors identify these diseases more quickly and accurately.
WHY IT MATTERSThis trial is developing improved diagnostic tests for aHUS and C3G, which could help patients get diagnosed faster and start treatment sooner—critical since these complement-mediated kidney diseases can cause permanent kidney damage if left untreated.

Researchers at the National Heart, Lung, and Blood Institute are looking for 5,000 people who have or might have diseases that affect their heart, blood vessels, or metabolism. Participants will have blood tests and heart function tests tailored to their specific condition. Both people with these conditions and healthy people can join to help scientists understand why some people develop heart disease.
WHY IT MATTERSThis large-scale study is actively recruiting and may help identify new risk factors for heart disease in people with rare metabolic, inflammatory, and genetic conditions like Li-Fraumeni Syndrome and cardiomyopathy.
