Clinical Trials
Cancer clinical trials — recruiting now
We aggregate active recruiting oncology clinical trials from ClinicalTrials.gov — the U.S. National Library of Medicine registry. Browse by cancer type, then filter by state.
Showing 5,396 trials across 22 cancer types. Data last refreshed .
Breast Cancer
300The most common cancer in women in the U.S. Clinical trials test new therapies for early-stage, locally advanced, and metastatic breast cancer.
Lung Cancer
300Non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Trials focus on targeted therapies, immunotherapy, and combination regimens.
Prostate Cancer
300The most common cancer in men in the U.S. Trials test hormonal, radiation, surgical, and novel therapies across risk groups.
Colorectal Cancer
300Cancer of the colon or rectum. Trials span screening, adjuvant therapy, and metastatic disease.
Pancreatic Cancer
300One of the most aggressive cancers. Clinical trials are often the most direct path to access promising new therapies.
Ovarian Cancer
300Epithelial ovarian cancer and related gynecologic malignancies. Trials focus on PARP inhibitors, immunotherapy, and maintenance strategies.
Leukemia
300Cancers of the blood and bone marrow. Clinical trial participation is historically higher for leukemia than most solid tumors.
Lymphoma
300Hodgkin and non-Hodgkin lymphoma subtypes. Trials explore CAR-T therapy, bispecific antibodies, and relapsed/refractory regimens.
Brain Cancer
300Primary brain tumors including glioblastoma multiforme (GBM), lower-grade gliomas, and other CNS malignancies.
Head and Neck Cancer
300Cancers of the oral cavity, pharynx, larynx, and salivary glands. HPV-driven and smoking-driven subtypes behave differently; trials often stratify on HPV status.
Cervical Cancer
300Largely HPV-driven. Trials span prevention, early-stage (often curable with surgery + radiation), and advanced/metastatic disease.
Sarcoma
289Rare cancers of bone and soft tissue. Many subtypes with distinct biology. Specialized sarcoma centers often run trials unavailable elsewhere.
Multiple Myeloma
265Plasma cell malignancy. Trials test CAR-T, bispecific antibodies, and combination regimens in newly diagnosed and relapsed/refractory settings.
Melanoma
251The most serious form of skin cancer. Trials span adjuvant, neoadjuvant, and metastatic disease — with major advances in immunotherapy.
Stomach Cancer
211Gastric adenocarcinoma. Trials test perioperative chemo-immunotherapy, HER2-targeted agents, and novel therapies for advanced disease.
Kidney Cancer
205Renal cell carcinoma (RCC) and related kidney malignancies.
Bladder Cancer
199Urothelial carcinoma of the bladder. Non-muscle-invasive and muscle-invasive disease both have active trial programs.
Liver Cancer
196Hepatocellular carcinoma (HCC) and related primary liver malignancies.
Endometrial Cancer
188The most common gynecologic cancer in the U.S. Trials focus on hormonally driven subtypes, MSI-H/dMMR immunotherapy, and advanced disease.
Esophageal Cancer
182Squamous cell carcinoma and adenocarcinoma of the esophagus. Trials explore combination chemoradiation, immunotherapy, and perioperative regimens.
Thyroid Cancer
81Papillary, follicular, medullary, and anaplastic thyroid carcinomas. Most are highly curable; trials focus on advanced and recurrent disease.
Testicular Cancer
29Highly curable germ cell tumors. Trials focus on reducing toxicity of curative therapy and treating relapsed/refractory disease.
About this data: Every trial on this site is sourced directly from ClinicalTrials.gov — the U.S. National Library of Medicine registry of public and privately supported clinical studies. We fetch the data periodically and link back to the canonical ClinicalTrials.gov study page for the most current information.
This is not medical advice. Eligibility for a clinical trial is determined by the trial's investigators. Contact the trial site directly or speak with your oncologist before enrolling.
