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

300

The 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

300

Non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Trials focus on targeted therapies, immunotherapy, and combination regimens.

Prostate Cancer

300

The most common cancer in men in the U.S. Trials test hormonal, radiation, surgical, and novel therapies across risk groups.

Colorectal Cancer

300

Cancer of the colon or rectum. Trials span screening, adjuvant therapy, and metastatic disease.

Pancreatic Cancer

300

One of the most aggressive cancers. Clinical trials are often the most direct path to access promising new therapies.

Ovarian Cancer

300

Epithelial ovarian cancer and related gynecologic malignancies. Trials focus on PARP inhibitors, immunotherapy, and maintenance strategies.

Leukemia

300

Cancers of the blood and bone marrow. Clinical trial participation is historically higher for leukemia than most solid tumors.

Lymphoma

300

Hodgkin and non-Hodgkin lymphoma subtypes. Trials explore CAR-T therapy, bispecific antibodies, and relapsed/refractory regimens.

Brain Cancer

300

Primary brain tumors including glioblastoma multiforme (GBM), lower-grade gliomas, and other CNS malignancies.

Head and Neck Cancer

300

Cancers 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

300

Largely HPV-driven. Trials span prevention, early-stage (often curable with surgery + radiation), and advanced/metastatic disease.

Sarcoma

289

Rare cancers of bone and soft tissue. Many subtypes with distinct biology. Specialized sarcoma centers often run trials unavailable elsewhere.

Multiple Myeloma

265

Plasma cell malignancy. Trials test CAR-T, bispecific antibodies, and combination regimens in newly diagnosed and relapsed/refractory settings.

Melanoma

251

The most serious form of skin cancer. Trials span adjuvant, neoadjuvant, and metastatic disease — with major advances in immunotherapy.

Stomach Cancer

211

Gastric adenocarcinoma. Trials test perioperative chemo-immunotherapy, HER2-targeted agents, and novel therapies for advanced disease.

Kidney Cancer

205

Renal cell carcinoma (RCC) and related kidney malignancies.

Bladder Cancer

199

Urothelial carcinoma of the bladder. Non-muscle-invasive and muscle-invasive disease both have active trial programs.

Liver Cancer

196

Hepatocellular carcinoma (HCC) and related primary liver malignancies.

Endometrial Cancer

188

The most common gynecologic cancer in the U.S. Trials focus on hormonally driven subtypes, MSI-H/dMMR immunotherapy, and advanced disease.

Esophageal Cancer

182

Squamous cell carcinoma and adenocarcinoma of the esophagus. Trials explore combination chemoradiation, immunotherapy, and perioperative regimens.

Thyroid Cancer

81

Papillary, follicular, medullary, and anaplastic thyroid carcinomas. Most are highly curable; trials focus on advanced and recurrent disease.

Testicular Cancer

29

Highly 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.
