The city of Seattle, Washington, currently has 239 active clinical trials seeking participants for Cancer research studies.
Testing the Addition of Stereotactic Radiation Therapy With Immune Therapy for the Treatment of Patients With Unresectable or Metastatic Renal Cell Cancer, SAMURAI Trial
Recruiting
This phase II trial tests whether the addition of radiation to the primary tumor, typically given with stereotactic ablative radiation therapy (SABR), in combination with standard of care immunotherapy improves outcomes in patients with renal cell cancer that is not recommended for surgery and has spread from where it first started (primary site) to other places in the body (metastatic). Radiation therapy uses high energy photons to kill tumor cells and shrink tumors. Stereotactic body radiation... Read More

Testing the Use of Ado-Trastuzumab Emtansine Compared to the Usual Treatment (Chemotherapy With Docetaxel Plus Trastuzumab) or Trastuzumab Deruxtecan for Recurrent, Metastatic, or Unresectable HER2-Expressing Salivary Gland Cancers
Recruiting
This phase II trial compares the effect of usual treatment of docetaxel chemotherapy plus trastuzumab, to ado-emtansine (T-DM1) in patients with HER2-postive salivary gland cancer that has come back (recurrent), that has spread from where it first started (primary site) to other places in the body, or cannot be removed by surgery (unresectable). This trial is also testing how well trastuzumab deruxtecan works in treating patients with HER2-low recurrent or metastatic salivary gland cancer. Trast... Read More

Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With High Risk Prostate Cancer
Recruiting
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation preve... Read More

A Digital Health Intervention to Improve Symptoms and Physical Activity During Breast Radiation
Recruiting
This clinical trial evaluates a digital health intervention for improving symptoms and physical activity among patients with breast cancer undergoing radiation. Cancer-related fatigue is common and strongly associated with quality of life during and after treatment. Increasing emphasis on early symptom detection and management has prompted initiatives to collect patient-reported fatigue from all patients during treatment. Mind-body interventions including physical activity and yoga are recommend... Read More

Study of Novel Treatment Combinations in Patients With Lung Cancer
Recruiting
The goal of this platform clinical trial is to test how well novel treatment combinations work in participants with lung cancer. Substudy-01 will compare the different novel combinations versus standard of care in participants with metastatic (cancer that has spread) non-small-cell lung cancer (NSCLC) who have not been treated before. Substudy-02 will compare the different novel combination versus standard of care in participants with cancer that has progressed after receiving previous treatment... Read More

Sequential Testosterone and Enzalutamide Prevents Unfavorable Progression
Recruiting
Asymptomatic men without pain due to prostate cancer progressing with metastatic CRPC after treatment with combination or sequential ADT + Abi will be treated on a randomized, open label study to determine if sequential treatment with high dose T and Enza will improve primary and secondary objectives vs. continuous Enza as standard therapy.

Effect of HSD3B1 (1245C) Gene Mutation on Treatment of Stage I-III Breast Cancer
Recruiting
This stage IV trial examines how a mutation in HSD3B1 (1245C) gene affects treatment of stage I-III breast cancer. This trial may help researchers determine if mutations in HSD3B1 decreases the efficacy of aromatase inhibitor therapy such as letrozole. Letrozole may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Recruiting
This is a Phase III, randomised, open-label, multicentre, global study assessing the efficacy and safety of adjuvant Dato-DXd in combination with rilvegostomig compared with SoC, after complete surgical resection (R0) in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive, as determined by the Sponsor-designated ctDNA assay, or have at least one high-risk pathological feature.

The SISTER study is a randomized trial, looking at various modalities of social support for Black patients undergoing treatment for endometrial cancer. There are three study arms: group support, 1:1 peer support, and enhanced usual care. The primary outcome is treatment completion, and the secondary outcome is social isolation.

High Dose Testosterone for ATM, CDK12 or CHEK2 Altered Prostate Cancers
Recruiting
This study will determine whether the presence of DNA repair deficiency in the form of alterations in the genes ATM, CDK12 or CHEK2 predicts for a high likelihood of responding to the use of intermittent high dose testosterone. This therapy may result in responses in tumors which are genetically unstable because of DNA repair deficiency and this is a prospective study to test that hypothesis

Study of Radiation Therapy Followed by Atezolizumab in Stage II or III Non-small Cell Lung Cancer Patients
Recruiting
This phase II trial studies the side effects of radiation therapy followed by atezolizumab in treating patients with stage II or III non-small cell lung cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more cancer cells and have fewer side effects. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to g... Read More
