Cancer Clinical Trials in Seattle, WA

This study will test a drug called enfortumab vedotin in participants with a type of bladder cancer called non-muscle invasive bladder cancer (NMIBC). This study will also evaluate what the side effects are and if the drug works to treat NMIBC. A side effect is anything a drug does to your body besides treating your disease. In this study enfortumab vedotin will be put into the bladder using a catheter. A catheter is a thin tube that can be put into your bladder. Read Less

This phase II trial studies how well giving testosterone at levels higher than normally found in the body (supraphysiological) works to enhance chemotherapy treatment in patients with prostate cancer that has progressed despite being previously treated with androgen therapies and has spread from where it first started (prostate) to other places in the body (metastatic castration-resistant prostate cancer). In patients that have developed progressive cancer in spite of standard hormonal treatment, administering supraphysiological testosterone may result in regression of tumors by causing deoxyribonucleic acid (DNA) damage in tumor cells that have adapted to low testosterone conditions. Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Giving supraphysiological levels of testosterone and carboplatin or etoposide together may be an effective treatment for metastatic castration-resistant prostate cancer. Read Less

This Phase 1/2, open-label, multicenter study is conducted in patients with previously treated selected solid tumors, including non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), high-grade neuroendocrine cancer of any primary site, diffuse large B-cell lymphoma (DLBCL), and tumors with L-MYC or N-MYC amplification. Patients receive escalating doses of a GSPT1 molecular glue degrader MRT-2359 to determine safety, tolerability, maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of MRT-2359. Once the MTD and/or RP2D is identified, additional patients enroll to Phase 2 study, which includes molecular biomarkers stratification or selection, namely expression or amplification of L-MYC and N-MYC genes, hormone receptor positive (HR)-positive, human epidermal growth factor 2 (HER2)-negative breast cancer and prostate cancer.

This phase II trial studies the effect of DNA plasmid based vaccine (STEMVAC) in treating patients with patients with stage IB-III triple negative breast cancer. STEMVAC may wake up the immune system in patients who have had a diagnosis of triple negative breast cancer and have been treated. STEMVAC targets proteins that are expressed on breast cancer cells and works by boosting the immune system to recognize and destroy the invader cancer cell proteins that are causing the disease. The purpose of this trial is to test the immune system's response to STEMVAC. Read Less

This phase II trial tests whether CXCR1/2 inhibitor SX-682 (SX-682) with pembrolizumab works to treat patients with stage IIIC or IV non-small cell lung cancer that has spread to other parts of the body (metastatic) or that has come back (recurrent). SX-682 is a drug that binds to receptors on some types of immune and cancer cells, inhibiting signaling pathways, reducing inflammation, and allowing other types of immune cells to kill and eliminate cancer cells. Pembrolizumab is a monoclonal antibody that binds to a receptor called PD-1 that is found on the surface of T-cells (a type of immune cell), activating an immune response against tumor cells. Giving SX-682 in combination with pembrolizumab may be more effective at treating patients with metastatic or recurrent non-small cell lung cancer than giving these treatments alone. Read Less

This study will test the safety of a drug called SGN-BB228 in participants with melanoma and other solid tumors that are hard to treat or have spread through the body. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease. This study will have 3 parts. Parts A and B of the study will find out how much SGN-BB228 should be given to participants. Part C will use the information from Parts A and B to see if SGN-BB228 is safe and if it works to treat solid tumor cancers. Read Less

This study is being done to see if tucatinib with ado-trastuzumab emtansine (T-DM1) works better than T-DM1 alone to help patients who have a specific type of breast cancer called HER2 positive breast carcinoma. The breast cancer in this study is either metastatic (spread into other parts of the body) or cannot be removed completely with surgery. Patients in this study will be randomly assigned to get either tucatinib or placebo (a pill with no medicine). This is a blinded study, so neither patients nor their doctors will know whether a patient gets tucatinib or placebo. All patients in the study will get T-DM1, a drug that is often used to treat this cancer. Each treatment cycle lasts 21 days. Patients will swallow tucatinib pills or placebo pills two times every day. Patients will get T-DM1 injections from the study site staff on the first day of every cycle. Read Less

This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-1607 in patients with advanced malignancies. Read Less

This phase I/II trial studies the side effects of tozuleristide in imaging oral cavity squamous cell cancer and high-grade oral cavity dysplasia during surgery. Tozuleristide is an imaging agent that specifically binds to tumor cells. When exposed to near-infrared light, tozuleristide causes tumor cells to fluoresce (light up), so that surgeons may better distinguish tumor cells from healthy cells during surgery. Read Less

Under-representation of patients from racial/ethnic minority groups in cancer clinical trials is a major barrier to health equity. Black patients are significantly less likely to be enrolled in clinical trials compared with non-Hispanic White (White) patients although they carry a disproportionate burden of cancer mortality, the shortest survival rates, and are more likely to be diagnosed at later stages. Further, medical mistrust and lack of awareness and complexity of clinical trials are barriers that reduce the likelihood of clinical trial participation. The objective of this pilot study is to understand the effect of a culturally tailored decision aid (previously developed by our research team) on 1) medical mistrust, 2) patient knowledge about clinical trials, and 3) decision-making self-efficacy and determine the acceptability of the decision aid among Black patients currently or ever been diagnosed with cancer.

This study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer. Read Less

This is an international, multisite, open-label, Phase 1b/2 study, to confirm safety and efficacy of samuraciclib in combination with elacestrant in adult participants with metastatic or locally advanced Hormone Receptor (HR) positive and Human Epidermal Growth Factor Receptor (HER)2-negative breast cancer.
