7 Clinical Trials for Various Conditions
Protocol 777-CLP-32 is the treatment and survival continuation protocol of Biomed 777-CLP-29, and will continue to compare combined hormonal therapy using the experimental aromatase inhibitor (AI) atamestane combined with the FDA-approved anti-estrogen toremifene (Fareston®), to the single agent FDA-approved aromatase inhibitor letrozole (Femara®) for the treatment of advanced breast cancer. The purpose of this study is to determine whether maximal estrogen suppression achieved via the combination of atamestane, plus toremifene (Fareston®), is more effective than letrozole (Femara®) in delaying the growth of breast cancer.
The purpose of this study is to determine whether maximal estrogen suppression achieved via the combination of an experimental drug, atamestane, plus an FDA-approved drug, toremifene (Fareston®), is more effective than another approved drug, letrozole (Femara®), in delaying the growth of breast cancer, and whether the side effects of the combined hormonal therapy are different from the side effects of letrozole.
The purpose of this study is to determine whether the first line combination hormonal therapy of an experimental drug, atamestane, plus an FDA-approved drug, toremifene (Fareston®), is more effective than another approved drug, letrozole (Femara®), in delaying the growth of breast cancer in postmenopausal patients with locally advanced or metastatic breast cancer, and whether the side effects of the combination are different from the side effects of letrozole.
The purpose of this study is to examine the feasibility and preliminary efficacy of a psychosocial eHealth intervention designed to improve hormone therapy adherence among Hispanic/Latinx women with breast cancer. Our proposed secondary outcomes are health-related quality of life and self-efficacy in managing hormone therapy side effects. The intervention components include breast cancer knowledge, hormone/endocrine therapy knowledge, stress awareness and management, social support, and enhanced communication and intimacy skills. The intervention will be delivered via a Smartphone application over a 12-week period. All participants will receive the intervention application (described below). Aside from using the Smartphone application for the recommended 12 weeks, participation in this study includes three assessments: baseline (at the beginning of the research study), 6-week follow-up, and 12-week follow-up.
The purpose of this study is to examine the efficacy of a psychosocial eHealth intervention on the proposed primary outcomes, hormone therapy adherence and health related quality of life (HRQoL), in breast cancer survivors. The intervention components include mindfulness-based stress reduction, breast cancer knowledge, stress awareness and management, social support, and enhanced communication. The intervention will be delivered via an online application over an 8-week period. Participants are randomized into either an intervention application (described above) or a control application (health information and general health promotion strategies). Aside from having access to the online application for the recommended 8 weeks with weekly online focus groups, participation in this study includes four assessments: baseline (at the beginning of the research study), post-intervention (8 weeks after baseline), a 6-month follow-up and a 12-month follow-up.
This randomized phase II trial studies how well metformin hydrochloride and aspirin work in treating patients with hormone-dependent prostate cancer that has progressed after surgery or radiation therapy. Metformin hydrochloride and aspirin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving metformin hydrochloride and aspirin together can slow the growth of prostate cancer.
This multi-center study will evaluate whether thalidomide can improve the effectiveness of the drugs leuprolide or goserelin in treating testosterone-dependent prostate cancer. Leuprolide and goserelin-both approved to treat prostate cancer-reduce testosterone production, which, in most patients, reduces the size of the tumor. Thalidomide, a drug used for many years to treat leprosy, blocks the growth of blood vessels that may be important to disease progression. Patients 18 years or older with testosterone-dependent prostate cancer that has persisted or recurred after having had surgery, radiation therapy, or cryosurgery, but whose disease has not metastasized (spread beyond the prostate) may be eligible for this study. Candidates are screened with a medical history and physical examination, including blood tests, bone and computed tomography (CT) scans or other imaging studies. Study participants are randomly assigned to one of two treatment groups. One group receives leuprolide or goserelin followed by thalidomide; the other receives leuprolide or goserelin followed by placebo (a look-alike pill with no active ingredients). Patients in both groups receive an injection of leuprolide or goserelin once a month for 6 months. After that time they take four capsules of either thalidomide or placebo once a day and remain on the drug until their prostate-specific antigen (PSA) level returns to what it was before beginning leuprolide or goserelin or to 5 nanograms per liter, whichever is lower.(PSA is a protein secreted by the prostate gland. Monitoring changes in levels of this protein can help evaluate tumor progression). At this point the entire procedure begins again, starting with leuprolide or goserelin treatment, but the experimental drug is switched; patients originally treated with thalidomide are crossed over to placebo, and patients originally treated with placebo are crossed over to thalidomide. Patients are monitored periodically with the following tests and procedures: Medical histories and physical examinations. Blood and urine tests to monitor thalidomide and PSA levels, the response to treatment, and routine laboratory values (e.g., cell counts and kidney and liver function). Computed tomography (CT) and bone scans, and possibly other imaging tests to assess the tumor. Electromyography (EMG) and nerve conduction studies, as needed. For electromyography, a thin needle is inserted into a few muscles and the patient is asked to relax or to contract the muscles.
