There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In this study, the investigators will evaluate the immunogenicity of a quadrivalent conjugate meningococcal vaccine in healthy, plateletpheresis donors.
This is a multicenter, Phase 2a, open-label, 2-part study to investigate the safety, tolerability, and anti-tumor activity of ZW25 (zanidatamab) in combination with palbociclib plus fulvestrant. Eligible patients include those with locally advanced (unresectable) and/or metastatic human epidermal growth factor receptor 2 (HER2)-positive, hormone receptor (HR)-positive breast cancer.
This study will evaluate the safety and efficacy of a switch to MK-8591A (a fixed dose combination of doravirine and islatravir) in human immunodeficiency virus -1 (HIV-1)-infected participants virologically suppressed on a regimen of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). The primary hypothesis is that a switch to MK-8591A will be non-inferior to continued treatment with BIC/FTC/TAF as assessed by the proportion of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48. Participants who benefit from their assigned intervention (as determined by investigator) will be able to continue treatment through a 24-week study extension.
This study will evaluate the safety and efficacy of a switch to MK-8591A (a fixed dose combination of doravirine and islatravir) in human immunodeficiency virus -1 (HIV-1)-infected participants virologically suppressed on a protocol-specified background antiretroviral regimen. The primary hypothesis is that a switch to MK-8591A will be non-inferior to continued treatment with baseline antiretroviral therapy (ART) as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48.
The purpose of this study is to assess the efficacy, safety, tolerability and pharmacokinetics (PK) of flexible doses of tavapadon in participants with Parkinson's Disease.
The purpose of our study is to determine if an association exists between the microbiome of those with rectal adenocarcinoma who are complete pathologic responders and those who have a partial or no response to neoadjuvant therapy.
This is an international, randomized, open-label, Phase 3 study designed to evaluate whether the potent and selective RET inhibitor, pralsetinib, improves outcomes when compared to a platinum chemotherapy-based regimen chosen by the Investigator from a list of standard of care treatments, as measured primarily by progression free survival (PFS), for participants with RET fusion-positive metastatic NSCLC who have not previously received systemic anticancer therapy for metastatic disease.
Peripheral neuropathy affects about 50% of the diabetic population and there is no treatment other than good blood glucose control, which is ineffective in subjects with type 2 diabetes. Part of the problem for the lack of an effective treatment is the inability to detect peripheral neuropathy in its early stage. The hypotheses to be addressed in the first phase of this study is that changes in cornea sensitivity (blinking and squinting) following addition of a hyperosmotic solution will provide a novel screening tool for early diagnosis of peripheral neuropathy. For the second phase of the study the investigators will examine the effect of fish oil treatment of diabetic subjects with neuropathy on corneal nerve density and sensitivity. Corneal nerves are the most highly innervated part of the human body with great sensitivity. The first phase will use this property and determine whether sensitivity is lost in diabetic patients with neuropathy. Preclinical studies have supported this hypothesis and now this will be tested in human subjects. Preclinical studies have also shown that treating diabetic rodents with fish oil improves nerve regeneration and outcome measures of peripheral in diabetic rodents. In the second phase the investigators will perform preliminary studies in human subjects with diabetic neuropathy and determine whether treating them with fish oil increases corneal nerve density and sensitivity.
Researchers at the Centers for American Indian and Alaska Native Health in the Colorado School of Public Health at the University of Colorado completed an intensive community-engaged process to rigorously adapt the Strengthening Families Program for Parents and Youth 10-14 for the cultural context of a Northern Plains reservation community, creating a program optimized for American Indian families, Thiwáhe Gluwáš'akapi (TG, sacred home in which family is made strong). This study will test the effectiveness of TG for delaying the onset of substance use among young adolescents. In response to requests from participating families and community partners to help address suicide risk among their youth, and based on preliminary evidence that the program may impact risk behaviors beyond substance use, the study will also test suicide risk outcomes among youth. Finally, in recognition of the potential for reciprocal influence on the adults participating in the program with their children, capitalizing on their motivation to make concomitant positive changes in their own lives, the current study will also examine effects on adult substance use. In summary, this study will test the effectiveness of TG for reducing risk for: (1) substance use among youth; (2) suicide risk among youth; and (3) substance abuse among adults.
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab plus concurrent chemoradiotherapy compared to placebo plus concurrent chemoradiotherapy in participants with locally advanced cervical cancer. The primary hypotheses are that pembrolizumab plus concurrent chemoradiotherapy is superior to placebo plus concurrent chemoradiotherapy with respect to progression-free survival and overall survival. Once the study objectives have been met or the study has ended, participants will be discontinued from this study and will be enrolled in an extension study to continue protocol-defined assessments and treatment.
