NCT04583072
Introduction: Prostate cancer (PCa) is the most commonly detected cancer in men and is the second leading cause of cancer death. Differences in race and ethnicity have been shown to have differences in PCa incidence, detection, and outcomes. Current prostate cancer screening involves prostatic specific antigen (PSA) which is a nonspecific protein marker (aka kallikrein) that can often leads to unnecessary biopsies (up to 74% benign biopsies) and clinical overdiagnosis (with up to 22% clinically insignificant cancer). Recently more sophisticated tests have been developed for PCa screening in the United States such as the Prostate Health Index (PHI) and the 4k (kallikrein) score, as well as clinical models that use information from the patient clinical history. However, these tests utilize limited serum protein assays and none of the established screening protocols utilize genetic variables to help account for the likely inherited risks as seen in different ethnicities. A recent Swedish, prospective, population-based study, published in the Lancet Oncology, developed a unique multivariable biopsy outcome prediction model within a Nordic population of nearly 60,000 men. This model, the Stockholm3, which incorporated plasma protein markers, germline DNA SNPs as well as clinical variables, was shown to be capable of reducing the number of biopsies by 44% compared to PSA while maintaining adequate sensitivity for detection of PCa. It is unknown whether an approach developed in Sweden that incorporates protein markers, genetics, clinical variables, and genetic ancestry would be beneficial in a racially diverse cohort. Hypothesis: The investigators hypothesize that, a prospectively studied multiethnic cohort of men with the Stockholm3 test will identify unique and common risk factors that improve prostate cancer detection. Aim: To assess the performance of the Stockholm3 test as compared to PSA and to identify unique features associated with PCa in Black/African American (n=500), Asian (n=500), White/Caucasian Hispanic (n=500), and White/Caucasian Non-Hispanic (n=500) men. Methods: The investigators propose a prospectively identified cohort with participating institutions which have screened positive to undergo a prostate biopsy to have a retrospective analysis the Stockholm3 test and ancestry markers. Within this cohort the investigators will examine several predetermined risk factors to investigate their relationship to prostate cancer. This blood sample will be tested for quantitative levels of serum protein markers and DNA will be extracted and will be tested for germline mutations as defined by the Stockholm3 test and other ancestry informative markers. Results from the study will be presented in such a way that no individual information will be disclosed.
NCT03640325
Multisite Randomized Controlled Trial (RCT) testing the efficacy of the Promoting Resilience in Stress Management (PRISM) intervention among Adolescents and Young Adults receiving hematopoietic cell transplantation for hematology malignancy.
NCT05593432
The purpose of this study will be to evaluate efficacy and safety of Ruxolitinib cream in participants With Cutaneous Lichen Planus. This is randomized, double-blind, vehicle-controlled (DBVC) study with a DBVC period of 16 weeks followed by an open label period (OLE) period of 16 weeks.
NCT04094818
This study will analyze gene expression and other laboratory data from biological samples collected from participants with suspected respiratory, urinary, intra-abdominal, and/or skin \& soft tissue infections; or suspected sepsis of any cause.
NCT03973333
IMC-C103C is an immune mobilizing monoclonal T cell receptor against cancer (ImmTAC ®) designed for the treatment of cancers positive for the tumor-associated antigen MAGE-A4. This is a first-in-human trial designed to evaluate the safety and efficacy of IMC-C103C in adult patients who have the appropriate HLA-A2 tissue marker and whose cancer is positive for MAGE-A4.
NCT00285259
The purpose of this trial is to evaluate a CMV vaccine given to related donor/recipient pairs (donors prior to peripheral blood stem cell donation and CMV-seropositive recipients just before and after transplantation) and CMV-seropositive recipient-only subjects (related or unrelated) to determine incidence rates of CMV infection, disease, and other complications from immunosuppression and/or transplantation. The outcomes for the groups receiving CMV vaccine will be compared to the outcomes for the group that received the placebo vaccine to see if there is a clinical benefit. For this trial, donors and recipients must have matched HLA genotype (matched at 5/6 or 6/6 HLA loci).
NCT02432807

NCT02860039
This phase II randomized trial studies how well high dose flu vaccine works in treating children who have undergone done stem cell transplant. Higher dose flu vaccine may build a better immune response and may provide better protection against the flu than the standard vaccine.

NCT03733418
This ancillary study will determine if early administration of a single high-dose (540,000 IU) oral vitamin D3 (cholecalciferol) treatment improves 12-month global cognition and executive function as determined by comprehensive neuropsychological testing in 140 critically ill patients with Vitamin D deficiency at enrollment.
NCT03005327
This is a Phase 2 study with an initial 24-week Treatment Period and an Extension Phase. The primary objectives of this Phase 2 study are to determine the safety, tolerability, and dose selection of mavorixafor in participants with WHIM syndrome. Participants may continue treatment in an Extension Phase, if regionally applicable, until mavorixafor becomes available via an alternative mechanism (for example, drug is commercially available, an expanded access program, etc.) or until the study is terminated by the Sponsor for any reason.
NCT02270463
This is a non-randomized, open-label, multicenter, dose escalation study designed to determine the maximum tolerated dose (MTD) of SL-401 in adult patients with acute myeloid leukemia, and to evaluate the safety profile of SL-401 at the MTD.

There were three cohorts: * Cohort 1: Relapsed or refractory (R/R) extranodal NK/T cell lymphoma (ENKTL; nasal or non-nasal type) * Cohort 2: Other R/R mature T-cell neoplasms, limited to the following histologies: peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL), or anaplastic large-cell lymphoma (ALCL) * Cohort 3: R/R cutaneous T-cell lymphoma, limited to mycosis fungoides (MF) or Sèzary syndrome (SS) Study procedures included a Screening phase (up to 35 days); Treatment phase (until disease progression, intolerable toxicity, or withdrawal of informed consent, whichever occurs first); Safety Follow-up phase (up to 90 days following last study treatment for all adverse events (AEs) and serious adverse events (SAEs)); and Survival follow-up phase (duration varying by participant).
NCT03191786
This Phase III, global, multicenter, open-label, randomized, controlled study will evaluate the efficacy and safety of atezolizumab (an anti-programmed death-ligand 1 \[anti-PD-L1\] antibody) compared with a single agent chemotherapy regimen by investigator choice (vinorelbine or gemcitabine) in treatment-naïve participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) who are deemed unsuitable for any platinum-doublet chemotherapy due to poor performance status (Eastern Cooperative Oncology Group \[ECOG\] performance status of 2-3).
