Columbus, OH Paid Clinical Trials

The investigators will follow probability-based cohorts of adult non-medical marijuana users (N=1,500; ages 21+) and susceptible adolescents and young adults (AYA) users (N=1,000; ages 15-20) over four years. The investigators will use a prospective survey to collect marijuana use information and will conduct volumetric choice experiments (VCEs) where participants choose quantities to purchase among three legal product prototypes: flower, edible, and concentrate; and one illegal flower product, under simulated retail marijuana tax structures. The presentation of edibles and concentrates will change over time to capture the range of product varieties in the market and to accommodate new products and characteristics as they evolve. Choice experiments including VCEs use a series of manipulations as a measurement device to elicit preferences for products and consumption. Therefore, the experimental design is within-subjects with repeated measures, which allow for causal identifications of the impact of design attributes (e.g., tax bases and rates) on preference and consumption outcomes. The attributes and levels are selected to reflect THC levels in the market, existing (weight, price, tiered price by forms) and novel (potency) tax bases, existing (10%-40% of retail price or equivalent in other bases) and potential (high 60% and 80% of retail prices or equivalent) tax rates, and price distribution for each product. Price distribution levels (5 to 95 percentiles) will come from our price data collection and will be updated over time and vary by participants' state and locality of residence. Before the experiment, study personnel will instruct participants 1) how to answer the choice experiment question, including considering their weekly expenditures when answering VCE questions; 2) that there is no access to other products, no stockpiling, no selling or giving away products to others, etc., to ensure that participants choose products that reflect their usual purchase patterns for self-use; 3) that there are no right or wrong responses. Study personnel will instruct participants to answer all questions honestly, thoughtfully, and to the best of their understanding as if they were actually in this situation, to reduce hypothetical bias; 4) that there may be potential costs or issues associated with purchasing illegal products, including risks of penalties, undefined potency, possible contamination, and inconsistent product quality; and 5) that participants should keep their weekly budget in mind when making purchase choices of the products. In VCEs, the investigators will manipulate THC levels, tax rates and bases, and price levels. Participants will be asked to answer the following: "Imagine these are the marijuana products that you (participants) can purchase for non-medical use, how many of each product would you (participants) most likely buy next time?" Participants can choose more than one product, and as they choose quantities, the total balance will be displayed. To make the tasks easier, study personnel will 1) set a warning to inform participants if their reported budget exceeds their weekly budget for spending; 2) provide a dropdown list for quantities or, if they would like more units than the listed, they can fill in a number; and 3) all products are described as high-quality to allow for a comparison of prices. Half of the participants will be randomized to see itemized pre-tax tag price, excise taxes, and sales taxes, as requested in some states (e.g., Illinois); the other half will be randomized to see only prices that are inclusive of excise taxes. This will allow us to whether excise taxes are more effective when applied at checkout compared to hidden in the tag prices. Read Less

This pilot clinical trial studies transoral robotic surgery (TORS) in treating patients with benign or malignant tumors of the head and neck. TORS is a less invasive type of surgery for head and neck cancer and may have fewer side effects and improve recovery Read Less

This phase II trial tests how well canakinumab works to prevent progression to cancer in patients with clonal cytopenias of unknown significance (CCUS). CCUS is a blood condition defined by a decrease in blood cells. Blood cells are composed of either red blood cells, white blood cells, or platelets. In patients with CCUS, blood counts have been low for a long period of time. Patients with CCUS also have a mutation in one of the genes that are responsible for helping blood cells develop. The combination of genetic mutations and low blood cell counts puts patients with CCUS at a higher risk to develop blood cancers in the future. This transformation from low blood cell counts to cancer may be caused by inflammation in the body. Canakinumab is a monoclonal antibody that may block inflammation in the body by targeting a specific antibody called the anti-human interleukin-1beta (IL-1beta). Read Less

This phase II trial tests how well tafasitamab and rituximab work for front-line treatment of patients with post-transplant lymphoproliferative disorder. Post-transplant lymphoproliferative disorder (PTLD) is the name for types of lymphoma that sometimes develop in people who have had a transplant. It can affect people who are taking medicines to suppress their immune system. Tafasitamab injection is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving the combination of tafasitamab and rituximab may work better in treating patients with post-transplant lymphoproliferative disorder. Read Less

The goal of this study is to determine the efficacy of the study drug olutasidenib to treat newly diagnosed pediatric and young adult patients with a high-grade glioma (HGG) harboring an IDH1 mutation. The main question the study aims to answer is whether the combination of olutasidenib and temozolomide (TMZ) can prolong the life of patients diagnosed with an IDH-mutant HGG. Read Less

The goal of this clinical trial is to test whether inclusion of cognitive behavioral therapy (CBT) for Uncertainty-Enhanced (CUE) with Lethal Means Counseling (LMC) is acceptable, feasible, and efficacious in addressing secure firearm storage and associated psychological constructs in active duty servicemembers. The clinical trial aims to: * Assess the preliminary efficacy of a LMC intervention, augmented with CUE, on firearm storage practices * Examine mechanisms through which CUE and LMC increase firearm storage practices * Assess credibility and acceptability of LMC Participants will complete: * One baseline visit * Two intervention sessions-CUE and LMC * Six brief surveys per day for 28 days using a mobile application * One mid-point survey and five follow-up surveys Read Less

This phase I trial tests the safety, side effects, and best dose of intraperitoneal oxaliplatin and fluorouracil in treating patients with colorectal cancer that has spread to the peritoneal cavity (peritoneal metastasis). Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill cancer cells. Fluorouracil stops cells from making DNA and it may kill cancer cells. Both oxaliplatin and fluorouracil are approved by the Food and Drug Administration to treat patients with colorectal cancer, however administration of these drugs directly into the area between the muscles and organs in the abdomen (intraperitoneal) for the treatment of peritoneal metastases is experimental. Giving oxaliplatin and fluorouracil directly into the peritoneal space may be a safe and effective way of treating patients with peritoneal metastases from colorectal cancer. Read Less

The proposed research is a feasibility pilot trial designed to optimize the remote collection dried blood spots (DBS) from a finger stick and the analysis of fatty acid from the DBS and to optimize the analysis of mitochondria activity (or energy metabolism) from peripheral blood mononuclear cells (PBMC) or white blood cell samples. Participants in this study will provide a blood sample from venous blood draw and finger sticks. One finger stick collection will be completed remotely using a DBS kit that is sent through the mail while the other finger stick collection will be completed at the research site. These samples will be use to optimize the method for measuring fatty acids and mitochondria function as well as measure other lipids, insulin, glucose and markers of inflammation using established protocols. Demographic, dietary, sleep, and physical activity information will be measured using questionnaires, while height and weight will be measured to calculate body mass index (BMI). Read Less

The goal of this observational trial is to compare the health history and motion capabilities of participants with low back pain disorders to participants with healthy spines. The main question\[s\] it aims to answer are to: 1. Primary outcomes of this research effort include composite measures that differentiate between control and patient populations, predict injury or reinjury risk, identify low back and neck pain patient phenotypes, and evaluate treatment effectiveness. 2. Secondary outcomes of this research effort include an assessment of wearable motion sensor accuracy, characterization of motion assessment utility, biopsychosocial profiling of control and low back and neck pain patient populations, and differentiation of sincere and insincere motion assessment efforts.
