Perivenous Dexamethasone Therapy: Examining Reduction of Inflammation After Thrombus Removal to Yield Benefit in Acute Femoropopliteal DVT
NCT04862468
Recruiting
This is a study of a medical procedure that utilizes a commercially available catheter (the Bullfrog® Micro-Infusion Device) to locally deliver a commercially available anti-inflammatory drug (dexamethasone sodium phosphate injection) around the deep veins after DVT recanalization, where DVT symptoms were present for up to 14 days prior to recanalization. The goal of the study is to see if local anti-inflammation helps prevent re-thrombosis of the blood vessel and improvement in symptoms for up... Read More

CAR-T Cells for HIV Infection
NCT04648046
Recruiting
This is a limited-center, open-label dose escalating phase I/IIa study of autologous T cells expressing LVgp120duoCAR molecules in people with HIV infection. It will follow a 3+3 design. Dose escalation decisions will be made when a minimum of three participants have completed the safety-evaluation period (45 days) at a given dose level. Cohort 1 will undergo infusion of a single low-dose regimen of LVgp120duoCAR-T cells. Cohort 2 will undergo non-ablative conditioning with cyclophosphamide, fol... Read More

A Study to Compare Blinatumomab Alone to Blinatumomab With Nivolumab in Patients Diagnosed With First Relapse B-Cell Acute Lymphoblastic Leukemia (B-ALL)
NCT04546399
Recruiting
This phase II trial studies the effect of nivolumab in combination with blinatumomab compared to blinatumomab alone in treating patients with B-cell acute lymphoblastic leukemia (B-ALL) that has come back (relapsed). Down syndrome patients with relapsed B-ALL are included in this study. Blinatumomab is an antibody, which is a protein that identifies and targets specific molecules in the body. Blinatumomab searches for and attaches itself to the cancer cell. Once attached, an immune response occu... Read More

Safety, Tolerability and PK of ATTO-1310 in Healthy Volunteers and Patients With Atopic Dermatitis and Patients With Chronic Pruritus
NCT06787586
Recruiting
The goal of this clinical trial is to assess the safety, tolerability, and pharmacokinetics of ATTO-1310 in healthy adults, patients with atopic dermatitis and patients with chronic pruritus. The main questions it aims to answer are: What medical problems do participants have when taking ATTO-1310? How long does ATTO-1310 stay in the body after dosing? Researchers will compare ATTO-1310 to a placebo (a look-alike substance that contains no drug). Participants will be dosed with ATTO-1310 or a... Read More

Avapritinib With Decitabine in Patients With SM-AHN
NCT06327685
Recruiting
Systemic mastocytosis with an associated hematologic neoplasm (SM-AHN) is a challenging disease to treat. Targeted KIT inhibitors have been approved for this indication based on their ability to control the mastocytosis portion of the disease, but patients frequently experience progression of the concomitant myeloid malignancy (i.e. the AHN). Using a combination approach to treat both aspects of the disease has the potential to provide enhanced disease control; however, overlapping toxicity is a... Read More

Prevention of Frailty With Fisetin and Exercise in Breast Cancer Survivors
NCT06113016
Recruiting
This phase II trial tests how well fisetin and exercise works in preventing frailty in breast cancer survivors. Fisetin is a natural substance found in strawberries and other foods and is available as a nutritional supplement. Nutritional supplements may be useful in eliminating cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and c... Read More
