NCT01882803
This was a Phase 2 clinical trial to evaluate the safety and efficacy of duvelisib as a monotherapy in participants with indolent non-Hodgkin lymphoma (iNHL) (follicular lymphoma \[FL\], marginal zone lymphoma, or small lymphocytic lymphoma) that was refractory to rituximab and to either chemotherapy or radioimmunotherapy (RIT).
NCT04964323
The primary objective of this study is to understand and characterize the health-related quality of life (HRQoL) and disease burden of adult participants with PK deficiency receiving routine clinical care. This study is an observational (i.e., noninterventional), longitudinal, multicenter, global registry for participants with PK deficiency, a rare nonspherocytic hemolytic anemia. This study will be open for enrollment for 2 years and all enrolled participants will be followed prospectively for up to 96 weeks. Data will be collected from participants who have provided informed consent and authorization pursuant to applicable laws and regulations.
NCT05839899
Patients who seek medication abortion early in pregnancy may have an ultrasound that does not show a pregnancy in the uterus. This is known as a "pregnancy of unknown location". These patients most likely have a pregnancy in the uterus that is too early to be seen on ultrasound, but it is possible that the pregnancy is not seen inside the uterus because it is outside of the uterus, known as an ectopic pregnancy. Patients with ectopic pregnancies are at risk for serious complications, and the medications used for medication abortion may not end an ectopic pregnancy. Currently, at Planned Parenthood League of Massachusetts (PPLM), patients seeking medication abortion, including some patients with a pregnancy of unknown location, are given mifepristone to begin the medication abortion at the clinic and then one dose of misoprostol to take at home to cause the pregnancy to pass. However, research suggests that a second dose of misoprostol leads to a higher rate of completed abortion for certain patients. This research is being conducted to learn if two doses of the at-home misoprostol during the medication abortion process leads to a higher rate of completed abortion for patients with pregnancy of unknown location. In this study, all participants will receive mifepristone as they normally would. Then, participants will be randomly assigned to receive either one dose of misoprostol or two doses of misoprostol.
NCT03334253
Study Objectives The objectives for this randomized trial are: 1. To determine the efficacy of daily low-dose atropine (0.01%) for slowing myopia progression over a two-year treatment period in children aged 5 to less than 13 years (Primary Outcome On-Treatment). 2. To determine the efficacy of atropine treatment on myopia progression 6 months following cessation of low-dose atropine treatment (Secondary Outcome Off-Treatment). Synopsis of Study Design The current study is designed as an efficacy study, making effort to maximize adherence to treatment group assignments. After a run-in phase during which all participants are treated with daily artificial tear eyedrops for 2-4 weeks (and glasses are updated if required) to assess their ability to adhere to daily eye drops, participants are randomly assigned to daily atropine or placebo for 24 months, followed by 6 months off treatment.
NCT03321734
Intermittent Hypoxia and Caffeine in Infants Born Preterm (ICAF) Our proposal will address the critical question: is persisting intermittent hypoxia (IH) in preterm infants associated with biochemical, structural, or functional injury, and is this injury attenuated with extended caffeine treatment? The investigators will study the effects of caffeine on IH in 220 preterm infants born at ≤30 weeks + 6 days gestation. Infants who are currently being treated with routine caffeine, and who meet eligibility criteria, will be enrolled between 32 weeks + 0 days and 36 weeks + 6 days PMA. At enrollment, infants will be started on continuous pulse oximeter recording of O2 saturation and heart rate. If, based on standard clinical criteria, the last dose of routine caffeine is given on or before the day the infant is 36 weeks + 5 days PMA, then on the day following their last dose of routine caffeine treatment, infants will be randomized (110/group) to extended caffeine treatment or placebo. Randomized infants should begin receiving study drug (i.e. 5 mg/kg/of caffeine base, or equal volume of placebo) on the day of randomization, but no later than the third calendar day following the last dose of routine caffeine. Prior to 36 weeks + 0 days PMA, study drug will be given once daily (i.e. 5mg/kg/day) and beginning at 36 weeks + 0 days PMA, study drug will be given twice daily (i.e. 10 mg/kg/day). The last dose of study drug will be given at 42 weeks + 6 days PMA. Pulse oximeter recordings will continue 1 additional week after discontinuing study drug. Two caffeine levels will be obtained, the 1st at one week after beginning study drug, and the 2nd at a target date of 40 weeks + 0 days PMA, but no later than the last day of study drug, whether in hospital or at home. Inflammatory biomarkers will be measured at study enrollment and again at 38 weeks + 0 days PMA, or within 2 calendar days prior to hospital discharge, whichever comes first. Quantitative MRI/MRS should be obtained between study enrollment and 3 calendar days after starting study drug and again at a target date of 43 weeks + 0 days, but no later than 46 weeks + 6 days PMA.
NCT04144738
The primary objective of this study is to assess the sensitivity for colorectal cancer (CRC) and specificity of the mt-sDNA 2.0 test.
NCT00900224
RATIONALE: Studying samples of tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at tissue and blood samples from patients with acute myeloid leukemia.
NCT00003861
This research trial studies molecular genetic features in blood and tissue samples from patients with newly diagnosed acute lymphoblastic leukemia or acute promyelocytic leukemia. Studying samples of blood and tissue from patients with acute lymphoblastic leukemia or acute promyelocytic leukemia in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
NCT03653702
In this research study the investigators want to study a safe, radiation-free technique known as contrast-enhanced ultrasound that may improve the ability to diagnose or evaluate renal scarring compared to regular ultrasound. This technique requires injection into a vein of a small amount of contrast material called Lumason. Contrast material is a type of dye that helps the investigators image the structures in the body more clearly. If this technique is successful, the need for DMSA studies may be avoided to diagnose or evaluate kidney scarring. DMSA is a more expensive test, causes radiation exposure, may require sedation and/or injection of contrast agents with the potential to cause allergic reactions.
NCT03919799
This randomized, placebo-controlled phase 2 study was seeking to evaluate the efficacy and safety of belumosudil (KD025) for the treatment of diffuse cutaneous systematic sclerosis. Enrolment was terminated earlier than planned for business reasons unrelated to safety. A total of 36 participants were enrolled and randomized into 3 groups to either receive orally administered belumosudil (200 milligrams \[mg\] once daily \[QD\] and 200 mg twice daily \[BID\]) or matched placebo in 1:1:1 ratio in the double-blind (DB) period of this study. Study drug dosing was for 52 weeks: double-blinded for the first 28 weeks followed by an open-label extension of 24 weeks. After unblinding, the participants on belumosudil continued on the same belumosudil dose whereas the participants in the placebo group were re-randomized to one of the belumosudil doses in a 1:1 ratio.
NCT00350272
Elvucitabine, a novel nucleoside analog, is being studied as a treatment for participants with human immunodeficiency virus (HIV)-1. This Phase 2 study will enroll 60 HIV-1-naive participants to assess the efficacy and safety of elvucitabine compared to lamivudine in combination with tenofovir and efavirenz as measured by changes in the participant's HIV-ribonucleic acid (RNA) level and CD4 cell count. The study treatment will be 12 weeks of blinded study medication followed by an additional 84 weeks of open-label treatment if the participant's response to treatment meets certain endpoints. The pharmacokinetics of elvucitabine will also be assessed during the study.
NCT00566826
Knee osteoarthritis is one of the most common causes of disability in older adults. Total knee replacement (TRK) surgery is often an effective solution when persistent pain does not sufficiently improve with non-surgical treatment. Although most TKR surgeries are a success, an estimated 15% to 30% of patients report no clinically significant improvement in function 12 months after a TKR. This study will evaluate the effectiveness of a patient support program in increasing physical function after a TKR surgery.
NCT01431326
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged \<21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
NCT02431897
This study randomizes postmenopausal women with symptomatic pelvic organ prolapse planning native tissue transvaginal surgical repair to 6-8 weeks of preoperative and 1-year continued postoperative vaginal estrogen cream compared to placebo cream. This clinical trial and basic science investigation are designed to understand the mechanisms by which local estrogen treatment affects connective tissues of the pelvic floor and determine whether its use before and after prolapse repair will (i) improve success rates of the surgical intervention and minimize prolapse recurrence and (ii) impact favorably upon symptoms of other pelvic floor disorders.
NCT04605094
