NCT ID: NCT05135858 Not yet recruiting - Clinical trials for Primary Central Nervous System Lymphoma

Dose Dense Re-challenge of High Dose Methotrexate With Glucarpidase for Relapsed Primary Central Nervous System Lymphoma

METHOGLU
Start date: January 1, 2022
Phase: Phase 1
Study type: Interventional

High dose intravenous Methotrexate (HD-MTX) is the key drug in the treatment of primary central nervous system lymphoma (PCNSL). HD-MTX is usually delivered with time interval ranging from 10 to 21 days. Reduction of injection time interval is limited by MTX renal excretion and systemic toxicity. Glucarpidase (CPG2) is a recombinant bacterial rescue enzyme that cleaves circulating MTX into inactive metabolites, reducing plasma MTX concentrations within few minutes. The research hypothesis is that CPG2 used after HD-MTX injection allows to reduce time interval between MTX injections, increase dose intensity of the chemotherapy, reduce systemic toxicity and duration of hospitalization.

NCT ID: NCT05135663 Active, not recruiting - Clinical trials for Duchenne Muscular Dystrophy (DMD)

Extension Study of NS-089/NCNP-02 in DMD

Start date: June 23, 2021
Phase: Phase 2
Study type: Interventional

This is the extension study of NS-089/NCNP-02 (Study NCNP/DMT02), which is designed to assess the safety, tolerability and efficacy of NS-089/NCNP-02 in patients with Duchenne muscular dystrophy (DMD).

NCT ID: NCT05135650 Not yet recruiting - Clinical trials for Hematopoietic and Lymphoid Cell Neoplasm

Pharmacokinetics of Sotrovimab in Hematopoietic Stem Cell Transplant Recipients, COVIDMAB Study

Start date: May 1, 2022
Phase: Phase 1
Study type: Interventional

This phase I trial studies the process by which sotrovimab is absorbed, distributed, metabolized, and eliminated by the body (pharmacokinetics) in hematopoietic stem cell transplant recipients. Sotrovimab is a monoclonal antibody that may target and bind to a specific protein on SARS-CoV-2 and block its viral attachment and entry into human cells. This may slow the progression of the disease and accelerate recovery, and may potentially provide temporary protection against infection with SARS-CoV-2 in hematopoietic stem cell transplant recipients.

NCT ID: NCT05135585 Not yet recruiting - Clinical trials for SARS-CoV-2 Acute Respiratory Disease

Evaluation of the Post-vaccination Immune Response to COVID-19 in the New Caledonian Population

COVCAL
Start date: December 1, 2021
Phase: N/A
Study type: Interventional

The COVID-19 pandemic caused by SARS-CoV-2 since December 2019 has caused more than 210 million cases worldwide as of September 1, 2021. New Caledonia (NC) is an ultramarine French territory in the South Pacific so far relatively spared by this pandemic thanks to the establishment of a health lock. The vaccination campaign started locally on 20/01/2021 with the exclusive use of Pfizer's COMIRNATY mRNA vaccine. Vaccination is now offered to anyone over the age of 12. Vaccination against COVID-19 will be mandatory in New Caledonia as of October 31, 2021 for certain exposed populations and for the entire adult population as of December 31, 2021. Clinical trials of COVID-19 vaccines, including those of mRNA vaccines, have taken care to maintain ethnic diversity within their samples. Efficacy studies have not shown a significant difference in the efficacy of Pfizer COMIRNATY vaccine in white, black American, or Hispanic populations. The response of non-European non-Asian Oceanian populations to Pfizer COMIRNATY vaccination has not been specifically studied at this time. According to the 2019 census in New Caledonia, 41.2% of the population identified themselves as Kanak (Melanesian), 24% as European, 8.3% as Wallisian-Futunian (Polynesian), 11% as mestizo, and 8% as belonging to other communities including Tahitian (Polynesian), Indonesian, Ni-Vanuatu (Melanesian), and Vietnamese communities (8). Some recent data are in favor of a significant variability of susceptibility to pathogens in Oceanian populations, stemming from a genetic inheritance from Neanderthal man and his cousin Denisova man. In a context of vaccine hesitancy, it is therefore important to ensure that the immune response of the New Caledonian population (Melanesian, Polynesian, European or other communities) to vaccination against COVID-19 is similar to that of populations studied in large clinical trials.

NCT ID: NCT05135442 Not yet recruiting - Clinical trials for Thrombotic Thrombocytopenic Purpura, Acquired

Efficacy and Safety of Bortezomib as First-line Treatment of Acquired TTP

Start date: December 1, 2021
Phase: Phase 4
Study type: Interventional

To evaluate the efficacy and safety of bortezomib in the first-line treatment of patients with acquired TTP,we design this prospective, multi-center, single-arm interventional study.All enrolled TTP patients were given bortezomib 1.3 mg/m2 intravenous injection d1, 4, 8, on the basis of standard single membrane plasma exchange (2L/d) and hormone therapy (1mg/kg prednisone or equivalent methylprednisolone). 11 (4 doses in total). Bortezomib should be administered immediately after each plasma exchange, and the interval between the next plasma exchange is> 24h. Plasma exchange continued until the patient's platelet count was >100×109/L for 2 consecutive days, and then changed to once every other day for a total of two times and then stopped.

NCT ID: NCT05135364 Recruiting - Clinical trials for Unresectable Hepatocellular Carcinoma

HAIC Combined With Camrelizumab and TKI for Unresectable Hepatocellular Carcinoma After TACE Failure

Start date: November 5, 2021
Phase: Phase 2
Study type: Interventional

The efficacy and safety of HAIC combined with tyrosine kinase inhibitor and immunotherapy have been proved by the clinical research. In this single-arm, open-label, prospective study, for those patients with unresectable primary HCC, in the case of failure of TACE treatment, the combination of HAIC, TKI and immunotherapy is expected to bring new breakthroughs.

NCT ID: NCT05135065 Not yet recruiting - Clinical trials for Attention Deficit Hyperactivity Disorder

Community-Based Care for Minority Adolescents With ADHD: Improving Fidelity With Machine Learning-Assisted Supervision and Fidelity Feedback.

Start date: November 18, 2021
Phase: N/A
Study type: Interventional

This project proposes to reduce disparities in care among disadvantaged racial/ethnic minority adolescents with ADHD by improving community therapist fidelity to evidence-based behavior therapy through a technology-assisted supervision intervention. In Y01, the research team will work with stakeholders to develop the proposed supervision intervention utilizing two novel technologies: Lyssn + Care4 (LC4S). In Y02, a preliminary clinical trial (N=72) will be conducted in three community mental health agencies in Miami, FL. Adolescent participants will be randomly assigned to receive supervision from a therapist who is trained in LCS4 or provides enhanced supervision as usual(ESAU)using a permuted block randomization strategy that randomizes within site. There will also be double randomization of agency therapists to supervisors. Supervisors will deliver both conditions and investigators will test for contamination to determine the integrity of this design prior to a future R01 that measures patient outcomes. Data from therapists, adolescents and their parents, and supervisors will be collected pre-training, post-training, weekly during service delivery, at EBT completion, and at the end of the trial. The proximal intervention target is therapist fidelity to EBT and the distal targets are service delivery outcomes that include quality, quantity, and speed of delivery. Investigators will also measure indices of consumer fit: cost, acceptability, feasibility, and fidelity to supervision procedures. Sources of data will be audio recorded therapy and supervision sessions, therapist and supervisor report, and project and electronic health records. In longitudinal analyses, time will be modeled as a person-specific variable representing months since baseline. Investigators will nest adolescents within therapists for all analyses.

NCT ID: NCT05134597 Recruiting - Inflammation Clinical Trials

Gene Expression in Chronic Venous Leg Ulcers

GECVELUS
Start date: January 1, 2021
Phase:
Study type: Observational

Chronic Venous Disease (CVD) is a widespread clinical condition widely spread in the western countries that may negatively impact the quality of life (QoL) of affected patients. Chronic venous leg ulcers (CVLUs) are the most severe form of CVD, and several genetic and molecular alterations have been studied in order to understand the progression of CVD towards CLVUs. Chronic inflammation is a key element in CVLUs onset, and recently T helper 17 (Th-17) cells, a subtype of pro-inflammatory T helper (CD4+) cells defined by the production of a cytokine signature of which IL-17 represents the progenitor, seem to be related to several chronic disease. The aim of this study is to evaluate Th17- Gene Expression profile in patients with CVD and CVLUs.
