NCT ID: NCT04489420 Terminated - Clinical trials for Glioblastoma Multiforme

Natural Killer Cell (CYNK-001) IV Infusion or IT Administration in Adults With Recurrent GBM

CYNK001GBM01
Start date: October 1, 2020
Phase: Phase 1
Study type: Interventional

This study will find the maximum safe dose (MSD) or maximum tolerated dose (MTD) of CYNK-001 which are NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy for the systemic cohort (IV) (intravenous). The intratumoral cohort (IT) will not be giving lymphodepletion. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating recurrent glioblastoma multiforme.

NCT ID: NCT04365101 Active, not recruiting - Pneumonia Clinical Trials

Natural Killer Cell (CYNK-001) Infusions in Adults With COVID-19

CYNKCOVID
Start date: May 13, 2020
Phase: Phase 1/Phase 2
Study type: Interventional

This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.

NCT ID: NCT04310592 Recruiting - Leukemia Clinical Trials

Natural Killer Cell (CYNK-001) Infusions in Adults With AML

CYNK001AML01
Start date: March 12, 2020
Phase: Phase 1
Study type: Interventional

This study will find the maximum tolerated dose or the maximum planned dose of CYNK-001 which contains natural killer (NK) cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating acute myeloid leukemia.

NCT ID: NCT02242968 Recruiting - Clinical trials for Physiological Effects of Drugs

Screening of Volunteers for Clinical Trials of Investigational or Licensed Vaccines or Antiviral Products

Start date: April 24, 2023
Phase:
Study type: Observational

Background: - Vaccines and antiviral therapies help prevent and treat diseases. Researchers need a group of healthy volunteers for clinical trials. Clinical trials are studies that test these vaccines and therapies in people. Objective: - To screen volunteers for clinical trials for investigational or licensed vaccines or drugs to treat or prevent virus infections. Eligibility: - Healthy adults age 18 or older. Design: - Participants will be asked questions about their health history, including sexual activity and drug use. They will give blood samples. They may have a physical exam. They may give a urine sample. - Participants may have the inside of their nose either swabbed or washed with some fluid. The fluid will be collected. They may give a stool sample. - Participants may have an electrocardiogram. Soft, sticky patches will be attached to participants chest, arms, and legs. They will lie still on a table while the patches detect the heart s electrical signals. A machine will record these signals. - Participants may have lung function tests. These tests measure the volume of air moving in and out of the lungs. Participants will forcibly blow air into a machine. - Participants will be told if any tests show a medical problem. - If a participant is eligible and decides to join an investigational clinical trial, researchers will explain the study and the risks involved. Participants will sign a separate consent for that clinical trial.

NCT ID: NCT01195181 Completed - Clinical trials for Chronic Liver Disease

Different PEG-interferon and Ribavirin Schedules for Chronic Hepatitis C in the Real Clinical Practice.

Start date: September 2005
Phase: Phase 4
Study type: Interventional

Hepatitis C virus (HCV) infection provokes thousands of deaths every year all over the world, being the major cause of progressive liver disease, primary hepatic cancer and liver transplantation. Today, a "curative" therapy is available, that can eradicate the viral infection and determine the regression of liver fibrosis, also in cirrhotic subjects. The current standard-of-care for HCV chronic infection is combination therapy with peginterferon (P-IFN) and ribavirin (RBV). However, this treatment is not only expensive but determines several side effects, that can reduce drug tolerance and hence, patient adherence to therapy. There are two types of available P-IFN on the market: P-IFN alfa-2a (Pegasys®, F.Hoffmann-La Roche) administered at a flat-dose of 180 mcg/week and P-IFN alfa-2b (PegIntron®, Schering-Plough) given at a weight-based dose of 50 to 150 mcg/week. Since only a single amino acid differentiates these types of IFN, administration strategies depend on their pegilation with molecules of 40 or 12kDa, respectively, that accounts for differences in the pharmacokinetic and pharmacodynamic drug-profile and influences probably also bioactivity. No comparative data are available on the benefits and costs of the licensed Peg-IFN plus RBV for the treatment of HCV infection in the real clinical practice, even if, the benefit and favourable cost-efficacy of this antiviral therapy is well established and of large consensus. Recently, the first randomized controlled mega-trial to compare antiviral therapeutic efficacy in naïve patients with HCV-genotype 1 infection during different regimens of P-IFN alfa-2b (at low and standard-dose) and P-IFN alfa-2a plus RBV, has been published, confirming a similar efficacy, of around 40%, obtained with the three schedules evaluated. In Italy, a regional program on the Surveillance and Control of HCV Infection, set up by the Regional Health Councillorship, has led to the development of a clinical and epidemiological observatory, constituted by a network of liver tertiary centres (Hepatological Cooperative Network of Veneto, HepCoVe). This collaborative group is connected on-line by a common database that, since 2003, has prospectively collected data on a cohort of more than 3000 patients with chronic HCV infection and, among them, of 506 naïve subjects that consecutively underwent combination therapy with P-IFN alfa-2a or alfa-2b plus RBV. The aim of this study was to rationalize and improve the social regional health program on antiviral treatment of chronic hepatitis C by assessing the different schedules utilization of P-IFN plus RBV as well as the respective therapeutic effectiveness, safety and costs in the real clinical practice (Project A).
