NCT ID: NCT05283993 Recruiting - Multiple Myeloma Clinical Trials

A Cohort Study of Plasma Cell Disorders (PCDs) in PKUFH

Start date: July 1, 2021
Phase:
Study type: Observational

The primary aim is to establish a prospective cohort of patients with plasma cell disorders (PCDs). All of the hospitalized PCD patients who are willing to sign the informed consent form (ICF) will be included in this study. Clinical characteristics, treatment options and responses will be collected. Peripheral blood, bone marrow aspirate and urine samples before and after the treatment will banked for future research. Our team will focus on the clinical and pathological features of PCDs, the correlation between the minimal residual disease (MRD) status and prognosis, and the role of Tumor Microenvironment (TME) in the pathogenesis and progress of PCDs.

NCT ID: NCT03717844 Recruiting - Multiple Myeloma Clinical Trials

Registry for Adults With Plasma Cell Disorders (PCD's)

Start date: February 9, 2018
Phase:
Study type: Observational [Patient Registry]

The primary purpose of this protocol is to create a registry of patients with plasma cell disorders (PCDs), including for example the cancer multiple myeloma (MM), who complete the assessment, previously known as a "geriatric assessment," as is outlined in this protocol. Secondary objectives include measuring the response rate to participation of patients in this study, assessing patient satisfaction with the questionnaire, and gathering information that would lend support for future research into these types of assessments in patients with PCDs. Additionally the study offers an optional blood draw to look at a genetic marker of aging called p16INK4a (IRB 15-1899, IRB 15-0244).

NCT ID: NCT03042520 Recruiting - Diabetes Mellitus Clinical Trials

Long-term Outcomes of Chronic Hepatitis C Patients Post Sofosbuvir-based Treatment

LONGHEAD
Start date: August 2016
Phase:
Study type: Observational

Primary Objective: To evaluate the long-term outcomes including liver related morbidity, mortality and hepatocellular carcinoma (HCC) development as compared to those of historical control with interferon(IFN)-based treatment. Secondary Objective: 1. To access liver fibrosis progression/regression in CHC patients after sofosbuvir-based treatment. 2. To investigate the long-term outcomes of extrahepatic manifestations of the sofosbuvir-based treated cohort as compared to their pretreatment status.

NCT ID: NCT02856243 Recruiting - Hepatitis C Clinical Trials

Direct Antiviral Agents for Hepatitis C Virus-associated Cryoglobulinaemia Vasculitis

Start date: November 2013
Phase: N/A
Study type: Observational

Cryoglobulinemia are responsible for systemic vasculitis, and the most frequently targeted organs are the skin, joints, kidney and peripheral nervous system. Cryoglobulinemia vasculitides are associated with significant morbidity and mortality, and require therapeutic intervention. With the discovery of hepatitis C virus (HCV) as the etiologic agent for most cases of mixed cryoglobulinemia new opportunities and problems for crafting therapy of HCV mixed cryoglobulinemia (MC) have emerged. A new and major concern was the potential adverse effects that immunosuppressive therapy with glucocorticoids and cytotoxic drugs could have on an underlying chronic viral infection. Alternatively the discovery of HCV provided the opportunity to control HCV-MC with antiviral therapy based on the belief that the underlying infection was driving immune complex formation and resultant vasculitis. Inducing a sustained virologic and clinical response and minimizing the use of immunosuppressive drugs are the main goals in the treatment of patients with HCV-MC vasculitis. Aggressive antiviral therapy has been shown to induce a complete remission of HCV-MC in up to 70% of patients. New antiviral combination, Interferon (IFN)-free regimens have recently proved very high virological response rate and with a very good safety profile and now need to be evaluated in severe and/or refractory HCV-MC patient's population.
