Treatment of POEMS Syndrome With Daratumumab
POEMS SyndromeThis trial investigates the use of Daratumumab (DARA), an antibody directed at the human cluster of differentiation 38 (CD38) molecule, for the treatment of patients with Polyneuropathy, Organomegaly, Endocrinopathy, m Protein Component, Skin Changes (POEMS) syndrome. This trial will enroll ten subjects, who will complete 12 four-week cycles of DARA, in combination with the immunomodulatory drug (IMiD) lenalidomide. Objectives of this study include improvement in neuropathy and performance status, as well as improvement in laboratory values and survival.
Ixazomib Citrate, Lenalidomide, and Dexamethasone in Treating Patients With POEMS Syndrome
PlasmacytomaPOEMS SyndromeThis phase II trial studies how well ixazomib citrate, lenalidomide, and dexamethasone work in treating patients with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Anti-inflammatory drugs, such as dexamethasone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Giving ixazomib citrate, lenalidomide, and dexamethasone may work better in treating patients with POEMS syndrome.
To Evaluate Efficacy of Red Dichromatic Imaging (RDI) in Achieving Hemostasis During POEM Using...
POEMS SyndromeHemostatic DisorderPeroral endoscopic myotomy (POEM) is a novel endoscopic technique for the treatment of achalasia and other esophageal motility disorders. Initially, it was introduced to the world by Inoue et al. in 2008.7 Thereafter; it was rapidly disseminated because of low invasiveness, higher efficacy and technical novelty. The steps of performing POEM include mucosal incision, submucosal tunnel creation, myotomy and closure of the incision. Mucosotomy (2.8%) is the most common adverse event in patients undergoing POEM.8 It can be due to excessive use of cautery because bleeding points could not be seen clearly with white light during active ooze. RDI will help in early recognition of the bleeding points, thus prompt hemostasis. Bleeding during POEM is not very uncommon(0.5-0.7%).9 Early recognition of bleeding points and quicker hemosasis help in decreasing complications. The utility of RDI in the peroral endoscopic myotomy is not studied so far to our knowledge. Hence in this study we would like to look into the utility of red dichromatic imaging in per-oral endoscopic myotomy.
A Cohort Study of Plasma Cell Disorders (PCDs) in PKUFH
Multiple MyelomaAmyloidosis10 moreThe 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.
Registry for Adults With Plasma Cell Disorders (PCD's)
Multiple MyelomaAmyloidosis7 moreThe 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).
POEMS Syndrome Treatment With Lenalidomide
POEMS SyndromePOEMS syndrome is a rare form of B cell dyscrasia combining a proliferation usually of plasma cells, a polyneuropathy, osteocondensing bone lesions and multiple other clinical signs. Lenalidomide appears to be particularly efficient in this pathology. The investigators propose a phase II multicentre protocol, based on the use of lenalidomide combined with dexamethasone in patients presenting a POEMS syndrome, either de novo or resistant or in relapse. Patients who can be treated by local radiation or intensive treatment with stem cell support will undergo 2 cycles of the lenalidomide-dexamethasone (Len-Dex) combination before radiation or intensive treatment (Group 1), the other patients will undergo 9 cycles of the Len-Dex combination (Group 2). A biological study is coupled with this clinical protocol in order to define the best biological markers predicting clinical responses, to better understand the POEMS pathophysiological mechanisms and to set up a bank of samples which can be used to study this rare pathology.

Polyneuropathy, Impairments and Physical Activity - The PolyImPAct Study
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)Vasculitic Neuropathy7 moreThe project aims to investigate the validity, and reliability of outcome measures of muscle strength, functioning (gait, balance, and fine motor skills), physical activity, and patient-reported outcome measures of functioning (gait, balance, and fine motor skills), and daily living among patients with polyneuropathy. Further, the project aims to compare physical activity and patient-reported outcome measures of functioning (gait, balance, and fine motor skills), and daily living among patients with polyneuropathy with physical activity and patient-reported outcome measures of functioning (gait, balance, and fine motor skills) and daily living in healthy adults.
