Pilon Fracture With Intra-articular Injection of N-Acetylcysteine (Pilon NAC)
Pilon FractureHigh energy intra-articular fractures of the distal tibia, or Pilon fracture, is a devastating injury with multiple short and long term complications. The incidence of these injuries is increasing as survival rates after motor vehicle collisions increase. The current standard of care for high energy pilon fractures is to place an external fixator at the time of injury and then provide definitive internal fixation when the soft tissue envelope allows, which is usually around 10-14 days. Arguably, the most debilitating long term complication after a high energy pilon fracture is the development of post-traumatic osteoarthritis (PTOA), which occurs in 50% or more of pilon fractures within the first 2 years of surgery. The development of osteoarthritis occurs even in the presence of adequate restoration of the tibial plafond. Part of this issue lies in the fact that ankle joint cartilage is the thinnest of any major articular joint and sustains a great deal of damage at the time of injury. This impaction and injury initiates a cascade of events that ultimately result in cartilage cell death, or chondrolysis. Chondrolysis occurs via necrosis or apoptosis. Apoptosis occurs via a caspase pathway, while necrosis of chondrocytes likely occurs secondary to overproduction of reactive oxidant species (ROS). Recent animal models have demonstrated several things: chondrocyte death is highest along fracture lines, and likely undergo necrosis as opposed to apoptosis. The reason that PTOA likely occurs in such a high percentage of pilon fractures is because of this chondrolysis, and if a method can be developed to decrease the rate of chrondrocyte necrosis, then the rate of PTOA could potentially improve and improve patient outcomes overall. A recent bovine model examined the injection of N-acetylcysteine (NAC) after an intra-articular knee fracture and its effect on the cartilage cell viability. Their study demonstrated that chondrocyte cell viability after an injection of NAC within four hours of injury decreased chondrolysis from roughly 60% to about 30% at 48hrs. The effect was greater the closer to injury the injection occurred, and was statistically significant for 2 weeks. This indicates that free radical scavengers can potentially improve cartilage cell viability and help prevent the development of PTOA. No studies have been published on humans regarding injection of NAC after a fracture. However, a recent article examined the injection of NAC into osteoarthritic knees and found that it was effective in lowering certain cartilage degradation markers and was comparable to hyaluronic acid for both pain and function. NAC has been proven safe for both intra-articular injections and systemic injections in humans. Our study will focus on the improvement of cartilage cell viability with an injection of NAC. Our hypothesis is that the NAC intra-articular injection will increase the percentage of viable cartilage cell after sustaining a pilon fracture, when compared to a placebo injection of saline. The goal of this study is to examine the effects of an intra-articular injection of the amino acid NAC on cartilage cells after an intra-articular fracture of the ankle joint. The long-term clinical goal of this research is to reduce the incidence of post-traumatic osteoarthritis in the ankle joint after fracture.

Disease Modifying Therapies Withdrawal in Inactive Secondary Progressive Multiple Sclerosis Patients...
Multiple SclerosisFurther controlled and randomized prospective studies in Multiple sclerosis, analyzing the potential impact of treatment discontinuation on disability progression, focal disease activity and quality of life are needed. The optimum patient age and duration of inactive SPMS before treatment withdrawal and the monitoring procedures also need to be specified, the ultimate goal being to provide evidence-based recommendations for clinical practice. Following the previous retrospective experience, we decided to drive a multicenter prospective study in France based on the hypothesis that stopping disease modifying therapy will not induce an increased risk of disability progression and relapse in selected SPMS patients (older patients without lesion activity) but will improve the quality of life and may reduce treatment-related costs.

Comparison of ANCA and Anti-GBM Auto-antibodies Removal Kinetics Between Plasma Exchanges and Immunoadsorption...
Kidney FailureAcuteAnti-neutrophil cytoplasmic antibodies (ANCA), directed against myeloperoxidase (MPO) and against proteinase 3 (PR3), have a pathogenic role during ANCA (AAV) vasculitis. Glomerular basement membrane (MBG) antibodies also have a direct pathogenic role in Goodpasture's syndrome and anti-MBG antibody glomerulonephritis (GN). In some patients, the severity of renal and / or pulmonary involvement justifies the rapid purification of these autoantibodies by an apheresis procedure, while waiting for the effect of immunosuppressive treatments aimed at reducing their production. During vasculitis, plasma exchange (PE) is recommended in patients with severe renal impairment or intra-alveolar hemorrhage (2012 KDIGO Clinical Practice Guideline for Glomerulonephritis). Given certain disadvantages related to plasma exchanges (low volume of purified plasma, non-selective technique for immunoglobulins (Ig), need for replacement solute, induction of coagulation disorders), immunoadsorption (IA), already used in transplantation, has been developed in these indications. IA has indeed greater selectivity for Ig with a probable better purification capacity due to higher volumes of plasma treated per session. The price of IA is however higher than that of EP. These two apheresis techniques, EP and IA, are commonly used in France during severe forms of vasculitis ANCA or anti-MBG, without the superiority of one or the other has been demonstrated. As a result of higher plasma volumes being purified, AI may allow faster purification of pathogenic antibodies. No studies to date have specifically compared the purification kinetics of these antibodies between EP and IA. The CINEVAS study (VAScularite Antibody Purification CINetic) is a multicentric pilot study whose main objective is to compare the purification kinetics of ANCA (anti-MPO or anti-PR3) and / or anti- MBG in patients treated with EP versus those treated with IA

A Study of Belantamab Mafodotin Monotherapy in Multiple Myeloma Participants With Normal and Varying...
Multiple MyelomaBelantamab mafodotin is an antibody-drug conjugate (ADC) containing humanized anti- B-cell maturation antigen (BCMA) monoclonal antibody (mAb). Renal impairment is a major complication of multiple myeloma (MM) and the majority of MM participants is either at risk or already has renal dysfunction at initial diagnosis. The purpose of this study is to assess the pharmacokinetics (PK), safety, and tolerability of belantamab mafodotin monotherapy in participants with RRMM, who have had at least 3 lines of prior treatment (or at least 2 lines of prior treatment if ineligible for autologous stem cell transplantation ) and have either normal or impaired renal functions. The study will consist of two parts: part 1 will include participants with normal/mildly impaired renal function and severe renal impairment and part 2 will include participants with end-stage renal disease (ESRD), where participants are either not undergoing or require hemodialysis. Participants will be administered belantamab mafodotin at a dose of 2.5 milligram per kilogram (mg/kg) intravenously once in three weeks (Q3W) dosing in Part 1. Based on the Part 1 Safety/Pharmacokinetic (PK) data, Part 2 participants will be administered the dose of either 2.5 mg/kg or 1.9 mg/kg (or other adjusted dose). Participants will be treated with belantamab mafodotin monotherapy until confirmed disease progression, death, unacceptable toxicity, withdrawal of consent, or end of study, whichever occurs first. This study will include a screening phase, treatment phase, follow-up phase and a post analysis continued treatment (PACT) phase . The total duration of the study is approximately up to 48 months.
