Filter by:Non-tuberculous mycobacteria (NTM) are increasingly common and have a poor prognosis: 5-year mortality can reach 40 to 50%, depending on the type of mycobacteria and the immune system of the host involved. Cancer patients are at higher risk of infectious morbidity and mortality, which may be due to disease-related immune dysfunction, immunosuppressive effects of chemotherapy, or long-term placement of a vascular catheter. However, data on the treatment of NTM species that cause infections and the disease characteristics of these pathogens in cancer patients are limited despite the growing cancer population worldwide. Recently, M. avium infections have been described in patients suffering from cancers (hematological or not), in particular in patients receiving checkpoint inhibitors. Although the proportion of M. avium pneumonia in retrospective series is low (0.8-2%), it has been shown that this population is younger, suffers less from sub-pulmonary pathology. (indicating immunosuppression in these patients) but are therefore treated less than non-cancerous subjects. This retrospective study in CHU Amiens is searching on the number of side effects of NTM treatment in two groups (cancerous and no cancerous) to assess the cause of the decrease of NTM treatment in cancerous patients.
This is a phase 3 randomized, active-controlled, open-label, multicenter study that will be conducted in approximately 120 investigational sites worldwide. Subjects with either recurrent or refractory NMIBC (Ta high grade, T1 low or high grade, CIS) will be eligible for participation in this study. Refractory disease is defined as evidence of persistent high grade bladder cancer (Ta HG, T1, and/or CIS) at least 6 months from the start of a full induction course of BCG with or without maintenance/re-treatment at 3 months. Recurrent disease is defined as reappearance of disease after achieving a tumor-free status by 6 months following a full induction course of BCG with or without maintenance/re-treatment at 3 months. Subjects with recurrent disease must have recurred within 18 months following the last dose of BCG. Approximately 450 subjects will be randomized. The primary objective of this study is to evaluate the efficacy of intravesical EN3348 as compared with mitomycin C in the treatment of subjects with recurrent or refractory NMIBC. The secondary objective is to evaluate the safety of EN3348 as compared with mitomycin C in the treatment of subjects with BCG recurrent or refractory NMIBC. This study will consist of 4 phases: Screening, Induction, Maintenance and Follow-Up and will be conducted over 3 years.
