The purpose of this study is to evaluate the safety and the Clostridioides difficile infection (CDI) recurrence rate at Week 8 in participants who receive a 14-day course of VE303 or matching placebo. The objectives and endpoints are identical for Stage 1 (recurrent CDI) and Stage 2 (high-risk primary CDI).

Only adults will be enrolled at Mayo Clinic Arizona

The purpose of this study is to evaluate the safety and effectiveness of VE303 for participants with primary C. difficile infection (pCDI) at high risk for recurrence or subjects with recurrent C. difficile infections (rCDI).

This is a Multicenter, Double-Blind, Parallel-Arm, Placebo-Controlled, Phase 2 Study of the Efficacy, Safety, and Tolerability of Oral Full-Spectrum Microbiota® (CP101) in Subjects with Recurrence of Clostridium difficile Infection (PRISM3)

The purpose of this study is to obtain and report outcome data for adult subjects who received systemic antifungal therapy (AFT) for the treatment of invasive mucormycosis (IM) or invasive aspergillosis (IA) caused by a non-fumigatus species.

This study will assess the safety of a new biologic drug, RBX2660 (microbiota suspension) as a treatment for recurrent Clostridium difficile-associated diarrhea (CDAD), which is the primary symptom of recurrent Clostridium difficile infection. All eligible subjects will receive RBX2660.

This is the first prospective, multi-center, double-blinded, randomized controlled study of a microbiota suspension derived from intestinal microbes. Patients who have had at least two recurrences of C. difficile infection (CDI) after a primary episode and have completed at least two rounds of standard-of-care oral antibiotic therapy or have had at least two episodes of severe CDI resulting in hospitalization may be eligible for the study. Patients whose CDI returns in less than 8 weeks after the last assigned study treatment may be eligible to receive up to 2 treatments with RBX2660 in the open-label portion of the study.

The purpose of this study is to confirm the effectiveness of RBX2660 as compared to a placebo in preventing recurrent episodes of Clostridium difficile Infection (CDI) through 8 weeks.

This study will evaluate efficacy and safety information about RBX2660 for the treatment of recurrent Clostridium difficile infection (CDI). Enrolled subjects will receive one treatment with RBX2660 (microbiota suspension).

The purpose of this study is to evaluate clinical experience with donor screening for fecal transplant, and to evaluate the outcomes from fecal transplant and understand risk factors for fecal transplant failure and relapse after fecal transplant.

The purpose of this study is to identify known and unknown pathogens and antibodies that can cause severe disease in hospitalized patients.

The purpose of this study is to describe representative real-world patterns of care for the management of invasive fungal infections (IFIs), including invasive mold infection (IMI). Specifically, the study goals are to examine real world patient characteristics and treatment patterns, associated healthcare resource utilization, and outcomes associated with use of mold-active triazoles (MATs) to treat invasive fungal infections (IFIs).

The purpose of this open-label extension of CDI-001 (subsequently referred to as PRISM 3) is to evaluate the safety and efficacy in reducing recurrence of CDI in adults who had a recurrence within 8 weeks of receiving CP101 or placebo in PRISM 3. Subjects who are experiencing recurrent CDI will undergo screening procedures. Subjects who meet eligibility criteria will be eligible to be enrolled in the extension study and administered CP101. Approximately 70 subjects will receive CP101. The treatment duration will be 1 day. Subjects will be monitored for recurrence of CDI, safety, and tolerability for 24 weeks following receipt of CP101. The primary efficacy and safety endpoints will be evaluated at 8 weeks post treatment, and all subjects will continue to be followed for an additional 16 weeks for safety and recurrence of CDI.

This study will evaluate the efficacy of merimepodib (MMPD) administered orally every eight hours (q8h) for 10 days in adult patients with advanced COVID-19.
