Childhood Allergy and the Neonatal Environment (CANOE)

The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.

Comparison of Two- Versus Three-antibiotic Therapy for Pulmonary Mycobacterium Avium Complex Disease (MAC2v3)

NTM therapy consists of a multi-drug macrolide based regimen for 18-24 months. Treated patients frequently experience debilitating side effects, and many patients delay the start of antibiotic treatment due to these risks. Common side effects include nausea, diarrhea, and fatigue, and rare but serious toxicities include ocular toxicity, hearing loss, and hematologic toxicity. To date, most of the evidence underlying the current treatment recommendations has come from observational studies in which either a macrolide has been combined with rifampin and ethambutol, or in some cases combined with ethambutol alone. The proposed study will answer whether a third drug is necessary or whether taking two drugs can increase tolerability without a substantial loss of efficacy.

Systems Biology of Early Atopy (SUNBEAM)

The goal of this study is to establish a birth cohort that collects prenatal and early life biosamples and environmental samples and rigorously phenotypes young children for food allergy and Atopic Dermatitis (AD) to identify prenatal and early life markers of high risk for food allergy and AD, as well as biological pathways (endotypes) that result in these conditions. Primary Objectives: - To study the role and interrelationships of established and novel clinical, environmental, biological, and genetic prenatal and early-life factors in the development of allergic diseases through age 3 years, with an emphasis on atopic dermatitis and food allergy - To apply systems biology to identify mechanisms and biomarkers underlying the development of food allergy, atopic dermatitis, and their endotypes - To collect, process, and assay or store environmental and biological samples for current and future use in the study of allergic disease development

• Provide written informed consent Donor selection priority: The original kidney donor will be the first choice of donor peripheral mononuclear cells. If the original donor is not available or does not meet all donor eligibility criteria, alternative related donors will be selected, with preference for fully matched related donors (6/6 HLA match, considering HLA-A, -B, and -DRB1 genes) over related donors with partial HLA match (≥ 2/6 HLA match, considering HLA-A, -B, and -DRB1 genes). Note that if the selected donor is related, but not a biological parent or child of the recipient (i.e., at least haploidentical), then high resolution testing of HLA-A and HLA-B will be performed on donor and recipient (if high resolution HLA genotyping not already available in the medical record). If the degree of matching at high resolution reveals a less favorable match than an alternative donor, then prioritization of the alternative donor will occur.

Allergic Disease Onset Prevention Study (adored)

This is a Phase 1b/2, randomized, double-blind, multi-center study to evaluate the safety, tolerability, and preliminary clinical efficacy of STMC-103H in neonates and infants at risk for developing allergic disease (Type 1 hypersensitivity). Subjects will be enrolled in a three-part sequential approach. Participants in the safety-run portion of the study (Part A1: 1 year to <6 years of age and A2: 1 month to <12 months of age) will receive 28 days of treatment with STMC-103H or placebo, followed by 28 days of follow-up. A Data and Safety Monitoring Committee (DSMC) will review safety data after all patients in each part complete 28 days of therapy prior to enrolling the next part. After A2, Part B will enroll 224 patients for 336 days of treatment with STMC-103H or placebo, followed by 336 days of follow-up. Stool, blood, and optional samples will be collected in Parts A2 and part B. Primary safety endpoints are frequency, type and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs), as well as findings on physical exams, vitals, and safety laboratories. The primary efficacy endpoint is incidence of physician-diagnosed atopic dermatitis at day 336.

Phase I Trial to Evaluate VLP Peanut in Healthy and Peanut Allergic Subjects (PROTECT)

This phase I clinical trial is designed to evaluate the safety and tolerability of VLP Peanut in healthy subjects and in subjects with peanut allergy (PA). This clinical trial will evaluate the immunotoxicity profile of VLP Peanut in healthy subjects and assess the immunotoxicity profile and the degree of reactogenicity (allergenicity) in subjects with PA. This clinical trial will also explore preliminary proof of efficacy of VLP Peanut in subjects with PA.

Efficacy and Safety of PQ Grass in Subjects With Seasonal Allergic Rhinitis and/or Rhinoconjunctivitis Induced by Grass Pollen

The PQGrass306 (G306) clinical trial is the pivotal Phase III efficacy clinical trial of PQ Grass. The aim of the G306 pivotal clinical trial is to confirm the efficacy and safety of the optimal effective dose of PQ Grass 27600 SU. This will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak grass pollen season (GPS).

A Multi-center, Single-arm Trial Exploring the Safety and Clinical Effectiveness of RBX2660 Administered by Colonoscopy to Adults With Recurrent Clostridioides Difficile Infection (CDI-SCOPE)

This trial will be initiated to explore whether RBX2660 (REBYOTA®) could be suitable for administration by the practice of colonoscopy. More specifically, the purpose of this trial is to explore the safety and clinical effectiveness of RBX2660 when delivered by colonoscopy to adults with rCDI. The experience of physicians will be documented through a physician-experience questionnaire to explore the usability of RBX2660 in clinical practice for colonoscopic administration. Furthermore, to explore the patient-experience of RBX2660 treatment, each trial participant will be offered to undergo a structured interview.

Microbes and Respiratory Illnesses (MARI)

This study is called the Microbes and Respiratory Illnesses (MARI) Study. Children growing up on farms are exposed to many types of microbes that could be beneficial. It is thought that increased exposure to certain types of microbes early in life helps to develop a healthy immune system and reduce the risk for severe common cold illnesses, breathing problems, and allergies.
