Filter by:B7451029 is a Phase 3 study to investigate PF-04965842 in adult patients who have moderate to severe atopic dermatitis and use background topical therapy. The efficacy of two dosage strengths of PF-04965842, 100 mg and 200 mg taken orally once daily will be evaluated relative to placebo over 12 weeks. The efficacy of the two dosage strengths of PF-04965842 will be compared with dupilumab in terms of pruritus relief at 2 weeks. The two dosage strengths of PF-04965842 and dupilumab 300 mg injected subcutaneously once every two weeks (with a loading dose of 600 mg injected on the first day) will also be evaluated relative to placebo over 16 weeks. The safety of the investigational products will be evaluated over the duration of the study. Subjects will use non-medicated emollient at least twice a day and medicated topical therapy such as corticosteroids, calcineurin inhibitors or PDE4 inhibitors, as per protocol guidance, to treat active lesions during the study. Subjects who are randomized to receive one of the two dosage strengths of PF-04965842 will also receive placebo injectable study drug every two weeks until Week 16 and then will continue on receiving only the oral study drug for 4 weeks. Subjects who are randomized to receive dupilumab injections every two weeks will also receive oral placebo to be taken once daily until Week 16 and will then continue to receive only the oral placebo for 4 weeks. Subjects who are randomized to the placebo arms, will receive both daily oral placebo and injectable placebo every two weeks until Week 16, after which they will receive either 100 mg or 200 mg of PF-04965842 taken orally once daily for 4 weeks, dependent upon which arm they have been allocated to. Eligible subjects will have an option to enter a long-term extension study after completing 20 weeks of treatment.
This is a single-center randomized crossover trial. The investigators will target completion of 15 adults (age 18-65 years) with Type 1 Diabetes who use an insulin pump. After completion of the Screening Visit, each subject will participate in a 28-day at home Data Collection Period while using their personal insulin pump, a personal glucometer, a study CGM, and a study activity tracker (i.e., Fitbit). This data collection period may be extended to obtain to gather more days of quality data, if needed per principal investigator judgement. Once the data has been collected and processed, subjects will participate in two 24-hour admissions (Experimental and Control Admission) in a semi-controlled environment (i.e., hotel), performed in the assigned random order. During both admissions, subjects will use the personal insulin pump and glucometer, and a study CGM. The exercise session will consist of three 15-minute bouts of moderate-intensity exercise (i.e., stationary bicycle). Subjects will be provided a controlled dinner; the SI-informed bolus calculator will be used in the Experimental Admission while standard therapy will be used in the Control Admission. Subjects will then be observed overnight and discharged in the following morning.
Increasing drug resistance presents a significant challenge to the efficacies of common empiric eradication regimens for Helicobacter pylori treatment in the mainland of China. Tailored therapy may be the best choice to achieve good efficacy, especially in patients with penicillin allergy. Few studies had evaluated the patients with penicillin allergy.This study is designed to evaluate the efficacy and safety of antibiotic sensitivity-based tailored therapy for Helicobacter pylori treatment in the patients with penicillin allergy.
This is a 2:1 randomized, double-blind, placebo-controlled, multi-center, phase III clinical study evaluating the efficacy and safety of ZL-2306 (niraparib) for maintenance treatment in patients with platinum-sensitive relapsed ovarian cancer, fallopian tube carcinoma or primary peritoneal cancer (collectively referred to as relapsed ovarian cancer).The evaluation will be divided into two stages: Stage I will be conducted in all patients, and if the predetermined statistically significant difference is not reached, the trial will continue to extend to Stage II during which evaluation will be performed in gBRCA mutation-positive ovarian cancer patients.
To compare the HRQOL of AR101 characterized oral desensitization immunotherapy (CODIT™) in combination with standard of care (peanut avoidance, education) versus standard of care alone in peanut-allergic subjects aged 4 to 17 years.
Currently it is estimated that at least 25 million people in the United States are labeled as penicillin allergic although less than 1.5 million of these are truly allergic. Although combined skin testing and oral challenge is an evidence-based de-labeling strategy the high burden of penicillin allergy labels means these services are available only through specialty allergy practices. There is therefore a need to provide evidence for alternative penicillin de-labeling strategies such as direct oral challenge. Previous studies have utilized quasi-experimental designs. Test dose challenges are currently recommended as a strategy for removal of low risk drug allergies, but the current experience is limited to single arm observational studies and evidence-based strategies for identifying low risk patients are lacking. The investigators objective is to demonstrate the benefit of providing risk stratification in removing penicillin allergy labels for low risk penicillin allergy patients in a single arm intervention pilot trial in the ICU setting, which will pave the way for a future stepped wedge randomized control trial (stepped wedge trial entered separately in clinical trials.gov as NCT03702270)

The objective of this study is to compare the ocular response to CAC (using food allergen sensitive patients) to the systemic response of a previously performed oral food allergen challenge in the same subjects. This study will investigate the potential utility of CAC as a predictive tool for identifying patient response to food allergen challenge and maximum tolerated dose.
This phase I trial studies the best dose and side effects of NY-ESO-1 T cell receptor (TCR) engineered T cells and how well they work with NY-ESO-1 TCR engineered hematopoietic stem cells (HSCs) after melphalan conditioning regimen in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent) or does not respond to treatment (refractory). The melphalan conditioning chemotherapy makes room in the patient's bone marrow for new blood cells and blood-forming cells (stem cells) to grow. Giving NY-ESO-1 TCR T cells and stem cells after the conditioning chemotherapy is intended to replace the immune system with new immune cells that have been redirected to attack and kill the cancer cells and thereby improve immune system function against cancer. Giving NY-ESO-1 TCR engineered T cells and HSCs after melphalan may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.
The objective of this study is to assess whether intake of baked and then chilled potatoes over a 24-h period, compared to intake of isocaloric, carbohydrate (CHO)-matched foods low in fiber and resistant starch (RS), will increase insulin sensitivity, breath hydrogen and satiety, and decrease hunger and free fatty acid (FFA) levels in overweight or obese men and women at risk for metabolic syndrome and diabetes mellitus.
