The main purpose of this study is to compare how long subjects with esophageal cancer live overall or live without disease progression after receiving nivolumab and ipilimumab or nivolumab combined with fluorouracil plus cisplatin versus fluorouracil plus cisplatin
The study consists of 4 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in participants with moderately to severely active Crohn's disease (CD) who responded to intravenous risankizumab induction treatment in Study M16-006 or Study M15-991; - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in participants who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in participants who completed Sub-study 1, Sub-study 2, another AbbVie risankizumab Crohn's disease study, or participants who responded to induction treatment in Study M16-006 or Study M15-991 with no final endoscopy due to the Covid-19 pandemic. Additional objectives are to further investigate long-term efficacy and tolerability of risankizumab; - Sub-study 4 (Open-label On Body Injector (OBI) administration and long-term extension study) to evaluate patient-reported outcomes, efficacy, safety, tolerability, and pharmacokinetics of risankizumab administered via OBI in participants who are receiving maintenance treatment with risankizumab. - OL CTE to ensure uninterrupted care in accordance with local regulations until risankizumab is commercially available for participants who completed Sub-study 3, Sub-study 4.
This study includes two periods. The main objective of Period 1 is to compare the efficacy of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo and versus adalimumab (Humira®) in participants with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response to non-biologic DMARDs (DMARD-IR). Period 1 is also designed to compare the efficacy of upadacitinib 15 mg and 30 mg QD versus placebo for the prevention of structural progression. The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg and 30 mg QD in participants who have completed Period 1.
The study objectives of Period 1 are to compare the efficacy, safety, and tolerability of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo for the treatment of signs and symptoms in adults with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response or intolerance to biologic disease-modifying anti-rheumatic drug (bDMARD). The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg QD and 30 mg QD in participants who have completed Period 1.
Apixaban for the treatment of venous thromboembolism in patients with cancer: a prospective randomized open blinded end-point (PROBE) study
"Healthy Bellies" is an intervention program with pregnant women, based on the promotion of healthy lifestyles. It aims to evaluate the impact of the program in the health of both pregnant and newborn. This trial is being conducted with pregnant women, divided into control and intervention group. Are performed 3 assessment periods: 1 - beginning of the program; 2 - postpartum; 3 - 1 month after delivery. The intervention group has a program of 3 weekly physical exercise classes and the control group has the basic information that is usually provided by health professionals. With this program, it is expected to contribute with evidence to the best practice in the field of interventions in pregnancy and improve health outcomes of both pregnant and newborn.
The purpose of this study is to evaluate the efficacy and safety of pembrolizumab (MK-3475) plus chemotherapy vs placebo plus chemotherapy as neoadjuvant therapy and pembrolizumab vs placebo as adjuvant therapy in participants who have triple negative breast cancer (TNBC). After a screening phase of approximately 28 days, each participant will receive neoadjuvant study treatment (Pembrolizumab + Chemotherapy OR Placebo + Chemotherapy) based on the randomization schedule for approximately 24 weeks (8 cycles). Each participant will then undergo definitive surgery 3-6 weeks after conclusion of the last cycle of the neoadjuvant study treatment. After definitive surgery, each participant will receive adjuvant study treatment (Pembrolizumab OR Placebo) for approximately 27 weeks (9 cycles). Following adjuvant study treatment, each participant will be monitored for safety, survival and disease recurrence. The primary study hypothesis is that pembrolizumab is superior to placebo, in combination with chemotherapy, as measured by the rate of Pathological Complete Response (pCR) and/or Event-free Survival (EFS), in participants with locally advanced TNBC.
The name of this trial is MissionAD2. This phase 3 study consists of a Core and Open Label Extension (OLE) Phase in participants with Early Alzheimer's Disease (EAD), and will be conducted to evaluate the efficacy and safety of E2609. The Core is a 24-month treatment, multicenter, double blind, placebo controlled parallel group study. The OLE is a 24-month treatment, one group study. The data for end points for the studies E2609-G000-301 (NCT02956486) and E2609-G000-302 (NCT03036280) will be pooled for a combined total of 1900 participants.
This is a phase II, open label, multi-center, intra-patient dose escalation study to characterize the pharmacokinetics (PK) after oral administration of eltrombopag in combination with immunosuppressive therapy in pediatric patients with previously untreated or relapsed/refractory severe aplastic anemia or recurrent aplastic anemia.
This study is designed to evaluate the long-term safety and efficacy of Upadacitinib in participants with ulcerative colitis (UC) who have not responded at the end of the induction period in Study M14-234 Substudy 1, who have had loss of response during the maintenance period of Study M14-234 Substudy 3, or who have successfully completed Study M14-234 Substudy 3.
