A 52-Week Study of Ritlecitinib Oral Capsules in Adults and Adolescents with Nonsegmental Vitiligo (Active and Stable) Tranquillo
The primary objective of this study is to compare the effect of treatment with olpasiran, to placebo, on the risk for coronary heart disease death (CHD death), myocardial infarction, or urgent coronary revascularization in participants with atherosclerotic cardiovascular disease (ASCVD) and elevated Lipoprotein(a).
This is a multi-center, randomized, quadruple-blind, placebo-controlled study to evaluate the efficacy and safety of batoclimab in adult participants with active CIDP. The study includes an up to 4-week Screening Period, an up to 12-week Washout Period, a 12-week Randomized Treatment Period (Period 1), an up to 24-week Randomized Withdrawal Period (Period 2), an up to 52-week Long-term Extension (LTE) Period (optional), and Safety Follow-up 4 weeks after the last dose of study treatment. The total study duration will be up to approximately 109 weeks. Eligible participants will be assigned to one of four cohorts based upon their baseline CIDP treatment (Cohorts A and D - immunoglobulin [Ig] or plasma exchange [PLEX]; Cohort B - corticosteroids; Cohort C - naive or untreated in previous 3-24 months) and whether they meet diagnosis according to the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) criteria (Cohorts A, B, and C) or clinical criteria only (Cohort D) at the time of screening.
The purpose of this study is to find out if PF-07081532 ("the active study drug"), is safe and helps treat people with obesity without diabetes to lose weight, and people with diabetes to keep their blood sugar in good control. Individuals diagnosed with diabetes that are on metformin or individuals with obesity without diabetes will be included in the study. Those participating in the diabetes part of the study, will receive either active study drug, placebo, or an approved treatment called Rybelsus. Those in the obesity part of the study, will receive either active study drug or placebo. The study will last for about 36 weeks except for the first 25% of the participants that enter in which case the study will last for approximately 48 weeks. during this time there will be visits every 4 weeks with phone calls in between.
B-cell Lymphoma is an aggressive and rare cancer of a type of immune cells (a white blood cell responsible for fighting infections). The purpose of this study is to assess the change in disease activity of epcoritamab when combined with intravenous and oral rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP) or R-CHOP in adult participants globally with diffuse large b-cell lymphoma (DLBCL). Change in disease activity will be assessed. Epcoritamab is an investigational drug being developed for the treatment of DLBCL. Study doctors put the participants in groups called treatment arms. Participants will receive epcoritamab combined with R-CHOP, followed by epcoritamab or R-CHOP followed by rituximab will be explored. Approximately 900 adult participants with with newly diagnosed DLBCL will be enrolled in the study in approximately 315 sites in globally. In the Arm 1, participants will receive subcutaneous epcoritamab combined with intravenous and oral R-CHOP followed by subcutaneous epcoritamab in 21-day cycles. In the Arm 2, participants will receive intravenous and oral R-CHOP followed by intravenous rituximab in 21-day cycles. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.
This is a 12-week (with an extension to 52 weeks in a subset of participants) study comparing the safety of BGF MDI HFO twice daily (BID) with BGF MDI HFA BID in participants with moderate to very severe COPD.
The purpose of this study is to demonstrate the slowing of the disease progression including the improvement of Chronic Obstructive Pulmonary Disease (COPD) symptoms in smoking subjects with mild to moderate COPD and a history of chronic bronchitis symptoms (sputum and cough) who switch to the Tobacco Heating System (THS) as compared to those who continue to smoke cigarettes.
This is a Phase 2b, randomized, double-blind, placebo-controlled study of EDP-938 administered orally for the treatment of non-hospitalized adult subjects with confirmed RSV infection who are at high risk for complications after RSV infection.
This study has 2 parts: First part is the main study and second part is the extension study. During the main study participants will receive 1 of 4 study medicines. If participants continue in the extension study, they will not receive any study medicine during the extension. The main study will look at how well CagriSema helps participants with excess body weight lose weight compared to a "dummy" medicine and 2 other medicines, cagrilintide and semaglutide. Participants will either get CagriSema, cagrilintide,semaglutide or "dummy" medicine. Which treatment participants get is decided by chance. They will take one injection once a week. The study medicine is injected briefly with a thin needle, typically in the stomach, thighs or upper arms. Extension study: After the main study, not all participants will continue in the extension study. The study staff will tell the participant if they will continue or not into the extension study. In the extension study we will look at what happens to the participant's body weight and diseases related to excess body weight after the participant stops taking the study medicine. The main study will last for about 1½ years and the extension study will last for another 2 years.
The purpose of this study is to evaluate the safety and efficacy of mRNA-1010 in preventing seasonal influenza in adults 50 years and older.
