This research aims to evaluate the effects of litifilimab (BIIB059), a monoclonal antibody, in adults with active subacute or chronic cutaneous lupus erythematosus (CLE), with or without systemic lupus erythematosus (SLE). Participants have active skin symptoms of CLE that have not improved with antimalarial therapy or had difficulties continuing that treatment. The study focuses on reducing skin disease activity using several scores including CLA-IGA-R and CLASI, while also assessing safety, immune response, and quality of life. Participants will be randomly assigned to receive either litifilimab or a placebo injection under the skin every four weeks during a 24-week double-blind period where neither participants nor researchers know which treatment is given. After this, all participants will receive litifilimab injections every four weeks for an additional 28 weeks. Those who complete the treatment may join a long-term extension study or enter a follow-up safety period lasting up to 24 weeks. Total participation may last up to 80 weeks. Throughout the study, researchers will monitor skin disease activity using the CLA-IGA-R erythema score and the CLASI-A activity score to see how many participants improve. They will also assess safety, tolerability, immune system effects, and participants' quality of life using questionnaires. These evaluations occur regularly during both treatment periods and follow-up to understand the impact of litifilimab on CLE symptoms and overall health.

Researchers are evaluating a new treatment called ifinatamab deruxtecan (I-DXd) for men with metastatic castration-resistant prostate cancer (mCRPC). This study compares I-DXd to chemotherapy to see if it helps people live longer overall and live longer without their cancer worsening. It is a Phase 3, open-label trial focused on patients who have progressed on prior therapies and have evidence of metastatic disease. Participants receive either I-DXd through an intravenous infusion every 3 weeks or docetaxel chemotherapy administered every 3 weeks. Prednisone tablets are also given daily as part of the treatment plan. Before each I-DXd dose, premedication is provided to help prevent nausea and vomiting using a combination of drugs such as corticosteroids and anti-nausea medicines. Treatment continues until disease progression, unacceptable side effects, or other reasons to stop. During the study, researchers monitor overall survival and how long patients live without their cancer progressing, for up to about 36 months. Participants undergo tumor tissue collection, scans, and assessments to track disease status and side effects. Safety is closely watched throughout treatment. The study includes men aged 18 and older with confirmed prostate cancer and metastatic disease who have previously received certain hormone therapies but no prior taxane chemotherapy for mCRPC.

The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection as well as or better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it

Researchers are evaluating molnupiravir, a study medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 more effectively than a placebo. This Phase 3 randomized, placebo-controlled, double-blind study focuses on non-hospitalized adults at high risk of severe disease progression due to COVID-19. The study addresses the need for alternative treatments for people who cannot take certain COVID-19 medications due to availability or potential drug interactions. Participants will receive either molnupiravir or a placebo, both given orally as two 400 mg film-coated tablets every 12 hours for 5 days, totaling 10 doses. Some participants may also receive remdesivir as part of standard care if clinically appropriate and available. The study compares the effects of molnupiravir with placebo in preventing severe illness outcomes. Throughout the study, participants will be monitored for outcomes such as hospitalization, death, or medically attended visits related to COVID-19 up to 29 days. Safety is assessed by tracking adverse events for up to about 5 months and discontinuation of study treatment due to adverse events for about 5 days. The study involves laboratory tests, symptom assessments, and safety evaluations to understand molnupiravir's impact on disease progression and participant health.

Researchers are studying adults with confirmed Primary Biliary Cholangitis (PBC) and cirrhosis, a scarring of the liver caused by damage to bile ducts. PBC is a slowly progressing disease that causes bile acid buildup and further liver damage, which can lead to cirrhosis. This study aims to evaluate if elafibranor, a daily medication, can prevent worsening clinical outcomes such as the need for liver transplant or death, compared to a placebo. It also looks at the safety of long-term elafibranor use and its effect on symptoms like itching and tiredness. Participants will take either an 80 mg tablet of elafibranor or a matching placebo once daily for up to 3.5 years in a double-blind setup, meaning neither the participants nor researchers know who receives which treatment. This long-term treatment period is designed to monitor the drug's impact over time. The study includes two groups: one receiving elafibranor and the other receiving placebo, with treatment lasting up to approximately 42 months. During the study, participants will be regularly assessed from the start until 4 weeks after treatment ends, with a maximum involvement of 3.5 years. Researchers will measure event-free survival, tracking if participants avoid clinical events indicating disease worsening. Safety monitoring will include tracking side effects and overall health, while symptom impact will be evaluated. Participants will provide informed consent and follow the study protocol throughout this extended observation period.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

Researchers are studying the safety and tolerability of budoprutug, a humanized monoclonal antibody that targets CD19 cells, in adults with primary membranous nephropathy (PMN). This Phase 2, open-label, multicenter trial focuses on patients who are anti-PLA2R antibody positive and continue to have proteinuria despite optimized RAAS inhibition. The study aims to evaluate three different intravenous dose regimens of budoprutug and their effects on this specific kidney condition. Participants will receive budoprutug through single intravenous doses on Day 1, Day 15, Day 169, and Day 183 within one of three sequential dose groups. Approximately 45 subjects will be enrolled, each receiving treatment according to their assigned dosing schedule. The study includes a follow-up period through Week 48, with additional monitoring for B-cell recovery as needed. During the study, participants will undergo safety assessments including monitoring for treatment-emergent adverse events up to 48 weeks. Researchers will also evaluate pharmacodynamics and preliminary efficacy through laboratory tests and clinical evaluations. Regular visits will include tests for kidney function, protein levels in urine, and blood cell counts, alongside other health assessments to ensure participant safety and gather data on how the drug affects the disease.

Researchers are evaluating the safety and effectiveness of combining petosemtamab with pembrolizumab compared to pembrolizumab alone as a first treatment for people with recurrent or metastatic PD-L1 positive head and neck squamous cell carcinoma (HNSCC). This Phase 3, randomized, open-label study focuses on patients who have not received previous systemic therapy for incurable recurrent or metastatic disease, though prior therapy for locally advanced disease is allowed under certain conditions. The study excludes patients who have been treated with anti PD-(L)1 or anti-EGFR therapies except in specific cases. Participants will receive either the combination of petosemtamab plus pembrolizumab or pembrolizumab alone as their first-line treatment for this condition. The study includes detailed eligibility criteria based on tumor location, PD-L1 expression, health status, and prior treatments. Treatment effects will be observed over time with a focus on overall survival and tumor response rates measured according to standard criteria. During the study, participants will undergo assessments including tumor biopsies, imaging scans to measure disease progression, heart function tests, and evaluations of organ function. Safety and treatment response will be closely monitored up to approximately three years. The study also tracks overall survival and tumor response rate as primary outcomes, ensuring continuous follow-up and support throughout the trial period.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study to see if it can reduce the risk of major adverse cardiovascular events (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for a first ASCVD event. The study compares AZD0780 to a placebo and monitors participants from randomization until the primary analysis censoring date, followed by a final study closure visit. Participants will be randomly assigned to receive either oral AZD0780 or an oral placebo once daily. The treatment period lasts until the primary analysis censoring date, after which a study closure visit will occur. The study is event-driven and designed to assess the time to the first major cardiovascular event during treatment. During the study, participants will be closely monitored with various assessments to evaluate cardiovascular outcomes and safety over approximately 54 months. Researchers will track the time to first event of any component of MACE-PLUS and collect data to assess the effect of AZD0780 compared to placebo. The study includes regular visits and evaluations to ensure participant safety and adherence to treatment.

Researchers are evaluating the safety and effectiveness of HLX22 combined with trastuzumab and chemotherapy as the first treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 2, double-blind, randomized, and multiregional study compares this combination against trastuzumab and chemotherapy with or without pembrolizumab. The study aims to measure how well the treatments work in controlling the disease and improving survival for up to five years. Participants will be randomly assigned to one of two groups. One group receives HLX22 at 15 mg/kg every three weeks along with trastuzumab, chemotherapy (XELOX regimen), and possibly a placebo for pembrolizumab. The other group receives a placebo for HLX22 plus trastuzumab, chemotherapy (XELOX), and possibly pembrolizumab every three weeks. Treatment continues until the disease worsens, unacceptable side effects occur, withdrawal of consent, or other protocol-specified reasons. Throughout the study, participants will undergo regular assessments including tumor scans reviewed by an independent committee to evaluate progression-free survival and overall survival over up to five years. Other evaluations include safety monitoring and organ function tests. The study tracks how long patients live without disease progression and overall survival, aiming to better understand the benefits and risks of HLX22 combined with current standard treatments.
