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 studying a medicine called enlicitide to reduce low-density lipoprotein cholesterol (LDL-C) in adults with high cholesterol (hyperlipidemia). This trial aims to find out if taking enlicitide together with rosuvastatin, a standard cholesterol-lowering drug, works better than a placebo in lowering LDL-C levels. The study is a Phase 3 trial that is randomized, double-blind, and placebo-controlled to ensure accurate and unbiased results. Participants will receive oral tablets of enlicitide or placebo along with oral capsules of rosuvastatin or placebo. The study compares the effect of enlicitide plus rosuvastatin against placebo to evaluate their impact on LDL-C. The treatment period lasts 8 weeks, during which participants take their assigned medications as directed. During the study, researchers will measure the average percent change in LDL-C from the start of the trial to week 8. Participants will be monitored for safety and any side effects throughout the study. The total participation time includes screening, treatment, and follow-up assessments to evaluate the medicines' effects and safety in adults aged 18 to 64 with hyperlipidemia.

Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. 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 investigating new treatments for people with high-risk, early-stage breast cancer, specifically targeting triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/HER2-negative breast cancer. These types have little or no HER2 protein and involve hormones like estrogen or progesterone. The study aims to evaluate if the addition of sacituzumab tirumotecan (sac-TMT), a targeted therapy, combined with pembrolizumab and chemotherapy can improve outcomes compared to pembrolizumab with chemotherapy alone. Participants receive treatments including sacituzumab tirumotecan, pembrolizumab, and chemotherapy drugs such as carboplatin and paclitaxel, all given by intravenous infusion. Rescue medications like antihistamines, acetaminophen, dexamethasone, or steroid mouthwash may be used as needed. The study is randomized and open-label, comparing sac-TMT followed by chemotherapy plus pembrolizumab to chemotherapy and pembrolizumab without sac-TMT. During the study, researchers will monitor participants up to about 30 weeks to assess the percentage of people with no remaining cancer cells at surgery. They will also follow participants for up to approximately 92 months to track event-free survival, meaning time without cancer growth, spread, or return. Participants will undergo imaging, clinical assessments, and laboratory tests to evaluate treatment effects and safety throughout the study.

Researchers are evaluating tulisokibart as a potential treatment for radiographic axial spondyloarthritis (r-axSpA), a type of arthritis causing pain, stiffness, and inflammation in the spine and pelvis joints, visible on X-rays. This Phase 2b study aims to determine if different doses of tulisokibart improve symptoms better than a placebo, which looks like the study medicine but contains no active drug. The study has two main parts: a 16-week placebo-controlled period where participants receive either tulisokibart or placebo through subcutaneous injections, followed by a 124-week long-term extension divided into a 40-week main extension and an 84-week optional extension. This allows researchers to assess both the short-term and longer-term effects and safety of tulisokibart. Participants will be monitored for their response using the Assessment of Spondyloarthritis International Society (ASAS) 40 response at week 16 as the primary outcome. Throughout the study, researchers will evaluate disease activity and safety while tracking symptoms and any side effects. The total involvement spans up to 140 weeks, including both initial treatment and extension phases.

Researchers are conducting a Phase 3 clinical trial to study the effects of relutrigine in people with developmental and epileptic encephalopathies (DEEs). The study is designed to evaluate the drug's efficacy, safety, tolerability, and how the body processes it compared to a placebo. This trial includes participants aged 2 to 65 years who have experienced seizure onset before age 12 and have a confirmed diagnosis of DEE. Participants will be randomly assigned to receive one of two doses of relutrigine (1.0 mg/kg/day or 1.5 mg/kg/day) or a placebo. The medication is given once daily either by mouth or through a gastrostomy or jejunostomy tube. After the initial double-blind treatment period, there is an open-label extension where all participants may receive the study drug. During the study, participants will be monitored for changes in seizure frequency over 16 weeks as the primary outcome. Safety and tolerability will also be assessed throughout the trial. Various evaluations, including heart monitoring and seizure tracking, will be conducted to ensure participant well-being. The overall study will track participants from screening through treatment and follow-up phases to gather comprehensive data about relutrigine's effects.

Researchers are evaluating the safety, tolerability, and therapeutic effects of a combination treatment using BNT113 and pembrolizumab compared to pembrolizumab alone for patients with unresectable recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that is positive for human papillomavirus 16 (HPV16+) and expresses the PD-L1 protein with a combined positive score of 1 or higher. This Phase II/III trial includes patients whose cancer cannot be treated with local therapies and who have not received prior systemic anticancer therapy for their current disease condition. The trial consists of two parts. Part A is a non-randomized Safety Run-In Phase to confirm the safety and tolerability of BNT113 combined with pembrolizumab at the selected dose. Part B is a randomized phase that compares BNT113 plus pembrolizumab against pembrolizumab alone as first-line treatment. Patients in Part A continue their treatment without randomization. Treatments are given by intravenous injection or infusion, and patients may receive either combination therapy or monotherapy for up to 24 months. There is also an optional pre-screening phase to test tumor samples for HPV16 DNA and PD-L1 expression before entering the main trial. Participants undergo regular assessments including tumor measurements based on RECIST 1.1 criteria confirmed by independent review. Researchers monitor treatment-emergent adverse events for up to 27 months in Part A and evaluate overall survival and progression-free survival for up to 48 months in Part B. Tumor tissue samples are collected before treatment to confirm eligibility. The study involves ongoing safety monitoring and efficacy evaluations throughout the treatment and follow-up periods.

Researchers are evaluating a phase II, randomized, double-blind, placebo-controlled study involving 48 adults aged 18 to 70 years who have recently been diagnosed with acute HIV infection. The study aims to assess whether adding a combination of HIV-specific broadly neutralizing antibodies (bNAbs) to standard antiretroviral therapy (ART) is safe and whether this combination can delay the return of detectable HIV viral levels, reduce viral reservoirs, and improve HIV-specific immune responses compared to ART with placebo. Participants receive either the combination bNAbs or placebo along with ART at the start of the study. The bNAbs include VRC07-523LS given as a 10 mg/kg intravenous infusion over 15 to 30 minutes and PGT121.414.LS given as a 5 mg/kg intravenous infusion over 30 to 60 minutes, both administered once at entry. ART consists of daily oral tablets containing bictegravir, emtricitabine, and tenofovir alafenamide. The study includes multiple steps: initial treatment with ART and antibody or placebo infusions (Step 1), analytic treatment interruption (ATI) to monitor viral rebound (Step 2 and Step 3), and ART restart when criteria are met (Step 4). Throughout the study, participants undergo regular visits with laboratory tests to monitor HIV viral load, CD4+ T-cell counts, safety labs, and pregnancy tests when applicable. Researchers track the occurrence of significant adverse events related to the study antibodies and measure the time it takes for HIV viral levels to rebound after stopping ART. Participants must adhere to contraceptive requirements and use barrier methods to prevent HIV transmission during ATI. The total study duration includes treatment, interruption, and follow-up phases lasting up to 24 weeks or longer depending on individual progress.

The trial investigates the use of volrustomig in participants with unresected locally advanced head and neck squamous cell carcinoma (LA-HNSCC) who have not shown disease progression after receiving definitive concurrent chemoradiotherapy (cCRT). The study aims to evaluate the efficacy and safety of volrustomig compared to observation in this patient population. Participants have tumors that express PD-L1 and the study is conducted as a Phase III, randomized, open-label, multi-center global trial. Participants are assigned to receive either volrustomig as sequential therapy following cCRT or to an observation group. The treatment period involves monitoring participants who have completed definitive cCRT but remain unresected and have no evidence of metastatic disease. The study focuses on participants with Stage III, IVA, or IVB LA-HNSCC according to AJCC criteria, who have not undergone tumor resection before cCRT and have not been treated with radiotherapy alone. During the study, participants are regularly evaluated for progression-free survival, with follow-up lasting up to approximately 8 years to assess long-term outcomes. Researchers will monitor safety and disease progression closely. The overall participation duration includes screening, treatment or observation, and extended follow-up to capture both efficacy and safety data over time.

Researchers are evaluating the safety and effectiveness of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) whose disease has not worsened after definitive platinum-based concurrent chemoradiation therapy. This Phase III, randomized, double-blind, placebo-controlled, international study involves multiple centers. Participants receive intravenous infusions of durvalumab and domvanalimab or durvalumab and placebo. The treatments are given after patients have completed concurrent platinum-based chemotherapy and radiation therapy with a total radiation dose of approximately 60 Gy. The study monitors patients over time to assess treatment effects and safety. During the study, participants undergo evaluations including tumor tissue analysis for PD-L1 status, performance status assessments, and monitoring of organ and marrow function. The main outcome measured is progression-free survival up to 8 years after randomization. Researchers also monitor for any adverse effects and disease progression throughout the study period.
