Researchers are assessing the safety and effects of Ritlecitinib, a study medicine, for treating hidradenitis suppurativa (HS), a condition causing long-lasting, painful red skin lumps. This phase 2 study focuses on adults with moderate to severe HS who have not responded well to or cannot tolerate antibiotics. The goal is to compare experiences and outcomes between those receiving Ritlecitinib and those receiving a placebo. Participants will be randomly assigned to take either Ritlecitinib or a placebo pill once daily at home. The treatment involves an initial loading dose of Ritlecitinib for 8 weeks, followed by an 8-week maintenance dose, totaling 16 weeks of treatment. The placebo group will receive a matching pill with no active medicine. Over approximately 24 weeks, including screening and follow-up, participants will attend around 10 clinic visits for health evaluations, including physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. They will also track their medication intake and HS symptoms daily using an electronic diary on a mobile phone. The study will measure how many patients achieve at least a 50% improvement in HS symptoms by week 16 to evaluate treatment response and safety.

Researchers are evaluating the effectiveness of delgocitinib cream 20 mg/g applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis (PPP). This phase 2a, double-blind, two-arm trial focuses on adults diagnosed with PPP, a condition characterized by persistent pustules on the palms and/or soles, lasting more than three months. The study aims to assess skin improvement using the PPP Area and Severity Index (PPPASI) and other clinical evaluations over 16 weeks. Participants will be randomly assigned to apply either delgocitinib cream or the cream vehicle twice daily during a 16-week treatment period. The study involves approximately 9 visits over about 18 weeks in total. The trial is designed to compare the two treatments' effects on PPP severity, with a thorough monitoring process throughout the study period. During the trial, participants will undergo clinical assessments including photographic evaluations to confirm PPP diagnosis, PPPASI scoring to measure skin improvement, and physician global assessments. Safety and treatment adherence will be closely monitored. The main outcome measure is the number of participants achieving at least a 75% improvement in PPPASI score from baseline at week 16. The study also includes safety checks and follow-up to ensure participant well-being throughout the trial.

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.

Researchers are investigating the long-term safety and effectiveness of APG777, a treatment for moderate-to-severe atopic dermatitis (AD), in patients who have already completed an initial APG777 study. This phase 2, multicenter, double-blind study focuses on those who may benefit from extended treatment with APG777 to better understand its ongoing effects and safety over time. The study includes three main periods: a screening visit that occurs at the end of the previous study's maintenance period, an extended treatment period where participants receive APG777 subcutaneous injections every 12 or 24 weeks, and a post-treatment follow-up period. Participants will continue using their chosen non-medicated moisturizer from the previous study throughout this extension. During the study, participants' health and response to treatment will be closely monitored, including tracking any treatment-emergent adverse events for up to three years. Researchers will assess the long-term safety and efficacy of APG777 while ensuring participants remain compliant with study protocols. This ongoing observation aims to provide detailed information on how APG777 affects patients over extended use.

Researchers are evaluating the effects, safety, and response to the medicine zasocitinib in children and teenagers aged 4 to under 18 years who have moderate-to-severe plaque psoriasis. The study is designed in two parts, with Part A including both children and teenagers and Part B including only children. Initially, only teenagers meeting the study criteria can join, with children joining later after more data is collected from other studies. In Part A, participants are randomly assigned to receive either zasocitinib or a placebo for the first 16 weeks, after which all receive zasocitinib for the rest of the study. Participants in Part B receive zasocitinib throughout. The treatment period lasts up to 208 weeks, followed by a 4-week safety follow-up. Both drug and matching placebo are used, and the study is conducted at multiple centers. Participants will attend multiple visits to the study site over a total duration of up to 4 years and 2 months, including a screening period of up to 35 days. Researchers will assess improvements in psoriasis severity using measures like the Static Physician's Global Assessment and Psoriasis Area and Severity Index at week 16. In Part B, they will also study how the body absorbs and processes zasocitinib by measuring drug levels at specific times. Safety and tolerability will be monitored throughout the study.

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 evaluating the safety and effectiveness of combining ruxolitinib, steroids, and lenalidomide in patients with relapsed or refractory multiple myeloma (MM) who show disease progression. Multiple myeloma is a cancer of plasma cells in the bone marrow, and despite advances in treatment, it remains incurable. This phase 1, open-label, multicenter study aims to explore new therapeutic options by targeting the JAK/STAT pathway involved in MM cell growth and survival. Participants will receive oral ruxolitinib daily on days 1 through 28, lenalidomide on days 1 through 21, and methylprednisolone daily on days 1 through 28 of each treatment cycle. The combination therapy is being studied to determine the maximum tolerated dose of ruxolitinib when used with steroids and lenalidomide. The study also monitors treatment-emergent adverse events over a period of up to 54 months. Throughout the study, participants will undergo various assessments including laboratory tests to monitor blood counts, liver and kidney function, and disease markers. Researchers will evaluate safety, tolerability, and efficacy by tracking adverse events and disease progression. Participants must be able to follow the study schedule and provide informed consent. The study also involves registration in the REVLIMID REMS program for safety monitoring related to lenalidomide use.

The study focuses on participants with advanced solid tumors and aims to investigate the safety, tolerability, early antitumor effects, as well as how the drugs are processed and act in the body. Participants will receive XL309 orally, either by itself or combined with olaparib, following assigned dosing schedules. The study includes a dose escalation stage to determine safe dosing and a cohort expansion stage to further explore effects in specific cancer types. Treatment effects and drug levels will be monitored over approximately 24 months. During the study, participants will undergo assessments including monitoring for treatment-related side effects, laboratory tests, and measurements of tumor responses. Researchers will track drug exposure and side effects that may require dose changes or discontinuation. The study will collect data on safety events, drug concentration in blood, and tumor response rates to understand the treatment impact over time.

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.
