Researchers are evaluating remibrutinib (LOU064) in adolescents aged 12 to under 18 years who have chronic spontaneous urticaria (CSU) that is not well controlled by H1-antihistamines. This Phase 3 trial aims to assess the effectiveness, how the drug is processed in the body, and safety of remibrutinib compared to a placebo. The study also intends to gather long-term data on how well remibrutinib works and its safety over several years after treatment ends. The trial includes three periods. First, the core period is a 24-week double-blind phase where about two-thirds of participants receive remibrutinib and one-third receive placebo, with about 10 site visits over approximately 32 weeks. Next is an optional open-label extension lasting from one to three years, where participants who completed the core period may receive remibrutinib or enter an observational treatment-free phase depending on their symptoms. Participants may cycle through treatment and observational periods up to six times. Finally, an optional long-term treatment-free follow-up can last up to three years with one site visit and up to four phone calls. During the study, participants undergo assessments including changes in urticaria activity scores (UAS7), itching severity (ISS7), and hive severity (HSS7) measured from baseline to 12 weeks. Regular visits monitor safety, symptoms, and drug effects. The study tracks these measures to understand remibrutinib's impact on CSU symptoms and overall safety profile during and after treatment, with total participation potentially lasting several years.

Researchers are studying Helicobacter pylori infection, the main cause of gastric cancer, in adolescents aged 14-18 years in three regions of Chile. The trial aims to evaluate a "screen and treat" approach to eradicate H. pylori infection in asymptomatic teenagers, assessing its effectiveness and impact on clinical outcomes, serum biomarkers of gastric damage, and the gut microbiome. This research builds on previous findings showing high infection rates acquired early in childhood, with low spontaneous eradication and potential long-term gastric damage if untreated. The study involves screening up to 1000 adolescents with the Urea Breath Test (UBT) to identify persistent H. pylori infection confirmed by at least two positive tests over three months. Persistently infected participants will be randomized in a 2:1 ratio to receive either a 14-day antimicrobial treatment regimen (7 days of lansoprazole and amoxicillin followed by 7 days of lansoprazole, clarithromycin, and metronidazole) or no treatment. A subset of 60 non-infected adolescents will be observed as controls. Participants who remain untreated after six months will be offered eradication therapy. During the trial, adolescents will undergo multiple evaluations including UBT at baseline, one month post-treatment, and every six months thereafter, along with gastroenterological exams, blood samples for gastric damage biomarkers, and stool samples to assess gut microbiota and antimicrobial resistance. The primary outcomes include changes in infection status, gastric disease indicators, and biomarker levels up to six months post-treatment. The study also monitors antimicrobial resistance and gut microbiome changes over 2-3 years, with safety and reinfection rates tracked throughout follow-up.

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 the safety and effectiveness of rilzabrutinib compared to placebo in adults with active Immunoglobulin G4 Related Disease (IgG4-RD). This Phase 3, randomized, double-blind study aims to measure the time until the first IgG4-RD clinical disease flare during a 52-week treatment period. Additional goals include assessing disease control, flare-free rates, use of glucocorticoid rescue, and monitoring safety through adverse events, laboratory tests, and electrocardiograms. Participants will be randomly assigned to receive either oral rilzabrutinib tablets or placebo for 52 weeks. Glucocorticoids may be used as rescue medication if needed. The study includes a screening period lasting 4 to 6 weeks before treatment begins, followed by the 52-week double-blind treatment phase, and a 2-week follow-up after treatment. An optional open-label extension lasting up to 108 weeks is also available for participants. During the study, participants will attend 16 visits for assessments, which may include clinical evaluations, imaging tests such as CT, MRI, PET, or ultrasound to monitor disease activity, and laboratory tests. Researchers will track time to disease flare and collect data on flare-free rates, safety parameters, and medication use. Participants' vaccination status and contraceptive use will be monitored according to local guidelines, and overall study participation could last up to 60 weeks or longer if joining the extension phase.

Researchers are studying whether combining calderasib, a targeted therapy for the KRAS G12C mutation, with subcutaneous pembrolizumab can treat non-small cell lung cancer (NSCLC). The study aims to determine if people receiving calderasib with pembrolizumab live longer without their cancer growing or spreading compared to those receiving pembrolizumab with chemotherapy. This is a phase 3, randomized, open-label, multicenter clinical trial focusing on participants with advanced or metastatic nonsquamous NSCLC carrying the KRAS G12C mutation. Participants will receive one of two treatment combinations. One group will take calderasib orally along with subcutaneous pembrolizumab and berahyaluronidase alfa injections. The other group will receive subcutaneous pembrolizumab combined with chemotherapy drugs pemetrexed and a platinum-based drug, either carboplatin or cisplatin, administered by intravenous infusion. These treatments are given as first-line therapy, and the study evaluates their safety and effectiveness. During the study, researchers will monitor participants for progression-free survival, especially focusing on those with at least 1% PD-L1 tumor proportion score, for up to approximately 48 months. Participants will undergo regular assessments to track cancer progression and response to treatment. Safety and efficacy data will be collected throughout the study to understand how well the treatments work and their side effects over time.

Researchers are studying whether calderasib alone or combined with cetuximab can treat advanced solid tumors in people who have the KRAS G12C mutation. This phase 2, open-label trial aims to find out how many participants respond to these treatments and to compare their safety and tolerability. Participants receive calderasib by mouth and cetuximab through intravenous infusion. The study includes people with locally advanced or metastatic solid tumors other than colorectal cancer, who have already undergone standard treatments. The trial monitors response and side effects over time as participants receive either calderasib alone or in combination with cetuximab. During the study, participants undergo regular assessments to measure tumor response and track any side effects or adverse events. Researchers record how many people experience treatment-related side effects and how many stop treatment due to these effects. The study follows participants for up to approximately 76 months to assess long-term outcomes and safety.

Researchers are evaluating new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are investigating new treatments for extensive-stage small cell lung cancer (ES-SCLC), a type of lung cancer that has spread within or beyond the lungs. This trial evaluates the safety and effectiveness of combining two study medicines, gocatamig and ifinatamab deruxtecan (I-DXd), with or without standard chemotherapy and immunotherapy. Gocatamig is a T-cell engager therapy that helps the immune system target cancer cells, while I-DXd is an antibody drug conjugate designed to deliver cancer-killing agents directly to tumor cells. Participants will receive different treatment combinations based on the study part and arm to which they are assigned. Treatments include intravenous administration of gocatamig, I-DXd, atezolizumab, carboplatin, and etoposide. Rescue medications may be given as needed to manage side effects such as cytokine release syndrome or infusion reactions. Participants may be assigned to various treatment groups either per investigator choice or randomized, with some receiving maintenance treatments after initial induction therapy. Throughout the study, participants will be monitored for safety, including the occurrence of adverse events and dose-limiting toxicities, for up to about 58 months. Researchers will also assess tumor response by measuring cancer size changes. Other evaluations include biopsies, imaging scans, and clinical assessments to determine how well participants tolerate the treatments and how their cancer responds. The total duration of participation and follow-up will vary depending on the study phase and treatment arm.

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.

Researchers are evaluating the safety and effectiveness of ifinatamab deruxtecan (I-DXd) alone or combined with other treatments in people with metastatic castration-resistant prostate cancer (mCRPC). This study aims to understand how well patients tolerate the treatment, find a safe dose for combining I-DXd with other drugs, and measure prostate-specific antigen (PSA) levels during treatment. The study is part of a larger master screening protocol and includes patients with confirmed prostate adenocarcinoma who have progressive disease despite prior therapies. Participants receive treatments including I-DXd given through intravenous infusion, sometimes combined with other drugs such as docetaxel (IV), MK-5684, abiraterone, or enzalutamide (all oral). Before each I-DXd dose, patients take premedication to prevent nausea and vomiting. The study includes both a safety lead-in phase and an efficacy phase, with ongoing monitoring for side effects and tolerability. The combination therapies are carefully dosed and scheduled according to the study protocol. During the study, participants undergo regular assessments to monitor side effects, measure PSA response, and track any dose-limiting toxicities. Safety is closely followed, particularly during the first 21 days for combination treatments, and throughout up to 54 months for long-term outcomes. Researchers also observe if participants discontinue treatment due to adverse events. The study requires ongoing visits and evaluations to ensure participant health and collect data on treatment effects over time.
