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 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 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 evaluating KK2260 in patients with advanced or metastatic solid tumors in a Phase 1 clinical trial. The study aims to find the maximum tolerated dose (MTD) and assess the safety, tolerability, and effectiveness of KK2260 across multiple cancer types, including esophageal and head and neck cancers. The study includes initial dose escalation followed by evaluations of different dosing regimens tailored by cancer type. KK2260 is given through an intravenous infusion at various dose levels. The study is divided into parts: Part 1a focuses on finding the MTD while monitoring safety; Part 1b and Part 2 involve testing selected dosing regimens in specific cancers. Participants may undergo tumor biopsies before and after treatment to help assess the drug's effects. Participants will be closely monitored for safety and treatment effects for about one year. This includes regular blood tests every week to check many laboratory values such as blood cell counts, liver and kidney function, electrolytes, and immune markers. Vital signs, electrocardiograms, and performance status will also be tracked weekly. Researchers will record any side effects and dose-limiting toxicities. The thorough monitoring helps understand KK2260's impact over time and supports participant safety throughout the study.

Researchers are evaluating treatments for breast cancer that is hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-), specifically in cases where the cancer is either locally advanced and cannot be removed by surgery or has spread to other parts of the body (metastatic). The study aims to determine if patritumab deruxtecan (also called HER3-DXd or MK-1022) helps patients live longer overall or without the cancer growing compared to chemotherapy or trastuzumab deruxtecan. This is a Phase 3 clinical trial focusing on this particular type of breast cancer. Participants receive one of several treatments: patritumab deruxtecan through intravenous infusion, chemotherapy options like paclitaxel or nab-paclitaxel via IV, oral capecitabine tablets, liposomal doxorubicin via IV, or trastuzumab deruxtecan via IV infusion. The study compares the effects of patritumab deruxtecan alone to the treatment chosen by the physician. Treatments are administered according to standard dosing schedules during the trial. During the study, participants are monitored for how long they live without the cancer progressing (up to about 45 months) and overall survival (up to about 85 months). Researchers assess disease status through imaging and other evaluations. Participants have regular check-ups to monitor health, treatment effects, and any side effects. The study tracks treatment response and safety over the extended follow-up period to understand the benefits and risks of the therapies.

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 the safety and effectiveness of trontinemab in people aged 50 to 90 with early symptoms of Alzheimer's disease, ranging from mild cognitive impairment to mild dementia. This Phase III clinical trial focuses on those who show evidence of Alzheimer's pathology and have a recent history of cognitive decline. The study aims to measure changes in cognitive function over 72 weeks. Participants will be randomly assigned to receive either intravenous trontinemab or a placebo. The trial is designed as a double-blind, placebo-controlled study, meaning neither participants nor researchers know who receives the active drug or placebo. The treatment period lasts up to 72 weeks, during which participants will undergo various assessments to monitor their cognitive status and safety. During the study, participants will complete clinical tests including cognitive assessments and imaging such as MRI, PET scans, or cerebrospinal fluid analysis to confirm Alzheimer's pathology. A study partner will assist participants as needed. Researchers will track changes from the start of the study through week 72 using tools like the Clinical Dementia Rating. Safety monitoring and adherence to study procedures will also be closely observed throughout the trial.

Researchers are evaluating the efficacy, safety, and tolerability of zorevunersen in patients with Dravet syndrome, a condition marked by reduced levels of the Nav1.1 protein due to mutations in the SCN1A gene. Zorevunersen is an investigational antisense oligonucleotide designed to increase the expression of the sodium channel Nav1.1 protein by boosting the production of its messenger RNA. This Phase 3, multicenter, randomized, double-blind, sham-controlled study aims to assess the potential of zorevunersen for disease modification by measuring changes in major motor seizure frequency and other health outcomes. The study has two treatment periods. In Treatment Period 1, participants assigned to zorevunersen receive the drug by intrathecal administration on Day 1, Day 57, Day 169, and Day 281 with doses of 70 mg initially and then 45 mg later. The sham group undergoes a procedure mimicking drug administration without receiving the drug. In Treatment Period 2, those initially on zorevunersen receive 45 mg doses on Day 393, Day 477, and Day 589. Participants initially in the sham group are then given zorevunersen doses of 70 mg on Day 393 and Day 477, and 45 mg on Day 589. Participants will be closely monitored throughout the study with a primary focus on seizure changes measured at Week 28. Secondary assessments include behavior, cognition, clinical status, and quality of life. The study includes an initial 8-week baseline period and a 6-week observation period to confirm seizure frequency and stability of other treatments. Patients may continue to an open-label extension study to receive zorevunersen if eligible. The study involves children aged 2 to under 18 years and tracks safety and tolerability alongside efficacy outcomes.

Researchers are evaluating the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of a drug called S230815 in children aged 2 to 12 years who have Developmental Epileptic Encephalopathy caused by specific genetic changes in the KCNT1 gene. This is a Phase Ib/II, first-in-human, multicenter, open-label study focusing on this rare and severe form of epilepsy. The study includes two main parts. Part 1 involves giving participants increasing doses of S230815 through injection to determine the best dose. After completing Part 1, participants may enter Part 2, a long-term extension where they continue receiving their assigned dose of S230815 for up to 72 weeks. Participants will be closely monitored throughout the study for side effects and drug levels. Researchers will collect safety information, including any adverse events, for up to 116 weeks. Genetic testing confirms eligibility, and participants will undergo various assessments during the screening and treatment periods to evaluate the drug's effects and safety over time.

Primary immune thrombocytopenia (ITP) is a condition in which the immune system mistakenly destroys platelets, the cells that help stop bleeding. This leads to a low platelet count, making it easier to bruise or bleed. The trial investigates the long-term safety, tolerability, and effectiveness of mezagitamab in adults with chronic primary ITP who have previously participated in certain mezagitamab studies. It also examines how the body processes mezagitamab over time. Participants who completed the previous mezagitamab studies TAK-079-3002 or TAK-079-1004 and meet specific criteria will receive mezagitamab as a subcutaneous injection during this continuation study. The study is open-label and multicenter, focusing on continued treatment based on protocol requirements. The medication is given under medical supervision, and participants return to the study clinic several times throughout the study. During their participation, individuals will undergo regular assessments including monitoring for treatment-emergent adverse events and serious adverse events up to approximately 108 weeks. Researchers will track safety by noting any adverse events that lead to permanent withdrawal from mezagitamab. The study includes physical evaluations, laboratory tests, and ongoing safety monitoring to understand how well participants tolerate the treatment and how effective it is over the long term.
