Researchers are investigating new treatments for rheumatoid arthritis (RA), a condition where current therapies like methotrexate (MTX) may not fully control symptoms for many people. This Phase 2b study evaluates a medicine called tulisokibart to see if it can better reduce RA symptoms in individuals already taking MTX. The trial aims to determine if one or more doses of tulisokibart work better than a placebo, which looks like the medicine but contains no active drug. The study includes a 12-week period where participants receive either tulisokibart or a placebo by subcutaneous injection while continuing their MTX treatment, which can be given by injection or orally. Following this, there is a long-term extension lasting 116 weeks, composed of a 44-week main extension and a 72-week optional extension, to further assess the medication's effects and safety over time. Participants will undergo assessments to measure treatment response, including the American College of Rheumatology 20% response criteria at week 12 to gauge symptom improvement. Throughout the study, researchers will monitor for safety and effectiveness, with evaluations extending through the long-term extension periods, totaling over two years of participation.

Crohn's disease is a chronic inflammatory condition affecting the digestive tract that currently has no cure. This research aims to evaluate the safety and effectiveness of upadacitinib in treating moderate to severe active Crohn's disease in a real-world setting in Japan. The study will monitor any adverse events and changes in disease activity among participants. All participants will receive upadacitinib as prescribed by their doctors following local approved guidelines. Around 240 participants will be enrolled, and treatment will be according to each participant's usual clinical care. The study is observational and non-interventional, meaning no additional treatments or procedures beyond standard care will be required. Participants will be followed for up to 64 weeks, with study visits conducted either in person or virtually according to standard care practices. Researchers will assess safety by tracking serious infections related to the drug and monitor disease activity throughout the study period. There is expected to be no extra burden on participants beyond their routine care and assessments.

Researchers are evaluating the long-term safety and effectiveness of pembrolizumab (MK-3475) in participants with advanced solid tumors or blood cancers who have previously taken part in other pembrolizumab-based studies. This phase 3 study includes participants who are either currently on treatment or in follow-up from prior parent studies. It aims to understand how well pembrolizumab works over an extended period, up to approximately 10 years, by observing overall survival and safety outcomes. The study has three phases: First Course Phase, Survival Follow-up Phase, and Second Course Phase. Participants who were receiving pembrolizumab, pembrolizumab-based combinations, or lenvatinib in their parent studies will continue treatment in the First Course Phase, completing up to 35 doses every 3 weeks or 17 doses every 6 weeks. Those in the Follow-up Phase will enter the Survival Follow-up Phase without additional treatment but will be monitored. Participants eligible for a Second Course Phase, who have not received other anticancer treatments since their prior pembrolizumab dose and meet health criteria, may receive up to 17 doses every 3 weeks or 8 doses every 6 weeks of pembrolizumab or its combinations. Some may also receive other study drugs such as olaparib, MK-4280, MK-4280A, or pembrolizumab with berahyaluronidase alfa. Participants will be involved in regular treatment visits, safety checks, and long-term monitoring for up to about 10 years to assess overall survival. Researchers will evaluate clinical outcomes, monitor any side effects, and check organ function and physical health status. The study includes detailed eligibility screening, including physical assessments and adherence to contraception requirements for women of childbearing potential. Safety follow-up is ongoing to ensure participant well-being throughout the study.

This research observes patients with Paroxysmal Nocturnal Hemoglobinuria who are treated with Fabhalta capsules. It is a multicenter, single-arm, non-interventional study designed to monitor drug use and safety over time. The study uses a central registration and all-case surveillance system to collect data. Participants will be observed for 48 weeks after starting Fabhalta treatment. If treatment stops within this period, any adverse events and use of other medications will be tracked up to 30 days after the last treatment day. There are no additional interventions or comparison groups in this study. During the study, researchers will monitor the occurrence of infections and other adverse events through case report forms. Participants' health and drug usage will be recorded throughout the observation period. The total participation lasts for 48 weeks, focusing on safety and drug use in real-world settings.

Researchers are evaluating treatments for patients with locally recurrent rectal cancer who have not previously received radiation. This phase III randomized trial in Japan started in August 2019 and aims to compare local relapse-free survival between two approaches: standard surgery plus adjuvant chemotherapy and preoperative chemoradiotherapy followed by surgery plus adjuvant chemotherapy. The study plans to enroll 110 patients over six years from 43 institutions, focusing on whether adding chemoradiotherapy before surgery improves outcomes. Participants will be randomly assigned to one of two treatment groups. One group will undergo surgery followed by adjuvant chemotherapy using regimens such as CAPOX, mFOLFOX6, capecitabine, or 5-FU plus leucovorin. The other group will receive preoperative chemoradiotherapy consisting of capecitabine and radiation therapy before surgery, followed by adjuvant chemotherapy. Surgery will be performed within 42 days of registration for the surgery-first group, and between 56 and 98 days after completing chemoradiotherapy for the other group. Surgical procedures aim to achieve clear margins and may include various types of rectal and pelvic surgeries. Throughout the study, participants will be monitored for local relapse-free survival over three years as the primary outcome. Secondary outcomes include overall survival, relapse-free survival, rates of local and distant relapse, complete tumor removal rates, response to preoperative treatment, treatment completion rates, adverse events, and quality of life after surgery. Patients will undergo imaging tests, pathological assessments, and clinical evaluations to track disease status and treatment effects. The total study duration per participant includes treatment and follow-up assessments to measure long-term outcomes and safety.
