Researchers are evaluating the effects of EYU688, an oral drug, compared with a placebo in patients with dengue fever. The study aims to understand how EYU688 influences dengue viral load, fever clearance time, and clinical symptoms. This randomized, participant- and investigator-blinded, placebo-controlled trial includes two patient groups based on different pharmacokinetic sampling schedules. Participants will receive either EYU688 or a matching placebo orally. The study runs two cohorts in parallel one with intensive pharmacokinetic sampling and another with sparse sampling. Treatment and assessments occur from the start of dosing through Day 15, with additional safety monitoring up to Day 35. The study measures drug concentration levels and viral load changes over time. Throughout the study, participants will undergo evaluations including viral load tests, fever monitoring, blood tests for blood cells and liver enzymes, and assessments for dengue severity. Safety and adverse events are recorded up to Day 35. The primary outcome is viral load reduction at 48 hours after treatment begins. Participation lasts until study completion, expected by July 2027.

Migraines cause severe throbbing or pulsating headaches, often on one side of the head, and are linked with nausea and sensitivity to light and sound. This study evaluates Corabotase IPN10200, a medication designed to prevent episodic and chronic migraines by blocking the release of chemicals that cause pain. The research aims to assess the safety, optimal dosing, and effectiveness of Corabotase injections into head and neck muscles. The trial has three periods an initial screening to confirm participant eligibility Step 1, where two doses of Corabotase are tested sequentially in separate cohorts against placebo, with injections administered into head, face, and neck muscles, and safety monitored for 36 weeks and Step 2, where new participants with episodic or chronic migraine are randomly assigned to receive either Dose A, Dose B, or placebo, with injections given in the same muscle areas and both safety and effectiveness tracked until Week 36. Participants complete a daily electronic migraine diary and questionnaires throughout the study, which lasts up to 44 weeks. Researchers monitor adverse events, lab and vital sign changes, facial exams, ECG readings, suicidal behavior, and antibody responses. The main outcome is the reduction in monthly migraine days by Week 12, with ongoing evaluation of headache frequency, medication use, and safety measures through Week 36.

Researchers are evaluating the safety and effectiveness of AlloNK, a non-genetically modified allogeneic natural killer NK cell therapy derived from cord blood, combined with rituximab, in people with relapsing forms of B-cell dependent rheumatologic diseases. These diseases include refractory rheumatoid arthritis, Sjgrens disease, idiopathic inflammatory myopathies, and systemic sclerosis. This open-label Phase 2a study aims to explore treatment options for patients whose conditions have not responded well to previous therapies. Participants receive AlloNK after a conditioning regimen, followed by rituximab. AlloNK is an off-the-shelf, cryopreserved NK cell therapy given in combination with rituximab. The treatment period lasts up to 104 weeks, during which participants are monitored for safety and clinical response. The study includes one treatment group receiving this combination therapy. Throughout the study, participants undergo regular assessments to evaluate safety from enrollment until the end of treatment at Week 104. Researchers measure disease-specific outcomes at Week 52, including disease activity scores for rheumatoid arthritis, Sjgrens disease activity indices, improvement scores for inflammatory myopathies, and response indices for systemic sclerosis. The study involves clinical evaluations, laboratory tests including inflammatory markers, and joint assessments to monitor treatment effects and safety over the extended period.

Researchers are evaluating the effects of remibrutinib compared to continuous ocrelizumab treatment in people living with relapsing multiple sclerosis RMS. This Phase 3b study aims to provide data on the efficacy, safety, and tolerability of remibrutinib when patients switch from ocrelizumab. The trial is randomized, open-label, and conducted across multiple centers globally, including the USA. Participants in the study are assigned to either switch to remibrutinib tablets taken orally or continue with ocrelizumab administered via infusion or injection at standard doses. The study includes a Core Part lasting up to 24 months, during which these treatments are compared. Those completing the Core Part may enter an Extension Part lasting up to 24 months, where all participants receive remibrutinib in an open-label format. Throughout the study, participants will undergo regular monitoring including MRI scans to measure new or enlarging T2 lesions and assessments for disease activity and adverse events. The main outcome is the annualized rate of new or enlarging T2 lesions during the Core Part, with continued evaluations during the Extension Part. Safety and tolerability are closely monitored, and total participation can last up to 48 months.

Researchers are evaluating trastuzumab deruxtecan T-DXd for adults with unresectable or metastatic breast cancer that is either HER2-low or HER2 IHC 0. This includes patients with hormone receptor-negative and hormone receptor-positive types. The study aims to assess the safety and effectiveness of T-DXd, focusing on how long patients benefit from this treatment before needing the next anticancer therapy. Participants receive T-DXd intravenously at a dose of 5.4 mgkg on the first day of each 21-day cycle. Treatment continues until disease progression, unacceptable side effects, other criteria for stopping, or two years after the first dose. The study includes four groups based on hormone receptor status and HER2 classification, with participants having had one to two prior treatments for metastatic breast cancer. During the study, participants will have regular assessments including imaging scans to measure tumors, blood tests to monitor organ function, and questionnaires to evaluate quality of life. Researchers will track the time to next treatment, progression-free survival, response rates, adverse events, and changes in patient-reported outcomes for up to 24 months. Safety monitoring and close follow-up will support participant well-being throughout the trial.
