Researchers are evaluating the safety, pharmacokinetics, pharmacodynamics, and effectiveness of an investigational drug called GNR-055 in patients with Mucopolysaccharidosis Type II MPS II, also known as Hunter syndrome. This condition is a genetic disorder caused by a deficiency of the enzyme iduronate-2-sulfatase ID2S, leading to harmful buildup of certain substances in cells that affects growth, organs, and the nervous system. The study is a phase 23, multicenter, open-label trial involving different age groups to better understand how GNR-055 works and its safety profile. GNR-055 is a modified enzyme replacement therapy designed to cross the blood-brain barrier, potentially preventing neurological damage and improving quality of life for patients with MPS II. Participants receive weekly intravenous infusions of GNR-055 at doses ranging from 1.0 to 3.0 mgkg, depending on their study group. The study includes multiple cohorts, with adult and pediatric patients receiving specific dosing regimens over the trial period. During the study, participants will undergo various assessments including monitoring of adverse events, urine and serum levels of glycosaminoglycans GAG, cerebrospinal fluid analysis, joint motion measurements, MRI scans of liver, spleen, and brain, heart and lung function tests, neurocognitive evaluations, and biomarker analysis. These evaluations occur at baseline and multiple follow-up visits up to week 56. The study aims to gather detailed data on the drugs impact on disease symptoms, safety, and biological markers to inform future treatment options.

Researchers are evaluating the tolerability, safety, and effectiveness of a gene therapy called GNR-097 for boys aged 4 to 9 years with Duchenne muscular dystrophy DMD. The study includes two phases Phase I involves two dose groups receiving increasing amounts of the gene therapy, and Phase II is a randomized, single-blind, placebo-controlled study where some participants receive placebo initially with the option to receive gene therapy in the second year. Participants will receive a single intravenous infusion of GNR-097 on Day 1 during Phase I. In Phase II, participants randomized to placebo will receive a matching placebo infusion on Day 1, then have the option to receive the gene therapy infusion at the start of the second year. The study aims to determine the best dose in Phase I and assess safety and efficacy in Phase II with placebo control. Throughout the study, participants will be monitored for adverse events and safety from baseline through Week 104. Researchers will evaluate treatment-emergent adverse events, serious adverse events, and adverse events of special interest. Participants will undergo assessments of functional activity and immune response, and their health will be tracked during screening, treatment, and follow-up periods. The total study duration spans up to approximately four years from the start date in 2025 to completion in 2029.

Researchers are studying aggressive high-volume metastatic hormone-sensitive prostate cancer mHSPC in male patients in the Russian Federation. This observational study focuses on treatment patterns and the evaluation of homologous recombination repair mutations HRRm in circulating tumor DNA ctDNA. The study aims to better understand demographic and clinical characteristics along with how patients with different HRR gene statuses are treated. The study enrolls about 400 male patients with high-aggressive Gleason 8-10 and high-volume mHSPC who have known tumor HRRm status from routine tumor samples. No additional procedures beyond routine clinical care are performed. Data are collected during two visits a baseline visit where medical history and treatment approaches since diagnosis are recorded, and a final visit at disease progression or after about 12 months to gather follow-up treatment and progression information. Blood samples for ctDNA and HRRm testing are collected from routine blood draws and analyzed centrally. Participants contribute data through medical record reviews and, if needed, patient interviews. Researchers collect information on treatments received, disease progression, lab tests, and mutation presence. The study evaluates various outcomes including treatment proportions, therapy durations, progression times, and mutation rates over 36 months. Data are entered into electronic forms, and follow-up may occur by phone if in-person visits are not possible. The total study duration is about 38 months or until all data are collected.

This research aims to assess the physical impact of Multiple Sclerosis MS from the participants perspective. It also provides participants continued access to the medication ocrelizumab while evaluating its safety and tolerability. The study is an open-label extension phase 3 trial sponsored by Hoffmann-La Roche, focusing on patients previously enrolled in related studies who currently lack local access to ocrelizumab treatment. Participants will receive ocrelizumab either as a 600 mg intravenous infusion or a 920 mg subcutaneous injection, following the dosing schedule established in their prior parent study. Treatment will continue until local access to the drug becomes available, if safety concerns arise, if the participant withdraws consent, or in the event of death. During the study, participants will be monitored for changes in physical functioning using patient-reported outcome measures over up to five years. Researchers will also track the number of participants receiving ocrelizumab and monitor adverse events, including serious or special interest events that may lead to discontinuation. Safety and tolerability assessments will continue throughout the study duration, which may last up to five years.

Researchers are conducting a national, multi-center, prospective study to collect real-world data on patients in the Russian Federation with advanced and aggressive endometrial cancer, specifically stage III-IV disease. The study focuses on molecular profiling markers such as POLE mutations, dMMRpMMR, p53 abnormalities, HER2 expression, and PD-L1 status, alongside demographic and clinical characteristics. It aims to understand first-line postoperative treatment approaches in these patients. The study involves no additional procedures beyond routine clinical practice. Patients provide archival tumor tissue samples obtained from biopsy or post-operative formalin-fixed paraffin-embedded FFPE blocks for molecular testing. Testing uses immunohistochemistry IHC for certain markers and next-generation sequencing NGS or polymerase chain reaction PCR for POLE mutations. Data will be collected at two visits a baseline visit to gather clinical and demographic information and tissue testing results, and a final visit 6 months later or at disease progression to collect follow-up treatment and progression data. Participants data and outcomes will be recorded in an electronic case report form. The study measures include rates of positive molecular markers and various clinical and treatment-related outcomes over 24 to 33 months. Approximately 500 patients will be enrolled across about 30 sites. The overall study duration is about 27 months or until data collection for all patients is complete.

This study evaluates the long-term safety and tolerability of pelacarsen TQJ230 in people with established cardiovascular disease and elevated Lipoproteina who completed a previous related study. It is an open-label extension trial, meaning all participants receive the study drug without placebo comparison.
