Researchers are evaluating the effectiveness of delgocitinib cream 20 mg/g applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis (PPP). This phase 2a, double-blind, two-arm trial focuses on adults diagnosed with PPP, a condition characterized by persistent pustules on the palms and/or soles, lasting more than three months. The study aims to assess skin improvement using the PPP Area and Severity Index (PPPASI) and other clinical evaluations over 16 weeks. Participants will be randomly assigned to apply either delgocitinib cream or the cream vehicle twice daily during a 16-week treatment period. The study involves approximately 9 visits over about 18 weeks in total. The trial is designed to compare the two treatments' effects on PPP severity, with a thorough monitoring process throughout the study period. During the trial, participants will undergo clinical assessments including photographic evaluations to confirm PPP diagnosis, PPPASI scoring to measure skin improvement, and physician global assessments. Safety and treatment adherence will be closely monitored. The main outcome measure is the number of participants achieving at least a 75% improvement in PPPASI score from baseline at week 16. The study also includes safety checks and follow-up to ensure participant well-being throughout the trial.

Researchers are studying advanced renal cell carcinoma (RCC) that has returned after prior adjuvant therapy. The trial aims to find out if treatment with belzutifan and zanzalintinib helps patients live longer and delays disease progression compared to treatment with cabozantinib. This is a Phase 3 randomized study focusing on participants with recurrent advanced RCC who have previously received anti-PD-1/L1 therapy. Participants are randomly assigned to receive one of two oral drug regimens: either belzutifan combined with zanzalintinib, both taken once daily, or cabozantinib alone, also taken once daily. The study compares these treatments to assess their effects on disease control and overall survival. During the study, participants will be monitored for progression-free survival and overall survival for up to approximately 73 months. Researchers will evaluate how well the cancer responds to treatment and track any changes in health status over time. Safety and effectiveness of the treatments will be closely followed throughout the study period.

Researchers are studying oligodendrogliomas, a type of brain tumor identified by specific genetic changes such as IDH1 or IDH2 mutations and 1p/19q co-deletion. These tumors are classified as CNS WHO grade 2 or 3, and the study aims to determine the best treatment approach to improve survival while preserving brain function and quality of life. This phase 3 trial compares current standard treatments because existing data is unclear about the best timing and combination of chemotherapy and radiotherapy for these tumors. The study compares two treatment approaches for adults with newly diagnosed grade 2 or 3 oligodendrogliomas. One group receives an initial chemotherapy regimen of lomustine and temozolomide (CETEG) with delayed radiotherapy plus PCV chemotherapy at progression. The other group receives standard radiotherapy followed by PCV chemotherapy. Radiotherapy doses vary based on tumor grade. The study plans to assess if delaying radiotherapy and adjusting chemotherapy can maintain survival while reducing side effects. Participants will undergo regular monitoring including MRI scans every three months, neurological assessments, quality of life questionnaires, and annual cognitive testing. Researchers will measure qualified overall survival, defined as survival without decline in function, cognition, or quality of life. The study will last up to 10 years, with close tracking of side effects, tumor response, and patients' well-being to determine the best balance of treatment effectiveness and quality of life.

The purpose of this study is to assess the long-term safety and tolerability after an intravitreal injection (a shot of medicine into the eye) of JNJ-81201887 administered in parent clinical studies.

Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common inherited neuropathy caused by a gene duplication affecting PMP22. Symptoms usually begin in early childhood and progress variably. Currently, there is no established therapy, and early treatment before nerve degeneration is crucial. Researchers found that gene expression changes in young CMT1A rats predicted disease severity later in life, and similar gene changes were seen in adult CMT1A patients, supporting a translational approach to identify biomarkers in young patients. This study involves children, adolescents, and young adults aged 10 to 30 years with CMT1A. It includes a multi-omic analysis of tissue samples from young CMT1A rats to find early markers of disease severity. In parallel, patients will be assessed over 12 months using new clinical scores (CMTES-R and CMTNSv2-R), functional outcome measures, nerve conduction studies, and quantitative MRI. Blood and optional skin samples will be collected to measure gene expression markers originally identified in rats. Participants will undergo repeated clinical evaluations, nerve studies, imaging, and provide blood and possibly skin samples. Patient-reported outcomes on pain, fatigue, cramps, and quality of life will also be collected. The main outcomes measured are changes in the CMT Examination Score Rasch Analysis and the CMT Neuropathy Score Version 2 Rasch Analysis after 12 months. This comprehensive approach aims to establish biomarkers to predict disease course and enable effective early clinical trials.

Researchers are evaluating the clinical utility of serum neurofilament light (sNfL) as a prognostic marker for disease activity in patients with relapsing multiple sclerosis (MS). This prospective, multicenter, observational, non-interventional study in Germany aims to understand how sNfL values can influence patient management and treatment decisions. The study focuses on patients treated with category 1 disease-modifying therapies (DMTs) who have incorporated sNfL testing into their care. Participants will either continue their current category 1 DMT, which includes therapies such as dimethylfumarate, glatiramer acetate, interferon beta, and teriflunomide, or switch to ofatumumab based on their physician’s clinical judgment. There is no treatment allocation by the study itself. Data collection will cover up to 24 months, and the frequency of visits and assessments will follow routine clinical practice without a fixed protocol. During the study, baseline and follow-up data will be gathered according to standard care recommendations, including clinical evaluations and sNfL measurements. Researchers will monitor the proportion of patients with high sNfL levels over time to assess disease activity. The observational period is flexible and guided by the treating physician, with no additional diagnostic or monitoring procedures beyond standard care. Participants will be followed for up to two years to better understand how sNfL influences treatment management in relapsing MS.

Researchers are evaluating the real-world effectiveness, safety, and tolerability of ribociclib combined with an aromatase inhibitor, with or without luteinizing hormone-releasing hormone (LHRH) therapy, for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. The study also compares data from patients treated with abemaciclib plus endocrine therapy with or without LHRH, and those receiving endocrine monotherapy with or without LHRH. This observational study aims to understand treatment decisions and clinical use of ribociclib after its approval, collecting socio-economic data, quality of life, and patient compliance information. Participants receive treatment based on their physician's clinical judgment without study-assigned interventions. The treatments observed include ribociclib with an aromatase inhibitor LHRH, abemaciclib with endocrine therapy LHRH, or endocrine monotherapy LHRH. The study is conducted in various breast cancer centers and gynecological practices in Germany and Austria to represent local healthcare settings. Participants undergo assessments to monitor treatment effectiveness, safety, quality of life, and adherence to therapy over time. Data collected include clinical outcomes, adverse events, socio-economic status, and patient-reported compliance. The primary outcome measured is invasive disease-free survival over 36 months. This information will help inform clinical decision-making and improve outcomes for patients with early breast cancer in routine practice.

Researchers are assessing the effectiveness of avapritinib (BLU-285) in managing indolent systemic mastocytosis (ISM) among patients in Germany. This non-interventional study aims to fill gaps in understanding the natural history and treatment outcomes of ISM, particularly in participants whose symptoms are not adequately controlled with current symptomatic treatments. The study observes participants in real-world clinical settings without altering their standard care. Avapritinib is given as an oral tablet, and treatment decisions are made by healthcare providers as part of routine care for those with moderate to severe ISM symptoms. Participants start avapritinib treatment at the provider's discretion, following approved prescribing guidelines. No other interventions are assigned by the study, emphasizing observation of usual care in a real-world environment. Participants are followed for up to 24 months, during which researchers monitor changes in quality of life related to mastocytosis using the Mastocytosis Control-quality of Life (MC-QoL) Questionnaire, assessed at the start and at 6 months. The study also collects data on symptom control and safety, focusing on participants who have not previously used avapritinib. This long-term observation helps understand treatment effectiveness and patient experiences over time.

Researchers are monitoring the long-term safety of efgartigimod, a biological treatment, in patients with generalized myasthenia gravis (gMG). This study is a non-interventional, prospective, post-authorization safety study designed to observe patients who are either starting or already receiving efgartigimod, as well as those with gMG who have not been treated with it. The study aims to compare the occurrence of serious infections and other safety outcomes over a period of up to 10 years. Patients with gMG who are expected to begin efgartigimod treatment at enrollment or who are currently in their first treatment cycle will be included in the efgartigimod group. Those with gMG who are not starting efgartigimod and have never received it will be enrolled in a non-efgartigimod group. There are no assigned treatments or interventions from the researchers; the study simply observes patients as they receive routine care. Participants will be followed for up to 10 years to track safety outcomes, including serious infections. Data collection will involve routine clinical assessments and monitoring as per standard medical practice. The study observes the real-world use of efgartigimod and its safety profile in managing gMG, providing valuable long-term information without altering patients' treatment plans.

Researchers are evaluating the recurrence-free survival of women with advanced HRD-positive high-grade ovarian cancer, fallopian tube cancer, primary peritoneal cancer, and clear cell carcinoma of the ovary after complete tumor removal. This phase II, randomized, open-label study compares two treatment strategies involving chemotherapy and maintenance therapy with niraparib. The study focuses on patients with no residual tumor mass following primary tumor debulking and aims to determine if fewer cycles of chemotherapy followed by niraparib maintenance are as effective as the standard number of chemotherapy cycles plus niraparib. Participants are randomly assigned to one of two groups: one receiving 3 cycles of carboplatin plus paclitaxel chemotherapy followed by niraparib maintenance, and the other receiving 6 cycles of carboplatin plus paclitaxel followed by niraparib maintenance. Randomization is based on genetic analysis and disease stage. Tumor assessments using CT or MRI scans will be done at defined intervals after treatment starts and during maintenance. Blood markers and safety monitoring will be conducted regularly throughout the treatment period. During the study, patients will have clinical visits every 3 weeks during chemotherapy and monthly during the first 11 months of maintenance, then quarterly thereafter. Safety is monitored continuously through adverse event reporting. The study plans to enroll 640 patients across about 60 sites in six European countries over 36 months. The primary outcome measured is recurrence-free survival over 8 years.
