There are about 2700 clinical studies being (or have been) conducted in Bulgaria. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Crohn's Disease (CD) is a gastrointestinal disease that can cause chronic diarrhea with or without gross bleeding, abdominal pain, weight loss, and fever. This study will assess the pharmacokinetics, efficacy, and safety of risankizumab in pediatric participants with moderately to severely active CD aged 2 to < 18 years old who have had intolerance or inadequate response to other therapies. Risankizumab is an approved drug for adults with plaque psoriasis, psoriatic arthritis, and CD and is being developed for the treatment of CD in pediatrics. This study is comprised of 3 cohorts that may participate in 3 substudies (SS). Cohort 1 will enroll participants with ages from 6 to less than 18 years. Cohort 2 will enroll participants with ages from 2 to less than 6 years. Cohort 3 will enroll participants with ages from 2 to less than 18 years. SS1 is an open-label induction period where participants will receive a weight-based induction regimen of risankizumab. SS2 is a double-blind maintenance period where participants will be randomized to receive 1 of 2 doses of weight-based induction regimen of risankizumab. SS3 is an open-label extension period where participants will receive risankizumab based off of their response in SS2. Around 110 pediatric participants with CD will be enrolled at around 100 sites worldwide. Participants in SS1 will receive risankizumab intravenously during the 12-week induction period. Participants in SS2 will receive risankizumab subcutaneously during the 52-week randomized maintenance period. Participants in SS3 will receive risankizumab subcutaneously during the 208-week open label period. Participants will be followed-up for approximately 140 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
This prospective longitudinal study will follow participants with Multifocal Motor Neuropathy over time and collect data on their clinical outcomes, quality of life, and use of health care resources. Participants will follow their regular visit schedule with their treating physician, except for an optional second visit occurring 7 to 14 days after the start of the study to collect biomarker data. No IMP will be administered.
The purpose of this study is to measure the long-term safety and tolerability of ianalumab in participants with Sjogrens syndrome who have previously completed treatment from one of two NEPTUNUS 1 year core studies (CVAY736A2301 or CVAY736A2302). - The study treatment is ianalumab 300 mg in a 2 mL pre-filled syringe for injection. All participants will receive ianalumab either monthly or every 3 months. - The treatment duration will be 3 years with an additional up to 2-year safety follow-up. The total duration of this extension study will be up to 5 years. - The visit frequency will be monthly during both the treatment period and mandatory follow-up, and then less frequently during the subsequent conditional follow-up Treatment of interest: The randomized treatment (ianalumab) will be received monthly or every 3 months. Participants assigned to treatment every 3 months will receive placebo every month between the ianalumab doses to maintain blinding. Number of Participants: Approximately 600 participants from the NEPTUNUS core studies will be rolled over into the extension study. Treatment Groups:There will be no screening period in this trial. From Week 48 of the NEPTUNUS core study, participants will be given the opportunity to consent to this extension study. From Week 52 of the NEPTUNUS core studies (i.e., Day 1 in the extension study), eligible participants will be assigned to either one of the treatment regimens: - ianalumab 300 mg monthly or - ianalumab 300 mg once every 3 months Participants receiving placebo in either of the NEPTUNUS core studies will be randomized 1:1 to receive ianalumab 300 mg monthly or every 3 months starting from Week 60 and participants receiving ianalumab in either of the NEPTUNUS core studies will continue the same treatment in the extension study. Ianalumab will be given as a subcutaneous injection from a 2 mL pre-filled syringe. Participants will be given the opportunity to self-inject at home on some visits after receiving training.
This is a Phase 3 global, multicenter, 52-week, open-label extension (OLE) rollover study for subjects completing study CN012-0026 or CN012-0027. Subjects (randomized or non-randomized) who complete the 38-week CN012-0026 or CN012-0027 study will be eligible to enroll in CN012-0028. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with psychosis associated with Alzheimer's Disease.
The purpose of this study is to measure the long-term safety and tolerability of efgartigimod PH20 SC in adult participants with IIM who previously participated in ARGX-113-2007. Secondary objectives include efficacy measures of efgartigimod PH20 SC in participants with IIM.
The purpose of this study is to assess the clinical efficacy, safety, PK, and PD of multiple dose levels of ESK-001 compared with placebo in adult patients with SLE.
This is a randomized, double-blind parallel-group, placebo-controlled study. that will last 40 weeks and will focus on Quality of Life.36 Subjects with stage IV metastatic colorectal cancer will be referred for study inclusion. Patients will be randomly assigned (1:1 ratio) to take 2 ml of LentinexHP or placebo orally twice a day (a total of 6 mg). Products will be dispensed to allow administration of the product for six weeks. Each bottle of LentinexHP or placebo contains 30 mL, which at 1.5 mg/mL will provide dosage for approximately five days. The patients will periodically complete the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) Quality of Life (QoL) instrument, the short form 36 (SF-36), the Fatigue Symptom Inventory (FSI), and the QoL questionnaire used in the previous LentinexHP QoL study.
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm within the study will be 7 years.
The improvement or preservation of quality of life (QoL) is one of the three pillars of the European Union (EU) Mission on Cancer, which underpins the needs of patients from cancer diagnosis throughout treatment, survivorship, and advanced terminal stages. Clinical studies and real-world data show that the use of Patient Reported Outcome Measures (PROMs) for QoL assessment in routine oncology practice has positive effects on patient wellbeing and healthcare resource utilization. However, full implementation of PROMs is not yet part of standard of care and is not adequately considered in cancer policies and programs. A comprehensive tool incorporating the perspective of patients at different stages of the disease trajectory and widely applicable across Europe is still lacking. The European Oncology Quality of Life Toolkit (EUonQoL-Kit) is a unified patient-centred tool for the assessment of QoL, developed from preferences and priorities of people with past or current cancer experience. The EUonQoL-Kit includes three electronic questionnaires, specifically designed for different disease phases (patients in active treatment, survivors, and patients in palliative care), available in both static and dynamic (Computer Adaptive Testing, CAT) versions and in several European languages. This is a multicentre observational study, with the following aims: - The primary aim is to perform the psychometric validation of the EUonQoL-Kit. - Secondary aims are to assess its acceptability, to validate the static and dynamic versions against each other, and to provide estimates of QoL across European countries. The EUonQoL-Kit will be administered to a sample of patients from 45 European cancer centres. The sample will include patients in active treatment (group A), survivors (group B), and patients in Palliative Care (group C). Each centre will recruit 100 patients (40 from group A, 30 from group B, 30 from group C), for an overall sample size of 4,500 patients (at least 4,000 patients are assumed to be enrolled, due to an expected lower recruitment rate of 10-15%). Three sub-samples of patients (each corresponding to 10% of the total sample for each centre) will fill in an additional questionnaire: - FACT-G (Functional Assessment of Cancer Therapy - General) and EQ-5D-5L (5-level European Quality of Life Five Dimension), to test concurrent validity. - Live-CAT version, to validate the static and dynamic versions against each other. - EUonQoL-Kit, at least 1 hour after the first completion, to assess test-retest reliability.
