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.
The primary objective of this study is to observe the long-term safety of filgotinib in adults who have completed or met protocol specified efficacy discontinuation criteria in a prior filgotinib treatment study in ulcerative colitis (UC).
The study is a prospective, randomized controlled phase III trial, to test the efficacy, safety and neurocognitive outcomes of advanced NSCLC patients, following stereotactic radiosurgery (SRS) for 1 inoperable brain metastasis or 2-10 brain metastases, treated with NovoTTF-200M and supportive treatment compared to supportive treatment alone. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields or TTF) to the region of the malignant tumor, by means of surface, insulated electrode arrays.
This is a First in Human study to assess the feasibility, safety and effectiveness of the Zenflow Spring System in relieving the symptoms of obstructive Benign Prostatic Hyperplasia (BPH).
Young men who have sex with men (MSM) in low- and middle-income countries often do not seek out HIV testing, are unaware of their HIV-positive status, and do not receive early medical care, compromising their health and contributing to downstream disease incidence. This situation is of great concern in post-socialist countries of Eastern Europe, where stigma about HIV/AIDS and same-sex behavior are great, HIV epidemics are still increasing, and the health needs of young MSM are rarely acknowledged or addressed. The planned research will be conducted in Sofia, Bulgaria, where MSM account for nearly half of HIV infections. The study will be conducted in two phases.
The purpose of this study was to assess efficacy, including inhibition of radiographic progression, and safety with upadacitinib versus placebo and versus an active comparator, adalimumab, in adults with with moderately to severely active rheumatoid arthritis (RA) who are on a stable background of methotrexate (MTX and who have an inadequate response to MTX.
The main aim of the study is to check for long-term side effects of Vedolizumab Subcutaneous (also known as Vedolizumab SC) in people with ulcerative colitis and Crohn's disease. Vedolizumab SC will be given as an injection just under the skin. This type of injection is called a subcutaneous injection or SC for short. Another aim of the study is to collect information on whether the participant's condition remains under control or improves during and after treatment with Vedolizumab SC. Participants who previously took part in studies MLN0002SC-3027 or MLN0002SC-3031 will be invited to visit the study clinic. At this visit, the study doctor will check if each participant can take part in this study. For those who can take part, participants will receive a subcutaneous injection of vedolizumab SC either once a week or once every 2 weeks. How often each participant receives vedolizumab SC will depend on their results from the previous study and on how active their condition is. Participants might be able to self-inject vedolizumab SC after being trained by the study doctors. During this study, the dose of vedolizumab SC might be increased for participants whose condition worsens. Participants will continue treatment with vedolizumab SC until it is approved in their particular country, the participant decides to stop treatment, or the sponsor stops the study. If the sponsor stops the study before vedolizumab SC is approved in all countries, the sponsor will make sure all affected participants will have access to vedolizumab SC outside of the study. After their final dose of vedolizumab SC, participants will visit the clinic 18 weeks later for a final check-up. Then, the clinic will telephone the participants 6 months after their final dose of vedolizumab SC to check if they have any health problems.
This study is for young children with severe hemophilia A who have previously not been treated with BAX855 or other FVIII concentrates. The main aim of the study is to check for side effects from treatment with BAX855. This includes the buildup of antibodies against FVIII which may stop BAX855 from working properly. Another aim is to learn how well BAX855 controls bleeding. In this study, the children can receive BAX855 either as preventative treatment (prophylaxis), or as needed to treat bleeding (on-demand). In case a participant develops antibodies, treatment will be provided as part of the study.
The purpose of this study is to determine whether the gastric retentive Accordion Pill™ Carbidopa/Levodopa (AP-CD/LD) is more effective than the commercially available immediate release Carbidopa/Levodopa in reducing motor fluctuations such as "off time" in advanced Parkinson's Disease patients.
The rollover study will provide ceritinib to patients who are currently receiving treatment with ceritinib within a Novartis-sponsored study and in the opinion of the investigator, would benefit from continued treatment with ceritinib.
ASIT naïve patients sensitized to grass pollens will be recruited for the study. All of them will be instructed to treat bothersome in-season symptoms when they appear (on as needed, pro re nata basis) with rescue medication. They will be given 5 different options and will be informed about the effects of each of them in order to make their optimal choice for different symptoms and their combination: local decongestant (xylomethazoline, when congestion is leading), local antihistamine (azelastine, when itching, sneezing and rhinorhea a predominant), nasal corticosteroid (momethasone, when all nasal symptoms are pressing and no adequate relief is obtained form the other 2 local treatments), oral antihistamine (bilastine, when itching and sneezing persist despite the local treatments) and oral corticosteroid (prednisolone, when any or all symptoms become unbearable despite the other suggested treatments). Patients who are reluctant to use immunotherapy or who are too late to initiate it will be randomized to be treated with the listed medications on as needed basis, the nasally applied formulations will be followed by either HPMC to prolong and enhance their effect (Group HPMC) or placebo (lactose powder) (Group Placebo) to serve as control. Patients indicated and willing to carry out ASIT will be treated according to the standard protocol with grass allergens sublingually (Staloral #688) and will receive rescue medication (Group Immunotherapy).
