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.
This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000mg iv infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.
The primary objective of the study is to compare the effect of 90-day treatment with ticagrelor (180 mg [two 90 mg tablets] loading dose on Day 1 followed by 90 mg twice daily maintenance dose for the remainder of the study) vs acetylsalicylic acid (ASA)-aspirin (300 mg [three 100 mg tablets] loading dose on Day 1 followed by 100 mg once daily maintenance dose for the remainder of the study) for the prevention of major vascular events (composite of stroke, myocardial infarction [MI], and death) in patients with acute ischaemic stroke or transient ischaemic attack (TIA).
The study hypothesis under test is that administration of the CCR2/5 antagonist has the potential to be as effective as the current treatment options for subjects with diabetic macular edema. The current treatment option for these subjects is an injection directly into the eye, while this CCR2/5 antagonist would be an oral drug which has the potential to be just as effective. This CCR2/5 antagonist also has a broader anti-inflammatory potential and might be able to provide an alternative mechanism to treat Diabetic Macular Edema.
The purpose of this study is to evaluate the rate of decline in quantitative viral load measured in hospitalized patients with Influenza A infection
The purpose of this study is to compare the effect of ticagrelor versus placebo in patients with Type 2 Diabetes Mellitus.
The purpose of this study is to provide 24 - 52 week efficacy, safety and tolerability data, and up to 3-year efficacy, safety and tolerability data in subjects with active Psoriatic Arthritis despite current or previous nonsteroidal anti-inflammatory drug (NSAID), disease-modifying antirheumatic drug (DMARD) therapy and/or previous anti-tumor necrosis factor alpha (TNFα) therapy.
M5181 - a novel vitamin D3 analogue - is currently under development for the treatment of plaque psoriasis and is being developed as a topical ointment formulation (M518101) Clinical and non-clinical studies indicate that M5181 is an effective treatment for plaque psoriasis. Based on the results of previous phase II trials the phase III trial has been designed to evaluate efficacy and safety of an 8-week treatment period with 50 μg/g M518101 in a larger population of patients with stable plaque psoriasis.
The purpose of this study is to evaluate the accuracy of a subset of the length-109 probe set panel (a genetic test) in predicting response to golimumab treatment in participants with moderately to severely active ulcerative colitis (UC).
The primary objectives of the study are: - To evaluate the safety and tolerability of three dose levels of MT-1303 in subjects with moderate to severe chronic plaque psoriasis. - To evaluate the efficacy of three doses levels of MT-1303 in subjects with moderate to severe chronic plaque psoriasis compared to placebo after 16 weeks of treatment on Psoriasis Area and Severity Index (PASI).
Allergic rhinitis is treated with a variety of systemic and locally applied drugs. The effectiveness of the intranasally applied formulations is diminished by the cleaning mechanisms of the nose, rhinorrhea in particular. Slowing down of the clearance of the nasal mucosa and prolonging the contact time of locally applied drugs with the nasal mucosa would improve their efficacy. One method is creating dosage forms containing mucoadhesive polymers. We have demonstrated that a mucoadhesive solution containing HPMC enhances the clinical efficacy of oxymetazoline. However, the industrial development of fixed combinations of pharmaceutical compound and mucoadhesive carrier requires substantial investments, escalating manifold if different pharmaceutical compounds have to be rendered mucoadhesive. NoAl is a cellulose derivative powder, which forms a gel layer on contact with the mucosal surface of the nose blocking the contact of the pollen grains with the nasal mucosa in seasonal allergic rhinitis. However, there is another potential benefit of applying NoAl (HPMC) along with other commercially available drugs for local treatment of rhinitis, as the formation of a gel layer can substantially delay their clearance from the nose and thus increase their effectiveness. This hypothesis needs to be substantiated clinically.
