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 was an adaptive design phase 2 study to establish safety and efficacy; and to characterize the dose-response of LOU064 in subjects with moderate to severe Sjögren's syndrome. LOU064 is an oral Bruton's tyrosine kinase (BTK) inhibitor.
This study [contRAst 2 (201791: NCT03970837)] is a phase 3, randomized, multicenter, double blind study to assess the safety and efficacy of GSK3196165 in combination with csDMARD(s), for the treatment of adult participants with moderate to severe active rheumatoid arthritis (RA) who have had an inadequate response to csDMARD(s) or bDMARD(s). The study will consist of a screening phase of up to 6 weeks followed by a 52 week treatment phase in which participants will be randomized in a ratio of 6:6:3:1:1:1 to receive GSK3196165 150 milligrams (mg) subcutaneous (SC) weekly, GSK3196165 90 mg SC weekly, tofacitinib capsules (cap) 5 mg twice a day or placebo (three arms, each placebo arm will have 12 weeks placebo followed by 40 weeks active treatment) respectively, all in combination with csDMARD(s). Participants who, in investigator's judgement will benefit from extended treatment with GSK3196165 may be included in the long-term extension study [contRAst X (209564: NCT04333147)]. For those participants who do not continue into the long term-extension study, there will be an 8 week safety follow-up visit following the treatment phase.
A study to evaluate the long-term safety and tolerability of flexible doses of Lu AF11167 in patients with schizophrenia during the 24-week treatment period
A 3-Year Multi-Center, Long-Term Safety (LTS) Study to Evaluate the Safety and Tolerability of TD-1473 in Subjects with Ulcerative Colitis who have participated in the Maintenance Study of Protocol 0157
This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786, as compared with placebo, for the treatment of negative symptoms of schizophrenia.
This is a Phase 2, multicenter, randomized, double-blind, parallel group, placebo-controlled study to investigate the safety, tolerability, efficacy and dose-response of GSK2831781 in participants with moderate to severe active ulcerative colitis. The study consists of a 5-week screening window, 10-week Induction Phase, 30-week double-blind Extended Treatment Phase (ETP) with 42-week Follow-Up Phase. Non-Responders identified following the Week 10 assessment will be allocated to open label treatment, consisting of Induction (Weeks 12 to 22), an Open label ETP (Weeks 22 to 42) and a follow-Up to Week 54.
Study CYC-202 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of ST-0529 in subjects with moderately to severely active UC, defined as a score of 5 to 9 on the 3-Component Adapted Mayo Score (comprised of rectal bleeding, stool frequency and endoscopy sub-scores; score range 0-9).
The primary objective of this study is to assess the efficacy of Debio 1347 in terms of objective response rate (ORR) in participants with solid tumors harboring fibroblast growth factor receptor (FGFR)1-3 gene fusion/rearrangement.
A Phase 3, 22-week, Multi-center, Randomized Withdrawal Study of ampreloxetine in Treating Symptomatic Neurogenic Orthostatic Hypotension in Subjects with Primary Autonomic Failure
