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 is a randomized, open-label, multi-center, global, Phase III study to determine the efficacy and safety of durvalumab + tremelimumab combination therapy versus platinum-based SoC chemotherapy in the first-line treatment of patients with epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) wild-type advanced or metastatic NSCLC.
The purpose of this study is to evaluate the long-term safety and efficacy of RPC1063 in participants with moderately to severely active ulcerative colitis. Only those participants who have previously participated in a trial of RPC1063, being either RPC01-3101 or completed at least 1 year of the open-label period of RPC01-202 will be eligible.
The main objective of this study is to evaluate the efficacy of SRP-4045 (casimersen) and SRP-4053 (golodirsen) compared to placebo in participants with DMD with out-of-frame deletion mutations amenable to skipping exon 45 and exon 53, respectively.
The purpose of this study was to evaluate whether copanlisib in combination with rituximab is superior to placebo in combination with rituximab in prolonging progression free survival (PFS) in patients with relapsed iNHL who have received one or more lines of treatment, including rituximab and who either had a treatment-free interval of ≥ 12 months after completion of the last rituximab-containing treatment, or who are unwilling to receive chemotherapy/for whom chemotherapy is contraindicated on reason of age, comorbidities, and/or residual toxicity.
The purpose of Phase 1b of this study is to: - Asses the safety, tolerability and activity of carfilzomib, alone and in combination with induction chemotherapy, in children with relapsed or refractory acute lymphoblastic leukemia (ALL). - Determine the maximum tolerated dose (MTD) and to recommend a phase 2 dose of carfilzomib in combination with induction chemotherapy. The purpose of Phase 2 of this study is to compare the rate of complete remission (CR) of carfilzomib in combination with vincristine, dexamethasone, PEG asparaginase, daunorubicin (VXLD) at the end of induction therapy to an appropriate external control.
To assess the efficacy and safety of AZD9291 versus a standard of care epidermal growth factor receptor tyrosine kinase inhibitor in patients with locally advanced or Metastatic Non Small Cell Lung Cancer
The main objectives of Part 1 are as follows: To evaluate the safety, tolerability, and efficacy of BG00012 in pediatric subjects with RRMS, as compared with a disease-modifying treatment and to assess health outcomes and evolution of disability. The primary objective of Part 2 is to evaluate the long-term safety of BG00012 in subjects who completed Week 96 in Part 1 of Study 109MS306. The secondary objective of Part 2 is to describe the long-term MS outcomes of BG00012 in subjects who completed Week 96 in Part 1 of Study 109MS306.
The purpose of this study is to find out whether it is better to receive a new drug, MEDI4736, or better to receive no further treatment after surgery (and possibly chemotherapy) for lung cancer.
This open-label, multicenter, randomized Phase III study is designed to compare the efficacy and safety of a combined regimen of obinutuzumab and venetoclax versus obinutuzumab + chlorambucil in participants with chronic lymphocytic leukemia (CLL) and coexisting medical conditions. The time on study treatment was approximately one year and the follow-up period will be up to 9 years.
Primary Objective: To assess the effect of teriflunomide in comparison to placebo on disease activity measured by time to first clinical relapse after randomization in children and adolescents 10 to 17 years of age with relapsing forms of multiple sclerosis (MS). Secondary Objective: - To assess the effect of teriflunomide in comparison to placebo on disease activity/progression measured by brain magnetic resonance imaging (MRI) and on cognitive function. - To evaluate the safety and tolerability of teriflunomide in comparison to placebo. - To evaluate the pharmacokinetics (PK) of teriflunomide.
