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.
To compare and evaluate the efficacy and safety of Liporaxel® solution (oral paclitaxel) and Taxol® (IV paclitaxel) on recurrent or metastatic breast cancer.
Octreotide capsule is a novel, orally-administered formulation of the commercially-available injectable drug octreotide. In a recent phase 3 trial, oral octreotide capsules demonstrated maintenance of biochemical response up to 13 months in the majority of patients with acromegaly previously managed with somatostatin analog injections (reference below).
This is an international, multicentre, prospective, non-interventional, observational Registry of patients with X-Linked hypophosphatemia (XLH). The main objective of this XLH Registry is to collect data to characterise the treatment, progression and long-term outcomes of XLH in both adult and paediatric settings.
This is a randomized, open-label, multi-center, global, Phase III study to determine the efficacy and safety of durvalumab + tremelimumab combination therapy + Standard of care (SoC) chemotherapy or durvalumab monotherapy + SoC chemotherapy versus SoC chemotherapy alone as first line treatment in patients with metastatic non small-cell lung cancer (NSCLC) with tumors that lack activating epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusions.
This is an open-label, multicenter, non-randomized extension and long-term observational study. Participants receiving atezolizumab monotherapy or atezolizumab combined with other agent(s) or comparator agent(s) in a Genentech or Roche-sponsored study (the parent study) and who continue to receive study treatment at the time of the parent-study closure and do not have access to the study treatment locally are eligible for continued treatment in the extension study. Dosing regimen for a given participant and indication will be the same or equivalent to the respective parent study protocol. Study treatment in the extension study can continue until disease progression or beyond if the patient continues to derive clinical benefit as judged by the investigator and if allowed by the parent study or local prescribing information until death; withdrawal of study consent; unacceptable toxicity; pregnancy; patient non-compliance; or study termination by the Sponsor, whichever occurs first.
To evaluate the long-term safety and tolerability of pimavanserin after 52 weeks of adjunctive treatment in subjects with schizophrenia
This Phase 3, 2-arm, randomized, active comparator-controlled, open-label, multicenter study will compare the efficacy and health-related quality of life (HR-QoL) and assess the safety of selinexor plus bortezomib (Velcade) plus low-dose dexamethasone (SVd) versus bortezomib plus low-dose dexamethasone (Vd) in adult patients with RRMM who have received 1 to 3 prior anti-multiple myeloma (MM) regimens. Crossover from the Vd Arm to a treatment that includes selinexor (i.e., SVdX or SdX) will be allowed at the point of IRC-confirmed objective disease progression per the IMWG criteria for patients in the Vd Arm.
The purpose of this pivotal study was to compare the efficacy of asciminib (ABL001) with that of bosutinib in the treatment of patients with CML-CP having previously been treated with a minimum of two prior ATP-binding site TKIs. Patients intolerant to the most recent TKI therapy must have had BCR-ABL1 ratio > 0.1% IS at screening and patients failing their most recent TKI therapy must have met the definition of treatment failure as per the 2013 European LeukemiaNet (ELN) recommendations. Patients with documented treatment failure as per 2013 ELN recommendations while on bosutinib treatment had the option to switch to asciminib treatment within 96 weeks after the last patient has been randomized on study.
The study consists of 4 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in participants with moderately to severely active Crohn's disease (CD) who responded to intravenous risankizumab induction treatment in Study M16-006 or Study M15-991; - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in participants who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in participants who completed Sub-study 1, Sub-study 2, another AbbVie risankizumab Crohn's disease study, or participants who responded to induction treatment in Study M16-006 or Study M15-991 with no final endoscopy due to the Covid-19 pandemic. Additional objectives are to further investigate long-term efficacy and tolerability of risankizumab; - Sub-study 4 (Open-label On Body Injector (OBI) administration and long-term extension study) to evaluate patient-reported outcomes, efficacy, safety, tolerability, and pharmacokinetics of risankizumab administered via OBI in participants who are receiving maintenance treatment with risankizumab. - OL CTE to ensure uninterrupted care in accordance with local regulations until risankizumab is commercially available for participants who completed Sub-study 3, Sub-study 4.
This study includes two periods. The main objective of Period 1 is to compare the efficacy of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo and versus adalimumab (Humira®) in participants with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response to non-biologic DMARDs (DMARD-IR). Period 1 is also designed to compare the efficacy of upadacitinib 15 mg and 30 mg QD versus placebo for the prevention of structural progression. The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg and 30 mg QD in participants who have completed Period 1.
