There are about 4372 clinical studies being (or have been) conducted in Greece. 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, double blind, controlled, parallel group, multicenter study to evaluate efficacy, safety and pharmacokinetics of a higher dose of ocrelizumab per intravenous (IV) infusion every 24 weeks in participants with PPMS, in comparison to the approved 600 mg dose of ocrelizumab.
This Phase III, randomized, double-blind, placebo-controlled, multicenter study will evaluate the efficacy and safety of giredestrant combined with palbociclib compared with letrozole combined with palbociclib in patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor-2 (HER2)-negative locally advanced (recurrent or progressed) or metastatic breast cancer.
A study to evaluate the efficacy and safety of fenebrutinib on disability progression in adult participants with Primary Progressive Multiple Sclerosis (PPMS). All eligible participants will be randomized 1:1 to either daily oral fenebrutinib (and placebo) or intravenous (IV) ocrelizumab (and placebo) in a blinded fashion through an interactive voice or web-based response system (IxRS). Approximately 946 participants will be enrolled and will be recruited globally. Participants who discontinue study medication early or discontinue from the study will not be replaced. The Open-Label Extension (OLE) phase is contingent on a positive benefit-risk result in the Primary Analysis of the study.
This is a randomized, double blind, controlled, parallel group, multicenter study to evaluate efficacy, safety and pharmacokinetics of a higher dose of ocrelizumab per intravenous (IV) infusion every 24 weeks in participants with RMS, in comparison to the approved 600 mg dose of ocrelizumab.
160 subjects with autoimmune pulmonary alveolar proteinosis (aPAP) will be randomized to receive once daily treatment with inhaled molgramostim or placebo for 48 weeks. Subjects completing the 48 week placebo-controlled period will receive open-label treatment with once daily inhaled molgramostim for 96 weeks.
The purpose of this study is to evaluate the efficacy and safety of tiragolumab plus atezolizumab compared with placebo in participants with unresectable esophageal squamous cell carcinoma (or those who are unable or unwilling to undergo surgery) and whose cancers have not progressed following definitive concurrent chemoradiotherapy (dCRT). Participants will be randomized in a 1:1:1 ratio to receive either tiragolumab plus atezolizumab (Arm A), tiragolumab matching placebo plus atezolizumab (Arm B), or double placebo (Arm C).
This study will evaluate the safety and tolerability of iscalimab at two dose levels in patients with Sjögren's Syndrome, who participated in the TWINSS core study, CCFZ533B2201(NCT03905525). Additionally, this Extension study will further explore the pharmacokinetics (PK) and efficacy of iscalimab at two dose level.
The primary objective of this study is to assess overall survival (OS) with sacituzumab govitecan-hziy in comparison with treatment of physician's choice (TPC) in participants with metastatic or locally advanced unresectable urothelial cancer (UC).
Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. This study will evaluate how well risankizumab works compared to ustekinumab. This study will assess change in Crohn's Disease Activity Index (CDAI). Risankizumab is an investigational drug being developed for the treatment of Crohn's Disease (CD). Ustekinumab is an approved drug for the treatment of moderate and severe CD. Participants are randomly assigned to one of the three treatment groups. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to ustekinumab. Around 508 adult participants with moderate to severe CD will be enrolled in approximately 307 sites worldwide. In Part 1, participants assigned to risankizumab will receive intravenous (IV) doses of risankizumab at Week 0, 4,8 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. Participants assigned to ustekinumab will receive intravenous (IV) dose of ustekinumab at Week 0 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. In Part 2, participants who received risankizumab in Part 1 and completed the Week 48 visit will continue to receive SC risankizumab for up to an additional 220 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The purpose of this study is to evaluate the efficacy and safety of atezolizumab in combination with tiragolumab compared with durvalumab in participants with locally advanced, unresectable Stage III non-small cell lung cancer (NSCLC) who have received at least two cycles of concurrent platinum-based chemoradiotherapy (CRT) and have not had radiographic disease progression.
