There are about 21071 clinical studies being (or have been) conducted in Spain. 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.
The underlying hypothesis of the synergistic activity of octreotide and everolimus is based on the combination of a) a direct action of everolimus over mTOR (mammalian target of rapamycin), and b) the inhibitory effect of octreotide on the IGF-I (insulin like growth factor 1) system preventing the activation of the mTOR system by this factor. Both types of inhibition would completely cancel this signal transduction pathway, which is so important in neuroendocrine tumours. Furthermore, the biological study proposed in this protocol will allow for better establishing the relationship between the activation of the IGFR-PI3K-mTOR signal transduction pathway (i.e., the mTOR pathway stimulated by IGFR) and treatment response; this information is relevant since the IGFR-PI3K-mTOR activation status could be a response prediction factor. This study will provide significant additional information about the efficacy of the combination treatment of everolimus with octreotide LAR® in non-functioning GI NET.
Allergen extracts are complex mixtures of proteins and contain varying amounts of allergenic and non-allergenic components. Many factors such as the biovariability, differences in extraction process and subsequent handling of allergens can affect the final composition, potency, and stability of allergen preparations. Genetic diversity of affected people adds another level of complexity. In order to control variability and to achieve consistency and reproducibility for optimal safety and sensitivity/specificity, it is essential to standardize the amount of allergen used in prick tests. Therefore, the system for biological standardization mainly used in Europe still is the biological calibration of in-House Reference Preparations (IHRP). The method has been adopted by the Nordic Council on Medicines as the Nordic Biological Unit, Histamine Equivalent Potency (HEP) or Skin Prick Test (SPT) value. The aim of this procedure is to estimate the biological activity of allergen extracts. The activity of an allergen extract is defined as 1 SPT per ml, when the extract provokes a specific skin reaction with a wheal of the same size as a wheal provoked by reference histamine at a concentration of 10 mg/ml, when both solutions are administrated using the same technique (prick testing) on at least 20 individuals who are sensitized to the allergen concerned. The present study aims to standardize the allergen extracts of Dactylis glomerata, Lolium perenne, Secale cereale y Olea europaea by using this method.
Based on EMA (European Medicines Agency) new guidelines on the clinical development of products for immunotherapy for the treatment of allergic diseases the aim of this study is to establish a dose-response relationship for clinical efficacy of Phleum pratense pollen extract subcutaneous vaccine.
Primary Objective: To evaluate the safety and potential efficacy of eculizumab to prevent AMR in sensitized recipients of deceased donor kidney transplants.
This trial is conducted in Asia, Europe and Oceania. The aim of this trial is to evaluate the safety and preliminary efficacy of activated recombinant human factor VII (NovoSeven®) in preventing early haematoma growth in acute Intracerebral Haemorrhage (ICH).
This multicenter, two-cohort, non-randomized, open-label study will evaluate the safety and tolerability of assisted and self-administered SC Herceptin as adjuvant therapy in participants with early HER2-positive breast cancer following tumor excision. Participants will receive Herceptin 600 milligrams (mg) SC every 3 weeks for 18 cycles, either by an assisted administration using a conventional syringe and needle/vial formulation (Cohort A) or with assisted and self-administration using a single-use injection device (SID) in selected participants (Cohort B).
Evaluation of the Efficacy and Safety of Oral Azacitidine plus Best Supportive care versus Placebo and Best Supportive care in subjects with red blood cell (RBC) transfusion-dependent anemia and thrombocytopenia due to International Prognostic Scoring System (IPSS) lower risk myelodysplastic syndromes (MDS).
The study consists on determining whether melatonin decreases oxidative stress in Barrett's esophageal mucosa after 6 months of treatment. In order to achieve the clinical trial, the patients will be randomized to two possible arms: omeprazole alone or omeprazole plus melatonin. The patients will be followed around four visits during six months. GERD is one of the most prevalent pathologies in the digestive tract. Barrett's esophagus, a complication of chronic GERD, has attracted the attention of researchers due to its condition of pre-neoplastic lesion. At present, treatment of Barrett's patients is limited to acid inhibition with PPIs. Although there are several studies which indicate that treatment with PPIs could decrease the incidence of high grade dysplasia and EAC, treatment with PPIs does not eliminate the risk of EAC in these patients. Therefore, it is necessary to find chemo-preventive agents that stop neoplastic progression of Barrett's esophagus. Among them, antioxidants have become the most promising agent. This pilot study will determine the efficacy of melatonin in the chemoprevention of EAC. So, the main objective of this study is to determine whether melatonin decreases oxidative stress in Barrett's esophageal mucosa after 6 months of treatment. To evaluate whether melatonin modifies other mechanisms associated to neoplastic progression in BE patients: proliferation and apoptotic index and molecular markers of progression: 17pLOH, 9pLOH, p16 methylation and DNA ploidy (tetraploidy and/or aneuploidy).
Multicenter, open label, non-randomized phase 2 trial to evaluate the efficacy and safety of nab-paclitaxel in the neoadjuvant treatment of ER positive human epidermal growth factor receptor 2 (HER2) negative patients amenable to receive neoadjuvant chemotherapy.
This two-cohort, open-label, multicenter, phase II study will assess the safety and efficacy of pertuzumab given in combination with Herceptin (trastuzumab) and vinorelbine in first line in patients with metastatic or locally advanced HER2-positive breast cancer. Patients will receive pertuzumab 840 mg and Herceptin 8 mg/kg administered sequentially as separate iv infusions on Days 1 and 2, respectively, of Cycle 1. From Cycle 2 onwards, patients will receive pertuzumab 420 mg and Herceptin 6 mg/kg, administered either sequentially as separate iv infusions on Day 1 and Day 1 or 2, respectively (Cohort 1) or together in one infusion bag on Day 1 (Cohort 2) every 3 weeks. Vinorelbine will be administered at 25 mg/m2 iv on Days 2 and 9 of Cycle 1, and at 30-35 mg/m2 on Days 1 and 8 (or Days 2 and 9) of each following 3-week cycle. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs, or withdrawal of consent or death.
