Bevacizumab Injection for Recurrent Pterygium
Recurrent PterygiumBlockade of vascular endothelial growth factor (VEGF) with bevacizumab has been used to treat abnormal vascular conditions of the anterior segment of the eye. In pterygium, anti-VEGF agents have been recently proposed as primary treatments, such as perioperative adjuvants, as well as treatments for pterygia recurrences after surgery. The aim of the present study was to prospectively evaluate the effect of three subconjunctival bevacizumab injections in patients with an early pterygium recurrence. Materials and Methods: The current study was a non-randomized single central trial. The method of ensuring allocation concealment was sequentially numbered. Patients with an early pterygium recurrence were selected and invited to participate in the study. Recurrence was defined as the presence of corneal vessels with concomitant conjunctival hyperemia within the first trimester after primary pterygium removal, and only patients with primary pterygium recurrence were included. Patient related factors such as pregnancy, women seeking to become pregnant, and lactating women were excluded from the study. All patients received three subconjunctival bevacizumab (2.5 mg/0.05 ml) injections (basal, 2 and 4 weeks) in the recurrence area of the pterygium, and were photographed at the third, sixth and twelfth months after the last bevacizumab injection. Photographic analyses were performed taking into account two pterygium areas: the first measure included only the vessel area in the corneal surface, while the second measure included, both, conjunctival and corneal vessel area (corneal-conjunctival area of hyperemia). Neovascularization area of each pterygium was determined using digital slit lam pictures, which were analyzed using Photoshop CS4, in order to get pixels measurements of the lesion.

Biospecimen Collection in Assessing the Effect of Trametinib With or Without Uprosertib on Biomarkers...
Recurrent Endometrial CarcinomaThis trial assesses blood and tumor samples for the effect of trametinib with or without uprosertib on biomarkers in patients enrolled on trial GOG02290 with endometrial cancer that is persistent or has come back. Biomarkers found in the blood and tissue may be related to the reaction or response to the study drugs.
Preventing Relapse Following Involuntary Smoking Abstinence
SmokingSmoking CessationThe prevalence of tobacco use in the military is too high. This study is designed to take advantage of the 8.5 weeks of forced tobacco cessation during Basic Military Training and develop effective interventions to prevent tobacco relapse. Hypotheses or Research Questions: Are there differences in the rate of relapse between three groups participating in a tobacco abstinence maintenance intervention? Do the tobacco abstinence maintenance interventions delay relapse?

Crohn's DiseaseA double-blind, multicentre, stratified by centre, randomised, parallel study with two groups of adult patients operated on for Crohn's disease, to determine if oral ingestion of probiotics could prevent the appearance of Crohn's disease recurrent endoscopic ileo-colonic lesions 12 months after surgery. Patients will consume 900 mg/day of active product (N=56) or control product (N=56) during one year.
Avastin / Irinotecan in Patients With Recurrent or Progressive Malignant Glioma
Recurrent Malignant GliomaMalignant glioma are the most common and aggressive primary brain tumors in adults. Despite advances in multimodal treatment including surgery, radiation and chemotherapy, most patients have a dismal prognosis of 9-15 months (Stupp et al., NEJM 2005). A major reason for the aggressiveness of malignant glioma is a pronounced tumor neovascularization, mainly driven by the vascular endothelial growth factor (VEGF) and its receptors. The therapeutic monoclonal antibody Bevacizumab (Avastin®) inhibits the VEGF pathway by binding the VEGF ligand. In Magnetic Resonance Imaging (MRI) this treatment reduces contrast enhancement by restoring both, the blood-brain-barrier and the destabilized vessel integrity. Furthermore, it raises the sensitivity of co-administered chemotherapeutics such as Irinotecan. In conclusion, anti-angiogenic therapy leads to the problem that the routinely used MRI techniques cannot distinguish anti-vascular effects from true anti-tumor effects. The study hypothesis of the clinical trial part is that in 35% of malignant glioma patients Avastin / Irinotecan chemotherapy results in objective tumor responses assessed by standard / functional MRI and FET- /FLT-PET neuroimaging. The study hypothesis for the translational study part is that the expression of the molecular targets of Avastin and Irinotecan in malignant glioma tissue ( = tumor and vascular cells) are predictive for Avastin / Irinotecan therapy induced treatment response measured by functional MRI and FET- / FLT-PET imaging.
