NCT ID: NCT06330909 Recruiting - Prostate Cancer Clinical Trials

Image-guided Focal Dose Escalation- Primary pc Treated With Primary External Beam Hypofract.Stereotactic rt

HypoF-SBRT
Start date: August 18, 2022
Phase: N/A
Study type: Interventional

Technical advances in radiotherapy (RT) treatment planning and delivery have substantially changed RT concepts for primary prostate cancer (PCa) by (i) enabling a reduction of treatment time and by (ii) enabling a safe delivery of high RT doses. Several studies proposed a dose-response relationship for patients with primary prostate cancer (PCa) and especially in patients with high-risk features a dose escalation should lead to improved tumor control. In parallel to the improvements in RT techniques, diagnostic imaging techniques like multiparametric magnetic resonance imaging (mpMRI) and positron-emission tomography (PET) evolved and enable an accurate depiction of the intraprostatic tumor mass for the first time. The HypoFocal-SBRT study combines ultra-hypofractionated RT / stereotactic body RT (reduction of treatment time) with a focal RT dose escalation on intraprostatic tumor sides by applying state of the art diagnostic imaging and most modern RT concepts. This novel concept will be compared with moderate hypofractionated RT (MHRT), one option for the curative primary treatment of PCa, which has been proven by several prospective trials and is recommended and carried out worldwide. We suspect an increase in relapse-free survival (RFS) and we will also assess quality of life in order to detect potential changes.

NCT ID: NCT06329362 Recruiting - Alveolar Bone Loss Clinical Trials

Minimally Invasive Ridge Splitting Versus the Conventional Open Flap Technique

Start date: July 31, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to compare implant stability, and crestal bone loss, when using minimal invasive ridge splitting versus convenient open flap technique.

NCT ID: NCT06323772 Recruiting - Clinical trials for Retinitis Pigmentosa

Natural History Study in Patients With PDE6A-, PDE6B- and RHO-linked Retinitis Pigmentosa

Start date: November 17, 2023
Phase:
Study type: Observational

The aim of the study is to apply a novel clinical investigation protocol in patients with Phosphodiesterase 6A (PDE6A), PDE6B and Rhodopsin (RHO)-based retinitis pigmentosa. This novel, multimodal clinical examination protocol describes and correlates structural, functional and metabolic aspects during natural disease development. Test-retest variability of new measurements as well as correlations of the structural, functional, and metabolic changes will be defined to be able to define well-suited readouts for safety and efficacy of future treatment developments before they reach the clinical phase.

NCT ID: NCT06321562 Recruiting - Clinical trials for Primary Open-angle Glaucoma

Safety and Tolerability of a Timolol Releasing Intraocular Implant in Subjects With Primary Open-angle Glaucoma

Start date: March 1, 2023
Phase: Phase 1
Study type: Interventional

The purpose of this study is to test a new method to deliver an approved medicine called Timolol in the eye of participants with glaucoma and pseudophakia. The main questions it aims to answer are how safe the investigational drug is and how the body tolerates it. The study will also check: - how safely the implant is placed in and removed from the eye and how the body responds to the procedure, - how safe different doses of timolol are and how the body handles taking it, - the amount of Timolol released in the bloodstream, - if there is any positive effect on the pressure inside the eye.

NCT ID: NCT06320223 Recruiting - Prostate Cancer Clinical Trials

PROMISE PET Registry on PSMA-PET and Outcome in Prostate Cancer

NCT ID: NCT06318052 Recruiting - Clinical trials for Vaginal Atrophy Patients With GSM

The Effect Of Fractional CO2 Laser Therapy On Cancer Survivors With Genitourinary Syndrome Of Menopause (GSM)

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

Improvement in cancer therapies has led to an increase in the number of women surviving chemotherapy (and other treatments) and overcoming cancer. This patient population presents specific clinical needs as chemotherapy (and other cancer treatments) treatment side effects can lead to early appearance of menopause symptoms and conventional hormonal treatments are contraindicated for these patients. The use of CO2 laser treatment has been shown to provide relief of Genitourinary Syndrome Of Menopause (GSM) symptoms in women and might provide a significant improvement in the quality of life for cancer survivors. The current study is designed to demonstrate the safety and efficacy of CO2 laser for treatment of GSM symptoms in cancer survivors suffering from GSM symptoms, with limited access to hormonal treatment.

NCT ID: NCT06317909 Recruiting - Clinical trials for Mild Allergic Asthma

Development of a Novel Non-invasive Inflammometry Following Allergen Challenge in Patients With Mild Allergic Asthma

Start date: June 1, 2024
Phase: N/A
Study type: Interventional

The goal of this exploratory method-development study is to to establish and evaluate novel non-invasive methods to monitor airway inflammation induced by allergen challenge (both by instillation during bronchoscopy and by inhalation) in patients with mild allergic asthma. The investigator wants to further profile and develop the allergen challenge model by investigating the utility of various non-invasive monitoring methods. The hypothesis of the project is that local inflammatory changes in the lung induced by allergen can be captured by gas-enhanced magnetic resonance imaging (MRI) and analysis of exhaled breath. The validation of cellular outcome measures and non-invasive inflammometry can be used in future clinical trials for proof of concept of novel anti-inflammatory medications. Participants will undergo - methacholine challenge - 2 inhaled allergen challenges - 2 MRI with hyperpolarized xenon and gadolinium based contrast agent - 2 bronchoscopies with bronchoalveolar lavage (BAL) - segmental allergen challenge during the first bronchoscopy - spirometry - skin prick test and skin prick dilution tests - measurement of particles in exhaled air - nasal filter - nasal lavage - sputum induction - peak flow meter tests - exhaled NO (nictric oxide) - blood sampling (in total approx. 190 ml)
