Active clinical trials for "Radiation Injuries"

The principle objective of this research is to more precisely determine the degree of benefit that hyperbaric oxygen therapy affords in the treatment of late radiation tissue injury. The study has eight* components. Seven involve the evaluation of established radionecrosis at varying anatomic sites (mandible, larynx, skin, bladder, rectum, colon, and gyn). The eighth will investigate the potential of hyperbaric oxygen (HBO) therapy to prophylax against late radiation tissue injury. *(One of the arms, HORTIS IV - Proctitis has been closed to further patient recruitment. This decision was based on an interim statistical analysis which generated sufficient evidence to support closing down this arm of HORTIS.)

The purpose of this project is to quantify normal and abnormal skin blood flow regionally in different areas of the body(face, extremities, over burns and wounds) at baseline and over time in response to treatment or environmental changes, such as temperature, light and pressure.

This trial is designed to evaluate the safety, pharmacokinetics, and pharmacodynamics of HemaMax in healthy male and female volunteers.

There is a wide variability of options for treatment of chronic radiation proctitis. However, studies are still limited, usually case reports from a single center and few are comparative studies between methods. Therefore, the choice of treatment is determined by availability and local expertise for each method. The variability of treatment options range from anti-inflammatory medical treatment, sucralfate, short chain fatty acids, antioxidants and hyperbaric oxygen to such endoscopic and surgical treatments. Surgery is usually the last therapeutic option due to the high morbidity and mortalityassociated. Various endoscopic treatment modalities have been reported. Formalin topic is effective in up to 48% of patients with chronic radiation proctitis. The endoscopic treatment with argon plasma (APC) is low cost, easy to apply and transportation, safe and effective in the treatment of rectal bleeding in patients with chronic radiation proctitis. Currently, the APC is the preferred endoscopic modality. Most studies on the use of APC in radiation proctitis showed benefit. The APC controls the mild to moderate rectal bleeding in 80% to 90% of cases and improves symptoms of urgency, diarrhea and tenesmus in 60% to 75% of cases.

Patients who undergo total body irradiation (TBI) for stem cell transplantation have prolonged periods of low counts of specific blood cells called platelets. These low platelets counts can cause bleeding and infection. Thus far, no drug is available for use to speed the recovery of platelets, and therefore transfusions are often necessary. The purpose of this study is to test the safety of a drug called eltrombopag in patients who have received TBI. The investigators want to find out what effects, good or bad, it has on people with low platelet counts due to treatment with TBI. The investigators will also be testing how well eltrombopag may work at different doses and determine if this drug speeds up the recovery of the platelets.

This study aims to characterise the impact of radiotherapy on physical symptoms and quality of life in childhood and young adult cancer survivors. This is in line with current NHS strategic priorities and an unmet clinical need to optimise aftercare in this patient group. In order to provide effective treatment strategies, the scale and impact of symptom burden requires better characterisation. A significant proportion of adult patients suffer with gastrointestinal and urinary symptoms and sexual dysfunction following radiotherapy treatment. However there is a lack of data in the paediatric and young adult population. We will study patients who underwent abdomino-pelvic radiotherapy, who completed treatment between 2000 and 2021 and were under the age of 24 years at the time of treatment. Patients will be recruited from The Royal Marsden Hospital, Great Ormond St Hospital and University College Hospital. Once these patients are identified we propose to prospectively assess severity of their ongoing symptoms using an electronic questionnaire, including relevant extracts from existing validated questionnaires. Treatment and patient related factors will be extracted from patient hospital records. A further qualitative arm of the study will be completed on a sub-set of 10 patients. We will identify appropriate patients that are willing to participate in qualitative research at the time of consenting. One-to-one interviews will be conducted to gain a better insight into their symptom burden, quality of life, patient perceptions of current services and view of currently unmet needs. This study will provide novel data on the frequency and severity of gastrointestinal and bladder related radiotherapy toxicity in young adult cancer survivors and assess impact on sexual function and quality of life. We would then propose to use this data to focus on service improvements within the regional paediatric and TYA cancer aftercare service driven by patient experience and clinical need.

This trial is designed to evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic of KMRC011 injection in healthy adult volunteers.

This trial is designed to evaluate the safety and pharmacokinetics of BIO 300 capsules when administered orally to healthy male and female volunteers. BIO 300 is expected to be safe for use starting at 500 mg.

The purpose of this study is to determine whether HemaMax is safe and well tolerated to support efficacy under FDA's Animal Rule to reduce the morbidity and mortality associated with the hematopoietic syndrome of acute radiation syndrome.

Aim: To compare the efficacy, safety and number of sessions of bipolar eletrocoagulation (BEC) and argon plasma coagulation (APC) in the management of the bleeding telangiectasias from chronic radiation coloproctopathy (CRCP). Methods: Thirty patients with active bleeding from telangiectasias were enrolled in two groups (15 BEC and 15 APC) and classified according of Saunders score. BEC settings were 50 W and APC settings were 40 W and 1.0 l/min. Colonoscopy was the first exam to rule out synchronous lesions and follow-up was performed with sigmoidoscopies. Clinical cure was defined as cessation of bleeding and endoscopic cure was determined by absence of telangiectasias. Failure was defined whenever more than 7 sessions or other therapy was necessary.
