An interventional study of Low dose Radiotherapy in Covid19, sponsored by Lancashire Teaching Hospitals NHS Foundation Trust. Completed at 1 site in United Kingdom. Open to participants aged 50 Years and older. Per ClinicalTrials.gov, last updated 2022-11-10.
Sponsored by Lancashire Teaching Hospitals NHS Foundation Trust · Not applicable, Interventional, and Health services research
The purpose of this study is to document the feasibility and tolerability of low dose thoracic radiotherapy in patients with WHO level 5 COVID 19 infections.
Subjects will be identified following admission to hospital who test positive for COVID-19 infection. They will then be informed and consented, and eligibility confirmed and registered to study. Following this the first, sentinel patient, will be treated with 0.5Gy dose radiotherapy to cover the lungs, with heterogeneity correction. A further 0.5Gy dose can be repeated within 96 hours. There shall then be a 7 day gap prior to recruiting patient 2. The remaining patients will be recruited, treated and observed in cohorts of 3.
The patients shall then be followed up at 48 hours post Radiotherapy, 7 days post radiotherapy and 29 days post radiotherapy. With assessment of Physiological parameters, survival status, laboratory testing and imaging performed on follow up at 7 and 29 days.
7,990 studies on the registry are indexed under COVID-19; 466 are open to participants now.
This study's enrollment of 2 is below the median of 102 across 4,364 interventional studies indexed under COVID-19.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Low Dose Radiotherapy
Radiation: Low dose Radiotherapy
External Beam irradiation, single fraction of 0.5Gy, to be delivered within 48 hours of enrolment to study. With field to cover as close to lung edges as AP/PA technique allows. A further 0.5GY to the thorax given up to 96 hours apart from first fraction is permitted, if a patient had either (a) responded to the first dose but then deteriorated, however remaining better than baseline level or (b) stabilized after first dose but not fully improved.
Feasibility of Recruitment
Feasibility to recruit to the study.
Time frame: 6 months
Tolerability of Low dose Radiotherapy
Proportion of patients with no decline in PaO2/FiO2 ratio (P/F Ratio) at 48 hours after each fraction of radiotherapy
Time frame: 48 hours
Withdrawal
The number of patients who withdraw from the study
Time frame: 6 months
Adverse events
The number of Grade 4 or higher CTCAE v5 (apart from asymptomatic lymphopenia) adverse events reported
Time frame: 1 month
Feasibility of biochemical analysis
Ability to perform lymphocyte subset, IL-6, and IL-10 analysis at baseline and 7 days post last fraction of radiotherapy
Time frame: 1 week
Plan to share: No — All data will be kept anonymized and confidential. Data will be held securely for 15 years pending further study.
