Background and study aims
COVID-19 is a condition caused by the coronavirus (called SARS-CoV-2) that was first identified in late 2019. This virus can infect the respiratory (breathing) system. Some people do not have symptoms but can carry the virus and pass it on to others. People who have developed the condition may develop a fever and/or a continuous cough among other symptoms. This can develop into pneumonia. Pneumonia is a chest infection where the small air pockets of the lungs, called alveoli, fill with liquid and make it more difficult to breathe.
In 2020, the virus has spread to many countries around the world and neither a vaccine against the virus or specific treatment for COVID-19 has yet been developed. As of March 2020, it is advised that people minimize travel and social contact, and regularly wash their hands to reduce the spread of the virus.
Groups who are at a higher risk from infection with the virus, and therefore of developing COVID-19, include people aged over 70 years, people who have long-term health conditions (such as asthma or diabetes), people who have a weakened immune system and people who are pregnant. People in these groups, and people who might come into contact with them, can reduce this risk by following the up-to-date advice to reduce the spread of the virus.
This study is designed to evaluate the potential ability of the study drug CYT107 to reduce the extent of Intensive Care Unit treatment required and mortality in COVID -19 patients. We believe CYT107 will achieve this by reversing conditions called lymphopenia (where patients have abnormally low levels of white blood cells called lymphocytes) and T cell exhaustion (which prevents the body from dealing with chronic viral infections.
Who can participate?
Hospitalized patients aged 18 - 85 with confirmed low white blood cell count and COVID-19.
What does the study involve?
Participants will be randomly allocated to receive CYT107 or a placebo every 3 - 4 days for 14 days.
What are the possible benefits and risks of participating?
Benefits: possible improvement in immunity.
Risks: possible side effects from the experimental product. These will be closely monitored at all times.
Where is the study run from?
Guy’s Hospital (UK)
When is the study starting and how long is it expected to run for?
May 2020 to March 2024

| Scientific title | InterLeukin-7 (CYT107) to Improve Clinical Outcomes in Lymphopenic pAtients With COVID-19 Infection UK Cohort (ILIAD-7-UK) |
| Study acronym | ILIAD-7-UK |
| Study objectives | Comparison of the effects of CYT107 vs Placebo administered IM at 10µg/kg twice a week for two weeks on immune reconstitution of lymphopenic COVID-19 patients. The aim of the study is to test the ability of CYT107 to produce an immune reconstitution of these patients and observe possible association with a clinical improvement |
| Ethics approval(s) | Approved 06/05/2020, (London - Central Research Ethics Committee, 3rd Floor, Barlow House, 4 Minshull Street, Manchester, M1 3DZ, UK; +44 (0)207 1048138; londoncentral.rec@hra.nhs.uk), ref: 20/HRA/2191 |
| Health condition(s) or problem(s) studied | Lymphopenic COVID-19 patients |
| Intervention | Approximately 48 participants will be randomized 1:1 to receive (a) Intramuscular (IM) administration of CYT107 at 3 μg/kg followed, after 48 h of observation, by 10 μg/kg twice a week for 2 weeks or (b) Intramuscular (IM) placebo (normal saline) at the same frequency An interim safety review will take place after the first 12 patients. If the CYT107 is well tolerated, the test dose (3 μg/kg) will cease and that initial dose will become the same as the rest of the doses (10 μg/kg). So, the remaining patients will be randomized to receive 5 administrations of (a) CYT107 at 10 μg/kg every 3 to 4 days for 2 weeks or (b) Intramuscular (IM) placebo (normal saline) at the same frequency The randomization list will comprise two arms, CYT017 and Placebo. Randomization will be organized to allow a stratification based on certain co-treatments (anti-virals), age (<60 or ≥60) and gender. We anticipate that during the course of the trial some COVID-19 antivirals may give clear sign of activity. Also, these patients often receive anti-IL-6 or anti-IL-6R antibodies. Such pretreatments or co-administration interventions will be recorded at inclusion and the randomization center will include this information, together with gender, to organize the stratification by appropriate randomization in order to equilibrate the two groups for these co-factors. Subjects will be allocated randomly within each block. This procedure will be repeated until at least 24 subjects have completed the active Study treatment for the CYT107 cohort and 24 subjects have completed Study treatment for the control (placebo) group, totaling at least 48 subjects. After randomization authorization is granted by the PI at the responsible institution, the randomization assignment will be generated by computer, using an alpha-numeric ID number to identify each site. Subjects, investigators, and all Study team members will be blinded to drug treatment. Subjects withdrawn prior to randomization (prior to receiving CYT107 or placebo) will be replaced with the next subject recruited, who will receive the same randomization assignment. |
