Clazakizumab vs. Placebo - COVID-19 Infection
What this study is about
The purpose of this study is to investigate the effectiveness and safety of treatment with clazakizumab compared to a placebo (inactive substance). We are proposing to try this drug to treat coronavirus disease 2019 (COVID-19) infection. Patients with COVID-19 infection have been shown to have increases in certain inflammatory processes.
View original scientific description
The purpose of this study is to investigate the effectiveness and safety of treatment with clazakizumab compared to a placebo (inactive substance). We are proposing to try this drug to treat coronavirus disease 2019 (COVID-19) infection. Patients with COVID-19 infection have been shown to have increases in certain inflammatory processes. Clazakizumab is an antibody (immune system protein) that blocks certain inflammatory processes. The treatment plan is to attempt to inhibit or block these inflammatory processes in order to try to limit the damage COVID-19 causes to the lungs.

- Evidence of pulmonary involvement with at least 2 of the following:
- oxygen saturation at rest in ambient air with peripheral capillary oxygen saturation (SpO2) ≤ 94%
- tachypnea with resting respiration rate \> 25 breaths/minute
- Partial pressure of oxygen (PaO2)/initial fraction of inspired oxygen (FiO2) ≤ 300 mmHg
- Chest imaging (radiograph, CT, or ultrasound) with abnormalities consistent COVID-19 pneumonia
Exclusion criteria
- Previous hypersensitivity or allergic reactions to clazakizumab
- Lactating or pregnant females
- Patients with latent tuberculosis (TB) and who are not receiving treatment
- Patients with active TB
- Patients with known active inflammatory bowel disease, untreated diverticulitis, or gastrointestinal perforation
- Requiring mechanical ventilation or extracorporeal membrane oxygenation (ECMO)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
