About this study

Official title: Immunoregulatory Therapy for 2019-nCoV-induced Severe Pneumonia Patients

Sepsis, including viral infections, are major causes of death worldwide. Studies show that in 2017, the number of sepsis patients worldwide reached as high as 48.9 million, of which 11 million patients died. Studies in China also showed that more than 1 million patients died of sepsis in 2015. Previous studies have suggested that sepsis are often secondary to excessive inflammatory response syndrome. However, treatment measures targeting excessive inflammatory response failed to effectively improve the prognosis of patients. PD-1 and PD-L1 are key mediators in T cell depletion in sepsis patients. Therefore, the investigators try to performe a clinical research to investigate the efficacy of PD-1 and thymosin in patients with severe pneumonia associated with lymphocytopenia in 2019 novel coronavirus infection.

Read the detailed description

Sepsis, including viral infections, are major causes of death worldwide. Studies show that in 2017, the number of sepsis patients worldwide reached as high as 48.9 million, of which eleven million patients died. Studies in China also showed that more than one million patients died of sepsis in 2015. Therefore, how to effectively reduce the mortality of patients with sepsis has become a focus of clinical and basic research.

Previous studies have suggested that sepsis are often secondary to excessive inflammatory response syndrome. However, treatment measures targeting excessive inflammatory response failed to effectively improve the prognosis of patients. The reason is that sepsis-related immune dysfunction can increase the risk of secondary infection and even affect the fatality rate.

The immune checkpoint pathway is the endogenous component of the immune system, which is responsible for checking the immune response and keeping it in a normal physiological state. Tumor cells can evade host recognition through this pathway. One of these immunocheckpoint pathways is the PD-1 and PD-L1 pathways. PD-1 is a receptor expressed on the surface of T cells and ACTS as a negative regulator of T cell function. Monoclonal antibody blocking the activity of PD-1 can successfully reduce tumor load and has been widely used in the clinical treatment of various tumors.

The immune imbalance in patients with sepsis has many similarities tumors. PD-1 and PD-L1 are key mediators in T cell depletion in sepsis patients. Animal models have shown that blocking PD-1 or PD-L1 can prevent T cell death, regulate cytokine production, reduce organ dysfunction and reduce death in sepsis. Previous study showed the clinical safety of anti-PD-1 antibody in sepsis patients through randomized, placebo-controlled trials.

Thymosin has also been proved to regulate cellular immunity in sepsis patients. Some studies have shown that thymosin can significantly reduce the mortality of sepsis patients. At present, phase III clinical research is in progress to further clarify the role of thymosin in patients with sepsis. The purpose of this study was to investigate the efficacy of PD-1 and thymosin in patients with severe pneumonia associated with lymphocytopenia in 2019 novel coronavirus infection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. lung injury score

    proportion of lung injury score decreased 1 or more points

    Measured: 7 days

Secondary outcomes (6)
  1. absolute lymphocyte counts

    lymphocyte counts at day 7, 14 and 28 after randimization

    Measured: 7, 14 and 28 days

  2. serum level of CRP, PCT and IL-6

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PD-1 blocking antibody+standard treatment, Thymosin+standard treatment and standard treatment in people with 2019 nCoV, PD-1, run by Southeast University, China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

lung injury score (time frame: 7 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2020.
