Study Title:

A RANDOMIZED, DOUBLE-BLIND, Placebo-Controlled, MULTICENTER STUDY TO EVALUATE THE EFFICACY AND SAFETY OF TOCILIZUMAB IN HOSPITALIZED PATIENTS WITH COVID‑19 PNEUMONIA

Study Objectives:

Objectives and Endpoints

This study will evaluate the efficacy and safety of tocilizumab (TCZ) compared with a placebo in combination with SOC in hospitalized patients with COVID-19 pneumonia.  To enhance the understanding of the clinical profile of tocilizumab for patients who belong to high-risk and minority populations, an emphasis will be placed on including minority-enrolling sites.  Specific objectives and corresponding endpoints for the study are outlined below.

Efficacy Objectives

Primary Efficacy Objective

The primary efficacy objective for this study is to evaluate the efficacy of TCZ compared with placebo in combination with standard of care (SOC) for the treatment of COVID-19 pneumonia on the basis of the following endpoint:

  • Cumulative proportion of patients with death or requiring mechanical ventilation by Day 28

 

Secondary Efficacy Objective

The secondary efficacy objective for this study is to evaluate the efficacy of TCZ compared with placebo in combination with SOC for the treatment of COVID-19 pneumonia on the basis of the following endpoints:

  • Time to improvement of at least 2 categories relative to baseline on a 7-category ordinal scale of clinical status
  • Time to clinical failure, defined as the time to death, mechanical ventilation, intensive care unit (ICU) admission, or withdrawal (whichever occurs first)
  • Mortality rate by Day 28
  • Time to hospital discharge or “ready for discharge” (e.g., awaiting social disposition) as evidenced by, for example, normal body temperature and respiratory rate, and stable oxygen saturation on ambient air or £2L supplemental oxygen

 

Exploratory Efficacy Objective

The exploratory efficacy objective for this study is to evaluate the efficacy of TCZ compared with placebo in combination with SOC for the treatment of COVID-19 pneumonia on the basis of the following endpoints:

  • Change from baseline in inflammatory markers levels (high sensitivity C-reactive protein [hs-CRP]/C-reactive protein [CRP], D-dimer, and ferritin) over time
  • Cumulative proportion of patients requiring CPAP or BIPAP by Day 28

 

Safety Objective

The safety objective for this study is to evaluate the safety of TCZ compared with placebo in combination with SOC for the treatment of COVID-19 pneumonia on the basis of the following endpoints:

  • Incidence and severity of adverse events, with severity determined according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
  • Incidence of any post-treatment bacterial and/or fungal infection
  • Incidence of any post-treatment acute kidney injury (defined by 50% increase of creatinine from baseline)
Laymans Summary:

There are currently no drugs licensed for the treatment of patients with COVID-19. Given the results of available data, Tocilizumab, along with standard of care (SOC) supportive treatment, could provide benefit, offering the potential to treat COVID-19 in hospitalized populations more effectively than current Standard Of Care (best practice supportive treatment) alone. Extensive safety data has previously been generated on the use of Tocilizumab in other indications e.g. for rheumatoid arthiritis as registered in Kenya. Therefore, this study will look at comparing a combination of Tocilizumab with Standard Of Care supportive treatment to assess safety and efficacy of Tocilizumab in hospitalized patients with COVID-19 pneumonia, and this rationale is justified to address the high unmet need and burden of disease in this severely ill population for which there is no current known better treatment options. 

 

1 Dear EEC reviewers, There is no change to the protocol or study design. This is a notification of final EC-approved ICFs, rendering use of ICF Version 4 as the final approved consent form that will be used for patients. Following the concurrent and extensive review by the PPB EEC and AKUH EC, there was one additional change requested by the AKUH EC to be made to the ICFs. This was to change the phrase "standard of care" to "best practice" as the EC clarified that there is no current standard of care for covid19, and the care provided to patients should be worded as best practice of clinical care currently known. The EC reviewed and approved site specific addendum and ICF's Version-4 are attached in the notification section of this amendment for your records. Many thanks Kind regards, Dr. Huwaida.
