This phase II expanded access trial will study how well tocilizumab works in reducing the serious symptoms including pneumonitis (severe acute respiratory distress) in patients with cancer and COVID-19. COVID-19 is caused by the SARS-CoV-2 virus. COVID-19 can be associated with an inflammatory response by the immune system which may also cause symptoms of COVID-19 to worsen. This inflammation may be called "cytokine storm," which can cause widespread problems in the body. Tocilizumab is a medicine designed to block the action of a protein called interleukin-6 (IL-6) that is involved with the immune system and is known to be a key factor for problems with excessive inflammation. Tocilizumab is effective in treating "cytokine storm" from a type of cancer immunotherapy and may be effective in reducing the inflammatory response and "cytokine storm" seen in severe COVID-19 disease. Treating the inflammation may help to reduce symptoms, improve the ability to breathe without a breathing machine (ventilator), and prevent patients from having more complications.
PRIMARY OBJECTIVES:
I. To enhance access to tocilizumab for patients who cannot participate in the randomized
COVACTA trial with specific emphasis on patients with cancer, especially those who belong to
high-risk and minority populations and children.
II. To provide observations on clinical outcomes associated with tocilizumab administration
in cancer patients with severe acute respiratory syndrome (SARS) coronavirus 2 (COVID-19)
disease.
SECONDARY OBJECTIVE:
I. To estimate the proportion of patients whose level of institutional care does not further
escalate following administration of tocilizumab.
EXPLORATORY OBJECTIVES:
I. To estimate the number of days intensive care unit (ICU) patients spent in the ICU.
II. To evaluate the mortality rate of patients:
IIa. 30-day and 60-day mortality in patients in the ICU.
IIb. Evaluate the 14-, 30- and 60-day mortality rate following infusion of tocilizumab.
III. To evaluate overall survival.
IV. To describe the proportion of patients progressing to ventilator support after
tocilizumab therapy.
V. Evaluate the clinical course following administration of tocilizumab.
Va. To evaluate the development of additional infections.
Vb. To evaluate the side effects following tocilizumab.
Vc. To evaluate impact on inflammatory markers.
VI. Evaluate the duration of time:
VIa. To removal from mechanical ventilator support.
VIb. To step-down of institutional care requirements.
VIc. To discharge from the ICU to lower level.
VId. To hospital discharge.
VIe. To resolution of clinical symptoms.
VIf. To time of defervescence.
VIg. To normalization of disease-related laboratory abnormalities.
VII. Exploratory biologic correlates.
VIIa. To evaluate cytokine levels pre and post-tocilizumab, specifically evaluating IL-6.
VIIb. To evaluate SARS-coronavirus (CoV)-2 viral loads pre and post-tocilizumab.
VIIc. To determine the pharmacokinetics of tocilizumab in order to facilitate
exposure-response analysis.
VIId. To correlate clinical outcomes with changes in cytokine levels and SARS-CoV-2 viral
loads.
OUTLINE:
Patients receive tocilizumab intravenously (IV) over 60 minutes. A second dose may be given
if there is sustained or recurrent fever, no decrease or not more than a 1-category
improvement on the 7-category ordinal scale (only stabilization or partial improvement
following first dose), or a >= 1-category worsening on the 7-category ordinal scale from
nadir.
After completion of study treatment, patients are followed up for at least 60 days, and, when
possible, up to 1 year.
Biological: Tocilizumab
Given IV
Other Name: Array
Inclusion Criteria:
- Subjects must have an active cancer diagnosis or have completed therapy within 12
months of initiation of protocol specified therapy. This includes:
- Subjects with a new cancer diagnosis who have not yet initiated cancer therapy
- Subjects on active or have recently completed cancer-directed therapy including
chemotherapy, radiation therapy, immunotherapy or hormonal therapy amongst others
- Myelosuppressive chemotherapy for patients in remission (e.g., adjuvant
chemotherapy for breast cancer, acute myeloid leukemia [AML] consolidation)
is prohibited until clinical recovery (1 or 2 on the 7-category ordinal
scale)
- Subjects on any investigational therapy for their underlying cancer,
investigational COVID-19 anti-viral agents, or convalescent serum aimed at
treating COVID-19 disease are eligible. Investigators are reminded to check
whether the other investigational study(s) the patient is participating on
specifically exclude tocilizumab and to adjudicate best clinical management
decision for the specific patient
- Subjects who have undergone hematopoietic stem cell transplant within the past 12
months, or are continued on graft versus host disease (GVHD) therapy, are also
eligible
- COVID-19 Diagnosis: Patients hospitalized with COVID-19 pneumonia confirmed by:
- Radiographic findings concerning for COVID-19 pneumonia AND
- Confirmatory SARS-CoV-2 positive result using any testing assay, or (with or
without a confirmatory test) with suspicion of COVID-19 disease owing to
belonging to a high-risk demographic group or living and/or working in high-risk
settings or with known exposure AND
- Oxygen saturation (SpO2) on room air =< 93% or PaO2/FiO2 < 300 mmHg
- Age >= 2 years

administer tocilizumab
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 10 x
institutional upper limit of normal
- Patients with low blood counts attributable to cancer therapy or underlying malignancy
are eligible
- Patients may be on other therapies for COVID-19 including investigational and not
limited to corticosteroids, azithromycin, chloroquine, hydroxychloroquine
- For patients already enrolled on other investigational studies for COVID-19,
study investigators should verify that co-enrollment on this study is permissible
as per the eligibility of the other study
- Human immunodeficiency virus (HIV)-infected patients are eligible for this trial
