Laboratory parameters predicting mortality of adult in-patients with COVID-19 associated cytokine release syndrome treated with high-dose tocilizumab

AbstractLarge randomized clinical trials in severe Coronavirus Disease 2019 (COVID-19) patients have proven efficacy of intravenous tocilizumab. Our aim was to describe the laboratory parameters predicting in-hospital mortality of patients with tocilizumab administration in COVID-19 associated cytokine release syndrome (CRS).We evaluated high-dose (8 mg/kg) intravenous tocilizumab administration in severe and critically ill COVID-19 adult patients fulfilling predefined strict CRS criteria. A single-centre, prospective, observational cohort study was carried out among consecutive adult (≥18 years of age) in-patients with COVID-19 between April 1 and December 31, 2020. The primary endpoint was 28-day all-cause mortality. The changes in laboratory parameters from baseline on day 7 and 14 after administration of tocilizumab were analysed.In total, 1801 patients were admitted to our centre during the study period. One hundred and six patients received tocilizumab, and among them 62 (58.5%) required intensive care unit admittance while 25 (23.6%) deceased. At day 7 after tocilizumab administration, inflammatory markers (CRP, IL-6, ferritin) and lactate dehydrogenase (LDH) values were significantly lower among survivors. Subsequently, at day 14, differences of IL-6 and LDH levels has become more pronounced between subgroups. Restoration of absolute lymphocyte count (ALC) by day 7 and 14 was insufficient among patients who died.In our cohort, administration of high-dose tocilizumab for COVID-19 patients with CRS demonstrated clinical and sustained biochemical parameter improvement in 76.4%. In this patient population high and increasing LDH, IL-6, and low ALC levels had a predictive role for mortality.

Prophylactic Administration

Currently, only a few reports exist on the cytokine release syndrome (CRS) as one of the severe immune-related adverse events (irAEs) induced by immune checkpoint inhibitors (ICIs). Notably, it is very rare that grade 4 CRS related to ICI therapy overlaps with the drug-induced hypersensitivity syndrome (DiHS). A 46-year old woman with metastatic kidney cancer had grade 3 interstitial pneumonitis induced by four cycles of combination therapy of anti-programmed death-1 and anti-cytotoxic T lymphocyte-4 antibodies after right cytoreductive nephrectomy. Prophylactic administration of trimethoprim/sulfamethoxazole (TMP/SMX) was started concomitantly with prednisolone therapy to treat the interstitial pneumonitis. She developed hypotensive shock when reducing the dosage of prednisolone, and required intubation and ventilation using vasopressors at the intensive care unit. She subsequently exhibited prominent leukocytosis and an increased level of C-reactive protein, suggesting markedly increased cytokine levels. Interestingly, facial edema and erythema increased in association with pyrexia, leukocytosis, liver dysfunction, and renal failure, suggesting that she developed DiHS. She received hemodialysis three times, a plasma exchange, and anti-interleukin-6 therapy to treat severe renal dysfunction, a thrombotic thrombocytopenic purpura-suspected condition, and possible grade 4 CRS, respectively. Although these therapies did not elicit sufficient effects, high-dose administration of intravenous immunoglobulin was successful. With steroid mini-pulse therapy and the subsequent administration of prednisolone, she recovered successfully. To the best of our knowledge, this is the first report that ICIs and TMP/SMX can induce hypotensive shock accompanied with CRS and DiHS during immunosuppressive therapy for an irAE. Importantly, the prophylactic administration of TMP/SMX should be performed cautiously to avoid severe drug reactions such as CRS or DiHS.

Mixed Efficacy

As cases of coronavirus 2019 (COVID-19) keep rising, reported deaths are increasing. Public health measures have been implemented with mixed efficacy. As vaccines are becoming more widely available and accessible globally, treating critically ill COVID-19 patients remains an issue with only dexamethasone found to be therapeutically effective to date. However, trials studying the efficacy of IL-6 inhibitors, namely tocilizumab have been underway with promising results. This paper is a narrative review that aims to review the current evidence provided by randomized clinical trials (RCT) for the use of tocilizumab in COVID-19. Electronic database searches were carried out in Medline, PubMed, Embase, Google Scholar, and ongoing clinical trial registries with the period set from January 1, 2020 to February 20, 2021. Prepublication manuscripts were found using the pre-print repository medRxiv. Keywords included “COVID-19,”“coronavirus,”“SARS-CoV-2,”“sepsis,”“pneumonia,”“cytokine storm,”“cytokine release syndrome,”“IL-6 inhibitors,” and “tocilizumab,” as exact phrases, and a combination of subject headings according to databases syntax. Only trials with a clear and well-defined methodology, at least 100 patients recruited, and which have had results published either after peer review or in pre-print were included. In hospitalized patients with severe COVID-19, who are hypoxic and have a CRP ≥ 75 mg/L, the current evidence favors the use of a combination of tocilizumab and corticosteroids to reduce mortality, among other clinical benefits. There is also overwhelming evidence of the good safety profile of tocilizumab with only few cases of neutropenia reported with a decrease in infection rates. Tocilizumab is currently thought to work through the inhibition of IL-6 receptors (IL-6R), preventing downstream activation of pro-inflammatory reactions and cytokine release syndrome.

Durable Remission

Abstract CTLO19 cells are CAR-modified T cells which recognize CD19 and produce high durable remission rates for pts with relapsed or refractory acute lymphoblastic leukemia (ALL). Cytokine Release Syndrome (CRS) has emerged as the major treatment related effect from CTL019, with symptoms that include high fevers and malaise but can progress to capillary leak, hypoxia and hypotension. CRS occurs hours to days after CTL019 infusion and correlates with rapid in vivo CTL019 expansion and marked elevation of serum IL6. In most cases, CRS is self-limited or rapidly reversed with anti-cytokine directed therapies. Here we report 3 cases of refractory CRS in adult pts with ALL. Our experience offers insight into clinical and investigational parameters describing this syndrome; highlights the variance of CRS across disease types and illustrates complexities of CRS management during concurrent infectious illness. As of 7/1/14, 97 pts (30 pediatric ALL, 12 adult ALL, 41 CLL, 14 NHL) have been treated with CTLO19. To capture clinical manifestations of CRS across protocols, we developed a novel CRS grading scale which will be described. Severe CRS (Gr 3-5) occurred in 27 (64%) of ALL pts and only 16 (29%) of CLL/NHL pts (p=0.001). 12 adults with ALL received CTL019; 8/9 evaluable pts achieved CR (MRD negative) at 1 month and 1 pt with extramedullary disease had marked reduction of PET avid disease which is maintained at 1 yr. Severe CRS occurred in 11 of 12 adult ALL pts. CRS was self-limited in 2 pts, rapidly reversed with anti-IL6 directed therapy in 6 pts and was refractory to therapy, contributing to death in 3 pts who were not evaluable for disease response. No baseline attributes differentiate these 3 pts from the 9 adult ALL pts with manageable Gr1-4 CRS. We have shown however that ALL disease burden correlates with CRS severity (in press) and all 3 pts had significant disease burden at baseline. All received lymphodepleting chemotherapy with cyclophosphamide 300 mg/m2 q12h x 6 followed by infusion of CTLO19 cells. These 3 pts each received 6.50E+06, 6.70E+06 and 8.45E+06 CTLO19 cells/kg compared to median CTL019 dose of 3.62E+06 in the 9 adult ALL pts with manageable CRS. Pt 21413-03 developed CRS 12 hrs after infusion and tested positive for influenza B on D3. Despite broad spectrum antimicrobials (including oseltamivir) and anticytokine directed therapy with tocilizumab (4mg/kg x 2) and steroids, he died with refractory hypotension on D5. Pt 21413-06 had extensive disease after 2 prior allogeneic SCTs and developed CRS within 12 hrs of infusion. In addition to broad spectrum antibiotics, she received tocilizumab 8mg/kg (D 3, 6 and 12); intermittent high dose steroids (D 4-15) and etanercept (D14). She died D15 with hypotension, hypoxic respiratory failure and concurrent MDR pseudomonas sepsis and pneumonia. Pt 21413-11 developed CRS within 24 hrs of infusion. He received tocilizumab 8mg/kg (D3&4); siltuximab (D5&15) and intermittent high dose steroids (D 4-15). After an initial response, he developed recurrent fever, pulmonary infiltrates and blood cultures positive for stenotrophomonas. He died D15 with refractory hypoxia and hypotension. All 3 pts’ clinical CRS correlated with marked in vivo CTL019 expansion and progressive serum cytokine elevations (data to be shown). CONCLUSIONS: CRS is the major toxicity of CTL019 therapy and its clinical course varies depending on disease type (more frequent and severe in ALL) and disease burden (in ALL). The 3 refractory CRS cases described here (of 97 total pts treated) have all occurred in adult ALL pts with significant disease burden who received relatively high doses of CTL019 cells. In addition, all 3 had significant infectious complications which potentially fueled underlying CRS and/or were made more virulent due to impairment of immunity with administration of anti-cytokine directed therapies. Future protocol modifications will be made goal of limiting severity of CRS while maintaining high durable remission rates. Further exploration is planned to better correlate timing and choice of anticytokine directed therapy in relation to clinical and investigation parameters of CRS.

Life Threatening

Three patients with severe life-threatening COVID-19 who failed to achieve substantial improvement on tocilizumab, received pulse therapy with corticosteroids (methylprednisolone, 1000 mg/day IV for three consecutive days) and intravenous immunoglobulin (20 g/day IV). This was associated with a prompt resolution of respiratory failure, elimination of cytokine release syndrome, and reversal of pulmonary CT changes. The treatment was generally safe and well tolerated. There was no evidence of protracted persistence of the virus in the patients who received pulse therapy. Randomized controlled trials are necessary to specify the efficacy and safety of high-dose methylprednisolone and intravenous immunoglobulin in the treatment of severe life-threatening COVID-19 separately or in combination.
