Enrollment: 20
Healthy volunteers: no

Brief summary:
This protocol will evaluate the efficacy of Therapeutic Plasma Exchange (TPE) alone or in combination with ruxolitinib in COVID positive patients with PENN grade 2, 3, 4 cytokine release syndrome (CRS). It is hypothesized that dual intervention of acute apheretic depletion of cytokines and concomitant suppression of production will produce superior amelioration of the cytokine load and to help to prevent cytokine load rebound. This protocol is envisioned as a pilot study (n=20) for hypothesis generation for future investigation.

Detailed description:
A virally mediated pandemic of 2020 is linked to a novel Beta Coronavirus (COVID-19) sharing subgenus classification with the severe acute respiratory syndrome (SARS) virus. The predominant modes of transmission are respiratory aerosolization and contaminated surface contact. COVID-19 infection is characterized by a wide range of severity and disease manifestations from asymptomatic to respiratory and multi organ failure. Definitive treatment is lacking, but there is an increasing awareness of its associated systemic cascade of inflammatory molecules that offers avenues to explore therapeutically.

Therapeutic plasma exchange (TPE) offers an immediate and scientifically grounded intervention for the removal of a host of pathogenic antibodies and toxic molecules by centrifugal separation of plasma or plasma membrane filtration. TPE in conjunction with Tocilizumab and steroids has been used successfully in the management of severe cytokine release syndrome (CRS) following chimeric antigen receptor T-cell therapy (CAR-T).

Precedence for consideration of TPE in a variety of inflammatory dominant disease states is also well known. Interest in adjuvant treatment for management of sepsis and multi organ dysfunction has been studied. TPE has also been used in three pediatric patients with pH1N1 influenza A acute respiratory failure and hemodynamic shock despite failure of best supportive care. All three survived with "good functional recovery."

Ruxolitinib is a Janus kinase (JAK) and signal transducer and activator of transcription (STAT) (JAK/STAT) pathway inhibitor which is FDA approved for polycythemia rubra vera, myelofibrosis and graft versus host disease. A murine model of CRS following CAR-T cellular therapy has been developed showing marked elevation of interleukin-6 (IL-6), interferon-gamma, tumor necrosis factor (TNF) alpha mimicking human CAR-T therapy induced CRS. Ruxolitinib treated mice demonstrated clinical amelioration and decrement in inflammatory cytokines. Incyte Corporation has announced plans to launch a Phase III trial of single agent ruxolitinib for COVID-19 associated cytokine storm.

Background and Rationale 
A virally mediated pandemic of 2020 is linked to a novel Beta Coronavirus (COVID-19) sharing 
subgenus classification with the SARS virus. The predominant modes of transmission are 
respiratory aerosolization and contaminated surface contact.1,2 COVID-19 infection is 
characterized by a wide range of severity and disease manifestations from asymptomatic to 
respiratory and multi organ failure. Definitive treatment is lacking, but there is an increasing 
awareness of its associated systemic cascade of inflammatory molecules that offers avenues to 
explore therapeutically. 
P. Conti3 and colleagues have recently outlined the binding of COVID-19 to the Toll-like receptor 
(TLR) with subsequent multi step generation of mature IL-1 β to trigger fever and pneumonitis. 
Many investigators draw similarity to the evolving understanding of cytokine storm or the cytokine 
release syndrome. Mehta et al4 note the resemblance of severe COVID-19 expression to secondary 
hemaphagocytic lymphohistiocytosis (sHLH) long regarded as a fatal hypercytokinemic state with 
excessive elaboration of IL2, IL-7 TNF and macrophage inflammatory protein 1-alpha among 
others. 
Therapeutic plasma exchange (TPE) offers an immediate and scientifically grounded intervention 
for the removal of a host of pathogenic antibodies and toxic molecules by centrifugal separation of 
plasma or plasma membrane filtration. Xiao5 and colleagues successfully incorporated TPE in the 
management of a patient with severe CRS following CAR-T treatment in conjunction with 
Tocilizumab and steroids with daily documentation of cytokine levels. 
Precedence for consideration of TPE in a variety of inflammatory dominant disease states is well 
known. Interest in adjuvant treatment for management of sepsis and multi organ dysfunction is 
reflected in Busund6 and Rimmer7 manuscripts. Patel et al8 successfully used TPE in three pediatric 
patients with pH1N1 influenza A acute respiratory failure and hemodynamic shock despite failure 
of best supportive care. All three survived with “good functional recovery.” 
Ruxolitinib is a JAK/STAT pathway inhibitor which is FDA approved for polycythemia rubra vera, 
myelofibrosis and graft versus host disease. Kenderion et al9 reported a murine model of CRS 
following CAR-T cellular therapy with marked elevation of IL-6, interferon-gamma, TNF alpha 
mimicking human CAR-T therapy induced CRS. Ruxolitinib treated mice demonstrated clinical 
amelioration and decrement in inflammatory cytokines. Incyte Corporation has announced plans to 
launch a Phase III trial of single agent ruxolitinib for COVID-19 associated cytokine storm. 
This protocol will evaluate the efficacy of TPE alone or in combination with ruxolitinib in COVID 
positive patients with PENN grade 2, 3, 4 CRS. It is hypothesized that dual intervention of acute 
aphaeretic depletion of cytokines and concomitant suppression of production will produce superior 
amelioration of the cytokine load and to help to prevent cytokine load rebound. This protocol is 
envisioned as a pilot study (n=20) for hypothesis generation for future investigation.

Risk Analysis 
The proposed patient population is not anticipated to be at an increased risk compared to a clinically 
similar population without COVID-19 infection. The device and drug will be used as marketed. 
Standard risks for the device and drug are outlined in the patient informed consent document. Risks 
will be minimized by conducting the trial in the inpatient setting of an acute care hospital with 
dedicated and trained therapeutic apheresis staff, licensed medical personnel and experienced 
research team members under the direction and oversight of the principal investigator. In the event 
of patient status improvement, discharge will be acceptable after completion of therapeutic plasma 
exchange.  Daily outpatient follow-up through patient completion of study required assessments 
will occur in a dedicated phase I research unit. 
 
Removal of medications with TPE is a risk.  However, consultation with a hospital pharmacist will 
occur as needed to determine if a change in timing of medication administration is needed or if 
medication reloading should occur post TPE.

Dose Modifications 
The starting dose of ruxolitinib is 5mg po bid.  The need for dose adjustments will be assessed on a 
daily basis by the research team and pharmacist. 
 AST/ALT > 5x ULN, reduce dose of ruxolitinib to 5mg po once daily11 
 Platelet count between 25,000 and 35,000, reduce dose of ruxolitinib to 5mg po once daily.  
Platelet count < 25,000, hold ruxolitinib. May resume once platelet count >25,000 with 
dosing based on actual platelet count. 
 Absolute neutrophil count < 500, hold ruxolitinib until > 500 then resume at full dose 
 Creatinine Clearance <15ml/min, discontinue ruxolitinib 
 
Duration of Investigations 
A six month patient recruitment period is anticipated. Patient participation is 15 days in duration. 
An additional six month period of data analysis is anticipated for an overall period of investigation 
equaling 12 months 
 
Treatment Discontinuation 
Treatment discontinuation will occur under the following conditions: 
 The patient withdraws consent either from treatment or from the study 
 The patient is lost to follow-up 
 The patient experiences a side effect that per the protocol requires treatment to end 
 The physician deems treatment discontinuation is in the best interest of the patient 
 The patient is found to be eligible to participate in the study after being enrolled and 
continued treatment in this study is not in the best interest of the patient 
 The patient is found to be pregnant or intends to become pregnant 
 The patient is noncompliant with the study requirements your disease worsens 
 
Data Handling and Recordkeeping 
The principal investigator will carefully monitor study procedures to protect the safety of 
research subjects, the quality of data, and the integrity of the study. All study subject 
material will be assigned a unique identifying code or number. The key to the code will be 
kept in a locked file in the Research Division of the Prisma Health Cancer Institute. 
 
Data Collection, Analysis and Outcomes 
REDCap EDC software will be used for data management and future statistical analysis. 
Designated Cancer Institute research staff will perform extraction of patient records. 
Overall Response Rate (ORR) will be defined as > 33% decrease in the cytokine load from 
peak value through study day 14 in one-third or more participants. 
 
Ethical Considerations 
This study will be conducted in accordance will all applicable government regulations and 
Prisma Health research policies and procedures. This protocol and any amendments will be 


Page 8 of 14 
 
submitted and approved by the Prisma Health Institutional Review Board (IRB) prior to any 
study activity. 
All study participants will provide informed consent allowing for their tissue and de- 
identified clinical information to be used for research purposes. 
 
Safety Monitoring and Reporting 
A Drug Safety Monitoring Board (DSMB) will be established consisting of a hematologist, 
pulmonologist and infectious disease specialist not associated with the research team for this 
investigation.  The committee will review all serious adverse events within 48 hours and 
will review all patient outcomes for cohort 1a before proceeding to enrollment of cohort 1b. 
 
Adverse Events 
Adverse events (AEs) are defined as an unexpected medical problem that happens during 
treatment with a drug or other therapy.  The NCI Common terminology criteria for adverse 
events (CTCAE Version 5.0) will be used as the standardized severity grading system.  AEs 
will also be reported by degree of relatedness as not related, possibly related, likely related or 
related to the study drug or study therapy. 
 
SAE Reporting to Incyte 
The Principal Investigator (PI) must report all Serious Adverse Events (SAEs) to Incyte 
within 24 hours of learning of an event, regardless of the PI’s causality assessment. This 
notification will be provided on a completed Serious Adverse Event (SAE) form. SAE 
reporting for each subject begins the day the informed consent is signed by the patient and 
within 30 days after subject has completed or discontinued from the study or has taken last 
dose of the study drug, or as described in the protocol. 
SAEs, occurring using Incyte study drug, are reported in accordance with the effective 
protocol. SAEs occurring with any other commercial drug are reported to the manufacturer 
of that drug in accordance with regulations and protocol. 
Initial SAEs and/or subsequent follow-up reports will be reported via email to 
SafetyReporting@Incyte.com or fax (+) 1-866-981-2057.  SAE reports should be for a 
single subject. SAE forms should be sent with a cover sheet and any additional attachments. 
All adverse event information is reported to Incyte on MedWatch Form FDA 3500A. The 
Principal Investigator does not provide medical records (e.g., discharge summary) to Incyte, 
unless specifically requested. 
In addition, all SAEs will be reported to the Prisma Health IRB per the institutional policy for 
reporting. 
Reporting of Pregnancy to Incyte 
An “Initial Pregnancy Report” or equivalent must be completed in full and emailed to 
SafetyReporting@Incyte.com or faxed to (+) 1-866-981-2057 within 24 hours of discovery 
of a pregnancy of a subject who has taken the Incyte product or the pregnancy of a partner 


Page 9 of 14 
 
for a subject who has taken the Incyte product. The “Follow-up Pregnancy Report Form” or 
equivalent must be completed and emailed to SafetyReporting@Incyte.com or faxed to (+) 
1-866-981-2057 within 30 days after delivery, so that Incyte is provided with information 
regarding the outcome of the pregnancy. If the pregnancy results in any events which meet 
the serious criteria (i.e., miscarriage or termination), the SAE reporting process needs to be 
followed and the timelines associated with a SAE should be followed. 
 
Statistical Analyses 
 
General Statistical Considerations 
Standard statistical methods will be employed to analyze all data.  It is anticipated that the 
following techniques may be used: descriptive statistics, t-test, Chi-square, Fisher’s exact test, 
Kaplan-Meier analysis, and graphical displays.  This protocol may not reflect all analyses 
planned for the study; additional analyses may be conducted for observational purposes only.   
 
Summary statistics will consist of numbers and percents of responses in each category for 
discrete measures, and of mean, n, standard deviation, median, minimum, maximum and 95% 
confidence intervals for continuous measures. 
 
Sample Size Determination 
The initial sample size is 20.  Each cohort will enroll 10 patients.  This number is considered 
sufficient for an exploratory pilot study to provide information for planning further 
investigations. 
 
Analysis of Safety 
The safety evaluation will compare the proportion of Subjects in each treatment group who 
exhibit treatment-related adverse effects.  These adverse events will be presented for individual 
patients as a listing of events. 
 
Dissemination of Results 
Results of this study may be used for presentations, posters, publications, or extramural 
grant applications. The publication will not contain any identifiable information that could 
be linked to a study patient.
