	 	2.6.	 Exercise of Option 



 

	 	(a)	 Licensee may exercise the Option anytime during the Term (“Option Period”).    



  

	 	(b)	 To exercise the Option and begin a sixty (60) day negotiation period with Foundation, an authorized
representative of Licensee shall provide written notice, pursuant to Section 18.5, to Foundation of such desire. With such written notice or concurrent with such written notice if notice is by electronic mail, Licensee shall deliver to

whatsoever in or to Foundation Subject Matter or any Foundation patents or patent applications pertaining to Foundation Subject Matter in the Option Field. Thereupon, Foundation is free to enter into any commercial agreement, option or license
granting rights to Foundation Subject Matter or patents or patent applications pertaining to Foundation Subject Matter in the Option Field with any Third-Party on any terms and conditions.

	3.	 CONSIDERATION AND PAYMENT TERMS

under this Agreement. Licensee will pay Foundation: 
  

	 	3.1.	 Upfront Fee. Within thirty (30) days of the Effective Date, Licensee will pay to Foundation an

	 	3.4.	 Importance of Technical Information and Material. Licensee has requested, and Foundation has agreed, to
grant certain rights to the Technical Information and Materials within the Foundation Subject Matter. Licensee desires these rights in order to develop and commercialize the Foundation Subject Matter. Because of the importance of Technical
Information and Materials, Licensee has agreed to pay certain fees to Foundation on Products or Services, as specified herein, even if it is not covered by a patent or patent application, in order to obtain rights to Technical Information and
Materials. Licensee has agreed to these payments because of the commercial value of Technical Information and Materials, separate and distinct from the existence or rights to any a patent or patent application related to the Foundation Subject
Matter, that Licensee acknowledges would provide a commercial advantage. Licensee acknowledges that it would not have entered into this Agreement without receiving the rights to the Technical Information and Materials within the Licensed Subject
Matter specified in Section 2. Licensee further acknowledges that licenses to Technical Information, Materials, and each patent and application if any are separately available to license, and that for convenience and because of the preference
of Licensee, the parties executed this combined license and option to the Foundation Subject Matter.

refer to U.S. Dollars. Payments with designated payment dates are due and payable on or before those dates. For the avoidance of doubt, Licensee is solely responsible for bank transfer charges, including but not limited to, wire transfer

of withholding, value-added taxes, fees, or other charges imposed by the government of such country, except as permitted in the definition of Net Sales.

commercialization of the Foundation Subject Matter, Services and Products in the License Field throughout the Territory, and the terms in this Section 4 constitute material terms of this Agreement. If Licensee fails to perform any of its
obligations specified in this Article 4, then Foundation will have the unilateral right and option to: (i) terminate this Agreement; or (ii) modify the terms of the Agreement. This right to modify the terms, if exercised by Foundation,

of Payments Due or amounts paid, or to determine compliance with any other obligation(s) of Licensee under this Agreement. Licensee agrees to cooperate fully with the Independent Auditor in connection with such review. 



After completion of any such inspection, Foundation will notify Licensee in writing of any discrepancies in Payments Due or amounts paid to
Foundation. Such inspection will be made at the expense of Foundation, unless such inspection discloses an underpayment discrepancy of five percent (5%) or more in any calendar quarter, or if such underpayment is in excess of $5,000 for any calendar
quarter or an aggregate of $10,000 for any calendar year. In such case, Licensee will be responsible for reimbursing Foundation for the inspection fee and expenses associated with such inspection within thirty (30) days after a written demand
by Foundation. Licensee agrees to pay past due amounts for any deficiency error in Payments Due as determined by the Independent Auditor, including without limitation any payment deficiency since the Effective Date of the Agreement. Any underpayment
as determined by the Independent Auditor will bear interest at one percent (1%) per month from the date the original payment was due. Foundation and the Independent Auditor will maintain in confidence such inspection and the resulting report. The
Independent Auditor may from time to time consult the Foundation and any of its employees or Third Party counsel on questions as they relate to this Agreement. The Independent Auditor may not disclose financial or proprietary information except as

	 	9.1.	 Indemnification. 



 

	 	(a)	 Licensee shall indemnify, defend, and hold harmless Foundation, and its trustees, officers, staff, employees,
students, and agents and their respective successors, heirs, and assigns, and Stony Brook University, and its trustees, officers, staff, employees, students, and agents and their respective successors, heirs, and assigns, (the “Indemnified
Parties”), against any liability, damage, loss, or expense (including reasonable attorneys’ fees and expenses of litigation) incurred by or imposed upon the Indemnified Parties or any one of them in connection with any claims, suits,
actions, demands, or judgments of Third Parties, Affiliates: (i) arising out of the design, production, manufacture, sale, use in commerce or in human clinical trials, lease, or promotion by Licensee or by an Affiliate, or agent of Licensee of
any Product, process or Service relating to, or developed pursuant to, this Agreement; or (ii) arising out of any other activities to be carried out by or on behalf of Licensee pursuant to this Agreement provided that the liability, damage or
loss is not attributable to the negligent activities of such Indemnified Party. 


  

	 	(b)	 Licensee agrees, at its own expense, to provide attorneys reasonably acceptable to Foundation to defend against
any actions brought or filed against any Indemnified Parties with respect to the subject of indemnity to which such Indemnified Parties are entitled hereunder, whether or not such actions are rightfully brought. Foundation will cooperate in the
defense thereof, provided, however, that Foundation will have the right, but not the obligation, to control the defense, at its expense, of any such actions. Foundation and the Indemnified Parties may, at their option and expense, have their own
counsel participate in any proceeding which is under direction of Licensee and will cooperate with Licensee and its insurer in the disposition of any such matter; provided, however, that if Licensee shall not defend such actions or if there exists
an actual or potential conflict of interest that makes representation of Indemnified Parties or Indemnified Parties and Licensee by the same counsel or the counsel selected by Licensee inappropriate, Foundation and the Indemnified Parties shall have
the right to defend such actions themselves and recover from Licensee all reasonable attorneys’ fees and expenses incurred by it during the course of such defense. 



 

	 	(c)	 Neither Foundation, the Indemnified Parties, nor Licensee shall enter into, or permit, any settlement of any
such actions without the express written consent of the other party(ies), which shall not unreasonably be withheld.

commercially distributed or sold, or tested in clinical trials by or on behalf of Licensee, including by its Affiliates, Licensee shall at its sole cost and expense, procure and maintain policies of comprehensive general liability insurance in
amounts not less than (i) five million U.S. Dollars ($5,000,000.00) per incident and five million U.S. Dollars ($5,000,000.00) annual aggregate during the period that such Product, process, or Service is being tested in clinical trials prior to

FDA
		
	Dosage, Route of Administration, and Schedule:	  	Three escalating doses of RLF-100 (Aviptadil): 50, 100, and 150 pmol/kg/hour or placebo administered over 12 hours via IV infusion on successive days. If side effects cannot be managed with
ICU protocol, dose reduced or halted.
		
	Statistical Methods:	  	Primary endpoint (composite) will be displayed by a 2x2 table and analyzed using a logistic regression analysis containing 4 pre-defined baseline covariates and randomized treatment group
(primary) and a two-sided chi square test (secondary). Time to event outcomes will be displayed by a Kaplan Meier lifetable and analyzed by a two-sided log rank test.
Ordinal and continuous outcomes will be assessed by mixed model repeated measures through Day 28. Maximal signal is expected by Day 10. The primary analysis will be based on the modified intent-to-treat (mITT) population.
		
	Sample Size Calculation:	  	Assuming a 25% success percent in the placebo group and a 50% success percent in the RLF-100 group, for a chi square test with two-sided 5% Type 1 error
and 80% power, the sample size to detect a 25% absolute improvement in the composite endpoint (from 25% to 50%) is 144 subjects in the primary analysis group (2:1 randomization favoring the RLF-100 group). A
25% absolute improvement is the composite success percent (25% to 50%) is deemed to be clinically meaningful.

	Interim Analyses	  	An interim look for safety and futility will be conducted once the first 30 randomized subjects complete Day 7. A second interim look for safety, futility, and efficacy will be conducted once 81 subjects complete Day 28. An α
spend is incorporated into the projected sample size to account for the two looks.
		
	Maintenance of Study Blind	  	Investigational drug will be administered in identical infusion bags, labeled by the hospital research pharmacist who is the only unblinded member of the study site. ICU personnel are entirely masked as to treatment assignment, as
are patients. Even in the event of unintentional unblinding because of differential efficacy or safety of the investigational medicinal products (drug and placebo), the randomization scheme prevents staff from knowing the next treatment assignment.
Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff.

	6.	 INTRODUCTION 


  


	6.1	 Executive Summary 



RLF-100 (aviptadil) is a synthetic form of Vasoactive Intestinal Polypeptide (VIP), a ubiquitous,
naturally synthesized human peptide with extensively documented anti-inflammatory, anti-cytokine cascade properties. Prior sponsors have been granted investigational new drug (IND) status by the US FDA and the EMEA for the use of aviptadil in Acute
Respiratory Distress Syndrome (ARDS), Acute Lung Injury (ALI), Pulmonary Fibrosis, and Sarcoidosis. In conjunction with phentolamine, intracavernous aviptadil (InvicorpTM) has been marketed in
Europe for 20 years by Evolan SE for the treatment of erectile dysfunction (ED) with no record of serious adverse events (SAE). At least five well-controlled studies have been conducted for the use of aviptadil in chronic lung conditions. RLF-100 is known to have potent anti-cytokine activity in numerous non-clinical models of ARDS and ALI and has shown early evidence of efficacy in preserving life in patients
with ARDS. A phase 1 safety trial of aviptadil was conducted in eight patients with sepsis-related ARDS, who had an expected 50% mortality rate. Seven patients demonstrated clinical benefit based on improved blood oxygenation and were successfully
withdrawn from advanced life support. Six of those patients survived long term and left the hospital, with one succumbing to an unrelated myocardial infarction at week 3. These results demonstrate in a small sample size that aviptadil significantly
reduced expected mortality in patients with ARDS (mortality reduction of p<.01 vs historical controls). We propose RLF-100 (aviptadil) for the treatment of Critical
COVID-19. 
  

	6.2	 Definition of Critical COVID-19 



In May 2020, FDA defined Critical COVID-19 to be used in clinical trials and disease staging as
follows: 
  

			
	 Critical
 COVID-19
	  	 •   Positive testing by standard
RT-PCR assay or an equivalent test
  

	  	 •   Evidence of critical illness, defined by at least one of the
following:
  

	  	 •   Respiratory Failure defined on resource utilization requiring at least
one of the following:
  

	  	 •   Endotracheal intubation and mechanical ventilation, oxygen delivered by
high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates > 20 L/min with fraction of delivered oxygen 3 0.5), noninvasive positive pressure ventilation,
ECMO, or clinical diagnosis of respiratory failure (i.e., clinical need for one of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation)

 

	  	 •   Shock (defined by systolic blood pressure <90 mmHg, or diastolic blood
pressure <60 mmHg or requiring vasopressors)
  

	  	 •   Multi-organ dysfunction/failure


 Note that treatment with ECMO, mean arterial pressure <65 mmHg on pressors, and Multi-organ failure are
exclusion criteria for this protocol 
 Acute Lung Injury in COVID-19 is characterized by progressive
failure of corporeal oxygenation, attributed on large part by SARS-CoV-2 infection of Alveolar Type II cells (Mason 2020). Extensive nonclinical studies document that
70% of VIP in the body binds to receptors on the Alveolar Type II cell, where VIP is known to block cytokine production and upregulate production of surfactant. 

Severity of COVID is associated with and graded by a progressively worsened state of oxygenation. This is seen in the PaO2/FIO2 ratio, which reflects the status of oxygenation for patients on high pressure oxygen and mechanical ventilation. In patients breathing
room air, disease severity is assessed by SpO2. Many patients with Critical COVID meet the clinical definitions of Acute Respiratory Distress Syndrome (ARDS). However, there is increasing
recognition that respiratory distress in COVID-19 has different characteristics than ARDS in the setting of bacterial sepsis and other common presentations of ARDS. 

The pathologic hallmark of COVID-19 lung injury is diffuse alveolar damage, vascular endothelium
damage, and damage to the surfactant-producing type II cells which results in loss of the integrity of the alveolar-capillary barrier, transudation of protein-rich fluid across the barrier, pulmonary edema, and hypoxemia from intrapulmonary
shunting. Typically, patients who have progressed to Critical COVID-19 require care in an intensive care unit (ICU). The mortality rate is approximately 50%. Deaths usually result from multisystem organ
failure rather than lung failure alone.

	6.3	 RLF-100 Experimental Therapy in
COVID-19 


 Under this protocol, patients with Critical COVID-19 will be randomly allocated to intravenous RLF-100, Aviptadil, with the aim to support pulmonary alveolar function, combat the cytokine-induced inflammation, improve
blood oxygenation, and reduce mortality. 
  

	6.4	 Aviptadil Background 



Aviptadil (vasoactive intestinal peptide; VIP) is an abundant biologically active peptide endogenous in humans as well as in other species. It
is produced by neurons in the peripheral and central nervous system, by endocrine cells such as pituitary lactotrophs, cells of the endocrine pancreas as well as T-lymphocytes, and B-lymphocytes. This natural peptide is one of the signal molecules of the neuroendocrine-immune network comprising vasodilation, anti-proliferative, anti-inflammatory, and immuno-suppressive features. Aviptadil is
predominantly localized in the lungs and a vast body of experimental, pharmacological as well as clinical evidence suggests Aviptadil to be an attractive candidate as a treatment option for acute pulmonary disorders. 

Endogenous aviptadil is synthesized from a precursor molecule which contains 170 amino acids and is processed to its biologically active form
via a signal peptidase in the endoplasmic reticulum and finally cleaved by prohormone convertases and by carboxypeptidase-B like enzymes to functional Aviptadil comprising the following 28 amino acids: His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-
 Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn. 

Aviptadil was first identified in the intestine and then in the central and peripheral nervous systems and has since been recognized as a
widely distributed neuropeptide, acting as a neurotransmitter and neuromodulator in many organs and tissues, including heart, lung, thyroid gland, kidney, immune system, urinary tract and genitals. 

The widespread distribution of aviptadil is correlated with its involvement in a wide variety of physiological activities including smooth
muscle relaxation, increased cardiac output, bronchodilation, immune-modulation, inhibition of smooth muscle cell proliferation, anti-apoptosis, neurotropic effects, and some differential effects on secretory processes in the gastrointestinal tract
and gastric motility. 
 The rationale for the current application can be summarized as follows: aviptadil attenuates, delays or prevents ALI
in various experimental models of ARDS, both in isolated lungs as well as in vivo. Aviptadil protects the heart and other vital organs against oxidative injury and has anti-inflammatory activity against a variety of inflammatory mediators and is
anti-apoptotic. 
  

	6.5	 Clinical Rationale 



Given by intravenous infusion in appropriate concentrations, aviptadil has been shown in clinical trials to have a manageable safety profile
with no observed SAEs to date that would rise to the level of a black box warning. 
  

	7.	 OBJECTIVES 


  

	7.1	 Primary Objective 



The primary objective of this study is to test the hypothesis that RLF-100 + maximal standard of care
(SOC) improves survival and resolves respiratory failure (see Section 6.2) in patients with Critical COVID-19 compared to those treated with placebo + maximal SOC, in both cases not including ECMO. 

  

			
	  	  	Page | 11          















 



 
  


	7.2	 Secondary Objective 



The key secondary objective is to test the hypothesis that RLF-100 decreases respiratory failure as
defined by the FDA May 2020 respiratory failure definition (see Section 6.2). 
  

	8.	 STUDY DESIGN 


  


	8.1	 Overview 



This study, RLF100-001, is a multi-center, randomized double-blind, placebo-controlled phase 2 trial,
comparing RLF-100 + Maximal SOC to placebo + Maximal SOC. Aviptadil or placebo will be administered as a 12-hour IV infusion one thee consecutive days. Primary endpoints
will be measured at ten (10) days post infusion with 28 days of follow-up. Patients with Critical COVID-19 infection will be screened. Informed consent will be
obtained from the patient or a responsible party. Once entered into the study, participants will be randomized in a 2:1 ratio of IV RLF-100 + maximal SOC vs. placebo + maximal SOC. Once enrolled, patients
assigned to receive RLF-100 will be given in three (3) doses of i.v. infusion, each dose given over 12-hour period at the same time on consecutive days, in
escalating doses from 50pmol/kg/hr to 150 pmol/kg/hr of RLF-100. The primary outcome to be measured following RLF-100 infusion is the composite endpoint of “free of
respiratory failure at 10 days and alive at 28 days.”. The declared secondary outcome to be measured following RLF-100 infusion will be Time to resolution of respiratory failure. Respiratory failure is
defined as resource-based according to the FDA May 2020 respiratory failure definition (see Section 6.2). Thirteen other efficacy endpoints are also to be evaluated in support of multi-dimensional efficacy. 

 

	8.2	 Design 



Randomized, prospective, double-blind, placebo-controlled trial of RLF-100 + maximal SOC vs. Placebo +
maximal SOC therapy in patients with Critical COVID-19. 
 Following informed consent, patients will
be randomized and administered either placebo or escalating doses of RLF-100 from 50 pmol/kg/hour IV to 150 pmol/kg/hour as three (3) 12 hour infusions each at the same time of day on subsequent study days 1,
2, and 3. Vital signs and telemetry will be monitored throughout the infusion and for 48 hours after completion of all 3 infusions.. Pulmonary, cardiovascular, hepatic, CNS, renal, and coagulation functions will be assessed daily for 5 days, and
plasma levels of aviptadil and selected cytokines will be measured. 
 The primary efficacy outcome is a
pre-defined composite success endpoint based on milestones achieved during the 28-day follow-up; the secondary outcomes will
include oxygenation levels and severity of organ dysfunction as well as other hospital-based outcome measures. 
 The composite endpoint is
defined as follows and requires both of the following success criteria to be met: 
  

	 	•	 	 Resolution of respiratory failure (no mechanical or non-mechanical
ventilation or high-flow nasal O2) by Day 10, and 


  

	 	•	 	 Alive Day 28. 



The endpoint rationale is to include the FDA required 28-day
all-cause survival outcome plus a resolution of respiratory failure (no mechanical or non-mechanical ventilation or high-flow nasal O2) by Day 10, indicative of respiratory recovery. 
  

	8.3	 Number of Participants 



Initially, randomization will result in 14 participants to receive RLF-100 + SOC and 7 participants to
receive placebo + SOC in the primary efficacy cohort comprised of patients who meet enrollment criteria and have been on mechanical ventilation for <8 days (including zero days for those not on mechanical ventilation). The total number of
participants may expand to 165 patients (110 drug/55 placebo) if there are acceptable efficacy and safety profiles at the interim analyses. The analysis at 21 patients will be

unblinded so this cohort will not be part of the final analysis but will be included in a supportive analysis since results remain confidential. Thus, the sample size for analysis purposes well
be 144 patients for the primary analysis and 165 patients for the supportive analysis.

	8.5	 RLF-100 Treatment Protocol 



Figure 2 shows a graphical flow chart of the RLF100-001 protocol study design. 

Note: If a determination is made to slow down the infusion rate by 50% - the next infusion would still be applied at the next 24-hour period. (E.g. if infusion was started at 8:00 AM and it runs for 18 hours, the next infusion should still take place at 8:00 AM the following day.) If infusion is halted, patient remains in the study.
Physician can dose next day at last well-tolerated dose for a maximum of 3 doses. 
  

	8.6	 Anticipated Risk 



Reported adverse events for intravenous aviptadil include hypotension, tachycardia, facial flushing and watery diarrhea. If this were to
develop, the infusion would be slowed or stopped until resolved. See Flow Chart (Figure 2 above). 
  

	9.	 SELECTION OF SUBJECTS 



 

	9.1	 Study Population

	  	  	Page | 14          















 



 
  


	9.2	 Inclusion Criteria 



All patients entered this trial will have the diagnosis of Critical COVID-19. Subjects will be observed for a 1 to 24-hour period, during which

	10.	 RECRUITMENT, CONSENT & ENROLLMENT 



 

	10.1	 Recruitment & Consent Procedures 



All admissions to the intensive care unit will be screened for fulfillment of inclusion criteria by the Principal Investigator. Patients are
inherently unable to give consent in this setting. The PI or PI’s designee will seek consent from the patient’s responsible party, after explaining the procedure and consent form, approved by all participating sites. It should be noted
that one feature of the COVID-19 pandemic is that non-patients are barred from hospital premises. Therefore, informed consent from responsible parties will generally be obtained telephonically and signature will be obtained via an SMS text message
or otherwise compliant consent systems (e.g. REDCAP). Consent will be documented by a witnessed, consent form, to be kept on file together with telephonic signature. This does not preclude a site from obtaining consent via paper, if such
arrangements can be made, e.g. fax. Should the patient regain ability to consent, consent will be sought accordingly. 
  

	10.2	 Obtaining Informed Consent 



IRB-approved written informed consent forms (ICF) will be obtained from the responsible party of all subjects before any protocol-specified
procedures are carried out. For entry into the study, all inclusion criteria must be met, and none of the exclusion criteria can be met. All signed ICF forms will be logged and kept in locked research cabinets or other restricted electronic system
under the supervision of the local Site PI and available for audit upon request.

	10.3	 Protecting Confidentiality 



Any information obtained in this study will be treated as confidential and will be safeguarded. The data will be coded and kept in a secure
location. When published, the results of the study will be in a form that does not identify any of the patients. In compliance with federal regulations, the records of the study will be available to representatives of the Food and Drug
Administration. 
  

	10.4	 HIPAA Compliance 



The study will be compliant with the Health Insurance Portability and Accountability Act (HIPAA), which protects the privacy and security of
healthcare information. All personal identifying information (PII) will be securely stored and only accessible to healthcare providers and authorized personnel only. 
  

	10.5	 Standard of Care Support 



Supportive treatment in the ICU, including antibiotics, oxygen, mechanical ventilation, blood pressure-supporting medications, and all other
standard of care interventions as needed, will be continued, regardless of participation in the study. 
  

	10.6	 Population Bias 



For unknown reasons, males are affected by severe COVID-19 symptoms twice (2X) as often as are females. It is likely that the enrollment in
this trial will be consistent with that gender difference. There is no evidence to suggest that RLF-100 will be differently tolerated based on race. 
  

	10.7	 Enrollment 



The total number of participants in the primary cohort (mechanical ventilation at enrollment <8 days) will be 144 patients (96 drug/48
placebo). A safety analysis will be conducted by the independent DSMB based on unblinded, unmasked data upon completion of 7-day data collection in 30 patients. DSMB meeting minutes will be recorded and provided to FDA. If the decision is made to
continue the study beyond 30 patients, the next interim analysis will be performed once 81 subjects complete the Day 28 evaluation for a safety and futility determination. Based on the results of this second determination, the study may continue
enrollment to 144 subjects. 
 An additional exploratory cohort of 30 patients (20 drug/10 placebo) will be enrolled at selected study sites
to include patients who have had between 8 – 21 days of exposure to mechanical ventilation. The DSMB will perform an efficacy and futility analysis when approximately 81 patients have completed 28 days of follow up. 

If the two-sided p-value at the time of the interim analysis is
0.01 in favor of efficacy, then the study will stop for superiority. If the conditional power, under the alternative hypothesis is less than 10%, then the study will stop for futility.



 , where t = 81/144 and p is the current one-sided p-value. The one-sided p-value to stop if the interim analysis occurs at exactly 81 patients will be 0.5949. This stop is non-binding and the DSMB will have the ability to continue if they see a
positive signal in a secondary endpoint. The final p-value for efficacy will be adjusting to account for the efficacy evaluation, using the method of Schoenfeld. If the analysis occurs at exactly 81 patients,
that two-sided p-value would be 0.045955. 
 The sample size
calculation (See Section 12.2 below) of 144 subjects (2:1 allocation favoring the RLF-100 group) is required to detect a 25% absolute increase in the composite success percent for the RLF-100 group (assuming 50% success) and the Standard of
Care Group (assuming 25% success) with 83% power and two-sided 5% Type 1 error accounting for the group sequential design using the Schoenfeld method. 

  

			
	  	  	Page | 16          















 



 
  


	10.8	 Randomization Procedures 



Randomization will be on a 2:1 basis with a random block size of 3 or 6; in the event of multiple sites, a centralized randomization will be
used. Subjects will be stratified according to RDR (<200 mmHg, >200 mmHg) and previous anti-viral therapy for COVID-19 (none, any). 

Using this method, even if site personnel believe they can tell the difference between clinical reaction to RLF-100 vs. placebo, they have no
possibility to guess what the next allocation will be. 
  

	10.9	 Procedure for Maintaining the Blind 



Investigational drug will be delivered in identical infusion syringes, labeled by the hospital research pharmacist who is the only unblinded
member of the study site. ICU personnel are entirely blinded, as are patients. Even in the event of unintentional unblinding because of differential efficacy of drug and placebo, the randomization scheme prevents staff from knowing the next
treatment assignment. Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff. 
  

	11.	 TREATMENT OF SUBJECTS 



 

	11.1	 Maximal Standard of Care 



All patients entered in the trial receive Maximal Standard of Care treatment and support, including fluids, antibiotics, vasoactive agents,
non-invasive or mechanical ventilation, hemodialysis, surgery and other supportive measures, as indicated, except for extra-corporeal membrane oxygenation (ECMO). The need for ECMO will be considered a treatment failure on the basis that the lung
has been deemed incapable of supporting adequate metabolic function. Decisions regarding the use of intravenous fluids, cardiovascular and respiratory support, and surgical intervention are made by each patient’s attending physician and are not
dictated by the study protocol. At the completion of the three 12-hour infusions, patients are followed up for the 28 days or until discharged from the hospital, whichever comes sooner. An attempt will be made to follow all patients for 28 days even
after discharge, but it will not be practical during the Corona Pandemic either to bring patients back for post-discharge visits or to make home visits. Death while on life support vs. death following discharge from mechanical ventilation will be
tracked separately. Discharge from mechanical ventilation means that the treating physicians have deemed the patient capable of breathing without the need for mechanical ventilation. A death that occurs because life support has been withdrawn in the
absence of this determination will be recorded as death while on life support. 
  

	11.2	 Proper Standard of Care (SOC) Management Principles 



Management principles are similar despite different etiologies. Oxygenation must be maintained, and the underlying cause of acute lung injury
corrected. Meticulous attention is necessary to prevent nutritional depletion, O2 toxicity, superinfection, barotrauma, and renal failure, which may be worsened by intravascular volume depletion. While the diagnosis is being considered,
life-threatening hypoxemia must be treated with a high FiO2 and monitored with repeated arterial blood gases or noninvasive oximetry. Prompt endotracheal intubation with mechanical ventilation and PEEP may be needed to deliver O2 if hypoxemia is
refractory to O2 inhalation by face mask or nasal cannula. Despite the presence of alveolar edema, IV fluids should be given if needed to restore peripheral perfusion, urine output, and BP. Monitoring vascular volume is crucial because both
hypovolemia and overhydration are deleterious. Physical findings and central venous pressure may be misleading in critically ill patients undergoing mechanical ventilation, and if severe hypoxemia persists, if skin perfusion is poor, if mentation is
impaired, or if urinary output decreases (< 0.5 mL/kg/h), a reliable index of intravascular volume is needed immediately. 
 ECMO is a
lifesaving modality that may be used when mechanical ventilation is unable to support life. However, the availability of ECMO is limited and decisions to allocate ECMO resources to patients are likely to be based on broader triage concerns.
Therefore, ECMO is not considered part of SOC for the purposes of this study and the decision to escalate care to ECMO will be considered a treatment failure for the purpose of this study on the grounds that it signifies a determination that the
lung is unable to support life even with mechanical ventilation.

	11.3	 Placebo 



A normal saline placebo will be supplied by the hospital pharmacy in a labeled container indistinguishable from active drug. 

 

	11.4	 Dosing Regimen 



The escalating dosing regimen for RLF-100 is shown in Figure 2. Each infusion is planned for 12 hours duration, however, the infusion (either
drug or placebo) may be slowed by up to 50% (for an 18-hour total infusion time) at the discretion of the site personnel if side effects cannot be managed to a clinically-acceptable level by the institution’s ICU protocol or SOC. Monitoring of
vital signs and other safety measurements will be ongoing and decisions relating to dose-reduction or cessation will be based on the evaluation of these parameters. 
  

	11.5	 Potential Side Effects of Drug Therapy 



Signs and symptoms to look for: facial flushing, tachycardia, hypotension, diarrhea. These will be monitored for the duration of the infusion,
and for 12 h afterward, by blood pressure and heart telemetry measurements and patient observation. One identified side-effect of Aviptadil infusion is watery diarrhea. As noted above, non-bloody watery diarrhea > 3x/day requiring additional
fluids and electrolyte supplementation is an enrollment exclusion. If watery diarrhea is observed during infusion, the infusion rate should be first reduced by 50% to relieve symptoms. If symptoms persist cease IV infusion. 

 

	12.	 ASSESSMENT OF SAFETY 



 

	12.1	 Serious Adverse Events 



Measurement of serious adverse events (SAE) will be the basis for assessing safety of RLF-100. All SAE’s will be recoded on an IRB
approved SAE Report Form. The SAE Report Form will include the exact nature of the event and the circumstances of the subject at the time of the event, in addition to the usual information required to document AEs or SAEs. Data on all the above will
be collected on separate eCRF pages. The latest version of the AE dictionary, MedDRA, will be used for the classification and analysis of AEs entered in the study database. For regulatory reporting, SAEs will be coded using MedDRA. 

 

	12.2	 Definition of Adverse Events 



An adverse event (AE) is any untoward medical occurrence in a clinical study subject administered a medicinal (investigational or
non-investigational) product. An AE does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the
use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product. (Definition per ICH). AEs will be classified as drug-related, possibly drug-related, or
non-drug related by the study safety monitor. 
  

	12.3	 Definition of a Serious Adverse Event 



The following criteria define a Serious Adverse Event: 
  

	 	1)	 Death 


  

	 	2)	 Life-threatening event 



 

	 	3)	 Persistent or significant disability/incapacity 



If a serious and unexpected AE occurs for which there is evidence suggesting a causal relationship between the study drug and the event (e.g.,
death from anaphylaxis), the event must be reported as a serious and unexpected suspected adverse reaction even if it is a component of the study endpoint (e.g., all-cause mortality). In addition, the following variables will be collected for SAEs:

  

	 	•	 	 Date AE met criteria for SAE 



  

			
	  	  	Page | 18          















 



 
  


	 	•	 	 Date investigator became aware of SAE 



 

	 	•	 	 Explanation of seriousness of this AE 



 

	 	•	 	 Date of hospitalization 



 

	 	•	 	 Date of discharge 


  

	 	•	 	 Probable cause of death 



 

	 	•	 	 Date of death 


  

	 	•	 	 Autopsy performed 


  

	 	•	 	 Causality assessment in relation to study procedure(s) 



 

	 	•	 	 Causality assessment in relation to study drug 



 

	 	•	 	 Causality assessment in relation to other medication 



 

	 	•	 	 Description of AE 


  

	12.4	 Relationship to Study Drugs 



Adverse events and SAEs will be collected from the time of signature of informed consent throughout the treatment period. The investigator will
assess the causal relationship (i.e., the relationship to study treatment) between the investigational product and the AEs and answer “yes” or “no” to the question “Do you consider that there is a reasonable possibility that
the event may have been caused by the investigational product?”. For SAEs, causal relationship will also be assessed. 
  

	12.5	 Recording of Adverse Events 



Abnormal and clinically significant lab values will be reported as AEs if they fulfill any of the SAE criteria or are the reason for
discontinuation of treatment with the study drug. The principal investigator and the study biostatistician will establish the rules for what will constitute abnormal and clinically significant lab values based on established site-specific lab normal
ranges. Adverse events, including abnormal lab values (clinically significant and clinically non-significant), will be review monthly for trends by the principal investigator and the medical monitor. Should any abnormal lab values exceed acceptable
rates, the FDA will be notified within regulatory timelines. Wherever possible, the reporting investigator will use the clinical, rather than the laboratory term (e.g., anemia versus low hemoglobin value). 

 

	12.6	 Reporting of Adverse Events 



All relevant AEs and special reporting situations, whether serious or non-serious, will be reported from the time a signed and dated Informed
Consent Form (ICF) is obtained until completion of the subject’s last study-related procedure. All events that meet the definition of a SAE will be reported as SAEs, regardless of whether they are protocol-specific assessments. All AEs,
regardless of seriousness, severity, or presumed relationship to study drug, must be recorded using medical terminology in the source document and the eCRF. Whenever possible, diagnoses will be given when signs and symptoms are due to a common
etiology. The sponsor assumes responsibility for appropriate reporting of AEs to the regulatory authorities. 
  

	12.7	 Reporting of Serious Adverse Events 



Reportable SAEs will be sent to the FDA by the sponsor. When a SAE is discovered, it will be reported immediately (within 24 business hours) to
the Medical Monitor. Serious adverse events will be reported within 24 business hours of the site’s knowledge of the event to the IRB, Sponsor, Medical Monitor, and study site investigators. 

 

	13.	 ASSESSMENT OF EFFICACY 



 

	13.1	 Data Collection 



Data will be collected via the electronic medical record (EMR) or other hospital information system and ICU telemetry systems. Once collected,
data will be transferred by study personnel to the Target Health 

  

			
	  	  	Page | 19          















 



 
  

 electronic data capture system, which has been audited by FDA in connection with multiple
drug approvals. GCP will be observed throughout, using the quality system in place at Target Health, LLC. Extensive data not already defined in this protocol will be available for analysis via the EMR and telemetry systems. 

 

	13.2	 Maintenance of Blinding 



Investigational drug will be delivered in infusion syringes, labeled by the hospital research pharmacist who is the only unblinded member of
the study site. ICU personnel are entirely masked as to treatment assignment, as are patients. Even in the event of unintentional blinding because of differential efficacy of drug and placebo, the randomization scheme prevents staff from knowing the
next treatment assignment. Moreover, the primary and declared secondary endpoints are not subject to interpretation by ICU staff. 
  

	13.3	 Primary Efficacy Endpoint 



The composite primary endpoint is consistent with the original stated objective of the study and informed by recent FDA input (Reference ID:
4613030 NeuroRx, Inc.) in which FDA recommended proportion of patients alive and free of respiratory failure at day 28. The endpoint is further informed by recent FDA guidance not released at the time of study inception.1 
  

	 	•	 	 Component 1: Resolution of respiratory failure by Day 10, and 



 

	 	•	 	 Component 2: Alive at Day 28 



The best estimate for the composite endpoint success rate is 50% for the drug group and 25% for the placebo group. This preserves the
hypotheses numbers to be tested relative to the original protocol. 
  

	13.4	 Key Secondary Endpoint 



In the findings of the study’s Data Monitoring committee held July 14, 2020, the DMC counseled the use of a primary endpoint that would
measure the difference in area under the curve, thereby using “all the data” available to establish a difference between drug and placebo. Sponsor explained Division’s preference for fixed endpoints and DMC suggested that the
lifetable analysis of time to resolution of respiratory failure be included as a key secondary endpoint. 
  

	13.5	 Assessments of Endpoints 



Composite Endpoint 
 The composite endpoint requires each
of the following to be met: 
  

	 	•	 	 Resolution of respiratory failure (no mechanical or non-mechanical ventilation or high-flow nasal O2) by Day 10.



  

	 	•	 	 Alive Day 28: Patient death is defined as asystole. Data will be collected on whether the death occurred after
withdrawal of care and, if so, the reason for withdrawal of care. Patient death is most likely to occur where the patient was hospitalized. Data will be collected on whether the death occurred after withdrawal of care and, if so, the care withdrawal
reason. 


 Index of Respiratory Distress 

The PaO2/FiO2 ratio shall be calculated from the continual telemetry data obtained from the ICU information system and arterial blood gas (ABG) for patients
while on mechanical ventilation. This variable is not useful after O2 on mechanical ventilation has been reduced because the ratio is reduced even though oxygenation is already improving. In the absence of an arterial line, ABG’s will be
collected only when medically indicated.

 Oxygenation Index 

The Oxygenation index is defined as: 
  

 
 



 
 Inflammatory Markers 

TNFα and other cytokine studies will be performed by the central lab. Note that these are not declared efficacy or safety endpoints 

NIAID 8-point scale 
 The NIAID 8-point scale will be used
as a measure of recovery from Critical COVID-19. 
 Improvement in Chest x-ray 

Chest x-ray images will be collected (1) pre-treatment, (2) 48-96 hours post start of infusion, (3) 1 week ±2 days post start of infusion, and
(4) two weeks ± 2 days post start of infusion, provided the patient is still hospitalized. All x-rays will be read by a blinded radiologist panel and scored according to the Rapid Assessment of Lung Edema (RALE) score (Warren 2017). 

Clinical decision to terminate mechanical ventilation 

Study research personnel will collect all available data regarding the clinical decision-making that guides removal mechanical ventilation in relation to
clinical deterioration or lack of clinical response (e.g. change in status to comfort measures, poor prognosis for recovery, allocation of resources in a pandemic setting, etc.). 

Additional data to be collected 
 Because of the unique
nature of this study and the circumstances under which it is being conducted, at FDA’s request, sponsor will collect all data regarding the use of experimental therapeutic agents (e.g. hydroxychloroquine, IL-6 inhibitors, and other topics of
interest) and deliver those data to FDA for further analysis. Sponsor will make this analysis data set available to the broader scientific community as well. NIAID Scores will also be collected daily through hospital discharge and weekly through Day
28. In addition, time to resolution of respiratory failure, time in ICU, time on mechanical ventilation, time to extubation, time to discharge, multi-organ failure-free days, and inflammatory markers will be collected. 

 

	14.	 STATISTICAL ANALYSIS 



 

	14.1	 Statistical Design and Analyses 



All analyses will be pre-specified in a Statistical Analysis Plan to be finalized with FDA prior to database lock. 

A group sequential design will be employed with one interim analyses for futility and efficacy (n=81). An unblinded analysis will also occur 21
patients for possible study redesign. These 21 patients will not be part of the primary analysis but will be included in a confirmatory analysis since their data were kept confidential. 

All calculations will be performed using SAS statistical software, version 9.3 or later, and StatXact, version 10 or later. All efficacy and
safety data will be displayed in tables and listings separately for each treatment group. Post-Text TLFs will be provided in collated electronic MS Word .rtf files (i.e. table columns and rows appear in MS Word Table format). 

The statistical analyses of the study will be conducted in a GCP environment (ICH E6). 

All patient data will be collected via the electronic medical record and in-house ICU telemetry systems. Dedicated research personnel will
extract data to a de-identified study database for statistical analysis. 
  

	14.2	 Sample Size Calculation 



The sample size calculation of 144 subjects (2:1 allocation favoring the RLF-100 group) is required to


  

			
	  	  	Page | 21          















 



 
  

 detect a 25% absolute increase in the composite success percent for the RLF-100 group
(assuming 50% success) and the SOC group (assuming 25% success) with 83% power and two-sided 5% Type 1 error accounting for the group sequential design using the method in Schoenfeld. 

 

	14.3	 Study Populations 



The intent-to-treat (ITT) population will be based on all randomized patients receiving any study treatment. ITT will be analyzed as
randomized. 
 The safety population will be based on all randomized patients receiving any study treatment. Safety will be analyzed as
treated. 
 The modified intent-to-treat (mITT) population will exclude untreated patients as well as ineligible patients; this will be the
primary efficacy population. 
 The per protocol (PP) population will further exclude patients with major protocol deviations inclusive of,
but not limited to, going on another therapy which would have made them ineligible for the study as well as those with a major protocol deviation as judged by an independent Biostatistics Dara Review Meeting (BDRM). 

 

	14.4	 Statistical Methods 



Continuous variables, e.g., blood pressure, respiratory rate, tidal volume, organ function measurements will be summarized by mean ±
standard deviation, median, and range. Categorical variables, e.g., lung injury score, chest X-ray findings, will be summarized by frequency and corresponding % incidence. 

Evaluation of the primary endpoint (composite) will be analyzed by a pre-defined logistic regression model to include age (<65,
>65 years), baseline NIAID score (2, >2), RDR (<200 mmHg, >200 mmHg), previous anti-viral therapy for COVID-19 (none, any). and treatment as covariates; the method of Firth will be used to estimate unbiased treatment effects while
controlling for these four baseline covariates. Ordinal and continuous outcomes will be assessed by mixed model repeated measures (MMRM) through Day 28. Maximal signal is expected by 10 days. The primary analysis will be based on the modified
intent-to-treat (mITT) population. A Biostatistics Data Review Meeting will be conducted at study completion to determine final mITT population membership. 

Two pre-planned interim analyses will be conducted (n=30 for safety, n=81 for safety and futility). Should enrollment be increased to 144,
there will be 83% power to assess the primary endpoint Evaluation of the secondary endpoint, RCR, will be conducted by a mixed model repeated measures (MMRM) assuming unstructured covariance symmetry with sensitivity analyses to cover early
withdrawals; in the event that the unstructured covariance structure does not converge, then an autoregressive (1) structure will be tried, and if that does not work, then a Toeplitz structure will be tried. 

Time to event outcomes will be displayed using Kaplan-Meier lifetables to account for censoring in the estimation of the Day 28 outcomes;
Greenwood’s formula will be used to estimate Day 28 all-cause survival; time to event endpoints will be analyzed according to a stratified (RDR [<200 mmHg, >200 mmHg], previous anti-viral therapy for COVID-19 [none, any]) logrank test,
while time to resolution of respiratory failure and survival will also be analyzed using a proportional hazard model with the same four pre-defined covariates as for the primary efficacy endpoint; SAS PROC PHREG will be used to estimate unbiased
treatment effects while controlling for the above four baseline covariates. 
 For other endpoints, MMRM will be used based on available data
as well as imputing outcomes for subjects after death or worsening condition, e.g. ECMO or death, using last observation carried forward (LOCF). Time to (alive) hospital discharge will be displayed descriptively. 

  

			
	  	  	Page | 22          















 



 
  

 The NIAID score will be displayed over time. The area under the curve will also be calculated
and compared using an unpaired t-test. Patients dying prior to Day 28 will be carried through Day 28 as being dead. 
  

	14.5	 Interim Analysis, Futility/Safety 



Upon completion of observations through Day 7 for the first 30 subjects, an unmasked/unblinded analysis will be performed for the independent
DSMB in order to assess safety. Safety determinations will entail a review of AEs and SAEs by the independent Data Safety and Monitoring Board in consultation with FDA. Based on this evaluation, the DSMB/FDA will decide whether to permit adding
additional study sites and enrolling additional patients. 
 The second interim analysis will be assessed for safety, futility, and efficacy
once 81 subjects complete Day 14. Futility will be defined as no composite endpoint success percent advantage of RLF-100 over placebo when a 25% absolute advantage is expected. The study may be stopped for safety or futility (seeing a conditional
power ~10%). The study may be stopped for superiority (two-sided p=0.01). 
 Secondary efficacy analyses will include the overall
distribution of time to resolution of respiratory failure. 
 The DSMB will advise regarding the favorable benefit/risk associated with early
efficacy with safety. 
  

	15.	 HYPOTHESIS TESTS 



 

	15.1	 Treatment Comparisons 



Hierarchical testing will be used to preserve the Type 1 error associated with multiple endpoints (per FDA guidance). The testing order follows
with two-sided p=0.046 required to continue testing for label claims: 
 Primary Outcome Measure:  

Composite endpoint requiring each of the following to be met: 
  

	 	1)	 Resolution of respiratory failure by Day 10, and 



 

	 	2)	 Alive Day 28. 



Key Secondary Measure: 
  

	 	3)	 Time to resolution of respiratory failure, expect to see advantage by Day 10 



Secondary Outcome Measures: 
  

	 	4)	 Respiratory Distress while on mechanical ventilation: 



	 	            Blood	 PaO2/FiO2 ratio [Time Frame: enrollment through extubation] 



 

	 	5)	 Oxygenation Index 


  

	 	6)	 Improvement in chest x-ray 



 

	 	7)	 NIAID Ordinal Scale for Clinical Improvement 



 

	 	8)	 NIAID Area under the curve (AUC) 



Other Outcome Measures: 
  

	 	9)	 Survival lifetable 


  

	 	10)	 Time in ICU 


  

	 	11)	 Time on mechanical ventilation (to end of last mechanical ventilation) 



 

	 	12)	 Time on ventilation (to end of last ventilation) 



 

	 	13)	 Time to extubation (to end of last intubation) 



 

	 	14)	 Time to discharge alive (to end of last hospitalization) 



 

	 	15)	 Multi-organ failure free days 



 

	 	16)	 TNFα and other inflammatory markers 



  

			
	  	  	Page | 23          















 



 
  


	15.2	 Primary Hypothesis 



The null hypothesis (H0) is that there is no difference in the composite endpoint
success rate (SR) while the alternative hypothesis (Ha) is that there is a RLF-100 advantage in the composite endpoint success rate: 

H0:
SRRLF-100<SRPLA 

Ha:
SRRLF-100>SRPLA 
 A
25% absolute improvement in the success rate is deemed to be clinically meaningful. A 25% success rate is expected for Placebo + Maximal SOC while a >50% success rate is expected for RLF-100 + Maximal SOC. 

 

	15.3	 Primary Efficacy Endpoint: Composite Success 



The primary outcome measurement is the composite endpoint which is a binary success/fail endpoint where both components must be met to declare
success. Patients must have Day 28 follow-up to be declared a success. 
  

	15.4	 Key Secondary Efficacy Endpoint: Time to Resolution of Respiratory Failure 



Time to resolution of respiratory failure is defined as the latter of going off all ventilation and off high-flow O2. A Kaplan-Meier lifetable will be generated; a stratified logrank test and a proportional hazard model will be run to include the four previously stated endpoint covariates. Resolution will be
considered to be the event. 
  

	15.5	 Secondary Efficacy Endpoint: Blood PaO2/FiO2 Ratio (while on mechanical ventilation)



 Blood PaO2/FiO2 ratio is measured at every 24 hours with additional endpoint determinations through cessation of
mechanical ventilation. Time to normalization will be evaluated; this endpoint will also be analyzed using MMRM. 
  

	15.6	 Secondary Efficacy Endpoint: Oxygenation Index 



The Oxygenation Index is measured at every 24 hours and 28 days post intubation with additional endpoint determinations through cessation of
mechanical ventilation. Time to normalization (last SaO2 value >95%) will be evaluated; this endpoint will also be analyzed using MMRM. 
  

	15.7	 Secondary Efficacy Endpoint: Improvement in Chest x-ray 



The RALES score will be ascertained by a blinded radiologist panel. The percent with improvement in chest x-ray over time will be independently
determined by the panel. Percents improving will be compared using a two-sided Fisher Exact test while the RALES score distribution over time will be evaluated using MMRM. 
  

	15.8	 Secondary Efficacy Endpoint: NIAID 8-point Scale and Area Under the Curve 



The NIAID 8-point scale will be used as a measure of overall recovery from Critical COVID-19. The area under the curve (AUC) will be computed
from all available NIAID data through Day 28 including death; in addition, MMRM will be run for all available NIAID data through Day 28. 

  

			
	  	  	Page | 24          















 



 
  


	15.9	 Secondary Efficacy Endpoint: Survival 



Survival is defined as not having died as ascertained from the medical record. If death occurs post discharge and prior to Day 28, study
personnel will attempt to obtain a death certificate but may not succeed in the current emergency. A Kaplan-Meier lifetable will be generated; a stratified logrank test and a proportional hazard model will be run to include the four previously
stated endpoint covariates. All deaths from any cause are included in the survival analysis; the 28-day all-cause survival will be estimated from the Kaplan-Meier lifetable. 
  

	15.10	 Other Efficacy Endpoints: ICU, Ventilations, Extubation, and Discharge 



Kaplan-Meier lifetables will be generated for each of the time to last ICU release, time to last going off ventilation and mechanical
ventilation, and time to extubation. Time to alive discharge will be a descriptive statistic (mean, SD, range) for the subset alive at discharge. 
  

	15.11	 Other Efficacy Endpoint: Multi-system Organ Failure 



The days free of multi-system organ failure will be computed; organs include sepsis, blood, brain, heart, liver, and kidneys. Written
guidelines for specific organ failure will be separately generated prior to database lock. The days free of multi-system organ failure will be assessed using the Schoenfeld method. 

 

	15.12	 Laboratory Efficacy Endpoints: Inflammatory Markers 



The secondary laboratory outcome measures are TNFα, IL6, and other inflammatory markers as measured in the central laboratory. 

 

	15.13	 Overall Safety Endpoints 



All safety results will be presented separately for each treatment group. Safety endpoints will include adverse events (AE), vital signs (VS),
and relevant clinical chemistries and hematology parameters. Safety and tolerability will be assessed using two-sided Fisher Exact tests to compare RLF-100 vs. Placebo. Mean changes from randomization baseline will be displayed for each serum
chemistry and hematology parameter as well as the shift; unpaired t-tests will be used to compare RLF -100 vs. Placebo at designated study times. In addition, paired t-tests will be performed for the change from randomization baseline within each
study treatment group. 
  

	16.	 SOURCE DATA & DOCUMENTS 



 

	16.1	 Sources of Research Materials 



The following source data and documents will be collected. All blood samples, except those taken for cytokine and arachidonate metabolite level
monitoring, which would be part of this investigation, would be obtained in the normal course of clinical care of these patients as described above. 
  

	16.2	 Case Report Form 



The Case Report Form (CRF) is an integral part of the study and subsequent reports. The CRF must be used to capture all study data recorded in
the patient’s medical record. The CRF must be kept current to reflect patient status during the study. Only a patient screening and randomization number will be used to identify the patient. 

 

	16.3	 Patient Identification 



Patient name, medical record number, age, gender, height, weight, ethnic background, residence address with zip code will be collected. 

  

			
	  	  	Page | 25          















 



 
  


	16.4	 General Clinical Data 



Primary diagnosis, coexisting diagnoses / conditions, hospital length of stay and outcome will be collected. 

 

	16.5	 Lung Injury / ARDS Data 



PaO2/FiO2 ratio; PEEP/CPAP;
peak, mean & plateau pressures; compliance (dynamic and quasi-static); tidal volume; respiratory rate; minute ventilation, lung injury score, chest X-ray findings will be collected. 

 

	16.6	 Laboratory Data 



Arterial blood pH, PCO2, PO2;
electrolytes (Na, K, Cl, HCO3); renal function (BUN, serum creatinine); glucose, albumin & total plasma proteins; liver function tests; blood cell count; coagulation profile; lactic acid and D-Dimer
will be collected. 
  

	16.7	 Vital Signs, Respiratory and Hemodynamic Data 



Blood pressure (systolic, diastolic, mean), heart rate, respiratory rate, cardiac output/cardiac index, pulmonary artery (PA) wedge pressure,
systolic, diastolic & mean pressures (if PA catheter is in place), right atrial/central venous pressure, systemic and pulmonary vascular resistance, systemic 02 delivery, daily urine output, daily fluid intake will be collected. 

 

	16.8	 Medical Therapy Data 



Antibiotics (type and days of use), fluids, RBC transfusions, vasopressors and inotropes, sedation or analgesia, neuromuscular blockade,
nutritional therapy will be collected. 
 The therapeutic milieu for RLF100-001 – ICU-type settings during the COVID-19 pandemic – requires a thoughtful and practical approach to the capture of concomitant medications in clinical studies. Specifically,
the capture of relevant concomitant medications is required under three circumstances: 
 1. As part of a relevant medical history entry,
where relevant medical history is defined as relating to an inclusion or exclusion criteria; 
 2. As part of an AE entry, for agents
administered in response to the AE; and 
 3. Agents of interest, namely Biotin, IL6, antiviral therapies, steroids, nitric oxide,
epoprostenol (Flolan), pressors (e.g., norepinephrine, epinephrine, Vasopressin), paralytics, anticoagulants, convalescent plasma, and tocilizumab (Actemra) and other immunomodulators. 

Please note there is a unique dedicated CRF page for capturing concomitant use of convalescent plasma – no need for a duplicate entry on a
concomitant medication form. 
 Furthermore, sites will be asked to report unusual circumstances in their ICU that require medical therapy
that can negatively affect the prognosis of a patient, e.g. emergence of treatment resistant bacteria leading to high mortality. 
  

	16.9	 Pharmacokinetic Sampling 



The pharmacokinetics of intravenous Aviptadil are well understood and do not require revalidation in this study. 

 

	16.10	 Blood Sampling 



Blood samples are obtained for biochemical, electrolyte, and hematologic profiles per ICU protocol. Blood samples for cytokine (TNF-alpha, IL-6, which correlate with the inflammatory response and with mortality levels are obtained before, at 2 hours and at 12 hours, and then daily on day 5, day 7 and
day 28 or day of discharge. Leukotrine E4 (urine) and Plasma VIP levels are checked at the same intervals to ensure the delivery of the peptide into the circulation. Plasma is separated within 30 min, frozen and stored at -70 C until the assays are performed, by specific radio-immunoassays or ELISA. Additionally, D-Dimer may be added when available.

	17.	 STUDY MONITORING 



 

	17.1	 Study Monitoring 



The study sites have been evaluated by the sponsor in conjunction with the CRO to determine suitability for the proposed study. Information
reviewed included, but was not be limited to, facility details and site capabilities, past performance in similar studies, investigator, and staff experience, ongoing studies at the site, projected enrollment in this study, and FDA or other agency
audit findings. Prior to subject enrollment, a virtual study initiation visit will be completed by video conference to ensure the following: IRB approval has been obtained and documented prior to subject screening, the investigators and study
personnel are appropriately trained and clearly understand the study, the investigators and study personnel accept the obligations incurred in undertaking this clinical investigation. 

Periodic remote monitoring visits will be made in accordance with the approved monitoring plan at all active study sites throughout the
clinical study to assure that the investigator obligations are fulfilled, and all applicable regulations and guidelines are being followed. These visits will assure that the facilities are still compliant with study requirements, the protocol and
investigational plan are being followed, the IRB has been notified of approved protocol changes as required, complete records are being maintained, appropriate and timely reports have been made to the sponsor and the IRB, and the site Investigator
is executing all agreed activities. Given the public health crisis, these visits will done via virtual means and specific monitoring arrangements with each site. 
  

	17.2	 Data Safety and Monitoring 



All results from this study will be reviewed by a Data Safety and Monitoring Committee, chaired by Prof. Alfred Sommer, MD, MHS, Dean Emeritus
of the Bloomberg School of Public Health. Membership of this committee will include: a clinician specialist in Critical Care Medicine, a biostatistician, and a lay patient advocate. The committee will critique the progress of the trial, carefully
examine any incidents of adverse reactions, and may suggest appropriate revisions in the protocol. DSMB functions include, among others, ongoing assessment of masked data to determine whether any of the treatment arms show increased risk for AEs.


  

			
	  	  	Page | 27          















 



 
  


	17.3	 Medical Monitor 



The Medical Monitor will review and approve the eligibility of all screened subjects, review all AEs, assess the benefits and risks of
protocols on an ongoing basis, and work in collaboration with the IRB and DMC to identify safety signals and trends. In addition, the Medical Monitor will be available for site questions regarding inclusion/exclusion criteria, protocol conduct, and
safety. Trained and qualified physicians will be available to provide coverage during times when the medical monitor is unavailable. Sites will be provided with the Medical Monitor’s cell phone number for emergency situations. Otherwise, sites
are instructed to contact the Medical Monitor through email. All critical conversations with sites will be documented by the Medical Monitor and reviewed periodically by the sponsor. Each month the Medical Monitor will receive a listing of protocol
violations for review and identification of possible trends. 
  

	17.4	 Audits and Inspections 



Contracts with study sites will specify that sponsor or its representatives will have direct access to source data and documents for study
monitoring, which may be done through virtual/electronic means. Additionally, the IRB and FDA may review source data following appropriate guidelines for this process. 
  

	17.5	 Institutional Review Board 



The study protocol and any amendments will be reviewed by the Advarra Institutional Review Board (IRB). The IRB will review the informed
consent form, their updates (if any), and any written materials given to the participants. IRB approval will be obtained and documented prior to subject enrollment and screening. Before study initiation, the investigator must have written and dated
approval from the IRB for the protocol, consent form, subject recruitment materials/process (e.g., advertisements), and any other written information to be provided to subjects. The investigators will provide the IRB with reports, updates, and other
information (e.g., Safety Updates, Amendments, and Administrative Letters) according to regulatory requirements and Institution procedures. A detailed list of required regulatory documents, to be submitted to the sponsor, will be sent upon final
approval of the protocol. 
  

	18.	 ETHICAL CONSIDERATIONS 



 

	18.1	 Ethical Considerations 



Anticipated benefits to participants and others: There are at present no satisfactory specific treatments for ARDS, or multiple
organ dysfunction. Based on a large body of experimental work, there is reason to expect that RLF-100 (aviptadil) may prove effective in increasing survival rates in
COVID-19 patients with ARDS, as well as increasing blood 02, reducing organ failure and reducing cytokine cascades. 

Anticipated risks to participants and others: The only anticipated risks are due to the side-effects noted above of hypotension,
tachycardia and watery diarrhea. Aviptadil has been evaluated in 4 species toxicology studies and the LD50 is more than 50x the exposure contemplated in this trial. 
  

	18.2	 Ethical Conduct of the Study 



This study will be conducted in accordance with the ethical principles that have their origins in the Declaration of Helsinki, in compliance
with the approved protocol, GCP, and applicable regulatory requirements. 
  

	18.3	 Informed Consent 



The patient’s legally authorized representative (LAR) must be capable of understanding the nature of this study and its potential risks,
discomforts, and benefits. Study physicians or their delegate will obtain consent after they have fully explained the study purpose and procedures, and the LAR has demonstrated an understanding of the protocol, willingness to participate, and
competency to consent. The investigator or their delegate must ensure that subjects are clearly and fully informed about the purpose, potential risks, 

  

			
	  	  	Page | 28          















 



 
  

 and other critical issues regarding clinical trials in which they volunteer to participate.
Preparation of the site-specific consent form is the responsibility of the site Principal investigator and must include all elements required by CFR 21 Part 50.25 and the IRB. 

 

	19.	 DATA HANDLING & RECORD KEEPING 



 

	19.1	 Data Capture 



An investigator is required to prepare and maintain adequate and accurate case histories designed to record all observations and other data
pertinent to the investigation on everyone treated with the investigational product or entered as a control in the investigation. 
  

	19.2	 Data Collection 



No manual data collection is anticipated in the ICU. Data will be extracted from the EMR and other sources by hospital clinical research staff
in a HIPAA-compliant, de-identified manner and transferred to the study database. 
  

	19.3	 Retention of Records 



The investigator must retain investigational product disposition records, case report forms, and source documents for the maximum period
required by applicable regulations and guidelines, or in accordance with institution procedures, and at least for 10 years. This is study practice in the study sites. 
  

	19.4	 Use of Information and Publication Policy 



All publications will be reviewed by the sponsor for accuracy before submission to peer-reviewed journals or scientific meetings. Abstracts
will be submitted for review at least 10 days before submission, and publications should be submitted for review at least 30 days before submission. The study will be posted to Clinicaltrials.gov, and results will be reported in accordance with
Clinicaltrials.gov guidelines.
