Saline solution/heparin-saline continuous ush set
Rotating Hemostasis Valve (RHV)
Infusion stand
Femoral arterial lock
PREPARATION AND PROCEDURE
Preparation
1. Administer anti-coagulation and anti-platelet medications per standard institutional guidelines.
2. Aided by angiographic radiography, determine the location and size of the area to be revascularized.
3. Select a Solitaire™ Platinum Revascularization Device per Table 1.
4. To achieve optimal performance of the Solitaire™ Platinum Revascularization Device and to reduce the risk of thromboembolic complications, maintain continuous ushing action between a) the femoral arterial sheath and the guide catheter, b) the microcatheter and the guide catheter and c) the microcatheter and the push wire and the Solitaire™ Platinum Revascularization Device. Check all connections to make sure that during the continuous ush no air enters the guide catheter or the microcatheter.
5. Position a suitable guide catheter as close to thrombus site as possible employing a standard method. The guide catheter should be appropriately sized to retrieve clot if so desired in subsequent steps. Connect a RHV to the tting of the guide catheter, and then connect a tube to the continuous ush.
6. With the aid of Table 1, select a microcatheter suitable for advancing the Solitaire™ Platinum Revascularization Device.
7. Connect a second RHV to the tting of the microcatheter and then connect a tube to the continuous ush.
8. Set the ush rate per standard institutional guidelines.
9. With the aid of a suitable guide wire, advance the microcatheter until the end of the microcatheter is positioned distal to the thrombus so that the usable length portion of the Solitaire™ Platinum Revascularization Device will extend past each side of the thrombus in the vessel when fully deployed. Tighten the RHV around the microcatheter.
Delivering the Solitaire™ Platinum Revascularization Device
10. Insert the distal end of the introducer sheath partially into the RHV connected to the microcatheter. Tighten the RHV and verify that uid exits the proximal end of the introducer sheath.
11. Loosen the RHV and advance the introducer sheath until it is rmly seated in the hub of the microcatheter. Tighten the RHV around the introducer sheath to prevent back ow of blood, but not so tight as to damage the Solitaire™ Platinum Revascularization Device during its introduction into the microcatheter. Conrm that there are no air bubbles trapped anywhere in the system.
12. Transfer the Solitaire™ Platinum Revascularization Device into the microcatheter by advancing the push wire in a smooth, continuous manner. Once the exible portion of the push wire has entered the microcatheter shaft, loosen the RHV and remove the introducer sheath over the proximal end of the push wire. Once completed, tighten the RHV around the push wire. Leaving the introducer sheath in place will interrupt normal infusion of ushing solution and allow back ow of blood into the microcatheter.
13. Visually verify that the ushing solution is infusing normally. Once conrmed, loosen the RHV to advance the push wire.
14. Once the Solitaire™ Platinum Revascularization Device has been advanced to the uorosafe marker band begin uoroscopic imaging. With the aid of uoroscopic monitoring, carefully advance the Solitaire™ Platinum Revascularization Device until its distal markers line up at the end of the microcatheter. The Solitaire™ Platinum Revascularization Device should be positioned such that the usable length portion of the device will extend past each side of the thrombus in the vessel when the device is fully deployed.
WARNING  ALL INDICATIONS
If excessive resistance is encountered during the delivery of the Solitaire™ Platinum Revascularization Device, discontinue the delivery and identify the cause of the resistance. Advancement of the Solitaire™ Platinum Revascularizaton Device against resistance may result in device damage and/or patient injury.
Deploying the Solitaire™ Platinum Revascularization Device
15. Loosen the RHV around the microcatheter. To deploy the Solitaire™ Platinum Revascularization Device, x the push wire to maintain the position of the device while carefully withdrawing the microcatheter in the proximal direction.
Figure 2:
Solitaire™ Platinum Revascularization Device Deployment
16. Retract the microcatheter until it is just proximal to the proximal marker of the Solitaire™ Platinum Revascularization Device. Tighten the RHV to prevent any movement of the push wire. The usable length of the deployed Solitaire™ device should extend past each side of the thrombus.
17. Tighten the RHV around the microcatheter. Angiographically assess the revascularization status of the treated vessel.
Revascularization Device Recovery
18. If using balloon guide catheter, inate guide catheter balloon to occlude vessel as specied in Balloon Guide Catheter labeling.
19. Ensure the proximal marker on the Solitaire™ Platinum Revascularization Device is within the microcatheter as in Figure 3 below. Loosen the RHV around the microcatheter enough for movement while still maintaining a seal.
Figure 3:
Solitaire™ Platinum Revascularization Device Recovery Position

20. To retrieve thrombus, slowly withdraw the microcatheter and the Solitaire™ Platinum Revascularization Device as a unit to the guide catheter tip while applying aspiration to the guide catheter with the aspiration device. Never advance the deployed Solitaire™ Platinum Revascularization Device distally.
NOTE: Ensure microcatheter covers proximal marker.
21. Apply vigorous aspiration to the guide catheter using the aspiration device and recover the Solitaire™ Platinum Revascularization Device and microcatheter inside guide catheter. Continue aspirating guide catheter until the Solitaire™ Platinum Revascularization Device and microcatheter are nearly withdrawn from the guide catheter.
NOTE: If withdrawal into the guide catheter is dicult, deate balloon (if using balloon guide catheter) and then simultaneously withdraw guide catheter, microcatheter and Solitaire™ Platinum Revascularization Device as a unit through the sheath while maintaining aspiration. Remove sheath if necessary.
WARNINGS  ALL INDICATIONS
If excessive resistance is encountered during recovery of the Solitaire™ Platinum Revascularization Device, discontinue the recovery and identify the cause of the resistance.
For vessel safety, do not perform more than three recovery attempts in the same vessel using the Solitaire™ Platinum Revascularization Device.
22. Open the guide catheter RHV to allow the microcatheter and the Solitaire™ Platinum Revascularization Device to exit without resistance. Use care to avoid interaction with the site of the intervention and to prevent air from entering the system.
23. Aspirate the guide catheter to ensure the guide catheter is clear of any thrombus material.
24. Deate guide catheter balloon if using balloon guide catheter.
25. If additional ow restoration attempts are desired with:
a. A new Solitaire™ Platinum Revascularization Device, then:
i. Repeat the steps described above starting with the “Preparation” section.
b. The same Solitaire™ Platinum Revascularization Device, then:
i. Clean the device with saline solution.
NOTE: Do not use solvents or autoclave.
ii. Carefully inspect the device for damage. If there is any damage, do not use the device and use a new
Solitaire™ Platinum Revascularization Device for subsequent ow restoration attempts following the steps described above starting with the “Preparation” section. Use of a damaged device could result in additional device damage or patient injury.
WARNING  ALL INDICATIONS
For device safety, do not use each Solitaire™ Platinum Revascularization Device for more than three ow restoration recoveries.
Solitaire™ Platinum Revascularization Device Re-Sheathing
If resheathing of the Solitaire™ Platinum Revascularization Device is necessary (e.g. repositioning), follow these steps:
WARNING  ALL INDICATIONS
Advancing the microcatheter while the device is engaged in clot may lead to embolization of debris.
Do not advance the microcatheter against any resistance.
Do not reposition more than two times.
1. Loosen the RHV around the microcatheter and around the push wire. With the aid of uoroscopic monitoring, hold the push wire rmly in its position to prevent the Solitaire™ Platinum Revascularization Device from moving.
2. Carefully re-sheath the Solitaire™ Platinum Revascularization Device by advancing the microcatheter over the Solitaire™ Platinum Device until the distal markers of the Solitaire™ Platinum Device line up at the end of the microcatheter as illustrated in Figure 4 below. If significant resistance is encountered during the re-sheathing process, stop immediately and proceed to the section above entitled “Revascularization Device Recovery”.

SAFETY AND EFFECTIVENESS INFORMATION  INDICATION 1
SWIFT PRIME Clinical Study
SWIFT PRIME (Solitaire™ FR or Solitaire™ 2 With the Intention For Thrombectomy as Primary Endovascular Treatment for Acute Ischemic Stroke) is a global, multicenter, two-arm, prospective, randomized, open, blinded endpoint (PROBE) clinical study comparing neurological disability outcomes (dened by mRS) in Acute Ischemic Stroke (AIS) patients who are treated with either IV t-PA alone or IV t-PA in combination with Solitaire™ FR or Solitaire™ 2 mechanical thrombectomy intervention. Subjects receiving IV t-PA within 4.5 hours of symptom onset were randomized 1:1 to mechanical thrombectomy with Solitaire™ within 6 hours of onset, or to continuation with IV t-PA alone. Within this group, the Analysis cohort was dened as those subjects who were administered IV t-PA within 3 hours of symptom onset.

Study Endpoints
The primary eectiveness endpoint of the study is 90-day global disability assessed via the blinded evaluation of modied Rankin Scale (mRS). Secondary clinical ecacy endpoints of the study are:
Death due to any cause at 90 days.
Functional independence as dened by mRS score ≤ 2 at 90 days.
Change in NIHSS score at 27 ± 6 hours post randomization. The secondary technical ecacy endpoints of the study are:
Volume of cerebral infarction as measured by a CT or MRI scan at 27 ± 6 hours post randomization.
Reperfusion measured by reperfusion ratio on CT or MRI scan 27 ± 6 hours post randomization.
Arterial revascularization measured by TICI 2b or 3 following device use.
Correlation of RAPID-assessed core infarct volume with 27 ± 6 hours post randomization stroke infarction in subjects who achieved TICI 2b-3 reperfusion without intracranial hemorrhage.
Results
A total of 196 subjects were randomized into the SWIFT PRIME Study (98 in each group). The SWIFT PRIME study allowed IV t-PA use beyond 3 hours, although IV t-PA is not approved in the United States beyond 3 hours. Patients treated with IV-tPA beyond 3 hours did not factor strongly in the evaluation of the Solitaire™ 2 revascularization device and have been excluded from the analyses. The resulting Analysis Cohort consists of 161 subjects (84 in the IV t-PA plus Solitaire™ group and 77 with IV t-PA only). Additionally, 17 subjects in the IV t-PA plus Solitaire™ group were excluded from the primary and secondary ecacy endpoint analyses. These 17 subjects either received carotid stenting and/or angioplasty or were treated in a manner inconsistent with the Solitaire™ Instructions for Use. Therefore, the primary and secondary ecacy endpoint analyses cohort consists of 144 subjects.
The proportion of patients functionally independent (mRS 0-2) at the 90-day visit was higher in the IV t-PA plus Solitaire™ device group. A summary of the subject disposition is presented below.

Standard summary statistics were calculated for all study variables and subject data were analyzed according to the group to which they were randomized. For continuous variables, statistics included means, standard deviations, medians and ranges. Categorical variables were summarized in frequency distributions.
For the primary ecacy endpoint, statistical signicance was declared using bounds predened in the group sequential analysis plan, which accounts for multiplicity due to interim analyses. Elsewhere, one-sided statistical tests having p-values less than 0.025 were deemed signicant while two-sided tests having p-values less than 0.05 were deemed signicant.
For adverse event reporting, the primary analysis is based on subject counts, not event counts. Both subject counts and event counts are presented in tabular summaries of results.
NOTE: The SFR3-4-20-05, SFR3-4-20-10, SFR3-4-40-10, SFR3-6-20-10, SFR3-6-24-06 and SFR3-6-40-10 models were not evaluated as part of the SWIFT PRIME study.

Reason for Screen Failure Subjects (no.)
Thrombolysis in Cerebral Infarction (TICI) > 1 ow in the intracranial internal carotid artery, M1 segment of the MCA, or carotid terminus conrmed by CT or MR angiography that is accessible to the Solitaire™ FR Device.
MRI- or CT-assessed core infarct lesion greater than 50 cc; severe hypoperfusion lesion (Tmax>10secs lesion greater than 100 cc); and/or Ischemic penumbra < 15 cc and mismatch ratio ≤1.8.
CT showing hypodensity or MRI showing hyperintensity involving greater than 1/3 of the middle cerebral artery (MCA) territory (or in other territories, >100 cc of tissue) on presentation.
NIHSS < 8 or ≥ 30 at the time of randomization 9
CTA or MRA evidence of carotid dissection or complete cervical carotid occlusion. 3
CT or MRI evidence of mass eect or intra-cranial tumor (except small meningioma). 3
Rapid neurological improvement prior to study randomization suggesting resolution of signs/ symptoms of stroke.
Pre-stroke Modied Rankin Score> 1 2
Baseline non-contrast CT or DWI MRI evidence of a moderate/large core dened as extensive early ischemic changes of Alberta Stroke Program Early CT score (ASPECTS) < 6.
Imaging evidence that suggests, in the opinion of the investigator, the subject is not appropriate for mechanical thrombectomy intervention (e.g., inability to navigate to target lesion, moderate/large infarct with poor collateral circulation, etc.).
Previous intracranial hemorrhage, neoplasm, subarachnoid hemorrhage, cerebral aneurysm, or arteriovenous malformation.
CTA or MRA evidence of carotid dissection or complete cervical carotid occlusion requiring stenting at the time of the index procedure (i.e., mechanical thrombectomy).
Subject is unwilling to conduct protocol-required follow-up visits. 1
Age >80 years old 1
Known hereditary or acquired hemorrhagic diathesis, coagulation factor deciency. 1
Contraindication to IV t-PA as per local national guidelines. 1
History of stroke in the past 3 months. 1

SAFETY AND EFFECTIVENESS INFORMATION  INDICATION 2
SWIFT Clinical Study
SWIFT (Solitaire™ With the intention For Thrombectomy study; IDE G090082) is a multicenter, randomized, prospectively controlled study in clot retrieval for patients diagnosed with an acute ischemic stroke. The objective of the study is to demonstrate substantial equivalence of the Solitaire™ FR Revascularization Device with the Concentric Medical Merci™ device. Primary ecacy was demonstrated by arterial recanalization of occluded target vessel measured by Thrombolysis in Myocardial Infarction (TIMI) score of 2 or 3 following the use of the Solitaire™ device without any symptomatic intracranial hemorrhage.
Inclusion Criteria
Subjects were considered eligible for the study if they satised all of the following inclusion criteria:
Subject or subject’s legally authorized representative has signed and dated an Informed Consent Form
Age 22 – 85
Clinical signs consistent with acute ischemic stroke
National Institute of Health Stroke Scale (NIHSS) score of at least 8 and less than 30
Thrombolysis in Myocardial Infarction (TIMI) 0 or TIMI 1 ow in the M1 or M2 of MCA, ICA, basilar or vertebral arteries
conrmed by angiography that is accessible to the Solitaire™ FR device or Concentric Medical’s MERCI device
Subject is able to be treated within 8 hours of stroke symptoms onset with minimum of one deployment of the
Solitaire™ FR device or Concentric Medical’s MERCI device
Subject who is ineligible or failed intravenous tissue plasminogen activator (t-PA) therapy given at local institutions
or within national practice. (NOTE: Failed IV-tPA is dened as subjects with occlusion present 61 minutes or more after start of IV therapy)
Subject is willing to conduct follow-up visits
Exclusion Criteria
Subjects were considered ineligible for study participation if they met any of the following exclusion criteria:
NIHSS score of 30 or greater
Neurological signs that are rapidly improving prior to or at time of treatment
Females who are pregnant or lactating
Known serious sensitivity to radiographic contrast agents
Current participation in another investigational drug or device study
Uncontrolled hypertension dened as systolic blood pressure >185 or diastolic blood pressure >110 that cannot be
controlled except with continuous parenteral antihypertensive medication
Use of warfarin anticoagulation with INR > 3.0
Platelet count < 30,000
Glucose < 50 mg/dl
Arterial tortuosity that would prevent the device from reaching the target vessel
Life expectancy of less than 90 days
Additionally, subjects were also considered ineligible for study participation if they met any of the following imaging
exclusion criteria:
CT or MRI evidence of hemorrhage on presentation
CT showing hypodensity or MR showing hyperintensity involving greater than 1/3 of the middle cerebral artery (MCA) territory (or in other territories, >100 cc of tissue) on presentation
CT or MRI evidence of mass eect or intracranial tumor (except small meningioma)
Angiographic evidence of carotid dissection, complete cervical carotid occlusions, or vasculitis
Study Endpoints
The primary eectiveness endpoint of the study is successful recanalization with no symptomatic hemorrhage (SRNH), dened as achieving TIMI 2 or 3 ow in all treatable vessels without any presence of symptomatic intracranial hemorrhage.
Successful recanalization is dened as achieving TIMI 2 or 3 ow in all treatable vessels.
Successful recanalization of the MCA includes all M1 and M2 segments, internal carotid terminus lesions include the ICA, M1 and both M2 branches, and posterior circulation includes both the vertebral and basilar arteries.
Symptomatic intracranial hemorrhage is dened as any PH1, PH2, RIH, SAH, or IVH associated with a decline in NIHSS ≥ 4 within 24hrs.
Results
Fifty eight (58) randomized Solitaire™ FR Revascularization Device and thirty one (31) roll-in patients were treated with the Solitaire™ FR Revascularization device in the SWIFT study. The median age and NIHSS at the time of treatment were 66 years and 17, respectively. Data from this study demonstrate that the Solitaire™ FR Revascularization Device is non­inferior to the Merci device for arterial recanalization of the occluded target vessel without any presence of symptomatic intracranial hemorrhage. A summary of the subject disposition is presented below.

All subjects who were consented and randomized were included in the intention-to-treat (ITT) population. The ITT population included all subjects with data for a given endpoint; results were assessed according to randomized assignment regardless of the treatment actually received.
The primary ecacy analysis (successful recanalization measured by TIMI ow without symptomatic hemorrhage) was performed using a one-sided test under Blackwelder’s method of testing non-inferiority at the 0.025 level of signicance. The primary safety endpoint of device- and/or procedure related Serious Adverse Events (SAEs) was evaluated descriptively.
NOTE: The SFR3-4-20-05, SFR3-4-20-10, SFR3-4-40-10, SFR3-6-20-10, SFR3-6-24-06 and SFR3-6-40-10 models were not evaluated as part of the SWIFT study.

SAFETY AND EFFECTIVENESS INFORMATION  INDICATION 3
DEFUSE 3 Clinical Study
The Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke (DEFUSE 3) study was a multicenter, randomized, open-label trial, with blinded outcome assessment, of thrombectomy in patients 6 to 16 hours after they were last known to be well and who had remaining ischemic brain tissue that was not yet infarcted. Patients with proximal middle-cerebral-artery or internal-carotid-artery occlusion, an initial infarct size of less than 70 ml, and a ratio of the volume of ischemic tissue on perfusion imaging to infarct volume of 1.8 or more were randomly assigned to endovascular therapy (thrombectomy) plus standard medical therapy (endovascular-therapy group) or standard medical therapy alone (medical-therapy group). Within the endovascular therapy plus standard medical therapy group, the Solitaire™ endovascular therapy group (Solitaire™ group) was dened as those subjects where the Solitaire™ Revascularization Device was used rst amongst other mechanical thrombectomy devices.
Inclusion Criteria
Subjects were considered eligible for the study if they satised all of the following inclusion criteria:
• Signs and symptoms consistent with the diagnosis of an acute anterior circulation ischemic stroke
• Age 18-90 years
• Baseline NIHSSS is ≥ 6 and remains ≥6 immediately prior to randomization
• Endovascular treatment can be initiated (femoral puncture) between 6 and 16 hours of stroke onset. Stroke onset is dened as the time the patient was last known to be at their neurologic baseline (wake-up strokes are eligible if they meet the above time limits).
• Modied Rankin Scale less than or equal to 2 prior to qualifying stroke (functionally independent for all ADLs)
• Patient/Legally Authorized Representative has signed the Informed Consent form.
In addition, neuroimaging inclusion criteria included:
• ICA or MCA-M1 occlusion (carotid occlusions can be cervical or intracranial; with or without tandem MCA lesions) by MRA or CTA
AND
• Target Mismatch Prole on CT perfusion or MRI (ischemic core volume is < 70 ml, mismatch ratio is > 1.8 and mismatch volume* is > 15 ml) *Notes: The mismatch volume is determined by the RAPID software in real time based on the dierence between the ischemic core lesion volume and the Tmax>6s lesion volume. If both a CT perfusion and a multimodal MRI scan are performed prior to enrollment, the later of the 2 scans is assessed to determine eligibility. Only an intracranial MRA is required for patients screened with MRA; cervical MRA is not required. Cervical and intracranial CTA are typically obtained simultaneously in patients screened with CTA, but only the intracranial CTA is required for enrollment.
Alternative neuroimaging inclusion criteria (if perfusion imaging or CTA/MRA is technically inadequate):
• If CTA (or MRA) is technically inadequate: a. Tmax>6s perfusion decit consistent with an ICA or MCA-M1 occlusion AND b. Target Mismatch Prole (ischemic core volume is < 70 ml, mismatch ratio is >1.8 and mismatch volume is >15
ml as determined by RAPID software)
• If MRP is technically inadequate: a. IC A or MCA-M1 occlusion (carotid occlusions can be cervical or intracranial; with or without tandem MCA lesions)
by MRA (or CTA, if MRA is technically inadequate and a CTA was performed within 60 minutes prior to the MRI) AND b. DWI lesion volume < 25 ml
• If CTP is technically inadequate: a. Patient can be screened with MRI and randomized if neuroimaging criteria are met.
Exclusion Criteria
Subjects were considered ineligible for study participation if they met any of the following exclusion criteria:
• Other serious, advanced, or terminal illness (investigator judgment) or life expectance is less than 6 months.
• Pre-existing medical, neurological or psychiatric disease that would confound the neurological or functional evaluations
• Pregnant
• Unable to undergo a contrast brain perfusion scan with either MRI or CT
• Known allergy to iodine that precludes an endovascular procedure
• Treated with tPA >4.5 hours after time last known well
• Treated with tPA 3-4.5 hours after last known well AND any of the following: age >80, current anticoagulant use, history of diabetes AND prior stroke, NIHSS >25
• Known hereditary or acquired hemorrhagic diathesis, coagulation factor deciency; recent oral anticoagulant therapy with INR > 3 (recent use of one of the new oral anticoagulants is not an exclusion if estimated GFR > 30 ml/min).
• Seizures at stroke onset if it precludes obtaining an accurate baseline NIHSS
• Baseline blood glucose of <50mg/dL (2.78 mmol) or >400mg/dL (22.20 mmol)
• Baseline platelet count < 50,000/uL
• Severe, sustained hypertension (Systolic Blood Pressure >185 mmHg or Diastolic Blood Pressure >110 mmHg)
• Current participation in another investigational drug or device study
• Presumed septic embolus; suspicion of bacterial endocarditis
• Clot retrieval attempted using a neurothrombectomy device prior to 6 hours from symptom onset
• Any other condition that, in the opinion of the investigator, precludes an endovascular procedure or poses a signicant hazard to the subject if an endovascular procedure was performed.
In addition, neuroimaging exclusion criteria included:
• ASPECT score <6 on non-contrast CT (if patient is enrolled based on CT perfusion criteria)
• Evidence of intracranial tumor (except small meningioma) acute intracranial hemorrhage, neoplasm, or arteriovenous malformation
14
• Signicant mass eect with midline shift
• Evidence of internal carotid artery dissection that is ow limiting or aortic dissec tion
• Intracranial stent implanted in the same vascular territory that precludes the safe deployment/removal of the neurothrombectomy device
• Acute symptomatic arterial occlusions in more than one vascular territory conrmed on CTA/MRA (e.g., bilateral MCA occlusions, or an MCA and a basilar artery occlusion).
Study Endpoints
The primary eectiveness endpoint of the study is 90-day blinded evaluation of modied Rankin Scale (mRS). Secondary ecacy endpoints were 1) functional independence at 90 days, dened as an mRS score ≤2 at day 90; and 2) change in NIHSS score between baseline and 24 hours of >8 points or a 24-hour NIHSS of 0-1.
The primary safety outcomes were death within 90 days and the occurrence of symptomatic intracranial hemorrhage within 36 hours, dened as an increase of at least 4 points in the NIHSS score that was associated with brain hemorrhage on imaging within 36 hours after symptom onset.
Results
The DEFUSE 3 study included a total of 182 subjects (92 in the endovascular therapy group and 90 in the control group). Solitaire™ was the rst device used amongst all mechanical thrombectomy devices for 38 subjects in the endovascular therapy group. The intention-to-treat (ITT) Analysis Cohort is thus comprised of 90 in the control group and 38 in the Solitaire™ group.
The DEFUSE 3 study allowed IV t-PA use beyond 3 hours, although IV t-PA is not approved in the United States beyond 3 hours. A total of 11 subjects (5 from the control group, 6 from the Solitaire™ group) were excluded from the primary and secondary ecacy endpoint analyses due to receiving IV t-PA beyond 3 hours and/or carotid stenting. Therefore, the primary and secondary ecacy endpoint analyses consist of 117 subjects (Analysis Cohort - mITT). In the mIT T Analysis Cohort, subjects with multiple interventions (n=8) were treated as failures. All analyses presented for the Analysis Cohort (ITT and mITT) are post-hoc analyses. As such, there may be uncertainty in the interpretation of the clinical study results and any statistically meaningful conclusions due to the post-hoc nature of the analyses, limitations in sample size, and lack of pre-specied hypothesis testing.

(Analysis Cohort - ITT). Hypothesis testing, including comparison of the primary ecacy endpoint between treatment groups, was conducted using two-sided tests with p-values less than 0.05 deemed signicant.
For adverse event reporting, the primary analysis is based on subject counts, not event counts. Both subject counts and event counts are presented in tabular summaries of results.
Note: The SFR3-6-24-06 and SFR3-6-40-10 models were not evaluated as part of the DEFUSE 3 study.
