## Device Story

XIENCE family of everolimus-eluting coronary stents; cobalt-chromium (CoCr) alloy stent platform; coated with everolimus embedded in non-erodible polymer (PBMA and PVDF-HFP); mounted on rapid-exchange (RX) or over-the-wire (OTW) delivery system. Used in cardiac catheterization labs by interventional cardiologists to treat coronary artery disease. Stent deployed via balloon inflation to improve luminal diameter; everolimus released to inhibit restenosis. Clinical benefit: reduced restenosis and target lesion revascularization compared to bare metal stents. Output is physical vessel support and localized drug delivery. Expanded indication includes diabetic patients.

## Clinical Evidence

### Drug Component Description for the XIENCE Family of Stents

The XIENCE Family of Everolimus Eluting Coronary Stents are coated with everolimus (active ingredient), embedded in a non-erodible polymer (inactive ingredient).

### Everolimus

Everolimus is the active pharmaceutical ingredient in the XIENCE stents. It is a novel semi-synthetic macrolide immunosuppressant, synthesized by chemical modification of rapamycin (sirolimus). The everolimus chemical name is 40-O-(hydroxyethyl)-rapamycin and the chemical structure is shown in Figure 1 below.

### Inactive Ingredients – Non-erodible Polymer

The XIENCE V stent contains inactive ingredients including poly n-butyl methacrylate (PBMA), a polymer that adheres to the stent and drug coating, and PVDF-HFP, which is comprised of vinylidene fluoride and hexafluoropropylene monomers as the drug matrix layer containing everolimus. PBMA is a homopolymer with a molecular weight (Mw) of 264,000 to 376,000 dalton. PVDF-HFP is a non-erodible semi-crystalline random copolymer with a molecular weight (Mw) of 254,000 to 293,000 dalton. The drug matrix copolymer is mixed with everolimus (83%/17% w/w polymer/everolimus ratio) and applied to the entire PBMA coated stent surface.

The drug load is 100 μg/cm² for all product sizes. No topcoat layer is used. The polymer chemical structures are shown in Figure 2 below.

## **IX. SUMMARY OF PRECLINICAL STUDIES**

A series of non-clinical laboratory studies related to the XIENCE Family of Stents were performed and the pertinent data is being leveraged from the previously approved PMAs P070015 and P110019.

## **X. SUMMARY OF PRIMARY CLINICAL STUDY**

The applicant performed a prospective analysis to establish a reasonable assurance of safety and effectiveness of percutaneous coronary intervention with the XIENCE Family of Stents for patients with diabetes mellitus in the US. Data from this analysis were the basis for the PMA approval decision. A summary of the clinical study is presented below.

### **A. Study Design**

A prospective analysis was designed to evaluate the safety and effectiveness of the XIENCE Family of Stents for patients with diabetes mellitus using one-year clinical data of diabetic patients from four AV-sponsored XIENCE stent clinical studies [SPIRIT IV (IDE G050050), SPIRIT PRIME (IDE G090068), XIENCE V USA first enrolment phase of 5,000 patients (IDE G050050), and XIENCE V USA second enrollment phase of 3,000 patients (IDE G050050)] and two external registry databases [Cleveland Clinic (CC) and the Wake Forest Baptist Medical Center (WFBMC)]. The two external databases are real-world observational registries, which are part of the National Cardiovascular Data Registry (NCDR) CathPCI registry.

A Bayesian hierarchical model was utilized to analyze the primary endpoint of target vessel failure (TVF) at 12 months, defined as a composite of cardiac death, target-vessel myocardial infarction (TVMI), or ischemia driven target vessel revascularization (ID-TVR). The TVF rate was tested against a prespecified performance goal (PG) of 14.8% (expected rate 8.6% plus a delta of 6.2%).

An “on-label” diabetic patients (including those who are treated with XIENCE 33 or 38 mm stent) from each trial/registry database were included in the analysis. Patients were considered as “on-label” diabetic if they had diabetes mellitus at baseline, had at least one XIENCE stent implanted during the index procedure, and satisfied the following criteria:

- Lesions/vessels which were treated during the index procedure:
  - Only de novo lesion
  - No chronic total occlusion lesion
  - No vessel thrombosis
  - No graft lesion
  - No bifurcation lesion
  - No left main lesion
  - At most two vessels treated, one lesion treatment per vessel
  - Reference vessel diameter between 2.25 and 4.25 mm (based on quantitative coronary angiography, visual assessment, or final balloon size pre-stent implantation)

PMA P070015/ S128 and P110019/S075: FDA Summary of Safety and Effectiveness Data
Page 24

{24}

○ Lesion length <32 mm (visual assessment)
○ If treated with a 33 or 38 mm XIENCE stent, only one 33 or 38 mm XIENCE stent treatment is allowed (overlapping with other length XIENCE stent is allowed)
• No acute myocardial infarction
• No renal insufficiency
• No staged procedure
• Left ventricular ejection fraction >30%

The statistical hypothesis was as follows:

$$H_0: \text{TVF} \geq 14.8\% \text{ vs. } H_a: \text{TVF} < 14.8\%.$$

The analysis was designed to support a claim that the TVF rate at 12 months for the XIENCE stent in on-label diabetic patients (including patients treated with a single 33 or 38 mm XIENCE stent) meets a PG of 14.8%. The study was considered to be successful if the posterior probability of a TVF rate <14.8% was greater than 0.975.

The results from the four AV-sponsored trial databases (SPIRIT IV, SPIRIT PRIME, XIENCE V USA first enrollment phase, and XIENCE V USA second enrollment phase) were considered as prior information. The two external XIENCE databases from CC and WFBMC were pooled as current data and served as the basis for statistical inference.

### B. Number of Patients included in the PMA Cohort

There were 1,239 diabetic XIENCE patients included in this analysis: 451 from SPIRIT IV, 121 from SPIRIT PRIME, 185 from XIENCE V USA first enrollment phase, 192 from XIENCE V USA second enrollment phase, and 290 from pooled external databases (156 from CC and 134 from WFBMC, respectively).

### Study Population Demographics and Baseline Parameters

The mean age of the diabetic population was 63 years from the pooled historical AV trials (SPIRIT IV, SPIRIT PRIME, XIENCE V USA first enrollment phase and second enrollment phase) and 65 years from the pooled two external databases (Wake Forest and Cleveland Clinic). There were 62.8% males from the pooled AV trials and 64.1% from the pooled external databases. Insulin treated diabetic patients comprised of 25.9% and 35.5% of the overall diabetic analysis population from the pooled AV trials and pooled external databases, respectively. A total of 26.6% of patients presented with unstable angina from the pooled AV trials and 57.6% from the pooled external databases. There were 23.8% and 35.9% patients who had prior MI, 34.2% and 44.8% who had prior PCI, and 10.5% and 24.5% who had prior CABG from the pooled AV trials and pooled external databases, respectively. The mean lesion length was 13.5 mm for the pooled AV trials, and 16.3 mm for the pooled external databases. There were 12.0% type C lesions in the pooled AV trials and 25.5% in the pooled external databases. There were 2.6% (32/1239) patients treated with 33 or 38 mm stents in this pooled dataset (2.5% from the pooled AV trials, and 2.8% from the pooled external databases). Compared to the pooled AV

PMA P070015/ S128 and P110019/S075: FDA Summary of Safety and Effectiveness Data

Page 25

{25}

trials, patient and lesion characteristics in the two external databases were generally more complex, likely due to their non-trial real-world settings.

### C. Primary Endpoint Results

The primary endpoint of 1-year TVF rate was 8.04% based on the Bayesian binomial-normal hierarchical model where prior data from AV historical trials were taken into consideration. The 95% credible interval of TVF was between 5.23% and 11.52%. The posterior probability of a 1-year TVF rate <14.8% was >0.999, which exceeds the pre-specified success criteria (>0.975). Therefore, the analysis has met its pre-specified success criteria for the primary endpoint of 1-year TVF.

Table 11 Bayesian Analysis for the Primary Endpoint

|  Primary Endpoint | TVF Rate [95% Central Posterior Interval]* | Bayesian Posterior Probability (TVF < 14.8%)  |
| --- | --- | --- |
|  1-year TVF | 8.04% [5.23%, 11.52%] | > 0.999  |

* The posterior mean is the Bayesian posterior average; the 95% central posterior interval is the symmetric 95% Bayesian credible interval, similar to the 95% confidence interval.

Notes:

- The 1-year window is through 393 days (365 + 28 days).
- TVF is defined as hierarchical composite of cardiac death, target vessel MI, and ischemia-driven TVR. For the primary composite endpoint of TVF, an adjustment factor of 0.826 was applied for Cleveland Clinic to calculate the TVF rate based on the composite rate of all death/all MI/all TVR as the specifics of these events were not available from the Cleveland Clinic database.

The 1-year clinical outcomes of the XIENCE diabetic population from each of the AV trials (SPIRIT IV, SPIRIT PRIME and XIENCE V USA) and the pooled two external databases are shown in Table 11.

- MI from the historical AV trials was defined per protocol and was categorized as Q-wave (development of new, pathological Q waves on the ECG) or non-Q-wave (elevation of CK levels to greater than two times the upper limit of normal and elevated CK-MB in the absence of new pathological Q waves). For the two external databases, MI was defined based on Universal MI definition per the National Cardiovascular Data Registry (NCDR) requirement.
- For the primary composite endpoint of TVF, an adjustment factor of 0.826 was applied to one of the two external databases in order to calculate the TVF rate based on the composite rate of all death/all MI/all TVR, as the specifics of these events were not available from that database.
- For other endpoints (TLF, cardiac death or TVMI, ID-TLR, ID-TVR, cardiac death and TVMI), only one of the external databases was included in the analysis, as the specific event information was not available in the other external database.

The results of this analysis support the indication for use of the XIENCE Family of Stents in patients with diabetes mellitus.

## **XI. PANEL MEETING RECOMMENDATION AND FDA'S POST-PANEL ACTION**

In accordance with the provisions of section 515(c)(2) of the act as amended by the Safe Medical Devices Act of 1990, this PMA was not referred to the Circulatory System Devices Panel, an FDA advisory committee, for review and recommendation because the information in the PMA substantially duplicates information previously reviewed by this panel.

## **XII. CONCLUSIONS DRAWN FROM PRECLINICAL AND CLINICAL STUDIES**

### **A. Safety and Effectiveness Conclusions**

With regard to safety and effectiveness, the primary endpoint of target vessel failure (which consists of cardiac death, target vessel MI, and ischemia driven target vessel revascularization) is a composite of safety and effectiveness.

In the diabetic indication analysis presented herein, the posterior mean for the 1-year primary endpoint TVF was 8.04%. The 95% central posterior interval of TVF was between 5.23% and 11.52%. The posterior probability of a TVF rate <14.8% is > 0.999, which exceeds the pre-specified success criteria (>0.975). Therefore, the analysis has met its pre-specified success criterion for the primary endpoint of 1-year TVF. These 1-year clinical data from the internal AV trials and external databases support the safety and effectiveness of the XIENCE Family Stents in the treatment of diabetic patients with coronary artery disease.

### **B. Benefit-Risk Conclusions**

The probable benefits of the device are also based on the data analysis conducted to support PMA approval as described above.

Percutaneous revascularization with coronary stent placement has been widely used as an alternative to medical or surgical treatment in selected patients with symptomatic coronary artery disease. The major limitations of PTCA (including but not limited to acute closure, intimal dissection, and restenosis) are overcome to a significant extent with coronary stents. The XIENCE Family of Stents is designed to improve luminal diameter and maintain arterial patency. Available clinical study data support acceptable event rates in diabetic patients treated with everolimus-eluting stents (EES). Diabetic patients benefit from treatment with EES because the use of bare metal stents is associated with the high rates of restenosis and target lesion revascularization.

Additional factors to be considered in determining probable risks associated with using this device are those associated with percutaneous coronary diagnostic procedures (including

angiography and IVUS) and treatment procedures. These risks are discussed in detail in Section VIII, 'POTENTIAL ADVERSE EFFECTS OF THE DEVICE ON HEALTH' of this SSED.

XIENCE stent treatment in diabetic patients demonstrated acceptable rates of TVF, the individual components of TVF (cardiac death, MI, and target lesion revascularization) and stent thrombosis.

In conclusion, based on the 1-year data, the probable benefits of the devices in the XIENCE Family of Stents in the treatment of coronary artery disease in diabetic patients outweigh the probable risks.

### C. Overall Conclusions

The data in this application support the reasonable assurance of safety and effectiveness of this device when used in accordance with the indications for use.

The results of the prospective analysis of a diabetic population from four AV historical trials (SPIRIT IV, SPIRIT PRIME, XIENCE V USA first enrollment phase, XIENCE V USA second enrollment phase) and two external registry databases (CC and WFBMC) met the pre-specified success criteria based on a Bayesian analyses. The posterior mean for the primary endpoint of 1-year TVF rate was 8.04%, with 95% credible interval between 5.23% and 11.52%. The posterior probability of a TVF rate <14.8% is > 0.999, which exceeds the pre-specified success criteria (>0.975). These 1-year clinical data from internal AV trials and external databases support the safety and effectiveness of the XIENCE Family of Stents in the treatment of diabetic patients with coronary artery disease.
