SINUVA

The SINUVA Sinus Implant is a self-expanding, bioabsorbable, drug eluting implant provided with a crimper and a single-use delivery system. SINUVA Sinus Implant is comprised of poly(L-lactide-co-glycolide) and poly(L-lactide-co-⃞-caprolactone) coated with mometasone furoate embedded in a bioabsorbable polymer matrix containing poly(DL-lactide-co-glycolide) and polyethylene glycol (inactive ingredients) which provides for gradual release of the drug. The SINUVA Sinus Implant is packaged in a tray, which is then sealed in a foil pouch and placed in the product carton. The SINUVA Sinus Implant is provided sterile. Mometasone furoate, the active component of the SINUVA Sinus Implant, is a corticosteroid with the chemical name 9,21-dichloro-11(⃞),17-dihydroxy-16(⃞)-methylpregna-1,4-diene-3,20- dione 17 (2-furoate). Mometasone furoate is a white powder with an empirical formula of C 27 H 30 Cl 2 O 6 , and molecular weight of 521.44 Daltons. The chemical structure of mometasone furoate is shown below: The inactive ingredients are poly-(DL-lactide-co-glycolide) and polyethylene glycol. Poly-(DL-lactide-co-glycolide) is an amorphous biodegradable polymer. Chemical Structure

The SINUVA Sinus Implant is loaded into a Delivery System and placed in the ethmoid sinus under endoscopic visualization. The Implant may be left in the sinus to gradually release the corticosteroid over 90 days. Remove the implant by 90 days or earlier at the physician's discretion using standard surgical instruments. ( 2.2 ) To be inserted by physicians trained in otolaryngology. ( 2.3 ) 2.1 Recommended Dosage The recommended dosage is one SINUVA Sinus Implant (1350 mcg of mometasone furoate) placed in an ethmoid sinus [see Dosage and Administration (2.3) ] . The SINUVA Sinus Implant may be left in the sinus to gradually release the corticosteroid over 90 days. Remove the SINUVA Sinus Implant by 90 days or earlier at the physician's discretion [see Dosage and Administration (2.4) ] . 2.2 Health Care Provider Training The SINUVA Sinus Implant is to be used by physicians trained in otolaryngology. Specialized training is not required for these physicians . 2.3 Placement of SINUVA Sinus Implant The SINUVA Sinus Implant is designed for single patient use only. Do not reprocess or reuse. Do not use if the package is open, the package or product is damaged, or has evidence of gross contamination. Special care should be taken to avoid bending, twisting, or damaging the implant. The implant is not designed to be modified by the physician. The implant is not intended to be compressed and loaded into the Delivery System more than two times. The implant must be placed under endoscopic visualization. Patient Preparation The patient should be prepared following routine protocols for in-office sinonasal endoscopic procedures. Implant Preparation The SINUVA Sinus Implant (Figure 1) is loaded into a Delivery System and placed in the ethmoid sinus. Remove the Crimper (Figure 2) and the Delivery System (Figure 3) from their protective packaging using sterile technique. Inspect the SINUVA Sinus Implant located inside of the Crimper (Figure 2). Do not remove the Implant from the Crimper. Prior to use, the SINUVA Sinus Implant must be crimped and loaded into the Delivery System. If the SINUVA Sinus Implant is not fully seated inside of the Crimper, secure the SINUVA Sinus Implant before proceeding. See instructions to secure the SINUVA Sinus Implant (Figure 12–15). IMPLANT Length (nominal): 20 mm Expanded Diameter (nominal): 34 mm DELIVERY SYSTEM Shaft Length 117 mm Figure 1: Implant Figure 2: Crimper with Implant Figure 3: Delivery System Place the Crimper on a flat surface and hold to prevent any potential slipping of the Crimper during loading of the SINUVA Sinus Implant into the Delivery System. Orient the Crimper such that the short ends of the Implant are in the 12 o'clock and 6 o'clock position (Figure 4). Figure 4 Grasp the Delivery System with the index and middle fingers on the left or right hand using the Finger Rests and the thumb in the Thumb Rest (Figure 5). Figure 5 Pull back on the Finger Rests while pressing down on the Thumb Rest to retract the Cup and expose the Seeker (Figure 6). Figure 6 Position the tip of the Seeker with its 10° angled tip downwards toward the user in the depression in the center of the SINUVA Sinus Implant (Figure 7). The distal end of the angled shaft must be in a vertical position, perpendicular to the Crimper, during positioning. Ensure the plane of the angled tip is in the same plane as the short ends of the Implant that were oriented in the 12 o'clock / 6 o'clock position in step 1. Figure 7 With the Thumb Rest depressed, gradually apply perpendicular downward force to the SINUVA Sinus Implant until the ends of the Implant collapse around the Seeker of Delivery System (Figure 8). Make sure that the Finger Rests are not released while pushing downwards. Figure 8 The SINUVA Sinus Implant should crimp in a radial fashion onto the Seeker. Implant ends should not cross over or past each other when being crimped onto the Seeker by the Crimper. While maintaining steady downward pressure on the Thumb Rest, slowly release the Finger Rests with the index and middle fingers until the Cup lowers and captures all ends of the SINUVA Sinus Implant (Figure 9). If necessary, adjust the position of the Delivery System with slight circular movements, slightly lifting and then lowering the Cup into position to ensure that all eight ends of the SINUVA Sinus Implant are secured within the Cup. Figure 9 Apply a downward push on the Delivery System to ensure that the SINUVA Sinus Implant is secured in the Cup (Figure 10). This will also ensure the Implant is compressed to its smallest profile for insertion. Figure 10 Retract the Delivery System from the Crimper. The SINUVA Sinus Implant should remain symmetrically loaded in the Cup of the Delivery System (Figure 11). Figure 11 CAUTION: Do not leave the SINUVA Sinus Implant in the crimped state for more than 5 minutes prior to placement. Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Instructions to Secure the SINUVA Sinus Implant in the Crimper If necessary, the Implant may be reloaded into the Crimper for a second time. CAUTION: The SINUVA Sinus Implant should not be used if the second attempt to crimp is unsuccessful. Hold the SINUVA Sinus Implant by one end as shown in Figure 12. Figure 12 Holding the SINUVA Sinus Implant with the dome-shaped Cap positioned downward (Figure 13), place the Implant back into the Crimper. Figure 13 Ensure that each Implant is secured in the Crimper by pressing down on the center of the Implant until all ends of the Implant are below the rim of the Crimper (Figure 14). Figure 14 Inspect the Implant and the Crimper to ensure that all the Implant ends are secured below the rim of the Crimper (Figure 15). Return to Implant Preparation Step 1 for instructions on how to load the re-secured implant into the delivery system. Figure 15 Figure 12 Figure 13 Figure 14 Figure 15 Instructions for the SINUVA Sinus Implant Placement Advance the Delivery System under endoscopic visualization into the ethmoid sinus cavity. Ensure that the Delivery System is oriented such that the 10° curvature of the distal tip is curved superiorly. Insert the Delivery System such that the Shaft is parallel to roof of ethmoid sinus. If the SINUVA Sinus Implant becomes dislodged from the Delivery System prior to placement into the ethmoid sinus, remove the Implant and inspect for damage, re-load the undamaged Implant in the Crimper, and re-crimp the Implant into the Delivery System. Note that the SINUVA Sinus Implant should not be loaded into the Delivery System more than twice. Release the SINUVA Sinus Implant by pressing down on the Thumb Rest while pulling back on the Finger Rests in a controlled manner. Place the SINUVA Sinus Implant amongst the sinus polyps with the cap oriented toward the posterior ethmoid sinus, and with the Implant positioned as superiorly as possible in the sinus. The long ends of the Implant should be in approximately the 2 o'clock, 4 o'clock, 8 o'clock and 10 o'clock positions, respectively. Confirm final placement of the SINUVA Sinus Implant by endoscopic visualization. To adjust the position of the SINUVA Sinus Implant, use the Seeker on the Delivery System or standard endoscopic surgical instruments. Post Placement Instructions Reposition the Implant if its ends are perpendicular to and in contact with the nasal septum. Avoid excessive manipulation of the Implant during follow-up, as this can cause dislodgement. 2.4 Removal Instructions The SINUVA Sinus Implant is made from bioabsorbable polymers designed to gradually soften over time. Remove the SINUVA Sinus Implant by day 90 or earlier at the physician's discretion using standard endoscopic instruments.

The safety of the SINUVA Sinus Implant was evaluated and demonstrated in 400 patients in 2 controlled, randomized, parallel group, single-blind studies. In Study 1, one-hundred (100) subjects were followed for 6 months. In Study 2, three-hundred (300) subjects were followed for 90 days. Of the 400 patients, 254 were assigned to the treatment group and underwent bilateral placement of SINUVA Sinus Implants in the ethmoid sinuses, totaling 2700 mcg of mometasone furoate, and 146 patients were assigned to the control group and underwent a sham procedure consisting of advancement of the Delivery System with the SINUVA Sinus Implant followed by removal without deployment. The Implants were removed by Day 60. All patients were required to use mometasone furoate nasal spray once daily (200 mcg of mometasone furoate) through Day 90. Table 1 shows the common adverse reactions (in greater than 1% of subjects) that occurred more frequently in patients treated with SINUVA Sinus Implant compared to the control group. Table 1: Adverse Reactions with > 1% Incidence and More Common than Control in 90-Day Controlled Clinical Trials with SINUVA Sinus Implant Study 1 & Study 2 Combined Data Adverse Reaction Treatment Patients in the treatment group received SINUVA Sinus Implants placed bilaterally in the ethmoid sinuses and used mometasone furoate nasal spray once daily (200 mcg mometasone furoate) through Day 90. (N = 254) n (%) Control Patients in the control group underwent a sham procedure and used mometasone furoate nasal spray once daily (200 mcg mometasone furoate) through Day 90. (N = 146) n (%) Values represent patient counts and percentages. A patient reporting more than one adverse event for a particular MedDRA preferred term is counted only once. Asthma 12 (4.7) 6 (4.1) Headache 9 (3.5) 5 (3.4) Epistaxis 6 (2.4) 2 (1.4) Presyncope 6 (2.4) 3 (2.1) Bronchitis 5 (2.0) 2 (1.4) Otitis media 5 (2.0) 2 (1.4) Nasopharyngitis 3 (1.2) 1 (0.7) Study 1 monitored patients from Day 90 through 6 months. Hypersensitivity (4% (n=2) vs. 0), chronic rhinosinusitis (11% (n=6) vs. 9% (n=4)), and upper respiratory tract infections (8% (n=4) vs. 2% (n=1)) were reported in more than 2 subjects in the treatment group, and more commonly than the control group during this time period. The safety of repeat administration of the SINUVA Sinus Implant was evaluated in Study 3 that was an open-label, single-arm, multicenter study in 50 patients. All patients underwent an in- office bilateral placement of the SINUVA Sinus Implant in each ethmoid sinus (totaling 2 implants) and were followed for 365 days. Patients were required to use mometasone furoate nasal spray once daily (200 mcg of mometasone furoate) through 365 days. At 90 days, the remaining implants were removed. To maximize the size of the safety population, patients with ethmoid sinus polyps grade ≥ 1 on any side were considered for repeat implant placement. Repeat placement was not performed if polyp grade was < 1, or if the patient declined it. Of the 50 patients, 41 received repeat implant placement (33 bilaterally and 8 unilaterally). Acute sinusitis (29%, n=12), upper respiratory infection (17%, n=7) epistaxis (12%, n=5), nasal discomfort or rhinalgia (12%, n=5), headache (7%, n=3), were the common adverse reactions that occurred in at least 3 subjects who underwent repeat placement during the study period. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of the SINUVA sinus implant. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to SINUVA, or a combination of these factors, include: implant migration, lack of efficacy, nasal pain, headache, epistaxis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug experience.

Formal drug-drug interaction studies have not been conducted with the SINUVA Sinus Implant. An evaluation of the concurrent administration of the SINUVA Sinus Implant and other commonly used nasal drugs was not associated with any unusual adverse reactions. 7.1 Inhibitors of Cytochrome P450 3A4 Co-administration with ketoconazole, a potent CYP 3A4 inhibitor, may increase the plasma concentrations of mometasone furoate [see Clinical Pharmacology (12.3) ] .
