EUFLEXXA is a viscoelastic, sterile solution of highly purified, high molecular weight (2.4-3.6 million daltons) hyaluronan (also known as sodium hyaluronate) in phosphate-buffered saline. EUFLEXXA is a very highly purified product extracted from bacterial cells. It is a polysaccharide consisting of a repeating disaccharide of N-acetylglucosamine and sodium glucuronate, linked by alternating β → 1,3 and β → 1,4 glycosidic bonds.
EUFLEXXA (1% sodium hyaluronate) is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics (e.g., acetaminophen).
- Do not use EUFLEXXA to treat patients who have a known hypersensitivity to hyaluronan preparations.
- Do not use EUFLEXXA to treat patients with knee joint infections, infections or skin disease in the area of the injection site.
- Mixing of quaternary ammonium salts such as benzalkonium chloride with hyaluronan solutions results in formation of a precipitate.
EUFLEXXA should not be administered through a needle previously used with medical solutions containing benzalkonium chloride. Do not use disinfectants for skin preparation that contain quaternary ammonium salts.
- Do not inject intravascularly because intravascular injection may cause systemic adverse events.
- Patients having repeated exposure to EUFLEXXA have the potential for an immune response; however, this has not been assessed in humans.
- Safety and effectiveness of injection in conjunction with other intra-articular injectables, or into joints other than the knee has not been established.
- Remove any joint effusion before injecting.
- Transient pain or swelling of the injected joint may occur after intra-articular injection with EUFLEXXA.
- Do not use after expiration date.
- Protect from light.
- Do not re-use—dispose of the syringe after use.
- Do not use if the blister package is opened or damaged.
Information for Patients
- Provide patients with a copy of the Patient Information prior to use.
- Transient pain and/or swelling of the injected joint may occur after intra-articular injection of EUFLEXXA.
- As with any invasive joint procedure, it is recommended that the patient avoid any strenuous activities or prolonged (i.e., more than 1 hour) weight-bearing activities such as jogging or tennis within 48 hours following intra-articular injection.
- The safety of repeated treatment cycles of EUFLEXXA has been established up to 1 year.
Use in Specific Populations
- Pregnancy: The safety and effectiveness of EUFLEXXA have not been established in pregnant women.
- Nursing Mothers: It is not known if EUFLEXXA is excreted in human milk. The safety and effectiveness of EUFLEXXA have not been established in lactating women.
- Children: The safety and effectiveness of EUFLEXXA have not been demonstrated in children.

12 Week Multicenter Clinical Study
This clinical investigation was a prospective randomized, double-blinded, active control (commercially available hyaluronan product) study conducted at 10 centers. Three hundred twenty-one patients were randomized into groups of equal size to receive either EUFLEXXA (n=160) or the active control (n=161).
A total of 119 patients reported 196 adverse events; this number represents 54 (33.8%) of the EUFLEXXA group and 65 (44.4%) of the active control group. There were no deaths reported during the study. Incidences of each event were similar for both groups, except for knee joint effusion, which was reported by 9 patients in the active control group and one patient in the EUFLEXXA treatment group. Fifty-two adverse events were considered device-related. Table 1 lists the adverse events reported during this investigation.

*Treatment group for repeat study are for subjects who received EUFLEXXA in both the core and extension (219 out of 433).
N = number of subjects in a given treatment group for the population analyzed; n = number of subjects reporting at least one adverse event within system organ class/preferred term; (%) = percentage of subjects based on N; TEAE = treatment-emergent adverse event.
Note: An adverse event was counted as a TEAE if it was either not present at baseline (prior to the first dose of double-blind study device) or present at baseline but increased in severity during the treatment period.
During the initial randomization/treatment phase, 326 (55.4%) subjects in the safety population experienced 742 TEAEs. The proportion of subjects reporting TEAEs was generally similar in the EUFLEXXA and saline groups (53.6% and 57.3%, respectively) . The most common preferred term of TEAE was arthralgia (10.5% of all subjects). Thirty (5.1%) subjects experienced severe TEAEs, and the proportion with severe events was larger in the saline group (6.4%) than the EUFLEXXA group (3.8%). Overall, 10.4% of subjects had TEAEs considered related to study device, with comparable proportions in each treatment group (9.9% and 10.8% for EUFLEXXA and saline, respectively).
During the extension phase, 43.4% (188/433) of subjects reported 377 TEAEs. Of these 43.8% (96/219) subjects receiving repeated EUFLEXXA reported 199 TEAEs. The most frequently reported preferred term in subjects formerly assigned to the core study EUFLEXXA group were arthralgia (8.7%), nasopharyngitis (4.6%), injury (4.1%), upper respiratory tract infections (2.7%), joint swelling (2.7%), back pain (2.7%), and sinusitis (2.3%). Of these TEAEs 9 (4.1%) subjects had study device related AEs classified as “Certain,” “Probable,” “Possible” or “Un-assessable.” The most common related TEAEs were arthralgia (2.3%) and joint swelling (1.4%). Table 4 shows the Study Device Related Treatment-Emergent Adverse Events by Preferred Term with an Incidence of > 1 among Treatment Groups (Safety Population).

Twenty-three serious TEAEs were reported in 19 (3.2%) subjects during the study: 10 (3.4%) subjects in the EUFLEXXA group and 9 (3.1%) subjects in the saline group. One of these events was considered related to the study device (increased redness of the left knee joint in the EUFLEXXA group) . Eight (1.4%) subjects had 9 TEAEs leading to discontinuation: 3 (1.0%) subjects in the EUFLEXXA group and 5 (1.7%) subjects in the saline group.
Twelve (2.8%) subjects reported 20 serious TEAEs during the extension phase. Six of these subjects had received EUFLEXXA during the core study. None of the serious TEAEs was considered related to study device, and all resolved. Two (0.5%) subjects had TEAEs leading to discontinuation from the study, one of whom received EUFLEXXA during the core study; both subjects had events that were considered unrelated to study device.
Two subjects on saline experienced joint effusion. There were no reports of joint effusion among subjects receiving EUFLEXXA during the core and extension phase.
12 Week Multicenter Clinical Trial
The safety and effectiveness of EUFLEXXA as a treatment for pain in OA of the knee was investigated in a multicenter clinical trial conducted in Germany.
The clinical investigation was a prospective randomized, double blinded, active control (commercially available hyaluronan) study conducted at 10 centers in Germany. A total of 321 patients with stage 2 – 3 osteoarthritis of the knee according to the Kellgren and Lawrence grading system, meeting the Altman Criteria for Classification of Idiopathic Osteoarthritis of the knee, and scoring an average score of 41 – 80 mm on the WOMAC VAS pain index were randomized into groups of equal size to receive either EUFLEXXA (160 patients) or the active control (161 patients).
Patient Population and Demographics
The demographics of trial participants were comparable across treatment groups with regard to age, gender, Kellgren and Lawrence grading system, stiffness, crepitus, bony enlargement, and no palpable warmth. Table 5 lists the demographics of the patient population.
|Parameter||Number of Patients (%)|
|† Kellgren and Lawrence Grading System|

† Kellgren and Lawrence (Ann Rheum Dis 1957;(16):494-501): Based on radiological findings, osteoarthritis stages were defined as follows: 0 = normal, 1 = doubtful narrowing of joint space and possible osteophytic lipping, 2 = definite osteophytes and possible narrowing of joint space, 3 = moderate multiple osteophytes and definite narrowing of joint space, some sclerosis and possible deformity of bone contour, 4 = large osteophytes, marked narrowing of joint space, severe sclerosis and definite deformity of bone contour.
‡ Altman, et al., (Arthritis and Rheumatism 1986;29(8):1039-1049): Clinical criteria for classification of idiopathic osteoarthritis (OA) of the knee were defined as follows: Knee pain and at least 3 of the following 6 parameters: Age > 50 years, Stiffness < 30 minutes, Crepitus, Bony tenderness, Bony enlargement, No palpable warmth.
For this trial, the main performance analysis for determining non-inferiority was determined using the improvement in the average of the five patient’s self-evaluation pain parameters measured by the VAS WOMAC index at Week 12 from baseline. This analysis was performed for both the intent-to-treat population, (i.e., every subject who received the injection), and the evaluable population, (i.e., those subjects who had average pain scores of 41-80 allowing only one parameter to be below 20 or above 80 at both the pre-screening visit and visit 1). For those patients who dropped out of the study before Week 12, the last evaluation was used. For those patients who requested NSAID or analgesic during the study, the last evaluation before start of NSAID/analgesic was used for the analysis. The results indicate that the effect of EUFLEXXA on pain relief was not inferior to that of a commercially available hyaluronan.

26 Week Multicenter Clinical Trial
This was a multicenter, randomized, double-blind trial evaluating the efficacy and safety of EUFLEXXA as compared to saline comparator in subjects with chronic osteoarthritis of the knee. The intervention consisted of three weekly injections into the target knee with evaluations from baseline through Week 26 (1, 2, 3, 6, 12, 18, and 26). The primary objective was to demonstrate superiority over saline comparator from baseline to Week 26 using the pain level reported following a 50 foot walk test, measured by 100 mm visual analog scale. The following secondary endpoints were also evaluated: OARSI responder rate at Week 12 and Week 26; WOMAC pain, disability, and joint stiffness score changes from baseline to Week 12 and 26; and change in Patient Global Assessment from baseline to Week 12 and Week 26.
Patient Population and Demographics
A total of 821 subjects were screened for the study, and 588 subjects were randomized. Approximately 88% of the randomized subjects completed the study, with similar proportions completing in each treatment group. Sixty-eight (11.6%) subjects discontinued the randomization/treatment phase prematurely: 34 (11.5%) in the saline group and 34 (11.6%) in the EUFLEXXA group. The most common reasons for discontinuation were the subject’s withdrawing consent 25 (4.3%) and AEs 17 (2.9%). A total of 433 (73.6%) subjects entered the open-label extension study.
In the primary efficacy analysis, the EUFLEXXA group showed a larger mean decrease in pain scores on the 50-foot walk test from baseline to Week 26 than the saline group: - 25.7 (28.85) mm versus -18.5 (32.53) mm, respectively. The group difference in least squares mean change from baseline of -6.6 mm (95% CI = -10.8 to -2.5 mm) was statistically significant (p- value = 0.002). Figure 1 depicts the adjusted mean change in pain scores on 50-foot walk test from baseline to week 26 (ITT Population).
