What's The Definition Of The Medical Condition Non-animal Stabilized Hyaluronic Acid Injectable Gel with 0.3% Lidocaine?Clinical Pharmacology CLINICAL PHARMACOLOGY Clinical Trials The safety and effectiveness of Perlane in the treatment of facial folds and wrinkles (nasolabial folds and oral commissures) were evaluated in four prospective randomized controlled clinical studies involving 509 Perlane-treated patients.
Perlane was shown to be effective when compared to cross-linked collagen and cross-linked hyaluronic acid dermal fillers with respect to the correction of moderate to severe facial folds and wrinkles, such as nasolabial folds.
The safety and pain reduction effect of Perlane-L in the treatment of facial folds and wrinkles (nasolabial folds) was evaluated in a prospective randomized controlled clinical study involving 60 patients.
The addition of lidocaine to Perlane resulted in a statistically significant reduction in the pain experienced by the patients.
The study also showed that the safety profile of Perlane-L was consistent with Perlane.

centers, which compared the safety and effectiveness of Perlane and Restylane following treatment to baseline condition.
Patients were randomized to either Perlane or Restylane treatment.
A touch-up was allowed 2 weeks after initial treatment.
Patients were partially masked; evaluating physicians were independent and masked; treating physicians were unmasked.
Effectiveness was studied with 6 months follow-up.
Safety was studied with 6 months follow-up.
Endpoints Effectiveness Primary The difference in effect of Perlane at week 12 versus baseline condition on the visual severity of the nasolabial folds, as assessed by the Blinded Evaluator.
The primary study endpoint was wrinkle severity 12 weeks after optimal correction was achieved.
Wrinkle severity was evaluated on a five-step validated Wrinkle Severity Rating Scale (WSRS) (i.e., none, mild, moderate, severe, extreme) by a live evaluator blinded to treatment.
Patient success was defined as maintaining at least a one point improvement on the WSRS at 12 weeks after optimal correction was achieved.
The percent of patient successes was calculated for each treatment group.
Each group was compared to its own baseline, with no comparison of Perlane to Restylane.
Secondary Wrinkle Severity Rating Scale (WSRS) assessed at other follow-up points (2, 6, and 24 weeks after optimal correction) by the Blinded Evaluator, the investigator and the patient and compared to baseline score by the same evaluator.
Duration of effect defined as 6 months or time point, if earlier, at which less than 50% of patients had at least a 1-grade response remaining in both nasolabial folds (NLFs).
Safety assessments included: collection of patient symptoms in a 14-day diary; investigator evaluation of adverse events at 72 hours, and at 2, 6, 12, and 24 weeks; development of humoral or cell-mediated immunity; and the relationship of adverse events to injection technique.
Outcomes Demographics The study enrolled 283 (i.e., 141 Perlane and 142 Restylane) patients with moderate to severe NLF wrinkles.
The patients were predominantly healthy ethnically diverse females.
Bilateral NLFs and oral commissures were corrected in most patients with 1.9 mL to 4.6 mL of Perlane.
The greatest amount used in any patient was 9.0 mL.
Gender – Female: 266 (94%); Male: 17 (6%) Ethnicity – White: 226 (80%); Hispanic or Latino: 31 (11%); African American: 23 (8%); Asian: 3 (1%) Efficacy The results of the blinded evaluator assessment of NLF wrinkle severity for Perlane and control (Restylane) are presented in Table 11.
In the primary effectiveness assessment at 12 weeks, 87% of the Perlane and 77% of the control patients had maintained at least a 1 point improvement over baseline.

One patient also developed a measurable increase in antibody titer after Perlane injection.
4/16 (27%) patients with antibodies against Perlane had adverse events at the injection site, which was similar to the local adverse event rate observed in the entire Perlane population (i.e., 49/141 (35%)).
With the exception of one moderate bruising event, all the adverse events in the patients with a humoral response against Perlane were mild in severity.
No severe events were noted and the patient who developed an antibody response after Perlane injection did not experience any adverse event at the injection site.
Immediate type skin testing demonstrated that no patient developed IgE to Perlane.
Post-exposure histopathology of skin biopsies of an implant site on each patient demonstrated that no patient developed cell-mediated immunity to Perlane.

centers, which compared the safety and effectiveness of Perlane and Restylane following treatment to baseline condition in 150 patients with pigmented skin and predominantly African-American ethnicity.
Patients were randomized to either Perlane or Restylane treatment in a “within-patient” model of augmentation correction of bilateral nasolabial folds (NLFs) and oral commissures with one treatment assigned to one side and the other treatment to the other side.
A touch-up was allowed 2 weeks after initial treatment.
Patients and treating physicians were partially masked.
Evaluations were performed by live investigator assessment for the primary analysis.
Effectiveness was studied with 6 months follow-up.
Safety was studied with 6 months follow-up.
Endpoints Effectiveness Primary The difference in effect of Perlane at week 12 versus baseline condition on the visual severity of the NLFs.
The primary study endpoint was wrinkle severity 12 weeks after optimal correction was achieved.
Wrinkle severity was evaluated with a five-step validated Wrinkle Severity Rating Scale (WSRS) (i.e., none, mild, moderate, severe, extreme) by an on-site Blinded Evaluator.
Patient success was defined as maintaining at least a one point improvement on the WSRS at 12 weeks after optimal correction was achieved.
The percent of patients success was calculated for each group.
Each treatment group was compared to its own baseline, with no comparison of Perlane to Restylane.
Secondary Wrinkle Severity Rating Scale (WSRS) was assessed at other follow-up points (2, 6, and 24 weeks after optimal correction) by the investigator and the patient and compared to baseline score by the same evaluator.
A photographic assessment of patient outcomes was also performed.
Duration of effect defined as 6 months or time point, if earlier, at which less than 50% of patients had at least a 1-grade response at both nasolabial folds.
Safety assessments included: collection of patient symptoms in a 14-day diary; investigator evaluation of adverse events at 72 hours, and at 2, 6, 12, and 24 weeks; the development of humoral or cellmediated immunity; and the relationship of adverse events to injection technique.
Outcomes Demographics The study enrolled 150 patients with moderate to severe NLF wrinkles.
The patients were predominantly healthy African-American females.

All the adverse events in the patients with a humoral response against Perlane were mild in severity.
Immediate type skin testing demonstrated that no patient developed IgE to Perlane.
Post-exposure histopathology of skin biopsies of an implant site on each patient demonstrated that no patient developed cell-mediated immunity to Perlane.
MA-1400-03: Randomized, Blinded, Controlled Clinical Study Design 1:1 randomized, prospective study at 3 U.S.
centers, which compared the safety, tolerability, and pain reduction of Perlane-L to Perlane in 60 patients.
Patients were randomized to Perlane-L or Perlane treatment in a “within-patient” model of bilateral nasolabial folds (NLFs) correction, with one treatment assigned to one side and the other treatment to the remaining side.
Patients and treating physicians were blinded; evaluating physicians were independent and blinded.
The study included 51.7% of patients with darker skin types based on classification of Fitzpatrick Skin Types IV, V, or VI (36.7% Skin Type IV and 15.0% Skin Type V or VI).
Pain was assessed by each patient for each treatment site independently on the Visual Analog Scale (VAS) at the end of injection and at 15-minute intervals for 60 minutes post-treatment.
Patient assessment of appearance using the Global Aesthetic Improvement Scale (GAIS) (Very much improved / much improved / improved / no change / worse) was performed at the Day 14 visit.
Safety was studied with 14-day follow-up.
Endpoints Primary The proportion of patients that had a within-patient difference in the VAS (Perlane – Perlane-L) of at least 10 mm at injection together with a 95% confidence interval.
The objective was to show that the confidence interval lay above 50%.
Secondary The proportion of patients that had a within-patient difference in VAS of at least 10 mm at postinjection time points (15, 30, 45 and 60 minutes after injection) together with a 95% confidence interval, the mean VAS by treatment and within-patient difference in VAS at each time point, the comparison of VAS between Perlane-L and Perlane, at each time point, and patient assessment on GAIS by treatment.
Safety assessments included: collection of patient symptoms in a 14-day diary and investigator evaluation of adverse events at 14 days.
Outcomes Demographics The study enrolled 60 patients with moderate to severe NLF wrinkles.
The patients were predominantly healthy ethnically diverse females.
Gender – Female: 56 (93.3%); Male: 4 (6.7%) Ethnicity – White: 39 (65.0%); Hispanic or Latino: 16 (26.7%); African American: 5 (8.3%) Fitzpatrick Skin Type- Type I-III; 29 (48.3 %); Type IV: 22 (36.7%); Type V and VI: 9 (15.0%) Volume The mean volume of Perlane-L per wrinkle was 1.11 mL.
The mean volume of Perlane per wrinkle was 1.10 mL.

The primary objective was met, since statistically more than 50% of patients had at least 10 mm lower VAS score on the side treated with Perlane-L (confidence interval was 86.1 to 99.0).
At 15 minutes post injection, 56.7% still had a within-patient difference in VAS of at least 10 mm.

Patients were randomized to either Perlane or Hylaform in a “within-patient” model of augmentation correction of bilateral nasolabial folds (NLFs) with one treatment assigned to one side and the other treatment to the other side.
A touch-up was allowed 2 weeks after initial treatment.
Patients were partially masked; evaluating physicians were independent and masked; treating physicians were partially masked.
Effectiveness was studied with 6 months follow-up.
Safety was studied with 6 months follow-up.
Endpoints Effectiveness Primary The difference in effect of Perlane as compared to Hylaform on the visual severity of the NLFs, as assessed by a Blinded Evaluator at 6 months after baseline.
The primary evaluation parameter was a five-step validated Wrinkle Severity Rating Scale (WSRS) score (absent, mild, moderate, severe, extreme) by the Blinded Evaluator at 6 months.
Success was defined as maintaining at least a one point improvement of the NLF on the WSRS at 6 months after optimal correction was achieved.
The percent of successful NLFs after Perlane and control treatments were compared, as well as a within-patient matched analysis (McNemar's Test).
Secondary Wrinkle Severity Rating Scale (WSRS) was assessed at other follow-up points (2 weeks and 3, 4.5, and 6 months after optimal correction) by the Blinded Evaluator and the patient.
Global Aesthetic Improvement (GAI): very much improved /much improved / improved / no change / worse, assessed at same time points by patient.
Safety assessments included: investigator evaluation of adverse events at all time points.
Outcomes Demographics The study enrolled 150 patients with moderate to severe nasolabial fold wrinkles.
The patients were predominantly healthy white females.
The study was completed by 140 of 150 patients at six months and additional safety data were available in 122 of 150 patients at 9 months.
Gender – Female: 140 (93%); Male: 10 (7%) Ethnicity – White: 142/150 (95%); Non-caucasian: 8/150 (5%) Efficacy The results of the blinded evaluator assessments are presented in Table 13 and are based on an Intentto- Treat (ITT) analysis.
At 6 months, 113/150 (75%) of the Perlane-treated NLFs maintained at least a single point improvement on the WSRS compared to 57/150 (38%) of the control-treated NLFs.

Drug Description Perlane-L® (non-animal stabilized hyaluronic acid) Injectable Gel with 0.3% Lidocaine Caution: Federal Law restricts this device to sale by or on the order of a physician or licensed practitioner.
DESCRIPTION Perlane-L is a sterile gel of hyaluronic acid generated by Streptococcus species of bacteria, chemically cross-linked with BDDE, stabilized and suspended in phosphate buffered saline at pH=7 and concentration of 20 mg/mL with 0.3% lidocaine.
The median particle size is between 750 and 1000 microns.
Indications & Dosage INDICATIONS Perlane-L is indicated for implantation into the deep dermis to superficial subcutis for the correction of moderate to severe facial folds and wrinkles, such as nasolabial folds.
DOSAGE AND ADMINISTRATION Directions for Assembly Assembly of 27 G TW and 29 G TW needle to syringe Use the thumb and forefinger to hold firmly around both the glass syringe barrel and the Luer-Lok adapter.
Grasp the needle shield with the other hand.
To facilitate proper assembly, both push and rotate firmly.
Pre-treatment Guidelines Prior to treatment, the patient should avoid taking aspirin, nonsteroidal anti-inflammatory medications, St.
John's Wort, or high doses of Vitamin E supplements.
These agents may increase bruising and bleeding at the injection site.
Treatment Procedure 1.
It is necessary to counsel the patient and discuss the appropriate indication, risks, benefits and expected responses to the Perlane-L treatment.
Advise the patient of the necessary precautions before commencing the procedure.
A consent form should be utilized.
2.
Assess the patient's need for appropriate anesthetic treatment for managing comfort, i.e., topical anesthetic, local or nerve block.
3.
The patient's face should be washed with soap and water and dried with a clean towel.
Cleanse the area to be treated with alcohol or another suitable antiseptic solution.
4.
Sterile gloves are recommended while injecting Perlane-L.
5.
Before injecting, press rod carefully until a small droplet is visible at the tip of the needle.
6.
Perlane-L is administered using a thin gauge needle (27 G TW x ½” or 29 G TW x ½”).
The needle is inserted at an approximate angle of 30° parallel to the length of the wrinkle or fold.
Perlane-L should be injected into the deep dermis to superficial layer of the subcutis.
If Perlane-L is injected too superficially this may result in visible lumps and/or bluish discoloration.
7.
Inject Perlane-L applying even pressure on the plunger rod.
It is important that the injection is stopped just before the needle is pulled out of the skin to prevent material from leaking out or ending up too superficially in the skin.
8.
Only correct to 100% of the desired volume effect.
Do not overcorrect.
With cutaneous deformities the best results are obtained if the defect can be manually stretched to the point where it is eliminated.
The degree and duration of the correction depend on the character of the defect treated, the tissue stress at the implant site, the depth of the implant in the tissue and the injection technique.
9.
Typical usage for each treatment session is specific to the site as well as wrinkle severity.
In a prospective study of midface wrinkle correction, the median total dose was 3.0 mL.
Based on U.S.
clinical studies, the maximum recommended dose per treatment is 6.0 mL.
Injection Techniques 1.
Perlane-L can be injected by a number of different techniques that depend on the treating physician's experience and preference, and patient characteristics.
2.
Serial puncture (A) involves multiple, closely spaced injections along wrinkles or folds.
Although serial puncture allows precise placement of the filler, it produces multiple puncture wounds that may be undesirable to some patients.
3.
Linear threading (B) is accomplished by fully inserting the needle into the middle of the wrinkle or fold and injecting the filler along the track as a “thread.” Although threading is most commonly practiced after the needle has been fully inserted and is being withdrawn, it can also be performed while advancing the needle (“push-ahead” technique).
4.
Serial threading is a technique that utilizes elements of both approaches.
5.
Cross-hatching (C) consists of a series of parallel linear threads injected at intervals of five to ten mm followed by a new series of threads injected at right angles to the first set to form a grid.
This technique is particularly useful in facial contouring when coverage of the treatment region needs to be maximized.
A.
Serial Puncture B.
Linear Threading C.
Cross-hatching 6.
Note! The correct injection technique is crucial for the final result of the treatment.
Dissection of the sub-epidermal plane with lateral movement of the needle, rapid flows ( > 0.3 mL/min), rapid injection or high volumes may result in an increase in short-term episodes of bruising, swelling, redness, pain, or tenderness at the injection site.
7.
When the injection is completed, the treated site should be gently massaged so that it conforms to the contour of the surrounding tissues.
If an overcorrection has occurred, massage the area firmly between your fingers or against an underlying superficial bone to obtain optimal results.
8.
If so called “blanching” is observed, i.e., the overlying skin turns a whitish color, the injection should be stopped immediately and the area massaged until it returns to a normal color.
9.
If the wrinkle needs further treatment, the same procedure should be repeated until a satisfactory result is obtained.
Additional treatment with Perlane-L may be necessary to achieve the desired correction.
10.
If the treated area is swollen directly after the injection, an ice pack can be applied on the site for a short period.
Ice should be used with caution if the area is still numb from anesthetic to avoid thermal injury.
11.
Patients may have mild to moderate injection site reactions, which typically resolve in a few days.
Sterile Needle(s) Follow national, local or institutional guidelines for use and disposal of medical sharp devices.
Obtain prompt medical attention if injury occurs.
To help avoid needle breakage, do not attempt to straighten a bent needle.
Discard it and complete the procedure with a replacement needle.
Do not reshield used needles.
Recapping by hand is a hazardous practice and should be avoided.
Discard unshielded needles in approved sharps collectors.
Perlane-L is provided with a needle that does not contain engineered injury protection.
Administration of Perlane-L requires direct visualization and complete and gradual insertion of the needle making engineered protections infeasible.
Care should be taken to avoid sharps exposure by proper environmental controls.

Overdosage & Contraindications Side Effects & Drug Interactions SIDE EFFECTS Adverse Experiences There were five U.S.
studies that reported adverse events.
In two U.S.
studies (i.e., Study MA-1400-01 and Study MA-1400-02) involving 433 patients at 25 centers, the adverse outcomes reported in patient diaries during 14 days after treatment are presented in Tables 1–4.
The physician diagnosed adverse events identified in these studies at 72 hours after injection are presented in Table 7.
In Study MA-1400-01, 150 patients were injected with Perlane on one side of the face and Restylane® on the other side of the face.
In study MA-1400-02, 283 patients were randomized to receive either Perlane or Restylane injection on both sides of the face.
Table 8 presents all investigatoridentified adverse events recorded at study visits 2 weeks or more after injection in studies MA-1400- 01, MA-1400-02, 31GE0101 and 31GE0002.
In Study 31GE0101, 150 Canadian patients were injected with both Perlane and Hylaform.® In Study 31GE0002, 68 Scandinavian patients underwent both Perlane and Zyplast® injections.
In a fifth U.S.
study (Study MA-1400-03) 60 patients at three centers randomly received Perlane-L injections on one side of the face and Perlane injections on the other side of the face.
The adverse events reported in patient diaries during 14 days after treatment are presented in Tables 5 and 6.
The physician-recorded adverse events identified in study MA-1400-03 at 14 days after injection are presented in Table 9.
Table 7 shows the number of adverse events identified by investigators at 72 hours after injection for Studies MA-1400-01 and MA-1400-02.
Some patients had multiple adverse events or had the same adverse event at multiple injection sites.
No adverse events were of severe intensity.
Table 8 presents the number of patients and per patient incidence of all adverse events identified by investigators at visits occurring two or more weeks after injection.
In two studies (i.e., 31GE0101 and 31GE0002) with repeat administration of Perlane at 6–9 months following the initial correction, the incidence and severity of adverse events were similar in nature and duration to those recorded during the initial treatment sessions.
In all four studies, investigators reported the following local and systemic events that were judged unrelated to treatment and occurred at an incidence of less than 1%, i.e., acne; tooth disorders (e.g., pain, infection, abscess, fracture); dermatitis (e.g., rosacea, unspecified, contact, impetigo, herpetic); unrelated injection site reactions (e.g., desquamation, rash, anesthesia); facial palsy with co-administration of botulinum toxin; headache/migraine; nausea (with or without vomiting); syncope; gastroenteritis; upper respiratory or influenza-like illness; bronchitis; sinusitis; pharyngitis; otitis; viral infection; cystitis; diverticulitis; injuries; lacerations; back pain; rheumatoid arthritis; and various medical conditions such as chest pain, depression, renal stones, and uterine fibroids.
Table 9 shows the number of adverse events identified by investigators during Day 1 through Day 14 after injection in Study MA-1400-03.
Study MA-1400-03, included 47 subjects who had no prior cosmetic treatment and 13 subjects who had prior dermal filler treatment.
There were no statistical differences in the proportion of subjects with adverse events who had prior treatment and those with no prior treatment.
Post Marketing Surveillance The following adverse events were received from post-marketing surveillance for Restylane and Perlane in the U.S.
and other countries: presumptive bacterial infections, inflammatory adverse events, necrosis, injection site numbness/tingling, and vasovagal reactions.
Reported treatments have included systemic steroids, systemic antibiotics, and intravenous administrations of medications.
Additionally, delayed inflammatory reaction to Restylane has been observed with swelling, redness, tenderness, induration and rarely acneform papules at the injection site with onset as long as several weeks after the initial treatment.
Average duration of these effects is two weeks.
Implant and injection site reactions, mostly non-serious events, have also been reported.
These include: discoloration, bruising, swelling, mass formation, erythema, pain, scarring and ischemia.
Most instances of discoloration including hyperpigmentation, sometimes described as a blue or brown color and ranging from mild to severe, have occurred within the same day as treatment but have also occurred up to 6 months post treatment.
These events typically resolve within a few days but with some infrequent instances lasting up to 18 months.
Implant and/or injection site bruising, swelling, erythema and pain generally occurred on the same day as treatment usually resolving within 1 to 4 weeks.
Some occurrences have persisted for up to 6 months.
Severity for these events is generally mild to moderate although some cases have been severe.
Mild to moderate mass formations (typically described as lumps or bumps) have also been seen ranging in onset from 1 day to 6 months post implantation.
Rarely, events of this type have been observed for up to 13 months.
These events usually resolved within 1 to 5 months.
Mild to moderate scarring was rarely observed.
Onset of symptoms ranged from immediate post treatment to up to 1 year following implantation.
Symptom resolution was approximately 3 weeks with 1 instance lasting up to 3 years.
Most ischemic events have occurred immediately following implantation and ranged in severity from moderate to severe.
Events were resolving as early as 2 days and up to 9 weeks post treatment.
Symptoms associated with herpetic eruptions which included swelling, pain, whiteheads, vesicles and erythema have been reported and commonly occurred within 2 days to 1 month following implantation.
Severity ranged from mild to moderate and resolution of symptoms ranged from 1 to 15 weeks.
Telangiectasias and capillary disorders, commonly characterized as broken capillaries have been reported and occurred with an onset of 1 day to 7 weeks.
Most events ranged in severity from mild to moderate with a few severe instances.
Duration of events ranged from 2 weeks up to 13 months.
Very rarely, instances of moderate to severe biopsy confirmed granuloma were observed.
Onset ranged from 3 weeks to 4 months with resolution between 6 weeks to 11 months.
Events of mild to moderate hypoaesthesia have occurred ranging in onset from 1 day to 1 week.
Duration and resolution occurred between 1 day and 10 weeks.
Serious adverse events have been rarely reported.
The most commonly reported serious adverse events (by MedDRA Preferred Term) were hypersensitivity, and implant and/or injection site swelling, ischemia and discoloration.
Of these infrequently reported serious events, only one adverse event has occurred in a frequency of 5 or greater: Hypersensitivity reactions ranging from moderate to severe mostly occurred within 1 to 2 days of implantation and up to 3 weeks.
Reported symptoms included swelling; itching on chest and back; puffy, burning, watery, and itchy eyes; and shortness of breath.
Treatments included steroids, diphenhydramine, unspecified intravenous medication, oxygen and various creams.
An evaluation of patients who reported potential hypersensitivity reactions did not demonstrate any evidence of IgE or cell mediated immunologic reactions specifically directed at hyaluronic acid.
Most hypersensitivity events resolved within 1 to 14 days with or without treatment.
Adverse reactions should be reported to Medicis Aesthetics Inc.
at 1-866-222-1480.
