FULL PRESCRIBING INFORMATION: CONTENTS*
LAVIVTM is an autologous cellular product indicated for improvement of the appearance of moderate to severe nasolabial fold wrinkles in adults.
The safety and efficacy of LAVIV for areas other than the nasolabial folds have not been established.
The efficacy of LAVIV beyond six months has not been established.
For autologous intradermal injection only
Only healthcare providers who have completed a Fibrocell-approved training program should administer LAVIV.
Inject LAVIV at 0.1 milliliter per linear centimeter into the nasolabial fold wrinkles. The recommended treatment regimen is three treatment sessions, administering up to 2 milliliters (2 vials) of LAVIV per session, at 3-6 week intervals.
A single vial of LAVIV contains approximately 18 million autologous fibroblasts in a 1.2 milliliters suspension, sufficient to administer 1 milliliter of product.
If LAVIV is administered to a patient who is not the individual whose skin was used to produce the LAVIV, serious immunological reactions can occur. Each vial of LAVIV has a unique patient identifier to assist in ensuring that there is no mismatch.
Serious hypersensitivity reactions, including anaphylaxis, can occur in patients with known hypersensitivity to the ingredients in LAVIV. Do not use LAVIV in patients allergic to gentamicin, amphotericin, dimethyl sulfoxide (DMSO), or material of bovine origin.
Injecting LAVIV into areas with skin infections can lead to local or systemic infection.
Hypersensitivity reactions have occurred in patients treated with LAVIV.
Injection-site bleeding and bruising can occur in patients treated with LAVIV. Patients taking aspirin, non-steroidal anti-inflammatory drugs (NSAIDS) or anticoagulants, as well as patients with coagulopathies, have a greater risk of severe bleeding or bruising. [See Drug Interactions (7)]
Leukocytoclastic vasculitis has occurred following treatment with LAVIV. [See Adverse Reactions (6.1)]
Chemotherapeutic drugs may interfere with the function of LAVIV. Patients with malignancies requiring ongoing therapy should not use LAVIV. Furthermore, patients undergoing chemotherapy are often immunosuppressed, and therefore may be at increased risk of infection following the use of LAVIV. [See Immunosuppression (5.8)]
A case of basal cell carcinoma was reported near the injection site seven months following LAVIV treatment in clinical trials. While the etiology of the case is uncertain, LAVIV is not recommended for patients with a known history of skin cancer.
The use of LAVIV requires three post-auricular skin biopsies and multiple injections in the nasolabial folds. These procedures traumatize the skin and may lead to keloid or hypertrophic scar formation in susceptible individuals. While excessive scarring or keloid formation was not observed in either the post-auricular biopsy or the injected areas during the clinical trials, the study population included only four African-American subjects, and Fitzpatrick skin types were not recorded. LAVIV is not recommended for patients with a known history of keloids or hypertrophic scarring.
Disorders affecting dermal fibroblasts, formation of normal collagen matrices, or other skin components may cause an abnormal response to LAVIV. Thus, LAVIV is not recommended for patients with such genetic disorders as Ehlers-Danlos syndrome, achondroplasia, osteogenesis imperfecta, epidermolysis bullosa, Marfan syndrome, and ataxia-telangiectasia.
Patients with active autoimmune disease or patients on immunosuppressant therapies may be more susceptible to infection and have difficulty healing following the use of LAVIV. LAVIV is an autologous cell product, and the safety and efficacy of LAVIV in patients with autoimmune disease are unknown.
Patients undergoing the treatment procedures associated with LAVIV are not routinely tested for adventitious viruses. Therefore, healthcare providers should employ universal precautions when handling LAVIV or biopsy material.
LAVIV is shipped following a passing sterility test result for cryopreserved bulk material (Drug Substance) and a negative Gram stain test result on the final LAVIV drug product. Full sterility test results are not available for the LAVIV drug product prior to treatment for up to 14 days. If microbial contamination is detected after the product has been shipped, Fibrocell will notify the health care providers and recommend appropriate actions.
The most common adverse reactions, occurring in ≥1% of subjects in clinical trials, were injection-site reactions, including redness, bruising, swelling, pain, hemorrhage, edema, nodules, papules, irritation, dermatitis, and pruritus.
Adverse reactions occurring in less than 1% of trial subjects were acne, facial or eyelid edema, hypersensitivity or decreased skin sensation at the injection site, post-procedural discomfort (headache, toothache, and jaw pain), herpes labialis, hyperpigmentation at the injection site, injection-site ischemia, basal cell cancer, and leukocytoclastic vasculitis.
Because clinical trials are conducted under widely varying conditions, adverse reactions observed in the clinical trials of a product cannot be directly compared to rates in the clinical trials of another product and may not reflect the rates observed in practice.
The overall clinical trial safety database for LAVIV includes 508 subjects who received at least one treatment of LAVIV and 354 subjects who received a vehicle-control in seven clinical trials for treatment of facial wrinkles (a skin biopsy study is described separately). This total safety population included patients aged 20 to 79 years, of whom 92% were female and 92% were White. The average duration of observation in the safety population was approximately 12 months.
An integrated summary of the adverse reactions from the seven clinical trials is presented in Table 1. More than 80% of all adverse reactions were local and required no treatment. Eighty-six percent of all injection-site adverse reactions resolved within one week.
The adverse reactions to the vehicle (Table 1) should not be viewed as adverse reactions to a placebo but rather as reactions to a non-cellular component of LAVIV, or to the injection procedure, or to both.

Adverse reactions occurring in fewer than 1% of trial subjects were acne, facial or eyelid edema, hypersensitivity or decreased skin sensation at the injection site, post-procedural discomfort (headache, toothache, and jaw pain), herpes labialis, hyperpigmentation at the injection site, injection-site ischemia, basal cell cancer, and leukocytoclastic vasculitis. In the skin biopsy study (described below), one subject was hospitalized for leukocytoclastic vasculitis, with lesions on his legs and trunk appearing nine days after product administration in his upper arm. These lesions resolved within 35 days after onset.
Skin Biopsy Study
A skin biopsy study was conducted to observe tissue responses and adverse reactions to LAVIV at the histological level. Twenty-nine subjects who had participated in a prior clinical trial of LAVIV, and who had sufficient quantities of autologous fibroblasts remaining, received up to three treatments of LAVIV in their upper arms at five-week intervals. Seven subjects received three treatments; 21 received two treatments; and one received only one treatment. Saline injections and non-treated areas in the contralateral arm were used as controls. The dose of LAVIV used in the skin biopsy study was the same as in the clinical trials (0.1 milliliter per linear centimeter of skin). The subjects and the two independent histopathology evaluators were blinded to treatment at each skin area.
Biopsies were taken from LAVIV- and saline-treated sites at 3 and 6 months after the last injection. Biopsies from untreated sites were taken only at 3 months. Histological evaluation was performed for all 29 subjects. At 3 months, histological examination showed inflammatory cell infiltration in 50% of LAVIV-treated sites as compared with 7% of placebo-treated or untreated sites. At 6 months, inflammatory cell infiltration was seen in 27% of the LAVIV-treated sites compared with 12% of placebo-treated sites. In all 29 subjects, there was no histological evidence of abnormal fibroblasts, significant scar formation, or abnormal organization of the extracellular matrix. There were no observed differences in epidermal/dermal thickness or cellularity between LAVIV-injected and placebo-injected skin samples.
No drug interaction studies have been performed with LAVIV.
Patients taking aspirin, NSAIDS or anticoagulants may experience increased bruising or bleeding at biopsy and/or injection sites. Concomitant use of aspirin, NSAIDs or anticoagulants is not recommended. Decisions regarding continued use or cessation of anticoagulants should be made in consultation with the health care provider.
Pregnancy Category C. Animal reproduction studies have not been conducted with LAVIV. It is also unknown whether LAVIV can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. LAVIV should be used in a pregnant woman only if clearly needed.
Clinical studies of LAVIV did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. [See Clinical Studies (14)]
LAVIV is an autologous cellular product composed of fibroblasts suspended in Dulbecco's Modified Eagle's Medium (DMEM) without phenol red. Dermal fibroblasts from post-auricular skin biopsy tissue are aseptically expanded using standard tissue-culture procedures until sufficient cells for three doses are obtained. Cells are then cryopreserved in a protein-free solution containing DMSO. When the patient administration is scheduled, cells are thawed, washed, and shipped to the clinic. A final sterility test is initiated prior to shipping, but the result will not be available for up to 14 days. A passing sterility culture result from the test performed on the cryopreserved bulk material (Drug Substance) and a negative Gram stain test result on the final LAVIV drug product are required for release of a product for shipping.
The effectiveness of LAVIV was demonstrated in two identically-designed, multi-center, randomized, double-blind, vehicle-controlled studies. The study population consisted of subjects with moderate to severe bilateral nasolabial fold wrinkles. A total of 421 subjects, aged 23 to 81 years, were randomized to receive LAVIV (n=210) or vehicle-control (n=211). In both studies, the major demographic features were similar between LAVIV and vehicle-control groups. Subjects in Study One (n=203) were predominantly female (90%), White (95%), and had an overall mean age of 56.7 years. Subjects in Study Two (n=218) were predominantly female (91%), White (89%), and had an overall mean age of 54.6 years.
Each subject underwent three post-auricular skin punch biopsies to obtain skin tissue to generate LAVIV. Subjects whose biopsy samples met acceptance criteria were randomized in a 1:1 ratio to receive either LAVIV or vehicle-control (DMEM without phenol red). Biopsy samples for subjects assigned to receive LAVIV were provided to the manufacturer for culture and processing. The process for production of LAVIV takes approximately 11 to 22 weeks. Study agent (either LAVIV or vehicle-control) was then administered intradermally to nasolabial fold wrinkles on both sides of the face at a dose of 0.1 milliliter per linear centimeter, up to 2 milliliters (1-2 x107 cells/milliliter) per each treatment session. A total of three separate treatment sessions occurred at intervals of 5±1 weeks.
Since LAVIV must be grown from subjects' own skin biopsies, the manufacturing process may not yield sufficient quantities of fibroblasts. Due to product manufacturing failure, 6.2% of subjects randomized to receive LAVIV in the two trials did not receive any LAVIV. In addition, 5.7% of subjects randomized to receive LAVIV had insufficient quantities of LAVIV to complete the planned three treatment sessions. A repeat biopsy was required in 1.5% of subjects as a result of shipping errors.
For both clinical trials, the co-primary efficacy outcomes were the proportion of subjects with a two-point improvement from baseline in the appearance of the nasolabial fold wrinkles at six months after the third treatment session. The outcomes were assessed with live evaluations performed independently by subjects and by evaluating physicians. Both subjects and evaluators were blinded to treatment assignment. To maintain the blinding, the injector and evaluator for any given subject were different investigators. Subjects assessed their nasolabial fold wrinkles on a five-point Subject Wrinkle Assessment scale that ranged from -2 to +2. The evaluating physicians used a six-point Evaluator Wrinkle Severity Assessment scale that ranged from 0 to 5 (Lemperle scale). Evaluation with the Lemperle scale was aided by a photoguide, which correlated wrinkle appearance with a specific numerical score.
Table 2 shows the efficacy results based on the intent-to-treat population, which included all randomized subjects. When subjects assessed themselves, 57% (Study One) and 45% (Study Two) of subjects receiving LAVIV achieved a 2-point improvement in the appearance of their nasolabial fold wrinkles compared with 30% (Study One) and 18% (Study Two) of subjects receiving vehicle-control. When assessed by evaluating physicians, 33% (Study One) and 19% (Study Two) of subjects receiving LAVIV achieved a 2-point improvement in their nasolabial fold wrinkles, compared with 7% of subjects receiving vehicle-control in both trials.
Efficacy beyond six months after the third administration has not been established. No clinical studies have been conducted to evaluate the efficacy of repeating treatment(s) beyond six months.
*The comparison of LAVIV vs. vehicle-control is based on Cochran-Mantel-Haenszel test stratified by study site.
|Clinical Studies||Subject Wrinkle Assessment||Physician Wrinkle Assessment|
|Study One||57% (57/100)||30% (31/103)||0.0001||33% (33/100)||7% (7/103)||< 0.0001|
|Study Two||45% (50/110)||18% (19/108)||< 0.0001||19% (21/110)||7% (8/108)||0.0075|
Clinical studies did not include sufficient numbers of subjects aged 65 years and older to determine whether their responses to LAVIV treatment differ from those of younger subjects. Of the 421 subjects in the two efficacy trials, 71 (17%) were ≥ 65 years old. The overall responder rates in geriatric subjects were lower and less consistent than in subjects younger than 65 years of age.
LAVIV is intended solely for autologous use.
LAVIV is supplied in two vials, each containing approximately 18 million cells in 1.2 milliliters. The vials are packaged together in a tamper-evident biohazard bag and shipped at 2-8°C (36-46°F) inside a temperature-controlled shipping container.
The manufacturing process for LAVIV takes approximately 11-22 weeks after receipt of the patient's biopsy samples by the manufacturer. Fibrocell will notify the clinic when each patient's treatment may be scheduled.

FDA-Approved Patient Labeling
This leaflet is designed to help you understand LAVIVTM. This leaflet does not take the place of talking with your healthcare provider about LAVIV. If you have questions about LAVIV, talk to your healthcare provider.
What is the most important information I should know about LAVIV?
LAVIV is made especially for you from your own skin cells. Your healthcare provider will check to see that the cells that come back from the manufacturer are yours. Using someone else's cells can cause a serious reaction. Do not let anyone else use your LAVIV.
The process for making LAVIV uses antibiotics (amphotericin and gentamicin), bovine serum (from cattle), and dimethyl sulfoxide (DMSO). If you are allergic to any of these, tell your healthcare provider.
Do not use LAVIV if you have a skin infection on your face because LAVIV treatment can make the infection worse. Talk to your healthcare provider if you have any other infection.
What is LAVIV?
LAVIV is made from your own skin cells, which are used to improve the appearance of wrinkles that go from the sides of your nose to the corners of your mouth (called nasolabial folds). LAVIV is injected into your face using a small needle.
Who should not get LAVIV?
You should NOT get LAVIV if you have any of the following problems or conditions:
What should I tell my healthcare provider before getting LAVIV?
Your health care provider will help you to decide whether you are a candidate for LAVIV and may help you avoid some of the adverse reactions from LAVIV. Before getting LAVIV, tell your healthcare provider if you have any of the following medical problems:
How will I get LAVIV?
Your healthcare provider will take three small skin samples (called biopsies) from behind your ears and send them to the manufacturer. Certain cells, called fibroblasts, are grown from the samples. This takes about three to six months.
The cells (LAVIV) are sent back to your healthcare provider, who will inject them into your nasolabial fold wrinkles using a small needle.
You usually get LAVIV in three treatment sessions about 3-6 weeks apart.
It is very important that you arrive on time for your treatment sessions. If you miss a treatment session, your LAVIV cells will expire and must be thrown out. Your healthcare provider will work with you to schedule a new treatment session.
There is a chance that your skin samples will not make enough cells to use. In this case, your doctor may ask you if you wish to try biopsy again.
What should I avoid while I am getting LAVIV treatments?
Tell your healthcare provider about all the medicines you take, including prescription and nonprescription drugs (like aspirin, vitamins, and dietary supplements). Your healthcare provider will advise you about the use of these medicines during LAVIV treatment.
Expect some redness, swelling, puffiness, pain or bruising following LAVIV treatments. You can help yourself by doing the following:
What are the possible or reasonably likely side effects of LAVIV?
The most common side effects are at the injection-site, including
Tell your healthcare provider or call the emergency department right away if you have
These are not all the possible side effects of LAVIV. Tell your health provider about any side effects that concern you. You may report side effects to FDA at 1-800-FDA-1088.
What are the ingredients in LAVIV?
LAVIV is made from your own skin cells placed in a mixture of water and salts.
Antibiotics (amphotericin and gentamicin), bovine serum (from cattle) and dimethyl sulfoxide (DMSO) are used during processing. Trace amounts of these ingredients may be present in LAVIV.
