Why two NDCs? The FDA registers this code as 82194-510-02 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 82194-0510-02. Same drug, same package — only the format differs.

🩺 Clinical

Label name VYJUVEK GEL Ingredient Beremagene Geperpavec-Svdt
📖 What it is MedlinePlus · NLM

Beremagene geperpavec-svdt is used to treat certain adults and children 6 months of age or older who have dystrophic epidermolysis bullosa (an inherited disorder that causes the skin to be fragile leading to blisters, wounds, skin infections, and scarring). Beremagene geperpavec-svdt is in a class of medications called gene therapy. It works by replacing a gene that promotes wound healing by strengthening and stabilizing the skin.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo $23,033.88
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
Medicare Part B allowsASP · J3401 $1,032.437 / J3401 unit
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

About this product: this is a biologic. Biologics don't have small-molecule generics — competition comes from FDA-licensed biosimilars (shown above), not generics.
Where does this data come from?
Equivalents are other NDCs of the same ingredient, form and route from the openFDA NDC Directory, ranked least-expensive-first by NADAC. Therapeutic-equivalence (AB) ratings come from the FDA Orange Book; biologics use the FDA Purple Book for biosimilar & interchangeable status.

🧬Biologic — competition comes from biosimilars

Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through May 2035. This may affect when biosimilars become widely available, but it is not a guaranteed launch date.
📅 FDA approved May 19, 2023 ⏳ ~8.7 yr to latest listed protection

Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.

LOE
Biologic patent Exclusivity
🏛️Reference-product exclusivity
A flat 12 years of FDA market protection from first licensure. No biosimilar can be licensed before it ends — regardless of patents.
🧪Listed biologic patents
Patents the reference maker lists covering the molecule, formulation, or manufacturing. A biosimilar generally can’t launch until these resolve.
🔁Interchangeability
An interchangeable biosimilar may be substituted at the pharmacy (state laws vary). The first one can earn its own exclusivity period.
🛈 What do these terms mean?
Biologic patent
A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
Reference-product exclusivity
A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
Interchangeable exclusivity
The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
Earliest biosimilar (LOE)
The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.

Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

Common questions
Is there a biosimilar for VYJUVEK GEL?
No FDA-licensed biosimilar is currently listed for this biologic in the FDA Purple Book.
Why do different websites show different biosimilar dates?
Biosimilar availability isn’t based on one single date. Some sources use the reference-product exclusivity, some use the last listed patent, and patent litigation, settlements, and licenses can all change the real-world launch date. This page shows the underlying Purple Book dates so you can see why estimates differ.
Can a biosimilar launch before the last patent expires?
Sometimes. A biosimilar maker may settle with the reference manufacturer or receive a license to launch earlier. In other cases, the last listed protection delays competition.
What does “current Purple Book estimate” mean?
It means we’re using the latest patent and exclusivity dates currently listed in the FDA Purple Book. It is not a guaranteed launch date.
What does “FDA listed” mean?
It means the product appears in the FDA’s official directory. That’s a good sign a product exists for the U.S. market, but on its own it does not confirm a pharmacy can get it today. Where we have recent retail pricing data, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Purple Book for a patent or exclusivity on the reference biologic. It can affect when a biosimilar becomes widely available — but it is not a guaranteed launch date. Settlements and licenses can move the real date earlier or later.
Built from the FDA Purple Book Patent List (patents the reference-product sponsor has publicly listed under the BPCIA) plus reference-product exclusivity. Biosimilars cannot launch until these clear; patent litigation and settlements can shift the real date. Biologics have no small-molecule generics — competition comes from FDA-licensed biosimilars, not the Orange Book.
Where does this data come from?
Patents and exclusivity from the FDA Purple Book (biologics), refreshed from public FDA data. Biosimilar launch timing is an estimate, not a guarantee.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 82194-0510-02, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q1 2026 · 5 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Vyjuvek — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Vyjuvek. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 82194-510-02, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 82194-0510-02, written without dashes as 82194051002. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 82194-0510-02, the first segment (82194) is the labeler code FDA assigned to Krystal Biotech, Inc.; the middle segment (0510) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (02) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Krystal Biotech, Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Krystal Biotech, Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J3401 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

⚠️ Warnings and Cautions ~1 min read

5 WARNINGS AND PRECAUTIONS Accidental Exposure to VYJUVEK: Avoid direct contact with treated wounds and dressings of treated wounds until the next dressing change, following application. Clean the affected area if accidental exposure occurs. (5.1)

5.1Accidental Exposure to VYJUVEK Accidental exposure to VYJUVEK may occur to close contacts and caregivers. VYJUVEK is a genetically modified, herpes-simplex virus type 1 vector-based, replication-deficient, non-integrating gene therapy. VYJUVEK will not replicate in the patient’s cells and does not integrate into the patient cells’ native genetic material.

For precautions, Avoid direct contact with treated wounds (e.g., touching or scratching) and dressings of treated wounds until the next dressing change. Wear protective gloves when assisting patients with changing wound dressings and handling the disposal. In the event of an accidental exposure through a splash to the eyes or mucous membranes, flush with clean water for at least 15 minutes.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data described in this section reflects exposure to VYJUVEK gel in a randomized, intra-patient placebo‑controlled study. A total of 31 patients with dystrophic epidermolysis bullosa (DEB), including 30 patients with autosomal recessive DEB and one patient with autosomal dominant DEB received topical administration of VYJUVEK gel to their wounds.

The age of the patients ranged from 1 year to 44 years (mean age 17 years). Of the 31 patients, 19 (61%) were pediatric patients (less than 17 years of age), and 11 (36%) were females. Each patient received weekly topical application of VYJUVEK gel at one or more wound sites and placebo at a matching wound site as an intra-subject comparator.

The median duration of exposure to VYJUVEK gel was 25 weeks. The most frequent adverse reactions (incidence >5%) observed in the study are summarized in Table 3. There were no discontinuations due to adverse reactions.

🧬 Clinical Pharmacology ~2 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Dystrophic epidermolysis bullosa (DEB) is caused by mutation(s) in the COL7A1 gene, which results in reduced or absent levels of biologically active COL7. Upon topical application to the wounds, VYJUVEK can transduce both keratinocytes and fibroblasts. Following entry of VYJUVEK into the cells, the vector genome is deposited in the nucleus.

Once in the nucleus, transcription of the encoded human COL7A1 is initiated. The resulting transcripts allow for production and secretion of COL7 by the cell in its mature form. These COL7 molecules arrange themselves into long, thin bundles that form anchoring fibrils.

The anchoring fibrils hold the epidermis and dermis together and are essential for maintaining the integrity of the skin. Patients with autosomal dominant DEB (DDEB) have lower than normal functional anchoring fibrils, and patients with RDEB have no functional anchoring fibrils.

12.2Pharmacodynamics The pharmacodynamic activity (expression and localization of COL7 transgene) of VYJUVEK gel was demonstrated in an initial clinical study (n=6 patients). Linear deposition of the non-collagenous domain 1 (NC1) and domain 2 (NC2) of COL7 were observed at the dermal-epidermal junction in skin biopsies harvested after VYJUVEK treatment.

12.3Pharmacokinetics In an initial clinical study, viral vector DNA was detected in skin swab samples in all nine treated patients, with maximum level ranging from 5.1×10 4 to 4.1×10 8 vector genomes. In 6 out of 9 patients (67%), negative shedding was confirmed with three measurements below limit of detection within 8 weeks of treatment with VYJUVEK. No viral vector DNA was detected in blood or urine.

In the 31-patient randomized, double-blind, intra-patient placebo-controlled trial, systemic and potential environmental exposure assessments were conducted at weekly clinical site visits via quantification of VYJUVEK genomes in blood, urine, skin swabs, and bandage samples (vector shedding) using a validated qPCR assay, and detection of infectious viral particles in skin swabs (infectivity) using a validated plaque titer assay. All blood samples and all but one urine sample collected throughout the study were below the limit of detection.

Skin swabs from 19 of the 31 patients (61%) were positive for viral vector following treatment with VYJUVEK. Negative shedding from skin swabs was achieved in 16 of the 19 patients (84%) within six weeks following treatment with VYJUVEK. Most wound dressings (94%, 29/31) contained a range of detectable vector genomes.

However, no extracellular infectious particles were detected on the skin surface of any patient at any timepoint tested, after topical VYJUVEK application.

12.6Immunogenicity There was minimum potential for systemic exposure to VYJUVEK. Antibodies against the viral vector (HSV-1) and transgene protein (COL7) were evaluated in a subset of patients in the randomized, intra-patient placebo-‑controlled clinical study. A total of 64% of evaluated patients (14/22) were anti-HSV-1 antibody positive at baseline.

Six of the 8 anti-HSV-1 seronegative patients seroconverted by Week 26 following treatment with VYJUVEK. For patients with available matched baseline and end-of-study serum samples, anti‑drug antibodies (ADAs) to COL7 were detected in 72% (13/18) of patients treated with VYJUVEK for up to 26 weeks. Data are limited to perform correlative assessment on the impact of ADA on pharmacodynamic activity.
