PATIENT INFORMATION
Additions and/or revisions underlined:
If your healthcare provider prescribes PADCEV in combination with the medicines pembrolizumab or pembrolizumab and berahyaluronidase alfa-pmph, also read the Medication Guide that comes with these medicines for additional important information.
. . .
What is PADCEV?
PADCEV is a prescription medicine used to treat adults with bladder cancer and cancers of the urinary tract (renal pelvis, ureter, or urethra).
- PADCEV may be used with pembrolizumab or pembrolizumab and berahyaluronidase alfa-pmph before and after the surgical removal of your bladder when:
- your bladder cancer has spread into the muscle layer of the bladder (muscle invasive bladder cancer [MIBC]) but not to other parts of the body, and
- you are not able to receive chemotherapy that contains the medicine cisplatin.
- PADCEV may be used with pembrolizumab or pembrolizumab and berahyaluronidase alfa-pmph when your bladder or urinary tract cancer has spread or cannot be removed by surgery (locally advanced or metastatic).
- PADCEV may be used alone when your bladder or urinary tract cancer has spread or cannot be removed by surgery (locally advanced or metastatic) if you:
- have received PD-1 or PD-L1 immunotherapy medicine and chemotherapy that contains platinum, or
- are not able to receive a chemotherapy that contains cisplatin and you have received 1 or more prior therapies.
It is not known if PADCEV is safe and effective in children.
. . .
How will I receive PADCEV?
- PADCEV will be given to you by intravenous (IV) infusion into your vein over 30 minutes.
- PADCEV is given over periods of time called “cycles”.
- If you receive PADCEV with pembrolizumab or pembrolizumab and berahyaluronidase alfa-pmph:
- Each cycle is 21 days.
- You will receive PADCEV on days 1 and 8 of every cycle.
. . .
What are the possible side effects of PADCEV? PADCEV may cause serious side effects, including:
- See “What is the most important information I should know about PADCEV?”
- High blood sugar (hyperglycemia). An increase in blood sugar is common during treatment with PADCEV. Severe high blood sugar, a serious condition called diabetic ketoacidosis (DKA), and death have happened in people with and without diabetes, treated with PADCEV. Tell your healthcare provider right away if you get any symptoms of high blood sugar, including:
. . .
- Eye problems. Certain eye problems are common during treatment with PADCEV. Tell your healthcare provider right away if you get dry eyes, increased tearing, blurred vision, or any vision changes. You may use artificial tear substitutes to help prevent or treat dry eyes.
. . .
Your healthcare provider may decrease your dose of PADCEV, or temporarily or completely stop your treatment with PADCEV if you get severe side effects.

Two patients (0.3%) developed extravasation reactions with secondary cellulitis, bullae, or exfoliation. Ensure adequate venous access prior to starting PADCEV and monitor for possible extravasation during administration. If extravasation occurs, stop the infusion and monitor for adverse reactions.

As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the trials described below with the incidence of antibodies in other trials or other enfortumab vedotin-ejfv products may be misleading.
Following administration of PADCEV 1.25 mg/kg; 16/590 (2.7%) patients tested positive for anti-therapeutic antibody (ATA) against enfortumab vedotin-ejfv at one or more post-baseline time points. Due to the limited number of patients with ATA against enfortumab vedotin-ejfv, no conclusions can be drawn concerning a potential effect of immunogenicity on efficacy, safety or pharmacokinetics.
7 Drug Interactions
7.1 Effects of Other Drugs on PADCEV(Additions and/or revisions underlined)
Dual P-gp and Strong CYP3A4 Inhibitors
Concomitant use with dual P-gp and strong CYP3A4 inhibitors may increase unconjugated MMAE exposure
[see Clinical Pharmacology (12.3)], which may increase the incidence or severity of PADCEV toxicities. Closely monitor patients for signs of toxicity when PADCEV is given concomitantly with dual P-gp and strong CYP3A4 inhibitors.
8 Use in Specific Populations
8.5 Geriatric Use(Additions and/or revisions underlined)
Of the 680 patients treated with PADCEV in clinical trials, 440 (65%) were 65 years or older and 168 (25%) were 75 years or older. No overall differences in safety or effectiveness were observed between these patients and younger patients [see Clinical Pharmacology (12.3)].
(Additions and/or revisions underlined)
Avoid the use of PADCEV in patients with moderate or severe hepatic impairment (total bilirubin >1.5 x ULN and AST any). PADCEV has only been studied in a limited number of patients with moderate hepatic impairment (n=3) and has not been evaluated in patients with severe hepatic impairment [see Clinical Pharmacology (12.3)]. In another ADC that contains MMAE, the frequency of > or equal to Grade 3 adverse reactions and deaths was greater in patients with moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment compared to patients with normal hepatic function. No adjustment in the starting dose is required when administering PADCEV to patients with mild hepatic impairment (total bilirubin 1 to 1.5 × ULN and AST any, or total bilirubin < or equal to ULN and AST >ULN).

5 Warnings and Precautions
5.1 Skin Reactions(Newly added section)
Severe cutaneous adverse reactions, including fatal cases of Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) occurred in patients treated with PADCEV. SJS and TEN occurred predominantly during the first cycle of treatment but may occur later.
Skin reactions occurred in 54% of the 310 patients treated with PADCEV in clinical trials. Twenty-six percent (26%) of patients had maculopapular rash and 30% had pruritus. Grade 3-4 skin reactions occurred in 10% of patients and included symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), dermatitis bullous, dermatitis exfoliative, and palmar-plantar erythrodysesthesia. In study EV-201, the median time to onset of severe skin reactions was 0.8 months (range: 0.2 to 5.3). Of the patients who experienced rash, 65% had complete resolution and 22% had partial improvement. [see Adverse Reactions (6.2)].
Monitor patients closely throughout treatment for skin reactions. Consider topical corticosteroids and antihistamines, as clinically indicated. Withhold PADCEV and consider referral for specialized care for severe (Grade 3) skin reactions, suspected SJS or TEN. Permanently discontinue PADCEV in patients with confirmed SJS or TEN; or Grade 4 or recurrent Grade 3 skin reactions [see Dosage and Administration (2.2)].
6 Adverse Reactions
(Additions and/or revisions underlined)
The following serious adverse reactions are described elsewhere in the labeling:
Skin Reactions [see Warnings and Precautions (5.1)]
(Newly added section)
The following adverse reactions have been identified during post-approval use of PADCEV. 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 exposure.
Skin and subcutaneous tissue disorders: Epidermal necrosis, Stevens-Johnson syndrome, toxic epidermal necrolysis [see Warnings and Precautions (5.1)].

Patient Counseling Information(Newly added information)
Skin Reactions
Inform patients that severe skin reactions including SJS and TEN with fatal outcomes have occurred after administration of PADCEV, predominantly during the first cycle of treatment but may occur later. Advise patients to contact their healthcare provider immediately if they develop new target lesions, progressively worsening skin reactions, severe blistering or peeling of the skin [see Warnings and Precautions (5.1)].
(Additions and/or revisions underlined)
• Skin reactions. Severe skin reactions have happened after treatment with PADCEV, in some cases severe skin
reactions have caused death. Most severe skin reactions occurred during the first cycle (28 days) of treatment but
may happen later. Tell your healthcare provider right away if you develop any of these signs of a new or worsening
skin reaction:
o target lesions (skin reactions that look like rings)
o rash or itching that continues to get worse
o blistering or peeling of the skin
o painful sores or ulcers in mouth or nose, throat, or
genital area
o fever or flu-like symptoms
o swollen lymph nodes
Peripheral neuropathy. You may develop nerve problems called peripheral neuropathy during treatment with
PADCEV. Tell your healthcare provider right away if you get new or worsening numbness or tingling in your hands or
feet or muscle weakness.
• Eye problems. You can develop certain eye problems during treatment with PADCEV. Tell your healthcare provider
right away if you have dry eyes, or blurred vision. You may use artificial tear substitutes to help prevent or treat dry
eyes.
• Leakage of PADCEV out of your vein into the tissues around your infusion site (extravasation). If PADCEV
leaks from the injection site or the vein into the nearby skin and tissues, it could cause an infusion site reaction. These
reactions can happen right after you receive an infusion, but sometimes may happen days after your infusion. Tell
your healthcare provider or get medical help right away if you notice any redness, swelling, itching, or discomfort at
the infusion site.
The most common side effects of PADCEV include:
• tiredness (fatigue)
