PATIENT INFORMATION

PADCEV® (PAD-sev)

(enfortumab vedotin-ejfv)

for injection

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 the most important information I should know about PADCEV?

PADCEV may cause serious side effects, including:

Skin reactions. Skin reactions including severe skin reactions have happened in people treated with PADCEV and may be more common when PADCEV is given with pembrolizumab. In some cases, these severe skin reactions have caused death. Most severe skin reactions occurred during the first cycle of treatment but may happen later. Your healthcare provider will monitor you, may stop your treatment with PADCEV completely or for a period of time (temporarily), may change your dose, and may prescribe medicines if you get skin reactions. Tell your healthcare provider right away if you develop any of these signs of a new or worsening skin reaction:

•
target lesions (skin reactions that look like rings)
•
rash or itching that continues to get worse
•
blistering or peeling of the skin
•
painful sores or ulcers in mouth or nose, throat, or genital area
•
fever or flu-like symptoms
•
swollen lymph nodes

See “What are the possible side effects of PADCEV?” for more information about side effects.

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.
•
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:
o
have received PD-1 or PD-L1 immunotherapy medicine and chemotherapy that contains platinum, or
o
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.

Before receiving PADCEV, tell your healthcare provider about all of your medical conditions, including if you:

•
are currently experiencing numbness or tingling in your hands or feet
•
have a history of high blood sugar or diabetes
•
have liver problems
•
are pregnant or plan to become pregnant. PADCEV can harm your unborn baby. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with PADCEV.
 
Females who are able to become pregnant:
 
o
Your healthcare provider should do a pregnancy test before you start treatment with PADCEV.
o
You should use an effective method of birth control during your treatment and for at least 2 months after the last dose of PADCEV.
 
Males with a female sexual partner who is able to become pregnant:
 
o
If your female partner is pregnant, PADCEV can harm the unborn baby.
o
You should use an effective method of birth control during your treatment and for at least 4 months after the last dose of PADCEV.
•
are breastfeeding or plan to breastfeed. It is not known if PADCEV passes into your breast milk. Do not breastfeed during treatment and for 3 weeks after the last dose of PADCEV.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking PADCEV with certain other medicines may cause side effects.

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:
o
Each cycle is 21 days.
o
You will receive PADCEV on days 1 and 8 of every cycle.
•
If you receive PADCEV alone:
o
Each PADCEV cycle is 28 days.
o
You will receive PADCEV on days 1, 8, and 15 of every cycle.
•
Your healthcare provider will decide how many treatment cycles you need.
•
Your healthcare provider may do blood tests regularly during treatment with PADCEV.

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:
o
frequent urination
o
increased thirst
o
blurred vision
o
confusion
o
it becomes harder to control your blood sugar
o
drowsiness
o
loss of appetite
o
fruity smell on your breath
o
nausea, vomiting, or stomach pain
•
Lung problems. PADCEV may cause severe or life-threatening inflammation of the lungs that can lead to death. These severe problems may happen more often when PADCEV is given in combination with pembrolizumab. Tell your healthcare provider right away if you get new or worsening symptoms, including trouble breathing, shortness of breath, or cough.
•
Nerve problems. Nerve problems called peripheral neuropathy are common during treatment with PADCEV and can also sometimes be severe. Nerve problems may happen more often when PADCEV is given in combination with pembrolizumab. 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. 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.
•
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, blister, peeling skin, or discomfort at the infusion site.

Your healthcare provider may decrease your dose of PADCEV, or temporarily or completely stop your treatment with PADCEV if you get severe side effects.
