What is IgAN?

A chronic autoimmune kidney disease with serious impact

IgA nephropathy (IgAN) is a rare chronic disease in which B cells (a type of immune cell) produce abnormal antibodies that result in the formation of immune clusters. These clusters build up in the kidneys, causing them to become damaged and stop working properly.

Define:

abnormal antibodies antibodies immunoglobulin nephropathy

IgA=immunoglobulin A.

Two signals drive the immune activity responsible for kidney damage in IgAN

Two proteins called BAFF and APRIL act as signals that activate B cells

Activated B cells make different types of antibodies, including some abnormal ones

Illustration of multiple antibodies grouping together to form immune clusters

In IgAN, an autoimmune reaction to one of these abnormal antibodies results in the formation of immune clusters

When these clusters get stuck in the kidneys, inflammation and damage occur, leading to consequences such as proteinuria (protein in the urine), hematuria (blood in the urine), and a decline in kidney function

Define:

BAFF and APRIL B cell

APRIL=A proliferation-inducing ligand; BAFF=B-cell activating factor.

Possible symptoms of IgAN

While some people with IgAN may not have symptoms, others may notice:

Proteinuria, or protein in the urine (it may look bubbly or foamy)

Hematuria, or blood in the urine (it may look pink, red, or brown)

Feeling tired

High blood pressure

Swelling in the feet, ankles, legs, and/or hands

Define:

proteinuria

IgAN progression isn’t always obvious

Because many people with IgAN have no symptoms, it may be easy for them to overlook the disease as it continues to worsen. Potential consequences of IgAN include:

Kidney inflammation

Irreversible kidney damage

Kidney failure

Dialysis

Kidney transplant

Increased risk of early death

INDICATION AND IMPORTANT SAFETY INFORMATION

What is TRUTAKNA?

TRUTAKNA (atacicept-vymj) is a prescription medicine used to reduce levels of protein in the urine (proteinuria) in adults with a kidney disease called primary immunoglobulin A nephropathy (IgAN), who are at risk of their disease getting worse.

It is not known if TRUTAKNA is safe and effective in children. 

TRUTAKNA is approved based on reduction of proteinuria. Continued approval may depend on results from an ongoing study to determine whether TRUTAKNA slows decline in kidney function.

IMPORTANT SAFETY INFORMATION

Who should not take TRUTAKNA?

Do not take TRUTAKNA if you are allergic to atacicept-vymj or any of the ingredients in TRUTAKNA. Get emergency help if you develop signs and symptoms of an allergic reaction, including:

breathing problems

swelling of the face, eyes, lips, tongue, or throat 

dizziness or lightheadedness 

itching

hives 

skin rash 

Before using TRUTAKNA, tell your doctor about all your medical conditions, including if you: 

have or think you have an infection or have infections that keep coming back.  

have recently received or are scheduled to receive an immunization (vaccine). TRUTAKNA may affect your immune system response to vaccines and increase your risk of an infection from live vaccines. 

You should be brought up to date with all vaccines before starting treatment with TRUTAKNA. 

You should not receive live vaccines within 30 days before starting or during treatment with TRUTAKNA. 

are pregnant or plan to become pregnant. It is not known if TRUTAKNA will harm your unborn baby. If you become pregnant during treatment with TRUTAKNA, you and your healthcare provider should call 1-833-633-8372. 

are breastfeeding or plan to breastfeed. It is not known if TRUTAKNA passes into your breastmilk. Talk to your healthcare provider about the best way to feed your baby if you take TRUTAKNA. 

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using TRUTAKNA with certain medicines may increase your risk of infections. 

What are the possible side effects of TRUTAKNA?
TRUTAKNA can cause serious side effects, including: 

Immunosuppression and increased risk of infections: TRUTAKNA weakens your immune system, which may increase your risk of infections. Your healthcare provider will check you for signs and symptoms of infections before you start and during treatment with TRUTAKNA. Tell your healthcare provider right away if you develop any signs or symptoms of infection, including:

fever

chills

feeling tired

cough

flu-like symptoms

aches and pains

warm, red, or painful skin

The most common side effects of TRUTAKNA include: upper respiratory tract infection and injection site reactions, such as redness, swelling, itching or skin irritation at the injection site. Your healthcare provider may interrupt treatment with TRUTAKNA if you have serious side effects. 

These are not all the possible side effects of TRUTAKNA. Call your doctor for medical advice about side effects. 

You may report side effects to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. You may also report side effects to Vera Therapeutics at 1-833-MED-VERA or medinfo@veratx.com.
