This clinical study is focused on kidney protection and immune balance for people with primary membranous nephropathy (PMN).
What’s the Purpose of the
AUTUMN Study?
The study aims to evaluate whether the study drug ALXN1920, compared to a placebo, can reduce symptoms in adults with PMN such as:
Excess protein in urine
Swelling
Risk of kidney function decline
Can I Participate?

You may be eligible to participate in this study if you:
Are between 18-75 years old
Have been diagnosed with primary membranous nephropathy (PMN)
Have high levels of protein in your urine [about 3.5 grams or more per day]
Are already on or able to receive standard-of-care therapy for PMN
You may not be eligible to participate in this study if you:
Have significant loss of kidney function
Have other kidney diseases or a history of kidney transplant

Other eligibility criteria apply and will be evaluated by a study doctor if you choose to continue with screening for the study.
Why Should I Join the
AUTUMN Study?
The study drug ALXN1920 aims to more specifically target and block the immune system in addition to currently used immunosuppressive drugs, potentially resulting in less protein in the urine and better kidney function preservation in adults with PMN.
By enrolling in this phase 2a study, you may receive:
Access to expert physicians with experience managing primary membranous nephropathy.
The ability to complete some of the study visits at home.
Insurance is not required to join this study.
Your participation supports the advancement of treatments for individuals with primary membranous nephropathy.

Frequently Asked Questions
Primary membranous nephropathy (PMN) is a rare autoimmune disease.
It happens when a component of the immune system, called the complement system, mistakenly attacks the kidney filters. These filters help clean the blood, so when they are damaged, the kidneys cannot work as well.

This is called proteinuria. People with PMN may notice foamy urine, swelling in the legs or around the eyes, tiredness, or side effects from medicines that lower the immune system.
Blood tests to look for an increase in antibodies called anti-PLA2R, which are found in many people with PMN.
Kidney biopsy to look at the kidney tissue under a microscope and confirm the diagnosis.
Urine tests to check how much protein is leaking into the urine and how well the kidneys are working.
Doctors can help manage symptoms with blood pressure medicines, diuretics, andsometimes with medication thatsuppressyour body’s immune system. Many people also make life style changes, such as lowering salt intake, maintaining a healthy diet, and staying active, to help support kidney health.
