What side effects can Xeglyze (moxetumomab pasudotox-tdfk) cause?
Xeglyze can cause side effects related to blood pressure, blood clotting and capillary leak (fluid leaking from small blood vessels), as well as effects on blood counts and other organs. The most important risks to watch for include capillary leak syndrome and hemolytic uremic syndrome (HUS) [1].
What are the most serious warnings and how do they show up?
Key serious adverse effects include:
- Capillary leak syndrome: This can cause swelling, weight gain, and low blood pressure, and it can be life-threatening. Clinicians monitor closely during treatment [1].
- Hemolytic uremic syndrome (HUS): Signs can include reduced urination, fatigue, pallor, bruising, and abnormal kidney tests. This is treated as an emergency complication [1].
- Severe reactions during infusion or other acute systemic reactions can also occur; monitoring during administration is standard [1].
What side effects are common with Xeglyze?
Common side effects reported with this drug include nausea, fever, vomiting, fatigue, and infusion-related reactions [1]. (Exact frequencies can vary by study population and dosing schedule.)
What should patients tell their clinician right away during treatment?
Call the treating team urgently if any of the following occur during or shortly after infusions:
- Dizziness, fainting, or symptoms of low blood pressure
- Sudden swelling or rapid weight gain
- Decreased urination or signs of kidney trouble
- Unusual bruising or bleeding, or severe weakness
- Any severe infusion reaction symptoms (such as trouble breathing or severe reactions during the infusion) [1]
How are side effects managed?
Because the main serious risks involve capillary leak and HUS, management typically includes close monitoring of vital signs and labs during treatment, early recognition of symptoms, and prompt supportive care or treatment interruptions as needed [1].
Who is most at risk for severe side effects?
Risk can be higher for patients with baseline kidney issues or those who have already experienced prior serious toxicities, since HUS involves kidney injury. The treating team monitors labs and symptoms to reduce harm and decide whether to continue, adjust, or stop therapy [1].
