Interactions between your drugs
valoctocogene roxaparvovec vadadustat

Consumer information for this interaction is not currently available.
MONITOR: Coadministration with other hepatotoxic agents may increase the risk of liver injury and decrease the therapeutic efficacy of valoctocogene roxaparvovec, a liver-directed adeno-associated virus (AAV) vector designed to help replace missing coagulation factor VIII. Most of the patients treated with valoctocogene roxaparvovec in clinical studies experienced ALT elevations, presumably due to immune-mediated injury of transduced hepatocytes, which may decrease the therapeutic efficacy of valoctocogene roxaparvovec. In a clinical trial of adults with severe hemophilia (n=134) receiving a single dose of valoctocogene roxaparvovec (6 x 10[13] vector genomes [vg]/kg), 107 patients (96%) experienced increased ALT levels greater than or equal to 1.5 times baseline or greater than the upper limit of normal (ULN), while 12 patients (9%) experienced increased ALT levels greater than 5 to 20 times ULN. Some of the ALT elevations were associated with decreased factor VIII activity. Most patients treated with valoctocogene roxaparvovec required immunosuppressive medications, including corticosteroids, to control elevations in transaminases and prevent loss of transgene expression.
MANAGEMENT: The risk of additive hepatotoxicity and decreased therapeutic efficacy of valoctocogene roxaparvovec should be considered after coadministration with other hepatotoxic agents. Alternative treatment may be required if an interaction is suspected. Monitoring of ALT and factor VIII activity levels (e.g., weekly to every 2 weeks for the first month) is recommended when a new medication is started following valoctocogene roxaparvovec administration.
Drug and food interactions
valoctocogene roxaparvovec food
Applies to: valoctocogene roxaparvovec
After receiving valoctocogene roxaparvovec, alcohol consumption should be avoided for at least 1 year and limited thereafter. Valoctocogene roxaparvovec can cause liver problems, which may make the medication less effective in treating your condition. Consuming other substances that can also affect the liver such as alcohol after receiving valoctocogene roxaparvovec may increase that risk. Symptoms of liver problems include fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark urine, pale stools, and/or yellowing of the skin or eyes. Blood tests to monitor liver function should be performed before and after treatment with valoctocogene roxaparvovec. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
vadadustat food
Applies to: vadadustat
Consumer information for this interaction is not currently available.
MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.
MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.
