No cases of serious and fatal liver
injury have been observed with ROMVIMZA1
ROMVIMZA was associated with elevated liver enzymes1
Cases of serious and fatal liver injury have occurred with the use of another kinase inhibitor that targets CSF1R, pexidartinib1,2
Monitor liver tests, including AST, ALT, total bilirubin, direct bilirubin, ALP and gamma-glutamyl transferase (GGT), prior to initiation of ROMVIMZA, twice a month for the first two months and once every three months for the first year of therapy and as clinically indicated thereafter1
Across clinical trials in 253 patients treated with ROMVIMZA1
- Grade ≥3
AST2% - Grade ≥3
increased ALT1% - Grade ≥3 increased bilirubin0%
- Cases of serious or fatal liver injury0
Dose interruptions occurred in 2% and dose reductions occurred in 1% of patients due to AST/ALT increase. One patient discontinued therapy due to Grade 3 AST increased1
Avoid ROMVIMZA in patients with pre‑existing increased serum transaminases; total bilirubin or direct bilirubin (>ULN); or active liver or biliary tract disease, including ALP1
Isolated liver enzymes elevations and mixed or cholestatic hepatotoxicity are clinically distinct adverse events3,4
No cases of hair hypopigmentation were observed in the MOTION study5
No REMS program* required1
*Risk Evaluation and Mitigation Strategy (REMS) is a drug safety program that the Food and Drug Administration (FDA) can require for certain medications with serious safety concerns to help ensure the benefits of the medication outweigh its risks.
ALP=alkaline phosphatase; ALT=alanine aminotransferase; AST=aspartate aminotransferase; CSF1R=colony-stimulating factor 1 receptor; ULN=upper limit of normal.
