Summary
- This summary is based on the review of one systematic review/meta-analysis. [1]
- The adjusted hazard ratio (HR) (95% confidence interval (CI)) for overall survival (OS) when comparing avapritinib to midostaurin is 0.44 (95% CI: 0.25-0.76), indicating avapritinib may improve survival in patients with advanced systemic mastocytosis.
- The adjusted odds ratio (AOR) for overall response rate (ORR) for avapritinib versus midostaurin is 4.06 (95% CI: 3.09-5.33), suggesting a higher likelihood of treatment response with avapritinib.
- The adjusted odds ratio for complete remission (CR) for avapritinib compared to midostaurin is 9.56 (95% CI: 0.97-93.81), showing potential improvement in achieving complete remission with avapritinib, though the wide confidence interval indicates variability in the estimate.
- There is no safety information available in the reviewed studies.
