  • Ruxolitinib (Jakafi) is a selective inhibitor of Janus Kinase 1 and 2, used for treating myelofibrosis, polycythemia vera, and steroid-refractory acute and chronic graft-versus-host disease in both adult and pediatric patients aged 12 years or older.
  • Analysis was based on 11 systematic reviews/meta-analyses concerning Ruxolitinib.
  • In the treatment of steroid-refractory graft-versus-host disease (SR-GvHD), Ruxolitinib showed promising effectiveness with an overall response rate ranging from 45% to100%, yielding significant results compared to other second-line therapies such as mesenchymal stroma cell addition or inolimomab.
  • For myelofibrosis treatment, earlier initiation of Ruxolitinib post-diagnosis resulted in improved overall survival rates, fewer cytopenia events, durable spleen volume response (SVR), making it more effective than placebo or the best available therapy.
  • When comparing different Janus kinase inhibitors for myelofibrosis treatment, like fedratinib and momelotinib; efficacy-wise, they were comparable, but side effect profiles varied, which might guide the choice between them.
  • In treating polycythemia vera patients who are intolerant or have had an inadequate response to hydroxyurea, thrombosis reduction favored Ruxolitinib over the best available therapy, although differences did not reach statistically significant levels. It also improved quality-of-life outcomes compared to conventional treatments.
  • The safety profile involves considerations for treatment-related toxicities, including cytopenia, liver toxicity, and infections. Ruxolitinib has been associated with increased risks of specific infections, notably herpes zoster, in the context of Myeloproliferative neoplasm (MPN) patients. However, the safety profile is deemed manageable and comparable to other options.
  • Ruxolitinib's advantages over other treatments include improved response rates and clinical outcomes, particularly for SR-GvHD and myelofibrosis. It offers an essential therapeutic choice for patients who have limited options due to resistance or intolerance to other therapies but requires careful monitoring for specific side effects, including increased risks of infections and cytopenia.
