About this study

Low-dose MTX is a widely used, inexpensive, and safe therapy used for decades and is well tolerated by patients with rheumatologic diseases. Recently, it was identified as a type 2 JAK inhibitor. If MTX proves to be safe and tolerable with a signal of clinical activity, this could have a significant benefit to patients with MPNs. Beyond the potential benefit of adding a type 2 JAK inhibitor to current therapy, this could signal the need to study MTX in MPNs further as a monotherapy. Discovering MTX as safe and clinically effective in MPNs could be profound on both a public health and global health scale for patients who are uninsured and cannot afford more expensive novel JAK inhibitors, or for those in countries where JAK inhibitors are not available. Accordingly, the research team deems it reasonable and prudent to assess the safety and efficacy of MTX in addition to current therapy for patients with MPN. The research team will evaluate patients for spleen responses, symptom responses, and cytologic responses. Correlative data will evaluate pharmacokinetic and disease modifying activity of MTX in MPNs to inform future clinical trials.
