Dr. Rampal on the Role of JAK Inhibitors in Myelofibrosis

Raajit K. Rampal, MD, PhD, hematologic oncologist, associate attending physician, Memorial Sloan Kettering Cancer Center, discusses a presentation given at the Baptist Health South Florida Miami Cancer Institute Global Summit on Immunotherapies for Hematologic Malignancies on how the role of JAK inhibitors will continue to evolve in the treatment of patients with myelofibrosis.

patients with myelofibrosis, Rampal begins. However, it is not believed that JAK inhibitors modify the disease, and their effects can be limited in subgroups of patients, Rampal says.

Multiple JAK inhibitors are now available for the treatment of myelofibrosis, and this has allowed select patients to potentially be cycled between different agents, Rampal explains. As more data have emerged, they have been able to demonstrate how various JAK inhibitors can effect patients differently, and this may put clinicians in a position to better select certain JAK inhibitors for select patients, Rampal emphasizes.

Within the next 2 to 3 years, it is possible that the treatment landscape for patients with myelofibrosis will drastically shift, Rampal says. Multiple agents are in late phase 3 trials, and if data continue to prove positive for some or all of these treatments, there will be an influx of new treatment options entering clinical practice, Rampal notes.

Although the landscape will change, it remains unclear exactly how that will happen. One possible scenario is that trials for the drugs in development are successful, and then clinicians will need to determine if these treatments will be added on to current regimens for use in combinations, or if they should follow the use of JAK inhibitors if a patient does not have a full response, Rampal notes. These remain unanswered questions, but they will be addressed in short time as other agents begin to enter the treatment landscape, Rampal concludes.
