People with myelofibrosis who are currently receiving ruxolitinib therapy may be eligible for a new phase II clinical trial led by Dr. Ellen Ritchie.
Navitoclax is an investigational agent that inhibits a family of BCL proteins. These proteins block some of the enzymes that keep cancer cells from dying and by inhibiting these proteins, navitoclax may cause the cancer cells to die. Ruxolitinib is approved by the FDA for the treatment of myelofibrosis. Ruxolitinib blocks a protein called Janus-associated kinases (JAK) which may help keep abnormal blood cells or cancer cells from growing.
The purpose of this study is to evaluate the addition of navitoclax to ruxolitinib in patients who have been receiving ruxolitinib alone. Ruxolitinib treatment alone has not been fully controlling disease which is evident by an enlarged spleen. Preclinical data suggest that the combination of navitoclax with ruxolitinib are synergistic and that navitoclax may help to overcome disease resistance to ruxolitinib.
The study will help to determine the effect of the combination of navitoclax plus ruxolitinib on your cancer. The study will evaluate how the efficacy and safety of the drug.
