Brief Summary: Patients with refractory or relapsed acute myeloid leukemia AML after two courses of standard chemotherapy regimens have very limited options Further chemotherapy is associated with significant toxicity and is generally ineffective About 10-30 patients with AML carry a gain-of-function mutation of a gene known as Flt3 in the leukemic cells conferring them with abnormal cellular proliferation Sorafenib is a multi-kinase inhibitor which was licensed in Hong Kong for the treatment of advanced hepatocellular and renal cell carcinoma The drug has also been shown to be effective against Flt3 and AML but it has not been licensed for use in this condition
Detailed Description: AML is one of the most lethal cancers among young people in Hong Kong Induction chemotherapy is the mainstay of treatment resulting in remission ie clearance of leukemic cells in 70 cases Patients who fail induction chemotherapy or who relapse after initial remission would need to receive further chemotherapy with a view to achieve a second remission Those who do so can be potentially cured by bone marrow transplantation BMT Those who fail are left with very little options As a result only 30 patients can survive long-term

AML is heterogeneous and 10-30 patients carry a gain-of-function mutation of a gene known as fms-related tyrosine kinase-3 Flt3 in the leukemic cells which confers them with abnormal cellular proliferation These patients have inferior prognosis compared with those without the mutation With conventional chemotherapy these leukemias often fail to remit precluding patients from receiving curative BMT Sorafenib is a multi-kinase inhibitor which is FDA approved for the treatment of metastatic hepatocellular and renal cell carcinomas It is also effective against Flt3 and has been shown to be very effective in inducing remission in patients with AML carrying Flt3 mutation

This proposal aims to treat relapsed or refractory AML patients carrying Flt3 mutation in the following ways

1 Patients who have persistent or refractory leukemia after at least two prior chemotherapy regimens will receive sorafenib to induce a remission hence bridging them to BMT for curative treatment
2 Patients who relapse after BMT will receive sorafenib to induce remission again in preparation for second BMT
3 Patients who are not candidates for BMT but have persistent or refractory leukemia after at least two prior chemotherapy regimens will receive sorafenib to induce a remission followed by chemotherapy consolidation Sorafenib induction will have significantly less side-effects compared with induction by conventional chemotherapy

Patients who are treated with sorafenib will be managed in the hospital and out-patient clinics in the same way as patients undergoing induction by conventional chemotherapy They will have bone marrow examinations before and one month after receiving sorafenib treatment
