In patients with advanced hepatocellular carcinoma, median survival and the time to radiologic progression were nearly 3 months longer for patients treated with sorafenib than for those given placebo. (ClinicalTrials.gov number, NCT00105443.)

These exploratory subgroup analyses showed that sorafenib consistently improved median OS and DCR compared with placebo in patients with advanced HCC, irrespective of disease etiology, baseline tumor burden, performance status, tumor stage, and prior therapy.

Oral BAY 43-9006 was well tolerated and appeared to provide some clinical benefits. Based on the results of this study, BAY 43-9006 at 400 mg bid continuous is recommended for ongoing and future studies.

BACKGROUNDIn this study, the authors analyzed the efficacy and safety of gemtuzumab ozogamicin (GO) (Mylotarg®), an antibody‐targeted chemotherapy for CD33‐positive acute myeloid leukemia (AML).METHODSPatients with CD33‐positive AML in first recurrence were entered in 3 open‐label, single‐arm, Phase II studies. Patients received monotherapy with GO 9 mg/m2 as a 2‐hour intravenous infusion in 2 doses separated by 2 weeks. Patients were evaluated for remission, survival, and treatment‐emergent adverse events.RESULTSTwo hundred seventy‐seven patients (median age, 61 yrs) were treated with GO, and 71 patients (26%) achieved remission, which was defined as ≤ 5% blasts in the bone marrow without leukemic blasts in the peripheral blood, neutrophil recovery to ≥ 1500/μL, hemoglobin ≥ 9 g/dL, and independence from red blood cell and platelet transfusions. Complete remission (CR) with platelet recovery (≥ 100,000/μL) or without full platelet recovery (< 100,000/μL) (CRp) was observed in 35 patients (13%) and 36 patients (13%), respectively. The median recurrence‐free survival was 6.4 months for patients who achieved CR and 4.5 months for patients who achieved CRp. Although expected incidences of Grade 3 or 4 neutropenia (98%) and thrombocytopenia (99%) were observed, the incidence of Grade 3 or 4 sepsis (17%) and pneumonia (8%) was relatively low. Grade 3 or 4 hyperbilirubinemia and hepatic aspartate aminotransferase and alanine aminotransferase elevations were reported in 29%, 18%, and 9% of patients, respectively; 0.9% of patients who did not undergo prior or subsequent hematopoietic stem cell transplantation developed hepatic venoocclusive disease after GO treatment.CONCLUSIONSWhen it was administered to patients with CD33‐positive AML in first recurrence, single‐agent GO induced a 26% remission rate with a generally acceptable safety profile.
