MOMENTUM: momelotinib vs danazol in patients with myelofibrosis previously treated with JAKi who are symptomatic and anemic.

Hallmark features of myelofibrosis (MF) are cytopenias, constitutional symptoms and splenomegaly. Anemia and transfusion dependency are among the most important negative prognostic factors and are exacerbated by many JAK inhibitors (JAKi). Momelotinib (MMB) has been investigated in over 820 patients with MF and possesses a pharmacological and clinical profile differentiated from other JAKi by inhibition of JAK1, JAK2 and ACVR1. MMB is designed to address the complex drivers of iron-restricted anemia and chronic inflammation in MF and should improve constitutional symptoms and splenomegaly while maintaining or improving hemoglobin in JAKi-naive and previously JAKi-treated patients. The MOMENTUM Phase III study is designed to confirm and extend observations of safety and clinical activity of MMB.

Lay abstract The most important features of myelofibrosis (MF) are low blood cell counts and symptoms including tiredness, night sweats and itching, along with increased size of the spleen, which may cause a feeling of fullness and pain. Low red blood cell counts (anemia) may mean regular blood transfusions are needed and this is one of the signs MF is getting worse. Drugs called JAK inhibitors (JAKi) are available to treat MF, but can have a side effect of making blood cell counts lower. Momelotinib (MMB) is a different type of JAKi to the ones currently available, and is an experimental drug for MF. MMB is designed to treat symptoms and spleen like other JAKi, but also to improve blood cell counts. MMB has already been given to more than 820 patients with MF in other clinical studies. Some of the patients in these studies had been treated with different JAKi before, and others got MMB as their first JAKi treatment. The MOMENTUM Phase III study is designed to collect more information on the safety and effectiveness of MMB in MF.

The impact of frontline risk-adapted strategy on the overall survival of patients with newly diagnosed multiple myeloma: an analysis of the Singapore multiple myeloma study group.

INTRODUCTION: Risk stratification is vital for prognostication and informing treatment decisions in multiple myeloma (MM). We study the prognostic values of the International Staging System (ISS) and underlying cytogenetics in the bortezomib era and assess the impacts of an upfront risk-adapted approach in the treatment of MM. METHODS: We compare the overall survival (OS) of 221 patients with MM diagnosed from 2006 to 2009 (era 2) where upfront bortezomib combination was approved for high-risk MM with the OS of 262 patients diagnosed from 2000 to 2005 (era 1) where bortezomib could only be administered at relapse. High-risk MM is defined by the presence of ISS III disease with renal impairment or adverse cytogenetics. RESULTS: Baseline characteristics were comparable between the 2 eras. At median follow-up of 20 months, 0% and 26% of patients had received frontline bortezomib in eras 1 and 2, respectively. The median OS were 4.2 yrs and not reached for eras 1 and 2, respectively (P = 0.03). On multivariate analysis stratified by era, the most significant prognostic factor shifts from cytogenetics in era 1 to the quality of response in era 2. CONCLUSION: Frontline use of bortezomib in a risk-adapted manner may avert early mortality and is better able to overcome adverse risks compared to its sequential use.

Outpatient-based therapy of oral fludarabine and subcutaneous alemtuzumab for asian patients with relapsed/refractory chronic lymphocytic leukemia.

Background. Intravenous alemtuzumab and fludarabine are effective in combination for the treatment of chronic lymphocytic leukemia (CLL), but require hospital visits for intravenous injection. We performed a pilot study to assess the safety and efficacy of outpatient-based oral fludarabine with subcutaneous alemtuzumab (OFSA) for the treatment of relapsed/refractory CLL. Results. Depending on their response, patients were given two to six 28-day cycles of subcutaneous alemtuzumab 30 mg on days 1,3, and 5 and oral fludarabine 40 mg/m(2)/day for 5 days. Median patient age was 74. The lymphocyte counts of all five patients fell after the 1st cycle of treatment and reached normal/low levels on completion of 2 to 6 cycles of therapy. Platelet counts and hemoglobin were unaffected. All five patients achieved complete hematological remission, while two attained minimal residual disease negativity on 4-color flow cytometry. Conclusions. Our OFSA regimen was effective in elderly Asian patients with relapsed/refractory CLL, and it should be investigated further.
