Summary
Brief summary
MOMENTUM is a randomized, double-blind, active control Phase 3 trial intended to confirm the
differentiated clinical benefits of the investigational drug momelotinib (MMB) versus danazol
(DAN) in symptomatic and anemic participants who have previously received an approved Janus
kinase inhibitor (JAKi) therapy for myelofibrosis (MF). The purpose of this clinical study is
to compare the effectiveness and safety of MMB to DAN in treating and reducing: 1) disease
related symptoms, 2) the need for blood transfusions and 3) splenomegaly, in adults with
primary MF, post-polycythemia vera MF or post-essential thrombocythemia MF. The study is
planned in countries including, but not limited to: Australia, Austria, Belgium, Bulgaria,
Canada, Czech Republic, Denmark, France, Germany, Hungary, Israel, Italy, New Zealand,
Poland, Romania, Singapore, South Korea, Spain, Sweden, Taiwan, United Kingdom (UK) and
United States (US).

Participants must be symptomatic with a Myelofibrosis Symptom Assessment Form (MFSAF) version
(v) 4.0 Total Symptom Score of >= 10 at screening, and be anemic with hemoglobin (Hgb) < 10
gram/deciliter (g/dL). For participants with ongoing JAKi therapy at screening, JAKi therapy
must be tapered over a period of at least 1 week, followed by a 2-week non-treatment washout
interval prior to randomization.

Participants will be randomized 2:1 to orally self-administer blinded treatment: MMB plus
placebo or DAN plus placebo. Participants randomized to receive MMB who complete the
randomized treatment period to the end of Week 24 may continue to receive MMB in the
open-label extended treatment period to the end of Week 204 (a total period of treatment of
approximately 4 years) if the participants tolerates and continues to benefit from MMB.

Participants randomized to receive DAN may cross-over to MMB open-label treatment in the
following circumstances: at the end of Week 24 if they complete the randomized treatment
period; or at the end of Week 24 if they discontinue treatment with DAN but continue study
assessments and do not receive prohibited medications including alternative active anti-MF
therapy; or at any time during the randomized treatment period if they meet the
protocol-defined criteria for radiographically confirmed symptomatic splenic progression.
Participants randomized to receive DAN who are receiving clinical benefit at the end of Week
24 may choose to continue DAN therapy up to Week 48. The comparator treatment, DAN, is an
approved medication in the US and in some other countries and is recommended by national
guidelines as a treatment for anemia in MF.
