About Sierra Oncology
Sierra Oncology is a late stage
drug development company focused on advancing targeted therapeutics
for the treatment of patients with significant unmet medical needs
in hematology and oncology.
Momelotinib, Sierra's lead drug
candidate, is a potent, selective and orally-bioavailable JAK1,
JAK2 & ACVR1 inhibitor with a differentiated therapeutic
profile in myelofibrosis encompassing robust constitutional symptom
improvements, a range of meaningful anemia benefits, including
eliminating or reducing the need for frequent blood transfusions,
and comparable spleen control to ruxolitinib. More than 1,200
subjects have received momelotinib since clinical studies began in
2009, including more than 800 patients treated for myelofibrosis.
Sierra recently launched the MOMENTUM
Phase 3 clinical trial, a randomized double-blind trial designed to
enroll 180 myelofibrosis patients who are symptomatic and anemic,
and who have been treated previously with a JAK inhibitor.
The U.S. Food and Drug Administration has granted Fast Track
designation to momelotinib for the treatment of patients with
intermediate/high-risk myelofibrosis who have previously received a
JAK inhibitor. Momelotinib is wholly owned by Sierra Oncology and
is protected by patents anticipated to provide potential
exclusivity to 2040 in the United
States and Europe
(including Patent Term Extension or Supplementary Protection
Certificate).
Sierra is also developing a
portfolio of DNA Damage Response (DDR) assets, consisting of SRA737
and SRA141, and is conducting a campaign intended to seek
non-dilutive strategic options to support their further
advancement. SRA737 is a potent, highly selective, orally
bioavailable small molecule inhibitor of Checkpoint kinase 1
(Chk1), a key regulator of cell cycle progression and the DDR
network, and has demonstrated preliminary clinical efficacy. SRA141
is a potent, selective, orally bioavailable small molecule
inhibitor of Cell division cycle 7 kinase (Cdc7) with a potential
novel mechanism of cytotoxicity, and has successfully completed the
IND process with the FDA enabling the commencement of clinical
trials. Sierra retains the global
commercialization rights to SRA737 and SRA141.
