|Gilead Sciences to Acquire YM BioSciences|
- Adds Selective JAK Inhibitor to Growing Oncology and Inflammation Pipeline -
YM’s lead drug candidate, CYT387, is an orally-administered, once-daily, selective inhibitor of the Janus kinase (JAK) family, specifically JAK1 and JAK2. The JAK enzymes have been implicated in a number of disorders including myeloproliferative diseases, inflammatory disorders and certain cancers. YM has reported positive results from a Phase 1/2 clinical trial of CYT387 in 166 patients with myelofibrosis, a life-threatening myeloproliferative disease. Pending completion of the acquisition, Gilead intends to initiate a pivotal Phase 3 clinical trial of CYT387 in myelofibrosis in the second half of 2013.
“This acquisition represents an opportunity to add a complementary
clinical program in the area of hematologic cancers to our growing
oncology portfolio,” said
Myelofibrosis is a progressive, chronic bone marrow disorder in which the marrow is replaced by fibrous scar tissue, making it difficult for the bone marrow to sufficiently produce blood cells, leading to anemia (low red blood cell count) and thrombocytopenia (low blood platelet count), severe constitutional symptoms and spleen enlargement. JAK inhibitors modulate cytokine-stimulated intracellular signalling and decrease the circulating levels of proinflammatory cytokines associated with the pathogenesis of myelofibrosis.
“This agreement represents a positive outcome both for myelofibrosis patients and for our shareholders. Gilead has the research and development capabilities and the resources needed to more fully realize the potential of CYT387 as a therapeutic advance for myelofibrosis patients and potentially for other indications,” said Dr. Nick Glover, President and CEO of YM.
“Since our acquisition of CYT387 nearly three years ago, YM has made
great progress in advancing CYT387 through the clinical, regulatory,
manufacturing and business development processes. While Gilead's
acquisition will end a long, varied and interesting journey for YM, we
are pleased to have this transaction crystallize the present value of
this important therapeutic candidate,” said Mr.
In recent years, Gilead has sought to expand its R&D expertise in the area of oncology through the appointment of leading cancer researchers and clinicians, the establishment of external scientific partnerships and through strategic acquisitions. Gilead’s lead compound in oncology, idelalisib (formerly referred to as GS-1101), is an investigational, first-in-class specific inhibitor of the phosphoinositide-3 kinase (PI3K) delta isoform. Five Phase 3 studies of idelalisib in chronic lymphocytic leukemia (CLL) and indolent non-Hodgkin’s lymphoma (iNHL) are progressing.
Gilead is also conducting Phase 2 clinical trials of simtuzumab (formerly referred to as GS-6624), an investigational monoclonal antibody (mAb) candidate targeting the human lysyl oxidase-like 2 (LOXL2) protein, in myelofibrosis, colorectal cancer, pancreatic cancer and certain fibrotic diseases.
CYT387, idelalisib and simtuzumab are investigational products and their safety and efficacy have not yet been established.

YM BioSciences Inc. is a drug development company primarily focused on
advancing CYT387, an orally administered inhibitor of both the JAK1 and
JAK2 kinases, which have been implicated in a number of hematological
and immune cell disorders including myeloproliferative neoplasms and
inflammatory diseases as well as certain cancers. Positive interim
results have been reported from a Phase 1/2 trial of CYT387 in 166
patients with myelofibrosis. In addition, YM has several preclinical
programs underway with candidates from its library of novel compounds
identified through internal research conducted at
