Sunesis Announces Initiation of Phase 1 Study of MLN2480 in Advanced Solid Tumors
SOUTH SAN FRANCISCO, Calif., Sep 26, 2011 (GlobeNewswire via COMTEX) -- Sunesis Pharmaceuticals, Inc. (Nasdaq:SNSS) today announced the initiation of a Phase 1 clinical study of MLN2480, an oral, investigative drug selective for pan-Raf kinase inhibition, that is being studied in patients with relapsed or refractory solid tumors. The study is sponsored by Millennium Pharmaceuticals, Inc., which is developing MLN2480 in oncology in collaboration with Sunesis. Under their agreement, Sunesis is eligible to receive milestone payments and royalties on sales of future collaboration products and retains future co-development and co-promotion rights.
The Phase 1, multicenter, open-label, dose escalation study will evaluate the safety, tolerability and maximum tolerated dose (MTD) of single agent MLN2480, and will be conducted in two stages: dose escalation and dose expansion. The dose escalation phase will include patients with advanced solid tumors who have failed or are not candidates for standard therapies or for whom no approved therapy is available. Secondary endpoints will assess preliminary antitumor activity, as well as pharmacokinetic and pharmacodynamic properties of MLN2480.
"The significant progress made with MLN2480 in just a few short months attests to its priority under Millennium's direction," said Daniel Swisher, Chief Executive Officer of Sunesis. "MLN2480 is a pan-Raf kinase inhibitor with a distinct molecular signature which has exhibited a promising preclinical profile. We are pleased to see that Millennium's project team has rapidly moved this program into Phase 1, and look forward to evaluating the program as it reaches the next phase of development."
About Raf Kinases
The Raf kinases (A-Raf, B-Raf and C-Raf) are key regulators of cell proliferation and survival within the mitogen-activated protein kinase (MAPK) pathway. The MAPK pathway is frequently disregulated in human cancers, often via activating mutations of Ras or Raf.
