PALO ALTO, Calif., Dec. 9 /PRNewswire-FirstCall/ -- Telik, Inc. reported today positive preclinical data demonstrating that TELINTRA (TLK199) accelerated the recovery of white blood cells (neutrophils) in standard preclinical models of chemotherapy-induced neutropenia. The company reported that neutrophil recovery was also mediated and preceded by significantly increased levels of G-CSF and GM-CSF. Recombinant G-CSF and GM- CSF are the current standards of care for the treatment of cancer patients with chemotherapy-induced neutropenia. The data were presented at the 46th annual meeting of the American Society of Hematology.
Results demonstrated that a single oral or injected dose of TELINTRA resulted in up to a 500% increase in serum G-CSF levels. In a standard model of neutropenia, TELINTRA accelerated the recovery of circulating neutrophils, and this recovery corresponded to earlier peak serum G-CSF levels. In a separate study, treatment of primary human bone marrow stromal cells with TELINTRA resulted in production of G-CSF, GM-CSF and interleukin-6 at levels 200% to 400% greater than control.
"The opportunity to evaluate an oral formulation of TELINTRA in a Phase 1- 2a trial following a successful Phase 1-2a trial of the parenteral formulation in myelodysplastic syndrome adds significant breadth to the development program," said Michael K. Inouye, senior vice president, commercial operations. "These new data support further development of TELINTRA for potential use in cytopenia associated with cancer chemotherapy."
