SAN FRANCISCO, Nov. 15, 2011 /PRNewswire/ -- Nektar Therapeutics (NASDAQ: NKTR) today presented positive preclinical data for NKTR-102, a next-generation topoisomerase I inhibitor, at the 2011 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer being held in San Francisco, California. The preclinical data demonstrates that NKTR-102 administered in combination with pegylated liposomal doxorubicin (PLD) in vivo has strong synergistic anti-cancer properties exhibiting a 100% complete response rate with no tumor re-growth in over 90% of animals. In addition, the study showed that there was no additive toxicity when combining NKTR-102 with PLD in a preclinical model of ovarian cancer.
"Results from these nonclinical studies of NKTR-102 combined with PLD and as a single agent are highly compelling," said Robert Medve, M.D., Chief Medical Officer of Nektar Therapeutics. "In the models of platinum-resistant ovarian cancer, NKTR-102 showed synergistic anti-tumor activity with PLD. These preclinical data support the future exploration of NKTR-102 in combination with PLD in platinum-resistant ovarian cancer."
The data presented at the 2011 AACR-NCI-EORTC meeting show that in an in vivo model of platinum-resistant human ovarian cancer, a single-dose of single-agent NKTR-102 resulted in a 100 percent complete response rate and a delay in tumor growth of up to 38 days at the highest dose. In the same model, multiple doses of single-agent PLD achieved only one partial response and a delay in tumor growth of up to only 24 days at its highest dose. NKTR-102 administered in combination with PLD showed synergistic anti-tumor activity with a 100 percent complete response rate and no tumor re-growth for 93% of the animals within a 69-day observation period.
