  • Clinical and pharmacokinetic (PK) findings in a phase I study of 7-t-butyldimethylsilyl-10-hydroxycamptothecin (AR-67) in patients with refractory solid tumors. (Abstract #2534)
  • Pharmacokinetics (PK) of the Highly Lipophilic and Blood Stable Camptothecin AR-67 (7-t-butyldimethylsilyl-10-hydroxycamptothecin) in Adult Patients with Solid Malignancies. (Abstract #2546)
  • Metabolism and Transport Pathways of the Blood Stable Camptothecin AR-67 (7-t-butyldimethylsilyl-10-hydroxycamptothecin). (Abstract #2553)


The above poster presentations describe findings from the Phase I trial of AR-67 in cancer patients with a broad range of solid tumor types whose tumors had progressed on prior treatment regimens.


About AR-67


AR-67 is a novel, third-generation camptothecin analogue that has demonstrated high potency in preclinical studies and improved pharmacokinetic properties, compared with approved second-generation products, as demonstrated by the increased stability of the active lactone form of AR-67 in blood. Moreover, the potential for oral administration may increase patient convenience.


Arno has completed a Phase I single agent, clinical study of AR-67 in patients with advanced solid tumors. The study has established the maximum tolerated dose, and is evaluating the safety as characterizing the plasma Pk profile of AR-67. A Phase II study is planned for initiation during 2009 in glioblastoma multiforme (GBM) a highly aggressive form of brain cancer and a Phase II study is planned for initiation during 2009 in myelodysplastic syndrome (MDS).
