CytRx announces data from Phase 1b trial of aldoxorubicin

CytRx Corporation announced initial data from a Phase 1b clinical trial evaluating the pharmacokinetics and safety of aldoxorubicin, its novel conjugate of the widely used chemotherapeutic agent doxorubicin, in patients with metastatic solid tumors who have either relapsed or not responded to treatment with standard therapies. The data indicate that aldoxorubicin has a distribution half-life of 20-24 hours following infusion, which is significantly longer than doxorubicin’s initial half-life of five minutes. The data also demonstrate that aldoxorubicin demonstrated a distribution to healthy tissues that was 250-fold lower than that of doxorubicin. The company said, "We may consider further investigating aldoxorubicin in this indication among several others in the future. In fact, aldoxorubicin could be active against a variety of cancers, having shown to be superior to widely used doxorubicin in multiple animal models of cancer.”
