The purpose of this study is to collect beginning information on whether intravenous (IV) administration of KRN5500 is safe and effective for treatment of neuropathic pain in patients with cancer.
Neuropathic pain is a type of pain that results from nerve damage and is characterized by an abnormal hypersensitivity to harmless as well as harmful stimuli. This type of pain is extremely difficult to manage, fails to respond to standard analgesic medications or interventions, and often gets worse instead of better over time. Current approved therapeutic agents often have intolerable side effects and limited efficacy. Thus, there is an urgent need to develop safe and effective drugs to treat neuropathic pain.

Study DTCL100 will be conducted at multiple centers and will enroll patients that have advanced cancer AND neuropathic pain that has not responded well to previous treatment. Eighteen patients will be randomly assigned to receive up to 8 doses of active drug (KRN5500) or placebo. A maximum of 8 doses will be administered weekly over a 10 week period. Patients are encouraged to complete at least 4 treatment visits before a decision is made to complete the full 10 weeks of treatment and the 1 month followup period.

Estimate

Drug KRN5500

Drug Placebo

Normal Saline given as dose escalation for placebo

KRN5500 Experimental

KRN5500 escalating dose of .6, 1.2, 1.8, or 2.2 mg/m2 in IV infusion of normal saline

Normal Saline Placebo Comparator

Placebo consists of IV infusion of normal saline
