The investigators have determined that the drug amantadine hydrochloride is metabolized by acetylation by a specific enzyme named spermidine/spermine N-acetyltransferase (SSAT). This enzyme is increased in cancer cells. The investigators hypothesized that the amount of N-acetylamantadine excreted in urine during the first 12 hours after an oral dose would serve as a diagnostic biomarker for the presence of cancer in a human test subject.

Condition Intervention Phase

Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label

Primary Outcome Measures:
  • Amount of N-acetylamantadine excreted in a 12 hour urine sample collected after a single oral dose of amantadine hydrochloride ingested two hours after supper [ Time Frame: 12 hours ]

Enrollment: 150
Study Start Date: December 2003
Study Completion Date: July 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Patients with a medical diagnosis of cancer appearing at outpatient clinics for treatment and/or monitoring of their disease status
Drug: Ingestion of a 200 mg dose of amantadine hydrochloride
Volunteer cancer patients ingest 2 x 100 mg tablets of amantadine hydrochloride with a glass of cold water 2 hours after supper.
Active Comparator: 2
Healthy adult volunteers
Drug: Ingestion of a 200 mg dose of amantadine hydrochloride
Healthy subject ingests 2 x 100 mg tablets of amantadine hydrochloride with a glass of cold water 2 hours after supper

Detailed Description:
When patients present to their physician with symptoms of cancer at a later stage of development, survival tends to be poorer. Earlier diagnosis of cancer is expected to provide improved survival of patients due to earlier treatment intervention. However, implementation of this screening process is impaired by access and by cost. A simple and inexpensive test would serve as a screening tool that could be safely repeated at regular intervals to identify persons for whom more expensive and less accessible diagnostic investigations might become more appropriately directed. The specificity for an enzyme that increases markedly in cancer tissue, and the ease of administration of an already licensed pharmaceutical prescription product, amantadine hydrochloride, would appear to provide promise of such a desirable screening test.
