Primary Outcome Measures:
  • Calculate whole body and organ radiation dosimetry of I-131-CLR1404 to determine the millicurie dose which is expected to deliver 35-40 centigray of radiation to bone marrow [ Time Frame: 42 days ]

Secondary Outcome Measures:
  • To determine the safety and pharmacokinetic profile of I-131-CLR1404 [ Time Frame: 42 days ]

Estimated Enrollment: 9
Study Start Date: June 2009
Study Completion Date: February 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dosimetric Drug: I-131-CLR1404
Single intravenous injection of 10 millicuries of I-131-CLR1404 given on Day 0
Other Names:
  • CLR1404
  • 1404

Detailed Description:
I-131-CLR1404 is a small-molecule, phospholipid ether analog that combines lipid-like properties with a cancer therapeutic beta-emitting radioisotope. Cellectar believes that this compound will benefit individuals with cancer due to its selective retention and accumulation in malignant cells versus nonmalignant cells. Preclinical experiments have demonstrated that I-131-CLR1404 significantly slows malignant tumor growth in several mouse tumor models.
