Population: Only participants in Stratum 2 contributed data for this Outcome Measure

Clinical response was defined as a protocol-specified improvement in ophthalmologic evaluation, an improvement of at least one level in performance status (PS) ≥50% decrease in the amount of pain medications required per week compared with baseline or ability to change from a narcotic to a nonnarcotic analgesic, sustained for at least one month.
