Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects were identified in the head and neck oncology clinic and enrolled into the study within the time period of January 1, 2007 to November 18, 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Screen failure did meet incl./excl. criteria

Reporting Groups
  Description
Phase I

To determine the maximum tolerated energy density of the Pulse Dye Laser operated at 585 nm with a pulse time of 1.5 ms (PDL-585), when used in combination with 5-aminolevulinic acid (5-ALA) applied topically to the premalignant lesion.

The maximum tolerated energy density will be called the Maximum Tolerated Dose (MTD).

Phase II During Phase II, to assess the treatment efficacy of PDL-585 when used at the MTD in combination with 5-ALA applied topically to the premalignant lesion. Treatment efficacy will be assessed by means of the 90-day Objective Response rate observed among study subjects treated at the MTD.

  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Maximum Tolerated Dose   [ Time Frame: Day 2 ]

2.  Primary:   The Objective Response Rate is the Number of Participants With Significant Response (SR), Partial Response (PR) or No Response (NR).   [ Time Frame: Day 90 ]

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Since all but one subject responded to treatment, no correlative analysis of response with change in expression of p53 or Ki-67 was undertaken.
