Photodynamic Therapy Using HPPH in Treating Patients With Dysplasia, Cancer in Situ, or Invasive Cancer of the Larynx
RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment for laryngeal cancer.
PURPOSE: This phase I trial is studying the side effects and best dose of laser light therapy when given together with HPPH in treating patients with dysplasia, cancer in situ, or invasive cancer of the larynx.
|Study Design:||Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I Trial of Photodynamic Therapy With HPPH (2-1[Hexyloxyethyl]-2-devinylpyropheophorbide-a) for Treatment of Dysplasia, Carcinoma in Situ and T1 Carcinoma of the Larynx|
- Toxicity [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
- Tumor response [ Time Frame: 3 months ] [ Designated as safety issue: No ]
|Study Start Date:||January 2008|
|Estimated Primary Completion Date:||November 2015 (Final data collection date for primary outcome measure)|
Experimental: Treatment PDT
Patients undergo PDT comprising HPPH IV over 1 hour on day 1 followed by laser light to the tumor on day 2. At least 6 weeks later, patients achieving partial response, no response, or a geographical miss may undergo a second course of treatment.
Given IVProcedure: laser therapy
Escalating light doses with 665 nm light
- To determine the maximum tolerated dose of laser light therapy using a fixed dose of HPPH in patients with dysplasia, squamous cell carcinoma in situ, or T1 squamous cell carcinoma of the larynx.
- To determine response in patients treated with this regimen.
OUTLINE: This is a dose-escalation study of laser light therapy.
Patients undergo photodynamic therapy comprising HPPH IV over 1 hour on day 1 and laser light therapy to the tumor on day 2. Approximately 8 weeks later, patients with a partial response, no response, or a geographical miss may receive a second course of treatment.
After completion of study treatment, patients are followed at 1 week, 1 month, 3 months, and then periodically thereafter.
