Study Description
Brief Summary:

RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that is absorbed by tumor cells. The drug becomes active when it is exposed to light. When the drug is active, tumor cells are killed.

PURPOSE: This phase I trial is studying the side effects and best dose of photodynamic therapy using HPPH in treating patients with recurrent dysplasia, carcinoma in situ, or stage I oral cavity cancer.

Condition or disease Intervention/treatment Phase
Head and Neck Cancer Drug: HPPH Phase 1

Detailed Description:



  • To determine the maximum tolerated dose in the oral cavity of photodynamic therapy (PDT) using HPPH and 665 nm light in patients with recurrent dysplasia, carcinoma in situ, or stage I squamous cell carcinoma of the oral cavity.


  • To determine response of dysplasia, carcinoma in situ, and selected patients with T1 squamous cell carcinoma of the oral cavity using PDT with HPPH and 665 nm light.

OUTLINE: This is a dose-escalation study of laser light dose therapy.

Patients receive HPPH IV over 1 hour on day 1. Approximately 24 hours after receiving HPPH, patients undergo laser light treatment to the tumor bed on day 2. Patients with multicentric or large area confluent disease receive a second course of treatment at least 8 weeks later for lesions untreated at the first treatment session.

After completion of study treatment, patients are followed at 1 week, 1 month, 3 months, and periodically thereafter.

Arms and Interventions

Arm Intervention/treatment
Experimental: Treatment (PDT)
Patients undergo PDT comprising HPPH IV over 1 hour on day 1 followed by laser light treatment to the tumor bed on day 2. Treatment may repeat every 8 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity.
Drug: HPPH

Outcome Measures

Primary Outcome Measures :
  1. Evidence of dose limiting Toxicities (DLT) [ Time Frame: First four weeks ]
    Each cohort of 3 patients will be observed for the first 4 weeks to monitor for DLT.

  2. Tumor response [ Time Frame: 3 months ]
