Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Patients with moderate to severe dysplasia and/or squamous carcinoma-in-situ of the oral cavity and/or oropharynx. - Patients with T1 squamous cell carcinoma of the oral cavity and/or oropharynx. - Patient may have primary and/or recurrent lesions to be treated. - Diagnosis must confirmed by biopsy. - Prior therapy of any type is allowed. - Male or female patients at least 18 years old. Female patients must not be pregnant and must be practicing a medically acceptable form of birth control, be sterile or post-menopausal. Male patients should be using a medically acceptable form of birth control or be sterile. - Patients must have an ECOG score of 0-2 (Appendix A 1 ). - Patient or legal representative must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure. Exclusion Criteria: - Patients with T2 or greater squamous cell carcinoma. - True tongue base lesions (as determined by the treating physician). - Patients with severe trismus that prevents adequate access to the lesion for treatment light delivery (as determined by the treating physician). - Porphyria or hypersensitivity to porphyrin or porphyrin-like compounds. - Patients with impaired hepatic (alkaline phosphatase (hepatic) or SGOT;:3 times the upper normal limits). - Patients with minimal impairment of renal function (total serum bilirubin;: 2 mg/dl, serum creatinine;: 2 mg/dl) - Unwilling or unable to follow protocol requirements. - Any condition which in the Investigator's opinion deems the patient an unsuitable candidate to receive study drug and or light treatment. - Patients on concurrent chemotherapy or radiation therapy or less than 4 weeks after the last dose of chemotherapy or radiation therapy. Inclusion of Women and Minorities: - Both men and women and members of all races and ethnic groups are eligible for this study.

Official title A Phase la Trial of Photodynamic Therapy With HPPH (2-1 (Hexyloxyethyl)-2-devinylpyropheophorbide-a) for Treatment of Dysplasia, Carcinoma in Situ and T1 Carcinoma of the Oral Cavity and/or Oropharynx.
Principal investigator Hassan Arshad, MD
Description We propose to initiate a Phase 1 a clinical trial using HPPH and 665 nm light in patients with cancer of the oral cavity and/or oropharynx, including lesions of moderate to severe dysplasia, squamous carcinoma in situ and T1 squamous cells carcinoma. The study will employ a fixed HPPH dose of 4 mg/m2 infused over 1 hour, and 24 hours later light doses escalating from 100 J/cm2 to 125 and 140 J/cm2, respectively. The primary goal is the determination of the maximally tolerated PDT dose. Preliminary evidence for PDT efficacy wil also be obtained.
