Official title

A Phase I Study of Photodynamic Therapy (PDT) Plus Vitamin D3 for High-grade Anal Dysplasia and Microinvasive Anal Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a phase I dose escalation study of photodynamic therapy (PDT) for the treatment of patients with pre-malignant tumors and superficial microinvasive disease of the anal canal and/or perianal skin. All subjects (a maximum of 12) will be given the photosensitizer ALA orally followed by the administration of red light (629-635 nm) to the tumor from a laser. The dose of ALA will be 40 mg/kg administered approximately 4-6 hours before light administration. There will be two levels of light dose: 50 and 100 J/cm2, 3-6 patients in each. Vitamin D3 (cholecalciferol) supplementation (10,000 IU daily) will be provided from 3 days prior through 14 weeks after light delivery for PDT. Patients will be observed for 30 days for the development of DLT. Patients will be followed up for 24 months for additional toxicity and efficacy data collection.
