Study Details

Study Description

Brief Summary

Phase I trial to study the effectiveness of photodynamic therapy with lutetium texaphyrin in treating patients who have cervical intraepithelial neoplasia. Photodynamic therapy uses light and drugs such as lutetium texaphyrin that make abnormal cells more sensitive to light and may kill abnormal cells in the cervix and prevent the development of cervical cancer

Condition or Disease Intervention/Treatment Phase
  • Drug: motexafin lutetium
  • Drug: photodynamic therapy
  • Procedure: loop electrosurgical excision procedure
  • Other: laboratory biomarker analysis
Phase 1

Detailed Description

OBJECTIVES:
  1. Determine the optimal dosage with the least toxicity of lutetium texaphyrin as well as the length of time following its systemic injection that provides the maximum differential in drug uptake between the target dysplastic squamous cells and normal squamous epithelium when given to patients with cervical intraepithelial neoplasia (CIN).

  2. Determine, by histomorphometry, the photodynamic light dose that demonstrates the greatest treatment selectivity between normal cervical epithelium and CIN with the least amount of cervical pain and necrosis.

OUTLINE: This is a dose-escalation study of lutetium texaphyrin (part 1) followed by a dose-escalation study of light fluence (part 2).

Part 1: Patients receive lutetium texaphyrin IV over 5-20 minutes. Patients undergo in vivo tissue assessment by spectrometer at 0, 1, 3, 5, 12, and 24 hours and loop electrical excision procedure (LEEP) at 24 hours after lutetium texaphyrin infusion.

Part 2: Patients receive lutetium texaphyrin IV over 5-20 minutes. A laser delivers 730 nm of light to the cervix for 4, 8, or 16 minutes. Patients undergo LEEP at 4, 8, or 12 hours after exposure of the cervix to the light source.

Cohorts of 9 patients receive escalating doses of lutetium texaphyrin (part 1) and then light fluence (part 2) until the maximum tolerated dose (MTD) of each is determined. The MTD is defined as the dose preceding that at which 2 of 9 patients experience dose-limiting toxicity.

Patients are followed at 48 hours, weekly for 1 month, and then at 4 months.

PROJECTED ACCRUAL: A maximum of 54 patients will be accrued for this study.

    Outcome Measures

    Primary Outcome Measures

    1. Optimal dosage with the least toxicity of lutetium texaphyrin (Part 1) [Up to 24 hours]

      A simplified graphical analysis will be utilized to determine the drug dose and time after administration that provides the largest differential area between lutein texaphyrin tissue levels in neoplastic and normal cervical tissue

    2. Maximal differential in Lutrin tissue levels between normal and dysplastic cells (Part 1) [At the time of LEEP]

    3. Percentage of tissue demonstrating PDT related effects (apoptosis/ necrosis) for normal versus abnormal epithelium at each total fluence for each LEEP cone biopsy specimen [At LEEP time]

      A simplified graphical analysis will be utilized to determine the fluence that provides the maximal differential area between neoplastic and normal cervical epithelium and stroma.
