Safety Study of Nelfinavir + Cisplatin + Pelvic Radiation Therapy to Treat Cervical Cancer

Nelfinavir (NFV) will be prescribed orally twice daily for 7 days prior to initiation of cisplatin and pelvic radiation at the starting dose level, 875 mg BID

Cisplatin at 40 mg/m2 (maximum total dose of 70 mg per week), will be infused intravenously once per week on either Day 1, 2, 3, 4, or 5 of weeks 2 to 6, preferably approximately four hours prior to radiation therapy. One additional cycle of cisplatin will be given either week 7 or 8 for a total of 6 cycles of cisplatin. Patients are not to be dosed more than 70 mg/week.

Pelvic external beam radiation therapy (PEBRT) will be delivered in combination with weekly IV cisplatin (40mg/mg2) and twice daily oral NFV.PEBRT should be delivered once each day during the business week (Monday to Friday) according to the acceptable standards of care as prescribed by the treating radiation oncologist(s). The radiation therapy should consist of whole pelvic external beam radiation therapy (WPEBRT) with or without a parametrial boost (PB). PEBRT will be interdigitated with one administration of intrauterine brachytherapy (BT) given on any business day of week 7 or 8.

PEBRT will be interdigitated with one administration of intrauterine brachytherapy (BT) given on any business day of week 7 or 8.

Serum levels of Nelfinavir will be assayed at the following 3 time points: 5-8 days after initiation of NFV single agent (on Day 5, 6, or 7 of week 1 or day 1 of week 2), 1 week after combined NFV and cisplatin pelvic radiation (on day 15, 16, or 17 if start on Monday) for measurement of steady state, and at the completion of treatment (within the last 3 days of radiation in week 6). Blood samples will be taken before drug administration on the day of the sample to make sure the concentrations are actually at a minimum and before tumor biopsies.

Three punch biopsies of cervical tumor will be obtained during office visit at each time point (for PCR, IHC, and banked for future research). NFV serum levels will be obtained once NFV has been started (day 5-8 pre chemoradiation and at completion of chemoradiation) before each cervical biopsy
