Detailed Description:

Despite cisplatin chemoradiation, 40-50% of women with locally advanced cervical cancer will die from their disease. The evaluation of new chemoradiation regimens have since included cisplatin to further build on its current success. In one year, Nelfinavir will be off patent and become a potential cost effective therapy. HIV Protease inhibitors are now being explored as potential therapies in oncology. The repositioning of HIV protease inhibitors, specifically nelfinavir in cancer therapeutics, is based on three facts. First, recent studies show that HIV protease inhibitors are established broad-spectrum anti-cancer agents that work through pleiotropic mechanisms such as by down-regulating activated mitogenic signaling pathways, and activating the immune response with Nelfinavir being the most potent [7]. Second, HIV protease inhibitors including nelfinavir can target specific viral antigens. Nelfinavir has been shown to target Human Papilloma Virus (HPV)-transformed cervical carcinoma cells via inhibition of E6-mediated proteosomal degradation of mutant p53 [8]. Thirdly, Nelfinavir has radiosensitizing properties through inhibiting the PI3K/Akt signaling pathway as demonstrated in vivo and in vitro in head and neck and pancreatic cancers models [9].

Nelfinavir is currently being evaluated as a radiosensitizer in head and neck and pancreatic cancers in phase I/II clinical trials. Brunner et al. (2008) recently completed the first phase I trial of nelfinavir added to chemoradiation for locally advanced pancreatic cancer [16]. Investigators treated 12 patients with advanced pancreatic carcinoma with Nelfinavir 1250 mg orally twice daily starting 3 days before radiation therapy and continued until the last day of radiation. They found no significant toxicity attributable to nelfinavir and observed a response rate of 50% versus 30% in historical controls. There were 5 of 12 patients with grade 3 hematologic toxicities (4 with leukopenia and 2 with thrombocytopenia). There were 3 of 12 patients with grade 3 GI toxicity (including abdominal pain, nausea, vomiting). There were no grade 4 drug related toxicities [16]. There were grade 1/ 2 toxicities including hematologic (thrombocytopenia, anemia, neutropenia), gastrointestinal toxicities (nausea, vomiting, diarrhea, abdominal pain), and elevated transaminases which were approximately 70%. Ten of 12 patients completed therapy. Complete responses were observed in 5 patients and partial responses were observed in 5 of 10 patients. Overall, the addition of Nelfinavir added minimal additional toxicity. Determination of a dose for biologic activity was not performed [14].

In summary, HIV protease inhibitors have a very broad spectrum of anti-tumor activity and can inhibit proliferation and/or cause death in the majority of cancer cell lines tested in a dose-dependent manner [7]. Nelfinavir has been found to be the most potent anti-tumor agent among the HIV protease inhibitors. As a result, several clinical trials are investigating Nelfinavir as a chemotherapeutic agent with and without concurrent radiation therapy in varied disease sites including rectal, head & neck, glioblastomas, pancreas, renal cell, non-small cell lung cancer, liposarcoma, and gliomas. The NCI is also investigating Nelfinavir as single agent chemotherapy in advanced and recurrent solid tumors [15].

As Nelfinavir has both cytotoxic and radiation sensitizing effects, it is an ideal agent to use in combination with cisplatin-based chemoradiation in locally advanced cervical cancers.

In this study, patients with clinical stages IIA, IIB, IIIA, IIIB, IVA cervical carcinoma limited to the pelvis will receive twice daily oral Nelfinavir (NFV) and weekly IV cisplatin in combination as radiosensitizers with daily whole pelvic external beam (Mon-Fri) followed by intracavitary radiation brachytherapy.

Arm Intervention/treatment
Experimental: Nelfinavir + Cisplatin + Pelvic Radiation Therapy
Nelfinavir in combination with Cisplatin and Pelvic Radiation Therapy
Drug: Nelfinavir
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
Other Name: NFV

Drug: Cisplatin
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.

Radiation: Pelvic External Beam Radiation Therapy
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.
Other Name: PEBRT

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

Procedure: Pharmacokinetic Sampling
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.

Procedure: Cervical Biopsy
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
