Cancer: The effect of HIV-1 protease inhibitor nelfinavir combined with standard radiotherapy and chemotherapy in the treatment of locally advanced cervical cancer

Nelfinavir (Nelfinavir, NFV) is an HIV-1 protease inhibitor that has been shown to increase the sensitivity of cancer cells to chemical radiation (CRT) .

This study is a phase 1 clinical trial to evaluate the safety of NFV for locally advanced cervical cancer and determine the recommended phase 2 clinical trial dose of NFV combined with simultaneous CRT for the treatment of locally advanced cervical cancer.

Two dose levels of NFV were evaluated: 875 mg, oral, 2/day (dose level 1 [DL1]) and 1250 mg, oral, 2/day (DL2).

Research results show that NFV ground can indeed increase the sensitivity of cervical cancer cells to radiotherapy, increase cell apoptosis, and enhance tumor suppression in vivo .

In the DL1 group, after one patient had dose-limiting toxicity, 6 patients required dose expansion, while patients in the DL2 group had no dose-limiting toxicity.

DL2 is determined as the recommended phase 2 dose

All patients in the DL2 group completed CRT, and 1 out of 6 patients developed grade 3/4 anemia, nausea, and diarrhea.

During a median follow-up of 50 months, 10 of 11 evaluable patients still showed no signs of disease recurrence .

In addition, NFV can significantly reduce the level of phosphorylated Akt in tumors.

In short, CRT combined with NFV is well tolerated .
