Combination Pembrolizumab, Chemotherapy and Bevacizumab in Patients With Cervical Cancer

This is a single arm, open-label, phase II study to assess progression free survival in
patients treated with pembrolizumab, chemotherapy, and bevacizumab for recurrent, persistent,
or metastatic cervical cancer. Progression free survival will be assessed in patients treated
with this combination.

Eligible patients will require tissue biopsy for diagnostic confirmation of metastatic
disease, disease recurrence or persistence. Patients will be treated with 3 cycles of
combination therapy. A cycle will consist of pembrolizumab at 200mg (IV), paclitaxel 175mg/m2
or 135mg/m2 (IV), cisplatin 50mg/m2 (or carboplatin AUC 5) and bevacizumab 15mg/kg , on day 1
every 21 days. The length of a cycle is 21 days. If disease remains following 3 cycles, a
second biopsy may be obtained. Imaging will be obtained after every 3 cycles to assess for
disease response. Blood collection will be performed before and after pembrolizumab treatment
and at end of study.

Thirty-nine subjects will be accrued and treated at Sylvester Comprehensive Cancer Center
(SCCC)/University of Miami Hospital (UMH) inclusive of its satellite sites, and Jackson
Memorial Hospital for approximately 24 months. Therapy will be administered until study
completion, withdrawal of consent, disease progression and/or unacceptable toxicity,
whichever occurs first.

All subjects will be followed for a Safety Evaluation at approximately 30-days (+7 days)
after the last dose of study treatment or before the initiation of a new anti-cancer
treatment, whichever occurs first. Thereafter subjects will be followed every 3-months for up
to 24 months from the treatment discontinuation for survival data only.

10. Negative urine or serum pregnancy ≤72 hours (i.e. 3 days) prior to receiving the first
dose of study medication if not surgically sterilized. If the urine test is positive
or cannot be confirmed as negative, a serum pregnancy test will be required.

nonmelanoma skin cancer, are ineligible if there is any evidence of other malignancy
being present within the last 5 years.

2. Patients who have had prior chemotherapy except when used concurrently with radiation
therapy.

3. Patients who have received prior radiotherapy to any portion of the abdominal cavity
or pelvis other than for the treatment of cervical cancer within the last 5 years are
excluded. Prior radiation for localized cancer of the breast, head and neck, or skin
