Lenvatinib, Pembrolizumab, and Paclitaxel for Treatment of Recurrent Endometrial, Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

Study Overview
=================
Brief Summary
-----------------
This phase II clinical trial studies the effect of lenvatinib, pembrolizumab, and paclitaxel in treating patients with endometrial, epithelial ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent). While all 3 study drugs are FDA approved, and 2-drug combinations have been studied, the 3- drug combination has not been studied yet. The investigators believe that the addition of pembrolizumab to weekly paclitaxel and lenvatinib (or weekly paclitaxel to pembrolizumab and lenvatinib) is highly effective and safe with manageable side effects in both recurrent endometrial and platinum resistant ovarian cancer. The purpose of this trial is to study how well lenvatinib, pembrolizumab, and weekly paclitaxel work together in women who have recurrent endometrial cancer and/or recurrent platinum resistant ovarian, fallopian tube, and primary peritoneal cancer, and what kind of side effects patients may experience.

Detailed Description
-----------------
PRIAMRY OBJECTIVE: I. To determine objective antitumor activity (complete and partial response) of lenvatinib, pembrolizumab, and weekly paclitaxel as measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria in recurrent endometrial and platinum resistant ovarian cancer. SECONDARY OBJECTIVES: I. To determine the safety and tolerability weekly paclitaxel, lenvatinib, and pembrolizumab in study patients. II. To measure the progression free survival in the study population. III. To measure the overall survival in the study population. EXPLORATORY OBJECTIVE: I. To explore the baseline tumor genetic and microenvironment parameters predictive of clinical benefit or resistance to the treatment combination and potential mechanisms of resistance. OUTLINE: Beginning cycle 1 day 1, patients receive lenvatinib PO daily, pembrolizumab IV on day 1, and paclitaxel IV over 1 hour on days 1, 8, and 15, on a 21 day cycle in the absence of disease progression or unacceptable toxicity.

Note: no testing for hepatitis B and hepatitis C is required unless the patient is at risk for, or has symptoms or signs of, hepatitis Has a known history of active TB (Bacillus Tuberculosis) Known human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with pembrolizumab, lenvatinib and paclitaxel. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated Significant cardiovascular disease Major surgical procedure (e.g. laparotomy, bowel resection) 4 weeks prior to start of the study drug. Neuropathy grade > 1 Non-healing wound, bone fracture, or skin ulcer Active peptic ulcer disease, inflammatory bowel disease, ulcerative colitis, or other gastrointestinal condition with increased risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 4 weeks prior to administration of first dose of study drug Patients who have a history of a small or large bowel obstruction within 2 weeks of screening or who have and active partial small bowel obstruction or percutaneous endoscopic gastrostomy (PEG)-tube Serious/active infection or infection requiring parenteral antibiotics Significant arterial or venous thromboembolic disease or vascular disorders within 6 months prior to administration of first dose of study drug, including by not limited to: Cerebrovascular accident (CVA) or transient ischemic attack (TIA) Peripheral ischemia > grade 2 (per Common Terminology Criteria for Adverse Events [CTCAE] version 4.03) Arterial thrombotic event Patients who have a history of deep vein thrombosis or pulmonary embolus < 3 months prior to enrollment must be excluded. However, if patients are on therapeutic anticoagulation, and the deep vein thrombosis (DVT)/pulmonary embolism (PE) has been clinically stable or improved on anticoagulation for > 3 months, patients are eligible.

Pregnant women are excluded from this study because the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with lenvatinib, breastfeeding should be discontinued if the mother is treated lenvatinib. These potential risks may also apply to other agents used in this study

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and Toxicity | Toxicity as assessed by Common Terminology for Adverse Events version 5.0 will be evaluated descriptively using frequencies and percentages and will be reported using tables. All patients who receive treatment, regardless of eligibility, will be evaluated for toxicity. Toxicities by type and maximum grade over the course of treatment and follow up will be summarized and by date of occurrence. | through study completion, an average of 1 year |
